+## 2026-08-02 - DocForge 2.0 release
+
+- Verified the unreleased explicit accepted-writer policy at development commit
+  `7b21541ab37c35dc9f3d47f631fef0c1884f9525` against released `v1.4.0` commit
+  `f9a05f868eec6c35e2b74a69467459e6ff2190bf` in isolated locked environments.
+- Preserved same-identity application as the default, kept contributor processes without an
+  application tool, and proved explicit allowlisted application with creator and applier receipts.
+- The development repository gate passed 142 contract tests plus 272 subtests, 381 complete tests
+  plus 422 subtests, three accessibility flows, and all static, build, documentation, and smoke
+  benchmark checks.
+- Compatibility passed 116 tests plus 263 subtests, concurrency and application passed 31 tests
+  plus 2 subtests, recovery passed 72 tests plus 62 subtests, and adoption, reproducible-artifact,
+  migration, secret-scan, and anonymous fresh-clone release gates passed.
+- All full maintained benchmark tracks passed. The median absolute difference across 66
+  multi-sample operations was 0.71%, exact adapter graph and Logic evidence matched, and all six
+  representative task answers remained exact.
+- Released the verified candidate as `2.0.0`, giving DocForge2 an unambiguous distribution and
+  executable identity while preserving its versioned schemas and compatibility contracts.
