CHANGELOG_v5.mdon 15.10.2026 ~19:5x (file-size rotation, same house pattern as the v1 โ v2, v2 โ v3 and v3 โ v4 hand-offs). This file is preserved as history โ no new entries will be added to it; active changelog for version 1.9.20+ lives inCHANGELOG_v5.mdat project root.
This file supersedes
CHANGELOG_v3.md(rotated out on 01.10.2026 after the v3 file grew past a comfortable single-session read size (~67 KB / โ2 read chunks); same house pattern as the v1 โ v2 hand-off and the v2 โ v3 rotation of 20.09). At rotation, the ten newest v3 entries (the uncommitted rev-3x pile from FIX #33 through WALK-ABORT) were carried into this file verbatim; per owner order 01.10 (~21:xx), all of those pre-today entries have since been dumped back todocs/history/CHANGELOG_v3.md, where their bodies remain (the archive body was verified byte-identical before the dump โ rotation had left a duplicate copy, now deduped). This file now holds ONLY entries dated 01.10.2026 and later. New entries are added at the top of THIS file.
manifest.json revision advanced 0 โ 1 per the documented pure-rev-bump precedent, making the accumulated pile detectable for the pending Hub publish โ package.json version UNCHANGED (still v1.9.20); canon unchanged 74 suites / 1057 tests (manifest/docs-only entry โ zero code touched, gate trio not applicable)Context: since the rev-lock lift of 06.10 ~19:2x (package.json v1.9.18 โ v1.9.20 ยท manifest.json revision 33 โ 0), every entry carried "v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile)" โ local bytes moved continuously, but no Hub/GitHub publish ran since revision 30 (the last published to GitHub, 15.09). The owner order of today (~18:3x) is that long-pending publish GO, executed under the documented mechanic for making an update detectable: advance the manifest revision while the version stays fixed โ the same class as the v1.9.17-era pure rev-bumps (revs 29โ30โ31 so LM Studio detects the update) and the v1.9.16 bump (27โ28); the 06.10 unlock itself was a version move + revision reset, which this entry deliberately does NOT repeat.
Changes:
Scope boundary (explicit): this entry UNSTICKS the versioning state and documents it โ it does NOT itself perform a GitHub release / Hub push, dist rebuild or LM Studio reload; those remain owner-side steps exactly as in prior close-outs ("Remaining owner-side: dist rebuild + LM Studio reloadโฆ"). The pile now folding into that publish spans everything since 15.09 rev-30: FIX-35c ยท WALK-ABORT (in docs/history/CHANGELOG_v3.md after the 01.10 dump-back) ยท the 02.โ06.10 arcs (CTX-FOOTER โ i18n-CONFIRM / A3 / PLAN-SEAM, incl. the v1.9.20 rev-0 reset itself) ยท 05./07.10 PLAN-REMOVAL + the unlogged Arc-C sweep ยท 09.โ11.10 FIX #21 โ TOKEN-DIVERGENCE ยท 14.โ15.10 SESSION-MEMORY ARCS A/B/C (full 3-defect remediation closed owner-GREEN).
Versioning: this IS the versioning move โ revision 0 โ 1, first advance since the 06.10 reset; v1.9.20 rev-1 is now current state, sticky again only until the next explicit owner order (per the 21.09 standing rule: revisions change only on explicit instruction / Hub publish). Remaining carried items unchanged: restore-side hardening (candidate follow-up arc, needs fresh GO) ยท quarantine dir .pre-wipe-quarantine-20261014/ deletable only after a few confirmed-clean sessions ยท git footnote commit strictly last/opt-in.
Context: defect class C from the 14.10 forensics (recorded in the Arc-A top entry, deferred pending status verdict; owner ruling 14.10 ~18:15 DROPPED it as an open item and re-baselined it under this dedicated plan 15.10 โ scope locked to C1 + C2): two independent contamination paths into the session-memory pipeline. (C1) duplicate index rows โ SessionIndexManager.addEntry unconditionally prepended every write, so repeated persistence of one summary (e.g., tier-2 mid-loop save AND a PART-B close-out in the same turn) stacked byte-duplicate rows in .session_index.json, which restore re-surfaced N times. (C2) LLM-side artifacts leaking into persisted summaries โ generated continuation text carried __LM_STUDIO_INTERNAL_LSEP_* separator tokens, placeholder junk and reasoning preambles ahead of the real heading, round-tripping through future restores as if they were owner content. Design decisions fixed in-session: C1 overwrites IN PLACE within a bounded newest-row window (index stays chronological; constant + dated comment) instead of unbounded scan-dedupe; C2 strips at BOTH persist entry points โ before parse/persist/index, so the dirty text never touches disk on either path; C2a gates EMPTY-CONTENT runs (no meaningful user content in the toSummarize window โ skip generation entirely), mounted at the two Arc-C trigger sites only (contextGuard + promptPreprocessor) per the arc's step list.
Changes:
Tests: +1 suite / +6 tests: NEW tests/sessionIndexDedupe.test.ts โ pins the EXACT production guard expression (strict < WINDOW against disk arithmetic, not a paraphrase) across duplicate/no-duplicate/boundary shapes; expectations arithmetic-checked against the on-disk constant before handoff. The 16 in-file C2 strip+gate tests already written during the 14.10 handoff were carried UNGATED into this arc's first full gate โ they are part of the +22 delta, not new this session. Canon math per house rule: verified GREEN baseline 73/1035 (ARC-B owner re-gate 14.10 ~19:0x) + 16 ungated C2 tests + 6 new = EXPECTED 74 suites / 1057 tests โ the note "confirm 73/1035 unchanged" circulating in yesterday's pending items was arithmetically wrong about the C2 block and is hereby closed as such; do not repeat it. Zero other suites touched.
Verification: OWNER GATE GREEN (~18:2x, owner-run): full trio npx tsc --noEmit && npm run lint && npx jest โ tsc clean ยท full-src lint exit-0 ยท canonical npm test = exactly 74 suites / 1057 tests ALL PASSED in 21.3 s (preceded by the exact-match first pass at ~18:1x; delta vs pre-arc canon precisely +1 suite/+22, zero drift anywhere else โ the pre-existing 1035 confirm no regression). One lint observation closed as BY DESIGN: eslint flat-config ignores lists tests/, so a manually passed test file surfaces only an "ignored by pattern" warning (house lint scope is src-only via npm run lint = eslint src --ext .ts) โ zero errors either way, no config change required or made. Pre-gate statics: touched files parse-clean; in-sandbox tsc re-confirmed degraded (known limitation โ owner trio is the type gate); .bak baselines retained for all arc-touched files per house rule.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Docs swept same pass on the canon move: package.json description โ "1057 passing tests across 74 suites" ยท README badge/meta/comparison/test-command lines โ 74/1057 ยท ARCHITECTURE.md L1216 tests/ canon comment โ 74/1057 (prior-canon chains preserved). This closes defect class C and โ with Arc A (14.10) and Arc B (14.10) already GREEN โ the ENTIRE 3-defect session-memory remediation plan plan_1792077352864_cqqp13xco; remaining carried items: restore-side hardening (candidate follow-up arc, needs fresh GO) ยท quarantine dir .pre-wipe-quarantine-20261014/ deletable only after a few confirmed-clean sessions.
remove_plan), machine-tracked context entries accrued during its lifetime are retired, so a closed arc's pending items can never resurface as active in a future restore โ expected canon (+4 in-file; pre-arc 73/1031 per the Arc-A gate ~17:49) โ GATE GREEN ~19:0x (, owner-run re-gate; round-1 RED was this arc's own new test โ test-side baseline-capture defect, fixed same session): sandbox cannot execute tsc/jestContext: defect class B from the 14.10 forensics (recorded in the Arc-A top entry as deferred pending this arc): machine-written context entries that accrue during an arc's lifetime OUTLIVED their arcs โ auto-tracked gate decisions persisted scope:'global' with no close-out hook, so every session restore re-surfaced a finished arc's open items and they had to be deleted by hand (the 14.10 ~17:2x manual sweep is the incident instance). Owner GO "B" (~18:05) after Arc A went GREEN; design fixed in-session on two points: STRICT machine-entry predicate โ only entries that are tagged auto_track AND typed decision AND timestamped โฅ the closing plan's createdAt are ever eligible (explicitly recorded owner content has no machine tag and is NEVER auto-retired; pre-arc entries belong to earlier work), and best-effort wiring โ a context-store hiccup must never fail plan close-out itself.
Changes:
Tests: +4 tests in the EXISTING suite tests/taskPlanningTools.test.ts, new describe "supersede-on-close-out" (hermetic per house precedent โ isolated tmpdir working dir, REAL implementation via direct tool invocation): natural completion retires exactly the eligible machine entry while owner-decision and pre-arc entries survive on disk; remove_plan dry-run previews the count with a BYTE-IDENTICAL context store + plan file (pure-read proof); confirm removes plan + retires (survivor set pinned by id); zero-eligibility close-out performs ZERO writes (store byte-identical). Fixtures are REAL msgpack encoded through the production @msgpack/msgpack dependency (encode() import added to the suite) โ no mock stand-in for the storage format. Canon math per house rule: 73/1031 +4 in-file = 73 suites / 1035 tests (gate-verified ~19:0x โ see Verification).
Verification: GATE ROUND 1 (~19:0x, owner-run): canonical npm test = 73 suites / 1035 tests โ exactly ONE failure: the zero-eligibility byte-identity pin in this arc's own new describe (all other 1034 green incl. the three sibling FIX-B pins and the full pre-arc canon). Root cause TEST-SIDE ONLY, proven from source: the test captured its before baseline with fs.readFileSync(memPath) BEFORE its own eligibility rewrite (the deliberate re-seed that removes the only machine entry), so the byte-compare ran a 2-entry post-close-out store against a 3-entry pre-rewrite baseline โ guaranteed mismatch even though close-out performed zero writes (removeEntriesMatching short-circuits at matchedCount === 0 before any save; both production paths read-verified). Fixed same session: baseline capture moved BELOW the re-seed (one-line move + provenance comment); production code untouched. RE-GATE GREEN (~19:0x, owner-run): canonical npm test = exactly 73 suites / 1035 tests ALL PASSED in 20.8 s โ delta vs pre-arc canon (73/1031) is precisely the +4 in-file FIX-B describe, zero drift anywhere else; ESLint re-verified in-session post-fix = 0 errors / 0 warnings project-wide; npx tsc --noEmit confirmation still rides the owner trio (in-sandbox typecheck degrades to filesChecked=0 โ known limitation) โ risk assessed minimal: the only delta since round 1 is a one-line move inside an existing test, no new identifiers or types. Pre-gate statics done this session: ESLint via analyze_project = ; in-sandbox typecheck re-confirmed degraded (filesChecked=0 โ known limitation, owner tsc is the type gate); import soundness verified against live source ( + signature read-back); baselines retained for both touched files per house rule. Live expectation after the next dist rebuild: completing or removing an arc that accrued auto-tracked decisions logs exactly one line and future restores show no stale pending items from closed arcs; zero-eligibility close-outs are completely silent on disk (no store rewrite).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Remaining plan steps: C1 (index dedupe), C2 (empty-history gate + __LM_STUDIO_INTERNAL_LSEP_* artifact strip), restore-side hardening โ each its own gated arc.
Context: owner complaint ~17:08 that stale session memory resurfaced. Disk forensics over the quarantined pre-wipe store (memory-store-mirror-PREWIPE.json, 497 records) root-caused three defects: (A) all 401 context records scope:'global' with no TTL, 92% >7 days old โ pruneExpiredSessionEntries() had ZERO production callers (TTL enforced only on read paths), so machine checkpoints accumulated forever; family staleness flag measured newest-entry-only. (B) no supersede-on-close-out: closed arcs' pending lists resurfaced every restore; plans frozen at in_progress for days (deferred โ needs Arc-C status verdict first). (C) summary/index pipeline contamination + duplicate index writes (deferred, C1/C2). Owner GO full wipe ~17:15 โ store deleted, mirror QUARANTINED to .pre-wipe-quarantine-20261014/ (reversible; only recovery path until clean sessions confirm new behavior), post-wipe restore verified disk-clean. Arc discipline per house rule: one fix per gated arc โ this entry covers wipe + Fix A (+ the in-gate density restore below); Fixes B/C1/C2 follow their own gates.
Changes:
Tests: +1 suite / +5 tests total: NEW tests/contextLifecycleFixA.test.ts, 4 tests (hermetic, real tmp msgpack fixtures per house precedent): (1) inline reap of expired session-scoped entries on the next addEntry; (2) retention cap prunes oldest non-decision substantive entries beyond 100 with decision exemption even when a decision is the oldest entry; (3) checkpoint-tagged entries never count against the cap AND are TTL-reaped like any session entry; (4) fresh session-scoped entries pass through untouched. +1 in-file test in tests/autoTracker.test.ts ("FIX-A (14.10): checkpoint entries are written session-scopedโฆ") pinning the EXACT production input shape delivered to addEntry by autoSaveSessionMemory() (house rule โ LEVER-1 no-op lesson): records through an injected recording ctor (the suite's jest.mock factory is a plain class, not a jest.fn โ first gate RED was this test-side assumption; fixed same session), asserting one entry per save with scope:'session', tags:['auto_checkpoint','token_threshold'], type:'summary', id regex ^ctx_\d+_checkpoint$. Canon math: pre-arc canon 72 suites / 1026 (owner-GREEN 10.11 ~20:1x) + 1 suite/+4 + 1 in-file = 73 suites / 1031 tests; zero other suites touched.
Verification: GATE ROUNDS (all owner-run): pre-flight (~17:43, three named suites): autoTracker.test.ts full PASS incl. the rewritten FIX-A case ยท contextLifecycleFixA 4/4 with production behavior proven live in-suite ([ContextStorage.addEntry] Retention cap: pruned 5 oldest non-decision substantive entries (> 100) + decision-exemption pins) ยท fix20_midloop_token_counting exactly the three density-pin failures (the documented group B โ everything else green). Full gate after the density restore (~17:49): npx tsc --noEmit clean ยท npm run lint "0 problems" ยท canonical npm test = 73 suites / 1031 tests ALL PASSED โ delta exactly +1 suite/+5, zero drift anywhere else (the pre-existing 1026 confirm no regression). Pre-gate statics: touched files parse-clean; grep due-diligence proved fix20 is the ONLY suite repo-wide pinning exact density arithmetic (all other estimateTokensFromChars consumers assert relatively โ verified by this GREEN run under restored รท3.2); both .bak baselines retained for the arc sweep.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Docs swept same pass on canon move: package.json description โ "1031 passing tests across 73 suites" ยท README badge/meta/comparison/test-command lines โ 73/1031 ยท ARCHITECTURE.md tests/ canon comment โ 73/1031 (prior-canon chains preserved). Open owner items carried: Arc C status (src/sessionSummaryPersist.ts exists in tree โ done/dropped/pending? gates Fix B's close-out work) ยท quarantine dir .pre-wipe-quarantine-20261014/ deletable only after a few confirmed-clean sessions (mirror = sole recovery path meanwhile) ยท remaining plan steps: Fix B (supersede-on-close-out), C1 (index dedupe), C2 (empty-history gate + __LM_STUDIO_INTERNAL_LSEP_* artifact strip), restore-side hardening, then handoff.
Current release: v1.9.20 (package.json + manifest.json; revision 1 โ UNSTICKED on owner order "unstick v1.9.20 rev 0" 15.10 ~18:4x, revision advanced 0 โ 1 per pure-rev-bump precedent; rev lock originally lifted by owner decision 06.10 ~19:2x; revision 30 was the last published to GitHub, 15.09): the accumulated rev-3x pile (FIX-35c, WALK-ABORT, the 01.10 CONTAMINATION-FIX + jest flag-independence arc, the 02.โ06.10 arcs below) now folds into the v1.9.20 Hub publish โ pre-today entries of the pile live in docs/history/CHANGELOG_v3.md after the 01.10 dump-back. Newest arcs: SESSION-MEMORY ARC C (top entry, 15.10 โ owner-GREEN ~18:2x trio: final defect class of the remediation plan closed โ C1 index-dedupe guard in SessionIndexManager.addEntry + C2a empty-history gate at both Arc-C trigger sites + C2b artifact strip at both persist entry points; canon 73 suites / 1035 โ 74 suites / 1057 tests) + SESSION-MEMORY ARC B (14.10 โ owner-GREEN ~19:0x: supersede-on-close-out shipped โ arc/plan close-out retires machine-tracked context entries accrued during the arc's lifetime so closed arcs never resurface as active pending items; strict auto_track+decision+โฅcreatedAt predicate, best-effort wiring, dry-run preview on remove_plan; canon 73 suites / 1031 โ 1035 tests) + SESSION-MEMORY ARC A (14.10 โ owner-GREEN: stale session-memory store wiped per owner GO + context-entry lifecycle shipped โ auto-checkpoints written scope:'session' (24h TTL applied downstream), inline expired-session reap on every write, substantive-retention cap 100 with decision exemption; companion restore of the undocumented agentic-density flip 3.5โ3.2 caught in-gate; canon 72/1026 โ 73 suites / 1031 tests) + TOKEN-DIVERGENCE ARC (10.11 โ owner-GREEN: the token estimator now measures instead of guessing โ replaces the unmeasured ร0.25 charsโtokens heuristic with a live-probe-derived agentic density, and per-locale wire-shape credit corrects schema-byte estimates; canon ) + TWO-TIER ARC CLOSE-OUT โ FIX A + FIX B (10.10 โ owner-GREEN: mid-loop threshold crossings now arm a one-shot user-visible ack-only notice, and pre-emptive forced COMPRESSION runs at a FIXED 95% of the window between tier-2's @~90% save and the 100% stop) + TWO-TIER MID-LOOP FORCED SAVE / FIX #21 (09.10 โ tier-2's forced @ session-memory save now fires mid-tool-loop in the wrapper: save-only, once per turn, non-fatal; owner-GREEN) + LEVER-1 (08.10 ~20:0x โ wire-payload arc closed on a live root-ZodObject pre-check, ฮ = โ1,326 param chars (โ3.55%); canon ) + the unlogged Arc C sweep of 07.10 (+3 suites / +35 tests: โ its own entry never landed; lineage gap flagged in the LEVER-1 entry) + DOC-PIN (06.10 ~21:xx โ registry-vs-docs drift gate as a new hermetic jest suite; canon ) + TOOL-DOC-SYNC (06.10 ~20:0x) + i18n-CONFIRM (06.10 โ confirmation prompts display the configured ๐ language's option words; reply acceptance covers ALL shipped locales) + A3 CLOSE-OUT / PLAN-SEAM / F1 WORDING (06.10) โ full digest after the top entries; canon since the 15.10 SESSION-MEMORY ARC-C gate GREEN (~18:2x owner-run); prior canons 73/1035 (SESSION-MEMORY ARC-B, 14.10 ~19:0x) ยท 73/1031 (SESSION-MEMORY ARC-A, 14.10 ~17:49) ยท 72/1026 (TOKEN-DIVERGENCE, 10.11 ~20:1x) ยท 71/1020 (TWO-TIER CLOSE-OUT, 10.10 ~12:05) ยท 69/1003 (FIX #21, 09.10 ~18:1x) ยท full chain in the top entry (the 28.09 FIX-35c/WALK-ABORT arcs sit in archive per the note above).
Context: the live probe of 10.10 (verbatim 2,527-char session sample โ 787 prompt_tokens on qwen3.8-27b-ud at ~88% window fill โ 3.21 chars/token measured against this plugin's actual agentic mix: prose + JSON tool output + code + log) exposed that every consumer of estimateTokensFromChars() โ mid-loop deltas, the CTX-FOOTER projection and both tier gates โ was dividing by an UNMEASURED ร0.25 (+10% buffer) heuristic (4 chars/token assumed): dense payloads ran ~12โ18% hotter than every gate believed, silently shrinking the effective safety margin below the 75%/90%/95% rungs. Class B: the wire-shape credit โ per-locale schema byte estimates had no correction for locale-dependent description length (de/es/zh variants measure wider), so projection math over foreign-locale schemas mis-sized by a deterministic per-call amount. Both defects share one root shape: an estimated constant standing in for a measurable quantity (house precedent: Lever-1, 08.10).
Changes:
src/utils/tokenStatsManager.ts: NEW exported constant AGENTIC_CHARS_PER_TOKEN = 3.2 with provenance comment (probe sample size, model id, window fill %, date); the heuristic path now divides by this constant with ceil instead of ร0.25ร1.10 floor โ single source of truth for every estimation consumer (mid-loop delta via recordToolResult, CTX-FOOTER projection in the wrapper, tier-1/tier-2/compact trigger math). The precise tiktoken path is untouched: measured BPE still wins wherever it runs; only the fallback/estimation floor changed. No new config key (house stance โ a constant with provenance beats an unmeasured dial).Tests: ONE NEW hermetic suite pinning: the constant + its provenance comment, the ceil-division contract on exact boundaries (a one-char payload must never undercount below the probe floor), consumer wiring (mid-loop delta / projection consume the SAME divisor โ no second heuristic site may exist) and the locale-shape credit table incl. EN-zero. Canon math per house rule: pre-arc canon 71 suites / 1020 (owner-GREEN, 10.10 round 3) + this arc's one new suite with its six cases = 72 suites / 1026 tests โ zero other suites touched; the final GREEN run confirms it with zero drift anywhere else.
Verification: GATE ROUNDS (owner-run): pre-final rounds RED on three failures โ all test-side pins of this arc's new suite, root-caused and fixed same session (contemporaneous gate records ~20:0x); per-pin specifics not preserved in the durable record. The round at ~20:05 then ran GREEN for those three plus ONE additional failure in tests/stateManagerRace.test.ts B1 โ a suite this arc NEVER touched, green at ~19:58 โ assessed an intermittent race flake; passed on re-run before final. All fixes test-side only; src untouched between rounds. FINAL GATE GREEN (~20:1x): canonical npm test = exactly 72 suites / 1026 tests ALL PASSED ยท npx tsc --noEmit clean ยท lint "0 problems". Statics: edited files LF/noBOM verified per edit; constant + credit table grep-verified single-sourced (zero surviving ร0.25 heuristic sites in live src). Live expectation from the next dist rebuild onward: dense agentic turns project ~12โ18% hotter than pre-fix โ tier crossings and footer percentages read closer to real window fill; healthy turns shift identically in absolute terms, so no new early-fires are expected at the 75%/90%/95% rungs (the margins were under-sized before, not over-sized).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Remaining owner-side: dist rebuild + LM Studio reload to ship live ยท git footnote commit strictly last/opt-in ยท docs sweep (this close-out) landed same pass: package.json description, all five READMEs (badge + meta line + comparison row + test-command comment), ARCHITECTURE tests/ canon comment, GLOSSARY status/canon rows + new "agentic density" entry.
Context: Root causes proven from source (09.10 verification session): (A) guardMidLoopThreshold armed NO state across turns โ "notified on next message" was only a console.log while the FSM re-evaluated usage fresh each turn, so any crossing followed by compression or a context-window increase dropped below threshold with zero user-visible mention (the owner never saw today's 75%+/92.2% checkpoints in chat); (B) between tier-2's @~90% forced SAVE and the model's 100% hard stop NOTHING ran mid-loop โ saves persist memory but never shrink context, and compressHistory() was reachable only at user messages โ run-away turns died at the wall twice in one day until the owner enlarged the window. Owner GO "A and B" (09.10 ~19:2x). Design decisions on record: 95% as FIXED constant, NOT a config key (house stance; deriving from compressionPercent would lose protection if the user sets schema max 100); two INDEPENDENT once-per-turn latches (@~90% save / @95% compaction โ neither suppresses the other; after a successful compression the republished baseline drops later projections under both gates anyway); compressMidLoop lives in contextGuard.ts to avoid widening the documented-safe promptPreprocessorโtoolsProvider cycle (grep-proven cycle-free); host-history swap duck-typed + non-fatal.
Changes:
Tests: NEW suite tests/fixA_midLoopNotice.test.ts, 6 tests (arms-on-success with usage-at-crossing + checkpoint-id pins, silent below threshold, failโretry arms exactly one notice, FSM-untouched contract, latest-crossing-replaces-not-stacks across the hysteresis floor, survives onContextCompressed() without swallowing an armed notice) and tests/tierB_midLoopCompaction.test.ts, 11 tests (fires-once at projected โฅ limitร95/100 with PART-parity opts + host-history swap + recount republish; INCLUSIVE exact boundary via the wrapper's own estimation math โ est(100 chars)=28, FOOTER_TOKEN_ESTIMATE=25 โ and silent one token below; 90โ95% band silence; once-per-turn idempotency; INDEPENDENCE from tier-2 (both fire in one โฅ95% pass); โค10-msg skip with latch hold same-turn; stub-guard-without-method silent skip while tier-2 on the SAME fake fires; rejection non-fatality; compressed:false โ no swap/no recount/deterministic log; strict-gate matrix) โ zero other suites touched. Both suites were written 09.10 (arc tail) but gated for the first time in this arc's rounds.
Verification: GATE ROUNDS (all owner-run): round 1 (~11:5x): tsc RED at src/toolsProvider.ts L588 โ TS2345 from Fix-B's as unknown[] downcast on the recount call (countTokens declares ContextMessage[]; the cast broke assignability). Fixed by REMOVING the cast (compressMidLoop's return already types outcome.messages) + in-file provenance comment; eslint 0/0 post-fix. Round 2 (~12:0x): tsc clean ยท lint clean ยท jest 71 suites / 1019โ1 โ sole failure in NEW suite fixA_midLoopNotice test-3 (retry.fired === false), root-caused as a HARNESS defect with production untouched (proven from source): the test called TokenStatsManager.resetMidLoopDelta() before its same-turn retry โ that hook is preprocess()'s NEW-TURN reset which by documented design zeroes baseline AND limit, so getTurnBaseline() read 0 and the retry evaluated at 12.3% usage < 75 threshold (below-threshold gate, never reaching hysteresis); production's save-failure rollback _midLoopGuardedAt โ 0 (autoTracker.ts L481โ483) is correct as-is โ its comment explicitly rejects the baselineTokensโ1 alternative. Fixed by deleting the line + a three-line production-shape comment; audit of the suite's other resetMidLoopDelta() use (test-5) confirmed safe (passes literal baselines, never reads state back). Statics: all touched files LF/noBOM verified per edit; project-wide eslint 0/0 after each fix. clean ยท lint "0 problems" ยท canonical = exactly โ zero drift elsewhere (the pre-existing 1003 confirm no regression). First LIVE Fix-A firing of the arc: owner confirmed YES to the tier-1 checkpoint at ~79% mid-close-out (~12:1x) โ the notice machinery under test exercised itself against this very conversation.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending). SHIPPED LIVE 10.10 ~13:1x โ owner dist rebuild (~13:08 local, dist/index.js mtime-verified) + LM Studio install/reload same day; both fixes verified present in the shipped bytes (Fix A notice literal @L56991 ยท 19 [TIER-2-COMPACT] telemetry lines incl. the wrapper โ
success line @L60885). Live-signal watch: one ๐ MID-LOOP CONTEXT THRESHOLD NOTICE ack on the next successful mid-loop crossing + exactly ONE [TIER-2-COMPACT] โ
Pre-emptive mid-loop compression complete per 95%-crossing turn ยท git footnote commit strictly last/opt-in. Plan plan_1791566441631_k9zi1jqqq closes with this entry + the zero-.bak sweep; provenance for the two gate-round fixes = memories of 10.10 (~11:5x cast, ~12:0x harness).
Context: tier-2's forced save existed only at user-message boundaries (PART B, promptPreprocessor), so inside a long tool loop it never fired and window usage could run past 100% before the next message โ nobody is listening mid-turn to answer tier-1's interactive prompt. Owner spec (supersedes the earlier 95%-key design; do NOT resurrect): reuse contextGuardCompressionPercent + contextGuardEnabled, no new config, SAVE ONLY with NO terminal-stop semantics. The wrapper already computed a shared CTX-footer projection per pass โ that became the trigger mount, so footer and tier-2 gate on one provably-identical "current usage" number with independent toggles (the pre-fix defect class was tier-2 nested UNDER the contextUsageFooter toggle: footer OFF silently disabled the save). SDK audit confirmed no plugin-side stop lever exists (@lmstudio/sdk d.ts: abortSignal/ToolCallContext.signal listen-only) โ consistent with spec.
Changes:
Tests: NEW suite tests/tier2MidLoopSave.test.ts, 13 tests / zero other suites touched โ canon 69 suites / 1003 tests. Pins: fires-once + persist of the keepLast slice (25 msgs โ generate gets exactly m0โฆm14); INCLUSIVE >= boundary at EXACTLY limit*percent/100 (exact-baseline construction vs the wrapper's own math) and silent one token below; once-per-turn idempotency across 3 results + re-arm on a NEW provider run (= new turn, 2 fires total); strict-gate matrix ([false, 0, undefined]) and percent-gate matrix (['90', 0, -10]) all silent at crossed threshold; save-failure non-fatality (persist {saved:false} โ result intact + โฅ1 [TIER-2] telemetry line); span-guard skip (12 msgs โ deterministic "nothing summarizable" log, LATCH holds when the list later grows to 30 same turn); null-list publish (?? [], no throw); footer-OFF independence; suppression-warn regression pin (warn exactly once per window, re-arm on live baseline).
Verification: GATE ROUNDS (all owner-run): round 1 (~16:4x): tsc RED at src/toolsProvider.ts โ the Step-4 lift-up had left an ORPHANED pre-#21 outer try/catch tail + one stray brace behind (the "re-nest" fix class; ground truth for the byte-equivalent suppression-warn re-expression = shipped original in dist/index.js L58537โ58577, read from disk since no git access). Fixed same session โ round 2 GREEN (tsc ยท lint 0 ยท canon unchanged 68/990; the two micro-fixes: redundant cast removal + jest RC#4 mapper entry above). Tier-2 went LIVE in production ahead of close-out (owner rebuild+reload ~17:2x, trigger ON) โ live signal = exactly ONE [AI Toolbox] [TIER-2] line per 90%-crossing turn. Round 5 (~17:5x): canon as pinned 69/1003 โ 3 failures, all in the NEW suite: F2 (โค10-past-keepLast fired generate([m0,m1]) โ root cause proven from failure output + code: guard turnMessages.length > 10 on a 12-msg list; correct predicate derived against ALL suite pins = fire iff (len โ keepLast) >= keepLast, INCLUSIVE at len=20 because tests 1/5/6/9 pin firing AT makeTurnMessages(20) โ naive variants would break passing tests); F1/F3 (result === undefined). Fix half-applied at session end (use-before-declaration intermediate state).

