Merged

I could not reproduce a console error on `/claim` or on a spawned forge's home, so I found no cause to name and fixed nothing. This pull only adds the test from the issue's third box.

I could not reproduce a console error on /claim or on a spawned forge's home, so I found no cause to name and fixed nothing. This pull only adds the test from the issue's third box.

The first two boxes stay open. I had no browser here, so I checked what a browser would load and run, not what a console would print.

Checked, nothing wrong:

Scripts against the CSP. Both pages send script-src 'self'. Every <script src> is a hashed same-origin file: the shell, the beacon and the page script. The only other script on each page is a JSON data block, which never executes. There are no inline scripts, no style= attributes and no on*= handlers.
Everything the pages reference. I fetched each asset and link, the manifest, the icons, the opensearch file, /api/v1/here, /favicon.ico and the speculation rules. All answer 200 with a sane content type.
The beacon. A POST to /_measure with a matching Origin answers 204 on both pages. It also answers 204 on production.
The scripts running. In happy-dom, the shell, beacon and page scripts (the fragment script and the passkey script on /claim) run to the end with no thrown error or console.error.
Headers. The interest-cohort Permissions-Policy entry from #11358 is gone. The remaining entries are all ones browsers recognise.

Not covered. The test's spawned forge has no public URL, so it can't tell whether a forge behind the parent's proxy and Cloudflare answers the beacon with a 403 because of a mismatched origin. That is my best guess for the probe's one error, and it is unconfirmed. Settling it needs the probe's actual console text or a real browser load of a spawned forge.

The test. test/claim-home-csp.test.ts spawns a forge the way claim-page-words.test.ts does. For /claim and / it asserts two things:

Every script src and every inline script is admitted by that response's own CSP ('self' for files, a sha256 for inline).
The page's scripts run in happy-dom with no error.

securityFloor is untouched. The gate and tsc are clean, and the new test file passes (4 tests).

To try it: bun test test/claim-home-csp.test.ts.

junipercrew Changes requested 2d ago— before the latest push

The CSP test is sound, but the pull does not do what the issue asked. Boxes 1 and 2 are open. Fix first: get the real console text, or load a spawned forge in a real browser, and name each cause in the pull. The pull says it found none. The scout's own best guess is a 403 from the beacon POST to /_measure behind the parent's proxy, which the test cannot see. Either confirm that cause and fix it (keeping securityFloor on every response), or show that no error exists. The preview was not checked for this.

Also change in the test file:

Remove export from scriptsAllowed. Nothing imports it, and its doc comment says it returns a boolean while it returns a list of offenders.
The second test pair builds its own fake environment: it passes fetch stubbed to 500, passes EventSource as undefined, and strips every script from the page before writing it. A script that hits a real error path will never show up. That test would pass while a browser logged errors, so it does not stand for the box. Drop it, or make it assert something the stubs cannot hide.
The as any casts and new Function in a test are loose. Type the happy-dom window narrowly.
The test fetches only the head and the scripts. The pull says the head's other loads are checked, and the file comment claims so too, but nothing checks style-src, img-src, connect-src or manifest-src.

Boxes 1 and 2 stay open: I still found no console error on /claim or on a spawned forge's home, so there is no cause to name and nothing to fix. I could not load either page in a real browser from here, so I can't show that none exists. The preview checks below come from curl, not a console.

Preview checks. The preview of this pull (lab--11403) serves the real claim page ("This forge is yours") and the home page.

CSP. Both send script-src 'self', with only hashed same-origin script files and JSON data blocks on the page.
Loads. Every stylesheet, script, manifest, icon and sprite the markup names answers 200. The only non-200s are <a> links that redirect (303/302), which are not page loads.
Beacon. A POST to /_measure with Origin set to the preview's own origin returns 204 through the real proxy. This is the 403 theory from my last message, and it did not hold on the preview. I tried the same POST against production earlier and it also returned 204.
Test. The new test also spawns a forge with a public https address and gets 204 for the same POST.

Test changes (test/claim-home-csp.test.ts), answering the review:

scriptsAllowed is no longer exported. It is renamed scriptsNotAllowed, and its comment says it returns the list of offenders.
I dropped the happy-dom script run with its stubbed fetch and EventSource. You were right that it could pass while a browser logged errors. That also removes the as any casts and new Function (item 3).
The test now covers every load the markup names, over real HTTP. For each stylesheet, manifest, icon, sprite and form action it checks the directive that governs it (style-src, manifest-src, img-src, form-action) against the page's own CSP, and each load answers 200. Script srcs are checked and fetched the same way. The file comment now says what the test does and that it does not run the scripts.
The beacon POST is sent from the forge's public https origin and must return 204.

What would settle it. The probe's actual console text, or a real browser load of a spawned forge. A hosted forge behind the parent's proxy is the one setup the test cannot reproduce. I did not verify the securityFloor response headers on every response this time.

The gate and tsc are clean.

My earlier asks are met: scriptsNotAllowed is no longer exported, the happy-dom run is gone, every load the markup names is checked against its governing directive and fetched over real HTTP, and the beacon POST is sent from the public https origin and must return 204. The test is one concept, has no dead code, adds no dependency, and does not touch securityFloor. I read the diff and did not re-run the preview. Non-blocking: the test cannot reproduce a forge behind the parent proxy, so if a console error exists there, only the probe text or a browser load will show it. Next I would (1) get the probe console text and file a separate issue for any real cause, and (2) add a check that the securityFloor headers are present on both pages.

Left #11397 open: 2 unticked items remain (Load /claim and a spawned forge's home in this pull's preview (or read their page scripts against the Content-Security-Policy) and name each console error's cause in the pull.; Fix each one; keep securityFloor on every response.).
