+## v0.2.9 — Builtin Extension Retirement
+
+### Changed
+
+- **6 builtin extensions → standard packages**: csv-table, diff-viewer,
+  js-sandbox, katex-renderer, mermaid-renderer, and regex-tester moved from
+  `extensions/builtin/` to `packages/` with standard `js/` layout. Each
+  manifest now declares `"requires": ["chat"]` and `"type": "extension"`.
+  Built via `build.sh` like all other packages — no auto-install.
+
+### Removed
+
+- **`SeedBuiltinPackages` seeder**: Deleted `seed_packages.go` (function,
+  `builtinManifest` struct, `buildFullManifest` helper) and the startup call
+  in `main.go`. Extensions are no longer auto-seeded into the DB.
+- **`extensions/builtin/` directory**: Removed from repo and Dockerfile COPY.
+- **Seed tests**: Removed 8 `TestSeed_*` functions and `makeSeedDir` helper
+  from `extension_test.go` (~220 lines).
+- **Stale comments**: Removed `SeedBuiltinPackages` references from
+  `package_iface.go` and `trigger_sync.go`.

 | Step | Status | Description |

-| Retire builtin seeder | ⬚ | Stop auto-seeding chat-centric extensions (csv-table, diff-viewer, js-sandbox, katex-renderer, mermaid-renderer, regex-tester). Remove `SeedBuiltinPackages`, Dockerfile COPY, and `extensions/builtin/` directory. These extensions are not OBE — they're dormant until a chat surface exists to consume them. |
-| Convert to regular packages | ⬚ | Repackage the 6 extensions as standard `.pkg` archives in `packages/`. Add chat dependency metadata to manifests so they can be installed when the chat extension ships post-MVP. No auto-install — explicit install only, matching the distribution model. |