Rewritten to direct + value pins = house style; zero other suites affected. clean ยท lint "0 problems" ยท canonical = exactly โ zero drift elsewhere (the pre-existing 990 confirm no regression). Statics: all edited files LF/noBOM verified; structural audit of the final wrapper block via corrected state-aware brace census = net-zero, anchor-verified (two earlier scanner passes false-alarmed on the single-line template @L433 โ pitfall recorded in memory).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate). Plan plan_1791486516504_18lot11bd closes at step 8 (self-audit vs git baseline c1b4ca5 + zero-.bak sweep) on this GREEN gate. Remaining owner-side: dist rebuild + LM Studio reload to ship the corrected span-guard tier-2 (the ~17:2x live build predates it โ behaviorally near-identical in practice, but the shipped bytes should match the gated src; live verification after = exactly one [TIER-2] line per 90%-crossing turn; a short-list skip-log on a crossing with <20 published messages is expected telemetry, not a defect) ยท git footnote commit strictly last/opt-in.
minifyTool gains an _def.typeName === 'ZodObject' pre-check + one-node walk; canon 68 suites / 987 โ 990 tests (same suite file, +3 tests) โ GATE GREEN ~20:05 (tsc clean ยท lint "0 problems" ยท 990/990 ALL PASSED in 22.3 s, owner-run; wire harness ฮ = non-zero after two zero-delta rounds)Context: Lever-1's truncation pass shipped RED: the owner's first wire-harness re-run measured EXACTLY ZERO delta on 37,373 param chars (โฅ49 of 218 described fields were expected to lose bytes). Root cause proven with a file-level evidence chain (forensics memory memory_1791481751431): the SDK's tool() stores params as a LIVE root ZodObject (parametersSchema = z.object(rawShape), @lmstudio/sdk/dist/index.mjs ~L11353); v3 instances carry NO own .type/.properties, so the minifier's serialized-root branch can never match them and its per-entry fallback iterated the instance's ~29 ctor props without ever opening _def.shape() โ zero truncation. Jest was blind: 68 suites / 987 tests green with no test covering that exact input shape โ the lesson (tests must pin the EXACT production input shape, not just per-field/serialized forms) is now embodied in this arc's new tests, which caught a SECOND silent no-op one level down (see Verification round 1). Owner pick: Option A (minimal-scope pre-check; live-Zod constraint capping deliberately OUT of scope โ parked pending llama.cpp PR #17381 exposure audit + explicit GO).
Changes:
Tests: +3 tests in the EXISTING suite tests/toolsSchemaMinifier.test.ts (new describe "LIVE root ZodObject โฆ harness-zero-delta regression"): (1) end-to-end truncation through a live z.object(rawShape) passed as parametersSchema โ depth-1 fields (hard cut 83 / sentence-boundary cut 76), nested .optional() z.object field via _def.innerType, z.array(z.object()) element fields via _def.type, โค80-char describes byte-untouched, pass-through identity (minified.parametersSchema === schema) + validation accept/reject intact; (2) re-registration idempotency โ second pass over the SAME shared live schema is byte-stable; (3) guard negative space โ per-field shape records and serialized roots still route to their ORIGINAL branches (serialized-root maxLength 5000 โ 2000 cap proven to still land on the returned copy). Canon math: pre-arc canon 68 suites / 987 tests (owner-gate verified 08.10 round 2) + 3 in-file tests = 68 suites / 990 tests; zero new files/suites, nothing else touched. CANON LINEAGE NOTE: the DOC-PIN top entry below closed at 65/952 โ the intervening +3 suites / +35 tests belong to the Arc C sweep of 07.10, whose own changelog entry is NOT present in this file (gap flagged to owner at handoff; mtime 07.10 ~16:16 suggests an attempted write that never landed).
Verification: round-2 pre-gate statics (post-fix): full read-back of both files LF/noBOM; verbatim port of guard + walk executed in-sandbox against the repo's own zod 3.25.76 = 15/15 PASS, covering every jest assertion plus negative cases. GATE ROUNDS (all owner-run): round 1 (~19:58): build ESM+DTS green ยท npx tsc --noEmit clean ยท lint clean โ but 2/990 RED, both in this arc's new root-Zod tests: the first guard draft read INSTANCE .typeName (undefined on v3) โ silently fell back to the per-entry path again (failure #2's "Received Object" = plain-object reconstruction of the ~29 ctor entries โ direct proof). Fixed same session to _def.typeName. Round 2 (~20:03): canonical npm test = 68 suites / 990 tests ALL PASSED in 22.3 s โ both former REDs green, zero drift elsewhere (the pre-existing 987 confirm no regression). Wire harness (node scripts/wire_harness.cjs both, ~20:05): baseline โ current = tools 81 โ 81 ยท param chars 37,373 โ 36,047 (โ1,326 / โ3.55%) ยท desc chars 10,649 โ 10,649 UNCHANGED โ all savings concentrated in the target zone with tool-level truncation untouched, exactly per contract; parametersSchema key seen ร81 confirms the measured path is the real SDK one, and the non-zero delta empirically proves mutation surfaces through the host's serialization (a cloning host would have shown zero). The 1.3k figure matches the field distribution: only describes >80 chars lose bytes; many cut early at sentence boundaries; the 81โ89 tail sheds few chars each.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate). Close-out executed in-queue: arc .bak sweep done (src/toolsSchemaMinifier.ts.bak, tests/toolsSchemaMinifier.test.ts.bak removed; 12 PRE-EXISTING stale .bak files from earlier arcs left untouched โ flagged for owner decision, not swept unilaterally). Remaining owner-side items: dist rebuild + LM Studio reload to ship live (the harness already ran against the post-fix build) ยท git footnote commit strictly last/opt-in ยท Arc C 07.10 changelog-entry gap (see Canon lineage note) ยท parked: live-Zod capMaxLength/capItems blindness (wire still carries constraint values >2000, e.g. max_lines: 5000) behind PR #17381 audit + explicit owner GO.
Context: the TOOL-DOC-SYNC arc's root cause was structural โ nothing validates registry-vs-docs drift (tsc/lint/jest cover code+tests only) โ and its close-out deferred exactly this gate by explicit owner decision ("1"). Owner GO ~20:4x. Suite authored in a dual-writer session (this instance debugged it through 3 owner-run gates). Two defects root-caused between the first REDs and GREEN: (1) jest mapper RC#4 โ jest.config.cjs gained one per-file entry (attachmentManager, L172โ173); (2) T2's heading matcher bled into tail prose โ stripDecor() strips parens, so its paren-skip logic could never fire and File System L35's "(24 โ incl. โฆ folded in from Text Processing, 23.09 Q6)" admitted "text processing" โ 24 (the Data Visualization line was the separate adjudicated figure). Owner adjudication "a+a": (a) TOOLS_REFERENCE ยงData Visualization keeps its deliberate chart-only (1) โ test-side skip, no doc edit; (b) README L151's Data-Viz row gains backticked siblings markdown_preview + get_repeat_tool_advice (the R4/R5 inline path).
Changes:
Verification: pre-gate statics: byte-simulation of the final matcher over all 25 live ## headings = zero unexpected mismatches, incl. both flagged risks โ Context Management 22 declared == 22 pins; Backup & Restore (6 rows below) parses leading int 6 == 6. Per-file EOL/BOM verified post-write: test file pure LF/noBOM (unchanged by edits); README/jest.config per house baseline.

Live effect from now on: any tool shipped without a doc surface โ or any family whose declared count diverges from live code โ REDs this gate in npm test; the TOOL-DOC-SYNC / stale-bundle drift class gains its structural feedback loop.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate).

Canon counts (64 suites / 941) and version stamps (v1.9.20 / manifest rev 0) verified CURRENT in every live doc (README L7/L48/L103, ARCHITECTURE.md L127+L1138, DOCUMENTATION.md header, package.json description); historical entries (CHANGELOG_v4 bodies below the top line, docs/history/*, RELEASE_NOTES.md) untouched per house rule. Exactly ONE real stale cluster found โ and it was the remove_plan gap the owner then pressed on ("das tool existiert !!!!"): the tool shipped GREEN 05.10 (PLAN-REMOVAL arc; canon move 63/931 โ 64/938) and is live in production dist since today's ~18:2x rebuild, yet was absent from both tool-inventory docs โ TOOLS_REFERENCE.md (ยงTask Planning "(3)", overview row "Task Planning | 3", no tool row; update_plan_step row lacked the auto-removal behavior) and README.md family table ("๐ Task Planning | 3"). ROOT CAUSE (three links): (1) the PLAN-REMOVAL close-out's docs sweep covered ONLY its declared current-state canon lines (README L7/L48/L103, ARCHITECTURE L1138, package.json description); (2) tool-inventory doc updates were never a step in any arc's close-out checklist; (3) no feedback loop exists โ the owner gate trio (tsc / lint / npm test) validates code + tests only, so registry-vs-docs drift is structurally invisible to every gate. Same failure class as the 06.10 stale .lmstudio/ bundles: nothing verifies, it was documented "in passing".
Changes: docs-only โ NO src/tests touched (canon delta zero by construction):
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the next Hub publish with the rest of the pile (footnote-level per the standing mandate). Remaining owner-side items unchanged: git footnote commit (strictly last/opt-in) ยท Hub publish decision.
Context: the AutoTracker threshold flow's YES/NO confirmation prompts (promptPreprocessor.normalizeConfirmationReply + the two project-switch banners + autoTracker.checkAndGeneratePrompt warning) hardcoded English option words with a legacy bilingual 'yes'/'ja' fallback โ inconsistent for owners running any of the four non-EN ๐ Language settings. Owner verdict A: DISPLAY in ONLY the configured language (never bilingual); ACCEPT replies in ALL shipped languages by design (a config=en user may still answer JA). The union is derived from the locale files at load, so a future locale extends acceptance automatically โ one source of truth. FSM logic untouched by construction.
Changes:
Tests: +3 tests / zero new suites: tests/cwdConsistency.test.ts +2 (all-language acceptance cases incl. Sร/็กฎ่ฎค/็ขบ่ช + negative case); tests/autoTracker.test.ts pinned-wording assertion updated ('Reply 'YES'' โ no longer 'YES'/'JA') + 1 new it (localized display, fresh tracker per case to defeat pending-warning caching). A repo sweep found the old wording only in .bak / stale-bundle artifacts (.lmstudio/dev.js, production.js) โ owner rebuilds dist; those are not live sources. Canon math: pre-arc canon 64/938 + 3 cases = 64 suites / 941 tests; nothing else touched.
Verification: pre-gate statics this session: ESLint src/ = 0 problems (in-sandbox; sandbox tsc degrades to filesChecked=0, so the real type gate rides the owner trio). GATE GREEN (~19:1x, owner-run): npm run lint no problems ยท npm run typecheck (tsc --noEmit) clean exit ยท canonical npm test = exactly 64 suites / 941 tests ALL PASSED in 24.37 s โ the expected +3 landed with zero drift anywhere else. Live expectation: nothing user-visible until the owner's next dist rebuild + LM Studio reload (.lmstudio/production.js still carries the pre-arc wording; running instance otherwise unaffected).
Versioning: rev lock LIFTED on owner decision 06.10 ~19:2x โ package.json v1.9.18 โ v1.9.20, manifest.json revision 33 โ 0; this arc is the first entry under v1.9.20 rev 0 (owner publish pending; rev 30 was the last published to GitHub, 15.09). Canon docs swept in the same pass: README meta line + comparison table + test-command comment โ 64/941 ยท package.json description โ "941 passing tests across 64 suites" ยท ARCHITECTURE.md version stamp (v1.9.20 / manifest rev 0) + tests/ canon comment (canon since i18n-CONFIRM, prior-canon chain completed with the 64/938 step). Plan plan_1791306127867_gygh8zb3r closed end-to-end on this close-out (auto-removal at natural completion).
Context: the A2/A3 CSM write-back arc (implementation + forensics done 04.10 โ save() opts / saveCore union / _isOutOfScopeForSave, explicit-wipe flags on clearAll + removeCrossProjectEntries, root cause pinned: load() scope-filter + save of loaded-list only wiped foreign-stamped ctx on every default save) was implemented and read-back-verified, but its verification gates were owner-run items the 04.10 session could not execute from sandbox (child_process statically blocked; in-process typecheck filesChecked=0). The plan had persisted at 2/6 with steps 3โ5 pending "RUN next session" โ an orphan relative to the later PLAN-REMOVAL + PLAN-SEAM arcs, which re-gated the full canon daily. Today (06.10 ~18:1x) the owner ran all three gates plus a lint belt-and-braces after the PLAN-SEAM close-out; this entry records that closure with verified counts only.
Verification: OWNER GATES GREEN (all 06.10 ~18:2x, owner-run): npx jest csmNonDestructiveSave = 7/7 passed in 0.62 s โ E1, the pre-fix-failing pin (foreign-stamped record wiped on default save), green; regression trio csmSharedFileRegression | stateManagerMemoryFile | restoreSessionContext = 2 suites / 21 tests ALL PASSED in 0.89 s โ A3 regresses none of the FIX #2/#23/D-RACE contracts; npx tsc --noEmit -p tsconfig.json = clean exit (0 errors); extra belt-and-braces npm run lint = "0 problems" (ESLint zero-finding exit).

Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Plan plan_1791101285283_ojyfcs9fb closed end-to-end on this close-out (6/6 โ natural-completion auto-removal from .ai_toolbox_plans.json; provenance here + in session memory).
PlanStorageManager's plugin-root mirror + fallback second store removed โ the CURRENT working dir's .session_context/.ai_toolbox_plans.json is now the SINGLE plan store; all test-only scrub workarounds that existed solely because of it deleted; canon unchanged 64 suites / 938 tests โ GATE GREEN ~18:0x (tsc clean, lint "0 problems", 64/938 ALL PASSED in 23.4 s, owner-run)Context: the PLAN-REMOVAL arc's first gate round (05.10 ~18:3x) went RED on cross-suite contamination proven to run through a PRE-EXISTING PlanStorageManager seam, not the new code: under jest every save() mirrored to <rootDir>/src/.session_context/โฆ (pluginRootPath captured from __dirname; in built dist that resolves to the plugin root) and every empty-working-dir load() fell back to that same mirror file. The repo-store guard protects only the LIVE <rootDir>/.session_context, so the src-mirror was unprotected test residue โ self-contained as long as no earlier-running suite polluted it (the PLAN-REMOVAL suite's 7 creates leaked via the fallback into later suites' isolated dirs; cwdConsistency.test.ts documented the convention with its own afterAll cleanup). The arc close-out had carried this as the optional P3 follow-up "kill the seam at source โ needs GO". Owner GO: remove the second store entirely rather than guard it. Design decision recorded in-session: SINGLE-STORE semantics over dual-store+guards โ plans live exactly where CWD says; on a project switch an empty new working dir shows no plans (matches FIX #3's per-call resolution intent) and the cross-project/cross-suite leakage path is eliminated by construction, not policed.
Changes:
Tests: NONE ADDED OR REMOVED โ this arc removes workaround code ONLY; no assertions added or deleted, so 64 suites / 938 tests is the deliberate invariant and zero count change was the gate expectation. The two previously-leak-prone suites (taskPlanningTools, cwdConsistency) run hermetic by construction now: nothing can reach a foreign store because none exists outside the working dir.
Verification: pre-gate statics this session: per-file .bak baselines created first (house rule), each change diff-audited in-scope against its baseline; EOL/BOM verified post-write per file (byte census 06.10 ~18:1x: src/tools/taskPlanningTools.ts pure LF [CRLF=0 / lone-LF=503] + tests/taskPlanningTools.test.ts LF โ both noBOM; tests/cwdConsistency.test.ts CRLF + jest.global-teardown.js CRLF, noBOM); ripgrep sweep across src/ + tests/ clean of pluginRootPath / scrub symbols in live code (residual hits confined to the four .bak baselines themselves). GATE GREEN (~18:0x, owner-run): npx tsc --noEmit clean ยท npm run lint "0 problems" ยท canonical npm test = exactly 64 suites / 938 tests ALL PASSED in 23.4 s โ zero drift vs the F1/PLAN-REMOVAL canon, confirming the delta-zero expectation. Live note: dist/ + .lmstudio/production.js still carry the pre-seam (mirror) build until the owner's next rebuild+reinstall โ functionally harmless in production today (the mirror was a second write of identical content), but single-store behavior goes live only after that rebuild; decision parked with the owner.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). The PLAN-REMOVAL arc's optional P3 follow-up ("kill the seam at source") is hereby CLOSED end-to-end; both earlier design verdicts (auto-removal as-is, no toggle / provenance trade-off accepted) remain closed and are NOT re-opened here.
Newest arcs: i18n-CONFIRM (top entry, 06.10 ~19:1x) โ confirmation prompts display the configured ๐ language's option words; reply acceptance covers all shipped locales via a union derived from locale files (canon 64 suites / 938 โ 941 tests; first v1.9.20 rev-0 entry); A3 CLOSE-OUT (06.10 ~18:2x) โ the 04.10 CSM write-back arc's deferred owner gates ran GREEN (7/7 ยท regression trio 2 suites/21 tests ยท tsc clean ยท lint "0 problems"), plan auto-removed at 6/6; verification closure only, zero code change, canon unchanged 64 suites / 938 tests; PLAN-SEAM (06.10) โ PlanStorageManager's plugin-root mirror + fallback second store removed; the working dir's .session_context/.ai_toolbox_plans.json is now the single plan store and all test-only scrub workarounds deleted (seam removal only, canon unchanged 64 suites / 938 tests; SHIPPED โ dist rebuild ~18:15 local + LM Studio reinstall/reload same day, owner-verified running instance); F1 WORDING micro-arc (06.10) โ checkpoint-saved notice body reworded to truth-aligned telemetry phrasing (string-only, canon unchanged 64 suites / 938 tests); PLAN-REMOVAL (05.10) โ completed plans auto-removed from the working-state store at natural completion + explicit confirm-gated remove_plan tool for unfinished plans; root-cause fix of the 29-stale-plan accumulation, canon gate moved to 64 suites / 938 tests; THRESHOLD-MARKER WORDING (05.10) โ owner re-voicing of mid-loop threshold-marker logs + stored record text ("threshold reached โ user notified on next message"; string-only); SM-VERIFY-FIX (05.10) โ StateManager.saveMemoryFile post-rename verify canonicalized through the msgpack round-trip (closes the E7 "separate decision"). Prior arcs: ABORT-CONTRACT close-out (04.10) at 63/930; CTX-FOOTER (02.10 top entry at that time) โ LLM-side context usage footer on string tool results + jest RC#4 mapper fix, canon then ; CONTAMINATION-FIX follow-up C (01.10) โ session-memory read guards across the remaining resume surfaces + Edit-C regression suite.
buildCheckpointSavedNotice() body reworded to truth-aligned telemetry phrasing (one-shot checkpoint-saved notice no longer calls the auto-written record a "session-memory snapshot"); canon unchanged 64 suites / 938 tests โ GATE RED round 1 (~16:5x, tsc) โ fixed same session โ GATE GREEN round 2 ~16:57 (owner-run)Context: the F1 one-shot notice (17.09 G-B fix, buildCheckpointSavedNotice() in src/promptPreprocessor.ts) surfaces to the model โ on the turn a pre-compression checkpoint was saved while a token-limit warning was live โ that "An automatic session-memory snapshot was savedโฆ". That wording is not what the record actually is: autoTracker.autoSaveSessionMemory() writes an AUTO-WRITTEN machine telemetry record (the same class THRESHOLD-MARKER WORDING, 05.10 ~17:3x, already re-voiced on its stored-record text as "Machine telemetry record (auto-written; not a manually saved session memory)") โ it is NOT a manually triggered save_session_summary checkpoint, and after the same turn's compression much of what it referred to has been replaced. Owner-approved scope (F1 micro-arc): BODY REWORD ONLY inside buildCheckpointSavedNotice() โ truth-aligned with the companion autoTracker record text; header fragment, pct/idPart interpolation and the acknowledge directive structure stay byte-identical (fixture-pinned). Deliberately untouched per approved scope: the ungated Step-9 DEBUG logs at L885/L890 (L890 is a forensic anchor, wording accurate; gating one of eight sibling DEBUG lines incoherent โ family-wide gate would be a separate P3 arc).
Changes:
Tests: NONE ADDED OR EDITED โ fixture recon at implementation time (assumption disproved): tests/promptPreprocessor.test.ts pins ONLY stable structural fragments of the notice (header + "one-shot notice โ not a prompt", pct formatting, checkpoint-id slot, the acknowledge directive), NOT the volatile body wording โ zero test edits needed for this rewording; house precedent = don't over-pin wording. Canon math: unchanged at 64 suites / 938 tests by construction (string literals cannot change suite/test counts) โ the GREEN round-2 run confirms it with zero drift, closing out the pending-item assumption from the arc handout that had anticipated fixture updates.
Verification: PRE-GATE statics this session: byte-level diff vs pre-F1 state (Changes above) = exactly L69/L70 inside one function; per-line backslash census + EOL/BOM metadata verified post-write (crlf/noBOM). GATE ROUND 1 RED (~16:5x, owner-run): npx tsc --noEmit โ exactly 2 errors, both at src/promptPreprocessor.ts:69 โ TS1127 "Invalid character" (col 113) + TS1434 "Unexpected keyword or identifier" (col 114). Root cause = the F1 edit itself emitted ONE line break as a literal two-char \n (0x5C 0x6E) outside any string literal (idPart +\n ' in place ofโฆ') instead of an actual CRLF โ parser saw a stray backslash at statement position. Byte census localized it precisely: exactly one such spot in the entire file (L69 carried two backslashes; the other, col 233 = compressed.\n', is the legitimate in-string escape), CRLF=1317 / lone LF/CR = 0 everywhere else. Fix (single-region replace, same session): deleted the literal \n + stray indent, collapsing L69 back to the baseline's single-physical-line layout with only the F1 wording differing; post-fix census clean (L69's sole remaining backslash = its in-string escape), rendered-output fragment check PASS on all stable fragments. GATE ROUND 2 GREEN (~16:57, owner-run): canonical = exactly โ zero drift vs the PLAN-REMOVAL canon; delta expectation was zero by construction and held (string literals cannot change suite/test counts). Live expectation: nothing observable until the owner's next dist rebuild + reload โ the running plugin still renders the OLD body ("session-memory snapshot was saved", which fired in-session at ~95.9% today); after rebuild, a checkpoint-saved-during-compression turn acknowledges a machine telemetry record instead of a "saved session memory".
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Both PLAN-REMOVAL design verdicts CLOSED on owner GO today ("leave as-is" / "Accepted, Go") and are NOT re-opened here; the running dist still carries the pre-F1 wording until the next rebuild.
remove_plan tool (dry-run preview default) for unfinished plans; canon 63/931 โ 64 suites / 938 tests โ GATE GREEN ~18:4x (tsc clean, lint "0 problems", 64 suites / 938 tests ALL PASSED in 23.1 s, owner-run)Context: this morning's plan-store audit (store-slim arc, top of session memory) found .session_context/.ai_toolbox_plans.json had accumulated 40 records โ only 3 genuinely open; the store was slimmed to 11 on owner GO ("remove Stale records") and then root-caused: the planning toolset contained NO removal operation at all and close-out checklists never carried plan-removal, so arcs ending at token walls left every terminal plan persisted forever. Owner standing rule (~18:09): the plan store is working state only โ completed plans MUST be removed at natural completion; provenance belongs in CHANGELOG/session summaries/memory facts (recorded as memory fact memory_1791216590566). This arc implements that lifecycle into the toolset itself โ root-cause fix rather than recurring manual hygiene.
Changes:
Tests: +1 suite / +7 tests. Canon math per house rule: pre-arc canon 63 suites / 931 (owner-GREEN ~17:4x) + the new suite = 64 suites / 938 tests; nothing else touched, zero drift. NOTE โ handoff miscount adjudicated: this arc's notes said "+6 tests / expect 937", but the suite on disk carries exactly seven it() blocks (verified by grep at close-out) โ the GREEN run at 64/938 is the fully accounted canon, not a drift; any doc quoting "937" for this arc would be wrong. Round-1 RED (~18:3x, owner-run): exactly 2 failures / 938 total, both cross-suite contamination through the PRE-EXISTING PlanStorageManager mirror/fallback seam (NOT a logic defect โ .bak diff proves this arc never touched it): under jest every save() mirrors to <rootDir>/src/.session_context/โฆ and every empty-dir load() falls back to that same file; the repo-store guard protects only the live <rootDir>/.session_context, so the src-mirror is unprotected test residue โ a convention cwdConsistency.test.ts already documents with its OWN afterAll cleanup, self-contained as long as no earlier suite polluted it. The new (earlier-running) suite's 7 creates leaked via the fallback into later suites' isolated dirs (leaked plan IDs all carry epoch timestamps inside that run window โ provenance). Fix = test-only: scrub the src-mirror at BOTH ends of the new suite (hermetic start + no cross-suite leak, order-independent). The live root store was never touched by jest (guard throws on its writes โ save()'s console.error spam in jest output is the proof), and post-gate it correctly holds 12 plans = the slimmed 11 + this arc's own working plan until step 8 closes.
Verification: pre-gate statics this session: self-audit diff vs .bak = exactly the 3 core regions; per-file EOL/BOM metadata verified post-write on all touched files (test file LF/noBOM, en/de CRLF preserved). OWNER GATES โ round 1 (~18:3x): tsc --noEmit clean + lint "0 problems", but tests RED at 64/938 with the two contamination failures above; root-caused + test-only fix applied same session. Round 2 GREEN (~18:4x, owner-run): npm test = exactly 64 suites / 938 tests ALL PASSED in 23.1 s (delta vs pre-arc canon accounted line-by-line per house rule; zero drift anywhere else), npx tsc --noEmit -p tsconfig.json clean, npm run lint "0 problems". Live expectation: a fully completed plan now vanishes from .ai_toolbox_plans.json the moment its final step flips done (the response still carries full stats); abandoned plans need an explicit confirm-gated removal; LM Studio will list remove_plan after the owner's next dist rebuild.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Open owner verdicts carried from the arc handout: (a) auto-removal ships with NO config toggle (policy read of his rule โ say GO or ask for an opt-in follow-up); (b) provenance trade-off accepted by design.
Context: the store-audit follow-up arc had landed Option A โ honest relabeling of the mid-loop threshold markers (the guardMidLoopThreshold() records that are token-telemetry-only, because SDK v1.5 exposes no mid-turn chat-push surface: ToolCallContext = status/warn/signal/callId only) from "proactive checkpoint / snapshot" to "threshold marker record". Owner review of the applied wording rejected its defensive tone โ wanted the direct phrasing ("75% threshold reached, notifying user"). This arc re-voices those strings in the owner's style with one accuracy qualifier retained: the notification lands on the NEXT user message (the checkAndGeneratePrompt() YES/NO flow), so "notifying user on next message" is stated rather than a bare "notifying user". The enrichment option was already reversed byte-identical from root .bak baselines before this arc; nothing here reopens it.
Changes:
Tests: none added โ string-only edits; no test logic or count moves. Test-coupling grep before handoff was clean: tests/fix20_midloop_token_counting.test.ts asserts on TAGS only (auto_checkpoint), and tests/restoreSessionContext.test.ts fixtures mirror the ORIGINAL template text (pre-Option-A) โ nothing pins current wording; title-prefix + tag-based collapse logic is untouched by construction.
Verification: pre-gate statics this session: self-audit file_diff vs the root pre-arc baseline = exactly those 4 lines inside the 3 regions, nothing else in a 36 KB file (the diff simultaneously documents the Option-Aโowner-wording consolidated delta over the shipped original); full read-back; EOL/BOM metadata post-write = crlf/noBOM preserved. GATE GREEN (~17:4x, owner-run): canonical npm test = exactly 63 suites / 931 tests ALL PASSED in 22.5 s โ zero drift vs the SM-VERIFY-FIX canon (no delta expected or observed; string literals cannot change suite/test counts). Canon-lineage note: the resume-time "930-vs-931" discrepancy is adjudicated CLOSED by this run โ yesterday's docs-sweep record of a verified 63/930 was a pre-SM-VERIFY-FIX snapshot, and all current-state docs (README L7/L48/L103, ARCHITECTURE.md tests comment, package.json description) already read 931 as of the top entry. Live expectation: nothing observable beyond the log lines + stored record text themselves; FSM, hysteresis, guard rollback and YES/NO prompt flow byte-identical.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in).
StateManager.saveMemoryFile post-rename verify canonicalizes own records through the msgpack round-trip (closes the E7 "separate decision" deferred in the 04.10 A-arc close-out); canon 63/930 โ 63 suites / 931 tests โ GATE GREEN ~16:5x (63 suites / 931 tests ALL PASSED, owner-run)Context: the 04.10 A-arc E7 close-out fixed exactly this bug class on the CSM side (E7-VERIFY-FIX canonicalization in saveCore) and explicitly deferred its StateManager-side twin as a "separate decision": same shared store, same verify design, same hazard โ any state value carrying one undefined-valued key (e.g., a summary-shaped record with pending_tasks: undefined) would false-positive the SM's own post-rename verify. This arc closes that deferral. Root cause (lib-level proof inherited from E7 and re-confirmed against this code path): @msgpack/msgpack encodes undefined as nil, which decode() returns as an explicit null, while JSON.stringify() DROPS undefined-valued keys entirely โ so the pre-fix strict compare of stringify(RAM value) vs stringify(decoded disk hit) mismatched on OUR OWN successful commit for any such record. Consequence chain (identical to E7, one layer over): false "Clobber detected" on EVERY attempt โ D-RACE bound exhaustion (3ร) + loud all-clobbered ERROR, and โ since ONLY the intact branch writes <filePath>.backup.json โ the last-known-good mirror stays stale/missing while the primary is correct. That mirror is exactly what loadMemoryFile's quarantine-recovery restores from, so every such save silently degraded recoverability.
Changes:
Tests: tests/stateManagerRace.test.ts +1 test, zero new files/suites โ new describe "SM-VERIFY-FIX" appended after the B3 block: a realistic summary-shaped value (the save_session_summary record class) carrying ONE undefined-valued key (pending_tasks: undefined โ the exact trap CSM's nodesToEntries() pinned on the context side) + an ordinary string control entry, saved through forceSave(). Asserts BOTH (1) disk durability in canonical wire form (undefined โ nil โ explicit null on decode) AND (2) THE regression pin: the .backup.json mirror EXISTS and carries both records โ written EXCLUSIVELY by the intact branch, so pre-fix its absence is the assertion that fails. The mirror rather than log output is the observable by design: under jest the SM logger no-ops (JEST_WORKER_ID / isTestEnvironment gate), making the durable side-effect the honest regression surface (E7's stale-mirror signature, one layer over).
Verification: pre-gate statics this session โ full read-back of both files; self-audit file_diff vs .bak = minimal scope confirmed for BOTH (src delta is strictly SM-VERIFY-FIX-class: the canonicalize block + its comment, nothing else in a 59 KB file; test delta is the single appended describe). GATE GREEN (owner-run ~16:5x): npx tsc --noEmit clean + canonical npm test = exactly 63 suites / 931 tests ALL PASSED in 22.58 s โ canon 63/930 (the ABORT-CONTRACT arc's GATE-4 closure, re-confirmed ~21:0x on 04.10) + 1 test in the existing stateManagerRace.test.ts, zero new suites, zero drift anywhere else; delta accounted line-by-line per house rule. Live expectation: a state value with an undefined-valued key now verifies INTACT against its own commit (mirror refreshed as usual), while genuine clobber/mangle detection is byte-for-byte unchanged โ the SM and CSM verify layers are now canonically aligned on one shared store.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in). With this entry both sides of the E7 bug class are closed: CSM saveCore (04.10 A-arc) and SM saveMemoryFile (this arc); canon is 63 suites / 931 tests.
ctx.signal wired into every long-running tool surface + contextGuard tiktoken fallback bounded; canon 61/917 โ 63 suites / 930 tests via two late-added abort-contract suites (see Tests) โ GATE 4 GREEN ~20:46 (63/930 ALL PASSED in ~22 s, owner-run)Context: owner GO: wire the host abort signal (ToolCallContext.signal) through all spawn/fetch surfaces so a user cancel or host timeout stops in-flight work instead of orphaning child processes and dangling fetches, plus item (c): bound the synchronous tiktoken encode paths in contextGuard. Zero happy-path change was an explicit constraint: no-signal calls must stay byte-identical (verified per file by diff audit below). The contract now covers: execution tools (child processes), HTTP client tools (fetch), web-research tools (fetch + needle/duck-duck-scrape), browser automation (puppeteer) โ the four surfaces with long-running external work.
Changes:
Tests: TWO NEW SUITES landed on disk ~19:28/~19:30 (AFTER the "NO new suites" close-out was written, inside this arc's session window โ author unattributed; suspected dual-writer from a parallel instance following the stale 18:55 plan note "then new jest suites + full gate"; owner ratified keeping both at ~19:57): tests/httpClientAbortContract.test.ts (+1 suite / +7 tests โ pre-aborted & mid-run abort envelopes on all three http tools, real Response() bodies through the production bounded reader, zero-change no-ctx guard) and tests/executionToolsAbortContract.test.ts (+1 suite / +6 tests โ zero-spawn pre-abort envelope + probe suppression for execute_command/run_javascript/run_tests, mid-run kill-before-close with fast settle, happy-path real-child guard). Canon delta exactly accounted per house rule: 61/917 โ 63 suites / 930 tests. FIRST OWNER GATE (~19:5x): 63 suites / 930 tests โ http suite 7/7 PASS (contract verified green on first run); execution suite 6/6 RED, every failure in beforeEach at jest.spyOn(cp, 'spawn') โ TypeError: Cannot redefine property: spawn โ TEST-SIDE ONLY defect (zero src impact; the other 924 tests all green incl. the canon-green existing executionTools.test.ts). ROOT CAUSE + FIX (test file only): under this repo's ts-jest CJS emit ( + ), TS compiles to , a wrapper object whose properties are NON-CONFIGURABLE getters, so jest-mock 30's spyOnโdefineProperty cannot land; and even had it patched, it would have patched the wrapper rather than the core-module exports object that reads via its named import ( call sites resolve live off the real module). Replaced with the house factory-mock pattern matching โ pass-through spawn recorder over ( plain : from inside a mock factory, of the SAME specifier re-enters the jest registry and re-invokes THIS factory โ infinite recursion; caught in second owner gate ~20:0x as at Runtime.requireModuleOrMock โ suite-level load failure, all six tests unrunnable, zero impact on the other 924), -prefixed bindings per jest-hoist rule, in-place array reset. THIRD OWNER GATE (~20:0x): suite LOADED and ran โ 4/6 PASS (registration + all three pre-abort zero-spawn envelopes); two failures, both in the real-child tests, BOTH test-side/environmental, src innocent: (a) mid-run test's blind 600 ms wait could fire before the node grandchild finished booting โ Windows silently misses a half-launched tree โ healthy child completes its natural exit and safeSpawn's close handler CORRECTLY refuses success for an already-aborted signal (the arc's own guarantee) โ flag absent; fixed with an event-driven gate that aborts only once a recorded ChildProcess exposes a real , plus a contract-aware assertion accepting EITHER the positive envelope OR the documented refusal โ never without an abort marker; (b) happy-path first launch captured on an exit-0 run (Windows console pipe flush under the jest worker); fixed with a 3-attempt union retry that fails loudly with diagnostics if all attempts come back empty. Fourth fix-3 note: the repair itself was re-audited after an intermediate edit injected a broken hunk โ full-file clean rewrite + byte-level read-back before handoff. Pre-gate statics done this session: full read-back of ; per-file diff audit vs = minimal scope confirmed for all five src files (each delta is strictly ABORT-CONTRACT-class; the one supporting type alias + header mirror in webResearch are documented necessities of TS2554 / dds options-replacement semantics). post-gate surfaced exactly ONE repo error โ : the pre-existing cast was NECESSARY while still called 3-arg directly against the 2-param bundled , but became a self-cast once this arc's edit switched that call to the alias (whose return types exactly) โ removed, type-erased only (zero runtime byte diff, tests untouched; the wikipedia cast from stays โ it changes types). + then both CLEAN. Caveat: this agent environment cannot run / (sandboxed, no shell; re-confirmed dead โ filesChecked 0), so type verification rides ts-jest inside the canonical gate.
Verification: First owner gate (~19:5x): 63 suites / 930 tests โ exactly the six new execution-suite failures (beforeEach throws, root-caused under Tests), everything else green. Second owner gate (~20:0x, after fix-1): suite failed to LOAD โ RangeError: Maximum call stack size exceeded in the mock factory (plain require('child_process') re-entered the registry and re-invoked itself; root-caused under Tests) โ all other 924 tests green. Third owner gate (~20:0x, after fix-2): suite loads and runs โ 928/930, only the two new real-child tests fail (root-caused under Tests; all other 930-scope tests green). GATE 4 PENDING (owner), after fix-3 (pid-event gate + contract-aware mid-run assertion + happy-path retry): canonical npm test โ expect 63 suites / 930 tests ALL PASSED (~25โ28 s, maxWorkers 1) with ts-jest clean; zero drift vs the other 924 passing was the pre-GATE-4 expectation (held through gates 1โ3 โ see Tests). GATE-4 CLOSURE (~20:15โ20:46, owner-run, FOUR iterations): attempt 1 again 928/930 โ root cause TEST-SIDE ONLY: fix-3 had used expect(value, 'custom message'), a two-argument form this jest build's expect() hard-rejects (Expect takes at most one argument.) โ both real-child tests threw BEFORE any behavior was exercised; fixed by single-arg expectations + conditional throws carrying the diagnostics (fix-4). Attempt 2 = 929/930: mid-run abort test PASSED for the first time on a live child (contract-aware assertion ran for real), happy-path still RED but its diagnostic throw sat after a bare so no evidence shipped (fix-5 reordered: throw-first with verbatim last-output). The then-remaining RED ( = BOTH pipes zero bytes on all 3 attempts, reproducible) turned out NOT to be an environment/pipe finding: TEMP probe v2 (later v3; deleted post-gate) proved the true root cause โ : corrupts grandchild argv whenever the line contains double quotes (ground truth: printed the literal text instead of evaluating to ; direct non-shell spawns with quoted args captured perfectly, isolating the cmd chain). Probe v3 measured every candidate on this machine: , , all BAD (), manual escaping = SyntaxError, . FIX (the arc's FIRST src change โ gates 1โ3 were test-side only): 's win32 branch now delegates to (POSIX byte-unchanged; all non-shell paths unchanged); accepted trade-off documented in-file โ the DEP0190-era deprecation warning may resurface on win32, strictly better than a broken quoting path. Final probe check GREEN through the src path, TEMP probe deleted before the canonical run. Live expectations: a cancelled turn's in-flight spawn/fetch/puppeteer work stops and its tool result carries the flag (never a false success for an aborted run); multi-MB message/system-prompt payloads hitting the tiktoken fallback cap log the โ ๏ธ line and return bounded+estimated instead of stalling the event loop; quoted shell commands now reach their target processes with quotes intact on Windows.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). src/promptPreprocessor.ts (CTX-FOOTER FIX#3, same day) is a SEPARATE arc โ see the 04.10 ~09:1x entry; its .bak reflects that edit, not this one. RE-CONFIRMATION (~21:0x, owner-run): canonical npm test re-ran at exactly 63/930 in ~22.5 s alongside the lint/typecheck clean pair above โ independent confirmation of the ~20:46 closure; residual tests/tmpCaptureProbe.test.ts.bak (deleted probe's backup, never jest-matched) removed in this close-out. NOTE (~19:58): the "NO new suites" statement in the original close-out was superseded by the two late-arriving abort-contract suites (see Tests) โ arc canon is 63/930, gate status per Verification; the docs sweep of stale 893/59 counts now also covers these, riding next publish prep.
Context: the A-arc's dual-writer regression (Suite E7 of tests/csmNonDestructiveSave.test.ts, pinned after the 03.10 wipe-class arc) went RED at its mirror assertion on the first owner gate: primary correct, mirror stale (SM-only content). Evidence chain from the gated runs: E7 failure showed primary [C,C,S,C] intact but mirror holding only the previous writer's records + clobberLog=true ร3, while Suite D interleaving passed โ pointing at CSM's OWN post-rename verify. Root cause, proven empirically with an in-project node probe against the real lib: @msgpack/msgpack has no representation for undefined and encodes undefined-valued properties as nil โ decode() returns them as explicit null, while JSON.stringify() DROPS undefined-valued keys entirely. CSM's verify compared each own entry's on-disk twin via strict JSON.stringify equality, so ANY entry carrying one undefined-valued key (ttl_ms: undefined in the production tier path nodesToEntries(), plus every non-session test fixture) mismatched its own successful commit โ 3ร false "Clobber detected" + D-RACE bound exhaustion on a perfectly healthy write, and โ since only the intact branch mirrors โ CSM's mirror stayed stale on every such save (the E7 failure).
Changes:
Tests: no new/changed test COUNTS โ Suite E (E1โE7) as gated; the TEMP diagnostic layer (tests/e7diag.test.ts + its .bak, plus the in-body E7DIAG/E7-CAPTURE instrumentation inside E7: SM _queueSave wrap, console.error trap, %TEMP%\e7diag-csm.txt dumps) was REMOVED in close-out after both gates GREEN โ E7's body is assertions-only again (writer order unchanged), with a one-line close-out comment noting where the evidence set lives.
Verification: OWNER GATES GREEN (~18:0x, owner-run): npx tsc --noEmit clean; targeted jest csmNonDestructiveSave.test.ts = 7/7, log verified for zero "Clobber detected" and E7 pass (its in-test assertions pin mirror = full 3-ctx + state union); targeted pair (csmNonDestructiveSave + csmSharedFileRegression) = 16/16 โ note: an earlier plan note said "expect 14"; the shared-file regression suite has grown since that count was written, zero โ is what mattered. Pre-cleanup full read-back of both fixed files byte-verified; self-audit file_diff vs .bak = minimal scope confirmed for BOTH files. PENDING (owner, post-cleanup): one re-gate to prove the instrumentation removal is neutral โ npx jest tests/csmNonDestructiveSave.test.ts tests/csmSharedFileRegression.test.ts --runInBand -i โ expect 16/16; and the canonical full npm test for this arc's expected canon 61 suites / 917 tests (verified base 59/905 from the 03.10 fail-loud second gate + FIX #3's new publishHardening.test.ts + Suite E ; NOTE: the ~09:1x entry header mis-stated its own canon as "59 suites / 910" โ off-by-one inherited here in pre-gate expectations, corrected at verification; was diagnostic-only and never counted in any verified canon, so its removal changes nothing; deltas must stay exactly accounted per house rule).
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in). This closes the E7 stale-mirror failure end-to-end: root cause pinned with lib-level proof, minimal fix on both layers, gates green, instrumentation removed.
setTurnEvaluation; expected canon 60 suites / 910 tests โ header initially mis-stated "59": off-by-one (same class as the 03.10 fail-loud entry's own 904โ905 correction; its Verification line "+1 suite = new file" + verified base 59/905 โ 60), corrected at verificationContext: closes the OPEN item carried by the top entry of the 03.10 fail-loud arc ("GO 2"): any throw between resetMidLoopDelta() (L713) and the single publish site TokenStatsManager.setTurnEvaluation(tokenCount, maxTokens) left turnBaselineTokens === 0 for the WHOLE tool loop of that turn โ mid-loop guard + every ctx_footer silently no-op (the 3.10 incident signature: absent footers at ~93โ95% real usage while executedTool kept appearing, zero [CTX-FOOTER] lines). The fail-loud entry made the suppression VISIBLE in the log; this entry removes the skip itself. Throw sites inside the Step 0.5 try (all verified against the exact source on 04.10): STEP 6 countTokens re-throw, STEP 9 auto-tracker re-throw, the whole compression block (prune pass / PART B checkpoint / compressHistory / history pop+append SDK mutations / post-compression recount), and the early return at "pullHistory() returned undefined".
Changes:
Tests: NEW hermetic suite tests/publishHardening.test.ts (+1 file / +5 tests): drives the REAL preprocess() end-to-end through fake controller/history/guard objects (type-only casts; no SDK runtime imports) with the real TokenStatsManager as ground truth โ this is precisely the class module-level unit gates cannot observe, because they pin TokenStatsManager directly instead of letting promptPreprocessor's own control flow run. Cases: (a) healthy turn publishes counted baseline + limit (pre-existing contract regression); (b) STEP 6 re-throw โ publish still runs with the safe 0/0 no-op state AND STEP 9 proven unreachable; (c) STEP 9 re-throw after a successful count โ the already-counted baseline is published (pre-fix: skipped entirely โ THE incident class); (d) compressHistory throw mid-compression branch โ pre-compression baseline published, history unmutated; (e) early return (pullHistory() โ null/undefined) โ finally still runs with 0/0, no stale/huge baseline leak. Hermeticity: RAG off, zero attachments, empty message array, real autoTracker singleton's two seams spied per test (checkAndGeneratePrompt, autoSaveSessionMemory) + restored in afterEach โ the tracker's FSM/storage never mutates; REPO-STORE GUARD untouched by construction (no fs writes at all).
Verification: EXPECTED canon 59 suites / 910 tests (+1 suite = new file, +5 tests; delta must be exactly accounted line-by-line per house rule), npm run typecheck + ESLint clean โ pre-gate statics DONE this session: full-program tsc (repo's own TS 5.9.3, 76 src files) 0 errors; targeted strict check of the new suite under tsconfig.test-equivalent options + @types/jest 0 errors in tests/; ESLint src/ 0 problems; read-back verified all three src edits byte-exact (CRLF preserved โ file-wide CRLFs intact, zero bare LFs introduced); canonical npm test executed 04.10 ~18:2x as the final combined owner gate = 61 suites / 917 tests ALL GREEN โ one run covering this entry's +1 suite/+5 AND A-arc Suite E (+7); counts verified, zero drift (see top entry). Live expectation: a turn whose preprocess() throws between reset and publish now republishes its real counted baseline (or a documented 0/0 when counting itself failed) instead of running the whole tool loop blind; healthy turns produce byte-identical behavior.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; footnote-level per the 03.10 ~14:32 standing mandate (git/commit = lowest priority, never before fixes + docs are 100% in). With this entry the entire CTX-FOOTER arc (footer mechanism โ option B surface widening โ fail-loud diagnosability โ publish hardening) is closed on the code side pending the owner gate.
Context: same-day follow-up to the option B entry above. Live observation ~12:4x (record ctx_1791025835710): after auto-checkpoint/compression, ctx_footer went absent on EVERY plain-object result of that turn (~93โ95% real usage) while executedTool stayed present โ with zero [CTX-FOOTER] log lines ever (owner console check ~13:0x). Root cause established by static analysis across the full pipeline (toolsProvider.ts wrapper + tokenStatsManager.ts + promptPreprocessor.ts preprocess() + contextGuard.ts): baseline/limit are module-level state, zeroed at the top of every preprocess() and republished at EXACTLY one site โ setTurnEvaluation() (L1023) inside one big try whose catch swallows everything; any throw between reset and publish leaves baseline === 0 for the whole tool loop โ the wrapper's baseline > 0 gate silently skips the footer on every result, while the executedTool stamp (no such gate) keeps appearing = the exact observed signature. Suspects ruled out by code reading: limit โค 0 (schema contextGuardTokenLimit min(1000), default 30k, constructor seed 262144 โ effectively never non-positive); toggle-off (would have killed the pre-compression footers too); swallowed exception (the only [CTX-FOOTER] warn line in src is the failure catch โ never fired). Design flaw exposed: suppression itself emitted NO log line at all โ the E-house-rule model-visible โบ logged invariant covered executedTool but not ctx_footer, which made this incident invisible for hours.
Changes:
src/toolsProvider.ts): module-level one-shot flag footerSuppressionNotified; live-baseline branch re-arms it on every wrapper pass; new else if warns exactly ONCE per suppression window: [AI Toolbox] [CTX-FOOTER] suppressed: turn baseline not published (preprocess() publish skipped or failed) .... Payloads byte-identical โ zero behavior change beyond this one log line.Tests: tests/contextUsageFooter.test.ts 29 โ 31 (+2, new nested describe "suppression visibility โ fail-loud warn"): (a) baseline-zero โ no ctx_footer + EXACTLY ONE suppression warn across two consecutive results in the same window, and footer returns on the very next result after publish (no sticky suppression); (b) re-arm semantics: a live-baseline pass followed by a reset-without-republish warns fresh. console.warn spied + filtered to [CTX-FOOTER] โฆ suppressed โ immune to other suite log noise.
Verification: EXPECTED canon 59 suites / 905 tests (874 โ 893 +10 option B โ +2 this entry; zero new files/suites), npm run typecheck + ESLint clean. FIRST OWNER GATE (~13:3x): typecheck + lint CLEAN; canonical npm test = 59 suites / 905 tests โ exactly the 2 NEW fail-loud tests RED, all other 903 green (count delta confirmed exact; note this entry's own header initially read 904 โ off-by-one in its arithmetic, corrected here). Root cause of the RED: test-side ONLY โ suppressWarns captured spy.mock.calls.filter(...) as a SNAPSHOT at beforeEach time, which is always [] before any tool call runs; fixed by holding a live spy reference filtered at assertion time (suppressedWarns() helper) in tests/contextUsageFooter.test.ts, zero src/ change. SECOND GATE GREEN (owner-run ~14:0x): canonical npm test = 59 suites / 905 tests ALL PASSED, zero drift; typecheck clean. Live expectation: any future publish-skip turn now names itself in the log instead of silent suppression; healthy turns produce no new output.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; manifest revision stays at 33; folds into the next Hub publish alongside the option B entry โ footnote-level per the 03.10 ~14:32 standing mandate, never before fixes + docs are 100% in. Note: this entry closes the DIAGNOSABILITY half of today's incident only; hardening the publish itself (Fix #3 โ catch-boundary restructure in promptPreprocessor.ts so compression-path throws cannot skip setTurnEvaluation) remains OPEN per owner decision "GO 2" โ see record ctx_1791025835710. RESOLVED by the top entry (04.10).
ctx_footer field on plain-object tool results; canon 59 suites / 903 tests (gate GREEN, owner-run ~14:0x โ the full 59/905 gate covers this entry's +10, see top entry)Context: the live verification of 03.10 (~11:3x, owner running the rebuilt plugin) proved the CTX-FOOTER mechanism correctly wired but UNOBSERVABLE on production results โ design gap, not a bug: the trigger gate required typeof result === 'string' while every registered ai_toolbox tool ends in an object envelope ({success, data|error}; full audit across src/tools + src/utils โ all 23 raw-string returns are inside helpers). Three options were presented (A accept-as-is ยท B additive ctx_footer field on plain-object results ยท C stringified-payload projection); the owner chose B: model-visible usage on every gated call, at ~10โ25 tok/call cost above the gate only.
Changes:
Tests: tests/contextUsageFooter.test.ts extended 19 โ 29 tests (+10: 2 string-form regression + 8 object-form gating matrix; same file, second top-level describe: "toolsProvider CTX-FOOTER wrapper integration"). Drives the REAL toolsProvider pipeline with one fake probe tool: the probe is registered via a suite-local jest.mock('./__mocks__/textProcessingTools.js') (+ same-string require() handle for per-test mockImplementationOnce) โ that request resolves, through the new per-file mapper entry above, to the SAME module ID toolsProvider's static import loads (tests/__mocks__/textProcessingTools.ts), so the factory replaces what the pipeline actually calls; other suites unaffected by construction. Coverage matrix: string form regression (exact append, exactly-once); object form at gate with byte-exact expected footer + coexisting executedTool stamp; below-gate silence; baseline-zero suppression; toggle-off; โฅ90% escalation clause in ctx_footer; no-clobber of tool-owned value; post-footer payload size recorded in the mid-loop delta (placement invariant); array/Date/number/null pass-through.
Verification: first owner re-gate (12:0x) RED โ 59 suites / 903 tests with exactly 1 failing suite: all 10 new wrapper-integration tests failed identically at expect(probe).toBeDefined() (every one of the 893 pre-existing tests stayed green) โ wiring defect, not footer logic (see "Jest wiring fix" bullet above; source read-back verified intact). Post-fix second re-gate GREEN (owner-run ~14:0x): full npm test = 59 suites / 905 tests all passed โ one gate covering option B (+10) AND the top entry's Fix #2 (+2); the single interim RED was this arc's own new-test spy-snapshot bug, fixed same session (top entry). EXPECTED canon 59 suites / 903 tests (+10 tests in the existing footer suite, zero new files/suites; delta = this file's 19 โ 29, nothing else touched โ must be exactly accounted), npm run typecheck + ESLint clean, LM Studio smoke: with a real chat above 50% window usage every tool result object now carries ctx_footer (was: none ever). Pre-gate static checks done this session: ctx_footer grep-verified collision-free across src/ + tests/ before introduction; read-back of both edited files verified.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; folds with the top entry when the owner runs it locally at their convenience (footnote-level per the 03.10 ~14:32 standing mandate โ lowest priority, never before fixes + docs are 100% in). Note: this entry closes the A/B/C arc opened by the 03.10 live check โ if B's re-gate surfaces any surprise, this entry is the reference for what changed and why.
Context: after the CC side-analysis of how context-compressor makes the LLM aware of token limits (CC is model-SILENT: only a pull-style get_context_usage handler, a post-hoc summary wrapper, and mid-task continuation nudges โ every warn/status block is user-only), the owner approved the ai_toolbox counterpart: push-style limit awareness. Owner design decisions 02.10: ON by default; footer appears once projected window usage crosses 50% (fixed module constant, deliberately NOT a config key) and then on every string tool result; format A [ctx ~48.3k/64k = 76%] (~10 tokens); near-limit escalation clause at โฅ90% (NEAR LIMIT - prefer small reads; wrap up if done). Below the gate turns pay zero footer tokens. Pre-gate blocker: the first full npm test after wiring failed with "Cannot find module './utils/contextUsageFooter.js' from 'src/toolsProvider.ts'" in 6 suites although the file existed on disk since ~16:18 โ root cause = the repo's documented RC#4 class (a .js-suffixed relative static import without a per-file moduleNameMapper entry; generic rules forbidden since G9 round-2 because they hijack node_modules internal requires such as @babel/types' require('../utils/shallowEqual.js')).
Changes:
Tests: NEW suite tests/contextUsageFooter.test.ts (17 cases): formatter table โ k-formatting, percent rounding, โฅ90% escalation clause present/absent at the boundary, suppression for limitโค0 / NaN / ยฑInfinity / negative usage / below-gate; + wrapper integration with a fake implementation asserting the footer is appended exactly once to gated string results while object results pass through byte-identical.

