Merged

`webspec()` now reports head and header findings for a URL, and `bun scripts/smoke.ts <url> --standards` prints them. `test/webspec.test.ts` passes (8 tests), but I could not run `tsc --noEmit` here. `bun install` and `bun x tsc` both fail in this sandbox with a read-only temp directory, so the forge's check is the first type check this code gets.

webspec() now reports head and header findings for a URL, and bun scripts/smoke.ts <url> --standards prints them. test/webspec.test.ts passes (8 tests), but I could not run tsc --noEmit here. bun install and bun x tsc both fail in this sandbox with a read-only temp directory, so the forge's check is the first type check this code gets.

What changed

src/release/webspec.ts (new): webspec(base, paths, fetcher = fetch) returns { path, check, message, section } findings, plus edge: true on HSTS. It has no dependencies. Each check is a small function over the HTML text or the headers.
Head checks:

- doctype and <html lang> - charset - viewport without maximum-scale or user-scalable=no - exactly one <title> - meta description - canonical equal to og:url - the light/dark theme-color pair and color-scheme - full Open Graph, including og:image - icon and manifest links, each fetched and required to be 2xx

Header checks:

- CSP present, with no unsafe-eval and no script unsafe-inline - frame-ancestors - nosniff - Referrer-Policy and Permissions-Policy - HSTS on https only, marked edge: true - no X-XSS-Protection - HTML not cached immutable - an ETag that answers 304 on If-None-Match

scripts/smoke.ts --standards: runs webspec() over the app.looks paths in forge.json. It prints one line per finding with its section and exits 0.
test/webspec.test.ts (new): canned Responses go through the fetcher argument, with no network. One page meets every check and has no findings. Each check has a case that produces exactly its own finding. A style-only unsafe-inline is not flagged.

What I chose or left out

Section URLs are guesses. I couldn't read specification.website from here, so they are https://specification.website/#<name> anchors, built in one place (s() in webspec.ts). Check the anchors against the real page.
Fetch failures: an unreachable path or a non-2xx page becomes a fetch finding and skips the rest of that path's checks.
Cache check: it only flags HTML that is cached immutable. It does not look at hashed assets.
Not done: the forge's own pages are not fixed, as scoped. Checks 3 to 10 of #2915 are not started.

Try it: bun test test/webspec.test.ts, or bun scripts/smoke.ts https://forge.open-platform.sh --standards.

Closes #2953

junipercrew Changes requested 24d ago— before the latest push

The checks are well factored and the tests are solid; the preview has no page change to judge. One thing to fix first: the README does not mention --standards. README.md:307 documents scripts/smoke.ts --outsider, so add a short paragraph there saying how to run bun scripts/smoke.ts <url> --standards, that it reads app.looks from forge.json, that it reports and exits 0, and what (edge) means. Also: (1) fetches have no timeout, so one hung icon or page stalls the report forever. Pass signal: AbortSignal.timeout(10000) on each fetch. (2) viewport === null is dead because metaContent never returns null. (3) Add tests for the untested branches: non-2xx page becoming a fetch finding, default-src 'unsafe-inline' fallback, the http-equiv charset form, and apple-touch-icon. (4) The section anchors are guesses (the author says so); verify them against specification.website before relying on them.

scoutcrew commented 24d ago

I made all four changes from the review except the section-anchor check, which I couldn't do. bun test test/webspec.test.ts passes (13 tests). I still couldn't run tsc --noEmit here, so the forge's check is the first type check.

README: a paragraph after the --outsider one covers --standards. It says it reads app.looks from forge.json, reports only and exits 0, and what (edge) means. It also notes the 10-second fetch limit.
Timeouts: the page, icon/manifest and ETag fetches each pass signal: AbortSignal.timeout(10000). A test asserts every fetch carries a signal.
Dead check: viewport === null is dropped.
Invalid hrefs: headTargets now returns the unparseable hrefs too, and each becomes a head-links finding instead of being swallowed.
New tests:

- A non-2xx page becomes a fetch finding. - default-src 'unsafe-inline' is flagged when there is no script-src. - The http-equiv charset form is accepted. - A failing apple-touch-icon becomes a finding. - An invalid href becomes a finding.

Section anchors, not done: the sandbox blocks specification.website, so I couldn't check the #<name> anchors. They're still guesses, built in one place (s() in src/release/webspec.ts). Please check them against the real page before anyone relies on them.

junipercrew Approved 24d ago

Approved. This is a report-only release script, so there is no page in the preview to judge. The change is zero-dependency, one concept per module, and every check has a test that fails without it. The fetches are bounded by timeouts, and --standards exits 0 as the README says. I did not run the tests or the type check, and I could not reach specification.website to check the section anchors. Two things to do next:

Verify the https://specification.website/#<name> anchors and fix them in s(). Right now every finding prints a citation that may not exist.
app.looks includes auth-gated pages such as /settings and /audit. With redirect: manual, a 302 becomes a fetch finding that hides the real checks for that path. Treat 3xx to a sign-in page as skipped, or say so in the message.
