Compile-smoke distributes top-level TypeScript test files across four stable shards, with at most two running concurrently. CI checks shard selection, and compile-smoke jobs use shard-specific artifact names. ChangesFull-tier CI sharding

Merge Risk: 🟡 Moderate · up to Compile-smoke selection failures are not silently ignored. However, GC evidence uploads from multiple shards can still conflict and fail the full-tier gate even when tests pass; fix the artifact naming before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The sharding design is bounded and validates selections before starting compile work. No concrete security regression was established. Remaining uncertainty concerns inherited CI privileges, the exact baseline comparison and current-head execution under cancellation or partial failure.

Give each GC evidence artifact a shard-specific name.
Each new matrix cell runs run_memory_stability_tests.sh with PERRY_GC_EVIDENCE_DIR set. The script creates a log in that directory. The unchanged upload step names every artifact gc-evidence-Linux, so uploads after the first fail with an artifact-name conflict. Those failures make the compile-smoke matrix and full-suite-gate fail even when the tests pass. Add ${{ matrix.shard }} to the GC evidence artifact name, as the error-log upload already does.

Full-tier checks are timing out while useful compile work is still running. At #11735's unchanged head, full gap shard 1 reached 137 of 152 tests before its 110-minute job limit; the unsharded compile-smoke job reached the hosted six-hour limit with native compiles still active. Re-running those same allocations does not address the missing time budget.
Distribute the full gap corpus over twelve auto-optimize shards instead of eight. Split all top-level compile-smoke TypeScript files into four stable round-robin shards, running at most two smoke shards concurrently. Keep the existing compile worker, default auto-optimize invocation, exclusions, retries, failure markers and matrix fan-in. Give each shard a distinct error-log artifact name. Invalid or empty shard selections fail before emitting a partial scope.
Local selection validation: planner invariants pass; smoke selector positive/negative controls pass; all 2,067 current top-level files are assigned exactly once across 517/517/517/516 files; the compile worker is byte-identical to main. Generated tier documentation matches the planner, and all seven existing Cargo test-scope tests pass. This proves selection and wiring, not new full-tier completion times. Full local script lint at
dfdc852664948369bc2f97f56c0cd8c8b887d4f6finished with 111 of 112 checks passing; only Public benchmark evidence freshness failed. The compile tier and two CI-only commands were explicitly skipped. Current head7e0a9c919219b25c0a3e57180bb534b78894c238includes the landed GC diagnostic timeout and provider preflight repairs. The second main merge is limited to the three reviewed #11741 files; all eleven provider setup protocol controls, planner invariants and selector controls pass at this head. Actual current-head workflow CI remains required before landing.The underlying compiler/runtime tests and acceptance thresholds are unchanged. Timeout ceilings remain in place, and a failed or cancelled shard still fails the aggregate job.
Summary by CodeRabbit
A full-tier workflow dispatch at the current branch head is being requested to validate the actual twelve gap shards and four compile-smoke shards. Local scope checks do not establish hosted completion time.
Actual full-run timing at current head
7e0a9c919219b25c0a3e57180bb534b78894c238: gap shard 5 and gap shard 2 completed successfully in 80.03 and 86.52 minutes, within the unchanged 110-minute job limit. Their snapshot gates accepted the original fixtures and known mismatches. Ten remaining gap shards and all four compile-smoke shards are not yet proven complete; this is partial timing evidence, not full-suite approval.Current-head timing blocker: gap shard 3 and gap shard 4 were cancelled at the unchanged 110-minute whole-job limit after 79/102 and 82/102 completed fixtures. Twelve shards are therefore not sufficient for acceptance. A local follow-up prepares 24 shards: all 1,216 gap fixtures are assigned exactly once, 50–51 per slice, and each old slice is exactly the union of two new slices. The worker, auto-optimize path, snapshot gate and timeout are unchanged. Planner self-tests and generated documentation checks pass; final-head lint and new hosted timing remain pending, and this follow-up is not yet pushed.
Terminal timing audit for the published twelve-shard head
7e0a9c919219b25c0a3e57180bb534b78894c238: all twelve gap jobs finished. Shards 1, 2 and 5 succeeded in 98.67, 86.52 and 80.03 minutes; the other nine were cancelled at 110.28–110.55 minutes. The four smoke jobs remain active or queued. No cancelled gap job is accepted. The unpublished 24-shard follow-up is now refreshed against mainb8a44f333e801d9e41a15cffe264d14280597c04atba570166d364440330a7d183e5b8b2d716e611c2; all Rust sources and Cargo metadata match that main exactly. Final-head local lint/product validation and hosted 24-shard timing remain pending.