Remaining gate items confirmed clear at ~17:11 by owner ("all checks are clear"): npm run typecheck + ESLint clean; LM Studio agentic smoke with AI_TOOLBOX_DEBUG=1.

Edit-C covers the ONE remaining unguarded resume surface: the session-memory READ path inside executeProjectSwitch (Gap-2b) โ a stale/foreign store must degrade to self-describing output, never throw. Same-day companion arc (jest flag trap): an owner targeted re-run of 6 suites WITHOUT the V8 flag surfaced 3 NEW failures in tests/restoreSessionContext.test.ts ("A dynamic import callback was invoked without --experimental-vm-modules") although the same file had been green under npm test minutes earlier โ root cause proven: package.json scripts carry --experimental-vm-modules, plain npx jest invocations do not, and TS 5.9 (module=NodeNext + "type":"commonjs") keeps native dynamic imports untranspiled; repo precedent for the identical trap already existed (tests/fileSearch.test.ts:201).
Changes:
Tests: NEW hermetic suite tests/sessionMemoryReadGuards.test.ts (215 lines / 8 tests, zero .each()): A/B tmpdir working dirs per test; static imports ONLY โ deliberately flag-independent by construction. Pins: the eight read-guard cases incl. the Gap-2b regression (foreign/stale store on the executeProjectSwitch path degrades without throwing).

CHANGELOG_v3.md(rotated out on 01.10.2026 after the v3 file grew past a comfortable single-session read size (~67 KB / โ2 read chunks); same house pattern as the v1 โ v2 hand-off and the v2 โ v3 rotation of 20.09). At rotation, the ten newest v3 entries (the uncommitted rev-3x pile from FIX #33 through WALK-ABORT) were carried into this file verbatim; per owner order 01.10 (~21:xx), all of those pre-today entries have since been dumped back todocs/history/CHANGELOG_v3.md, where their bodies remain (the archive body was verified byte-identical before the dump โ rotation had left a duplicate copy, now deduped). This file now holds ONLY entries dated 01.10.2026 and later. New entries are added at the top of THIS file.
manifest.json revision advanced 0 โ 1 per the documented pure-rev-bump precedent, making the accumulated pile detectable for the pending Hub publish โ package.json version UNCHANGED (still v1.9.20); canon unchanged 74 suites / 1057 tests (manifest/docs-only entry โ zero code touched, gate trio not applicable)Context: since the rev-lock lift of 06.10 ~19:2x (package.json v1.9.18 โ v1.9.20 ยท manifest.json revision 33 โ 0), every entry carried "v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile)" โ local bytes moved continuously, but no Hub/GitHub publish ran since revision 30 (the last published to GitHub, 15.09). The owner order of today (~18:3x) is that long-pending publish GO, executed under the documented mechanic for making an update detectable: advance the manifest revision while the version stays fixed โ the same class as the v1.9.17-era pure rev-bumps (revs 29โ30โ31 so LM Studio detects the update) and the v1.9.16 bump (27โ28); the 06.10 unlock itself was a version move + revision reset, which this entry deliberately does NOT repeat.
Changes:
Scope boundary (explicit): this entry UNSTICKS the versioning state and documents it โ it does NOT itself perform a GitHub release / Hub push, dist rebuild or LM Studio reload; those remain owner-side steps exactly as in prior close-outs ("Remaining owner-side: dist rebuild + LM Studio reloadโฆ"). The pile now folding into that publish spans everything since 15.09 rev-30: FIX-35c ยท WALK-ABORT (in docs/history/CHANGELOG_v3.md after the 01.10 dump-back) ยท the 02.โ06.10 arcs (CTX-FOOTER โ i18n-CONFIRM / A3 / PLAN-SEAM, incl. the v1.9.20 rev-0 reset itself) ยท 05./07.10 PLAN-REMOVAL + the unlogged Arc-C sweep ยท 09.โ11.10 FIX #21 โ TOKEN-DIVERGENCE ยท 14.โ15.10 SESSION-MEMORY ARCS A/B/C (full 3-defect remediation closed owner-GREEN).
Versioning: this IS the versioning move โ revision 0 โ 1, first advance since the 06.10 reset; v1.9.20 rev-1 is now current state, sticky again only until the next explicit owner order (per the 21.09 standing rule: revisions change only on explicit instruction / Hub publish). Remaining carried items unchanged: restore-side hardening (candidate follow-up arc, needs fresh GO) ยท quarantine dir .pre-wipe-quarantine-20261014/ deletable only after a few confirmed-clean sessions ยท git footnote commit strictly last/opt-in.
Context: defect class C from the 14.10 forensics (recorded in the Arc-A top entry, deferred pending status verdict; owner ruling 14.10 ~18:15 DROPPED it as an open item and re-baselined it under this dedicated plan 15.10 โ scope locked to C1 + C2): two independent contamination paths into the session-memory pipeline. (C1) duplicate index rows โ SessionIndexManager.addEntry unconditionally prepended every write, so repeated persistence of one summary (e.g., tier-2 mid-loop save AND a PART-B close-out in the same turn) stacked byte-duplicate rows in .session_index.json, which restore re-surfaced N times. (C2) LLM-side artifacts leaking into persisted summaries โ generated continuation text carried __LM_STUDIO_INTERNAL_LSEP_* separator tokens, placeholder junk and reasoning preambles ahead of the real heading, round-tripping through future restores as if they were owner content. Design decisions fixed in-session: C1 overwrites IN PLACE within a bounded newest-row window (index stays chronological; constant + dated comment) instead of unbounded scan-dedupe; C2 strips at BOTH persist entry points โ before parse/persist/index, so the dirty text never touches disk on either path; C2a gates EMPTY-CONTENT runs (no meaningful user content in the toSummarize window โ skip generation entirely), mounted at the two Arc-C trigger sites only (contextGuard + promptPreprocessor) per the arc's step list.
Changes:
Tests: +1 suite / +6 tests: NEW tests/sessionIndexDedupe.test.ts โ pins the EXACT production guard expression (strict < WINDOW against disk arithmetic, not a paraphrase) across duplicate/no-duplicate/boundary shapes; expectations arithmetic-checked against the on-disk constant before handoff. The 16 in-file C2 strip+gate tests already written during the 14.10 handoff were carried UNGATED into this arc's first full gate โ they are part of the +22 delta, not new this session. Canon math per house rule: verified GREEN baseline 73/1035 (ARC-B owner re-gate 14.10 ~19:0x) + 16 ungated C2 tests + 6 new = EXPECTED 74 suites / 1057 tests โ the note "confirm 73/1035 unchanged" circulating in yesterday's pending items was arithmetically wrong about the C2 block and is hereby closed as such; do not repeat it. Zero other suites touched.
Verification: OWNER GATE GREEN (~18:2x, owner-run): full trio npx tsc --noEmit && npm run lint && npx jest โ tsc clean ยท full-src lint exit-0 ยท canonical npm test = exactly 74 suites / 1057 tests ALL PASSED in 21.3 s (preceded by the exact-match first pass at ~18:1x; delta vs pre-arc canon precisely +1 suite/+22, zero drift anywhere else โ the pre-existing 1035 confirm no regression). One lint observation closed as BY DESIGN: eslint flat-config ignores lists tests/, so a manually passed test file surfaces only an "ignored by pattern" warning (house lint scope is src-only via npm run lint = eslint src --ext .ts) โ zero errors either way, no config change required or made. Pre-gate statics: touched files parse-clean; in-sandbox tsc re-confirmed degraded (known limitation โ owner trio is the type gate); .bak baselines retained for all arc-touched files per house rule.

remove_plan), machine-tracked context entries accrued during its lifetime are retired, so a closed arc's pending items can never resurface as active in a future restore โ expected canon (+4 in-file; pre-arc 73/1031 per the Arc-A gate ~17:49) โ GATE GREEN ~19:0x (, owner-run re-gate; round-1 RED was this arc's own new test โ test-side baseline-capture defect, fixed same session): sandbox cannot execute tsc/jestContext: defect class B from the 14.10 forensics (recorded in the Arc-A top entry as deferred pending this arc): machine-written context entries that accrue during an arc's lifetime OUTLIVED their arcs โ auto-tracked gate decisions persisted scope:'global' with no close-out hook, so every session restore re-surfaced a finished arc's open items and they had to be deleted by hand (the 14.10 ~17:2x manual sweep is the incident instance). Owner GO "B" (~18:05) after Arc A went GREEN; design fixed in-session on two points: STRICT machine-entry predicate โ only entries that are tagged auto_track AND typed decision AND timestamped โฅ the closing plan's createdAt are ever eligible (explicitly recorded owner content has no machine tag and is NEVER auto-retired; pre-arc entries belong to earlier work), and best-effort wiring โ a context-store hiccup must never fail plan close-out itself.
Changes:
Tests: +4 tests in the EXISTING suite tests/taskPlanningTools.test.ts, new describe "supersede-on-close-out" (hermetic per house precedent โ isolated tmpdir working dir, REAL implementation via direct tool invocation): natural completion retires exactly the eligible machine entry while owner-decision and pre-arc entries survive on disk; remove_plan dry-run previews the count with a BYTE-IDENTICAL context store + plan file (pure-read proof); confirm removes plan + retires (survivor set pinned by id); zero-eligibility close-out performs ZERO writes (store byte-identical). Fixtures are REAL msgpack encoded through the production @msgpack/msgpack dependency (encode() import added to the suite) โ no mock stand-in for the storage format. Canon math per house rule: 73/1031 +4 in-file = 73 suites / 1035 tests (gate-verified ~19:0x โ see Verification).
Verification: GATE ROUND 1 (~19:0x, owner-run): canonical npm test = 73 suites / 1035 tests โ exactly ONE failure: the zero-eligibility byte-identity pin in this arc's own new describe (all other 1034 green incl. the three sibling FIX-B pins and the full pre-arc canon). Root cause TEST-SIDE ONLY, proven from source: the test captured its before baseline with fs.readFileSync(memPath) BEFORE its own eligibility rewrite (the deliberate re-seed that removes the only machine entry), so the byte-compare ran a 2-entry post-close-out store against a 3-entry pre-rewrite baseline โ guaranteed mismatch even though close-out performed zero writes (removeEntriesMatching short-circuits at matchedCount === 0 before any save; both production paths read-verified). Fixed same session: baseline capture moved BELOW the re-seed (one-line move + provenance comment); production code untouched. RE-GATE GREEN (~19:0x, owner-run): canonical npm test = exactly 73 suites / 1035 tests ALL PASSED in 20.8 s โ delta vs pre-arc canon (73/1031) is precisely the +4 in-file FIX-B describe, zero drift anywhere else; ESLint re-verified in-session post-fix = 0 errors / 0 warnings project-wide; npx tsc --noEmit confirmation still rides the owner trio (in-sandbox typecheck degrades to filesChecked=0 โ known limitation) โ risk assessed minimal: the only delta since round 1 is a one-line move inside an existing test, no new identifiers or types. Pre-gate statics done this session: ESLint via analyze_project = ; in-sandbox typecheck re-confirmed degraded (filesChecked=0 โ known limitation, owner tsc is the type gate); import soundness verified against live source ( + signature read-back); baselines retained for both touched files per house rule. Live expectation after the next dist rebuild: completing or removing an arc that accrued auto-tracked decisions logs exactly one line and future restores show no stale pending items from closed arcs; zero-eligibility close-outs are completely silent on disk (no store rewrite).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Remaining plan steps: C1 (index dedupe), C2 (empty-history gate + __LM_STUDIO_INTERNAL_LSEP_* artifact strip), restore-side hardening โ each its own gated arc.
Context: owner complaint ~17:08 that stale session memory resurfaced. Disk forensics over the quarantined pre-wipe store (memory-store-mirror-PREWIPE.json, 497 records) root-caused three defects: (A) all 401 context records scope:'global' with no TTL, 92% >7 days old โ pruneExpiredSessionEntries() had ZERO production callers (TTL enforced only on read paths), so machine checkpoints accumulated forever; family staleness flag measured newest-entry-only. (B) no supersede-on-close-out: closed arcs' pending lists resurfaced every restore; plans frozen at in_progress for days (deferred โ needs Arc-C status verdict first). (C) summary/index pipeline contamination + duplicate index writes (deferred, C1/C2). Owner GO full wipe ~17:15 โ store deleted, mirror QUARANTINED to .pre-wipe-quarantine-20261014/ (reversible; only recovery path until clean sessions confirm new behavior), post-wipe restore verified disk-clean. Arc discipline per house rule: one fix per gated arc โ this entry covers wipe + Fix A (+ the in-gate density restore below); Fixes B/C1/C2 follow their own gates.
Changes:
Tests: +1 suite / +5 tests total: NEW tests/contextLifecycleFixA.test.ts, 4 tests (hermetic, real tmp msgpack fixtures per house precedent): (1) inline reap of expired session-scoped entries on the next addEntry; (2) retention cap prunes oldest non-decision substantive entries beyond 100 with decision exemption even when a decision is the oldest entry; (3) checkpoint-tagged entries never count against the cap AND are TTL-reaped like any session entry; (4) fresh session-scoped entries pass through untouched. +1 in-file test in tests/autoTracker.test.ts ("FIX-A (14.10): checkpoint entries are written session-scopedโฆ") pinning the EXACT production input shape delivered to addEntry by autoSaveSessionMemory() (house rule โ LEVER-1 no-op lesson): records through an injected recording ctor (the suite's jest.mock factory is a plain class, not a jest.fn โ first gate RED was this test-side assumption; fixed same session), asserting one entry per save with scope:'session', tags:['auto_checkpoint','token_threshold'], type:'summary', id regex ^ctx_\d+_checkpoint$. Canon math: pre-arc canon 72 suites / 1026 (owner-GREEN 10.11 ~20:1x) + 1 suite/+4 + 1 in-file = 73 suites / 1031 tests; zero other suites touched.

