From the mandated lookback audit of the composed R0→R1→R1c→OOV surface:
- wrong=0 HAZARD (medium): realize_quantitative trusted equation admissibility it
never checked. `comprehend_quantitative` runs real check_admissibility, but the
type does not enforce it, so a future non-reader constructor could slip a
dimensionally-incoherent 'pending'/'refused' equation into the held self (then
surfaced as-told by DETERMINE). Now RE-ASSERTS admitted-status defensively ->
NotRealized("unadmitted_equation"); docstring corrected to match (no longer claims
the type guarantees it). Bite test via a hand-built pending-equation graph.
- Defensive: wrap binding_graph hashing -> NotRealized("unhashable_structure") so a
future numeric field is a clean refusal, not an uncaught TypeError mid-write.
- Coverage (the obligations now bite, not decoration): unadmitted_equation,
not_a_quant_comprehension, no_bound_fact, grounding_failed (monkeypatched probe),
cross-substrate coexistence (meaning_graph + binding_graph in one vault — recall
isolates, structure_keys differ), and the negated_relation refusal (hand-built,
since the reader encodes declarative negation in the PREDICATE not rel.negated).
- Drift: R0 idempotency test now names the actual dedup key (structure_key, not
content_hash); scope doc notes #591 made OOV placement injective (the §0/§1
non-injectivity finding describes the pre-#591 substrate).
Note: the lookback flagged negated_relation as a high reachable-untested hazard, but
verification showed the reader never sets rel.negated=True for declaratives (it
refuses "X is not a Y" or uses some_not/disjoint predicates) — so it is a defensive
branch, tested via a hand-built graph. Green: 35 realize + ruff clean.
R0 keyed a realized fact by its subject's field versor, which is NOT injective:
two facts about one subject embed to byte-identical versors and collide at inf on
metric recall (proven). R1 adds the missing structural key.
- RealizedRecord/metadata carry ordered `relation_arguments` (the relation-space
key R0's sorted `entity_names` discards) and a span-free `structure_key`.
- `recall_realized(ctx, subject=/predicate=/content_hash=/structure_key=/
structure_kind=/entity=)` retrieves realized facts by EXACT structural metadata
(no metric / ANN), via a new read-only `VaultStore.iter_metadata()` accessor.
- Idempotency now dedups on the span-free `structure_key`, so the same proposition
told from a different source/offset collapses (R0's span-inclusive content_hash
could not). Guarded by an ambiguous-entity-name refusal — a wrong=0 defense,
since `Entity.name` is non-unique in the model (only `entity_id` is enforced).
- `content_hash` retained for provenance + replay_hash; `vault_index` pinned to the
live deque position.
Design adversarially verified (docs/analysis/REALIZE-R1-DETERMINE-scope-2026-06-06.md);
the false "established pattern" private-access comment is removed in favor of the
public accessor. wrong=0 + versor_condition<1e-6 + exact CGA recall preserved;
vault/store.py adds only a read-only accessor (no normalization). Green: 23 realize
+ 110 invariant/vault + 90 smoke; ruff check clean.
