A served response carries two ORTHOGONAL governance properties: ReachLevel (how
far past grounded fact it reaches) and DisclosureClaim (the epistemic claim it
makes about its own truth status). "verified" is NOT a reach level — it is a
proof-state claim. Keeping the axes separate is the locked Stage-2 decision (no
ReachLevel.VERIFIED; a proven answer never inherits an [approximate] surface).
core/epistemic_disclosure/disclosure_claim.py:
- DisclosureClaim(str, Enum): none | verified | approximate | proposal_only.
Default = none. str-valued for stable serialization (EpistemicState convention).
- Discipline "no claim without a producer": every member has a real (APPROXIMATE
= cognition Step E; PROPOSAL_ONLY = teaching/proposals) or imminent (VERIFIED =
Phase 1 target) emitter. PROVEN and ESTIMATED are intentionally ABSENT — nothing
emits them; ESTIMATED is a future split of APPROXIMATE, added only when a real
estimator producer exists (docs-note only).
Also folds the P0-1 review nit: _KIND_TO_STATE / _ACTION_TO_TERMINAL tightened
from dict[str, ...] to their Literal key types.
9 tests, non-vacuous: default is NONE; verified is not a ReachLevel (structural);
claim axis disjoint from ResolutionAction; PROVEN and ESTIMATED absent; exactly the
approved four; str-enum serialization; module imports nothing (off-serving).
No bus behaviour, no ServedDisposition mapping (that is P0-3). Off-serving; smoke
green (90 passed) locally.
