…(gate-audit R1) Every plain cargo-test shape reports all failures in one run; the group loop runs every suite before exiting non-zero. The required aggregator now renders actual failing test names (from nextest's JUnit output, wired by Tasks 3-5) instead of a job-status table the Checks UI already shows. Leaves the coverage arm (:404) and the two crate-tests cargo-test arms (:417-419, :427-428, converted to nextest in Task 4) untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…tegration) Worker-stress constraint keeps this well under the queue's 14/4/5. No new in-workflow gate: the changes planner already fronts every job, and a serial lint gate would cost every PR ~2 min to save minutes only on trivially-red pushes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ot partitions on nextest
scripts/ci/lib/select-test-runner.sh replaces quality_gate.sh's inline
copy and is the ONE thing every CI runner script sources (policy
require-in-ci) -- no second implementation. IRONCLAW_GATE_TEST_RUNNER now
crosses the hermetic wrapper's env allowlist. test-hermetic-test-process.sh
gets a real negative control: a nextest-run test that must be blocked by
the network guard when active and must NOT be blocked when sabotaged,
proving the guard applies to nextest's own child-process spawn path (the
prior file-scanning self-test never invoked cargo or nextest at all). Root
partitions swap to cargo-nextest --profile ci: behavior-identical
(equivalence proof in PR body), same tests, same partitioning.
Empirically, scripts/ci/hermetic-network-runner.sh forces its own exit
code to 86 whenever any non-loopback attempt is logged, even one the
guard's interposer correctly blocked with EPERM -- so the negative
control's pass/fail signal is the test's own reported outcome in
nextest's captured output ("... ok" vs a PermissionDenied-mismatch
panic), not the wrapper's process exit code.

… repro matches Both non-coverage arms of the crate-tests "Run crate tests" step (the per-exact-target loop and the bulk-package invocation) swap cargo test for cargo nextest run --profile ci, keeping per-package feature flags, the RUSTC_BOOTSTRAP/-Zcrate-attr env, CARGO_INCREMENTAL=0 for ironclaw_composition, and the hermetic prepare-command/command wrappers untouched. The coverage arm (line 404's cargo llvm-cov invocation) is byte-identical -- this task does not touch it (Decision 2). scripts/ci/run-hermetic-deterministic-suite.sh's run_crate_tests (the canonical local full-workspace reproduction, never invoked from a workflow) now routes through the same scripts/ci/lib/select-test-runner.sh seam Task 3 introduced, closing the local/CI parity gap the nextest swap would otherwise have widened. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…roup mode stays on cargo The uninstrumented (REBORN_COV_COLLECT=false) else-arm of reborn-coverage-lane-run.sh swaps cargo test for cargo nextest run --profile ci in flat-partition mode. group mode gets an explicit code-level carve-out (Decision 3): it forces runner=cargo regardless of what select_test_runner would otherwise pick, since this mode selects the identical reborn_group_* set as the dedicated group job, and that job's whole purpose is keeping those binaries out of a cross-binary-concurrent pool. Verified end-to-end in scripts/ci/test-quality-gate-runner.sh with a stubbed cargo-nextest present on PATH to prove it is ignored. The instrumented (REBORN_COV_COLLECT=true) coverage arm is untouched (Decision 2). run_integration_tier in run-hermetic-deterministic-suite.sh (the canonical local full-tier reproduction) now routes through the same runner-selection seam; unlike the lane script it does not split group vs. flat (a deliberate, narrower scope difference documented inline, since this local function's scope was always "the full tier" rather than "one lane"). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…s this plan touches Root-partition, group-tests, integration-lane, and crate-bucket steps each set REPRO to the exact reproducing command, persist it to $GITHUB_ENV before executing, then eval it (root-partition, group-tests, crate-bucket) or run the step's own real invocation unchanged (integration-lane, where REPRO is a PR-path-only reproduction distinct from the step's actual REBORN_COV_COLLECT-conditional command). A fixed "Local repro for this job" step renders whatever $GITHUB_ENV holds on failure, identical text across every job so it cannot go stale on a rename. Cites T4's Task 4 Interfaces (scratchpad/plans/T4-canonical-preflight.md) as the pattern's source, re-verified directly against that plan file since T4 has not merged yet. The crate-bucket REPRO strings include the timeout wrapper and incremental_env prefix (CARGO_INCREMENTAL=0 for ironclaw_composition) that actually ran, not just the bare nextest invocation, since eval'ing a stripped-down REPRO would silently change what runs. This also updates two of Task 4's own pinned test literals, which this task's REPRO edit supersedes at the same lines. The integration-lane step's REPRO targets the uninstrumented PR/queue reproduction only; the coverage arm (push-to-main-only, byte-identical per Decision 2) is out of scope regardless. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…-model-dependent scripts/ci/check-hermetic-env.sh's lock_env()/EnvGuard requirement was written for cargo test's thread-per-test model; cargo nextest (now wired for root partitions, crate buckets, and uninstrumented integration lanes) runs one process per test, so the cross-test race the guard exists to prevent cannot occur the same way there. Leaves the check itself unchanged -- documentation only, so nobody deletes the guard believing it is now dead weight everywhere. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Upload JUnit report step, retaining only the value ignore so missing nextest
JUnit output does not fail coverage runs.
- Around line 883-888: Update the REPRO assignment near the coverage-lane

