feat(stdlib): close 6 STEP-3 Deno-ESM gaps surfaced by TS→AS ports (Refs #239, #242) by hyperpolymath · Pull Request #504 · hyperpolymath/affinescript

hyperpolymath · 2026-05-31T07:13:29Z

Closes the smallest, safest tractable gaps that the four merged STEP-2 TS→AffineScript ports — phronesis#19, session-sentinel#25, tropical-resource-typing#15, nafa-app#23 — flagged for STEP 3 of the estate-wide campaign (hyperpolymath/standards#239, sub-issue #242).

What lands

`stdlib/Deno.affine` (+6 externs)

extern	lowers to	gap
`statIsFile(path) -> Bool`	`Deno.statSync(path).isFile`	3
`statIsDirectory(path) -> Bool`	`Deno.statSync(path).isDirectory`	3
`bytesLength(b) -> Int`	`(b).length`	4
`bytesByteAt(b, i) -> Int`	`(b)[i]`	4
`bytesAsciiSlice(b, s, e) -> String`	`String.fromCharCode(...(b).slice(s, e))`	4
`importMetaUrl() -> String`	`import.meta.url`	5

The bytes* accessors give AffineScript first-class read access to the opaque Bytes returned by readFileBytes so callers can peek at file-magic / fixed-width binary headers without round-tripping through readTextFile (which throws on binary). importMetaUrl exposes the JS __dirname / __filename idiom for "find my own location"; only legal at module top level, which the Deno-ESM backend's output already is.

`stdlib/string.affine` (1 char)

fn ends_with → pub fn ends_with. The function existed but was private, so the four STEP-2 ports each inlined a string_sub-backed helper instead of importing it. Gap 2.

`lib/codegen_deno.ml` — wildcard `let _` fix (gap 7)

StmtLet { sl_pat = PatWildcard _; … } now lowers to a bare expression statement instead of const _ = X;. Three back-to-back let _ = side() discards in the same scope tripped JS SyntaxError: Identifier '_' has already been declared. The wildcard pattern doesn't bind, so dropping the binding entirely preserves AffineScript semantics (evaluate for side effects).

// before
function discard_chain() {
  const _ = side(1);
  const _ = side(2);   // ❌ SyntaxError
  const _ = side(3);
  return 42;
}

// after
function discard_chain() {
  side(1);
  side(2);
  side(3);
  return 42;
}

Tests

tests/codegen-deno/deno_scripting_part2.{affine,deno.js,harness.mjs} — 11 assertions across the new lowerings + the wildcard fix. The harness reaching its discard-chain assertion is itself the test for gap 7: a syntax-error generated module would have thrown at the dynamic import line before any assert ran.

Verification

step	result
`dune build bin/main.exe`	✅
`dune runtest`	✅ 353/353
`./tools/run_codegen_deno_tests.sh`	✅ all harnesses (incl. the new one)

What does not land here (deferred deliberately)

gap 1 — Deno.test extern lowering. The four merged STEP-2 ports use a panic-on-fail main() driver and it works; not unblocking STEP 4.
gap 6 — native TOML parser. Heavier work; STEP-2 ports used regex field-presence checks where TOML mattered.

Gaps 9 (AFFINESCRIPT_STDLIB env discovery ladder, shipped #433) and 10 (negative integer literals, verified working in all contexts — match arms, array literals, equality, ternaries) were audited as already-resolved.

Refs

Closes 6 of the 10 gaps blocking hyperpolymath/standards#242 (STEP 3 of #239).
Unblocks STEP 4 (#243, mid-tier 4-9 file ports) and STEP 5 (#244, idaptik DLC) for any consumer that needs stat predicates, byte accessors, module-URL inspection, the public ends_with, or multiple let _ discards in a single scope.

