Apply re-validated the preview token after both halves were durable, so a
TTL that lapsed during the write, or an eviction by a newer preview of the
same user, answered "preview expired" for a plan that was already replaced
and withheld both update events. The token is now simply spent after the
commit; validity is decided once, on entry under write_lock.
Route runs dropped by drop_unknown_routes never reached the store unless a
marker happened to be orphaned in the same pass; an idle robot kept them in
memory only and a restart brought them back. The drop now happens under
_refresh_lock, leaves with the orphan transaction or with an immediate
write of its own, and rolls back like #335 when the store refuses.
Tests: HA harness for both apply races and a live config/set route drop,
recorder stubs for the four durability cases; five mutants caught by the
standard runner.

Tooling: requirements_test.txt becomes the single source of backend CI
dependencies; pyproject.toml configures ruff (E/F/B/I, E501 excluded by
decision) and mypy strict for a grow-only allowlist of six pure modules
(junction_limits annotated to pass). The 42 substantive ruff findings
are fixed — the B023 loop-variable closures bind their variables as
parameter defaults instead of hiding behind noqa, and every remaining
noqa carries a reason (guarded by a test).
Errors: const.ERROR_CODES / ERROR_CODE_FAMILIES formalise the stable
contract; the scanner test proves every emitted code across BOTH paths
(send_error literals; class attrs, literal and variable-passed
MarkerControlError codes, f-string families) is registered and has a
localized message — 22 missing backup.error.* keys added in all four
languages. invalid_passage_fields / invalid_partition_opening_jamb_margin
ship structured JSON details (legacy format read-compat for one beta),
and _errText renders code-first: unknown codes localize, raw English
messages go to the console.
CI: the backend job lints with ruff, refuses a silently skipped HA
harness (import + collect threshold), measures branch coverage over
pure+harness, fails below the committed baseline and uploads
coverage.xml. quality_scale: docs-troubleshooting/examples honestly
done, test-coverage/strict-typing carry staged progress.

#340/#356 made expected_rev mandatory for config/set and layout/set over a
non-empty store — an honest protection the release notes sold only as a
stale-tab guard. A third-party script writing plans directly cannot infer
from "protects from stale tabs" that it must now read the revision first.
Both changelogs gain an explicit breaking-for-external-writers entry with
the read-then-write recipe; ARCHITECTURE.md's WS contract section extends
the #340 paragraph with the cycle external clients must follow (get rev →
send expected_rev → on conflict re-read and retry); and both conflict
messages now carry the actionable hint for scripts — "include expected_rev
from houseplan/config/get / layout/get" — alongside the tab-oriented
"reload" advice. The backend tests pin only the "revision is required"
substring and stay untouched.

The owner's decision (2026-08-28): optimize is one of the two commands a
client can use to write arbitrary geometry, so it validates its candidate
against the stored document exactly as config/set does — inheritance counted
per rule (repairing a legacy plan with violations still passes; #329 AC10
already proves an honest optimization adds none, so the gate is a no-op for
legitimate flows), while a crafted payload is refused with the stable
junction_limit_<rule> code the except list has been ready for since #329.
The call lives inside the existing executor function, and a successful
optimize refreshes rt.junction_baseline with the candidate's counts so the
next config/set inherits from the cache (#330 §4.2 symmetry).
Import and backup restore stay OUTSIDE the gate on purpose — #329 §3
promises a restore is never blocked. The module docstring stops promising
more than the code does, and spec #329 §5 records the perimeter and the
trade-off explicitly: a crafted import can persist violations, but they are
inherited, never legalised as new ones.
HA tests pin AC1 (crafted spike refused, stored config and rev
byte-unchanged), AC2 (echo-optimize of a stored plan that already carries a
violation passes) and AC3 (the follow-up config/set takes its baseline from
the cache — observed through a recording wrapper). The
junction-limit-optimize-unguarded mutant turns AC1 red through the
backend-test-guard convention.

Six cuts, zero verdict changes (spec §3; equivalence pinned by units, the
parity suite and the smokes):
- §4.1 the CPU chain of ws_config_set and ws_plan_optimize runs in the
executor; write_lock still serialises writes, only the HA event loop is
freed (2.8 s of blocking per 576-atom write before).
- §4.2 the stored document's violation counts are cached on the runtime by
rev (store.py junction_baseline); a repeated write never re-judges
`previous`. validate_junction_limits takes baseline_counts and returns the
candidate's counts to cache after a successful save.
- §4.3 П3 builds its node index once per check in both mirrors
(289→11 ms TS, 285→~50 ms py).
- §4.5 П4 uses a bucket grid with the threshold as cell size in both
mirrors (104→19 ms TS, 372→44 ms py); pair enumeration switches to
lexicographic order — same verdict set, equivalence pinned against a
brute-force oracle on cell borders.
- §4.6 a document already carrying the current catalogue is judged as-is:
a no-op re-migration cost 815 ms py / 69 ms TS. Legacy documents migrate
exactly as before (the #329 H1 test stays green).
- §4.7 П5 shares one junction-topology pass per check and pays the masonry
union only when multi-wall nodes exist — and the resize path hands over
the preflight's own artifact, so a pointermove never builds the union
twice (4.2 s → 88 ms full candidate on the benchmark grid).
The frontend baseline is cached per (document identity, config epoch): ten
pointermoves make N+1 limit computations, not 2N — pinned by the smoke on a
real pointer gesture.
demo/benchmark_junction_limits.mjs (npm run benchmark:junction-limits) pins
the budgets for both mirrors: TS full candidate ≤100 ms (measured 88), py
warm validate ≤250 ms (measured 45), cold legacy ≤3.5 s — that path is
one-off and lives in the executor.

custom_components/houseplan/junction_limits.py repeats П1-П4 for the write
barrier in websocket_api, counting per rule so an inherited violation still
round-trips, and raises JunctionLimitError with the stable code
junction_limit_<rule>.
П5 is deliberately not mirrored — it judges the rendered wall bodies, and a
second mitre/inset pipeline in Python would drift more dangerously than the
rule it guards. Optimize stays outside the check for the same reason migration
and import do: it repairs existing geometry.
test_parity_with_the_frontend_checks feeds identical fixtures to the TS
functions and to this module and demands the same verdict, so the two
implementations cannot silently diverge.

Диалог «Оптимизировать» при отказе перечисляет причину по каждому
пространству (7 значений OptimizeGeometryFailureReason получили RU/EN
строки), даёт «Скопировать диагностику» — JSON-блок с origin: runtime,
версией карточки, отпечатками и классами исключений (граница приватности
checkOptimizeGeometry; privacy-тесты дополнены позитивной проверкой) — и
пишет одну структурированную запись в dev-лог (дедупликация по fingerprint).
При недоступном clipboard блок раскрывается прямо в диалоге.
Совет «обновите House Plan» больше не безусловный: websocket
houseplan/config/get теперь возвращает integration_version (бэкенд-тест),
и подсказка показывается только при реальном расхождении с версией карточки;
старый бэкенд без поля — подсказки нет.
Три новых мутанта (потеря причины в диалоге, блок без reason, отключённый
dev-лог) — краснота каждого проверена исполнением; смок
smoke_preflight_diagnostics на dev падает.
