+## DocForge2 Milestone 0 successor foundation
+
+### Changed
+
+- Preserved the complete advanced DocForge lineage in the public
+  `administrator/DocForge2` successor.
+- Committed the verified no-AST work and merged the original local-only adapter-lifecycle commit
+  without rewriting either line of history.
+- Hardened no-AST enforcement for pre-existing indexes, live visualization, and
+  canonical-application refresh.
+- Added explicit package, CLI, MCP, adapter, schema, changeset, rendering, safety, and no-AST
+  compatibility guarantees.
+- Added repository-native aggregate, contract, build, and benchmark gates.
+- Recorded cold and warm latency, startup, memory, rendering, response-size, incremental, and
+  pinned-SQLite baselines.
+- Configured `origin` for DocForge2 and `legacy` for the intact DocForge v1 repository.
+- Kept only `main` and `dev` as successor development branches. Historical legacy branches remain
+  unchanged in the legacy repository.
+
+### Verification
+
+- Gitleaks 8.30.1 found no secrets in reachable history or the candidate tree.
+- The aggregate gate passed formatting, Python and web lint, strict types, compilation, public
+  contract and schema checks, 95 tests and 44 subtests, lock and dependency validation, package
+  builds, and benchmark smoke.
+- The 1,000-node maintained baseline completed from a clean tree.
+- Every successor ref was compared with its local source before redundant public development
+  branches were removed.
+- Every recorded legacy head and the annotated `v1.0.0` tag remained byte-for-byte unchanged.
+- An anonymous HTTPS clone selected `main`, passed `git fsck --full` and the complete aggregate
+  gate, and remained clean.
+- No tag, release, release announcement, production MCP repointing, WorldForge change,
+  ScrapeStation change, storage rewrite, or self-hosting dependency was introduced.
