The physical bodies, the wall union pool, the inner room contours and the
clean floor carried the global config epoch in their keys. Every edit of
any floor bumps it, so after one edit every other floor was cold again:
in large-house the first visit to an untouched floor rebuilt its wall
union and paid ~0.7 s flat / ~0.65 s 2.5D instead of ~40-55 ms.
A floor's geometry reads only its own config record (spaceModels) and
constants, so the key is now a content fingerprint of that record
(src/floor-geometry-key.ts), remembered per epoch and per record object.
The geometry also reads the current floor's config next to the model it
is given; when those records differ the key covers both. The live resize
preview is its own record, so preview frames get their own key; the
editor runtime seeds the pool and re-keys the bodies through the same
reader. The stairs editor no longer clears the clean floors of every
floor: the stairs are part of the floor's record.
The #735 switch-cycle guard now also sees the union pool and the inner
contours (optional members of the large-house card contract, so an older
comparison bundle reads 0). smoke_floor_geometry_cache proves the warm other floor and the
invalidation against an independent card (multi-floor push with shared
walls, a stair, a resize preview and its cancel); two mutants guard it.

Validate on the conveyor's rebase eb439e81 failed preflight: the branch
changes visual sources (stairs), so the screenshot check is strict on it,
and the fingerprint was stale against the moved dev (#739, #742, #759).
The branch is rebased onto b84465e5 (inventory counts merged with #742:
lifecycle 89, total 204/200) and `docs:accept --identical` re-captured
all 11 frames: pixel-identical, only the source fingerprint moves.

A floor with stairs pays for them on every switch to it: the stair layer
is emptied on other floors, so Lit recreates every symbol on each return
and the browser lays out and paints it again. With 250 stairs (the
large-house fixture, the per-floor limit) that was 2,875 SVG elements and
about 40 ms per entry locally; each stair carried 3-7 separate tread lines
with four bound coordinates each.
The treads of one stair are now a single <path class="hp-stair-tread">
with one `M a L b` subpath per tread, in geometry order and with the
numbers the lines carried. Treads of one stair never overlap (straight:
parallel, >= 20 cm apart; spiral: inner ends >= 6.7 cm apart at the
3.6 cm stroke), so the path paints the same pixels at any opacity. The
outline points and the tread data are built once per cached geometry
object (cachedStairMarkup, weak keys), not on every render. The View and
plan-editor layers share the strings; outline, hit polygon, trapezoid,
arrow, attributes and handlers are unchanged. Floor 1 of the fixture
drops from 4,210 to 2,960 elements.
Witnesses: the unit test for the path data and its cache, and the
smoke_stairs markup checks in View and in the plan editor, are red on
dev. The stairs-view-tread-lines mutant restores the View lines.

Five places still described the pipeline as it was before code that is
already in dev:
- the S3 hint of the task packet told the author to push the branch, while
the spec lives in the issue body (§2.3, #517) and nothing is pushed
before S5 (§11.8);
- process-gate printed «FAIL п.9 Gates: light» for a trailer nobody writes
or reads, while §10.2 item 9 is the unimplemented release:prerelease
verdict check. The check is removed; a contract test ties every RULES key
to an implemented item of §10.2 and every finding number to a RULES key;
- §10.4 item 4 demanded a heredoc in run:, while #723/#730 and their tests
demand the opposite: commit messages echo line by line into a file,
comment and summary texts come from code;
- the ship merge comment, AUTHOR.md, REVIEWER.md and AGENTS.md named only
the pre-beta document, though since #727 the night reads ship code first;
- the nightly publication committed «docs: ship review for nightly …
перед бетой» with the beta step's Issue: #696. It now has its own
subject (the document name), body and Issue: #727; the beta message is
unchanged.
The browser-guard inventory note still said growth above 200 fails
mutation-gate --check; since #699 it is a guideline and --check warns. Its
counts now match the inventory: 205, lifecycle 90.

`.room { transition: 0.12s }` interpolates a room's colour and its
fill-opacity / stroke-opacity independently, and the visible opacity is their
product. The states without a fill kept their alpha in the colour with the
default opacity 1 (.overlay transparent, .yard rgba 0.14, .outlined rgba
0.06 / 0.55, .picked rgba 0.25), while .styled writes an opaque colour plus
fill-opacity: var(--room-fill-op). On a change between the two on the same
node one half rose while the other fell, and mid-way the room was darker than
at either end. Opening the space settings on a floor with no fill (the dialog
shows "no fill" as its own colour at alpha 0) flashed every room grey for
~0.1 s, 0 -> 0.241 -> 0; cancelling the dialog after a preview, entering and
leaving the plan editor briefly darkened the fill (0.18 -> 0.317 -> 0.06).
Every .room state now writes an opaque colour plus *-opacity, and
transparent only together with a zero opacity. The transition itself,
.styled and the --room-* variables are unchanged; the space card takes the
same styles. The resting paint is the same: the witness records each state's
colour and visible opacity as dev drew them, and screenshots of seven resting
states (View without fill, with fill and borders, plan editor, room picked for
a merge, yard with and without borders, yard in the plan editor) are
pixel-identical to dev outside the plan editor's tool hint, whose text shifts
by a sub-pixel between runs on dev too.
Witness: new demo/smoke_room_fill_transitions.mjs, deterministic. A
MutationObserver pauses the room's transitions at their first frame right
after Lit commits, and the smoke seeks them through 0..120 ms in 15 ms steps.
Red on dev: fill overshoot 0.241 / 0.125 / 0.137 / 0.134 on the four paths,
stroke 0.241 / 0.242 on the first two. A real colour change of the same room
still runs a fill transition (catches `transition: none`).
A card-mod rule that sets only `fill` on an unfilled room now meets
fill-opacity 0; CHANGELOG and STYLING-HOOKS say to set the opacity with the
colour (the values are generated, STYLING-HOOKS §3.3).
