Phase 5 item 1 asked for the overlap to be sized "by measuring the reader's
construction set against the writer's rather than by growing corpora blindly".
New lane `evals/construction_inventory` does that: it sweeps the writer's whole
parameter space (every RhetoricalMove x IntentTag x predicate x quantifier x
tense x aspect, both public entry points, 32292 cells), quotients it by the
reader's OWN function-word skeleton, and comprehends each construction under
three vocabularies.
writer constructions 1739
reader constructions 19 (mint-site AST-guarded)
overlap, faithful 6
accepts but MIS-READS 22
refuses 1711
vocabulary-dependent 0
Faithfulness, not acceptance, is the criterion — and that reverses two claims
in the plan's §6 RESULT, using a metric that was already on the page:
* g_read_rate is 1/293 but **g_args_rate is 0.0**. The one surface that "reads",
`all molecules are defined as compounds`, is comprehended as
`subset(molecule, defined_as_compound)` — the reader chunked the writer's verb
phrase into a class name. It accepted; it did not comprehend.
* "one construction wide" was wrong both ways: zero on that corpus, six over the
writer's actual output space. A corpus cannot report an inventory's size.
Three findings re-order Phase 5 item 1:
1. The reader FABRICATES on 22 constructions — neither reads nor refuses.
`every dog is a mammal` -> member(every_dog, mammal);
`furthermore, all dogs are mammals` -> asserted(furthermore).
Both are ordinary user English, not writer artefacts. Root cause: _RESERVED
lacks the function words the writer emits, and _parse_propositional accepts
any single token as a fact.
2. It reaches SERVED output. deduction_surface recites
`Given: furthermore; p implies q; p.` — a premise the user never stated — and
chat/runtime.py realizes declarative turns into the held self, so a
fabricated atom is vault-writable. Widening the inventory first would widen
the fabrication surface with it.
3. ADR-0265's defect class survives inside ADR-0265's designated owner of clause
grammar: the four aspect arms of _inflect_predicate bind `negated` to a
wildcard and never read it, so `dog has been defined as mammal` serves both
the assertion and the denial (10530/16146 points). Unreachable today — no
producer sets aspect — so a loaded gun, not a casualty. It survived because
ADR-0265's invariant is structural (is `negated` threaded?) and cannot see an
arm that receives the flag and ignores it. A behavioural sweep can.
The two fixes are written already, as the mutations that turn the defect pins
red. They are NOT applied here: they change what CORE comprehends from user
input, which is a serving change on the truth path — authorization-gated, ADR
first, on the ADR-0261 §5.1 refuse-don't-drop precedent.
Guards, so the tables cannot rot: reader constructions are pinned to an AST
count of the reader's 10 mint sites; the declared tense/aspect axes are pinned
to _inflect_predicate's match arms; the committed corpus is pinned to the
fillers in use. 14 pins, 13 mutations observed RED.