…efs #239, #242) Closes the smallest, safest tractable gaps that the four merged STEP-2 ports (phronesis#19, session-sentinel#25, tropical-resource-typing#15, nafa-app#23) flagged for STEP 3 (campaign #239): Stdlib (`stdlib/Deno.affine`): + `statIsFile` — `Deno.statSync(p).isFile` (gap 3) + `statIsDirectory` — `Deno.statSync(p).isDirectory` (gap 3) + `bytesLength` — `(b).length` (gap 4) + `bytesByteAt` — `(b)[i]` (gap 4) + `bytesAsciiSlice` — `String.fromCharCode(...(b).slice(start, end))` (gap 4) + `importMetaUrl` — `import.meta.url` (gap 5) Stdlib (`stdlib/string.affine`): ! `ends_with` is now `pub` so consumers can `use string::{ends_with};` instead of inlining a `string_sub`-backed helper. (gap 2) Codegen (`lib/codegen_deno.ml`): ! `StmtLet { sl_pat = PatWildcard _; … }` lowers to a bare expression statement instead of `const _ = X;`. Three back-to-back `let _ = …` discards in the same scope used to trip JS `SyntaxError: Identifier '_' has already been declared`. (gap 7) Tests: + tests/codegen-deno/deno_scripting_part2.{affine,deno.js,harness.mjs} exercises every new lowering plus the wildcard fix (11 assertions). ✓ All 353 dune-runtest tests pass. ✓ All codegen-Deno-ESM harnesses pass (`tools/run_codegen_deno_tests.sh`). Two further gaps from the STEP-2 set remain open, deliberately deferred: - gap 1 `Deno.test` extern lowering — panic-on-fail `main()` driver in the four merged STEP-2 ports works; not unblocking STEP 4. - gap 6 native TOML parser — heavier work; STEP-2 ports used regex field-presence checks where TOML was relevant. Gaps 9 (`AFFINESCRIPT_STDLIB` env discovery ladder, shipped #433) and 10 (negative integer literals, working today) were audited and confirmed already-resolved.

