docs+ci: testing/bench/coverage/panic-attack hygiene uplift (DOC-10..12)
Adds the four standards documents and CI scaffolding the testing survey flagged as missing: - docs/standards/TESTING.adoc (DOC-10) — authoritative test taxonomy (alcotest unit / alcotest E2E / fixture / golden / smoke / microbench), PR-level expectations, deferred-regression-test protocol. Pointers go through CAPABILITY-MATRIX for the live gate count rather than hard-coding it. - docs/standards/PANIC-ATTACK.adoc (DOC-11) — SOP for the estate compliance scanner. Disposition vocabulary (fix/accept/suppress/ defer); standing-suppression record format. Companion workflow .github/workflows/panic-attack.yml runs weekly on Sunday 03:00 UTC + workflow_dispatch; uploads the log as artifact. Per-PR invocation is intentionally out of scope (codeql/semgrep/secret- scanner already cover per-PR at finer granularity). - bench/ scaffold (DOC-12, half) — dune stanza under @bench alias, 4 phase microbenches (lex / parse / typecheck+quantity / codegen-wasm) over 3 shared fixtures. just bench / just bench-record recipes. CI job bench-visibility uploads bench-output.log as artifact + step summary. Visibility-only — no merge-blocking threshold. - bisect_ppx coverage (DOC-12, half) — added as with-test depend in dune-project + affinescript.opam. just coverage recipe (HTML to _coverage/, gitignored). CI job coverage-visibility uploads _coverage as artifact + summary. Visibility-only — no enforced floor (ratchet prerequisite: calibrated baseline). - Stale TESTING-REPORT.adoc + .scm retired in-place with redirects to CAPABILITY-MATRIX.adoc + standards/TESTING.adoc. The 2025-12-29 "47 PASS / 27 FAIL / 63.5%" snapshot has been contradicted by the live gate (>250 / 0 fail) for the entire first half of 2026; a DOC-09 over-claim hazard if left in place. - STATE.a2ml drift-flag refreshed: live gate is 260/260 at 2026-05-19 reconstruction, lifted by subsequent borrow-checker PRs (#240 → 263, return-escape → 271/274, &mut surface → 278/281); exact live number comes from dune runtest --force per commit, not this file. Session-note hygiene-uplift-2026-05-23 recorded. - TECH-DEBT.adoc DOC-10/11/12 entries added. - NAVIGATION.adoc + docs/README.adoc updated to list the new standards and mark TESTING-REPORT as RETIRED. Not yet verified locally (no OCaml toolchain in this remote execution environment); rely on CI for build + test + bench verification. Refs #175, #176

(2) PR #304 OPENED for #301 (repo-wide PMPL→MPL-2.0 SPDX surface sweep, Option 3 of the three in the issue): 673 files / +1127 −711 / 1116 SPDX headers flipped / code generators emit MPL-2.0 / .machine_readable license fields reconciled / dune-project (license …) reconciled from stale MIT-OR-AGPL → MPL-2.0 / affinescript.opam regenerated → license: \"MPL-2.0\" / LICENSES/LICENSE-MPL-2.0 added (canonical Mozilla 373-line text) / root LICENSE narrative preserved unchanged (PMPL still narrated as preferred + MPL-2.0 fallback explanation intact) / vendored sister-repo subtrees (road-skate/ + affinescript-vite/) explicitly excluded. Verification: 295/295 dune tests + 6/6 shim tests + binary 0.1.1 + grep for residual PMPL SPDX → empty (excl. vendored). Side-effect noted in PR body: pre-existing dune-project symlink-to-.build/dune-project got broken by sed atomic-rename; both files now real-file content-identical. (3) Issue #302 CLOSED — owner confirmed GitLab+Bitbucket mirroring is intentionally off; Codeberg + Radicle are the active forges. (4) repos-monorepo RETIREMENT decided: snapshot tarred (23MB gzip / 144MB extracted / 23,970 entries / canonical origin/main shallow-clone / .git excluded) to /mnt/c/Users/USER/Downloads/repos-monorepo-snapshot-2026-05-20.tar.gz; owner-upload-to-Google-Drive then `gh repo delete hyperpolymath/repos-monorepo --yes`. repos-monorepo#9 (nested casket-ssg coherence) becomes moot post-delete since the aggregator that would have carried it is gone — standalone hyperpolymath/casket-ssg already merged casket-ssg#8 + has its own instant-sync.yml for forge propagation.