- Around line 421-433: Update the nextest invocations in both the exact-target

remaining targets. Accumulate any failure status across invocations and exit

parsing, or explicitly reject DTD/entity declarations and enforce a maximum
JUnit report size before ET.parse. Preserve the existing list[FailedTest] output
while ensuring oversized or entity-expanding PR-controlled XML is rejected
safely.
In `@scripts/ci/run-hermetic-deterministic-suite.sh`:
- Around line 81-82: Update both caller paths invoking select_test_runner in
run-hermetic-deterministic-suite.sh to use require-in-ci, preserving local Cargo
fallback when CI is unset. Add a regression test covering each caller with
CI=true and cargo-nextest unavailable, asserting the path fails rather than
selecting Cargo.
In `@tests/hermetic_network_guard_probe.rs`:
- Around line 8-12: Update the hermetic guard scenario description near the test
documentation to state that the guarded connection must produce
PermissionDenied, while the sabotaged run must produce any outcome other than
PermissionDenied. Remove the incorrect connection-refused wording without
changing the test behavior.

Review · Summary
Found a workflow shell-injection path and two low-severity test-maintenance gaps.
Findings: 🔴 High 1 · 🟡 Low 2
Code-specific findings are attached to the diff. General findings are shown below.
🟡 Low · Run the JUnit-summary regression test in CI
The new test_junit_summary.py is not invoked by any checked-in workflow. The static CI self-test step enumerates individual scripts but omits this one, so future parser regressions can merge without its regression cases running. Add it to the relevant CI self-test step.
Validation
- ✅ Focused CI checks — Runner-selection checks, JUnit-summary regression cases (3), Reborn PR-plan tests (87), and test-suite boundary checks passed.
- ✅ Shell syntax — All changed Bash CI scripts passed syntax validation.

Code Review (multi-agent)
Intent: Speed up CI tests with nextest, fuller failure reporting, modest parallelism, hermetic runner selection, reproducible commands, and preserved test/check contracts.
Stats: 4 findings (from 7 raw, 4 after filter, 4 after dedup) across 3 files. Reviewers run: correctness, security, performance, design, coverage. Reviewers failed: none. Body-only: 2. Repository reconnaissance evidence: degraded because the exact-head checkout was a tarball without the repository graph; direct source and contract inspection completed.
Bugs
-
High Coverage lanes fail while uploading a nonexistent JUnit report (
.github/workflows/reborn-tests.yml:907-914, confidence 99) — anchor:.github/workflows/reborn-tests.yml:914(no diff position — body only). The JUnit upload always runs when coverage usescargo llvm-cov, which does not createtarget/nextest/ci/junit.xml; the duplicateif-no-files-foundkeys resolve toerror, so successful coverage lanes fail during artifact upload. Also flagged by coverage/High. Fix: Keep a singleif-no-files-found: ignoreentry, or condition the JUnit upload onREBORN_COV_COLLECT=false. -
Medium Failing crate invocations never copy their JUnit report (
.github/workflows/reborn-tests.yml:421-424, confidence 98) — anchor:.github/workflows/reborn-tests.yml:423(no diff position — body only). With shell errexit, a failingevalexits before the followingcp, so the report for the failing exact-target invocation is omitted and the roll-up misses the primary failing tests. Also flagged by design/Medium. Fix: Capture the eval status, copyjunit.xmlunconditionally, then return the captured status.
Approach
- Medium Local integration reproduction sends group suites through nextest (
scripts/ci/run-hermetic-deterministic-suite.sh:101-106, confidence 94) — anchor:scripts/ci/run-hermetic-deterministic-suite.sh:101. Integration discovery includesreborn_group_*, while CI explicitly forces group mode to cargo because those binaries must remain sequential; the local canonical reproduction can therefore reintroduce the known shared-store concurrency failure. Candidate — validate claim. Fix: Route group suites through the dedicated sequential group runner or exclude them from this nextest path.
Tests
- Medium Full-failure group aggregation lacks an executable regression test (
scripts/ci/run-reborn-group-tests.sh:49-57, confidence 92) — anchor:scripts/ci/run-reborn-group-tests.sh:49. No self-test proves that a failing group continues to the next suite and exits nonzero afterward, so a future fail-fast regression could pass current checks. Candidate — validate claim. Fix: Add a runner-contract test with multiple controlled binaries covering continuation, per-suite reporting, and final nonzero status.

