V6a: pass the stable devices array to resolvedLightSources — the WeakMap
cache is keyed by array identity, a spread guaranteed a miss on every
render in BOTH cards (full-card regression since beta.4).
V6b: the static wall geometry now carries the same non-enumerable
sourceFingerprint tag the full card attaches, so buildLightBarrierScene
takes the fast recutWallBodiesGeometry path on door state changes.
V6c: the static barrier-scene cache is an LRU of 8 per space (parity
with _lightBarrierPool) — a flipping door reuses both of its scenes.
V6d: enabledClip is cached by geometry fingerprint + disabled-room set,
with the full card's bbox prefilter for decor bodies.

A picked raster is now classified from its HEADER BYTES ONLY before anything
heavy happens: src/backdrop-probe.ts parses PNG IHDR (+colour type/tRNS for
alpha), JPEG SOF and WebP VP8/VP8L/VP8X at fixed offsets, never using a file
field as an allocation size; hostile or truncated headers collapse to
'unknown', which warns without numbers instead of passing silently. The
thresholds live in that module as the single calibration point
(WARN_DECODED_BYTES 128 MiB ≈ 32 MP, HARD_DIMENSION 16384 — the browser
canvas cap, DOWNSCALE_TARGET_PX 4096), derived from the desktop-Chromium
matrix now committed as demo/benchmark_backdrop_decode.mjs with a
conservative tablet margin documented in the spec.
The shared pick flow (src/backdrop-pick.ts) feeds BOTH lazy runtimes — the
editor space dialog and the onboarding first-space dialog — so the guard
cannot drift between them, and nothing of it enters the eager View graph.
Warn shows the real numbers and three actions; the reduced copy decodes
EXIF-aware, keeps aspect and alpha (PNG stays PNG, opaque becomes JPEG
q0.9) and flows through the ordinary planFile → upload path. Hard has two
phases with one outcome: beyond 16384 px only Cancel; a failed or timed-out
(10 s) reduce closes with a toast, clean staging and NO silent fallback to
the original the user just declined. SVG never reaches the probe. The safe
path swaps the manual byte-loop base64 for FileReader — half the JS-heap
peak on every upload, byte-identical output (parity asserted in the smoke).
Proofs: header-table units incl. a fuzz set of hostile headers and ±1
threshold bounds; smoke_backdrop_guard on the real bundle — zero decode
calls before the choice, byte parity of keep-original, a real 6200 px
reduce to 4096 for both alpha and opaque branches, cancel-only hard
dialog, both phase-2 failures (reject and hang under the test-only timeout
override), re-pick after refusal, SVG bypass; four registry mutants
(probe-always-safe, alpha-dropped, hard-demoted, phase-2 silent fallback).
Spec anchor corrected alongside: the server plan limit is 8 MB
(MAX_PLAN_BYTES), attachments are the 50 MB path — an 8 MB JPEG is easily
80-160 MP decoded, so the client-side guard stays the primary defence.

Add Deutsch across all card surfaces and backend flows, backed by the language registry introduced in #62. German loads as a fingerprint-checked page-shared locale chunk so EN/RU remain synchronous and the initial View budget stays intact. Root render gates prevent mixed-language flashes, retry once, and fail open to English. Extend parity, runtime, bundle, browser and visual coverage, plus contributor and user documentation.

