Closes brain-retro 2026-05-20 #16 — when the next prompt is 'neutral'
(no correction/approval/new_task markers), interpret as silent success
('no objection') and surface as soft_success. Slightly weaker than
explicit approval — labelled separately so brain-retro can show
breakdown.
4 new vitest tests, 324/324 GREEN.

Closes brain-retro 2026-05-20 #14 — `environment.session_turn` уже значит
'turns since last compaction' (parser counts from lastCompactIdx + 1).
Ось матрицы под именем 'session_turn' путала с глобальным turn-номером.
Семантика данных не меняется, только имя axis в FACTOR_FNS.
Existing test renamed; new explicit test verifies new name present and
legacy name absent.
1 new vitest test + 1 renamed, 320/320 GREEN.

Bug: findCausalChains flagged a chain whenever two episodes shared any
file. CLAUDE.md / MEMORY.md / STATUS.md / episodes-YYYY-MM.jsonl /
memory/*.md are touched by almost every turn (memory store, status
regeneration, normative-doc updates) — sharing them is not evidence of
causality, just baseline noise. Result: spurious chains on hot files
crowded out the genuine signal.
Fix: HOT_FILE_PATTERNS regex list + `isHotFile(path)` predicate. In
findCausalChains, filter hot files out of BOTH the errored-episode file
set AND the candidate-shared list. If only hot files were shared → no
chain. If a non-hot file is also shared → the chain stands and the
sharedFiles list contains only the non-hot ones.
Tests: 4 new cases — CLAUDE.md / memory/*.md / episodes/STATUS/MEMORY
sharing yields no chain; a turn sharing both CLAUDE.md AND /src/app.ts
yields a chain with sharedFiles=['/src/app.ts'] only. 33/33 analyzer
tests green.

Bug: inferOutcome flagged `blocked` whenever errorCount > retryCount across
the turn's events. But the parser emits an `error` event for ANY tool_result
with is_error=true — including expected failures: TDD failing-test-first,
grep returning nothing, git commands with intentional non-zero exit. On
TDD-heavy turns (project's standard discipline) this systematically marked
turns as blocked even when they ended on a successful tool_use.
Fix:
- Parser (extractProcessEvents): walk turn from end, find the LAST
tool_result; if its is_error=true, emit a single `unrecovered_error`
event. Distinguishes "turn ended on failure" from "errors recovered
later". The original per-is_error `error` events remain (useful as raw
factor signals).
- Analyzer (inferOutcome): replace `errorCount > retryCount → blocked`
with `events.some(kind === 'unrecovered_error') → blocked`. Same
ordering preserved (interrupt > blocked > rework/success/unknown).
Tests:
- Parser: emits unrecovered_error when last tool_result is_error;
does NOT emit when turn ended on a successful tool_result;
does NOT emit for turns with no tool_results.
- Analyzer: blocked iff unrecovered_error event present (not raw count);
events=[error, error, retry] → success (no unrecovered_error).
142/142 vitest green (was 128).

P0.1b: inferOutcome emits 'blocked' when a turn had more error than retry
events (an unrecovered tool failure) — previously the enum value was dead.
P0.1c: 'failure' documented as deferred to the phase-2 agent-judge. It is a
judgment (work wrong AND never corrected), not deterministically recoverable
from a transcript; a wrong-then-corrected turn surfaces as 'rework'.
P1.1: analyze() drops v1 episodes (no schema_version 2) — they lack
environment/prompt_signal/decision_provenance and polluted the factor
matrix. Reports v1SkippedCount.
P2.1: session_turn (bucketed early/mid/late) and parallel_session added to
FACTOR_FNS — closes the schema↔matrix mismatch (both were captured in the
episode but absent from the factor axes).

buildFactorMatrix already buckets decision_provenance.kind dynamically
(brain-retro-analyzer.mjs:112) — no production change needed. Test
pins that user_chose_from_options is counted on the provenance axis.
12/12 brain-retro tests GREEN.

Pure deterministic Layer-4 aggregation module (spec §6) for the /brain-retro
skill. Exports: dedupeEpisodes, inferOutcome, groupEpisodesToTasks,
findCausalChains, buildFactorMatrix, analyze. Read-only — never writes JSONL.
11/11 tests green. CLI smoke: 10 real episodes → valid JSON with all 5 keys.
