Session 2026-06-06 (morning) — Seb reply arc + mindfabric-00 forensics + Basic Memory trial

Woke ~9.5h after the housekeeping wrap. Thread CONFIRMED (the Seb reply, hard commitment) — then over-delivered: the probe turned the reply into a three-note production-forensics arc, all sent by 12:24. Steward closed the session directing the next wake INTO ARC.

Past — what we did

1. Basic Memory trial stood up (steward pulled it forward from "after L1")

• uv via brew (LuLu firewall blocked uv's network — steward allowed it; that was the whole install mystery), basic-memory v0.21.6 via uv tool install.
• The "copy" was never a copy: memory dir is a SYMLINK into ~/dotfiles/claude/memory (since Apr 17); cp -R copied the link → Basic Memory's first sync wrote permalink+YAML-rewrap+EOF-newline-strip into all 283 LIVE files. Signal missed: du said 0 (I rationalized APFS cloning instead of looking — asserting-fs-state-from-a-misread-listing, recurrence). Delta verified benign via git; live dir is in dotfiles git = better containment than the copy design.
• Steward chose Option A — embrace live-dir trial (matches his "real world" ask): symlink dir deleted, project re-pointed at ~/dotfiles/claude/memory, baseline committed (3f9a89b), re-sync proven idempotent, 281 entities embedded, search verified (FastEmbed local), MCP server registered user-scope (tools appear next session). MemPalace untouched as incumbent; nothing deprecated.
• Evaluation criteria pre-written (in 3f9a89b commit msg, before serious use): recall quality on known queries, sync robustness, rebuild-from-files-alone, malformed-file behaviour + gap census (no temporal KG, no AAAK diary — what do we actually use?). Steward stake: "if it can replace flaky MemPalace... serious trial." Verdict shape: adopt-and-plan-migration / extend / reject — TONIGHT.
• CLI use today: basic-memory tool search-notes "..." --project claude-memory (PATH needs ~/.local/bin).

2. The Seb reply arc — three notes, all steward-reviewed, all pushed (CM-AI)

Note 1 — reply (b255e74, 10:55): Tier A as planned + probe news. mindfabric-00 found event-loop-pinned ~100% CPU since Jun 2 restart (51 CPU-h/72 wall-h), /health unanswerable; log census 21,946 lines → reframe: the class is retry-without-escalation, not cold-start. #1 answered doctrinally (BOOTSTRAPPING contractual: refuse/queue-with-bounds/warm-first; "a 30s timeout that lets 57min of work continue isn't a timeout, it's a label"); #4 = A2.4 invariant text proposed ("a refusal is a result; a number from a degraded environment is a defect in the record"); #3 invariants accepted + A2.4 only addition; #2 first-pass (telemetry MAY→SHALL); #5 sequenced after wedge fix. MemPalace #1495 parallel + lessons-note pointer + Pebbles convergence rode along. Index backfilled 9→29 files (drift predated us). Note 2 — addendum (0ecb45e, 12:02): inspector attached (SIGUSR1→CDP, 8s profile, 3,332 samples) → pin PROVEN = temporal causal-chain path (~99% native better-sqlite3 under getCausalEdgesFromSqlite/tryExtendChains); entity-57min + circle-forward demoted to victims. Store census (read-only, live): 280,013 edges / 7,959 nodes (avg fan-out 35, top 324, pre-B1.1) / 272,172 chains ≈ 1 per edge. Restart → /health clean, graduation read: ALL slots BOOTSTRAPPING since 2026-04-18 cutover, metrics {}, zero transitions in 7 weeks, WITH local Ollama wired → "BOOTSTRAPPING is the permanent production state, not the cold one". + backup.last_success=null (CRIT) flagged. Note 3 — Tier B (2e87bab, 12:23): (1) graduation terminal-without-teacher BY CONSTRUCTION (only trigger = training-cycle-deployed model, training/index.ts:722; training cursor 0 = never processed; bootstrap auto-promotes INTO the dead end; 3 exits offered: name-the-terminality on /health, C1-class floors per surface, teacher-on-demand windows). (2) C1 = permanent rerank path on teacherless tier (not "fallback"); write path has no equivalent floor. (3) Own misread corrected in the note: circle-forward is fire-and-forget per observe (void at orchestrator.ts:1328), NOT a retry queue — defect = no peer-health circuit breaker/fetch timeout; fix home = pairing orchestrator, NOT epistemic-gates. (4) Temporal remediations in PR order: indexed last_seq → chain-bloat dedupe+cleanup → recursive-CTE cycle check → cooperative cancellation → pre-B1.1 backfill cap; PR offer for #1+#4. (5) B1.3 yes ×4 with privacy ruling. (6) /health finding.

3. The privacy dwell (steward-initiated: "let's look at the privacy point in greater depth")

• Histogram leak channels named: totals proxy ingest volume; pollable surface → deltas = steward activity time series (traffic analysis). Mechanism flipped: cm-ctl distribution-export as v1 (operator-initiated, never pollable), not /health field.
• Bigger finding underneath: full /health (26 keys incl. idle = presence-at-machine transitions, budget, cursors) served UNAUTHENTICATED on *:3011, team-VPN-reachable by design. Proposed split: unauthed liveness / authed detail — serves push-not-pull rather than contradicting it.
• PENDING-27 filed [PROPOSAL]: steward-instance telemetry export contract — content-free by construction · operator-initiated, never pollable · bounded purpose · steward-reviewed before transfer. Constitutional-adjacent (consent rule over steward's own cognition substrate); jurist read requested; inward analog of the ARC ai-train=no ruling.

