Hook contract: reads JSON ctx from stdin (Claude Code Stop-event),
builds episode with 5 mandatory fields including primary_rationale
(7 sub-fields per spec v1.1 §5.2.1), sanitizes via observer-pii-filter,
appends to docs/observer/episodes-YYYY-MM.jsonl. Never blocks
Stop-event (exit 0 on error).
8 Vitest tests verified GREEN (6 in appendEpisode + 2 in
buildEpisodeFromContext): append/append-existing/PII-filter/
missing-required/missing-rationale-field/routing_decision-preserved
+ buildEpisode 5-field extraction + user-rationale-preserved.
Vitest config for tools/ already covers via glob ../tools/observer-*.test.mjs
(extended in B2 commit 4616308).
Per Pravila §16.2 + ADR-011 + spec v1.1 §5.2.1 (factor analysis).
