Sub-agent caching audit tranche, all measured on runs 31856622489 and
31857193681:
- QA Smoke parts rebuilt the runtime twice and packed a docker tgz that no
scenario in the smoke coverage set consumes (verified against the resolved
plan: zero docker-lane, zero Control UI scenarios). One private overlay
build replaces the public-build/ui:build/pack/private-rebuild chain
(~35-50s per part); the run step fails closed if a docker-lane scenario
ever returns, and the guard now pins never-pack-after-private-build.
- report-plugin-sdk-api-diff is pure reporting (nothing passes
--require-acknowledgement); it now runs on manual/release dispatches only.
- check-npm-lock resolved ~94 npm graphs against the registry on every push;
push/PR runs now use the reviewed --changed scoping (2.4s on dep-free
diffs) with a fail-open full sweep on base-fetch failure, and dispatches
keep --all for registry-drift coverage.
- Six restore-test-caches gates said 'github' only while the writer already
runs in hybrid; hybrid attempt-1 lanes now restore the transform seed.
- QA smoke lane reads the protected build compile cache; test-type stripes
widen to five.
Green tip run 31855637027 measured the remaining poles: ui-e2e shards up to
282s (imbalanced eight-way split), report-plugin-sdk-api-diff 246s on 4 vCPU,
and 220s test-type stripes (tsgo saturates a machine per graph, so stripe
count is the lever, not cores). Widen hosted-profile ui-e2e to ten rows,
test-type stripes to four, and lift the SDK diff to the 8 vCPU class.
First hybrid main cycles (runs 31850815388-31851455918) landed at 5:47-6:32
walls with every remaining pole a hosted lane: the three test-type stripes
(232-269s), check-additional-runtime-topology (274s), check-dependencies
(260s), and report-plugin-sdk-api-diff (209s). Route them to their Blacksmith
labels on hybrid attempt 1 (retries stay hosted) and lift runtime topology to
the 8 vCPU class.
* perf(ci): cut hosted CI critical path toward five-minute walls
Stripe the serial core test-type graphs across two hosted jobs and drop the
duplicated tsgo:test:root pass; gate the six-part QA Smoke matrix off pull
requests unless a QA-owned surface changed; split the fat multi-config Node
shards (cli/cli-process, unit-fast isolated/fake-timers, infra
logging-process/runtime-config) and lower the hosted split ceiling to 150
predicted seconds so no compact lane owns a ~280s wall; expand tooling to
seven stripes.
* perf(ci): widen hosted test-type striping to three jobs
Run 31825922122 measured ~40s per core test-type graph on loaded hosted
runners (282s worst stripe body of the two-way split); three stripes keep
each lane near 150s body under load.
* ci: codify manual-only Node 22 compatibility
* ci: split remaining hosted tail lanes
* fix(qa-lab): carry the validated part index into the plan id type
* test(ci): repair hosted tail lane guards
* ci: run push compacts without tooling lanes and stripe giants three-way
* fix(ci): keep CompactNodeTestPlanMode internal
knip --production flags the exported type as unused; no external module
imports it.
* ci: shard hosted lint and node tests
Split core oxlint across hosted runners and use backend-specific compact Node admission caps while preserving Blacksmith behavior.
* test(ci): guard plugin prerelease planner isolation
Measured canonical-main first-start delay: median 180s, average 209s; 10 of the last 30 runs waited more than 300s.
Approved tradeoff: up to ~+30 concurrent Blacksmith VMs during merge storms. Scope is canonical main pushes only; pull requests, manual runs, non-main refs, and forks keep their existing semantics.
Bump the canonical-main concurrency group from v7 to v8 so in-flight old-group runs cannot mix with the two-slot pipeline.
Run the built local TUI PTY lane after the other artifact checks so its real Gateway fixture has exclusive process and event-loop capacity.
Punchcard-Session: cobalt-brook-meadow-m9
* fix(tui): cancel buffered submissions on shutdown
* refactor(tui): preserve callable submit coalescer
* test(tui): run local PTY smoke against built CLI
