0. Status and non-authorization

STATUS: PASS — engineering / design-only. The master plan for proving (later) that the workbench never touched production. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Answer macro question 5 — what no-production-touch proof is required? — as a single master plan.

2. Sources / evidence read

Workbench no-production-touch requirements (11); pilot-slice staging IO contract §11; bad-input/delete-fast plan §10; Macro-3 no-production-touch risk map. Main process, no reader-agents.

3. Accepted baseline (carried)

The proof is a before/after comparison of production counts/checksums plus the staging evidence (CAV-3/CAV-4: read-only tooling proves state via snapshots/catalog reads).

4. Evidence / analysis — proof plan structure

Part	Deliverable	Proves
Before/after snapshot	44	production counts/checksums identical
Forbidden surfaces	45	the exact surfaces that must be unchanged
Runtime proof obligations	46	what a runtime check must show
Source proof obligations	47	no source/law/report patched
Promotion firewall	48	no staging→production flow

5. Contract / requirement / matrix / result

This macro itself honored no-production-touch: only read-only query_pg/list_docker + KB doc creation (Deliverable 81 ledger). For a future B2 run, the plan is the required shape of proof; no such proof is run here.

6. Owner-gated future work

Running the proof against a built workbench is Owner-gated; forbidden now.

7. What remains unresolved

The concrete snapshot harness is FUTURE_TECHNICAL_DESIGN_REQUIRED.

8. Ready for GPT/Codex review

Yes — Codex should confirm the plan covers runtime + source + promotion proof.
