0. Status and non-authorization

STATUS: PASS — engineering / design-only. The evidence conceptual object: append-only, records-never-decides, STAGING-tagged. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Describe what a run records so it is observable and reproducible.

2. Sources / evidence read

Macro-4 B2 evidence contract (D32); evidence model (18); operating-rules AP-CLOSE. Main process, no reader-agents.

3. Accepted baseline (carried)

Evidence is append-only and downstream; it never acts as approval; B2 must not read it to decide.

4. Evidence / analysis — evidence candidate

Aspect	Description (no schema)
role	the observable, reproducible record of a run
field family	counts, run-identity (incl. channel id), per-failure, reproducibility-hash
tag	STAGING (never read into a production decision)
never	a certify/approval; a production S7 write

5. Candidate / requirement / gate / result

The evidence object makes a run auditable without granting authority. It is a role, not a table; nothing is recorded here. Approvals remain only in S1/Điều 32.

6. Owner-gated future work

Building the evidence object/sink is Owner-gated; forbidden now.

7. What remains unresolved

The concrete sink is FUTURE_TECHNICAL_DESIGN_REQUIRED.

8. Ready for GPT/Codex review

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