Canonical sources changed after the index or viewer snapshot was built.
Normal MCP operations automatically repair a missing, stale, or invalid disposable index under a
project lock. `docforge_sync` can be called explicitly to inspect whether synchronization was a
no-op or rebuild. The CLI equivalent is:

Every complete index build also writes a disposable whole-file SHA-256 attestation. A new MCP
