P1 Badge Install the Node oracle before testing the workspace

On the clean quality runner, cargo test --workspace includes bamts-verification/tests/corpus_differential.rs, whose non-ignored tests require the exact pinned Node version and invoke node_modules/.bin/tsc. This job has neither a setup-node step nor npm ci, so those tests fail because the TypeScript executable is absent (and the hosted runner's Node is not guaranteed to be v24.18.0), preventing the new CI workflow from completing even though the separate corpus job performs the required setup.

P1 Badge Classify the suite before selecting included cells

On every clean Actions checkout, the repository has no verification/ts-suite-ledger.json because that file is ignored, and sync writes only the provisional ledger, where all compiler facets are Deferred. The subsequent ci --status included invocation therefore plans zero cells and exits successfully, so all four PR conformance shards—and the equivalent nightly shards—can pass without checking any TypeScript case; use the classification path or provide the classified ledger before running these shards.

The boundary fixture tree is untracked and never generated. .gitignore declares perf/fixtures/boundary/ as a generated artifact, and no workflow step produces it before perf_budget verify-fixtures consumes it. On a clean runner the directory does not exist.

  • .github/workflows/ci.yml#L291-L294: add the fixture materialization command before the Verify fixtures step, or prove that perf/benchmarks.toml references only committed upstream bytes.
  • .gitignore#L8: keep the ignore rule only if a generator step exists; otherwise commit the boundary fixtures as pinned artifacts alongside perf/fixtures/upstream/.

P1 Badge Materialize the suite in the performance job

On a clean BH1 runner, this measurement fails before collecting any result because the perf-bh1 job never runs ts_conformance sync or downloads the snapshot created by preflight; GitHub jobs do not share their worktrees, and checkout cleans the ignored verification/ts-suite directory. perf_budget measure immediately calls run_suite_with_telemetry, which requires files such as verification/ts-suite/oracle/pin.json, so the newly required performance job cannot succeed unless it happens to inherit stale runner state.

P1 Badge Compare candidate measurements with the TypeScript scorecard

In the checked perf-bh1 workflow, check-scorecard only validates the committed upstream scorecard's schema, host, and positive quantiles; it never reads target/perf/pr-s0.json or computes candidate/upstream ratios. The S0 baseline also has no release block, so compare skips the policy's release thresholds, allowing a candidate that is arbitrarily slower than TypeScript to pass this advertised comparator gate.
