Summary

Follow-ups from the claude-review on #877 (stacked on it; GitHub retargets this PR to main when #877 merges).

1. Render tests for SqlOutput and TranspileTab error, success and empty states (website/scripts/sqlOutput.test.mjs): real components transpiled in-process with typescript and rendered with react-dom/server; only the CodeMirror editor is stubbed. No new dependencies.
2. Copy feedback timers: one useCopyFeedback hook (backed by a pure, unit-tested createCopyFeedback) for the Format/Transpile output, Lint, AST and "go get" copy buttons. A second click restarts the reset timer, unmount clears it, and the "go get" copy now shows a failure instead of an unhandled rejection.
3. Dialect arguments documented: parse/format/lint/analyze/highlight use generic rules for an unknown dialect; transpile returns unsupported source|target dialect "x" (JSDoc in WasmLoader.tsx, wasm/main.go, new table in docs/HIGHLIGHTING.md). Behaviour unchanged; a Go test pins the format fallback.
4. error_span dropped from the Format/Transpile payload: nothing read it, and the editor already marks the same parse error from Lint/Analyze parse_error_span. Contract fixture, types and tests updated.
5. WASM delivery: confirmed lazy-loaded (next/dynamic, runtime fetch) and served brotli-compressed by Vercel; only change is clamping download progress to 1.

Test Plan

• cd website && npm run typecheck && npm run lint && npm test — 44/44 pass; lint warnings unchanged from base (7, pre-existing)
• go test ./wasm/..., GOOS=js GOARCH=wasm go vet ./wasm/
• pre-commit hook (fmt, vet, short tests)

Breaking Changes

The WASM format / transpile JSON no longer includes error_span on failure. It was undocumented outside the bridge types and unused by the site.

Review of PR #888

I read the diff only. I didn't run the tests.

The change is clean overall. The createCopyFeedback / useCopyFeedback split makes the timer logic testable without a DOM. The error_span removal is applied consistently across the Go struct, the Go tests, the JSON fixture, the TS types and the contract check. ErrorSpan is still imported in bridgeContract.check.ts because the lint and analyze checks use it, so there's no unused import.

Issues

1. The "go get" copy button still doesn't show a failure (Playground.tsx:142-149, :349).

   • The PR description says the copy "now shows a failure instead of an unhandled rejection".
   • The code only fixes the unhandled rejection. It destructures just { copied, flash } and calls flash("failed").
   • The button label is copied ? '✓ Copied' : 'Copy', so a failed copy shows nothing.
   • Fix: also destructure copyFailed and render a failed label, as FormatTab, LintTab and AstTab do. Otherwise correct the description.

2. Small robustness points (non-blocking)

   • In useCopyFeedback, flash is a no-op until the effect has run. That's fine for click handlers.
   • Under React StrictMode the effect disposes and recreates the feedback object. That works, but a disposed object isn't reused, which is correct.
   • The Math.min(1, received / total) clamp is good. Since total > 0 is checked before the read loop, there is no division by zero.

3. Style nit: the useCopyFeedback import sits above the react import in AstTab, FormatTab, LintTab and Playground. Put it after the react import to match the usual ordering.

4. Test coverage

   • The render tests for SqlOutput and TranspileTab cover the error, success and empty states well. Stubbing only SqlEditor keeps them realistic.
   • The loader hook relies on node:module registerHooks. That needs a recent Node, so check that CI's Node version supports it.
   • There is no test that the hook wiring clears the timer on unmount, but createCopyFeedback covers that logic directly.

5. Breaking change: dropping error_span is documented in the description. It would be worth a line in CHANGELOG.md under [Unreleased], per CLAUDE.md.

The only item I'd fix before merging is #1.

Review of PR #888

I read the diff and the key files (useCopyFeedback.ts, Playground.tsx). I didn't run the tests.

Summary

The change is solid. Splitting the timer logic into the pure createCopyFeedback makes it unit-testable without a DOM. The error_span removal is consistent across the Go struct, Go tests, JSON fixture, TS types and the contract check. Clamping download progress to 1 is correct.

Issues

1. The "go get" copy button doesn't show a failure (website/src/components/playground/Playground.tsx:142-150, :349) — worth fixing before merge.

   • The PR description says the copy "now shows a failure".
   • The code destructures only { copied, flash } and calls flash("failed"), but the label is copied ? '✓ Copied' : 'Copy'. A failed copy shows nothing.
   • The unhandled rejection is fixed, but the failure state is never rendered.
   • Fix: destructure copyFailed and render a failed label, as FormatTab, LintTab and AstTab do. Otherwise correct the description.

2. Non-blocking: flash is a no-op until the effect has run.

   • feedback.current is null before mount, so a call made before then is silently dropped.
   • This is fine for click handlers, which only fire after mount.
   • Under StrictMode the effect disposes and recreates the feedback object. That works.

3. Style nit: the useCopyFeedback import sits above the react import in AstTab, FormatTab, LintTab and Playground. Put it after the react import to match the usual ordering.

4. Tests

   • The SqlOutput and TranspileTab render tests cover the error, success and empty states well, and stubbing only the editor keeps them realistic.
   • The loader hook uses node:module registerHooks. Confirm CI's Node version supports it.
   • No test checks that the hook clears the timer on unmount. createCopyFeedback covers that logic directly, so this is minor.

5. Breaking change: dropping error_span is documented in the PR body. Add a line under [Unreleased] in CHANGELOG.md, per CLAUDE.md.

Security and performance

I found no security concerns. The WASM bundle stays lazy-loaded.

Review of PR #888

I read the diff and re-checked the current branch. I didn't run the tests.

Summary

The change is solid. createCopyFeedback is pure and unit-testable, and useCopyFeedback wraps it cleanly. The error_span removal is consistent across the Go struct, Go tests, fixture, TS types and contract check. Clamping download progress to 1 is correct.

Issues

1. The "go get" copy button still doesn't show a failure (website/src/components/playground/Playground.tsx:142-150, :349). I'd fix this before merge.

   • Fix: destructure copyFailed and render a failed label, as FormatTab, LintTab and AstTab do. Otherwise reword the description.

2. Changelog: CHANGELOG.md has an [Unreleased] section (line 8), but I found no entry for the error_span removal. It is a breaking change to the WASM JSON, so add a line there, per CLAUDE.md.

3. Non-blocking: flash is a no-op before the effect runs. feedback.current is null until mount. Click handlers only fire after mount, so this is fine. The StrictMode dispose and recreate cycle also works.

4. Style nit: the useCopyFeedback import sits above the react import in some files. Put it after for consistency.