PRs that landed today: #291 (partial pins.js fill for linux-x64 + macos-arm64, shim 0.1.1 — bridging before macos-x64 leg landed); #292 (release.yml: retired macos-13 GH-hosted runner → macos-15-intel — root cause of v0.1.0 macos-x64 leg sitting queued ~10h, traced to actions/runner-images#13046/#13402/#13634 'macos-13 fully unsupported since 2025-12-04'); v0.1.1 tag cut, full 3-platform release (linux-x64/macos-arm64/macos-x64) + SHA256SUMS published; #293 (delete 4 orphan .res files + the affine-res ReScript-bindings package — same precedent as packages/affine-ts/ removal 2026-05-11, fixed the recurring governance Language/anti-pattern check failure on every PR); #294 (release.yml checksums job: pass --repo \"$GITHUB_REPOSITORY\" so `gh release download` doesn't probe a missing .git — bug hidden on v0.1.0 by the macos-13 stall that pre-empted the checksums leg); #295 (final shim closure: pins.js VERSION→v0.1.1, all 3 sha256 fields filled, shim @hyperpolymath/affinescript 0.1.1→0.1.2, SHIM_SPEC bumped lock-step in tools/affinescript-lsp/src/compiler.rs); #298 (cross-runtime refactor: Deno/Bun/Node detection at module load + helper layer for hostOs/hostArch/envGet/readBytes/writeBytes/mkdirRecursive/chmodExec/spawnInherit/thisIsMain — was Deno-only — plus mod.d.ts + triple-slash reference so JSR fast-check finds the types and emits no warning; .claude/CLAUDE.md gained Runtime Exemptions section as the carve-out from the estate-wide Bun/Node ban); #299 (relicense the JSR shim package only — packages/affinescript-cli/{deno.json + 4 SPDX headers} — from MPL-2.0 to MPL-2.0 because JSR validates against the SPDX list and `MPL-2.0` isn't on it; wider repo PMPL→MPL-2.0 deliberately deferred — #301). (2) JSR FIRST-TIME PUBLISH RECIPE walked: claim scope @hyperpolymath → create package record (jsr.io/new — dry-run won't catch this) → link trusted GitHub repo at package or scope settings (OIDC actorNotAuthorized otherwise — dry-run won't catch this either) → SPDX licence → mod.d.ts + triple-slash → cross-runtime tickbox. publish-jsr.yml workflow (manual workflow_dispatch); 6 dispatched runs today before all gates aligned (~7:33 UTC). Verified live: https://jsr.io/@hyperpolymath/affinescript 200; meta.json `latest: 0.1.2`. Real fetch+verify+exec smoke against the v0.1.1 release ran green on linux-x64 (resolveCompiler → SHA-verify → cache → exec `--version`). (3) ESTATE macos-13 SWEEP — sole non-affinescript first-party hits: `casket-ssg#8` (release.yml: `runner: macos-13` → `runner: macos-15-intel`, merged) + `proven#29` (zig-ffi.yml: `os: macos-13` → `os: macos-15-intel`, merged) + `repos-monorepo#9` (nested casket-ssg copy in boj-cartridges/polystack/poly-ssg/casket-ssg/.github/workflows/release.yml — still open as of writing, coherence-only since instant-sync.yml in each repo independently propagates). gh search code confirmed only 3 distinct first-party repo hits across the 360-repo active estate. (4) DISCOVERED — GitLab + Bitbucket mirrors NOT operating: empirical inspection of mirror.yml runs on affinescript / casket-ssg / repos-monorepo all `completed/skipped`; `GITLAB_MIRROR_ENABLED` / `BITBUCKET_MIRROR_ENABLED` repo vars unset; `GITLAB_TOKEN` / `BITBUCKET_TOKEN` secrets absent (only FARM_DISPATCH_TOKEN present); gitlab.com probes 302, bitbucket.org probes 404. repos-monorepo DOES have CODEBERG_MIRROR_ENABLED + RADICLE_MIRROR_ENABLED set → active forges are Codeberg + Radicle + whatever `.git-private-farm` fans out to. Filed as open question: #302. (5) FOLLOW-UPS: #297 (version-string drift — bin/main.ml/lib/repl.ml/lib/lsp_server.ml/lib/onnx_codegen.ml/dune-project all hardcoded `0.1.0` even on the v0.1.1 binary; fix PR #300 introduces lib/version.ml single-source-of-truth + release.yml sed-bake step on every tag); #301 (wider PMPL→MPL-2.0 estate-relicense decision needed); #302 (mirror status — intentional-off or unfinished-setup). (6) DOCUMENTATION: this file (a session-note); docs/PACKAGING.adoc (status table for all 3 JSR-publishable packages + first-publish-gotchas section); docs/TECH-DEBT.adoc (INT-04 / INT-10 lines updated to reflect actual publish).

Resolve registers the symbol; Typecheck.check_fn_decl special-cases FnExtern to register the polymorphic scheme without body checking; Codegen.gen_decl emits a real `(import \"env\" \"<name>\" (func ...))` for each extern fn, mirroring gen_imports's cross-module shape. Borrow + Quantity skip extern fns. lib/dune now demotes warning 8/9 from error to warning so the new variants don't require lock-step updates across all 27 codegens (any non-Wasm codegen that doesn't handle FnExtern raises Match_failure with file:line at runtime — correct signal for 'this target has no story for host-supplied implementations'). 192 tests; 0 regressions. (2) Issue #35 Phase 2: stdlib/Vscode.affine and stdlib/VscodeLanguageClient.affine ship the ~12 + 3 binding declarations from the issue's API inventory (registerCommand, getConfiguration, showInformationMessage, createTerminal, ...). packages/affine-vscode/mod.js is the JS-side adapter that translates each `extern fn` invocation into the corresponding vscode/lc API call, with a JS-side handle table for opaque host objects and a string-marshal helper that reads `[u32 length][utf-8 bytes]` out of the wasm memory. Adapter returns a namespaced object `{ Vscode: {...}, VscodeLanguageClient: {...} }` matching the WASM cross-module imports' module names. examples/vscode_extension_minimal.affine demonstrates an end-to-end VS Code extension authored in AffineScript using `use Vscode::{registerCommand, showInformationMessage, pushSubscription}` — compiles to .cjs via the Node-CJS path. (3) issues-drafts/02 closed: `[T]` array type now parses via `LBRACKET type_expr RBRACKET → TyApp (Array, [TyArg elem])` in lib/parser.mly's type_expr_primary rule. Verified for fn params, return types, struct fields, and nested `[[T]]`. Other stdlib files (Option/math/io/string) still fail with distinct issues (`fn() -> T` type syntax, `Option<T>` angle brackets) — the array fix advanced math.affine's failure point from line 349 to 354 etc. (4) PatCon sub-pattern destructuring under WasmGC: `match Mk(7, 99) { Mk(a, b) => a }` now lowers to RefCast + StructGet for the tag check + per-field RefCast HtI31 + I31GetS unboxing for each PatVar sub-pattern. Validated end-to-end: emitted .wasm instantiates in Deno and `main()` returns 7. The mixed-arity case (zero-arg + with-args in same enum, e.g. Option) errors loudly with the workaround documented (split into two matches, or use Wasm 1.0). Unifying variant rep — uniform `struct {tag, payload}` so Some+None can share — is the next destructuring milestone. 195 → 198 → 200 tests; 0 regressions throughout."
