# 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.
- 2026-07-07T18:05 — **A4-error avoided on my own draft (verify-against-primary-source).** My first A4+B(iii) draft repeated the frontier brief's shorthand — 'Principle 4 does not license scoping to one named community.' Steward said verify-now; fetched the primary Santa Barbara Statement. Principle 4 verbatim: 'Collections as data designed for everyone serve no one. Specific needs inform collections as data development' — it DOES concern designing for specific communities. The brief's shorthand was imprecise; the true distinction is audience-design (Principle 4) ≠ epistemic scope-warrant (A2). Corrected the draft to state the distinction. Principle 8 confirmed verbatim, kept. This is the Ninety-Ninety / completion-is-a-tripwire shape: the fluent first draft *felt* done; the citation was exactly where it would have been faked. The steward's 'verify now' call was the guard.

## 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.
- 2026-07-07T17:47 — **Post-/clear re-wake (Symmetria re-init).** Same day, ~15 min after wrap. Wake ran WITHOUT the §2.b MemPalace 5-step protocol — deliberate: yesterday's evidenced decision winds down `palace-memory`; leaning on it now would contradict the decision. Thread CONFIRMED = chamber-library REVIEWED-49 folding; git verifies A2 preamble + Olson (`34c39f1`) landed → A4 genuinely unblocked. Held open (steward's call): (a) still A4+B(iii) or a different chamber piece? (b) MemPalace decommission + BMF report before/after/separate-slot? Named the drift: `/wake-up` + `/wrap-up` are themselves on the decommission's "rewire to files" list (STAGED PLAN item 3) — parked, not silent.
- 2026-07-07T18:50 — **A1 hot-path question ANSWERED from the code (PENDING-49 executor-owed, closed).** Read `studium-engine/engine/retrieve.py` in full + surveyed `corpus/manifest.yaml` fields. **Decisive: the retrieval hot path performs ZERO agent/author accesses** — identity axes are `source_id`→`work` (title string) + `voice`; citation tuple carries no author; the manifest has NO author/agent/nomen field at all; the verifier checks bytes not identity. Jurist's "occasional resolve → deferred holds" is satisfied a fortiori (zero < occasional). ⇒ **additive Agent/Nomen registry (no per-work field) confirmed; `agent_id`-required stays deferred/emergent via A3's registry-linkage metric.** Minor: `pattern_finder.py` was a false grep-match — 'nomen' inside 'phe·nomen·ology' (census-through-a-pattern; substrate read cleared it). Next A1 move = design the registry shape (a vision-fork for the steward: where it lives + schema + appellation join), not a unilateral build.
- 2026-07-07T19:30 — **A1 registry v1 LANDED (chamber `703efcf`, local).** Steward's "how do serious/university libraries handle this?" redirected me to RESEARCH the identity model rather than invent one → grounded in **library authority control** (IFLA-LRM Agent/Nomen, RDA relationship designators incl. the 'attributed name' designator, attest-with-basis = MARC 670, identifiers-as-anchor), primary-source-verified. That sharpened the trust-thesis handling (Buddha = person + *attributed*, not asserted author). Built `scripts/build_agent_registry.py` (generative, explicit CURATION table) → `_curation/agent-registry.yaml`: **134 Agents / 143 strings / 222 of 1285 files (author coverage SPARSE ~18%).** Steward confirmed ALL judgments (11 merges, 11 attribution incl. 3 borderlines, 5 compounds held, 4 frontmatter defects flagged). Tool logged (tool-evolution-log). **Follow-ons (tracked in the artifact):** resolve 5 compounds w/ roles; 4 defects → frontmatter sweep; test_tools.py integration; C fills identifiers + the 2 pseudonyms + French Nomen-forms. **REVIEWED-49 tail now:** A3 (self-audit PROPOSAL), B(i)/(ii) (licence field, PREMIS vocab), C (VIAF/ISNI/Wikidata → the registry). **This session shipped A4+B(iii) AND A1** end-to-end, loop intact throughout.
- 2026-07-07T19:45 — **Skill-rewiring DONE (MemPalace wind-down STAGED PLAN item 3).** Steward: "push, then skill-rewiring, then wrap (wraps are faster without mempalace)." Pushed both chamber commits to Gitea (`34c39f1..703efcf`, clean). Rewired `/wake-up` (§2.b MemPalace 5-step → files-layer reconstruction; §2.e upgrade-check retired; §5 constraints inverted) + `/wrap-up` (§4 drawer/diary → session-file-is-the-record; §5 kg calls → append `knowledge-graph.jsonl`; §8 template). Verified no live `mempalace_*` calls remain; typography palace KEPT; provenance notes on both; recorded in skill-harvest register + winddown tracker. **THIS wrap is the first MemPalace-free wrap.** Steward's mixed feelings re: MemPalace time lost → the owed **BMF lessons report** is the vehicle to distill it forward for CapableMind (parked to the decommission slot with items 1/2/4). Remaining decommission: disable hooks, remove MCP server, cold-archive, + the BMF report.

## 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.
- 2026-07-07T18:35 — **A4+B(iii) RATIFIED + LANDED (REVIEWED-51).** Steward ratified; landed as chamber-library `7d1d8d3` (local, not pushed — Gitea/steward's call). Four steps executed with proof: v2.0.1 frozen byte-identical (cmp ✓, 763 lines) → canonical bumped v2.0.1→v2.0.2 (§I subsection + header note) → CLAUDE.md pointer → commit. Bounded-diff verified (canonical = only the header note + subsection; CLAUDE.md = only the pointer). REVIEWED-51 draft written to steward's Desktop for placement (executor doesn't write ~/REVIEWED.md). PENDING-51 marked LANDED. **A4+B(iii) closed.** First REVIEWED-49-tail chamber item shipped this session end-to-end (draft → primary-source verify → jurist gate → ratify → land), loop intact at every step.
- 2026-07-07T18:20 — **A4+B(iii) editor-gate PASSED; held at the ratification boundary.** Jurist ruled 1/2/4/5 pass-as-drafted; Q3 gated on one fact (§IX coverage-ledger + honest-degradation independently live, or entangled with the [OPEN] silence-as-finding?). Confirmed by substrate read → Case A: §IX's own `Still open` text settles both + separates silence-as-finding → citation stands as drafted, NO edit. Ruling captured verbatim (`library-science-A4-Biii-RULING-2026-07-07.md`); PENDING-51 updated. Draft final. **NOT landing the constitutional edit without steward ratification (REVIEWED-51)** — the loop is load-bearing; jurist gate ≠ steward ratification.
- 2026-07-07T17:58 — **PENDING-51 filed (chamber A4 + B(iii)); boundary NOT crossed.** Steward authorized the thread (A4+B(iii)). Diagnosed against the substrate: `collections as data` has **zero** hits in the live spec → A4 is preventive/recording (nothing to redirect-in-place), B(iii) is the term's first entry → collapse to ONE §I subsection ("The corpus as data — and the warrant it does not carry"), the A4 boundary written *into* B(iii)'s introduction (honours the RULING flag). Drafted in house voice; filed for the §Governance editor-gate per the A2/REVIEWED-50 precedent — spec is never edited in place. HELD for jurist editor-gate + steward ratification before landing (v2.0.1→v2.0.2 patch supersession). The loop is load-bearing; did not self-ratify the constitution.

## 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.
