contract(onboarding-wizard): revision 15 — bootstrap-status envelope split (NEW-20 residual), active-window mutant attribution (NEW-22)

Sol r14 re-review left two findings. NEW-20 residual (BLOCKER): §2.3
closed the bootstrap-status response to epoch/mode with no other field,
conflicting with contract 5 §4.3's mandatory correlation echo on mapped
operations (§§1.1, 7 item 8). Rev 14's state-derived/envelope split is
now applied to bootstrap-status: §2.3 bounds state-derived content only
and carries the contract 5 §4 envelope; §6 item 2's closed-field
assertion and §7 item 2's description follow. Contract 5 not amended.

NEW-22 (MAJOR): the active-window witness claimed its seed-workspace-
scoped mutant fails branches (b) and (c); it passes (c). The witness now
attributes (b) to that mutant, names the separate all-workspace mutant
branch (c) catches, and states branches (a)/(b)/(c) start from isolated
copies of the same incomplete pre-state.

Preamble: Revision 15 paragraph; Revision 14 superseding note.

+# Mosaic Stack Roadmap
+
+Companion to [docs/PRD.md](./PRD.md). Governed by the D11 rule: **every planned
+phase appears here from day one, even as a placeholder** — nothing exists only
+in heads. A phase marked _placeholder_ is a commitment to design it, not a
+design; scoping one requires its own PRD section or requirements doc plus
+review.
+
+Phases are product phases. The in-flight platform workstreams (KBN-100/101
+kanban SOT implementation, FCM #758, FCOM #766, TESS, RI #1275, and the other
+Part II contracts in the PRD) run as parallel tracks under their own issues
+and are prerequisites where noted.

+## P0 — current state
+
+What exists on `next` today: web dashboard (login/register/SSO, chat,
+read-only projects/tasks, settings, admin user/system-health tabs), the
+Gateway, the CLI-first framework tooling, and the fleet control plane. The
+webUI audit (USC estate, webui-audit lane) measures the gap between this and
+P1.
+
+## P1 — v1 slice (D11)
+
+1. Standalone onboarding wizard: system/company name, component choices,
+   initial user, initial estate + project, seeded examples, re-runnable.
+2. Hierarchy core: company → estate → project → workspace → kanban, read-only
+   task bubble-up (kanban SOT Amendment A1 is the schema contract).
+3. Basic RBAC on the hierarchy.
+4. Minimal agent enrollment: one harness, API key, name/persona.
+
+Prerequisites: KBN-100/101 schema foundation; the D8 tool inventory and
+webUI→tool mapping (any missing tool is built first, D12).
+
+## P2 — connectors + comms + wizard expansion (placeholder)
+
+Email and drive connectors (Gmail/IMAP, Google Drive/OneDrive/Dropbox) with
+granular agentic-access consent; comms integrations (Matrix/Discord/Slack)
+including agent auto-enroll. Wizard gains the corresponding tabs (D4), plus
+the D4 capabilities deferred out of P1's minimal slice: expanded agent
+enrollment (OAuth login, multi-account, model choice with recommendation,
+account assignment, comms auto-enroll) and the Standalone SSO/OIDC
+configuration tab.
+
+## P3 — full onboarding profile + M365 (placeholder)
+
+Complete user onboarding profile (communication-style capture, optional
+voice-matching interview) under the D14 custody rule; M365 connectors,
+available to both deployment modes as ordinary connectors (same consent model
+as the P2 connector class). The Enterprise install flow's M365 prominence
+(D4) arrives with the Enterprise phase, P4.
+
+## P4 — Enterprise mode + conversion (placeholder)
+
+Enterprise install flow (org chart, RBAC focus, immediate OIDC, SSO
+prominent); per-user brains with architectural isolation (D14); Vault
+required; the one-way Standalone → Enterprise conversion (D3).
+
+## P5 — federation (placeholder)
+
+Connecting deployments: system-level config, assigned users, rights and
+data-access control, trusts with boundaries, strict data access, exfiltration
+monitoring. Explicitly not designed yet (D3); nothing in earlier phases may
+foreclose it. Requires its own PRD + threat model before any scoping.