Higher is better. 85+ clean · ~60 one loose end · ≤40 a critical defect caps the axis. I'd approach this differently. If I were building this, I’d start from the canonical The strongest parts are the places where the change respects existing ownership:
How I read this changeI traced the change from workflow matrix steps through the shared selector, hermetic wrapper, nextest profile, artifact uploads, and local reproduction paths. I expected every runner choice to converge on the new selector and every diagnostic path to distinguish missing evidence from a clean run. The root and integration paths mostly follow that shape, but the crate-test workflow hardcodes nextest and the reporting/reproduction paths suppress or alter important execution details. That leaves the migration’s central policy and its failure signal inconsistent across lanes. Right-shape sketchThis is a shape sketch, not a patch: keep workflow YAML as matrix plumbing, route crate-test execution through the existing hermetic/script path that sources flowchart LR

Rule revisitWorth changing: require every new |
The control added earlier in this branch shells out to `cargo nextest`, which runs `cargo metadata` under the hermetic wrapper. `fast-checks` is deliberately a cache-less, toolchain-light lane, so that resolution had no warm registry and failed offline with "no matching package named `async-trait` found" — reddening `Fast deterministic checks` and the required `Code Style (fmt + clippy)` roll-up on this PR. On main this self-test invokes cargo zero times; the regression was putting a cargo-dependent check into the one job built to avoid cargo. The control is now opt-in via IRONCLAW_HERMETIC_NEXTEST_CONTROL=1 and runs in root-reborn-parity-tests, which already installs the toolchain and cargo-nextest, restores the registry cache, and builds the probe crate. The default path runs exactly the stub-based checks main runs. This also closes an ordering hazard that would have bitten anyway: the `all` stage of run-hermetic-deterministic-suite.sh invokes this self-test *before* prepare_rust_dependencies, so the control could never have resolved there. Regression test: scripts/ci/test-hermetic-nextest-control-gating.sh pins both halves of the contract in a PATH sandbox — the default run must exit 0, must report the control as skipped, and must never invoke cargo (a stub records any invocation); an opted-in run without cargo-nextest under CI must still fail loudly. Proven red-first: with the gate removed it reports 3 failures including the recorded cargo call, and passes once restored. Wired into the fast-checks self-test list beside the script it guards. Verified: ws12 self-tests 94 OK; ws12 live gate passed; planner suite 87 OK; both workflows parse. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- preserve canonical setup-rust ownership while retaining nextest/JUnit coverage - combine workflow safety regressions from both branches - address fresh review findings for selected group tests and shell/YAML guards

Read and cross-checked the T1 scheduling handoff against the synchronized head.
I will use the current run timing and job-start profile as the final scheduling evidence rather than claiming improvement from per-test runtime alone. |
The root package build invokes the WebUI build script, so warm both Cargo and pnpm dependencies before the network guard closes external access.

The control and probe run in separate workflow processes, so give the root job the same caller-owned Corepack home as the other guarded Rust lanes and pin its presence/order with workflow contracts.
Reject both dot-property and quoted bracket references when planner-derived matrix values would enter root-test shell source.

