Why capability has not moved despite everything being implemented, answered by
measurement rather than opinion, at 0e1be8be:
F-A The serving path is 100% symbolic. reader.py (490), proof_chain (3,916),
both surface composers: zero geometric references. All served capability
comes from a template parser feeding an ROBDD engine.
F-B The reader INVERTS its own ratified design. ADR-0252 §2 stage 1
prescribes containment/transfer/accumulation/comparison and bans
surface-slot regexes verbatim; the implementation is surface-slot
regexes over categorical/member/ordering/propositional. Corpus agrees:
1.28% read rate, possession/transfer/quantity absent, if/then (0.1% of
sentences) holding 21% of the inventory.
F-C Template architecture cannot produce chunk lifts — each construction is
one hand-fitted rule; generalization is zero by construction. This is
why lifts have only ever arrived as overfit slivers.
F-D Geometry does exactly two cognitive jobs and both are stranded:
salience->attention (bypassed by every licensed lane) and
relation_compiler's Hamiltonian ground-state solver (off-serving,
behind a 1.0% math reader). Real geometric computation exists — it
"NEVER evaluates scale*input+offset in Python" — and nothing feeds it.
F-E The §5 NO-GO killed alignment-on-points-under-similarity. The
composition branch — relations as OPERATORS, meaning as composition,
the pattern relation_compiler already embodies — was never tested.
Plan: docs/plans/2026-07-28-perception-arc.md. Phase 0 pins the 1.28%/1.0%
read-rate floors as the metric the arc is accountable to. Phase 1 is a
§5-shaped pre-registered GO/NO-GO on hypothesis H2 (compositional
core-primitive reading over operator encodings; NO-GO branch declared: a
principled compositional grammar instead — either verdict exits the template
treadmill). Phase 2 builds ONE perception layer as combinator core + declared
construction lexicon, so coverage growth is table rows, not parsers. Phase 3
reconnects the Hamiltonian corridor to serving through the now-honest licence
machinery. Phase 4 deletes what earned it: G-3's template-widening program
superseded, curriculum-serve machinery parked. Phase 5 prepares the ADR-0252
amendment and the use_salience ruling for one-word decisions.
Explicitly untouched: core/physics, the algebra, the reliability gate, the
ledger discipline — correct and load-bearing. The enumerative reader stays
serving until its replacement proves out: supersession-in-place, per the ADR's
own preserved rule.
G-24 registered Tier A. G-3 as previously specified is superseded, recorded in
the execution plan's closing addendum rather than silently.
