incremental_extension_build	done		Extension builds fingerprint inputs and outputs per independently cacheable artifact: - Langium generated sources / TextMate grammar - logo media - generated marketplace README - each of the five Vite webviews separately - extension-host / language-server esbuild outputs Host napi staging ( [extension_host_native_stage] ) always runs: cargo is incremental locally; Azure stages matrix artifacts and skips a second cargo compile in the package job. A step is skipped only when its command / input fingerprint and current output-content fingerprint both match the cache under `packages/extension/out/`. Missing, changed, or manually edited output invalidates that step. Fingerprint walks skip `node_modules` so Vite scratch files under `.vite-temp` and installed deps do not race or inflate hashes; dependency identity stays in `pnpm-lock.yaml` via shared inputs. Webview output fingerprints cover each complete emitted directory, including future lazy chunks. Host-bundle inputs include bundled phonebook data as well as workspace package output. TypeScript retains its native `tsc -b` project-reference incrementality. TextMate syntax copies are cached by content; Cursor-skill sync still runs because it targets workspace-external state. `pnpm run build:force` / `node scripts/build.mjs --force` bypasses all cache entries. `vscode:prepublish` uses forced mode with `--skip-native` so `vsce package --target` cannot replace a staged per-target `native/` with the packaging agent's host binary ( [distribution.vsix_export] ). `clean` removes `out/`, including the cache, so clean builds remain cold. Root `pnpm run build:ext` delegates only to the extension package. The extension build generates Langium artifacts when their fingerprints change, then its `tsc -b` builds language / analytical project references before downstream fingerprints are evaluated. It does not rebuild unrelated CLI, MCP, site, or test projects.	0.045
