0. Status and non-authorization

STATUS: PASS — engineering / design-only. Refines the Macro-4 B2 output contract; output stays candidate-only. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Carry the candidate-only output forward, clarifying the build writes only to the disposable surface.

2. Sources / evidence read

Macro-4 B2 output contract (D30); output candidate (25); Điều 0-G §2.4 (ordered, per-column). Main process, no reader-agents.

3. Accepted baseline (carried)

B2 writes candidate inspect_pen/stamp/gate only — genuine per-stage, one column per inspector, ordered, idempotent; never production/certify/canonical.

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

Clarification	For the workbench build
target	the disposable surface only (never production birth_registry)
order	PEN→STAMP→GATE enforced; out-of-order → reject (BI-11)
idempotent	re-running a stage yields the same candidate, no double-write
STAMP/GATE	least-precedented; logic stays design-open

5. Candidate / requirement / gate / result

The refinement re-affirms candidate-only and never widens to production inspect_*/certify/canonical (firewall, 32). No candidate is written here.

6. Owner-gated future work

Writing real production inspect_* (in a built governed producer) is Owner-gated; forbidden now.

7. What remains unresolved

STAMP/GATE logic remains the least-precedented part.

8. Ready for GPT/Codex review

Yes — Codex should confirm output stays candidate-only and ordered.
