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.
* Reduce repeated PR setup and transcript timing waits; add hosted comparisons
* Align parallelism contract with Node-only external rebuild toolchain
* Record hosted coverage and launch package, store, and cancellation comparisons
* Apply hosted Windows setup savings and remove measured test waits
* Keep measured PR package gains and remove completed comparison jobs
* Report measured test counts with precise units
