P-02 termination-witness — pass  [DEFENSIBLE]
  best-effort             P-01 found the topology ill-formed, so this property's contract does not 
cover it: read this as a diagnostic, not as a verdict
  witness                 0 declared witnesses in the inventory | acyclicity certificate present
    inventory               0 entries
    certificate             present and re-checkable — a topological order of the graph with the 
witnessed elements removed, over 5 vertices: START -> check_availability -> book_flight -> 
send_confirmation -> END

P-03 signature-soundness — not checked  [deferred-to-phase-1]
  status                  no verdict was reached — this is not a pass, and it is outside the Phase-0
wedge
    detail                  P-03 signature-soundness is outside the Phase-0 wedge (SOW §8) and has 
no validator in this release; the catalog contract is PROPERTY-CATALOG-SPEC §P-03 (stub; 
Verification-Properties §2 authoritative). No verdict was reached — this is not a pass.

P-04 dataflow-completeness — pass  [DEFENSIBLE-A]
  best-effort             P-01 found the topology ill-formed, so this property's contract does not 
cover it: read this as a diagnostic, not as a verdict
  witness                 1 (reader, key) obligation covered
    coverage                1 (reader, key) obligation covered
    covered                 send_confirmation reads booking_id <- covered by book_flight

P-05 guard-exhaustiveness — not checked  [deferred-to-phase-1]
  status                  no verdict was reached — this is not a pass, and it is outside the Phase-0
wedge
    detail                  P-05 guard-exhaustiveness is outside the Phase-0 wedge (SOW §8) and has 
no validator in this release; the catalog contract is PROPERTY-CATALOG-SPEC §P-05 (stub; 
Verification-Properties §2 authoritative). No verdict was reached — this is not a pass.

P-06 effect-safety — pass  [DEFENSIBLE-A]
  best-effort             P-01 found the topology ill-formed, so this property's contract does not 
cover it: read this as a diagnostic, not as a verdict
  witness                 0 cycles | 0 effect-tagged nodes recorded
    cycle inventory         0 cycles
    effect                  no node declares a trigger effect tag

P-07 retry-coherence — not checked  [deferred-to-phase-1]
  status                  no verdict was reached — this is not a pass, and it is outside the Phase-0
wedge
    detail                  P-07 retry-coherence is outside the Phase-0 wedge (SOW §8) and has no 
validator in this release; the catalog contract is PROPERTY-CATALOG-SPEC §P-07 (stub; 
Verification-Properties §2 authoritative). No verdict was reached — this is not a pass.

P-08 determinism-replay — pass  [HEURISTIC]
  witness                 0 declared determinism claims
    claim class             heuristic (carried in-band)
    claims                  no node declared determinism, so nothing was checked — this is not a 
statement that every node is deterministic

P-09 parallel-safety — not checked  [deferred-to-phase-1]
  status                  no verdict was reached — this is not a pass, and it is outside the Phase-0

summary
  findings                5 fatal | 0 error | 0 warning

  best-effort             termination-witness, dataflow-completeness, effect-safety — answered on 
topology P-01 found ill-formed, so those reports are diagnostics, not verdicts
  exit                    1 — a FATAL or ERROR finding is present, or a strict policy promoted a 
warning
  snapshot                not recorded for this run: a FATAL finding is present