Context: the live probe of 10.10 (verbatim 2,527-char session sample โ 787 prompt_tokens on qwen3.8-27b-ud at ~88% window fill โ 3.21 chars/token measured against this plugin's actual agentic mix: prose + JSON tool output + code + log) exposed that every consumer of estimateTokensFromChars() โ mid-loop deltas, the CTX-FOOTER projection and both tier gates โ was dividing by an UNMEASURED ร0.25 (+10% buffer) heuristic (4 chars/token assumed): dense payloads ran ~12โ18% hotter than every gate believed, silently shrinking the effective safety margin below the 75%/90%/95% rungs. Class B: the wire-shape credit โ per-locale schema byte estimates had no correction for locale-dependent description length (de/es/zh variants measure wider), so projection math over foreign-locale schemas mis-sized by a deterministic per-call amount. Both defects share one root shape: an estimated constant standing in for a measurable quantity (house precedent: Lever-1, 08.10).
Changes:
src/utils/tokenStatsManager.ts: NEW exported constant AGENTIC_CHARS_PER_TOKEN = 3.2 with provenance comment (probe sample size, model id, window fill %, date); the heuristic path now divides by this constant with ceil instead of ร0.25ร1.10 floor โ single source of truth for every estimation consumer (mid-loop delta via recordToolResult, CTX-FOOTER projection in the wrapper, tier-1/tier-2/compact trigger math). The precise tiktoken path is untouched: measured BPE still wins wherever it runs; only the fallback/estimation floor changed. No new config key (house stance โ a constant with provenance beats an unmeasured dial).Tests: ONE NEW hermetic suite pinning: the constant + its provenance comment, the ceil-division contract on exact boundaries (a one-char payload must never undercount below the probe floor), consumer wiring (mid-loop delta / projection consume the SAME divisor โ no second heuristic site may exist) and the locale-shape credit table incl. EN-zero. Canon math per house rule: pre-arc canon 71 suites / 1020 (owner-GREEN, 10.10 round 3) + this arc's one new suite with its six cases = 72 suites / 1026 tests โ zero other suites touched; the final GREEN run confirms it with zero drift anywhere else.
Verification: GATE ROUNDS (owner-run): pre-final rounds RED on three failures โ all test-side pins of this arc's new suite, root-caused and fixed same session (contemporaneous gate records ~20:0x); per-pin specifics not preserved in the durable record. The round at ~20:05 then ran GREEN for those three plus ONE additional failure in tests/stateManagerRace.test.ts B1 โ a suite this arc NEVER touched, green at ~19:58 โ assessed an intermittent race flake; passed on re-run before final. All fixes test-side only; src untouched between rounds. FINAL GATE GREEN (~20:1x): canonical npm test = exactly 72 suites / 1026 tests ALL PASSED ยท npx tsc --noEmit clean ยท lint "0 problems". Statics: edited files LF/noBOM verified per edit; constant + credit table grep-verified single-sourced (zero surviving ร0.25 heuristic sites in live src). Live expectation from the next dist rebuild onward: dense agentic turns project ~12โ18% hotter than pre-fix โ tier crossings and footer percentages read closer to real window fill; healthy turns shift identically in absolute terms, so no new early-fires are expected at the 75%/90%/95% rungs (the margins were under-sized before, not over-sized).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending; entry folds into the Hub publish with the rest of the pile, footnote-level per the standing mandate). Remaining owner-side: dist rebuild + LM Studio reload to ship live ยท git footnote commit strictly last/opt-in ยท docs sweep (this close-out) landed same pass: package.json description, all five READMEs (badge + meta line + comparison row + test-command comment), ARCHITECTURE tests/ canon comment, GLOSSARY status/canon rows + new "agentic density" entry.
Context: Root causes proven from source (09.10 verification session): (A) guardMidLoopThreshold armed NO state across turns โ "notified on next message" was only a console.log while the FSM re-evaluated usage fresh each turn, so any crossing followed by compression or a context-window increase dropped below threshold with zero user-visible mention (the owner never saw today's 75%+/92.2% checkpoints in chat); (B) between tier-2's @~90% forced SAVE and the model's 100% hard stop NOTHING ran mid-loop โ saves persist memory but never shrink context, and compressHistory() was reachable only at user messages โ run-away turns died at the wall twice in one day until the owner enlarged the window. Owner GO "A and B" (09.10 ~19:2x). Design decisions on record: 95% as FIXED constant, NOT a config key (house stance; deriving from compressionPercent would lose protection if the user sets schema max 100); two INDEPENDENT once-per-turn latches (@~90% save / @95% compaction โ neither suppresses the other; after a successful compression the republished baseline drops later projections under both gates anyway); compressMidLoop lives in contextGuard.ts to avoid widening the documented-safe promptPreprocessorโtoolsProvider cycle (grep-proven cycle-free); host-history swap duck-typed + non-fatal.
Changes:
Tests: NEW suite tests/fixA_midLoopNotice.test.ts, 6 tests (arms-on-success with usage-at-crossing + checkpoint-id pins, silent below threshold, failโretry arms exactly one notice, FSM-untouched contract, latest-crossing-replaces-not-stacks across the hysteresis floor, survives onContextCompressed() without swallowing an armed notice) and tests/tierB_midLoopCompaction.test.ts, 11 tests (fires-once at projected โฅ limitร95/100 with PART-parity opts + host-history swap + recount republish; INCLUSIVE exact boundary via the wrapper's own estimation math โ est(100 chars)=28, FOOTER_TOKEN_ESTIMATE=25 โ and silent one token below; 90โ95% band silence; once-per-turn idempotency; INDEPENDENCE from tier-2 (both fire in one โฅ95% pass); โค10-msg skip with latch hold same-turn; stub-guard-without-method silent skip while tier-2 on the SAME fake fires; rejection non-fatality; compressed:false โ no swap/no recount/deterministic log; strict-gate matrix) โ zero other suites touched. Both suites were written 09.10 (arc tail) but gated for the first time in this arc's rounds.
Verification: GATE ROUNDS (all owner-run): round 1 (~11:5x): tsc RED at src/toolsProvider.ts L588 โ TS2345 from Fix-B's as unknown[] downcast on the recount call (countTokens declares ContextMessage[]; the cast broke assignability). Fixed by REMOVING the cast (compressMidLoop's return already types outcome.messages) + in-file provenance comment; eslint 0/0 post-fix. Round 2 (~12:0x): tsc clean ยท lint clean ยท jest 71 suites / 1019โ1 โ sole failure in NEW suite fixA_midLoopNotice test-3 (retry.fired === false), root-caused as a HARNESS defect with production untouched (proven from source): the test called TokenStatsManager.resetMidLoopDelta() before its same-turn retry โ that hook is preprocess()'s NEW-TURN reset which by documented design zeroes baseline AND limit, so getTurnBaseline() read 0 and the retry evaluated at 12.3% usage < 75 threshold (below-threshold gate, never reaching hysteresis); production's save-failure rollback _midLoopGuardedAt โ 0 (autoTracker.ts L481โ483) is correct as-is โ its comment explicitly rejects the baselineTokensโ1 alternative. Fixed by deleting the line + a three-line production-shape comment; audit of the suite's other resetMidLoopDelta() use (test-5) confirmed safe (passes literal baselines, never reads state back). Statics: all touched files LF/noBOM verified per edit; project-wide eslint 0/0 after each fix. clean ยท lint "0 problems" ยท canonical = exactly โ zero drift elsewhere (the pre-existing 1003 confirm no regression). First LIVE Fix-A firing of the arc: owner confirmed YES to the tier-1 checkpoint at ~79% mid-close-out (~12:1x) โ the notice machinery under test exercised itself against this very conversation.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending). SHIPPED LIVE 10.10 ~13:1x โ owner dist rebuild (~13:08 local, dist/index.js mtime-verified) + LM Studio install/reload same day; both fixes verified present in the shipped bytes (Fix A notice literal @L56991 ยท 19 [TIER-2-COMPACT] telemetry lines incl. the wrapper โ
success line @L60885). Live-signal watch: one ๐ MID-LOOP CONTEXT THRESHOLD NOTICE ack on the next successful mid-loop crossing + exactly ONE [TIER-2-COMPACT] โ
Pre-emptive mid-loop compression complete per 95%-crossing turn ยท git footnote commit strictly last/opt-in. Plan plan_1791566441631_k9zi1jqqq closes with this entry + the zero-.bak sweep; provenance for the two gate-round fixes = memories of 10.10 (~11:5x cast, ~12:0x harness).
Context: tier-2's forced save existed only at user-message boundaries (PART B, promptPreprocessor), so inside a long tool loop it never fired and window usage could run past 100% before the next message โ nobody is listening mid-turn to answer tier-1's interactive prompt. Owner spec (supersedes the earlier 95%-key design; do NOT resurrect): reuse contextGuardCompressionPercent + contextGuardEnabled, no new config, SAVE ONLY with NO terminal-stop semantics. The wrapper already computed a shared CTX-footer projection per pass โ that became the trigger mount, so footer and tier-2 gate on one provably-identical "current usage" number with independent toggles (the pre-fix defect class was tier-2 nested UNDER the contextUsageFooter toggle: footer OFF silently disabled the save). SDK audit confirmed no plugin-side stop lever exists (@lmstudio/sdk d.ts: abortSignal/ToolCallContext.signal listen-only) โ consistent with spec.
Changes:
Tests: NEW suite tests/tier2MidLoopSave.test.ts, 13 tests / zero other suites touched โ canon 69 suites / 1003 tests. Pins: fires-once + persist of the keepLast slice (25 msgs โ generate gets exactly m0โฆm14); INCLUSIVE >= boundary at EXACTLY limit*percent/100 (exact-baseline construction vs the wrapper's own math) and silent one token below; once-per-turn idempotency across 3 results + re-arm on a NEW provider run (= new turn, 2 fires total); strict-gate matrix ([false, 0, undefined]) and percent-gate matrix (['90', 0, -10]) all silent at crossed threshold; save-failure non-fatality (persist {saved:false} โ result intact + โฅ1 [TIER-2] telemetry line); span-guard skip (12 msgs โ deterministic "nothing summarizable" log, LATCH holds when the list later grows to 30 same turn); null-list publish (?? [], no throw); footer-OFF independence; suppression-warn regression pin (warn exactly once per window, re-arm on live baseline).
Verification: GATE ROUNDS (all owner-run): round 1 (~16:4x): tsc RED at src/toolsProvider.ts โ the Step-4 lift-up had left an ORPHANED pre-#21 outer try/catch tail + one stray brace behind (the "re-nest" fix class; ground truth for the byte-equivalent suppression-warn re-expression = shipped original in dist/index.js L58537โ58577, read from disk since no git access). Fixed same session โ round 2 GREEN (tsc ยท lint 0 ยท canon unchanged 68/990; the two micro-fixes: redundant cast removal + jest RC#4 mapper entry above). Tier-2 went LIVE in production ahead of close-out (owner rebuild+reload ~17:2x, trigger ON) โ live signal = exactly ONE [AI Toolbox] [TIER-2] line per 90%-crossing turn. Round 5 (~17:5x): canon as pinned 69/1003 โ 3 failures, all in the NEW suite: F2 (โค10-past-keepLast fired generate([m0,m1]) โ root cause proven from failure output + code: guard turnMessages.length > 10 on a 12-msg list; correct predicate derived against ALL suite pins = fire iff (len โ keepLast) >= keepLast, INCLUSIVE at len=20 because tests 1/5/6/9 pin firing AT makeTurnMessages(20) โ naive variants would break passing tests); F1/F3 (result === undefined). Fix half-applied at session end (use-before-declaration intermediate state). Round 6 (~18:0x): tsc clean ยท lint 0 ยท jest 1001/1003 โ F2 GREEN after the completed span-guard fix; F1/F3 root-caused as a TEST-SIDE defect with no production involvement (evidence chain in forensics memory memory_1791562118870): both used โ verified against the installed jest 30 source ( L2161โL2247), that pattern never awaits the async function's promise, so the following assertion ran on an unassigned variable; exactly those TWO occurrences exist repo-wide (pattern-scan of all test files). Rewritten to direct + value pins = house style; zero other suites affected. clean ยท lint "0 problems" ยท canonical = exactly โ zero drift elsewhere (the pre-existing 990 confirm no regression). Statics: all edited files LF/noBOM verified; structural audit of the final wrapper block via corrected state-aware brace census = net-zero, anchor-verified (two earlier scanner passes false-alarmed on the single-line template @L433 โ pitfall recorded in memory).
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate). Plan plan_1791486516504_18lot11bd closes at step 8 (self-audit vs git baseline c1b4ca5 + zero-.bak sweep) on this GREEN gate. Remaining owner-side: dist rebuild + LM Studio reload to ship the corrected span-guard tier-2 (the ~17:2x live build predates it โ behaviorally near-identical in practice, but the shipped bytes should match the gated src; live verification after = exactly one [TIER-2] line per 90%-crossing turn; a short-list skip-log on a crossing with <20 published messages is expected telemetry, not a defect) ยท git footnote commit strictly last/opt-in.
minifyTool gains an _def.typeName === 'ZodObject' pre-check + one-node walk; canon 68 suites / 987 โ 990 tests (same suite file, +3 tests) โ GATE GREEN ~20:05 (tsc clean ยท lint "0 problems" ยท 990/990 ALL PASSED in 22.3 s, owner-run; wire harness ฮ = non-zero after two zero-delta rounds)Context: Lever-1's truncation pass shipped RED: the owner's first wire-harness re-run measured EXACTLY ZERO delta on 37,373 param chars (โฅ49 of 218 described fields were expected to lose bytes). Root cause proven with a file-level evidence chain (forensics memory memory_1791481751431): the SDK's tool() stores params as a LIVE root ZodObject (parametersSchema = z.object(rawShape), @lmstudio/sdk/dist/index.mjs ~L11353); v3 instances carry NO own .type/.properties, so the minifier's serialized-root branch can never match them and its per-entry fallback iterated the instance's ~29 ctor props without ever opening _def.shape() โ zero truncation. Jest was blind: 68 suites / 987 tests green with no test covering that exact input shape โ the lesson (tests must pin the EXACT production input shape, not just per-field/serialized forms) is now embodied in this arc's new tests, which caught a SECOND silent no-op one level down (see Verification round 1). Owner pick: Option A (minimal-scope pre-check; live-Zod constraint capping deliberately OUT of scope โ parked pending llama.cpp PR #17381 exposure audit + explicit GO).
Changes:
Tests: +3 tests in the EXISTING suite tests/toolsSchemaMinifier.test.ts (new describe "LIVE root ZodObject โฆ harness-zero-delta regression"): (1) end-to-end truncation through a live z.object(rawShape) passed as parametersSchema โ depth-1 fields (hard cut 83 / sentence-boundary cut 76), nested .optional() z.object field via _def.innerType, z.array(z.object()) element fields via _def.type, โค80-char describes byte-untouched, pass-through identity (minified.parametersSchema === schema) + validation accept/reject intact; (2) re-registration idempotency โ second pass over the SAME shared live schema is byte-stable; (3) guard negative space โ per-field shape records and serialized roots still route to their ORIGINAL branches (serialized-root maxLength 5000 โ 2000 cap proven to still land on the returned copy). Canon math: pre-arc canon 68 suites / 987 tests (owner-gate verified 08.10 round 2) + 3 in-file tests = 68 suites / 990 tests; zero new files/suites, nothing else touched. CANON LINEAGE NOTE: the DOC-PIN top entry below closed at 65/952 โ the intervening +3 suites / +35 tests belong to the Arc C sweep of 07.10, whose own changelog entry is NOT present in this file (gap flagged to owner at handoff; mtime 07.10 ~16:16 suggests an attempted write that never landed).
Verification: round-2 pre-gate statics (post-fix): full read-back of both files LF/noBOM; verbatim port of guard + walk executed in-sandbox against the repo's own zod 3.25.76 = 15/15 PASS, covering every jest assertion plus negative cases. GATE ROUNDS (all owner-run): round 1 (~19:58): build ESM+DTS green ยท npx tsc --noEmit clean ยท lint clean โ but 2/990 RED, both in this arc's new root-Zod tests: the first guard draft read INSTANCE .typeName (undefined on v3) โ silently fell back to the per-entry path again (failure #2's "Received Object" = plain-object reconstruction of the ~29 ctor entries โ direct proof). Fixed same session to _def.typeName. Round 2 (~20:03): canonical npm test = 68 suites / 990 tests ALL PASSED in 22.3 s โ both former REDs green, zero drift elsewhere (the pre-existing 987 confirm no regression). Wire harness (node scripts/wire_harness.cjs both, ~20:05): baseline โ current = tools 81 โ 81 ยท param chars 37,373 โ 36,047 (โ1,326 / โ3.55%) ยท desc chars 10,649 โ 10,649 UNCHANGED โ all savings concentrated in the target zone with tool-level truncation untouched, exactly per contract; parametersSchema key seen ร81 confirms the measured path is the real SDK one, and the non-zero delta empirically proves mutation surfaces through the host's serialization (a cloning host would have shown zero). The 1.3k figure matches the field distribution: only describes >80 chars lose bytes; many cut early at sentence boundaries; the 81โ89 tail sheds few chars each.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate). Close-out executed in-queue: arc .bak sweep done (src/toolsSchemaMinifier.ts.bak, tests/toolsSchemaMinifier.test.ts.bak removed; 12 PRE-EXISTING stale .bak files from earlier arcs left untouched โ flagged for owner decision, not swept unilaterally). Remaining owner-side items: dist rebuild + LM Studio reload to ship live (the harness already ran against the post-fix build) ยท git footnote commit strictly last/opt-in ยท Arc C 07.10 changelog-entry gap (see Canon lineage note) ยท parked: live-Zod capMaxLength/capItems blindness (wire still carries constraint values >2000, e.g. max_lines: 5000) behind PR #17381 audit + explicit owner GO.
Context: the TOOL-DOC-SYNC arc's root cause was structural โ nothing validates registry-vs-docs drift (tsc/lint/jest cover code+tests only) โ and its close-out deferred exactly this gate by explicit owner decision ("1"). Owner GO ~20:4x. Suite authored in a dual-writer session (this instance debugged it through 3 owner-run gates). Two defects root-caused between the first REDs and GREEN: (1) jest mapper RC#4 โ jest.config.cjs gained one per-file entry (attachmentManager, L172โ173); (2) T2's heading matcher bled into tail prose โ stripDecor() strips parens, so its paren-skip logic could never fire and File System L35's "(24 โ incl. โฆ folded in from Text Processing, 23.09 Q6)" admitted "text processing" โ 24 (the Data Visualization line was the separate adjudicated figure). Owner adjudication "a+a": (a) TOOLS_REFERENCE ยงData Visualization keeps its deliberate chart-only (1) โ test-side skip, no doc edit; (b) README L151's Data-Viz row gains backticked siblings markdown_preview + get_repeat_tool_advice (the R4/R5 inline path).
Changes:
Verification: pre-gate statics: byte-simulation of the final matcher over all 25 live ## headings = zero unexpected mismatches, incl. both flagged risks โ Context Management 22 declared == 22 pins; Backup & Restore (6 rows below) parses leading int 6 == 6. Per-file EOL/BOM verified post-write: test file pure LF/noBOM (unchanged by edits); README/jest.config per house baseline.

Live effect from now on: any tool shipped without a doc surface โ or any family whose declared count diverges from live code โ REDs this gate in npm test; the TOOL-DOC-SYNC / stale-bundle drift class gains its structural feedback loop.
Versioning: no bump โ v1.9.20 rev 0 sticky (owner publish pending); entry folds into the Hub publish with the rest of the pile (footnote-level per the standing mandate).

Canon counts (64 suites / 941) and version stamps (v1.9.20 / manifest rev 0) verified CURRENT in every live doc (README L7/L48/L103, ARCHITECTURE.md L127+L1138, DOCUMENTATION.md header, package.json description); historical entries (CHANGELOG_v4 bodies below the top line, docs/history/*, RELEASE_NOTES.md) untouched per house rule. Exactly ONE real stale cluster found โ and it was the remove_plan gap the owner then pressed on ("das tool existiert !!!!"): the tool shipped GREEN 05.10 (PLAN-REMOVAL arc; canon move 63/931 โ 64/938) and is live in production dist since today's ~18:2x rebuild, yet was absent from both tool-inventory docs โ TOOLS_REFERENCE.md (ยงTask Planning "(3)", overview row "Task Planning | 3", no tool row; update_plan_step row lacked the auto-removal behavior) and README.md family table ("๐ Task Planning | 3"). ROOT CAUSE (three links): (1) the PLAN-REMOVAL close-out's docs sweep covered ONLY its declared current-state canon lines (README L7/L48/L103, ARCHITECTURE L1138, package.json description); (2) tool-inventory doc updates were never a step in any arc's close-out checklist; (3) no feedback loop exists โ the owner gate trio (tsc / lint / npm test) validates code + tests only, so registry-vs-docs drift is structurally invisible to every gate. Same failure class as the 06.10 stale .lmstudio/ bundles: nothing verifies, it was documented "in passing".

