 # Completed slices
 
+## Dev-Rewrite incremental compiler boundary
+
+### Changed
+
+- Added an opt-in source-scoped adapter manifest and extraction contract while preserving Release
+  1 complete projections.
+- Added persistent extraction caching with fingerprint, path, extractor-version, dependency, and
+  project/adapter identity invalidation.
+- Added reverse-dependency invalidation for added, changed, renamed, deleted, and dependency-changed
+  sources.
+- Added manifest-only stale-state checks so normal MCP reads do not reconstruct the complete
+  projection.
+- Added full/incremental equivalence verification and deterministic build metrics.
+- Added first-class relationship-only proposal updates over the existing hash-bound projector.
+- Added a lazy function-scoped logic-projection boundary outside the primary architecture graph.
+
+### Verification
+
+- Tests cover cache hits, reverse invalidation, renames, dependency changes, deletion, corrupt
+  caches, failed extraction, atomic preservation, manifest-only stale checks, relationship-only
+  proposals, lazy logic persistence, and full-build equivalence.
+- Strict Pyright, Ruff, formatting, compilation, warning-strict tests, web checks, dependency
+  audits, source/wheel builds, and isolated wheel installation pass.
