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.