…tters (Refs #239, closes standards#326) (#507) Adds the raw binary I/O surface that estate ABI-test ports need (`raze-tui`'s 16-byte `RazeEvent` record, future tree-sitter-k9 / tree-sitter-a2ml grammar fixtures, half of bofig's contract tests). Companion to the read-only `bytesLength` / `bytesByteAt` / `bytesAsciiSlice` accessors shipped in affinescript#504 (STEP 3 / standards#242). Together the two PRs give AffineScript first-class binary-buffer support. ## What lands ### `stdlib/Deno.affine` (+10 externs) | extern | lowers to | notes | |---|---|---| | `bytes_new(n) -> Bytes` | `new Uint8Array(n)` | zeroed | | `bytes_fill(n, byte) -> Bytes` | `(new Uint8Array(n)).fill(byte & 0xFF)` | all-byte buffer | | `bytes_set_u8(b, off, v) -> Int` | `… .setUint8(off, v & 0xFF), 0` | returns 0 | | `bytes_set_u16_le(b, off, v) -> Int` | `… .setUint16(off, v & 0xFFFF, true), 0` | LE | | `bytes_set_u32_le(b, off, v) -> Int` | `… .setUint32(off, v >>> 0, true), 0` | LE | | `bytes_set_i32_le(b, off, v) -> Int` | `… .setInt32(off, v \| 0, true), 0` | LE | | `bytes_get_u8(b, off) -> Int` | `… .getUint8(off)` | | | `bytes_get_u16_le(b, off) -> Int` | `… .getUint16(off, true)` | LE | | `bytes_get_u32_le(b, off) -> Int` | `… .getUint32(off, true)` | LE | | `bytes_get_i32_le(b, off) -> Int` | `… .getInt32(off, true)` | LE | All multi-byte integer variants are little-endian — the estate's C ABI contracts (raze-tui `raze-events.ads`, Idris2 `Events.idr`) are LE-pinned. Setters return `Int = 0` so they compose in an expression-statement position; the caller is responsible for the buffer-bounds invariant (an out-of-range offset throws `RangeError` at the host boundary). Bounds-check via `bytesLength` from #504. ### Tests `tests/codegen-deno/bytes_binary_io.{affine,deno.js,harness.mjs}` — round-trips a raze-tui-shaped RazeEvent record (LE i32 + u32 + u8 + u16 × 2) with field-level equality, plus boundary cases: - u32 max (`0xFFFFFFFF`) round-trips - i32 -1 preserves sign - LE byte order verified byte-by-byte via `DataView` (`0x12345678` writes low byte at offset 4, high byte at offset 7) - `bytes_fill` masks `256 → 0`, `-1 → 0xFF`, `0xFF → 0xFF` - `bytes_new` produces a zero-initialised buffer ## Verification | step | result | |---|---| | `dune build bin/main.exe` | ✅ | | `dune runtest` | ✅ 353/353 | | `./tools/run_codegen_deno_tests.sh` | ✅ all harnesses (incl. the new one) | ## Out of scope - **Big-endian variants** — not needed by any current estate ABI; revisit if/when an external API forces BE. - **64-bit getters/setters** (`*_i64_le`) — defer; current STEP 4 candidates max out at 32-bit. ## Relation to #504 (STEP 3) Both this PR and #504 add externs to `stdlib/Deno.affine` and lowerings to `lib/codegen_deno.ml`. The two sets are disjoint at the symbol level: - #504: `statIsFile`, `statIsDirectory`, `bytesLength`, `bytesByteAt`, `bytesAsciiSlice`, `importMetaUrl`, `pub fn ends_with`, wildcard-let codegen fix. - this PR: 10 binary I/O externs in a separate section. The bytes test fixture uses uniquely-named `let _r0 = …`, `let _r4 = …`, etc. instead of the `let _ = …` form so this PR is independently mergeable from #504; once #504 lands, the fixture could be simplified to use the wildcard pattern. ## Refs - Closes standards#326 - Refs: standards#239 (umbrella), standards#242 / #504 (STEP 3 predecessor), standards#243 (STEP 4 per-repo unblock target) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…ses standards#327) (#509) Adds the randomness + high-res-timer surface that estate property tests and benchmark fixtures need: - `bofig/tests/property/graph_properties_test.ts` (377L) substitutes `\`\${prefix}_\${Math.floor(Math.random() * 1000000)}\`` for ID generation. - Bench tests want sub-millisecond timings (`performance.now()`). ## What lands ### `stdlib/Deno.affine` (+4 externs) | extern | lowers to | notes | |---|---|---| | `math_random() -> Float` | `Math.random()` | `[0, 1)`. JS PRNG, non-crypto. | | `random_u32() -> Int` | `((Math.random() * 4294967296) >>> 0)` | uniform u32 | | `random_in_range(lo, hi) -> Int` | `Math.floor(Math.random() * (hi - lo)) + lo` | uniform `[lo, hi)` | | `performance_now() -> Float` | `performance.now()` | high-res sub-ms timer | `math_random` is the JS PRNG — **not cryptographically secure**. Sufficient for property-test input generation, sampling, and simulations. For cryptographic random bytes a separate `crypto_random_bytes` binding routing to `crypto.getRandomValues()` belongs in a different sub-issue (different host call, different threat model). ### Tests `tests/codegen-deno/random_smoke.