#622 Views: republish only the call-graph rows whose inputs changed

View republication used to decode every file's call-graph blob and re-resolve the whole checkout, so a one-file edit took about 125 s on the AFT repository. Dispatch now decodes only changed blobs and re-resolves only files whose recorded inputs changed, using per-file facts and dependency keys in new derived tables. Rust type targets are replayed from per-file traces.

• One-file republication: 125 s down to 5.3-7.0 s on the build server. The remaining time is the existing surface replay through the Rust module domain.
• The new tables add about 11.7% to the derived call-graph database.
• Verification: a differential test compares incremental republication with a cold build over random and scripted walks that cover every method-call edit kind, with full dispatch forced off. Four mutation controls go red.
• The views_work counters gain dispatch fields for the measurement harness.

Summary by cubic

Makes call-graph republication incremental so a one-file edit no longer re-resolves the whole checkout, and fixes a Go binding staleness the new tests uncovered.

• One-file republication on the AFT repository drops from about 125 s to 5.3–7.0 s on the build server; the remaining time is the existing surface replay through the Rust module domain.
• The new tables add about 11.7% to the derived call-graph database.
• A differential test compares incremental republication with a cold build over random and scripted walks covering every method-call edit kind, with full dispatch forced off; four mutation controls go red. The walks now also cover Go, Java, and C#, and the Go walk exposed a staleness bug: package-directory listings were read without being recorded, so adding or removing a sibling .go file left unchanged callers with stale bindings.
• The views_work counters gain dispatch fields for the measurement harness, and a search-quality harness descriptor marks the change non_ranking.

Migration

• Views databases whose Go bindings predate recorded package listings rebuild cold once; the materialization version bump forces it.

Confidence Score: 5/5
