SC6001 only looked at call arguments and typed initializers, and only at
strict field subsets: a target that adds optional properties, the empty
record type, `r as T`, a later `v = r` into a typed binding, and records
stored as elements of a typed array literal copied silently.
The scan now reports a copy whenever the property sets differ, covers
those sites, and reports a class instance that reaches a plain record
type which does not keep its identity (the remaining boundary: interfaces
of only generic methods). Every corpus program still reports no
divergence.
Deferred collection diagnostics now stay attached to their declaration until a
copy reaches the final report, so a discarded probe buffer or a successful
nested collection can no longer drop them. Uses of a binding whose type names
a rejected class report that class's diagnostic before the inherited-blocker
cascade.
- Preserve callback identity, receiver binding, and class references across unions and collections.
- Track record field presence independently of undefined values and improve native runtime behavior.
- Expand differential coverage and streamline CI bootstrap and compiler rebuild checks.
- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
* Expand static compilation for common Effect 4 patterns
* Run every Effect 4 fixture slice in CI
* Preserve existing corpus behavior across Effect 4 lowering
* Preserve Effect platform callbacks and native stream state
* Record new corpus baselines and retain child stdin refusals
* Retire the obsolete stateful regex diagnostic
* Preserve promise reference count layout for cycle collection
- Remove C emission, debugging options, and automatic backend fallback.
- Complete LLVM lowering and native bootstrap coverage across supported targets.
- Link executables and libraries with precompiled C runtime packs, including iOS and Android.
- Compile record predicates and class guards over array-derived values.
- Preserve missing-value checks and report unsupported union refinements.
- Cover narrowing in differential tests, coverage analysis, and frontend baselines.

* Reuse reachability lowering output
- Retain reachable IR and assemble the emitted module without lowering bodies a second time
- Preserve reached-only artifact filtering, coverage remainder behavior, and add lowering phase timing
* Preserve record order in retained lowering
* Preserve record order in retained helpers
* Preserve generic lowering record order
* Recheck retained generic rest order
* Record retained lowering parity fixtures
* Preserve retained lowering failure parity
- 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