Context: the AutoTracker threshold flow's YES/NO confirmation prompts (promptPreprocessor.normalizeConfirmationReply + the two project-switch banners + autoTracker.checkAndGeneratePrompt warning) hardcoded English option words with a legacy bilingual 'yes'/'ja' fallback โ inconsistent for owners running any of the four non-EN ๐ Language settings. Owner verdict A: DISPLAY in ONLY the configured language (never bilingual); ACCEPT replies in ALL shipped languages by design (a config=en user may still answer JA). The union is derived from the locale files at load, so a future locale extends acceptance automatically โ one source of truth. FSM logic untouched by construction.
Changes:
Tests: +3 tests / zero new suites: tests/cwdConsistency.test.ts +2 (all-language acceptance cases incl. Sร/็กฎ่ฎค/็ขบ่ช + negative case); tests/autoTracker.test.ts pinned-wording assertion updated ('Reply 'YES'' โ no longer 'YES'/'JA') + 1 new it (localized display, fresh tracker per case to defeat pending-warning caching). A repo sweep found the old wording only in .bak / stale-bundle artifacts (.lmstudio/dev.js, production.js) โ owner rebuilds dist; those are not live sources. Canon math: pre-arc canon 64/938 + 3 cases = 64 suites / 941 tests; nothing else touched.
Verification: pre-gate statics this session: ESLint src/ = 0 problems (in-sandbox; sandbox tsc degrades to filesChecked=0, so the real type gate rides the owner trio). GATE GREEN (~19:1x, owner-run): npm run lint no problems ยท npm run typecheck (tsc --noEmit) clean exit ยท canonical npm test = exactly 64 suites / 941 tests ALL PASSED in 24.37 s โ the expected +3 landed with zero drift anywhere else. Live expectation: nothing user-visible until the owner's next dist rebuild + LM Studio reload (.lmstudio/production.js still carries the pre-arc wording; running instance otherwise unaffected).
Versioning: rev lock LIFTED on owner decision 06.10 ~19:2x โ package.json v1.9.18 โ v1.9.20, manifest.json revision 33 โ 0; this arc is the first entry under v1.9.20 rev 0 (owner publish pending; rev 30 was the last published to GitHub, 15.09). Canon docs swept in the same pass: README meta line + comparison table + test-command comment โ 64/941 ยท package.json description โ "941 passing tests across 64 suites" ยท ARCHITECTURE.md version stamp (v1.9.20 / manifest rev 0) + tests/ canon comment (canon since i18n-CONFIRM, prior-canon chain completed with the 64/938 step). Plan plan_1791306127867_gygh8zb3r closed end-to-end on this close-out (auto-removal at natural completion).
Context: the A2/A3 CSM write-back arc (implementation + forensics done 04.10 โ save() opts / saveCore union / _isOutOfScopeForSave, explicit-wipe flags on clearAll + removeCrossProjectEntries, root cause pinned: load() scope-filter + save of loaded-list only wiped foreign-stamped ctx on every default save) was implemented and read-back-verified, but its verification gates were owner-run items the 04.10 session could not execute from sandbox (child_process statically blocked; in-process typecheck filesChecked=0). The plan had persisted at 2/6 with steps 3โ5 pending "RUN next session" โ an orphan relative to the later PLAN-REMOVAL + PLAN-SEAM arcs, which re-gated the full canon daily. Today (06.10 ~18:1x) the owner ran all three gates plus a lint belt-and-braces after the PLAN-SEAM close-out; this entry records that closure with verified counts only.
Verification: OWNER GATES GREEN (all 06.10 ~18:2x, owner-run): npx jest csmNonDestructiveSave = 7/7 passed in 0.62 s โ E1, the pre-fix-failing pin (foreign-stamped record wiped on default save), green; regression trio csmSharedFileRegression | stateManagerMemoryFile | restoreSessionContext = 2 suites / 21 tests ALL PASSED in 0.89 s โ A3 regresses none of the FIX #2/#23/D-RACE contracts; npx tsc --noEmit -p tsconfig.json = clean exit (0 errors); extra belt-and-braces npm run lint = "0 problems" (ESLint zero-finding exit). Statics this session: EOL/BOM census of the A3 file โ src/tools/contextManagementTools.ts pure CRLF / no BOM, mtime 04.10 ~15:54Z (untouched since implementation โ today's gates re-verified exactly the shipped bytes; full tree state per today's PLAN-SEAM gate ~18:0x = 64 suites / 938 tests ALL PASSED in 23.4 s).
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Plan plan_1791101285283_ojyfcs9fb closed end-to-end on this close-out (6/6 โ natural-completion auto-removal from .ai_toolbox_plans.json; provenance here + in session memory).
PlanStorageManager's plugin-root mirror + fallback second store removed โ the CURRENT working dir's .session_context/.ai_toolbox_plans.json is now the SINGLE plan store; all test-only scrub workarounds that existed solely because of it deleted; canon unchanged 64 suites / 938 tests โ GATE GREEN ~18:0x (tsc clean, lint "0 problems", 64/938 ALL PASSED in 23.4 s, owner-run)Context: the PLAN-REMOVAL arc's first gate round (05.10 ~18:3x) went RED on cross-suite contamination proven to run through a PRE-EXISTING PlanStorageManager seam, not the new code: under jest every save() mirrored to <rootDir>/src/.session_context/โฆ (pluginRootPath captured from __dirname; in built dist that resolves to the plugin root) and every empty-working-dir load() fell back to that same mirror file. The repo-store guard protects only the LIVE <rootDir>/.session_context, so the src-mirror was unprotected test residue โ self-contained as long as no earlier-running suite polluted it (the PLAN-REMOVAL suite's 7 creates leaked via the fallback into later suites' isolated dirs; cwdConsistency.test.ts documented the convention with its own afterAll cleanup). The arc close-out had carried this as the optional P3 follow-up "kill the seam at source โ needs GO". Owner GO: remove the second store entirely rather than guard it. Design decision recorded in-session: SINGLE-STORE semantics over dual-store+guards โ plans live exactly where CWD says; on a project switch an empty new working dir shows no plans (matches FIX #3's per-call resolution intent) and the cross-project/cross-suite leakage path is eliminated by construction, not policed.
Changes:
Tests: NONE ADDED OR REMOVED โ this arc removes workaround code ONLY; no assertions added or deleted, so 64 suites / 938 tests is the deliberate invariant and zero count change was the gate expectation. The two previously-leak-prone suites (taskPlanningTools, cwdConsistency) run hermetic by construction now: nothing can reach a foreign store because none exists outside the working dir.
Verification: pre-gate statics this session: per-file .bak baselines created first (house rule), each change diff-audited in-scope against its baseline; EOL/BOM verified post-write per file (byte census 06.10 ~18:1x: src/tools/taskPlanningTools.ts pure LF [CRLF=0 / lone-LF=503] + tests/taskPlanningTools.test.ts LF โ both noBOM; tests/cwdConsistency.test.ts CRLF + jest.global-teardown.js CRLF, noBOM); ripgrep sweep across src/ + tests/ clean of pluginRootPath / scrub symbols in live code (residual hits confined to the four .bak baselines themselves). GATE GREEN (~18:0x, owner-run): npx tsc --noEmit clean ยท npm run lint "0 problems" ยท canonical npm test = exactly 64 suites / 938 tests ALL PASSED in 23.4 s โ zero drift vs the F1/PLAN-REMOVAL canon, confirming the delta-zero expectation. Live note: dist/ + .lmstudio/production.js still carry the pre-seam (mirror) build until the owner's next rebuild+reinstall โ functionally harmless in production today (the mirror was a second write of identical content), but single-store behavior goes live only after that rebuild; decision parked with the owner.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). The PLAN-REMOVAL arc's optional P3 follow-up ("kill the seam at source") is hereby CLOSED end-to-end; both earlier design verdicts (auto-removal as-is, no toggle / provenance trade-off accepted) remain closed and are NOT re-opened here.
Newest arcs: i18n-CONFIRM (top entry, 06.10 ~19:1x) โ confirmation prompts display the configured ๐ language's option words; reply acceptance covers all shipped locales via a union derived from locale files (canon 64 suites / 938 โ 941 tests; first v1.9.20 rev-0 entry); A3 CLOSE-OUT (06.10 ~18:2x) โ the 04.10 CSM write-back arc's deferred owner gates ran GREEN (7/7 ยท regression trio 2 suites/21 tests ยท tsc clean ยท lint "0 problems"), plan auto-removed at 6/6; verification closure only, zero code change, canon unchanged 64 suites / 938 tests; PLAN-SEAM (06.10) โ PlanStorageManager's plugin-root mirror + fallback second store removed; the working dir's .session_context/.ai_toolbox_plans.json is now the single plan store and all test-only scrub workarounds deleted (seam removal only, canon unchanged 64 suites / 938 tests; SHIPPED โ dist rebuild ~18:15 local + LM Studio reinstall/reload same day, owner-verified running instance); F1 WORDING micro-arc (06.10) โ checkpoint-saved notice body reworded to truth-aligned telemetry phrasing (string-only, canon unchanged 64 suites / 938 tests); PLAN-REMOVAL (05.10) โ completed plans auto-removed from the working-state store at natural completion + explicit confirm-gated remove_plan tool for unfinished plans; root-cause fix of the 29-stale-plan accumulation, canon gate moved to 64 suites / 938 tests; THRESHOLD-MARKER WORDING (05.10) โ owner re-voicing of mid-loop threshold-marker logs + stored record text ("threshold reached โ user notified on next message"; string-only); SM-VERIFY-FIX (05.10) โ StateManager.saveMemoryFile post-rename verify canonicalized through the msgpack round-trip (closes the E7 "separate decision"). Prior arcs: ABORT-CONTRACT close-out (04.10) at 63/930; CTX-FOOTER (02.10 top entry at that time) โ LLM-side context usage footer on string tool results + jest RC#4 mapper fix, canon then ; CONTAMINATION-FIX follow-up C (01.10) โ session-memory read guards across the remaining resume surfaces + Edit-C regression suite.
buildCheckpointSavedNotice() body reworded to truth-aligned telemetry phrasing (one-shot checkpoint-saved notice no longer calls the auto-written record a "session-memory snapshot"); canon unchanged 64 suites / 938 tests โ GATE RED round 1 (~16:5x, tsc) โ fixed same session โ GATE GREEN round 2 ~16:57 (owner-run)Context: the F1 one-shot notice (17.09 G-B fix, buildCheckpointSavedNotice() in src/promptPreprocessor.ts) surfaces to the model โ on the turn a pre-compression checkpoint was saved while a token-limit warning was live โ that "An automatic session-memory snapshot was savedโฆ". That wording is not what the record actually is: autoTracker.autoSaveSessionMemory() writes an AUTO-WRITTEN machine telemetry record (the same class THRESHOLD-MARKER WORDING, 05.10 ~17:3x, already re-voiced on its stored-record text as "Machine telemetry record (auto-written; not a manually saved session memory)") โ it is NOT a manually triggered save_session_summary checkpoint, and after the same turn's compression much of what it referred to has been replaced. Owner-approved scope (F1 micro-arc): BODY REWORD ONLY inside buildCheckpointSavedNotice() โ truth-aligned with the companion autoTracker record text; header fragment, pct/idPart interpolation and the acknowledge directive structure stay byte-identical (fixture-pinned). Deliberately untouched per approved scope: the ungated Step-9 DEBUG logs at L885/L890 (L890 is a forensic anchor, wording accurate; gating one of eight sibling DEBUG lines incoherent โ family-wide gate would be a separate P3 arc).
Changes:
Tests: NONE ADDED OR EDITED โ fixture recon at implementation time (assumption disproved): tests/promptPreprocessor.test.ts pins ONLY stable structural fragments of the notice (header + "one-shot notice โ not a prompt", pct formatting, checkpoint-id slot, the acknowledge directive), NOT the volatile body wording โ zero test edits needed for this rewording; house precedent = don't over-pin wording. Canon math: unchanged at 64 suites / 938 tests by construction (string literals cannot change suite/test counts) โ the GREEN round-2 run confirms it with zero drift, closing out the pending-item assumption from the arc handout that had anticipated fixture updates.
Verification: PRE-GATE statics this session: byte-level diff vs pre-F1 state (Changes above) = exactly L69/L70 inside one function; per-line backslash census + EOL/BOM metadata verified post-write (crlf/noBOM). GATE ROUND 1 RED (~16:5x, owner-run): npx tsc --noEmit โ exactly 2 errors, both at src/promptPreprocessor.ts:69 โ TS1127 "Invalid character" (col 113) + TS1434 "Unexpected keyword or identifier" (col 114). Root cause = the F1 edit itself emitted ONE line break as a literal two-char \n (0x5C 0x6E) outside any string literal (idPart +\n ' in place ofโฆ') instead of an actual CRLF โ parser saw a stray backslash at statement position. Byte census localized it precisely: exactly one such spot in the entire file (L69 carried two backslashes; the other, col 233 = compressed.\n', is the legitimate in-string escape), CRLF=1317 / lone LF/CR = 0 everywhere else. Fix (single-region replace, same session): deleted the literal \n + stray indent, collapsing L69 back to the baseline's single-physical-line layout with only the F1 wording differing; post-fix census clean (L69's sole remaining backslash = its in-string escape), rendered-output fragment check PASS on all stable fragments. GATE ROUND 2 GREEN (~16:57, owner-run): canonical = exactly โ zero drift vs the PLAN-REMOVAL canon; delta expectation was zero by construction and held (string literals cannot change suite/test counts). Live expectation: nothing observable until the owner's next dist rebuild + reload โ the running plugin still renders the OLD body ("session-memory snapshot was saved", which fired in-session at ~95.9% today); after rebuild, a checkpoint-saved-during-compression turn acknowledges a machine telemetry record instead of a "saved session memory".
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Both PLAN-REMOVAL design verdicts CLOSED on owner GO today ("leave as-is" / "Accepted, Go") and are NOT re-opened here; the running dist still carries the pre-F1 wording until the next rebuild.
remove_plan tool (dry-run preview default) for unfinished plans; canon 63/931 โ 64 suites / 938 tests โ GATE GREEN ~18:4x (tsc clean, lint "0 problems", 64 suites / 938 tests ALL PASSED in 23.1 s, owner-run)Context: this morning's plan-store audit (store-slim arc, top of session memory) found .session_context/.ai_toolbox_plans.json had accumulated 40 records โ only 3 genuinely open; the store was slimmed to 11 on owner GO ("remove Stale records") and then root-caused: the planning toolset contained NO removal operation at all and close-out checklists never carried plan-removal, so arcs ending at token walls left every terminal plan persisted forever. Owner standing rule (~18:09): the plan store is working state only โ completed plans MUST be removed at natural completion; provenance belongs in CHANGELOG/session summaries/memory facts (recorded as memory fact memory_1791216590566). This arc implements that lifecycle into the toolset itself โ root-cause fix rather than recurring manual hygiene.
Changes:
Tests: +1 suite / +7 tests. Canon math per house rule: pre-arc canon 63 suites / 931 (owner-GREEN ~17:4x) + the new suite = 64 suites / 938 tests; nothing else touched, zero drift. NOTE โ handoff miscount adjudicated: this arc's notes said "+6 tests / expect 937", but the suite on disk carries exactly seven it() blocks (verified by grep at close-out) โ the GREEN run at 64/938 is the fully accounted canon, not a drift; any doc quoting "937" for this arc would be wrong. Round-1 RED (~18:3x, owner-run): exactly 2 failures / 938 total, both cross-suite contamination through the PRE-EXISTING PlanStorageManager mirror/fallback seam (NOT a logic defect โ .bak diff proves this arc never touched it): under jest every save() mirrors to <rootDir>/src/.session_context/โฆ and every empty-dir load() falls back to that same file; the repo-store guard protects only the live <rootDir>/.session_context, so the src-mirror is unprotected test residue โ a convention cwdConsistency.test.ts already documents with its OWN afterAll cleanup, self-contained as long as no earlier suite polluted it. The new (earlier-running) suite's 7 creates leaked via the fallback into later suites' isolated dirs (leaked plan IDs all carry epoch timestamps inside that run window โ provenance). Fix = test-only: scrub the src-mirror at BOTH ends of the new suite (hermetic start + no cross-suite leak, order-independent). The live root store was never touched by jest (guard throws on its writes โ save()'s console.error spam in jest output is the proof), and post-gate it correctly holds 12 plans = the slimmed 11 + this arc's own working plan until step 8 closes.
Verification: pre-gate statics this session: self-audit diff vs .bak = exactly the 3 core regions; per-file EOL/BOM metadata verified post-write on all touched files (test file LF/noBOM, en/de CRLF preserved). OWNER GATES โ round 1 (~18:3x): tsc --noEmit clean + lint "0 problems", but tests RED at 64/938 with the two contamination failures above; root-caused + test-only fix applied same session. Round 2 GREEN (~18:4x, owner-run): npm test = exactly 64 suites / 938 tests ALL PASSED in 23.1 s (delta vs pre-arc canon accounted line-by-line per house rule; zero drift anywhere else), npx tsc --noEmit -p tsconfig.json clean, npm run lint "0 problems". Live expectation: a fully completed plan now vanishes from .ai_toolbox_plans.json the moment its final step flips done (the response still carries full stats); abandoned plans need an explicit confirm-gated removal; LM Studio will list remove_plan after the owner's next dist rebuild.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). Open owner verdicts carried from the arc handout: (a) auto-removal ships with NO config toggle (policy read of his rule โ say GO or ask for an opt-in follow-up); (b) provenance trade-off accepted by design.
Context: the store-audit follow-up arc had landed Option A โ honest relabeling of the mid-loop threshold markers (the guardMidLoopThreshold() records that are token-telemetry-only, because SDK v1.5 exposes no mid-turn chat-push surface: ToolCallContext = status/warn/signal/callId only) from "proactive checkpoint / snapshot" to "threshold marker record". Owner review of the applied wording rejected its defensive tone โ wanted the direct phrasing ("75% threshold reached, notifying user"). This arc re-voices those strings in the owner's style with one accuracy qualifier retained: the notification lands on the NEXT user message (the checkAndGeneratePrompt() YES/NO flow), so "notifying user on next message" is stated rather than a bare "notifying user". The enrichment option was already reversed byte-identical from root .bak baselines before this arc; nothing here reopens it.
Changes:
Tests: none added โ string-only edits; no test logic or count moves. Test-coupling grep before handoff was clean: tests/fix20_midloop_token_counting.test.ts asserts on TAGS only (auto_checkpoint), and tests/restoreSessionContext.test.ts fixtures mirror the ORIGINAL template text (pre-Option-A) โ nothing pins current wording; title-prefix + tag-based collapse logic is untouched by construction.
Verification: pre-gate statics this session: self-audit file_diff vs the root pre-arc baseline = exactly those 4 lines inside the 3 regions, nothing else in a 36 KB file (the diff simultaneously documents the Option-Aโowner-wording consolidated delta over the shipped original); full read-back; EOL/BOM metadata post-write = crlf/noBOM preserved. GATE GREEN (~17:4x, owner-run): canonical npm test = exactly 63 suites / 931 tests ALL PASSED in 22.5 s โ zero drift vs the SM-VERIFY-FIX canon (no delta expected or observed; string literals cannot change suite/test counts). Canon-lineage note: the resume-time "930-vs-931" discrepancy is adjudicated CLOSED by this run โ yesterday's docs-sweep record of a verified 63/930 was a pre-SM-VERIFY-FIX snapshot, and all current-state docs (README L7/L48/L103, ARCHITECTURE.md tests comment, package.json description) already read 931 as of the top entry. Live expectation: nothing observable beyond the log lines + stored record text themselves; FSM, hysteresis, guard rollback and YES/NO prompt flow byte-identical.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in).
StateManager.saveMemoryFile post-rename verify canonicalizes own records through the msgpack round-trip (closes the E7 "separate decision" deferred in the 04.10 A-arc close-out); canon 63/930 โ 63 suites / 931 tests โ GATE GREEN ~16:5x (63 suites / 931 tests ALL PASSED, owner-run)Context: the 04.10 A-arc E7 close-out fixed exactly this bug class on the CSM side (E7-VERIFY-FIX canonicalization in saveCore) and explicitly deferred its StateManager-side twin as a "separate decision": same shared store, same verify design, same hazard โ any state value carrying one undefined-valued key (e.g., a summary-shaped record with pending_tasks: undefined) would false-positive the SM's own post-rename verify. This arc closes that deferral. Root cause (lib-level proof inherited from E7 and re-confirmed against this code path): @msgpack/msgpack encodes undefined as nil, which decode() returns as an explicit null, while JSON.stringify() DROPS undefined-valued keys entirely โ so the pre-fix strict compare of stringify(RAM value) vs stringify(decoded disk hit) mismatched on OUR OWN successful commit for any such record. Consequence chain (identical to E7, one layer over): false "Clobber detected" on EVERY attempt โ D-RACE bound exhaustion (3ร) + loud all-clobbered ERROR, and โ since ONLY the intact branch writes <filePath>.backup.json โ the last-known-good mirror stays stale/missing while the primary is correct. That mirror is exactly what loadMemoryFile's quarantine-recovery restores from, so every such save silently degraded recoverability.
Changes:
Tests: tests/stateManagerRace.test.ts +1 test, zero new files/suites โ new describe "SM-VERIFY-FIX" appended after the B3 block: a realistic summary-shaped value (the save_session_summary record class) carrying ONE undefined-valued key (pending_tasks: undefined โ the exact trap CSM's nodesToEntries() pinned on the context side) + an ordinary string control entry, saved through forceSave(). Asserts BOTH (1) disk durability in canonical wire form (undefined โ nil โ explicit null on decode) AND (2) THE regression pin: the .backup.json mirror EXISTS and carries both records โ written EXCLUSIVELY by the intact branch, so pre-fix its absence is the assertion that fails. The mirror rather than log output is the observable by design: under jest the SM logger no-ops (JEST_WORKER_ID / isTestEnvironment gate), making the durable side-effect the honest regression surface (E7's stale-mirror signature, one layer over).
Verification: pre-gate statics this session โ full read-back of both files; self-audit file_diff vs .bak = minimal scope confirmed for BOTH (src delta is strictly SM-VERIFY-FIX-class: the canonicalize block + its comment, nothing else in a 59 KB file; test delta is the single appended describe). GATE GREEN (owner-run ~16:5x): npx tsc --noEmit clean + canonical npm test = exactly 63 suites / 931 tests ALL PASSED in 22.58 s โ canon 63/930 (the ABORT-CONTRACT arc's GATE-4 closure, re-confirmed ~21:0x on 04.10) + 1 test in the existing stateManagerRace.test.ts, zero new suites, zero drift anywhere else; delta accounted line-by-line per house rule. Live expectation: a state value with an undefined-valued key now verifies INTACT against its own commit (mirror refreshed as usual), while genuine clobber/mangle detection is byte-for-byte unchanged โ the SM and CSM verify layers are now canonically aligned on one shared store.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in). With this entry both sides of the E7 bug class are closed: CSM saveCore (04.10 A-arc) and SM saveMemoryFile (this arc); canon is 63 suites / 931 tests.
ctx.signal wired into every long-running tool surface + contextGuard tiktoken fallback bounded; canon 61/917 โ 63 suites / 930 tests via two late-added abort-contract suites (see Tests) โ GATE 4 GREEN ~20:46 (63/930 ALL PASSED in ~22 s, owner-run)Context: owner GO: wire the host abort signal (ToolCallContext.signal) through all spawn/fetch surfaces so a user cancel or host timeout stops in-flight work instead of orphaning child processes and dangling fetches, plus item (c): bound the synchronous tiktoken encode paths in contextGuard. Zero happy-path change was an explicit constraint: no-signal calls must stay byte-identical (verified per file by diff audit below). The contract now covers: execution tools (child processes), HTTP client tools (fetch), web-research tools (fetch + needle/duck-duck-scrape), browser automation (puppeteer) โ the four surfaces with long-running external work.
