Question
Reduce the remaining cold lineage scan floor without weakening mutation detection or changing accounting totals.
PR #44 profiles the retained corpus at roughly 74 seconds for pass-one discovery and 74 seconds for pass-two document loading, while reconciliation is down to about 15 seconds. The parser still performs separate summary and evidence passes and rebuilds overlapping identity/model evidence.
Acceptance
- profile signature hashing, JSONL parsing, metadata extraction, model tracking, and observation construction separately
- preserve exact file-change rejection before/during pass one and pass two
- avoid retaining full observations during discovery
- demonstrate unchanged frozen UTC rows/totals
- materially reduce discovery or load time on the retained corpus
- keep cancellation responsive and memory bounded
