Summary

• Remove synchronous forced GC between cache parts and after merges; rely on backpressure and normal V8 GC.
• Remove obsolete exposed-GC startup guidance and runtime flag.
• Cover concurrent multipart cold restores, completed merges, and warm byte equality.

Notes

• Targets patch/9.7.0-backpressure; no dependency, schema, storage API, or deployment changes.
• Node 25 type-check/build/lint passed. SQLite/filesystem: 16 tests passed, 1 skipped. SQLite/S3: 18 passed.
• The local candidate image passed 16 SHA256-checked cold/warm restores. A controlled 8-entry/64-part comparison showed substantial forced-GC overhead; this is not a peak-load availability guarantee. Image verification used a compiler-equipped local Node 25 base.
