Bug: gitleaks (rule `ru-phone-unmasked`) caught `79135191264` in 3 lines
of docs/observer/episodes-2026-05.jsonl during brain-retro #3 push
(963379c3). Stop-hook PII-filter was not masking bare-format Russian
phone numbers (without the `+` prefix).
Root cause:
const RU_PHONE = /\+7\d{10}/g; // requires literal '+7'
Free-text observer episodes captured phone `79135191264` in field-value
context (`call client 79135191264` / `phone 79135191264 in payload`),
slipping past the existing filter.
Fix:
const RU_PHONE = /(?:\+7|\b7)\d{10}/g;
The `\b7` branch catches bare format with a word-boundary on the left,
avoiding false-positives inside long digit sequences (timestamps, IDs,
hashes). False-positive guard verified via test:
'id 1796133619135191264999 not a phone' → unchanged.
TDD cycle:
- RED: 3 new tests + 1 sanitizeWithCount test (4 fails on bare phone)
- GREEN: regex extended, 24/24 file tests pass, 373/373 full tools
suite GREEN (0 regressions across 18 files).
Cleanup: applied sanitize() to docs/observer/episodes-2026-05.jsonl;
11 lines touched (3 phone-leak lines + 8 with other PII patterns).
gitleaks now finds 0 leaks in the file.
Pravila §5.2 (no PII in commits) + 152-FZ (phone is regulated PD).
Closes DO-PII-1 (see memory observer-pii-leak-2026-05-23).

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. Schema v2 (schema_version: 2): the 5 mandatory fields +decision_provenance(who chose the node),environment(economy_level / model / post_compaction / session_turn / parallel_session),task_size,task_ref,prompt_signal, and anoutcomethat isunknownat write time (refined by/brain-retro). On an internal hook failure a minimalobserver_errormarker line is written instead of a silent skip. Written bytools/observer-stop-hook.mjsviatools/observer-transcript-parser.mjs.notes/YYYY-MM-DD-<slug>.md— optional MD notes for sessions with qualitative history.STATUS.md— auto-generated dashboard.

Lifecycle
- Write: every Stop-event appends one JSONL line, parsed from the session transcript (Stop-hook).
- Aggregate:
/brain-retroskill reads JSONL each sprint, proposes regulatory candidates. - Surface:
STATUS.mdshows controllers + monthly stats. - Self-prune: C3 warns if 54 weeks pass without any read of observer files.
Routing-tag discipline
When the user dictates a specific method/node (e.g. «запусти discovery-interview»), Claude must emit one line in its response:
<!-- routing: provenance=user_directed_method node=<chosen> counterfactual=<node Claude would have chosen autonomously> -->
The Stop-hook routing-gate (tools/observer-routing-detector.mjs + routingGateDecision) detects a dictated method; if the tag is missing it returns decision: block, so the turn cannot end without the tag. The gate fires at most once per turn (stop_hook_active guard). This makes decision_provenance reliable — factor analysis can separate a router error from a user-dictated one.
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.

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.jsonalready 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.
