David F GliddenandClaude Opus 4.8 3f9a89b00c chore(memory): Basic Memory trial begins — sync normalization baseline (283 files) 
Basic Memory v0.21.6 first sync over the live memory dir (steward-authorized
live-dir trial, Option A 2026-06-06): adds permalink: to frontmatter, refolds
long YAML description lines, strips final newlines. Bodies untouched —
verified via full diff classification. From this commit forward, any diff in
claude/memory shows only what Basic Memory or the session writes.

Trial design: MemPalace untouched as incumbent; git status check on this dir
at every wrap; end-of-day evaluation (recall quality, sync robustness,
rebuild-from-files, malformed-file behavior).

Session 2026-03-21 — L1 reliability PR + audit + governance evolution Major session establishing three-party governance model, four L1 bug fixes, 43-finding silent degradation audit, executor agency directives. Replay running overnight for canary test. project claude-memory/session-2026-03-21

Session 2026-03-21

What Happened

Governance Evolution

  • Three-party model (steward/jurist/executor) formalized in CLAUDE.md
  • Authorization taxonomy: [FIX], [HARDENING], [PROPOSAL], [ESCALATE]
  • Executor Agency Directives added — contamination-aware operational obligations
  • PENDING.md / REVIEWED.md protocol established
  • Session protocol: read CLAUDE.md → seed → REVIEWED → PENDING → empirical log before touching code

Four Bug Fixes (branch: fix/replay-durability-contracts)

  • Bug A — Vector reprobe condition mismatch: startsWith('stub:') → broadened to any degraded state. Added storage degradation recovery via SurrealDB probe.
  • Bug B — Schema migration non-idempotency: defineIdempotent() wrapper applied to job-store.ts, checkpoint.ts, dedup.ts. Root cause was checkpoint.ts (bare DEFINE FIELD without IF NOT EXISTS), not job-store.ts as originally diagnosed.
  • Bug C — Teacher worker retry storm: Terminal error detection (credit exhaustion → suspend), exponential backoff on transient failures, log rate limiting. Confirmed: 1 log line instead of 586.
  • Bug D (Option 2) — Batch embedding during replay: Coalescing buffer in OllamaEmbeddingProvider + batched Phase 1 loop in replay coordinator. 16 events processed concurrently. ~2-3x speedup observed.

Silent Degradation Audit

  • 43 instances across 5 structural patterns
  • 5 CRITICAL, 18 HIGH, 20 MEDIUM
  • Root causes: fire-and-forget (22 instances), fixed-interval retry, recovery/degradation mismatch, state transitions that freeze, silent persistence failure
  • Key finding: 4,974 vector-relevant events in logchain (not 221) — Phase 1 at single-event embedding takes ~83 hours
  • Bug D (idle stall) identified as root cause of replay freezing every 5 minutes

Key Discovery

  • Logchain has 221 top-level events but payloads contain nested connector batch events
  • Vector module processes each nested event → 4,974 total
  • This was invisible without the audit — confirms executor agency directive is load-bearing

Files Changed (BetterMemories.io)

  • src/modules/vector/index.ts — Bug A fix (reprobe broadening + storage degradation)
  • src/factory/job-store.ts — Bug B fix (defineIdempotent)
  • src/factory/checkpoint.ts — Bug B fix (defineIdempotent)
  • src/factory/dedup.ts — Bug B fix (defineIdempotent)
  • src/inference/teacher-enrichment.ts — Bug C fix (suspension + backoff)
  • src/inference/ollama-embeddings.ts — Bug D fix (coalescing buffer)
  • src/core/keystone/readiness/replay-coordinator.ts — Bug D fix (batched Phase 1 loop)

PENDING Items (~/PENDING.md)

  • PENDING-1: Executor Agency Directive — AUTHORIZED, integrated
  • PENDING-2: Silent degradation audit — COMPLETE, authorized for follow-on
  • PENDING-3: Factory schema scope extension — ACKNOWLEDGED
  • PENDING-4: Bug D idle stall — AUTHORIZED, next PR
  • PENDING-5 through PENDING-9: from audit findings (transport backoff, manifest persistence, Phase 2 handling, fire-and-forget replacement, hysteresis)
  • PENDING-10: Option 1 (skip embedding during replay) — authorized for next PR

Current State

  • BMF running (PID 53403) with all 4 fixes
  • caffeinate (PID 54925) preventing sleep for 12h
  • nohup keepalive (PID 54926) sending MCP observe every 4 min
  • nohup monitor (PID 54927) logging to ~/.capablemind/logs/replay-monitor.log every 10 min
  • Vector cursor at 114 of ~4,974 at last check — advancing in bursts
  • Phase 1 not yet complete — expected overnight
  • MCP disabled in Claude Code to prevent BMF restart

Next Session

  1. Check cat ~/.capablemind/logs/replay-monitor.log
  2. If Phase 1 complete: confirm canary, test recall, complete PR artifacts per seed instructions
  3. If not complete: assess whether Bug D (idle stall) or volume is the bottleneck, consider reducing Phase 1 window
  4. File GH issues A, B, C, D
  5. Submit PR
  6. Update PENDING.md with SESSION-LOG

Seb Context (from thinking folder exploration)

  • Spec-first methodology, 97 docs, 85k lines — runtime not yet held to same standard
  • Architecture + historiography background — audit findings will be recognized as same discipline applied to runtime
  • Giving-back document, public debt framing — this is a calling, not a job
  • His biggest unknown: whether training flywheel produces meaningful quality improvement
  • Three-entity structure (Skemantix, CapableMind Inc, WhySo Ltd) — long-term thinking
  • Cold start, forgetting, multi-user, L1/L2 boundary — all have design-level answers in his specs