Changes:
Tests: TWO NEW SUITES landed on disk ~19:28/~19:30 (AFTER the "NO new suites" close-out was written, inside this arc's session window โ author unattributed; suspected dual-writer from a parallel instance following the stale 18:55 plan note "then new jest suites + full gate"; owner ratified keeping both at ~19:57): tests/httpClientAbortContract.test.ts (+1 suite / +7 tests โ pre-aborted & mid-run abort envelopes on all three http tools, real Response() bodies through the production bounded reader, zero-change no-ctx guard) and tests/executionToolsAbortContract.test.ts (+1 suite / +6 tests โ zero-spawn pre-abort envelope + probe suppression for execute_command/run_javascript/run_tests, mid-run kill-before-close with fast settle, happy-path real-child guard). Canon delta exactly accounted per house rule: 61/917 โ 63 suites / 930 tests. FIRST OWNER GATE (~19:5x): 63 suites / 930 tests โ http suite 7/7 PASS (contract verified green on first run); execution suite 6/6 RED, every failure in beforeEach at jest.spyOn(cp, 'spawn') โ TypeError: Cannot redefine property: spawn โ TEST-SIDE ONLY defect (zero src impact; the other 924 tests all green incl. the canon-green existing executionTools.test.ts). ROOT CAUSE + FIX (test file only): under this repo's ts-jest CJS emit ( + ), TS compiles to , a wrapper object whose properties are NON-CONFIGURABLE getters, so jest-mock 30's spyOnโdefineProperty cannot land; and even had it patched, it would have patched the wrapper rather than the core-module exports object that reads via its named import ( call sites resolve live off the real module). Replaced with the house factory-mock pattern matching โ pass-through spawn recorder over ( plain : from inside a mock factory, of the SAME specifier re-enters the jest registry and re-invokes THIS factory โ infinite recursion; caught in second owner gate ~20:0x as at Runtime.requireModuleOrMock โ suite-level load failure, all six tests unrunnable, zero impact on the other 924), -prefixed bindings per jest-hoist rule, in-place array reset. THIRD OWNER GATE (~20:0x): suite LOADED and ran โ 4/6 PASS (registration + all three pre-abort zero-spawn envelopes); two failures, both in the real-child tests, BOTH test-side/environmental, src innocent: (a) mid-run test's blind 600 ms wait could fire before the node grandchild finished booting โ Windows silently misses a half-launched tree โ healthy child completes its natural exit and safeSpawn's close handler CORRECTLY refuses success for an already-aborted signal (the arc's own guarantee) โ flag absent; fixed with an event-driven gate that aborts only once a recorded ChildProcess exposes a real , plus a contract-aware assertion accepting EITHER the positive envelope OR the documented refusal โ never without an abort marker; (b) happy-path first launch captured on an exit-0 run (Windows console pipe flush under the jest worker); fixed with a 3-attempt union retry that fails loudly with diagnostics if all attempts come back empty. Fourth fix-3 note: the repair itself was re-audited after an intermediate edit injected a broken hunk โ full-file clean rewrite + byte-level read-back before handoff. Pre-gate statics done this session: full read-back of ; per-file diff audit vs = minimal scope confirmed for all five src files (each delta is strictly ABORT-CONTRACT-class; the one supporting type alias + header mirror in webResearch are documented necessities of TS2554 / dds options-replacement semantics). post-gate surfaced exactly ONE repo error โ : the pre-existing cast was NECESSARY while still called 3-arg directly against the 2-param bundled , but became a self-cast once this arc's edit switched that call to the alias (whose return types exactly) โ removed, type-erased only (zero runtime byte diff, tests untouched; the wikipedia cast from stays โ it changes types). + then both CLEAN. Caveat: this agent environment cannot run / (sandboxed, no shell; re-confirmed dead โ filesChecked 0), so type verification rides ts-jest inside the canonical gate.
Verification: First owner gate (~19:5x): 63 suites / 930 tests โ exactly the six new execution-suite failures (beforeEach throws, root-caused under Tests), everything else green. Second owner gate (~20:0x, after fix-1): suite failed to LOAD โ RangeError: Maximum call stack size exceeded in the mock factory (plain require('child_process') re-entered the registry and re-invoked itself; root-caused under Tests) โ all other 924 tests green. Third owner gate (~20:0x, after fix-2): suite loads and runs โ 928/930, only the two new real-child tests fail (root-caused under Tests; all other 930-scope tests green). GATE 4 PENDING (owner), after fix-3 (pid-event gate + contract-aware mid-run assertion + happy-path retry): canonical npm test โ expect 63 suites / 930 tests ALL PASSED (~25โ28 s, maxWorkers 1) with ts-jest clean; zero drift vs the other 924 passing was the pre-GATE-4 expectation (held through gates 1โ3 โ see Tests). GATE-4 CLOSURE (~20:15โ20:46, owner-run, FOUR iterations): attempt 1 again 928/930 โ root cause TEST-SIDE ONLY: fix-3 had used expect(value, 'custom message'), a two-argument form this jest build's expect() hard-rejects (Expect takes at most one argument.) โ both real-child tests threw BEFORE any behavior was exercised; fixed by single-arg expectations + conditional throws carrying the diagnostics (fix-4). Attempt 2 = 929/930: mid-run abort test PASSED for the first time on a live child (contract-aware assertion ran for real), happy-path still RED but its diagnostic throw sat after a bare so no evidence shipped (fix-5 reordered: throw-first with verbatim last-output). The then-remaining RED ( = BOTH pipes zero bytes on all 3 attempts, reproducible) turned out NOT to be an environment/pipe finding: TEMP probe v2 (later v3; deleted post-gate) proved the true root cause โ : corrupts grandchild argv whenever the line contains double quotes (ground truth: printed the literal text instead of evaluating to ; direct non-shell spawns with quoted args captured perfectly, isolating the cmd chain). Probe v3 measured every candidate on this machine: , , all BAD (), manual escaping = SyntaxError, . FIX (the arc's FIRST src change โ gates 1โ3 were test-side only): 's win32 branch now delegates to (POSIX byte-unchanged; all non-shell paths unchanged); accepted trade-off documented in-file โ the DEP0190-era deprecation warning may resurface on win32, strictly better than a broken quoting path. Final probe check GREEN through the src path, TEMP probe deleted before the canonical run. Live expectations: a cancelled turn's in-flight spawn/fetch/puppeteer work stops and its tool result carries the flag (never a false success for an aborted run); multi-MB message/system-prompt payloads hitting the tiktoken fallback cap log the โ ๏ธ line and return bounded+estimated instead of stalling the event loop; quoted shell commands now reach their target processes with quotes intact on Windows.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate). src/promptPreprocessor.ts (CTX-FOOTER FIX#3, same day) is a SEPARATE arc โ see the 04.10 ~09:1x entry; its .bak reflects that edit, not this one. RE-CONFIRMATION (~21:0x, owner-run): canonical npm test re-ran at exactly 63/930 in ~22.5 s alongside the lint/typecheck clean pair above โ independent confirmation of the ~20:46 closure; residual tests/tmpCaptureProbe.test.ts.bak (deleted probe's backup, never jest-matched) removed in this close-out. NOTE (~19:58): the "NO new suites" statement in the original close-out was superseded by the two late-arriving abort-contract suites (see Tests) โ arc canon is 63/930, gate status per Verification; the docs sweep of stale 893/59 counts now also covers these, riding next publish prep.
Context: the A-arc's dual-writer regression (Suite E7 of tests/csmNonDestructiveSave.test.ts, pinned after the 03.10 wipe-class arc) went RED at its mirror assertion on the first owner gate: primary correct, mirror stale (SM-only content). Evidence chain from the gated runs: E7 failure showed primary [C,C,S,C] intact but mirror holding only the previous writer's records + clobberLog=true ร3, while Suite D interleaving passed โ pointing at CSM's OWN post-rename verify. Root cause, proven empirically with an in-project node probe against the real lib: @msgpack/msgpack has no representation for undefined and encodes undefined-valued properties as nil โ decode() returns them as explicit null, while JSON.stringify() DROPS undefined-valued keys entirely. CSM's verify compared each own entry's on-disk twin via strict JSON.stringify equality, so ANY entry carrying one undefined-valued key (ttl_ms: undefined in the production tier path nodesToEntries(), plus every non-session test fixture) mismatched its own successful commit โ 3ร false "Clobber detected" + D-RACE bound exhaustion on a perfectly healthy write, and โ since only the intact branch mirrors โ CSM's mirror stayed stale on every such save (the E7 failure).
Changes:
Tests: no new/changed test COUNTS โ Suite E (E1โE7) as gated; the TEMP diagnostic layer (tests/e7diag.test.ts + its .bak, plus the in-body E7DIAG/E7-CAPTURE instrumentation inside E7: SM _queueSave wrap, console.error trap, %TEMP%\e7diag-csm.txt dumps) was REMOVED in close-out after both gates GREEN โ E7's body is assertions-only again (writer order unchanged), with a one-line close-out comment noting where the evidence set lives.
Verification: OWNER GATES GREEN (~18:0x, owner-run): npx tsc --noEmit clean; targeted jest csmNonDestructiveSave.test.ts = 7/7, log verified for zero "Clobber detected" and E7 pass (its in-test assertions pin mirror = full 3-ctx + state union); targeted pair (csmNonDestructiveSave + csmSharedFileRegression) = 16/16 โ note: an earlier plan note said "expect 14"; the shared-file regression suite has grown since that count was written, zero โ is what mattered. Pre-cleanup full read-back of both fixed files byte-verified; self-audit file_diff vs .bak = minimal scope confirmed for BOTH files. PENDING (owner, post-cleanup): one re-gate to prove the instrumentation removal is neutral โ npx jest tests/csmNonDestructiveSave.test.ts tests/csmSharedFileRegression.test.ts --runInBand -i โ expect 16/16; and the canonical full npm test for this arc's expected canon 61 suites / 917 tests (verified base 59/905 from the 03.10 fail-loud second gate + FIX #3's new publishHardening.test.ts + Suite E ; NOTE: the ~09:1x entry header mis-stated its own canon as "59 suites / 910" โ off-by-one inherited here in pre-gate expectations, corrected at verification; was diagnostic-only and never counted in any verified canon, so its removal changes nothing; deltas must stay exactly accounted per house rule).
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; entry folds into the next Hub publish with the rest of the rev-3x pile (footnote-level per the standing mandate โ lowest priority, never before fixes + docs are 100% in). This closes the E7 stale-mirror failure end-to-end: root cause pinned with lib-level proof, minimal fix on both layers, gates green, instrumentation removed.
setTurnEvaluation; expected canon 60 suites / 910 tests โ header initially mis-stated "59": off-by-one (same class as the 03.10 fail-loud entry's own 904โ905 correction; its Verification line "+1 suite = new file" + verified base 59/905 โ 60), corrected at verificationContext: closes the OPEN item carried by the top entry of the 03.10 fail-loud arc ("GO 2"): any throw between resetMidLoopDelta() (L713) and the single publish site TokenStatsManager.setTurnEvaluation(tokenCount, maxTokens) left turnBaselineTokens === 0 for the WHOLE tool loop of that turn โ mid-loop guard + every ctx_footer silently no-op (the 3.10 incident signature: absent footers at ~93โ95% real usage while executedTool kept appearing, zero [CTX-FOOTER] lines). The fail-loud entry made the suppression VISIBLE in the log; this entry removes the skip itself. Throw sites inside the Step 0.5 try (all verified against the exact source on 04.10): STEP 6 countTokens re-throw, STEP 9 auto-tracker re-throw, the whole compression block (prune pass / PART B checkpoint / compressHistory / history pop+append SDK mutations / post-compression recount), and the early return at "pullHistory() returned undefined".
Changes:
Tests: NEW hermetic suite tests/publishHardening.test.ts (+1 file / +5 tests): drives the REAL preprocess() end-to-end through fake controller/history/guard objects (type-only casts; no SDK runtime imports) with the real TokenStatsManager as ground truth โ this is precisely the class module-level unit gates cannot observe, because they pin TokenStatsManager directly instead of letting promptPreprocessor's own control flow run. Cases: (a) healthy turn publishes counted baseline + limit (pre-existing contract regression); (b) STEP 6 re-throw โ publish still runs with the safe 0/0 no-op state AND STEP 9 proven unreachable; (c) STEP 9 re-throw after a successful count โ the already-counted baseline is published (pre-fix: skipped entirely โ THE incident class); (d) compressHistory throw mid-compression branch โ pre-compression baseline published, history unmutated; (e) early return (pullHistory() โ null/undefined) โ finally still runs with 0/0, no stale/huge baseline leak. Hermeticity: RAG off, zero attachments, empty message array, real autoTracker singleton's two seams spied per test (checkAndGeneratePrompt, autoSaveSessionMemory) + restored in afterEach โ the tracker's FSM/storage never mutates; REPO-STORE GUARD untouched by construction (no fs writes at all).
Verification: EXPECTED canon 59 suites / 910 tests (+1 suite = new file, +5 tests; delta must be exactly accounted line-by-line per house rule), npm run typecheck + ESLint clean โ pre-gate statics DONE this session: full-program tsc (repo's own TS 5.9.3, 76 src files) 0 errors; targeted strict check of the new suite under tsconfig.test-equivalent options + @types/jest 0 errors in tests/; ESLint src/ 0 problems; read-back verified all three src edits byte-exact (CRLF preserved โ file-wide CRLFs intact, zero bare LFs introduced); canonical npm test executed 04.10 ~18:2x as the final combined owner gate = 61 suites / 917 tests ALL GREEN โ one run covering this entry's +1 suite/+5 AND A-arc Suite E (+7); counts verified, zero drift (see top entry). Live expectation: a turn whose preprocess() throws between reset and publish now republishes its real counted baseline (or a documented 0/0 when counting itself failed) instead of running the whole tool loop blind; healthy turns produce byte-identical behavior.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; footnote-level per the 03.10 ~14:32 standing mandate (git/commit = lowest priority, never before fixes + docs are 100% in). With this entry the entire CTX-FOOTER arc (footer mechanism โ option B surface widening โ fail-loud diagnosability โ publish hardening) is closed on the code side pending the owner gate.
Context: same-day follow-up to the option B entry above. Live observation ~12:4x (record ctx_1791025835710): after auto-checkpoint/compression, ctx_footer went absent on EVERY plain-object result of that turn (~93โ95% real usage) while executedTool stayed present โ with zero [CTX-FOOTER] log lines ever (owner console check ~13:0x). Root cause established by static analysis across the full pipeline (toolsProvider.ts wrapper + tokenStatsManager.ts + promptPreprocessor.ts preprocess() + contextGuard.ts): baseline/limit are module-level state, zeroed at the top of every preprocess() and republished at EXACTLY one site โ setTurnEvaluation() (L1023) inside one big try whose catch swallows everything; any throw between reset and publish leaves baseline === 0 for the whole tool loop โ the wrapper's baseline > 0 gate silently skips the footer on every result, while the executedTool stamp (no such gate) keeps appearing = the exact observed signature. Suspects ruled out by code reading: limit โค 0 (schema contextGuardTokenLimit min(1000), default 30k, constructor seed 262144 โ effectively never non-positive); toggle-off (would have killed the pre-compression footers too); swallowed exception (the only [CTX-FOOTER] warn line in src is the failure catch โ never fired). Design flaw exposed: suppression itself emitted NO log line at all โ the E-house-rule model-visible โบ logged invariant covered executedTool but not ctx_footer, which made this incident invisible for hours.
Changes:
src/toolsProvider.ts): module-level one-shot flag footerSuppressionNotified; live-baseline branch re-arms it on every wrapper pass; new else if warns exactly ONCE per suppression window: [AI Toolbox] [CTX-FOOTER] suppressed: turn baseline not published (preprocess() publish skipped or failed) .... Payloads byte-identical โ zero behavior change beyond this one log line.Tests: tests/contextUsageFooter.test.ts 29 โ 31 (+2, new nested describe "suppression visibility โ fail-loud warn"): (a) baseline-zero โ no ctx_footer + EXACTLY ONE suppression warn across two consecutive results in the same window, and footer returns on the very next result after publish (no sticky suppression); (b) re-arm semantics: a live-baseline pass followed by a reset-without-republish warns fresh. console.warn spied + filtered to [CTX-FOOTER] โฆ suppressed โ immune to other suite log noise.
Verification: EXPECTED canon 59 suites / 905 tests (874 โ 893 +10 option B โ +2 this entry; zero new files/suites), npm run typecheck + ESLint clean. FIRST OWNER GATE (~13:3x): typecheck + lint CLEAN; canonical npm test = 59 suites / 905 tests โ exactly the 2 NEW fail-loud tests RED, all other 903 green (count delta confirmed exact; note this entry's own header initially read 904 โ off-by-one in its arithmetic, corrected here). Root cause of the RED: test-side ONLY โ suppressWarns captured spy.mock.calls.filter(...) as a SNAPSHOT at beforeEach time, which is always [] before any tool call runs; fixed by holding a live spy reference filtered at assertion time (suppressedWarns() helper) in tests/contextUsageFooter.test.ts, zero src/ change. SECOND GATE GREEN (owner-run ~14:0x): canonical npm test = 59 suites / 905 tests ALL PASSED, zero drift; typecheck clean. Live expectation: any future publish-skip turn now names itself in the log instead of silent suppression; healthy turns produce no new output.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; manifest revision stays at 33; folds into the next Hub publish alongside the option B entry โ footnote-level per the 03.10 ~14:32 standing mandate, never before fixes + docs are 100% in. Note: this entry closes the DIAGNOSABILITY half of today's incident only; hardening the publish itself (Fix #3 โ catch-boundary restructure in promptPreprocessor.ts so compression-path throws cannot skip setTurnEvaluation) remains OPEN per owner decision "GO 2" โ see record ctx_1791025835710. RESOLVED by the top entry (04.10).
ctx_footer field on plain-object tool results; canon 59 suites / 903 tests (gate GREEN, owner-run ~14:0x โ the full 59/905 gate covers this entry's +10, see top entry)Context: the live verification of 03.10 (~11:3x, owner running the rebuilt plugin) proved the CTX-FOOTER mechanism correctly wired but UNOBSERVABLE on production results โ design gap, not a bug: the trigger gate required typeof result === 'string' while every registered ai_toolbox tool ends in an object envelope ({success, data|error}; full audit across src/tools + src/utils โ all 23 raw-string returns are inside helpers). Three options were presented (A accept-as-is ยท B additive ctx_footer field on plain-object results ยท C stringified-payload projection); the owner chose B: model-visible usage on every gated call, at ~10โ25 tok/call cost above the gate only.
Changes:
Tests: tests/contextUsageFooter.test.ts extended 19 โ 29 tests (+10: 2 string-form regression + 8 object-form gating matrix; same file, second top-level describe: "toolsProvider CTX-FOOTER wrapper integration"). Drives the REAL toolsProvider pipeline with one fake probe tool: the probe is registered via a suite-local jest.mock('./__mocks__/textProcessingTools.js') (+ same-string require() handle for per-test mockImplementationOnce) โ that request resolves, through the new per-file mapper entry above, to the SAME module ID toolsProvider's static import loads (tests/__mocks__/textProcessingTools.ts), so the factory replaces what the pipeline actually calls; other suites unaffected by construction. Coverage matrix: string form regression (exact append, exactly-once); object form at gate with byte-exact expected footer + coexisting executedTool stamp; below-gate silence; baseline-zero suppression; toggle-off; โฅ90% escalation clause in ctx_footer; no-clobber of tool-owned value; post-footer payload size recorded in the mid-loop delta (placement invariant); array/Date/number/null pass-through.
Verification: first owner re-gate (12:0x) RED โ 59 suites / 903 tests with exactly 1 failing suite: all 10 new wrapper-integration tests failed identically at expect(probe).toBeDefined() (every one of the 893 pre-existing tests stayed green) โ wiring defect, not footer logic (see "Jest wiring fix" bullet above; source read-back verified intact). Post-fix second re-gate GREEN (owner-run ~14:0x): full npm test = 59 suites / 905 tests all passed โ one gate covering option B (+10) AND the top entry's Fix #2 (+2); the single interim RED was this arc's own new-test spy-snapshot bug, fixed same session (top entry). EXPECTED canon 59 suites / 903 tests (+10 tests in the existing footer suite, zero new files/suites; delta = this file's 19 โ 29, nothing else touched โ must be exactly accounted), npm run typecheck + ESLint clean, LM Studio smoke: with a real chat above 50% window usage every tool result object now carries ctx_footer (was: none ever). Pre-gate static checks done this session: ctx_footer grep-verified collision-free across src/ + tests/ before introduction; read-back of both edited files verified.
Versioning: no bump โ v1.9.18 sticky per 21.09 owner decision; revision stays at 33; folds with the top entry when the owner runs it locally at their convenience (footnote-level per the 03.10 ~14:32 standing mandate โ lowest priority, never before fixes + docs are 100% in). Note: this entry closes the A/B/C arc opened by the 03.10 live check โ if B's re-gate surfaces any surprise, this entry is the reference for what changed and why.
Context: after the CC side-analysis of how context-compressor makes the LLM aware of token limits (CC is model-SILENT: only a pull-style get_context_usage handler, a post-hoc summary wrapper, and mid-task continuation nudges โ every warn/status block is user-only), the owner approved the ai_toolbox counterpart: push-style limit awareness. Owner design decisions 02.10: ON by default; footer appears once projected window usage crosses 50% (fixed module constant, deliberately NOT a config key) and then on every string tool result; format A [ctx ~48.3k/64k = 76%] (~10 tokens); near-limit escalation clause at โฅ90% (NEAR LIMIT - prefer small reads; wrap up if done). Below the gate turns pay zero footer tokens. Pre-gate blocker: the first full npm test after wiring failed with "Cannot find module './utils/contextUsageFooter.js' from 'src/toolsProvider.ts'" in 6 suites although the file existed on disk since ~16:18 โ root cause = the repo's documented RC#4 class (a .js-suffixed relative static import without a per-file moduleNameMapper entry; generic rules forbidden since G9 round-2 because they hijack node_modules internal requires such as @babel/types' require('../utils/shallowEqual.js')).
Changes:
Tests: NEW suite tests/contextUsageFooter.test.ts (17 cases): formatter table โ k-formatting, percent rounding, โฅ90% escalation clause present/absent at the boundary, suppression for limitโค0 / NaN / ยฑInfinity / negative usage / below-gate; + wrapper integration with a fake implementation asserting the footer is appended exactly once to gated string results while object results pass through byte-identical.
Verification: โ

