The Experimental folder gains a bless-india-posters row, provisional until
its bundle is in the tree (a missing bundle prunes the row, so nothing shows
before it lands), with its label in all 11 locales. Its root is a
natural-height page of poster cards, so a row may set scroll: the element is
then mounted unpinned at its natural height and the pane scrolls it, instead
of being pinned to the pane, which would trap the page's own content.
check:posterverse-shelf expects the row and the scroll set by name; its
self-test drops the row and drops the flag.
Re-adds the fork-leaders catalogue entries after merging the pilot
(the merge took the pilot's package.json; this restores the new gate's
registration in a separate, reviewable commit).
Closed, the folder sat mid-drawer under the one short Posters section with
empty space below, so it read as a caption with nothing under it and was easy
to miss on a phone. Open, its plugins show like any section's rows; a reader
can still collapse it. check:posterverse-shelf asserts the open default, and
its self-test plants a closed folder.
The samples arm is now a function the self-test can poison: with withholding
switched off, India (no sheet tier, no outlines) must fail as a sample that
cannot be drawn. Closes the branch the arm had no poison for.
India, the one large-sheet country, now prints at 5 x 8 ft only, so the
5.5 x 5.5 ft and 3 x 5 ft side-lane cards would have drawn India's 60x96 sheet
under their own label. They now sample the largest drawable countries (China
at 66x66, Sudan at 36x60) through the same shared sheet path, and their
details say that no country prints at this size today
(posterDesign.missing.noCountryAtSize, 11 locales). The 60x96 card keeps
India and stays withheld. check:poster-design-catalogue now checks every
sample: drawable, or withheld by countrySheet.js.
A host that serves the tree with Last-Modified and no Cache-Control lets a browser run its cached files for
hours. Measured: a typed-URL revisit after a deploy requested none of the gallery, the manifest or the bundles,
so a returning reader ran the old files, or an old manifest against a new bundle.
- The manifest is fetched with cache 'no-cache', so it is always revalidated (a 304 when unchanged).
- A fingerprint of the manifest (every bundle's integrity) is kept per tree. When it differs from the reader's
last visit, every bundle the browser already holds gets one conditional request before any tab mounts:
a 304 refreshes it, and a 200 is cancelled at its headers, which drops the stale copy. The plain <script>
that follows, the gallery's own or a composite's for its children, then runs the new file at the same URL.
- A version query is not used: loadScriptOnce keys its registry by the full href, so X.js?v= next to a
composite's plain X.js would run the bundle twice.
- A first visit with an empty cache costs nothing extra (only-if-cached finds nothing held), and so does an
ordinary visit with an unchanged manifest. The mount waits at most 8 s for the check.
A preset page loads only poster-sections.js, so a preset of a poster type
registered by another plugin's script (upg100-list) could only say No
posters. The generator now gives no presets to a type whose file is not on
the tree, and check:poster-sections fails on any such preset: 9 presets
remain (7 regions, all regions, configure).
The tree generator writes a page per preset but never deletes one, so the
dropped presets' pages (the 10 upg100 ones and countries-other) are removed,
and a new arm holds the built preset pages to exactly the presets.
