Macro-3 Staging Next-Branch Readiness Map (2026-06-19)

Date: 2026-06-19 · Workstream: R2-B2-MACRO-3-OPTION-D-OWNER-DELEGATE-DECISION-PACKAGE-2026-06-19 (Deliverable 34 of 60) · Editorial revision: rev1 Class: staging readiness map · READ-ONLY · NON-ENACTING · NON-AUTHORIZING · staging-schema-corpus-drift-guard · NO staging created · NO write performed.

Metadata convention. Editorial revision (rev1) only. Storage revision/content_length authoritative at read time.

Staging lock. This maps what a future staging branch would need; it creates no staging schema or corpus. Creating either is STAGING_SCHEMA_OR_CORPUS_DRIFT → HOLD.

---

0. Status and non-authorization

STATUS: PASS — engineering / decision-prep. Maps staging readiness for Macro-4; builds nothing. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Show what staging readiness depends on, so Macro-4 can be scoped — without opening staging now.

2. Sources / evidence read

Macro-2 staging-after-owner-decision readiness map, staging-build not-opened register. Main process, no reader-agents.

3. Accepted baseline (carried)

Staging is opened only after the three Owner decisions; it is build-readiness IO-only, with a promotion firewall to prod.

4. Evidence / analysis — dependency map

Staging input	Depends on	Status
chosen channel	CH-Q1 (D15)	undecided
assigned owner model	S2-Q1 (D23)	undecided
source-authority path	0G-Q1 (D31)	undecided
staging schema/corpus	all three above + Owner	not opened

5. Recommendation / matrix / result

Staging readiness is blocked on the three decisions. Macro-4 prepares the readiness (SR-style obligations, no-prod-touch, delete-fast, promotion firewall) only after they are made. No staging artifact created here.

6. Owner-gated future work

Building any staging schema/corpus is Owner-gated; forbidden now.

7. What remains unresolved

All three inputs undecided; staging not opened.

8. Ready for GPT/Codex review

Yes — Codex should confirm no staging schema/corpus is created or specified concretely here.
