From 2dadddb0a05bfd0e9c26c4b73ab05ab30fe4df5a Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Sat, 30 May 2026 18:48:42 +0100 Subject: [PATCH 1/2] fix(scripts): make check-ts-allowlist.affine compile cleanly (compile-broken seed from #283) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The seed `.affine` port shipped in #283 never compiled — it used JS-style catch (`catch e { ... }`), bare-brace record literals (`{ raw: ..., ... }`), the private `collections::any` / `string::substring`, and a `string::substring` end-relative semantics call (start, end) where AS expects (start, length). None of these were caught at PR time because nothing in CI runs the AS compiler against the file (`governance-reusable.yml` still invokes the .ts). Refactor to compile cleanly: - `catch e { x }` → `catch { _ => x }` (x3) — AS catch is pattern-match arms. - `{ raw, rx }` → `#{ raw, rx }` (x2) — AS record literals need `#{}`. - Drop `use collections::{ any }` (private); inline the membership loop. - Drop `use string::{ trim, int_to_string, substring }` — `trim` and `int_to_string` are interpreter builtins; `substring` is private. Rewrite call sites to use the `string_sub(s, start, length)` builtin directly, adjusting the two end-relative calls (`len(g2)` -> `len(g2) - 1`). - License: MPL-2.0 -> PMPL-1.0-or-later, matching the .ts source and the per-repo policy in `.machine_readable/licensing-policy.toml`. Verification (from affinescript build oracle): - affinescript check -> Type checking passed - affinescript compile --deno-esm -> out.wasm (Deno-ESM) Workflow remains unchanged — `governance-reusable.yml` still invokes the `.ts` source of truth. This PR only unblocks the planned follow-up of swapping the workflow to the AS-compiled `.deno.js` entry point. Refs #239 (umbrella TS->AffineScript), #241 (STEP 2 tail-batch-1). Follow-up to #283 (seed PR).

Drop the `let _ =` wrappers; bare expression statements (`consoleError("...");`) lower cleanly and match the merged seed's pattern. 2. `ReferenceError: endsWith is not defined` `Deno.endsWith` is declared as `pub extern fn` in `Deno.affine` but has no entry in the Deno-ESM codegen lookup table — the compiler emits the call site but never the definition (other stdlib `extern fn`s like `walkRecursive`, `regexMatch`, `readTextFile` are codegen-known and get inline `__as_*` shims; `endsWith` isn't on that list). Restore the merged seed's defensive inline helper backed by the `string_sub` builtin and switch all call sites from `endsWith` → `ends_with`. End-to-end runtime verification on local fixtures: empty dir -> exit 0, success line src/Foo.ts violation -> exit 1, error block + file list mod.ts (filename ok) -> exit 0 scripts/x.ts (dir ok) -> exit 0 Behaviour matches the .ts source the regression suite asserts against.