 ## 7. Global release evidence
 
 P0–P3 may close only when requirements traceability maps every requirement above to automated and situational evidence, including cross-workspace denials, DB/Valkey fault injection, concurrent leases, stale fencing, generated-file immutability, UI conflict/reconnect behavior, migration reconciliation, independent review, mandatory SecReview, and final Certifier evidence.
+
+## 8. Amendment A1 — hierarchy parentage and RBAC chain above workspaces
+
+**Status:** amendment to the ratified canon, added by reviewed PR under
+decision D13 (operator ruling, 2026-08-25; decision owner Jason). It adds
+parent structure ABOVE workspaces. Sections 1–7, every invariant in §3, and
+every REQ above remain binding verbatim, with exactly one express modification:
+the narrow portfolio-analytics carve-out stated in §8.2.4. Nothing else below
+this line is weakened.
+
+### 8.1 What is added
+
+1. A platform hierarchy exists above workspaces:
+   **company/organization → estate → platform-project → workspace**. Each
+   workspace belongs to exactly one platform-project, each platform-project to
+   exactly one estate, each estate to exactly one company.
+2. **Record class.** Hierarchy records (company, estate, platform-project,
+   their parentage edges, and hierarchy-level access grants) are a new,
+   explicitly named record class: **tenancy/authorization structure records**.
+   They are not business or orchestration records, so §3 invariant 10 and
+   REQ-TEN-001 do not apply to them and are not weakened by them — those two
+   requirements bind business/orchestration rows exactly as before.
+   Constraints on the new class:
+   - Hierarchy tables MUST NOT carry task, plan, or any other
+     business/orchestration payload — parentage, naming, and grant data only.
+   - A hierarchy record can never be the subject of work: it cannot be
+     claimed, ordered, gated, or referenced as a dependency by any
+     business/orchestration row.
+   - Hierarchy mutations flow through the same sole-writable-SOT, fail-closed,
+     audited mutation path as everything else (§8.2.3).
+3. The hierarchy serves exactly two runtime functions, plus audited
+   maintenance of its own structure:
+   - **RBAC evaluation:** access grants are declared per company, estate, or
+     platform-project and evaluate down the chain to workspace-scoped
+     authorization. Tenant context continues to be derived from authenticated
+     authority (REQ-TEN-001); the chain adds where grants can be declared,
+     not a bypass of workspace authorization.
+   - **Read-only roll-ups:** task and status visualization bubbles up the
+     hierarchy as aggregation over workspaces the reader is authorized on.
+   - **Chain maintenance (not a third runtime function):** re-parenting an
+     asset — moving a workspace to another platform-project, a
+     platform-project to another estate, and so on ("assets are transferable
+     subject to the structure", PRD Part I §4) — is an audited edit of the
+     hierarchy records themselves under §8.3. It never modifies
+     business/orchestration rows and never crosses a workspace boundary for
+     them; the workspace's contents move with the workspace untouched.
+4. Naming: this amendment says **platform-project** for the hierarchy level
+   above workspaces, because §5 REQ-PLAN-001 already defines `projects` as
+   planning entities INSIDE a workspace. The two are different objects. Final
+   terminology (rename of one or the other) is an implementation-PR decision
+   under this amendment's review; the schema MUST NOT merge them.
+
+### 8.2 What is explicitly unchanged
+
+1. `workspace_id` remains the hard mechanical isolation unit (§2 D2,
+   REQ-TEN-001). Hierarchy tables carry parentage; they do not create
+   cross-workspace relationships between business/orchestration rows, which
+   remain rejected (§3 invariant 10).
+2. Roll-up is **never a write**: no aggregation path may mutate, claim, order,
+   or gate work in any workspace. Bubble-up views are generated projections in
+   the sense of §3 invariant 5 — non-authoritative and never import sources.
+3. Fail-closed mutation health (§3 invariants 3–4), sole writable PostgreSQL
+   SOT, fencing, audit, and the Coordinator/Certifier authority rules are
+   untouched.
+4. No §6 non-goal is authorized, with one express, narrow carve-out that this
+   amendment makes to the "portfolio analytics" non-goal: the read-only
+   roll-up of §8.1 — per-workspace task counts and statuses aggregated up the
+   parent chain, over workspaces the reader is authorized on — is in scope.
+   Everything beyond that boundary (metrics, trends, forecasting, scoring,
+   dashboards computed across workspaces, any derived analytic that is not a
+   direct count/status aggregation) remains a non-goal. This is an explicit
+   narrowing by amendment, not a claim that §6 is unchanged; every other §6
+   non-goal is untouched.
+
+### 8.3 Acceptance (binding on the implementing PRs)
+
+- Schema tests prove each workspace resolves to exactly one
+  platform-project/estate/company chain and that chain edits are audited.
+- Authorization tests prove a grant at each hierarchy level yields exactly the
+  workspace permissions the chain implies, and that revocation up the chain
+  propagates.
+- Negative tests prove roll-up endpoints cannot mutate state and that a
+  reader sees aggregates only over workspaces they are authorized on
+  (no cross-tenant existence oracles).
