0. Status and non-authorization

STATUS: PASS — engineering / design-only. Refines the Macro-4 B2 evidence contract; records-not-decides preserved. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Carry the append-only evidence contract forward, emphasising STAGING tagging for the workbench.

2. Sources / evidence read

Macro-4 B2 evidence contract (D32); evidence candidate (27); FRESH event_outbox=215,611. Main process, no reader-agents.

3. Accepted baseline (carried)

Evidence is append-only and downstream; never an approval; B4 owns certified; approvals live in S1/Điều 32.

4. Evidence / analysis — refinement (build-context only)

Clarification	For the workbench build
tag	every workbench evidence row tagged STAGING (never production S7)
channel id	recorded for auditability
reproducibility	AP-CLOSE paths/hashes
FRESH	production S7 writers stay future-gated (event_outbox 215,611 undrained, no birth events)

5. Candidate / requirement / gate / result

The refinement keeps evidence downstream and STAGING-tagged; no production S7 write. No evidence is emitted here.

6. Owner-gated future work

Building the evidence writers is Owner-gated; forbidden now.

7. What remains unresolved

The concrete sink is future TD; S7 remains PARTIAL.

8. Ready for GPT/Codex review

Yes — Codex should confirm evidence records-not-decides and is STAGING-tagged.
