* perf(typecheck): pnpm tc uses the pinned Bun checker when available
bun check (Bun 1.4.3, TypeScript 7.0.2 parity, already used by CI) checks the
node project in ~29 CPU-s / ~2 GB peak vs tsc's ~98 CPU-s / ~16.6 GB. tsc's
incremental cache rarely helps agents: noEmit builds store no declaration
signatures, so the first edit to any file after a cold check re-checks every
transitive importer (a comment in src/shared/constants.ts re-checks all 18k files).
pnpm tc / tc:node / tc:web / tc:cli now pick the Bun from config/.bun-version when
it is on PATH and fall back to tsc with a one-line hint otherwise;
--compiler=native forces tsc. The pinned-Bun probe is shared with the
localization extraction check.
* build: pin Bun as a devDependency and make it the only default checker
The PATH probe left anyone without the exact pinned Bun (including a 1.4.2
global) on tsc's expensive path. bun@1.4.3 is now a devDependency, its
postinstall is allowed, and pnpm tc / typecheck:ci run that binary. A missing
binary is an error pointing at pnpm install rather than a silent fallback;
--compiler=native still selects tsc. A test keeps the devDependency equal to
config/.bun-version.
* ci: link the pinned Bun after the script-free install
--ignore-scripts leaves node_modules/.bin/bun as bun's postinstall stub, so the
typecheck runner found no binary and any pnpm-run script calling bun would hit
the stub before setup-bun's copy. pnpm rebuild bun runs only that allowed build.
Extract subprocess execution and process contracts into @orca/process-host with explicit public entry points, independent checks, and one Node 18 compatible CommonJS runtime. Migrate application consumers and integrate package builds, dependency selection, import enforcement, and runtime resource staging.
Preserve daemon startup ownership and profile isolation, and qualify development rebuild recovery and concurrent output publication. Remove unnecessary aliases, test forwarding exports, and a duplicate output scan.
Validation: full typechecks, changed-code quality, package and artifact checks, native Windows builds/types plus 306 runtime tests, and independent native reviews.
Matched full E2E controls on original main and unchanged reviewed head both pass all 17 applicable tests (nine skips). Earlier intermittent E2E failures are documented in the PR; no assertions were weakened. The final combined-tree audit preserves both branches with no import-boundary violations.
Remove one-off incident docs and committed test-results noise, move
dev/repro/bench tools under tests/tools, and relocate i18next config
into config/ so the GitHub root scrolls to the description faster.
