0. Status and non-authorization

STATUS: PASS — engineering / design-only. Refines the Macro-4 B2 input contract for the staging-build context — no scope widening. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Carry Macro-4's B2 input contract (D29) forward, adding only the workbench-input clarifications a build would need.

2. Sources / evidence read

Macro-4 B2 input contract (D29); input candidate (24); Điều 0-G §2.4. Main process, no reader-agents.

3. Accepted baseline (carried)

B2 reads uncertified/governed rows + Điều 0-G rule-set + B3 contract; never B4 internals/channel/KG/canonical/identity/certified-precondition.

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

Clarification	For the workbench build
input is a disposable projection	the build seeds a copy, never reads live rows as authority
shape is frozen (F-1)	the projection mirrors the FRESH shape (inspect_*/certified/metadata)
scope narrowed	uncertified + PEN governed only
fail-closed	malformed projection row → reject, never fabricate

5. Candidate / requirement / gate / result

The refinement adds no new read surface — it only clarifies the workbench reads a copy. No widening; no binding to live rows. G-2 (runtime B3/B4 re-confirm) remains Partial.

6. Owner-gated future work

Binding input to a built workbench is Owner-gated; forbidden now.

7. What remains unresolved

observed-role scope remains BAD_INPUT_BEHAVIOR_UNCLEAR.

8. Ready for GPT/Codex review

Yes — Codex should confirm the refinement adds no new dependency and no live-row read.
