vh bf351a26d1 feat(u7): filename groups — the last v1 unit, and a table that did not reproduce
Completes U7 with its fourth component: a jump-to-group rail derived from
filename prefixes, replacing the subfolder sections ROADMAP named. The scope
departure was ratified by the operator 2026-09-22; this commit deletes
test_no_group_rail_is_shipped_yet, the guard that held it back, in the same
change that builds what it guarded against.

All seven v1 capabilities are now landed. The 1.0 cut is a decision, not a
dependency, and it is the operator's — no version bump here, because a commit
is not a release.

THE RULE CHANGED AT IMPLEMENTATION, ON MEASURED GROUNDS. The contract specified
`strip ONE trailing run of digits`; run against the live set that yields 24
groups for sindra-bakeoff's 40 images and 27 for sindra's 30 — a rail with a row
per tile — because it keys on the END of the stem, where the instance number
lives. The contract's own table claimed 5 and 1 for those two booths and neither
reproduces; the numbers are reachable only by two OTHER heuristics, so the table
that justified the design was assembled from more than one rule. Its own worked
example contradicts it in plain sight.

The shipped rule keys on the first separator-delimited segment, where the family
lives, destemming only when the stem has no separator at all — so `ac01` -> `ac`
while `v30-seed8302` and `v35-seed8302` stay apart. Re-measured across all 17
live booths; the table is in the contract.

INV-3 GAINED ITS SECOND DEGENERACY. The contract guarded one group for
everything (sc-iso-spread: DSC0001-DSC0006). The live set's actual failure is
the opposite — pewpew-ui-brief yields 23 groups for 34 items, dfa-concepts 13
for 20 — and the contract as written would have shipped a rail that is a second
copy of the grid. The rail now renders only when grouping is informative: two or
more groups, and the middle group holding more than one item. That predicate
gets all 17 booths right.

Grouping is a VIEW. The grid stays sorted(rel) and the zoom ring stays that
order filtered to images; the group fixture interleaves across subdirectories
precisely so a (group, rel) re-sort goes red. Groups are derived from the
RENDERED list, not the full gallery, so no anchor points at a filtered-out tile.

booth/items.py       _group_of + Item.group, derived in the resolver (INV-1)
booth/app.py         _groups() builds the rail rows; build_gallery carries it
booth/templates/     the rail-groups nav and its CSS
tests/               +16 tests; 639 green

Every new falsifier was proved by running its defeating change (12/12). Three
were vacuous first time out: one fixture's positional order happened to be
alphabetical, one assertion miscounted elements, and the harness itself
certified a broken test twice — no green baseline, and byte-identical mutations
silently defeated by the pyc cache's one-second mtime granularity.

vh ce598b3cf6 feat(items): one item record, so an annotation survives the zoom
The operator reported that zoomed-in images lose their annotations. That was
never a rendering bug. Three functions independently walked a booth and derived
overlapping subsets of the same facts -- build_gallery (kind, caption, blur,
doc), booth_view_file (kind, doc, image ring) and list_booths (kind counts,
cover) -- and the zoom route's subset was the smallest. Caption resolution lived
inside build_gallery's loop and nowhere else, so there was no code path by which
a caption could reach the zoom template. It was never sent.

booth/items.py is now the one truth: booth_items() returns the full record --
rel, kind, section, caption, blur, doc kind, size -- and the gallery, the zoom
view, the doc view and the index all read it. Patching view.html would have
fixed the symptom for images and left the next surface starting from the same
missing truth.

Two things fall out of the consolidation:
  - the index and the booth page now agree on what an item IS. list_booths
    counted every non-dot file, so an A/B pair with two caption sidecars read
    as 4 items on the index and showed 2 tiles when you opened it.
  - "section" (the item's subfolder) is computed and carried but nothing renders
    it yet. That is deliberate: it is U7's whole input, and shipping the field
    now makes U7 a template change rather than a resolver change.

Doc bodies are NOT rendered by the resolver -- the index touches every booth on
every page load, and rendering every markdown file in every booth would be the
price of that convenience. render_doc_body is a separate step for the one
surface that inlines them; an invariant test monkeypatches it to raise and
loads the index.

Verified beyond the suite, because this repo has shipped two dead controls that
every test passed: the caption was measured in a real browser at 1280x41 px,
visible, with elementFromPoint at its centre returning the caption itself.
layout-probe reports all controls hittable across index, gallery, zoom and doc.

192 tests pass (173 before, 19 new).
