Spec §3 steps 2–5 + §8, TDD-ed offline (scripted, honesty-marked stand-in):
- budget.py: BudgetMeter over TerminationContract — provider-reported usage
only (missing usage fails closed), structured BudgetExceeded stop event.
- loop.py: ModelClient protocol; blind parse-retry generation (never silent
repair); round-capped debate with turn safety net and mandated VERDICT
line; opt-in-reject checker gate (explicit REJECT overrides a validated
outcome, validator rejection stands); most-recent-reason-verbatim informed
refinement under max_attempts; validator_decision stamped BEFORE override,
checker_decision as its own result field (§9, never conflated).
- 45 new tests (121 total, no API key); four detach proofs run RED and
reverted green: checker override, informed block, surfaced checker output,
stamp-before-override.