Code Review (multi-agent)
Intent: Optimize the Tests (Reborn) CI pipeline with nextest, fuller failure reporting, controlled parallelism, hermetic runner selection, and local/CI parity.
Stats: 10 findings (from 10 raw, 10 after filter, 10 after dedup) across 10 files. Reviewers run: correctness, security, performance, design, coverage. Reviewers failed: none. Body-only: 2
Bugs
-
Medium Standalone stages no longer prepare frontend dependencies (
scripts/ci/run-hermetic-deterministic-suite.sh:42-43, confidence 90) — anchor: scripts/ci/run-hermetic-deterministic-suite.sh:42
Removing prepare_frontend_dependencies from prepare_rust_dependencies leaves the standalone crates and integration stages without frontend setup. A local invocation of either stage enters the hermetic offline environment and can fail when a package build script invokes the WebUI's pinned pnpm toolchain, breaking the documented local/CI parity contract.
Fix: Prepare frontend dependencies in every standalone stage whose Rust dependency graph can build the WebUI, or retain that preparation in prepare_rust_dependencies. -
Medium Coverage lanes upload non-nextest JUnit reports (
.github/workflows/reborn-tests.yml:916-926, confidence 85) (no diff position — body only) — anchor: .github/workflows/reborn-tests.yml:923
When run_coverage is true, the integration coverage lane runs cargo llvm-cov, not nextest, but these unconditional staging and upload steps still copy target/nextest/ci/junit.xml. If the shared target cache contains an older report, the aggregator can display failures from a previous invocation; otherwise it uploads no useful report while presenting the artifact as a current lane report.
Fix: Guard JUnit staging and upload with needs.changes.outputs.run_coverage != 'true', or remove any stale report before the coverage command and only upload a report produced by nextest.
Maintainability
- Medium Workflow validation bypasses its supplied workflow snapshot (
scripts/ci/ws12_workflow_contracts.py:2010, confidence 96) — anchor: scripts/ci/ws12_workflow_contracts.py:2010
validate_workflow_texts(workflows, root) now calls validate_no_duplicate_yaml_keys(root), which rereads live workflow files instead of validating the supplied workflows mapping. This breaks the existing composable sabotage-test pattern and makes the validator depend on hidden filesystem state.
Fix: Pass the loaded workflow texts into the duplicate-key checker, or make the checker operate on one explicit source, so all contract checks inspect the same snapshot.
Tests
-
Medium Add caller-level coverage for the nextest root-partition path (
scripts/ci/run-reborn-root-partition.sh:60-67, confidence 91) — anchor: scripts/ci/run-reborn-root-partition.sh:60
The root partition runner changed from invoking each selected test separately to one nextest invocation with multiple --test arguments, but the changed tests only assert workflow source strings. A regression in partition selection or argument forwarding could silently omit or misroute root tests without detection.
Fix: Add a runner test with a stubbed cargo-nextest covering a multi-test partition and the cargo fallback, asserting the exact selected tests. -
Medium Cover the flat uninstrumented coverage lane's nextest branch (
scripts/ci/reborn-coverage-lane-run.sh:150-158, confidence 88) — anchor: scripts/ci/reborn-coverage-lane-run.sh:151
The new flat-partition path selects nextest in PR coverage lanes, but the added end-to-end test only exercises the group-mode cargo carve-out; existing hermetic runner coverage does not call reborn-coverage-lane-run.sh.
Fix: Add a test covering flat mode with nextest present and absent, asserting selected --test arguments and cargo fallback.

