Session Ledger — 2026-07-07

Returns

• 2026-07-07T12:22 — Caught frame-inheritance before mutating the memory substrate (§3 trust-prior-pass-frame). The ratified upgrade plan assumes mempalace installed via pipx/uv → a clean 3.3.6→3.4.0 bump. Verified against the actual install: it is an editable git fork (~/_Dev/mempalace/.venv) on branch local/bge-m3-on-3.3.6, ahead 5 / behind 300 of origin/main. The 5 local commits are load-bearing: custom bge-m3 embedder (2 commits), the layers.py recency fix the wake glance depends on, and hallways.py pagination for the 71k-drawer wing_api. Upstream 3.4.1 (#1483) moved the default embedder to embeddinggemma and warns switching models on an existing palace requires full re-embed / else EF-identity mismatch → silent bad recall. Merging 300 commits onto the bge-m3 fork is NOT a version bump; treating it as one would be the exact contamination shape. HELD; surfaced to steward. The morning HNSW quarantine self-healed and #1665 root cause is still open even in 3.4/3.5 — so the upgrade does not cure what bit today.

Open horizons

• 2026-07-07T12:16 — Pulling thread (inherited): finish REVIEWED-49 folding. Next link = A4 + B(iii) as one small FIX (own PENDING/REVIEWED, v2.0.x patch). Then A1 Agent/Nomen registry (read retrieve.py hot path first). Then the steward-sequenced verification-architecture [PROPOSAL] + model-plurality note.
• 2026-07-07T12:16 — MemPalace: HNSW drift quarantine fired live during wake (#1665/#1589 class); installed 3.3.6 vs origin/main 3.5.0 (two minor bumps of relevant fixes ahead). Hold-and-plan; steward's call — not a wake action.
• 2026-07-07T12:16 — Skill-harvest open: promote completion-is-a-tripwire → Symmetria §3 flag (fresh); standing AUTHORIZED-not-built bmf-diagnose / mempalace-diagnose / /pre-build-audit.

MemPalace decision (in progress)

• 2026-07-07 — Steward leans LETTING GO of MemPalace; wants (a) a ~10-session evidence audit to feel settled, (b) confirmation the KG (highest-value aspect) can be recreated file-native.
• KG SECURED (no-regret move, done): exported 329 triples + 437 entities → memory/knowledge-graph.jsonl + knowledge-graph-entities.jsonl, all lines JSON-validated. KG is small/structured (84 drift-patterns = the gem; entities all type 'unknown' → the "entity-first" feature was never populated). Files-layer is git-tracked (dotfiles, 368 files) + dual-remote → the export is now MORE durable than the MemPalace KG. Recreation-as-file = an upgrade, not a compromise; aligns with the standing /wrap-up §5 proposal. Remaining wiring (wake reads it / wrap appends) is a small follow-on IF we wind down.
• Value read (mine, this session as evidence): files carried the entire wake reconstruction; MemPalace search/KG was confirmatory. Highest genuine value = KG drift-patterns (now file-secured) + the separate typography palace (keep, untouched).
• PENDING the independent audit before finalizing wind-down.

Confidence to recalibrate

• 2026-07-07T15:50 — Overclaimed "self-healed" re: the morning HNSW quarantine. It was damage-control, not repair — verified 108 quarantines since May 26 (near-daily, same segment UUID recurring). Corrected to the steward; the accurate frame is chronic compounding drift. Data itself is intact (sqlite 88,159 embeddings = 88,159 metadata; KG separate + present). Lesson: don't reach for a reassuring verb ("healed") before verifying the mechanism.

Authorization moves

• 2026-07-07T15:52 — Steward AUTHORIZED "Rebuild now" (in-version index rebuild via repair --mode from-sqlite, bge-m3 preserved). Decoupled from the version upgrade (deferred — doesn't cure #1665 root cause). Crosses the standing "don't run repair (#1589)" rule — safe because from-sqlite never opens a chromadb client on the corrupt index (dodges the SIGSEGV); executed with full verified backup + build-into-new-dir + manual verified swap.
• 2026-07-07T15:52 — Caught a second silent-loss trap before running (diagnose-before-fix). rebuild_from_sqlite (repair.py:1050+) rebuilds ONLY the chroma collections into a fresh dir; it never carries knowledge_graph.sqlite3. A bare in-place --archive-existing rebuild would have left the LIVE palace with the vector index but NO KG/diary/entity-graph (recoverable only from the archive). Mitigation: build from the frozen backup into a new dir, copy the KG in, verify, then swap — live palace stays whole until the last step.

Sub-agent dialogues

• 2026-07-07 — Independent MemPalace-value audit (general-purpose, neutral anti-confirmation prompt). VERDICT: search+KG NOT load-bearing for palace-memory — confirmatory/redundant. Evidence (3 convergent tests): (a) 27/31 kg_query = byte-identical wake ritual; only 4 task-directed; find_tunnels/traverse called 0× ever; genuine reach ~0.43/session, declining to ~0.07 in July; (b) grep test — 5/5 distinctive search payloads found verbatim in the Markdown files; ZERO transcript statements credit search/KG with surfacing file-absent content; (c) write:read ≈ 7:1 (217 kg_add vs ~32 reads); 437 entities all type 'unknown'. Heaviest use (06-30 clasp) returned a STALE claim the files corrected — anti-load-bearing. Confidence: counts 0.93, verdict 0.82. Honest caveat: semantic-convenience (would-I-have-grepped-it) unmeasured, but 0 sampled instances crossed the bar. Carve-outs preserved: drift-patterns (exported ✓), typography palace (separate, keep). Symmetria audit-agent check PASSED — calibration honest, flagged own confirmation-order risk, scope correct.
• DECISION (steward's, evidenced): wind down palace-memory MemPalace. Recommend executing the skill-rewrites FRESH, not at the end of this long session.
