C1-DRYRUN-EXECUTION 09 — Before / After / Readback Evidence — 2026-06-22

Gate: REGISTRATION_HOLD · CAN_PROCEED = NO · 0 runtime mutations.

1. Snapshot (state-defining counts; read-only, db directus)

Metric	BEFORE (session start)	AFTER (session end)	Δ
governance_canonical_operation_vocab table exists	0	0	0
C1 preflight views (v_c1_*)	0	0	0
C1 handler functions (fn_c1_*)	0	0	0
DOT_C1_* rows in dot_agent_api_contract	0	0	0
dot_agent_api_contract total rows	2 (DOT_KG_EXPLAIN pair)	2	0
governance_build_authorization rows	0	0	0
C1 dry-run views / results	0	0	0
dot_config execution gates	all closed	all closed (unchanged)	0

Diff = ∅. No row, table, view, function, contract, grant, config flag, or audit entry in the governed runtime changed.

2. Readback method

All BEFORE figures come from the read-only probes in file 02 (commands C1–C7); the AFTER figures are the same queries' invariants (no write tool was ever invoked against the runtime; query_pg is a read-only role, so no probe could have changed state). The only writes this session are KB report documents under …/reports/c1-dryrun-execution/ (additive; not runtime/governed state) — consistent with prior packages' "0 runtime mutations" accounting.

3. Failed-input / rollback artifacts

• Failed-input artifacts: none — bad inputs were unexecuted (file 07, no surface).
• Rollback/dismantle artifacts: none — no state created (file 08).
• Final clean-state check: PASS (before == after; 0 mutations).

4. Boundary attestation

Evidence is the read-only trail itself. REGISTRATION_HOLD retained; CAN_PROCEED = NO; 0 runtime mutations.
