Fork pull requests were pinned to GitHub-hosted runners while maintainer
PRs rode Blacksmith. That split arrived with ci.yml's first commit
(f4f990a) and was never a reasoned posture -- no rationale in docs,
commit bodies, or the ci-limits skill -- and this week's Blacksmith
tranches widened the gap: maintainer walls are ~3:36 while the last fork
PR I measured (#124633) took 13m0s. We already paid for it once in
#118530, which raised the cross-repo artifact budget to 35 minutes
because contributor PR #117992 timed out twice on hosted capacity.
Runner choice now follows author_association: OWNER, MEMBER, COLLABORATOR,
and CONTRIBUTOR get Blacksmith; FIRST_TIME_CONTRIBUTOR, FIRST_TIMER, NONE,
and MANNEQUIN stay on hosted runners, which are free for public repos, so
an unreviewed author cannot spend Blacksmith capacity. Earning the fast
path requires a landed commit, which requires a maintainer merge.
Note for anyone tempted to trim that list: maintainers report CONTRIBUTOR
here, not OWNER/MEMBER, because org membership is concealed -- steipete's
74 sampled PRs are all CONTRIBUTOR. Dropping CONTRIBUTOR would move
maintainer PRs to hosted.
Scope is deliberately runner-only: 27 runs-on clauses. The 34
dependency-cache/use-actions-cache conditions and 6 job ifs stay
fork-gated, because cache poisoning is a different risk from runner
choice -- a fork run still never writes an archive a trusted run restores.
Verified by evaluating all 25 configurable runs-on expressions: maintainer
PR 12/25 Blacksmith, returning-contributor fork 12/25 (identical), unknown
author 0/25, FIRST_TIME_CONTRIBUTOR 0/25, push to main 12/25 unchanged.
Guard tests gained trusted/untrusted fork cases; 119 pass.
Two pieces of dead workflow surface, found auditing where CI time goes:
- ci-timings-summary was hard-disabled (`if: ${{ false && ... }}`) with a
TODO to re-enable or delete it after the next timing-optimization
review. That review happened; the local `pnpm ci:timings` helper is what
we actually use, and docs already pointed there. The job carried a
25-entry needs list that had to be kept in sync to stay lintable.
- build-artifacts exported four `*-result` outputs that no job or workflow
reads.
Removing the job lets the gate guard assert the stronger invariant it
wanted all along: ci-gate needs *every* job in the file, so a new lane
cannot slip in ungated (28 jobs, 27 gated, zero exceptions).
No runtime behavior changes: the job could never run and the outputs had
no consumers. Also audited every `pnpm <script>` and `node scripts/...`
reference in ci.yml for rot -- all resolve.
build-artifacts is the wall's pole in 4 of the last 5 main runs (171-186s,
~15-20s ahead of the next lane), so its serial steps are the wall. The
Doctor plugin-index proof, singleton smoke, and startup-memory check ran
as their own 13s step even though they are independent dist readers that
the 47s artifact-check wave could absorb.
They now run inside that wave: on Blacksmith all seven start together, so
the verifiers cost the wave's max instead of 13s of serial time; hosted
runners still serialize the three through run_verifier so the RSS ceiling
measures an unloaded process. The step drops its selection gate because
the verifiers always run -- each artifact check already self-gates on its
own RUN_* flag, so a run with no checks selected still verifies.
Proof: extracted the step body and ran it with stubbed pnpm/node. Both
modes behave (Blacksmith 7 checks started, hosted-with-nothing-selected
still runs the 3 verifiers), and a failing verifier exits 1 with its
::error annotation in both -- the wave cannot swallow it.
checks-node-core-tooling-2 failed on main (run 31943910358) with
'expected 1786879225197 to be >= 1786879225197.2246': the repaired output
mtime landed a fraction of a millisecond below the input it had to clear.
isArtifactSetFresh repairs output mtimes to exactly ceil(newestInput), so
it leaves zero headroom for sub-millisecond write rounding or lagging
metadata on CI filesystems. When the repair lands at or below its input
the mtime fast path never engages, and every later invocation in that
checkout falls back to re-hashing every input byte -- the expensive path
this repair exists to avoid, gating the d.ts emit that is the slowest
build-all phase (25.9s of a 61s build).
Neither macOS APFS nor an idle Linux ext4 Testbox reproduces the
shortfall in 300 runs, so the repair now clears the newest input by a
whole millisecond instead of matching it. The assertion pins that
headroom, making the test deterministic where it was previously
load-dependent (fails 615 vs 616 without the fix).
* fix(ui): reset logs when source changes
Reload the active tail without a cursor when logs.tail switches files so the Control UI never mixes sources or skips a new file prefix.
* fix(ui): reset log source after reconnect
* test(ui): harden logs lifecycle proof
* test(ui): route Logs lifecycle through real Gateway lane
Pin OCM v0.2.32 so Performance validation uses upstream native .mts discovery and transitive workspace dependency handling instead of the local Bash/tsx trampoline.
* feat(workers): run device sessions from Gateway bundles
Install the current Gateway bundle before a device environment becomes ready, verify it at attach and tunnel boundaries, launch only from the immutable namespaced bundle directory, and retire stale environments for idempotent reprovisioning. Remove the local execution mode and preserve the node-local build claim only as temporary inventory metadata for the final projection/cleanup slice.