Four independent cuts into the 2-4 hour full run, none touching the contract
"a mutant must turn its guard red":
- guardNeedsBundle: rollup runs only for guards that open the built bundle
(demo/ smokes, golden captures, bundle:sync) — 68 of 253 registry entries.
Unit and backend guards never read dist/ as a build artifact (verified
against every test that mentions dist/**: they read the git checkout or
synthetic files), so 185 mutants skip the most expensive step entirely.
- seedTestBuild + incremental tsc: the mutant worktree starts from the main
tree's warm test-build/ and .tsbuildinfo; tsc compares file hashes, not
mtimes, so the fresh checkout stays warm and only the mutated delta is
recompiled. This also speeds up the long guards that run tsc themselves.
- --changed[=range]: run only mutants whose patch files are touched by the
diff (origin/dev..HEAD by default). An empty selection is an honest success
with an explicit message — the full registry remains the pre-release
contract, per the workflow comment.
- --shard=i/n: deterministic interleaved slices; the workflow runs a 4-way
matrix, and a warm test-build step feeds every shard. Interleaving spreads
the expensive browser mutants across shards instead of clumping them.
Measured per mutant on this machine: unit 12-13 s (was ~50-70 s), backend
6 s, browser 32 s (unchanged — the bundle is genuinely needed there). Full
run estimate drops to ~70 sequential minutes, ~20 on four shards.
Unit coverage: guard classification on real registry shapes, a floor on both
classes so the split cannot silently collapse, changed-selection semantics,
and shard completeness/disjointness with an anti-clumping bound.

The owner's five limits as pure functions: minimum 15 degrees between
neighbouring rays of a node (a straight wall through the node is a 180 pair,
not a violation), at most 6 walls per node, a segment at least
max(20 cm, its own thickness), 5 cm clearance between non-incident nodes and
between a node and a foreign wall (a T-joint sitting exactly on that wall is
incidence, not a near miss), and a room interior of at least 25 cm2 after the
masonry is subtracted. Thresholds are absolute and do not scale with cell_cm.
newViolations() implements the spec's inheritance boundary: only violations
introduced by the write are reported.

Рисование прямой стены в несколько кликов оставляло по записи на каждый
отрезок. Швы невидимы, пока их не тронешь: выделение хватает кусок,
перетаскивание ломает стену пополам, толщина задаётся пофрагментно. У стен
комнат этого давно нет — `normalizeWallIntervals` схлопывает каждый сплошной
участок одной толщины. Независимые перегородки жили по другому правилу.
Новый чистый модуль `src/wall-merge.ts` даёт им то же правило:
- `mergeCollinearPartitions` сращивает соседей одинаковой толщины и
направления до неподвижной точки, но только там, где узел никому не нужен.
Узел остаётся, если в него приходит третья перегородка, стена комнаты
(стороной, а не только вершиной), колонна или конец сохранённого черновика.
- Направление выжившей записи канонизируется лексикографически: иначе одна и
та же физическая стена выходила то a→b, то b→a в зависимости от порядка
входа, и каждый host.t вдоль неё переворачивался вместе с ней.
- `applyOpeningMoves` переносит проёмы на выжившую запись: и авторитетный
`host`, и legacy-проекцию `x/y/angle`, которую рисует старый читатель
конфига (docs/CONFIG-COMPATIBILITY.md, #132). Проекция здесь не кэш —
канонизация направления разворачивает угол на 180°.
Рисование сращивает только свою цепочку и то, чего она коснулась (§8.6 ТЗ):
молча править чужие швы в стороне оно не вправе — для этого есть
«Оптимизировать планы» с предпросмотром, отчётом и отменой. Оптимизация
проходит по всему пространству без seed-ограничения и отдельной строкой
сообщает, сколько записей исчезло.

The order of config.spaces used to be whatever order the spaces were created
in, and there was no way back other than deleting a space and drawing it
again.
The gesture is deliberately narrow — mouse, editors only. The same tabs are
the primary way to switch spaces in View, where touch is first class, so a
drag there would compete with the tap that switches. Recorded in the spec as
"Touch editor: not exposed".
The part that needed care is not the drag. Position in the array feeds three
things: the marker placement fallback, the swipe neighbour and a positional
`floor`. So the write that stores the new order also writes down the
placement that used to depend on it: a marker with neither an explicit space
nor an area that names one gets the space it has right now. Both changes go in
one save; splitting them would leave a window in which markers move on their
own. The positional `floor` cannot be fixed from here, so the card says so
once.
