build.py believed a phone shows 640x360 of the cover. It shows 412x274 =
1.504:1 -- the full height and only the centre 938 px of 1640, 351 px off each
side. PHONE_HDR = (412, 274) now drives CW_PHONE, so SAFE is (391,40)-(1249,584),
858 px wide with a 40 px margin inside each crop edge.
QUIET is no longer one formula for both circles: the computer circle is
left-anchored, the phone circle is CENTRED and hides only its measured box
(637,369,393). The old shared formula, applied to a centred circle, would have
blanked everything from x 0 to x 1054 below y 345.
Every cover draws in a derived BAND (408,48)-(1249,340), and a cap check holds
each headline's capital at >= 4% of the cover height; A/B/C come out at 45, 45
and 37 px against a 25 px floor.
RED-PROOF, and it is permanent: control_old_window() runs on every build and
draws the headline where the old assumption put it (x 328); the check must
reject it. The phone's crop edge is x 351, so 23 px were cut; the measured safe
edge is x 391. Against the covers as committed at a76207945e the new check
convicted 3 of 3 -- A 23/22 px past the left/right edges, B 63/58 px plus 1017
content pixels under the phone circle, C 63/82 px plus 1778.
Covers redrawn inside the band: A one centred line; B the home motif scaled
with two tiles moved into the lower-right strip, the one area below the band a
phone still shows beside the profile circle; C the dashboard screen 470 -> 370
px so frame and base fit. preview.html shows the phone panel at the measured
938x624 with the centred circle and no longer claims 640x360.
Profile pictures untouched -- sha256 identical before and after, and not in the
diff. Built on DooPlex: the PNGs are byte-reproducible there (Pillow 11.1.0) and
not across Pillow versions; the README now says so.
R-919 is VERIFY, not closed: the geometry is measured on ONE emulated device in
the mobile website, so the operator's check in the Facebook app is the
acceptance. Nothing uploaded, no Graph API call, FACEBOOK_API never read.
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.
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.
build.py (Pillow, site tokens + Plus Jakarta Sans) with in-build checks: profile circle (today's shape 6823 pixels
outside, new 0), cover safe area and profile-circle clearance, sizes read back. COPY.md: intro 99/100, long
description, Messenger welcome, three first posts, each claim traced to the website. R-914 gets the listing-based
removal proof and the picture-API tasks; R-915 the footer-link note; R-916 the logo's vector master.
