Ratifies the Mosaic Stack PRD rev1 (Jason Woltje, 2026-09-01) as project
source of truth and installs the GOV.1 lifecycle model:
- docs/PRD.md becomes a permanent shim (kind: shim, current_rev ->
docs/PRDs/2026-08-31_PRD_rev1/). Its path never changes again.
- docs/PRDs/2026-08-26_PRD_rev0/PRD.md archives the 2026-08-26 North Star
verbatim (sha256 60cc2f98...36afdf unchanged). Archive, never delete.
- docs/PRDs/2026-08-31_PRD_rev1/ is the frozen rev1 bundle: 18 sectioned
documents (VIS, DATA, AUTHN, AUTHZ, SEAT, ROLE, HARN, PROV, SESS, UI, CLI,
GOV.1-5) consolidating rev0 D1-D15, the fleet north star, the agent-runtime
L1/L2 contracts and the control-plane-surfaces lane findings, with a single
decision map (GOV.3) and a closed open-questions frontier (GOV.5, grill
rounds 1-8). Drafting inputs (_source-* snapshots) are not shipped.
Consequences of the ratified rulings carried in the same change:
- Q-T1 (ruling B, "shipped but frozen"): D3 amended in GOV.3/VIS.1;
federation M1-M3 acknowledged as shipped behind tier === 'federated',
excluded from the v1 bar and frozen, with a security re-audit gate before
any resumption. docs/MISSION-MANIFEST.md, docs/federation/MISSION-MANIFEST.md
and docs/scratchpads/mvp-20260312.md get status: superseded + banners
(content preserved verbatim); docs/guides/deployment.md gains a
"Relationship to the PRD (D15)" section. NORTH_STAR.yaml adds dormant
workstream M (projects no goals by design); NORTH_STAR.md regenerated.
- Q-G2 (distinct registry prefixes): every citation of the operator
DECISION-REGISTER in the bundle reads OD-nn; the stack registry stays
D1-D15; L1-Dnn/L2-Dnn untouched. Prefix rule recorded in GOV.1.
Follow-ups (not in this PR): CI parity drift-gate witness (Q-C1); brain-side
DECISION-REGISTER rename to OD- with redirect table on its next touch.