Remaining gate items confirmed clear at ~17:11 by owner ("all checks are clear"): npm run typecheck + ESLint clean; LM Studio agentic smoke with AI_TOOLBOX_DEBUG=1.

executeProjectSwitch session-memory path + jest flag independence; canon gate 57/866 โ 58 suites / 874 testsContext: parts A/B of the CONTAMINATION-FIX arc (session-memory read guards on project-switch paths, Gap-1 class in src/tools/contextManagementTools.ts) had closed earlier today and were triple-verified: hermetic unit suites + full gate 57/866 owner-run twice (~17:52 and ~18:06 โ canon moved from 30.09's 56/860 by exactly +1 suite / +4 tests stateManagerRefreshProject + 2 B1/B2, zero unexplained drift). Edit-C covers the ONE remaining unguarded resume surface: the session-memory READ path inside executeProjectSwitch (Gap-2b) โ a stale/foreign store must degrade to self-describing output, never throw. Same-day companion arc (jest flag trap): an owner targeted re-run of 6 suites WITHOUT the V8 flag surfaced 3 NEW failures in tests/restoreSessionContext.test.ts ("A dynamic import callback was invoked without --experimental-vm-modules") although the same file had been green under npm test minutes earlier โ root cause proven: package.json scripts carry --experimental-vm-modules, plain npx jest invocations do not, and TS 5.9 (module=NodeNext + "type":"commonjs") keeps native dynamic imports untranspiled; repo precedent for the identical trap already existed (tests/fileSearch.test.ts:201).
Changes:
Tests: NEW hermetic suite tests/sessionMemoryReadGuards.test.ts (215 lines / 8 tests, zero .each()): A/B tmpdir working dirs per test; static imports ONLY โ deliberately flag-independent by construction. Pins: the eight read-guard cases incl. the Gap-2b regression (foreign/stale store on the executeProjectSwitch path degrades without throwing).

Two supporting pieces, both documented in-file: a DDGSearchCompat type alias because dds 2.2.7's bundled .d.ts declares only two params (TS2554) while runtime accepts three โ re-check on any dds bump; and a VERBATIM mirror of dds's internal COMMON_HEADERS, re-supplied ONLY when a host signal is present, because an options object REPLACES rather than extends dds's VQD defaults (without it the token hop would go out with Node's default UA โ less bot-resistant than the no-signal baseline). No-signal path stays byte-identical throughout.src/tools/browserAutomationTools.ts: browser_open_page, browser_session_control, preview_html, open_file take ctx; pre-launch gates prevent a cancelled call from launching Chrome or a system app, cooperative re-gates cover the slow-launch window (and between scripted actions โ click/type have no puppeteer signal, documented caveat), and the raw signal is forwarded where option types accept it natively (page.goto, waitForSelector). The singleton browser is deliberately NOT disposed on abort (same as every other error path). browser_session_close left unwired by design: near-synchronous dispose(), no spawn/fetch surface.src/contextGuard.ts: both synchronous tiktoken encode paths are now bounded at TIKTOKEN_SYNC_ENCODE_CHAR_CAP = 100_000 chars (per message/system prompt): precise BPE up to the cap, overflow estimated with the SAME ratio as the primary heuristic path (chars ร 0.25 ร 1.10) โ so an oversized payload cannot both block the host event loop AND under-count into delayed compression. โค cap โ byte-identical results (typical chat/file-paste messages never reach it).

Entire block try/catch: failure warns [CTX-FOOTER], never throws into the tool call; suppressed entirely when turnBaseline === 0.src/config.ts): contextUsageFooter bool key (zod schema + default true) through the toolsProvider config object, same pattern as compaction*; footer text is an English constant (data, not UI copy โ locales untouched).jest.config.cjs L164โ165): per-file entry '^\./utils/contextUsageFooter\.js$' โ '<rootDir>/src/utils/contextUsageFooter.ts' (single-dot form; ripgrep verified toolsProvider.ts:51 is the unique emitter; G9 round-2 rule honored โ no generic rule). Byte-verified per repo convention via require+RegExp against 4 specifiers (positive single-dot, negative two-dot / node_modules-style / sibling) + file_diff vs backup = exactly 2 added lines.src/tools/contextManagementTools.ts โ read-guard on the project-switch session-memory path (Gap-2b); no behavior change beyond the guarded degradation contract.jest.config.cjs): per-file moduleNameMapper keys for the Edit-C suite's static imports (RC#4 class โ first-match-wins ordering before the tools-mock fallback).tests/restoreSessionContext.test.ts, test file only): all three native await import('@msgpack/msgpack') sites replaced with CJS require() (+ typeof cast) โ verified @msgpack/msgpack@3.1.3 is dual-format (main = dist.cjs), so require() works under plain Node and jest with OR without the flag. Repo-wide scan: zero other native dynamic-import call sites in any of the 57 test files.src/promptPreprocessor.ts L536, Edit-C region): 2ร @typescript-eslint/no-unnecessary-type-assertion โ redundant as string casts after a typeof guard in extractLatestSessionSummary; casts removed + explanatory comment (byte-exact what eslint --fix would emit; no other reformatting).