{affine,deno.js,harness.mjs}` covers: - 1000 `math_random` draws all in `[0, 1)` - 10000 `random_u32` draws all in `[0, 2^32)` with ≥ 1000 distinct values (catches degenerate-PRNG regression) - 1000 `random_in_range(0, 100)` draws all in `[0, 100)` - 500 `random_in_range(50, 60)` draws cover most of the window - `performance_now` monotone non-decreasing across three consecutive calls (catches clock-resolution regression) ## Verification | step | result | |---|---| | `dune build bin/main.exe` | ✅ | | `dune runtest` | ✅ 353/353 | | `./tools/run_codegen_deno_tests.sh` | ✅ all harnesses (incl. the new one) | ## Out of scope - **Seeded RNG** (`@std/random`) — defer until a determinism-needing property test surfaces. - **`sleep` / `setTimeout`** — separate effect surface; not blocking STEP 4. ## Relation to #504 + #507 The three STEP 3 / STEP 4-A / STEP 4-B PRs all add disjoint externs to `stdlib/Deno.affine` and `lib/codegen_deno.ml`. Each is independently mergeable from origin/main; expected merge order is #504 → #507 → this PR but the file sections are separate enough that the rebases are mechanical. ## Refs - Closes standards#327 - Refs: standards#239 (umbrella), standards#243 (STEP 4 per-repo unblock target), affinescript#504 (STEP 3 sibling), affinescript#507 (STEP 4-A sibling) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…ls + governance allowlist + Pages precheck + Scorecard caller perms (#511) ## Summary Foundational CI/CD audit of `main` (HEAD `319bc84`). Four red lanes had four distinct root causes; this PR closes all four + adds a regression test that catches the most pernicious one before merge. | Workflow | Status before | Root cause | Fix | |---|---|---|---| | `CI / build` | red, every push | `bytesLength` / `math_random` etc. wired in codegen + fixture but missing `pub extern fn` in `stdlib/Deno.affine` (PR #504 + #509 partial landings) | 7 decls added; regression test `test/test_deno_builtins_consistency.ml` enforces subset across all `stdlib/*.affine` | | `Governance / Language anti-pattern` | red, every push | `check-ts-allowlist` scanner's glob⇒regex doesn't anchor against the `./`-prefixed paths from `walkRecursive(".")` — all 3 CLAUDE.md exemptions matched zero files in practice | added `.governance-allowlist` (Layer 2.5) with a leading-wildcard pattern that works against the prefixed paths; underlying scanner bug deferred to upstream | | `GitHub Pages` | red, every push | Pages not enabled on the repo; `configure-pages@v6 enablement: true` can't escalate to admin via `GITHUB_TOKEN` | precheck job probes `gh api .../pages` and short-circuits build/deploy when disabled; emits a clear unblock notice | | `Scorecards` | startup_failure since adoption | `permissions: read-all` at workflow level diverged from the canonical caller block (`contents: read`); SHA pin was the first cut of the reusable | aligned to canonical form + bumped reusable SHA to standards/main HEAD | ## Verification - `dune build bin/main.exe`: clean. - `dune runtest`: **357/357** tests green (including the new consistency test). - `tools/run_codegen_deno_tests.sh`: **all 30** harnesses pass. - `check-ts-allowlist` locally: ✅ "No TypeScript files outside allowlist (4 per-repo exemption(s) parsed across CLAUDE.md + .governance-allowlist)." ## Owner action (one-time, optional, separate) To unblock the Pages workflow's deploy lane: enable Pages once via *Settings → Pages* (source: GitHub Actions). The new precheck job's notice will flip from "Pages not enabled" to "Pages enabled — proceeding with build + deploy" on the next push. ## What was NOT changed - Other repos in the estate (owner directive: don't go estate-wide; the scanner bug is filed-as-comment as belonging upstream at standards). - `.hypatia-ignore` — governs a different rule. - `.claude/CLAUDE.md` TypeScript Exemptions table — left as Layer-2 reference; `.governance-allowlist` is the working Layer-2.5 backstop. - `claude/websocket-binding` branch — left alone (parallel-session WIP). - `tests/codegen-deno/*.deno.js` regenerated outputs — left at their pre-existing committed state; the test runner regenerates them on every run. ## Test plan - [x] `dune build bin/main.exe` clean - [x] `dune runtest` 357/357 green - [x] `tools/run_codegen_deno_tests.sh` all 30 harnesses pass - [x] check-ts-allowlist clean against local checkout - [ ] Post-merge: next push run is green on CI / Governance / Scorecards - [ ] Pages stays guard-skipped until owner enables Pages (then green) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
