Phase 1 of the post-ADR-0024 sequence: wire the inner-loop flag into live
cognition paths and prove deterministic-when-wired in the same milestone.
Changes:
- RuntimeConfig: add inner_loop_admissibility + admissibility_threshold.
- ChatRuntime: pass both into generate() on the chat hot path.
- CLI: --inner-loop-admissibility / --admissibility-threshold flags.
- vocab/manifold.py: document strict `>` tie-break as load-bearing for
ADR-0024 rejected_attempts ordering (determinism by construction, not
by accident).
- tests/test_inner_loop_admissibility.py: three new determinism tests —
identical rejected_attempts across 5 runs, identical trace hash across
5 runs (non-empty), and legacy hash equivalence when no rejections
occur (flag on/off byte-identical).
- tests/test_language_pack_cache.py: fix stale fixture (en-core-cog-070
-> en-core-cog-085 after pack growth).
Suite: 995 passed, 0 failed, 2 skipped.
Acceptance criteria met:
- wired through RuntimeConfig + CLI + ChatRuntime + generate()
- deterministic rejected_attempts sequence (verified by repetition)
- deterministic trace hash under inner_loop=True
- legacy ADR-0023 trace hashes preserved when no rejections
- nearest_next determinism is by construction (sequenced iteration +
strict > tie-break), now documented
Next: Phase 2 — corpus-observation eval on existing v1 corpus with the
four-condition matrix (boundary-only, null control, inner-loop t=0.0,
inner-loop t>0) and exhaustion_rate + latency metrics.
Flag-gated semantic change to generate(): when
inner_loop_admissibility=True and a non-unconstrained region is
supplied, each per-step selection is re-evaluated by check_transition
with admissibility_threshold; rejected candidates are excluded and
the walk re-selects until admitted or every admissible candidate is
exhausted (ValueError = honest refusal, same shape as ADR-0022 §2).
Default False — every legacy call site keeps ADR-0023 boundary-only
semantics, and the new AdmissibilityTraceStep.rejected_attempts field
is folded into canonical() only when non-empty, so trace_hash bytes
are byte-identical with ADR-0023 turns.
Invariants preserved: rotor V is only built for the admitted
candidate, so versor_condition < 1e-6 still holds at propagate_step;
no new normalization site; no new I/O / dynamic imports.
Tests: tests/test_inner_loop_admissibility.py covers the four
acceptance properties — default off preserves behavior, rejection
drives re-selection, exhaustion raises ValueError, empty
rejected_attempts is omitted from canonical(). Full pytest: 927
passed, 1 pre-existing unrelated failure (test_language_pack_cache).
