# Beta23 Release Review

Verdict: PASS with notes.

## Findings

No blocking or non-blocking findings in the reviewed scope.

## Scope Reviewed

- `scripts/render-stdlib-api-doc.js` tier rendering.
- `scripts/check-stdlib-api-tiers.js` tier gate.
- `scripts/release-gate.sh` integration.
- Generated `docs/language/STDLIB_API.md`.
- `docs/language/STDLIB_TIERS.md`, README, release notes, roadmaps, and spec updates.
- Compiler package version bump and compiler release documentation.

## Acceptance Checklist

- PASS: `docs/language/STDLIB_TIERS.md` defines the public tier labels and explains the current beta meaning. See `docs/language/STDLIB_TIERS.md:21` through `docs/language/STDLIB_TIERS.md:25`.
- PASS: The tier ledger marks JSON, loopback networking, random/time, and filesystem resource-handle helpers as experimental domains. See `docs/language/STDLIB_TIERS.md:46` through `docs/language/STDLIB_TIERS.md:49`.
- PASS: The tier ledger records concrete vector modules as beta-supported concrete lanes without claiming generic collection stability. See `docs/language/STDLIB_TIERS.md:44`.
- PASS: The generated API catalog emits tier metadata and summary counts. See `docs/language/STDLIB_API.md:6` through `docs/language/STDLIB_API.md:24`.
- PASS: Generated catalog classification matches the beta23 contract: filesystem handle helpers are experimental in `docs/language/STDLIB_API.md:115` through `docs/language/STDLIB_API.md:119`; `std.json`, `std.net`, `std.random`, and `std.time` are experimental in `docs/language/STDLIB_API.md:195` through `docs/language/STDLIB_API.md:240`, `docs/language/STDLIB_API.md:294` through `docs/language/STDLIB_API.md:308`, `docs/language/STDLIB_API.md:425` through `docs/language/STDLIB_API.md:432`, and `docs/language/STDLIB_API.md:540` through `docs/language/STDLIB_API.md:547`.
- PASS: Concrete vector modules retain explicit no-generic-collection-freeze notes in generated output. Representative coverage is `docs/language/STDLIB_API.md:549` through `docs/language/STDLIB_API.md:554`, with the same note repeated for the other concrete `std.vec_*` modules.
- PASS: The renderer implements the tier map and emits per-module/per-helper tiers. See `scripts/render-stdlib-api-doc.js:12` through `scripts/render-stdlib-api-doc.js:46`, `scripts/render-stdlib-api-doc.js:245` through `scripts/render-stdlib-api-doc.js:263`, and `scripts/render-stdlib-api-doc.js:297` through `scripts/render-stdlib-api-doc.js:330`.
- PASS: The tier gate checks stale wording, summary tier definitions, experimental module/helper coverage, and vector boundary notes. See `scripts/check-stdlib-api-tiers.js:47` through `scripts/check-stdlib-api-tiers.js:80`.
- PASS: `scripts/release-gate.sh` runs syntax checks for both tier scripts and executes the tier checker after catalog rendering. See `scripts/release-gate.sh:12` through `scripts/release-gate.sh:16`.
- PASS: README, `lib/std/README.md`, language release notes, language roadmap, post-beta roadmap, and v1 spec link or describe the tier ledger and non-scope. Representative references: `README.md:69` through `README.md:79`, `lib/std/README.md:174` through `lib/std/README.md:184`, `docs/language/RELEASE_NOTES.md:53` through `docs/language/RELEASE_NOTES.md:69`, `docs/language/ROADMAP.md:109` through `docs/language/ROADMAP.md:119`, `docs/POST_BETA_ROADMAP.md:121` through `docs/POST_BETA_ROADMAP.md:132`, and `docs/language/SPEC-v1.md:268` through `docs/language/SPEC-v1.md:279`.
- PASS: Documentation states beta23 is documentation/catalog tooling clarity only and does not add language, stdlib, runtime, stable schema, ABI/layout, or stable API behavior. See `docs/language/STDLIB_TIERS.md:10` through `docs/language/STDLIB_TIERS.md:15` and `docs/language/STDLIB_TIERS.md:52` through `docs/language/STDLIB_TIERS.md:68`.
- PASS: Compiler package version and compiler release docs are aligned to `1.0.0-beta.23`. See `compiler/Cargo.toml:3`, `compiler/Cargo.lock:7`, `docs/compiler/RELEASE_NOTES.md:15` through `docs/compiler/RELEASE_NOTES.md:43`, and `docs/compiler/ROADMAP.md:126` through `docs/compiler/ROADMAP.md:132`.

## Verification

Ran:

```bash
node --check scripts/render-stdlib-api-doc.js
node --check scripts/check-stdlib-api-tiers.js
./scripts/check-stdlib-api-tiers.js
git diff --check
rg -n '^- `experimental`' docs/language/STDLIB_API.md
```

Result: all focused checks passed. The `rg` inspection confirmed 58 experimental helper signatures across the expected filesystem-handle, JSON, loopback networking, random, and time surfaces.

Recommended before release tag:

```bash
./scripts/render-stdlib-api-doc.sh
./scripts/release-gate.sh
```

Note: run the full release gate after the generated catalog changes are staged or committed; the gate intentionally fails if `docs/language/STDLIB_API.md` has unstaged generated-doc drift.
