docs(evidence): record live-deployment verification of finding 18dd05c10709 - #26
Conversation
…c10709 The meta-description fix for the home page (and the other four public pages) was merged as PR #21, with a source-string CI guard in check-site.mjs, but the live deployment was never measured. This closes that gap by recording a real-Chromium measurement of the five deployed tinystudio.io pages (2026-08-09): each serves exactly one non-empty, unique meta description in its head within search-snippet length, with no duplicates and no console errors. Dogfood finding 18dd05c10709 (missing meta description on home) is verified resolved on the deployed site.

- Line 38: Update the CSP evidence entries in the metadata table to record the
actual Content-Security-Policy header value captured from the served response,
rather than only “yes”; if the receipt contains only a presence check,
explicitly state that it did not record the policy value.
- Line 3: Update the measurement dates on both the metadata date entry and the
corresponding receipt entry to the actual execution date; do not use August 9,
2026 while the measurement is still in the future. If it has not run, defer the
closeout instead of marking the evidence complete.
- Around line 83-91: Update the source guard in check-site.mjs, particularly its
pageHtml description-tag scanning around the identified validation block, to
restrict accepted meta description matches to the document head and reject tags
outside it. Keep the existing validation rules intact; alternatively, explicitly
document this limitation in the referenced evidence text if the guard cannot be
scoped.
- Line 37: Align the evidence document’s reproduction steps and results with the
actual verification method: either add a complete runnable Playwright script
showing per-page iteration, page-error handlers, forbiddenClaims checks, and
corresponding assertions, or remove claims for checks not implemented and report
only console errors and other demonstrated results. Update the affected sections
consistently so every recorded result is supported by the shown method.

Do not mark a future measurement as completed evidence.
The receipt uses August 9, 2026 on Lines 3 and 40. This review is on August 8, 2026. A measurement dated August 9, 2026 cannot already support this closeout. Record the actual execution date, or defer the closeout until the measurement runs.

Make the reproduction steps match the recorded results.
The receipt claims that it captured page errors and checked forbidden promises. The results table reports only console errors. The code block does not show page-error handlers, a per-page loop, a forbiddenClaims check, or assertions for these results. Add a complete runnable Playwright script, or document only the checks that the shown method performs.

Record the CSP policy value if CSP is part of the evidence.
Line 38 says that the Content-Security-Policy header was captured, but the table records only yes. The PR objective says that the production CSP was recorded. Store the actual header value, or state that the receipt checked only header presence.

Align the source guard with the documented head-placement check.
The live criterion requires description tags in document.head on Lines 34-36. However, scripts/check-site.mjs:900-935 scans pageHtml and does not restrict matches to <head>. A description outside <head> can pass the source guard while failing the live criterion. Scope the guard to <head>, or state this limitation in Lines 85-91.

When a single valid tag moves below </head>, scripts/check-site.mjs:910 still accepts it because its regex scans the entire HTML file; moving the homepage tag into the body in a temporary copy still produced TinyStudio.io checks passed. In that scenario Chromium reports zero descriptions in document.head while CI remains green, so the claim here that the source guard prevents this regression is false. Either restrict the guard to the head or narrow the receipt's guarantee.