Closing this implementation because the exact-head Tests (Reborn) run took 38m42s from workflow creation to the required roll-up, against T2’s goal of roughly 10 minutes including queue time. The 6/2/2 admission shape still creates matrix waves, and the approach audit found that crate buckets bypass the canonical runner-selection/rollback seam. The nextest, JUnit, hermetic-control, and full-failure-signal pieces remain useful inputs for a narrower redesign. Keeping #7799 open to track the replacement design and measured end-to-end acceptance criterion. |
Closes #7799
Summary
Cuts the
Tests (Reborn)workflow's wall clock and gives every red run full-failure signal (all failing test names, not just the failing job), without changing which tests run, which checks are required, or the local optional-nextest contract.Layer by layer:
cargo testshape (sandbox steps, QA replay, the group loop) gains--no-fail-fast. Thereborn-testsaggregator gets a new step-summary roll-up (scripts/ci/junit_summary.py+ self-test) that downloads every nextest job's JUnit report and renders actual failing test names + first failure line — a job-status table adds nothing GitHub's Checks UI doesn't already show, so this renders per-test failures instead.max-parallelraised 3→6 (crate buckets), 1→2 (root partitions, integration lanes) — still well under the queue's 14/4/5. No new in-workflow gate: thechangesplanner already fronts every job.scripts/ci/lib/select-test-runner.shreplacesquality_gate.sh's inline copy and is the only thing every CI runner script sources (optionallocally,require-in-ciin CI: nextest when installed, a hard loud failure if missing underCI=true, never a silent 3x-slower fallback).IRONCLAW_GATE_TEST_RUNNERnow crosses the hermetic wrapper's env allowlist (the bisect knob: forcecargoeven in CI).tests/hermetic_network_guard_probe.rs+ an extendedscripts/ci/test-hermetic-test-process.shprove nextest's own per-test child-process spawn path — not just a directly-launched probe — inherits the hermetic network guard. Root partitions swap tocargo nextest run --profile ci.cargo llvm-cov) is byte-identical. The canonical local reproduction (run_crate_testsinrun-hermetic-deterministic-suite.sh) now routes through the same seam, closing a pre-existing local/CI parity gap.reborn-coverage-lane-run.shswaps to nextest;groupmode gets an explicit code-level carve-out forcingrunner=cargoregardless of nextest availability, since it selects the identicalreborn_group_*set as the dedicated group job (kept sequential — PR fix(filesystem): pool libSQL connections to stop concurrent-CAS SQLITE_MISUSE (#5466) #5751's documented libsql SIGABRT history).run_integration_tier's local reproduction is likewise routed through the seam.REPRO=→$GITHUB_ENV→eval, plus one fixed "Local repro for this job" step) into the four job types this plan touches, so a red run's own job summary carries the exact reproducing command..claude/rules/testing.mdgets one paragraph:lock_env()/EnvGuard's cross-test race rationale is specific tocargo test's thread-per-test model; under nextest each test is its own process, so the same race cannot happen the same way — noted so nobody deletes the guard as "now redundant" for the wrong reason.timeout-minutesin this PR; the exact measurement commands and theceil(p90 × 1.5)procedure are recorded below as the literal next step once this PR has soaked.Track C note
This is a CI change: needs 2 approvals. Rollback Plan is below, copied per the plan's Track C ceremony.
Deviations from the plan (each re-verified against the live worktree; none rejected)
Task 3's negative-control invocation was missing
-p ironclaw_integration_tests. Root-level tests aren't selected by a barecargo test/cargo nextest runwithout-p/--workspace; empirically confirmed (cargo nextest list ... --test hermetic_network_guard_probefailed with "no test target named ... in default-run packages" until-pwas added). Fixed in both the guarded and sabotaged invocations.Major deviation — the negative control's actual PASS/FAIL signal. The plan asserted the guarded run must exit status 0. Empirically wrong:
scripts/ci/hermetic-network-runner.shforces its own exit code to 86 whenever any non-loopback connection attempt is logged — even one the guard's interposer correctly blocked with EPERM. Verified end-to-end locally: the guarded run exits 86, but nextest's own captured stdout showstest nextest_child_process_is_network_guarded ... ok/1 passed(the interposer's EPERM satisfied the test'sassert_eq!(err.kind(), PermissionDenied, ...)); the sabotaged run panics withassertionleft == rightfailed: ... left: TimedOut, right: PermissionDenied(a genuine ~5s timeout to the unroutable TEST-NET-1 target). Fixed the self-test to assert on the captured output text instead of the process exit code — this is the stronger, actually-correct proof, since it directly exercises the interposer's EPERM behavior rather than an exit code that happens to be wrong for a coincidental reason.Task 8's crate-bucket REPRO snippet dropped the
