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.

Step 1 of the loop, built from method-spec §3 alone:
- okf.py (pure stdlib): frontmatter parse, deterministic/tolerant/boundary-checked
index navigation, bundle_context rendering with type:verdict exclusion
- experience.py: CandidateFeatures from the IR projection, §4.2 id minting,
structural ranking (0.60·Jaccard + 0.25·type + 0.15·magnitude bucket),
first-write-wins store, bundle seeding with the realization marker,
fold-before-generation (empty retrieval → base unchanged)
Load-bearing (§11), each proved RED on detach: verdict-layer exclusion, fold,
seed learning fields, agent-toolkit import guard. 76/76 without an API key;
ruff + mypy --strict clean.

TDD from method-spec alone (§3 Step 4, §7, §9), golden.json as the only
ground truth: ir.py (construction invariants, fail-fast bundle loader),
validator.py (closed-form feasibility bound 0.30·Σ + Monte Carlo seed
20260624/512 samples/inclusive quantiles — reproduces every frozen golden
field; Rejection as a distinct unconsumable type), provenance.py (stamp
mirroring ONLY the deterministic validator). Mutation controls + seed-detach
proof (§11); 45/45 green without an API key; ruff + mypy --strict clean.

Claude Agent SDK verified against official docs + PyPI 2026-07-03 (0.2.110, CLI
bundled, offline import without API key). Contracts mirror method-spec §10/§4.1/§8:
data-source, model-map (per-profile default required), termination (positive caps),
binary feedback decision. TDD: tests written red-first; suite 14/14 green without
any API key; ruff + mypy --strict clean.
