posters/*.webp is not shipped by default (42MB; bundling pushed the tree to 80MB,
git-packed to 57MiB, and the catalog rejected the push). The DOWNLOAD path has
handled that since d154a76 — PosterWall fetches posters/<id>.html and rasterises
it in the browser. The PRINT path did not: it handed an <img> a url it never
checked, so on a default drop the SAME poster downloaded fine and PRINTED as
"Poster not available yet." That is the bad first impression
IDEA-POSTER-EXPORT-404-ON-DROPPED-FOLDER-TRADEOFF called out by name.
Three things were missing; all three are here:
1. printPoster now climbs the same ladder as the download path — probe the webp,
and only on a miss fetch the .html, rasterise, and verify PIXELS before opening
the dialog (an SVG in an <img> is an isolated document: a lost stylesheet prints
a black square with no error). Blob urls are held until unmount, not revoked at
print time — the preview <img> is still reading from them.
2. publish-html.mjs wrote into public/assets/posters, which is a GENERATED MIRROR
that every `bun run tree` rmSync's. Its output never survived, which is a large
part of why the fallback still had no input months after it shipped. Retargeted
at data/posters, the tracked source the mirror is made from.
3. bundlePosters is one boolean over a directory holding 40.9MB of rasters AND the
28 sources, so it could only ever ship both or neither — and "neither" is what
made both full-size paths 404. posterSources:true ships the sources without the
rasters, the combination that was previously inexpressible. DEFAULT UNCHANGED:
28 sources are 27.9MB raw (6.9MB packed, measured with pack-objects), real
weight in a published tree that needs a deployment decision, not a silent one.
VERIFIED AT THE RENDERED LAYER, not by reading source. check:poster-print-fallback
clicks the real control with every posters/*.webp ABORTED at the network layer —
the default-drop condition forced rather than hoped for — and asserts the HUD
enters "generating the poster" and settles clean. Mutation-tested: removing the
fallback produces 4 failures including "no posters/*.html was fetched". The other
branch is verified too — with a webp present it is used directly, zero html
fetches, no rasterise — so the extra probe is paid only on a miss.
★ THE GATE WAS WRONG THREE TIMES FIRST, each time blaming the product for a
harness fault, which is why it now asserts the HUD instead of an internal:
- it matched /print/i, but the control reads "UPG prayer poster" — the product
names the ARTEFACT, not the action;
- it patched Document.prototype in the PARENT realm while openPrintFrame writes
into the iframe's own;
- openPrintFrame calls doc.open() AFTER append, and open() RESETS the document,
discarding a write patched at append time.
Through all three the .webp/.html request counters looked corroborating, because
the wall loads both by itself. The HUD is what a user sees, survives a refactor of
the print internals, and cannot silently miss.
The 28 poster sources are committed because the fallback has no input without
them. city-* posters are deliberately NOT covered: they fetch OSM street tiles at
generation time, so they are not reproducible offline and their rasters must stay.
posters/ (42M webp set the poster walls fetch) and tables/ (the merged served
table set — its index.json is the merge; per-profile data/tables remain the
build-time sources) now live in data/ with build copy-steps. Byte parity
verified; served paths unchanged. public/ is now FULLY regenerable — every
source-of-truth folder has a home outside the web-root.
