C1-DRYRUN-EXECUTION 08 — C1 Rollback / Dismantle & Clean-State Proof — 2026-06-22

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

---

1. What test/sandbox state was created: NONE

No contract registered, no schema created, no value admitted, no authorization consumed, no DOT executed, no dry-run dispatched (files 03/05/06). The entire session was read-only discovery + KB report writes. 0 runtime mutations.

2. Therefore rollback execution is not required — and clean-state is trivially true

Per macro §3.5 "pure-dry-run no-state" branch (here strengthened to no-dry-run, no-state):

• No persistent C1 state exists to dismantle.
• No orphan state, no dangling dependency, no active invalid value, no consumed-auth inconsistency — because nothing was created or consumed.
• Audit retained: the read-only probe trail (file 02) and this package are the audit; no audit row was written to the governed runtime.
• Before == After (file 09): the live counts that define C1 state (c1_table=0, c1_contracts(DOT_C1_*)=0, c1_functions=0, c1_views=0, auth_total=0) are identical at session start and end.

3. Rollback path — design-tested only

The governed rollback model (carried from RS5B/PATCH2): versioned retirement with successor, never DELETE; no orphan/erase/weaken; local; audit-retained; forward-fail-closed. This remains a design/fixture specification — it cannot be exercised live because (a) there is no created state to retire and (b) the compensation handlers do not exist (c1_functions=0). No claim is made that rollback was executed.

4. Classification & boundary attestation

NO_STATE_CREATED ⇒ CLEAN_STATE_TRIVIALLY_PROVEN (0 writes); ROLLBACK_PATH_DESIGN_ONLY. REGISTRATION_HOLD retained; CAN_PROCEED = NO; 0 runtime mutations.
