Observer infrastructure

Passive evidence-loop for the Лидерра «brain» per ADR-011.

Files

• episodes-YYYY-MM.jsonl — append-only JSONL, one line per Stop-event (one prompt→response turn). Written by tools/observer-stop-hook.mjs, which parses the session transcript (transcript_path) via tools/observer-transcript-parser.mjs.
• notes/YYYY-MM-DD-<slug>.md — optional MD notes for sessions with qualitative history.
• STATUS.md — auto-generated dashboard. Regenerated per-commit by tools/status-md-generator.mjs.
• .read-counter.json — C3 observer-of-observer counter. Updated on Read of observer files.

Lifecycle

1. Write: every Stop-event appends one JSONL line, parsed from the session transcript (Stop-hook).
2. Aggregate: /brain-retro skill reads JSONL each sprint, proposes regulatory candidates.
3. Surface: STATUS.md shows controllers + monthly stats.
4. Self-prune: C3 warns if 54 weeks pass without any read of observer files.

Privacy

PII filter (phone numbers, emails, tokens) is applied before every write — see tools/observer-pii-filter.mjs. gitleaks pre-push also scans observer files as part of full-history sweep.

Don't

• Don't edit episodes-*.jsonl manually — it's append-only.
• Don't write outside docs/observer/notes/ for hand-curated notes.
• Don't change .read-counter.json manually — it's maintained by hooks.

HK1 pre-check (Pravila ADR-010) — verified 2026-05-19

Before registering tools/observer-stop-hook.mjs on Stop event (Task B5), verified collision against 6-component economy/skill-discipline architecture:

• User-level ~/.claude/settings.json already has Stop hook: agent-type Sonnet-4.6 economy compliance verifier (analyzes transcript for claim-without-evidence violations).
• Project-level .claude/settings.json — Stop slot empty.

Result: no overwrite. observer-stop-hook will be added as command-type entry in project-level Stop array. Project + user scopes are independent slots in Claude Code 2.x — both run on the same Stop event without conflict. The agent verifier (user scope) and the JSONL appender (project scope) have non-overlapping responsibilities.
