Дмитрий a0bb11a6fb perf(brain-retro): prompt-caching split on reviewer-agent
Add buildReviewPromptStructured() returning { system, user } and route
reviewViaDirectApi through callAnthropicAPI's structured branch — same
pattern the classifier already uses (router-classifier.mjs L456-484), so
infrastructure is reused, no new transport code.

system block: static instructions + 8-dim cues + schema-version notes
(byte-identical across episodes of the same schema_version → cache key
stable within a 5-min TTL).
user block: per-episode JSON (volatile).

Effect on Opus 4.7: ~zero until system grows past 4096-token cache-
minimum or model switches to Sonnet (2048 min). Anthropic silently
no-ops cache_control when prefix is below the minimum — no error,
cache_creation_input_tokens just stays at 0. Architecturally correct
and future-proof; activates the moment either condition flips.

buildReviewPrompt() kept as backward-compat wrapper.

Tests: +5 invariants for the split + cache-prerequisite check
(system identical across two v4 episodes with different bodies).
14/14 GREEN.

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 an outcome that is unknown at write time (refined by /brain-retro). On an internal hook failure a minimal observer_error marker line is written instead of a silent skip. Written by tools/observer-stop-hook.mjs 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.
  • dashboard.html + dashboard.js + dashboard-core.js — Brain Dashboard: visualises the episode log over the automation-graph topology (4 views — Карта / Разбор / Лента / Агрегат). Run npm run brain:dashboard, open the printed localhost URL. dashboard-core.js is pure logic, unit-tested in tools/brain-dashboard-core.test.mjs.

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.

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.

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.
