- Pin the supported fetch surface to an explicit Node and Undici profile.
- Generate deterministic WebIDL, AbortSignal, and stream differential campaigns.
- Match Node stream pull scheduling while preserving typed source identity.
- Add a custom Node 24 test image with tenant-neutral VCR configuration.
- Shard differential suites across disposable Sandboxes while preserving host-specific coverage.
- Load local agent credentials safely and document the validation workflow.
- packages/compiler/surface-manifest.json is generated (pnpm manifest), committed, and shipped in @scriptc/compiler; entries project mechanically from the diagnostics registry, the unsupported-syntax dispatch tables, the stdlib/builtin lowering tables, and the supported-builtin-module list
- every non-static entry carries the SC code the compiler raises for it, and the version spine is the exact published release version
- FENCE_CODES joins the diagnostics registry so factory-minted construct fences are enumerable
- the sampling harness compiles listed-static probes and asserts each sampled non-static entry refuses with exactly its listed code, beside a byte-identical staleness guard
- the release workflow regenerates the manifest, fails on drift, and attaches it to the GitHub release