timeoutwrapper and${incremental_env[@]}prefix from the string that getseval'd to actually execute the test. Since Pattern B executes viaeval "${REPRO}", this would have silently removed the 28-minute per-invocation timeout backstop and theCARGO_INCREMENTAL=0override forironclaw_composition— a real behavior change hidden inside a task documented as job-summary-only. Fixed by including both in the REPRO string, soeval'd behavior is byte-for-byte unchanged; this also required updating two of Task 4's own pinned test literals intest_reborn_pr_test_plan.py(the REPRO string flattens"${arr[@]}"to${arr[*]}), done in the Task 8 commit.Task 5's group-mode carve-out self-test had no exact snippet in the plan. Implemented as a real functional test in
scripts/ci/test-quality-gate-runner.sh: sandboxesreborn-coverage-lane-run.shwith stubbedcargo/cargo-nextestand a stubbed suite-discovery script, assertingREBORN_COV_LANE_MODE=groupalways invokescargo test, never nextest, even withcargo-nextestpresent. Also ran the plan's own live check through the real hermetic wrapper:GROUP-MODE-CARVEOUT-HOLDSconfirmed.T4's Task 4 (Pattern B) has not merged yet. Task 8 implements Pattern B exactly as specified in
T4-canonical-preflight.md's Task 4 Interfaces, re-verified directly against that plan file (matches what this plan quotes verbatim). Landing/rebase sequencing with T4's actual merge is a merge-queue concern, not a blocker for authoring these commits.Environment-only, not a code change: this shared dev host ran several sibling CI-expedite-lane agents concurrently (8 cores / 22 GB RAM), which OOM-killed one full-workspace verification build; retried with a temporary, uncommitted
[build] jobs = 2cap (reverted before every commit, never landed). Also hit a local-only Node/corepack version mismatch building the WebUI frontend inside the hermetic sandbox (ERR_VM_DYNAMIC_IMPORT_CALLBACK_MISSING); fixed locally vianpm install -g corepack@latest— a sandbox tooling defect unrelated to this PR; CI's own pinnedactions/setup-nodetoolchain is unaffected.Post-merge measurement follow-up (Task 6 — not part of this PR)
Record new PR p50/p90, slowest job, slowest step. Then the root-partition job's compile-vs-execute split (the number the deferred consolidation families' 40%-compile-share threshold is gated on):
If
compile_time / total_step_time≥ 40% on ≥2 of 3 sampled partitions, open a follow-up consolidating the deferred trace-parity (12 files), QA-phrase (6), and binary-e2e (2) families, reusing the#[path]recipe from the scope-isolation consolidation probe (separate stacked PR). Otherwise, investigate--partition hash:N/Msharding instead of further consolidation. This measurement must land before Task 10'stimeout-minutespin (below).Task 10 — budget pin (scaffolded, deferred to post-soak)
Not executed in this PR (no measured data exists pre-merge). Once ≥1 week / ≥20 PR runs / ≥10 merge_group runs have landed on
main:# same commands as the Task 6 measurement above, computing per-job p90Then set each PR-path job's
timeout-minutestoceil(p90 × 1.5)(crate-testscurrently 90,root-reborn-parity-tests45,reborn-group-tests110,reborn-integration-coverage120) — never below the coverage-instrumented budget for jobs that also serve push runs; prefer${{ github.event_name == 'push' && X || Y }}so PR-path hangs die fast without shrinking the push-path budget.Rollback Plan
Each task is one revertible commit; none changes persisted state, schemas, or the plan JSON contract (planner output fields are unchanged throughout — in-flight PRs keep working against either side of every commit).
Partial-degradation option without a revert: every nextest-driven runner script falls back to sequential
cargo testwhenevercargo-nextestis absent from PATH, butrequire-in-cipolicy makes that a hard failure onceCI=true. To soft-disable nextest instead of reverting, setIRONCLAW_GATE_TEST_RUNNER=cargoas a job-level env var (or repo-level Actions variable) — every runner script sourcingscripts/ci/lib/select-test-runner.shhonors the explicit override before ever checkingcommand -v cargo-nextest, reverting every job to the pre-Task-3 sequential shape without touching any file.Compatibility: no plan-schema change; no required-check rename; queue/push behavior unchanged except job-internal runner choice and (Task 2) matrix concurrency; coverage lanes byte-identical including the
testtail aftercargo llvm-cov;merge_groupstill runs the full plan; group suites never enter the nextest pool (dedicated job or coverage-lanegroupmode). Follow-up risks: nextest's per-test process model can surface latent cross-test coupling as new failures (treat as findings, fix via[test-groups]serialization, never by editing tests); leak-detectionLEAKwarnings may appear in logs without failing runs; the 3 deferred consolidation families remain as 20 standalone root binaries pending the Task 6 threshold measurement.Cross-track
T1 owns every "Install Rust" step swap (composite action); this PR's
Install cargo-nexteststeps are added immediately after each job's Install Rust step and are line-disjoint from it — on rebase, take T1's side on any Install Rust conflict and reapply this PR's edits on top.origin/mainhas moved substantially since this branch was cut (unrelated upstream work, including a repo-wide guidance-doc consolidation) — the three-dot diff against the actual merge-base is clean and scoped to the 17 files this PR touches; a rebase before merge is expected per the stated landing order (this lane lands second, after T1).Test Strategy
