Your suggestion to use DevTools device mode was right; "cannot be checked" was
too quick a conclusion. On an emulated Pixel 9 (412x924, mobile UA, with a
reload so Facebook serves the mobile bundle) the Page's mobile header renders
412x274 = 1.504:1. Facebook keeps the cover's full height and shows only the
centre 938 px of its 1640 px width -- 351 px off each side. build.py's safe
area leaves 306 px clear per side, 45 px too few, and the light text in
cover-c.png runs x333..x997 against a left crop edge of x351, so 18 px are lost:
the headline reads "aját szabályaid" and the wordmark "elhom.eu" on every phone.
Nothing re-cropped on Facebook (the task's fence). The fix is build.py's safe
area (<=938 px, ~900 for margin) plus the measured 172 px centred phone profile
circle, then a hand re-upload. R-919 opened; R-918 closed and moved to
CLOSED-ITEMS with the recipe that made the check possible.
Meta's help page is wrong about Meta's own rendering: it states 2.4:1 for the
mobile cover where the header measures 1.504:1, so this session's first-pass
arithmetic -- explicitly labelled arithmetic, not a check -- under-predicted the
crop about fivefold. That is recorded rather than quietly deleted.
Also: the evidence secret scan needed --exclude=README.md, because that README
quotes the search strings and was matching itself (4 false EAA hits, 1 false
access_token); with the exclusion, control 1 -> 0 and no real hit. And the
Business & legal section header was already miscounted before this session
(said 9/P2 4, actually held 10/P2 5) -- corrected; five other section headers
drift too and are named in the report, left for a session that owns the register.
The DooPlex gate run at 8664cbda is rc=0, all 18 gates OK; the Windows run's two
failures are platform artifacts (fcntl, symlink privilege, C:/E: mount, cp1250
console) and the deliberate workspace-CLAUDE.md divergence.
CI gates.yml #846 for 8664cbda78: Success, 4m39s. The Gitea API refused every
credential in the store (401), so the run was read from Gitea's web UI, which
serves the Actions list unauthenticated; /actions/runs/846 redirects to
/actions/runs/1573, R-417's index-vs-id offset again, so both numbers are on the
screenshot.
STATUS: the Facebook section rewritten for what is now live, the open-items
count corrected to the counted 140.
Ran marketing/facebook/TASK-page-setup-windows.md from the Windows workstation
through Claude in Chrome. Evidence in
documentation/audits/facebook-page-setup-2026-10-08/, report in
REPORT-facebook-page-setup.md.
Done, each read back from a different channel than the edit: the intro is
COPY.md §1 (Graph `about` hex-equal, 99 chars); the action button is
"További információ" to https://felhom.eu/; the Messenger welcome is COPY.md §3
(hex-equal) and the automation is on; the username is felhom.eu, so the Page
answers at facebook.com/felhom.eu.
Not done: COPY.md §2 has no field to go in — Facebook's current Pages
experience has no long-description field and the Graph `description` is null
and unwritable with the robot key's scopes. R-917, four options, operator's
call; no Hungarian copy was shortened.
Phase A read Meta's size page first-hand: it carries none of the 820x312 /
640x360 figures our README asserted, and its own two ratios contradict the file
it recommends. README's grade and comparison rewritten; what we build is
unchanged.
Phase C measured the computer width (cover whole, no crop, profile circle 16 px
clear). The 390 px phone check was NOT performed: narrowing a desktop browser
never gives Facebook's phone layout. R-918.
Nothing posted; no ad, no boost, no Meta Verified; the Meta app stays in
development mode; no host, guest, box or hub touched.
