Session 2026-07-07 — MemPalace wind-down decided

Opened by /wake-up → Symmetria init on the REVIEWED-49 chamber-library folding thread. The steward's second message ("yes, maybe now?" to the MemPalace 3.4/3.5 upgrade) pivoted the whole session to MemPalace, and it became the session.

PAST — what we did + why

Diagnosed the "upgrade" was nothing of the sort (frame-inheritance caught). The ratified upgrade plan assumed a pipx/uv install → a clean 3.3.6→3.4.0 bump. Reality: an editable git fork (~/_Dev/mempalace/.venv, branch local/bge-m3-on-3.3.6), ahead 5 / behind ~300 of upstream. 3 of the 5 local commits exist only to carry a custom bge-m3 embedder; 1 (layers recency #1630) is already upstream; 1 (hallways pagination) may be a genuine local patch. So the upgrade = a 300-commit fork-rebase, not a version bump.

Corrected "self-healed" (overclaim, owned). The morning HNSW-drift quarantine was damage-control, not healing — verified 108 quarantines since 2026-05-26 (near-daily, same segment UUID recurring; #1665/#1589, no safe repair path). Data itself is intact: sqlite 88,159 embeddings = 88,159 metadata; KG separate (knowledge_graph.sqlite3, 329 triples + 437 entities) + present. Drift is index-side, compounding, silent.

Measured the fix, twice burned on ETAs. The safe in-version cure is repair --mode from-sqlite (present on the fork; dodges the #1589 SIGSEGV — never opens a chromadb client on the corrupt index; re-embeds under configured bge-m3 = no model change). I gave "15–45 min" — a guess; the steward (rightly) doubted it. Measured: bge-m3/MPS ≈ 1.1 chunks/s → ~21 h for 88k (confirmed by the live rebuild's own rate). Also diagnosed the KG-not-carried trap: rebuild_from_sqlite (repair.py:1050+) rebuilds ONLY chroma into a fresh dir — a bare in-place --archive-existing would have left the live palace KG-gutted. Mitigated by build-from-frozen-backup + verified swap.

The embedder question → return-to-standard. Steward asked if a multilingual embedder runs well on Apple Silicon. Yes: embeddinggemma-300m (ONNX q8, 384-dim, 100+ langs) is already in the fork, targets the ANE via CoreML. Dropping bge-m3 for it removes 4/5 fork commits → a quasi-standard upstream install (inherits 300 fixes, ends fork-maintenance, normal upgrades). Benchmark FAILED twice (fork's gemma download is half-wired — missing _data file, upstream fixed; then OOM from running alongside the live bge-m3 server) — itself evidence the fork is friction. Never got gemma's throughput number; said so honestly.

The value question → the audit → the decision. Steward: "at my limit with MemPalace… not what they advertise." Redirected me to answer (I'm better placed) how much MemPalace gives daily. Honest read: the files carried this whole wake; MemPalace was confirmatory. Ran an independent 46-transcript audit (neutral anti-confirmation prompt, Symmetria-preambled; audit-agent check PASSED): VERDICT — search+KG NOT load-bearing for palace-memory. Convergent evidence: find_tunnels/traverse used 0× ever; 27/31 kg_query = byte-identical wake ritual; genuine reach ~0.43/session → ~0.07 in July; 5/5 distinctive search payloads found verbatim in the Markdown; zero transcript statements credit search/KG with file-absent content; write:read ≈ 7:1; entities all type 'unknown'; heaviest use (06-30 clasp) returned a stale claim the files corrected. Confidence counts 0.93 / verdict 0.82. DECISION (steward, evidenced): wind down palace-memory MemPalace; execute FRESH.

