- Shard portable coverage across 16 sandboxes while retaining focused Darwin contracts.
- Run invariant suites once and keep differential and sanitizer-sensitive coverage in both lanes.
- Harden sandbox transport, exit-status parsing, and Linux runtime test portability.
- workspace-linked untyped dists register before the tsc gate and take the node_modules-JS island treatment (errors suppressed, out of userFiles)
- bare '.' and '..' specifiers resolve as relative directory imports (corpus 2386, coverage fixture dot-parent, SEMANTICS 362)
- TS default imports of supported builtins pass under the project's adopted interop knobs (corpus 2387)
- benign-cycle admission accepts d.ts-rooted callable arguments — promisify(fs.readFile) at a cycle member's top level (SEMANTICS 363)
- --npm-static auto probes runtime JS from the importing file's realm, not the entry's (nested-realm fixture)
- A type-error stop prints the same code frames a build prints
- The import-site stop renders its diagnostics below the blocker table
- Coverage is the first command reached for; the verdict line alone swallowed the fix