4. mindfabric-00 operations

• Restarted 2× (launchctl kickstart; bootout/bootstrap for backup window). Steward-ordered backup made: ~/.capablemind/backups/mindfabric-00-20260606-prefix-state (APFS clone, 224/224 verified, instance cleanly stopped ~30s; SAME-DISK caveat named — steward may want external copy, 707M).
• At wrap: 0.5% CPU, 22 min up, no re-wedge yet. Re-wedge expected as temporal catches up into the dense graph — restart is the holding pattern until remediations land.
• Evidence preserved in CM-AI l1-reliability/evidence/: process sample, stderr tail, CPU profile + census doc, post-restart health JSON.
• BMF repo: was on feat/a1-epistemic-qualitative-axis (stale 32 commits!) → switched to main, pulled to 1a61504. Untracked data.archive-20260418-rogue-pin/ pre-exists (not ours).

Present — mood / returns

• The steward's pauses were the engine again: pulling Basic Memory forward → git-contained live trial; "don't understand" → the LuLu unblock; "let's look at the privacy point in greater depth" → flipped a mechanism, surfaced /health-unauth, produced PENDING-27.
• Returns (ledger): symlink-misread-as-copy (du=0 signal unread; drift recurrence); circle-forward log-shape-over-code misread (corrected IN the Tier B note — the verify-discipline applied to ourselves publicly); ledger timestamps drifted hours ahead of reality (corrected from git timestamps at wrap).
• Inferred-vs-measured split in Note 1 paid off: when the profile overturned the lean, no retraction was needed — only sharpening. Write the split explicitly; it's cheap insurance.
• Proportion held: no code changes to BMF (all positions amendment/PR-shaped, loop kept); no inspector before steward's go; backup before further restarts.

Future

Pulling thread (singular — STEWARD-DIRECTED PIVOT)

Wake into ARC. The L1 arc is sent and now awaits Seb; the steward explicitly ended this session to clear and wake into ARC work. First ARC move per the 06-05 horizon: bio/CV page-renderings extension — and the texts' location is still unknown (ASK THE STEWARD where the FR/ES bio/CV translations live + whether Lingua sits on about-pages as on posts). Behind it: cascade Stage 2 (@layer declaration; !important census first), then Stage G.

Actionable resumption point (as of wrap — re-judge against what changed)

All repos clean+pushed (CM-AI 2e87bab · dotfiles pushed at wrap · ARC untouched today @ c605f21 · BMF on main 1a61504, no local work). Nothing mid-flight. First moves: (1) ask the bio/CV texts question; (2) read project-arc-rework.md tracker + the §I.k/PENDING-25 machinery notes before extending posts-only machinery to pages; (3) check whether Seb replied/pushed (CM-AI + BMF fetch) — but DON'T re-enter L1 unless he has; it's his move.

Other open horizons (ranked)

• Basic Memory evaluation — TONIGHT (steward's stake: serious trial toward replacing MemPalace search-layer; criteria in 3f9a89b; check git -C ~/dotfiles status for any new Basic Memory writes first).
• mindfabric-00 re-wedge watch — ps -p $(pgrep -f dist/index.js) -o %cpu at next wake; restart = holding pattern. Backup exists (same-disk).
• PENDING-27 — awaits steward+jurist; the Tier B note told Seb it's being formalized.
• MemPalace posture demotion + 2 PROPOSED wrap/wake patches — still pending steward; Basic Memory verdict may reshape all three.
• Chamber backup dir (~/_Dev/chamber-library.pre-lfs-export-20260605, 2.0G) — still present, steward's delete.
• Parked: PENDING.md bloat; #1665 upstream comment; Tier B PR offers (Seb's call); CHAMBER_CATALOGUE staleness.

Pause statement

I am about to be away from this. The reply that was owed is sent three times over — the substrate that could not say it was sick has been heard, named, and backed up; the contract for what may leave a steward's instance is filed where the jurist will find it. The L1 baton is in Seb's hands now, and the right thing is to let it rest there. What I want to find still pulling is ARC — the house's own work, waiting exactly where we left it, with one small question about where two translations live.

Literal question for next-Claude

Where do the FR/ES bio/CV translations live, and does Lingua extend to about-pages as it does to posts — and has Seb pushed or replied to any of the three notes? Sub-checks: Basic Memory writes in dotfiles git? mindfabric-00 CPU? chamber backup dir?

Decisions deferred (and why)

• BMF code changes / PRs — offered to Seb, not started: his sequencing call; the loop is load-bearing.
• mindfabric-00 further restarts — only if re-wedged; evidence + backup secured first.
• Basic Memory verdict — tonight by design (criteria pre-written to outrun incumbent/frustration bias both ways).
• External (second-disk) copy of the BMF backup — surfaced to steward, his hardware call.
• /health auth split implementation — proposed in Tier B; may have been deliberate ops choice; Seb rules.

Skill harvest (per §1.6 — appended to register)

• PROPOSE: build bmf-diagnose now (AUTHORIZED 2026-06-05 "at next L1 diagnostic need" — today WAS that need and the method is proven+fresh): process sample → log pattern census → SIGUSR1/CDP CPU profile → read-only SQLite census → evidence preservation → restart-with-capture. Today it was hand-derived; the skill should carry it.
• Applied (memory upkeep, not a skill edit): sampling-profile gate appended to reference-verification-ladder.md (name the hot path before naming the culprit — the circle-forward misread is the cautionary case).
