H2: the benchmark budgets were calibrated on the author's sandbox with a
1.14x margin — the review runner measured tsFullCandidateMs at 169-171 ms
against a 100 ms ceiling. Budgets now keep the spec's 2-3x allowance over
the SLOWEST observed machine, and the benchmark runs as a step of the
Validate perf job on every push (it needs no browser and no bundle), not
only inside the weekly mutation gate.
M1: the promised AC1 backend test exists now and does what AC1 means: it
patches validate_junction_limits with a thread-recording wrapper inside the
real HA harness — on the event loop that would be MainThread — and proves
the verdicts survived the move (a clean write is accepted, a write adding a
spike is refused with junction_limit_angle). Spec revision 4 rewrites AC1
around this invariant instead of a fragile millisecond assertion.
M2: §4.6 equivalence is now behavioural on both sides (three boundary
fixtures each: as-is counts equal through-migration counts, TS and python),
and the parity suite gained the §7 boundary fixtures (exact 15°, exact
20 cm, the thickness-step filler run, exact 5 cm).
H1 was already closed by 7513f93d (the review ran on the previous HEAD):
check-docs is green on this tree — the screenshots and their manifest come
from one capture run.

Writing the §5 benchmark honestly exposed a cost the point measurements of
П1-П4 could not see: П5 recomputed the full junction topology and masonry
union PER ROOM — 4.2 s per candidate on the benchmark grid. Revision 3 adds
the shared-pass cut (one topology pass per check, the union only when
multi-wall nodes exist, and the resize path reusing its own preflight
artifact) with the measured numbers. Budgets in §5 already assumed the fix;
they are now achievable and proven by the passing benchmark.

r1-H1 was right twice: the rev cache never touched the candidate's migration,
and П4 is architecturally quadratic. Profiled instead of guessing: the money
is not in deepcopy (3 ms) but in _atomize (663k distance calls), and it runs
even for a document that already carries the current catalogue — 815 ms
python / 69 ms TS for a no-op migration. Two new cuts follow: §4.5 bucket
index for П4 (prototype: 372→44 ms, identical verdicts) and §4.6 current-
version documents are used as-is (an explicit revision of the "both sides
through one migration" wording, guarded by a new parity case: v9 input gives
the same verdict with and without migration).
r1-H2: AC4 now rests on the new benchmark that actually exercises the
junction code; benchmark_safe_resize is named as a non-proof. r1-M1: §9
adds the mandatory i18n/touch/risks/release sections.
Budgets in §5 are recomputed from measured post-fix prototypes with a 2-3x
allowance, including an honest row for the one-off cold legacy case.

Four cuts, zero verdict changes: the ws_config_set validator chain moves to
the executor, the previous-document violation counts are cached by
config_rev, П3 builds its node index once per check in both mirrors, and the
frontend baseline is cached per config epoch. A new benchmark with budgets
pins the class of regression (O(n²) returning) in CI.
Measured on dev 2c20f2dc: a 576-atom plan costs 2.8 s in the HA event loop
per config write today; the spec's acceptance bar is ≤50 ms of loop time.
