REALIZE roadmap Step 3, slice R0: the boundary that turns comprehension from an
EVAL ARTIFACT into accumulating living knowledge. A comprehended declarative fact is
integrated into the held self as a structured vault entry (versor, metadata) — NOT a
new store — so it inherits exact cga_inner recall, EpistemicStatus stamping, and
bit-exact Shape B+ persistence for free. Scope: docs/analysis/REALIZE-scope-2026-06-06.md.
generate/realize/realize.py — realize_comprehension(Comprehension|Refusal, ctx) ->
Realized(record, created) | NotRealized(reason):
- eligibility: a Comprehension (not Refusal) with NO queries and EXACTLY ONE
non-negated relation whose subject grounds IN-VOCABULARY. Everything else is a
typed NotRealized with zero vault writes (wrong=0).
- in-vocab-subject only: OOV grounding is non-deterministic across reboots (an
empirically-confirmed substrate gap), so OOV subjects are declined in R0.
- SPECULATIVE always (COHERENT is never a default — ADR-0021); provenance via
MeaningSpan source_span + structure_canonical; content_hash + replay_hash via
canonical-JSON SHA-256 (floats forbidden).
- idempotency: dedup by content_hash within the session (exact-canonical,
span-inclusive — safe direction only, never drops a distinct fact).
- durable schema admits a 2nd substrate later via structure_kind/structure_canonical.
- stores via the existing VaultStore.store path: no new embedder, no normalization
(closure stays algebra/versor.py), no parallel learning path.
Explicitly OUT of R0: COHERENT promotion, teaching-loop proposals, trace-folding,
relation-space recall, the arithmetic/binding_graph path.
tests/test_realize_r0.py (10) — eligibility (refusal/query/multi-relation/OOV all
write nothing); record fields; idempotency (re-told fact doesn't grow the vault);
SPECULATIVE status firewall (recall(min_status=COHERENT) excludes it); the
falsifiable exit gate (told -> realize -> snapshot -> reboot -> recall: byte-exact
content_hash + score + versor bytes, speculative, versor_condition<1e-6); and
replay_hash re-derivable after reboot. Gate verified to BITE (COHERENT default,
refusal-writes, reprojection-on-load all fail it).
INV-21: generate/realize/realize.py added to ALLOWED_VAULT_WRITERS — a sanctioned
writer (same VaultStore.store path, SPECULATIVE default, nothing on Refusal).
Adversarially reviewed (3 lenses: invariants/wrong0/honesty, determinism/boundary,
scope/adjustments) — no critical/high/medium findings; low/nit honesty wrinkles
folded (state-dependent-placement wording, span-inclusive-dedup note, direct
versor-bytes gate assert, replay_hash re-derivation test). 10 R0 + 90 smoke green;
lane SHAs 8/9 (sole miss = public_demo env flake; deductive_logic + math_teaching
unchanged -> no GSM8K coupling).
