CLOSE the autonomous-loop spine: when idle, the engine consolidates each
soundly-derived determination back into the held self, so the next determine()
reaches it directly and can chain one hop further. The directly-answerable set
climbs monotonically across idle ticks to the deductive-closure fixed point.
Mechanism — generate/determine/consolidate.py::consolidate_once runs ONE
semi-naive layer of the member/subset deductive closure (member∘subset → member,
subset∘subset → subset; NEVER member∘member — instance-of is not transitive).
Each one-hop conclusion not yet realized is VERIFIED by the sound+complete
proof_chain ROBDD (reusing C's single verifier _verify_subsumption) and written
back via generate/realize::realize_derived as a SPECULATIVE realized record
carrying derived-provenance (premise structure_keys + rule + the ENTAILED
verdict). idle_tick gains a consolidation pass gated by the new
config.consolidate_determinations (default OFF); IdleTickResult.facts_consolidated
reports the layer.
Invariants held:
- wrong=0 — every consolidated fact is a sound-rule conclusion confirmed by the
sound+complete decider; member∘member is structurally unreachable (a member fact
is only ever extended by a subset edge). _verify_subsumption now refuses a
mislabeled/wrong-arity path (belt-and-suspenders now that consolidation is a
second caller), so the fallacy cannot be laundered through a corrupted chain.
- honesty — a fact derived from SPECULATIVE premises stays SPECULATIVE / as-told;
the soundness of the inference never upgrades the standing of the premises.
COHERENT is never minted.
- teaching-safety — SESSION memory (immediate), an extension of the realize path;
NOT corpus mutation and NOT coupled to proposals. The HITL path is untouched.
- determinism/replay — pure function of the realized set; sorted write order;
derived structure_key identical to a told fact's; provenance round-trips through
the Shape B+ snapshot (consolidated facts resume the SAME life across reboot).
- no new normalization — writes reuse the INV-21-allowed vault writer;
algebra/versor.py keeps closure.
Falsification — evals/determination_closure: a frozen replay seeds a deep is-a
chain and runs idle ticks; asserts the closure climbs monotonically to a complete
fixed point (no-op final tick), wrong=0 (member∘member canary never derived, no
fabricated membership), all derived facts SPECULATIVE, and every derived record
re-verifies ENTAILED from its recorded premises.
Verified green: smoke, runtime, cognition, architectural invariants, plus the new
D unit + lane tests and the determine/realize/persistence regression net. Five-lens
adversarial review: 4 lenses held; the 5th (normalization) was a misattribution
(pre-existing vault reproject, triggered identically by the merged realize path,
on sanctioned null-vector storage). Design + findings: docs/analysis/
