Run 34760156615 exposed stale registry witnesses under the honest #550 outcome taxonomy. Keep behavioural checks out of setup chains, retarget the preflight mutation to the editor host, and make the junction cache smoke exercise same-object in-place geometry changes.

Six normative cuts, both mirrors symmetric (spec revision 3):
- §2.1 node keys quantise to 1e-7 with the repository's canonicalisation
formula (sign·floor(|v|·1e7+0.5)/1e7, -0 normalised) — toFixed(6) keys
split one node into two on floating debris and produced two false П4
refusals on a legitimate resize (reproduced: -1e-8 vs 0). Node pairs
within 2e-7 of each other (raw coordinates) are ONE node, and the
node-to-wall incidence uses the same quantum.
- §2.2 a ~0° wedge IS a violation: two rays leaving a node the same way are
a duplicated or overlaid wall (a butt joint yields 180°, never 0°) — the
worst degenerate case was invisible while 0.5° was refused.
- §2.3/§2.4 the wall run is an iterative edge walk over the collinear
component: no recursion (10 000 atoms answered, not RangeError), no
silently dropped fork (the old .find lost every branch but the first),
O(E) by construction, and collinearity is measured against the BASE
segment's axis so an arc of 0.9°-per-atom pieces cannot pose as one wall.
- §2.5 an exception while judging the CANDIDATE refuses the write with the
junction.limit_check_failed toast (fail-closed, as the #278 guard); the
baseline branch stays fail-open by design and the smoke proves the
asymmetry by breaking only the second call of the deterministic pair.
- §2.6 the python mirror narrows its except on the candidate side only:
a genuine migration bug (TypeError) surfaces as an honest WS error, while
a previous-side bug keeps the wide "no baseline" fallback — the two AC6
cases pin the asymmetry so swapped sides turn a unit red.
Parity fixtures gain the new boundary classes (debris node, duplicate wall,
collinear fork); four new mutants pin the filter, the key precision, the
dropped branch and the fail-open hole.

The reviewer proved my behavioural claim false by running the stale-cache
mutant against the smoke: 11 vs 12 total calls — indistinguishable. Two real
defects hid behind that finding:
1. The cache keyed on _cfgEpoch, which ticks on every ACCEPTED PREVIEW —
the cache missed on every pointermove and the baseline was recomputed
~4 times per gesture (measured). The key is now the document identity
plus spacePhysicalGeometryFingerprint of its space: content, not a
counter. A preview overlay leaves the fingerprint alone; an in-place
structural commit changes it and honestly invalidates.
2. The smoke now counts BASELINE computations only (calls whose document is
_serverCfg) across two gestures with a commit in between, expecting
exactly 1 then exactly 2. A disabled cache lands near 20, an eternal
cache stays at 1 — every mutant class turns the smoke red, and the smoke
is now the mutant's guard alongside the source-contract unit.

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.

Measured what Resize itself already forbids: a room cannot be squeezed below
30 cm (two 15 cm walls), so П3 and П5 are unreachable through shrinking and
the gate merely fails closed there. П4 IS reachable on a fine grid, so the
smoke drags a real handle on a 2 cm grid: two rooms 10 cm apart, a 6 cm pull
would leave 4 cm between foreign nodes, the wall stops at 6 cm and exactly one
toast names the 5 cm rule.
Spec revision 6 records both the measurement and the two corrections it forces
on AC7a: a dimmed handle cannot express a per-step limit, and the plan is NOT
byte-unchanged — the allowed part of the gesture is a legitimate edit.

П3 measures the WALL, not the catalogue atom: a short filler segment that
compensates a thickness step (owner's fixture, 5 cm = (30-20)/2) is a legal
continuation of a long same-thickness wall, so the rule walks the maximal
collinear run through the shared nodes before judging the length.
Resize stops at the last allowed position and names the broken rule instead
of the generic "geometry cannot be saved"; the Thickness dialog refuses
through its own toast. Both channels are pinned by demo/smoke_junction_limits
plus three mutants (angle threshold, write barrier, degenerate apex bevel).
