feat(rnd): ADR-0252 §5 run to a verdict — NO-GO, and the two prior GOs are void
Track A of docs/assessment/50-execution-plan.md §6, executed under its own
protocol. Criterion pre-registered at dfc394d2 (that commit carries the
thresholds as importable constants and NO results); this commit carries the run.

VERDICT: NO-GO. Full credit by ADR-0252 §5.4's own terms.

53 cases, 1378 pairs, 0.0% non-convergence — no exception contributed to any
number. RS-A (structure-only) separates perfectly, AUC 1.0000, margin +0.0867,
and fails structure-sensitivity. RS-B (attribute-bearing) fails all three.

The mechanism, measured rather than argued: the similarity quotient that would
deliver attribute-invariance is the same quotient that annihilates structural
contrast. An add-vs-subtract minimal pair — one entity, identical numbers, one
relation kind changed — aligns at residual exactly 0.0, its two configurations
being related by a PROPER rotation about e1. Sweeping the attribute weight
(committed as diagnostic_sweep), structure-sensitivity fails at every setting,
and every regime where the SME property survives is a regime where attributes
contribute nothing: AUC 1.00 -> 0.97 -> 0.83 -> 0.69 as they begin to matter.

Scope stated narrowly: this refutes H1 for embeddings that encode role-structure
as point positions aligned by conformal Procrustes under similarity. The
argument is about the quotient, so it generalises across that class; it does not
refute every Cl(4,1) representation, and it does not touch the symbolic
structure-mapping lane already in evals/structure_mapping/.

Two findings that were on nobody's list:

N-8 — the experiment was NOT unrun. rnd/sme-experiment-v2 @ 96e5f468 is titled
"Verdict: GO" and rnd/structure-mapping-experiment @ fc9d0c14 carries an earlier
one. Neither survives inspection: attempt 1 leaked the S1-S4 label into the
embedding; attempt 2 was blind and then took its separability from
`except ValueError: res = 1000.0` — a solver exception counted as a distance —
on a corpus 46/51 of which is outside holdout_dev/v1 with nothing marked, with
duplicate graphs, colliding ids, and an extractor that was never committed. The
register, the plan and the ADR all read the same absence and inherited the same
error for nine days. A branch tip is not a record.

G-21 — the math reader returns a selected graph for 5 of 500 holdout_dev/v1
cases (1.0%), all one skeleton; 24/150 on the public lane. That is why §5.1's
four-structure corpus is not extractable, and it is a sharper measurement of the
comprehension frontier than G-3's construction count.

Registers updated: G-1 carries the verdict, H-10 confirmed and discharged, G-21
added, plan §0 gains N-8, Track A closed, synthesis frontier 2 rewritten.

Pins: tests/test_adr_0252_s5_blindness.py, each observed red before green
(label leak and duplicate-graph sabotage both caught).

Off-serving — evals/structure_mapping/adr0252_s5/ is imported by no serving
path, emits no answers, and changes no flag.

[Verification]: 797ebad5 + this branch — `uv run core test --suite smoke -q`
641 passed in 199.76s; `uv run ruff check` clean; report regenerated after lint
with an unchanged digest.