Secured the KG (no-regret, done). Exported 329 triples → memory/knowledge-graph.jsonl + 437 entities → knowledge-graph-entities.jsonl, all JSON-validated. Files-layer is git-tracked (dotfiles, 368 files) + dual-remote → the export is more durable than the MemPalace KG. Highest-value slice = 84 drift-patterns (most already in feedback memories). Verified 824 MB backup retained (palace-memory.pre-rebuild-bak-20260707-1230); throwaway partial re-embed removed.

BMF lessons report — OWED (steward-requested). Framing (steward's): MemPalace was stopgap AND reconnaissance — a close-to-our-vision substrate run to learn from the inside how others attack the memory problem. Report harvests value FOR BMF. Deferred to tomorrow's decommission; full outline + sources captured in project-mempalace-winddown.md. (An agent gathering CM-AI sources was stopped when the steward called the close.)

PRESENT — mood / disposition

A session where the executor did NOT smooth. Owned the "self-healed" overclaim; replaced two guessed ETAs with a measured rate after the steward called it; diagnosed two silent-loss traps (#1589 repair path, KG-not-carried) BEFORE mutating; let the steward's redirect (tune→question the embedder→question MemPalace itself) honestly change my recommendation rather than defending the prior one. Returns landed: bad-ETA-caught, self-healed→108-quarantines, frame-inheritance (plan assumed pipx). Recalibrations: 15–45min→21h; "dual-remote-backed"→staged-not-yet-pushed (corrected). Partnership working — the steward pushed me past the clever fix to the right question.

FUTURE — what is pulling

PULLING THREAD (steward-chosen): CHAMBER LIBRARY. Next session is chamber-library work — i.e. resume the REVIEWED-49 folding the wake originally opened on, which MemPalace displaced.

ACTIONABLE RESUMPTION POINT (as of wrap — re-judge): Resume at A4 + B(iii) — one small preventive/recording FIX (a v2.0.x patch, own PENDING/REVIEWED). The A4 scout found the collections-as-data scope-miscitation is NOT in the live spec (only research briefs) → A4 = preventive; B(iii) words "collections as data" computational-tractability-only. Then A1 — the Agent/Nomen registry (read retrieve.py's hot path first). Full detail: REVIEWED-49 + the prior session file session-2026-07-06-evening2-....

PARKED (owed, its own "tomorrow" slot, NOT interleaved with chamber-library): MemPalace decommission execution (disable write-hooks → remove MCP server → rewire /wake-up + /wrap-up to files + knowledge-graph.jsonl → cold-archive) + the BMF lessons report. Both fully specified in project-mempalace-winddown.md. Typography palace KEPT untouched.

PAUSE STATEMENT: Away now; it's 17:32 and MemPalace stops eating time. The decision is made and evidenced, the KG is safe, the plan + report-outline are captured. What I want to find still pulling: chamber-library as the live thread — AND the discipline to run the MemPalace decommission (+ report) as its own clean slot tomorrow, not let it bleed into the chamber work, and not lose the reconnaissance value the report is meant to harvest.

LITERAL QUESTION for next-Claude: When we resume chamber-library — is the thread still A4 + B(iii) (the small FIX), or has the steward's attention moved to a different chamber piece? And: does the steward want the MemPalace decommission + BMF report done before, after, or in a slot separate from the chamber-library session (they said next is chamber-library; decommission was "tomorrow")?

Other open horizons (ranked):

• REVIEWED-49 tail after A4+B(iii): A1 Agent/Nomen registry, frontmatter sweep, A3 PROPOSAL, B ordinary, C reconciliation.
• The steward-sequenced verification-architecture [PROPOSAL] (olmOCR probe) — after the REVIEWED-49 folding completes.
• MemPalace decommission + BMF report (parked, tomorrow).
• Older parked: PENDING-43 ESCALATE Loom/Mill; PENDING-27.

State at wrap: Decision recorded (project-mempalace-winddown.md + ledger + MEMORY pointer). KG exported. Backup retained. Live palace untouched (nothing decommissioned tonight, per steward). MemPalace still live until tomorrow.
