Wires comprehend->realize/determine into the live turn loop: a declarative turn
REALIZES a fact into the held self (session vault, SPECULATIVE/as-told); a question
turn is DETERMINED over realized knowledge (answered as-told, or refused open-world).
The first time a CORE conversation actually accumulates knowledge it can recall and
reason over — the 'one continuous life' telos made real, including across reboot
(the accrued fact is in the Shape B+ snapshot, so it survives the process ending).
Seam: all chat() returns funnel through _checkpointed_response; accrual runs there
BEFORE the checkpoint (so the fact persists this turn), gated by a new
accrue_realized_knowledge flag (default OFF — one-shot/eval runtimes don't accrue;
the production L10 process enables it with persist_session_state).
Discipline: SESSION memory, not ratified learning — proposes nothing, HITL untouched.
Realization writes go through generate.realize (INV-21 allowed writer). Additive: a
failure is a clean no-op, never crashes a turn. Slice B-1 RECORDS the outcome
(last_turn_accrual(), introspectable) and leaves the ChatResponse/surface contract
UNCHANGED; surfacing the determination is the B-2 follow-up (needs runtime_contracts
+ contract-test updates).
Tests: declarative accrues; question determines as_told; untold refuses open-world;
idempotent retell not recreated; flag-off no-ops with identical surface; and the
lived-spine proof — accrued knowledge survives reboot (determined as_told after a
fresh runtime over the same checkpoint).
