Conversation
Cache declaration enumeration, file grouping, ID lookup and reverse hierarchy independently on the snapshot. Share typed-data navigation before hover presentation and cache requested-file outlines. Preserve parent/child ordering and navigate multiple-inheritance wrappers to their bound declarations. A/B vs 3912118: service-navigation/unwrap time -17.0% (4.1% noise), peak -3.8%, kept +2.9%. Snapshot-first mixed time -8.3% (6.9% noise), peak +5.7%, kept +7.5%; source-first time within 19.4% noise, peak +3.4%, kept +7.5%. Accept the about 1.93 MB snapshot-local retention, chiefly the outline cache. Hover/inlay times stay within noise, kept +0.7%/+1.0%. Diagnostic-only query caches remain unpopulated, with allocation effectively unchanged. Add a sparse three-edit navigation workload with fixed request counts and timing/allocation reach checks. Keep recovery documentation technical and recorded import/checkout paths relative, including wrong-checkout errors. Gate: Ruff, format, strict mypy, 5879 passed/69 skipped/1 xfailed. Navigation and both mixed linearity checks pass. Record phase/noise limits and cache ownership. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
Performance and acceptance
A/B control: 3912118. Navigation sequence time -17.0% (4.1% noise), peak -3.8%, retained +2.9%. Snapshot-first mixed sequence time -8.3% (6.9% noise), peak +5.7%, retained +7.5%. Source-first time remains within 19.4% noise, peak +3.4%, retained +7.5%. Times cover three edit/query cycles.
The full bundle is accepted with about 1.93 MB additional snapshot-local mixed retention, chiefly the outline cache (about 1.74 MB measured by release). Diagnostic-only allocation is effectively unchanged; no diagnostics speedup is attributed to query caches. Cold hover/inlay times remain within noise.
