fix(update): stage under npm's strict script policy and let a failed update restore its service - #5856
Conversation
…pt policy With strict-allow-scripts set, npm plans the global tree before it creates the prefix layout, so `install -g --prefix` into a bare stage failed with ENOENT on <stage>/lib and every update stopped at staging. The stage is now created with its POSIX lib directory; Windows installs into the prefix itself and is unchanged.
…e recovery The service manager starts the proxy outside the updater's process tree, so it cannot join the delegated lease. A failed update ran the service repair while still holding it, the service's proxy could not start, and recovery fell through to a second, directly started proxy that later fought the service for the port. Service recovery now releases the lease first, as a successful update already does, and plans again after the release. Closes lidge-jun#5760

Merge Risk: 🔵 Low · up to The recovery change appears mergeable, but an observable service-recovery test would better protect against future lease contention and incorrect refreshes. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The update preserves its ownership and liveness checks and does not add a public entrypoint. A narrow concurrency question remains around recovery after the updater releases its lease; no security vulnerability was verified. Retained concerns

Exercise the failed-update service-recovery path.
tests/update/update-stop-first.test.ts:837-846 checks only source-text order. It does not observe the lease or execute the second recovery plan. A no-op releaseUpdateLease() would still satisfy these assertions. A recovery regression that refreshes after ownership or liveness changes would also pass.
Add a focused launcher recovery test with an observable lease and service-refresh fixture. Assert that refresh starts only after the lease is released. Change ownership or liveness between the two plans and assert that refresh is not called.

The service manager starts the proxy outside the updater's process tree, so that proxy cannot join the delegated lease:ocx startwaited for it and failed (another process owns the runtime mutation lease), the repair's health wait gave up after 21 s, and recovery fell through to a detached, directly started proxy instead of the service-managed one. A service recovery now releases the lease before the refresh, as a successful update already does, and plans again after the release, so a takeover or a live runtime found in between still stops the revival. Direct recovery keeps the lease through readiness, as before. The "replacement was refused" path goes through the same function.src/update/index.ts, which serves bun and source installs, is left alone.structure/ops/service-and-sidecars.md(the stage layout and the launcher's lease exception).Closes #5760
