Diagnosed the "upgrade" as a 300-behind bge-m3 fork, not a standard install; the morning "self-healed" drift was 108 chronic quarantines (data intact). Independent 46-transcript audit: search+KG not load-bearing (value migrated to files). Steward decided (evidenced) to wind down palace-memory; execute fresh. KG exported to knowledge-graph.jsonl (329 triples + 437 entities). Wind-down plan + BMF-lessons report outline captured. Demote-on-promote; skill harvest appended.

# 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.
