06 — No-Execute / Plan-Only Test (Workstream E)

All tests run live against the committed dispatcher.

Fail-closed battery (each in its own transaction)

#	Call	Result
T1	PLAN_ONLY, write=false, DOT_KG_EXPLAIN	validated=true, endpoint_present=false, true_dry_run_possible=false, blocker=agent_api_endpoint_missing, observation_written=false
T2	DRY_RUN, no endpoint	REFUSED: "DRY_RUN requires a real no-mutation endpoint; endpoint_ref is NULL"
T3	unknown dot_code	REFUSED: "no agent_api contract for DOT_DOES_NOT_EXIST"
T4	empty correlation_id	REFUSED: "missing correlation_id"
T5	REAL_RUN	REFUSED: "REAL_RUN not permitted by this dispatcher"

Prepared-observation write test (idempotency + invariants)

• W1 producer PLAN_ONLY write=true → run 87989341-….
• W2 verifier VERIFY_ONLY write=true → run d1be9e40-….
• W3 idempotent re-call of W1 → same UUID 87989341-…, 0 new rows.

Post-state proven:

• births_before == births_after == 1,163,392 (birth-free).
• Dispatcher-sourced obs (agent_api_dispatch_planonly): 2 runs + 2 components, all SIMULATED_DRY_RUN.
• Pilot usage_count / last_executed — still NULL (DOT never executed).
• process_run_observation evidence_type tally: SIMULATED_DRY_RUN=4, DRY_RUN=0, REAL_RUN=0.
• event_outbox rows for these correlations: 0.

Status

No-execute / plan-only path proven end-to-end. The dispatcher validates the contract, prepares a correlated observation, is idempotent, and cannot cross into DRY_RUN/REAL_RUN/verified.
