+
+Do not mint a stranded `wait` when another repo/owner is the blocker.
+
+1. Look for a `prj-` workplan that lists both repos (`spec/coordination-model-v0.2.md`). That plan is the **driver**; product repos **implement**.
+2. Observe the foreign record on State Hub. Do not copy or PATCH the other owner's tasks.

+5. Do not message `ops-warden` for secrets (SSH certs only).

+## 1. Document Status
+
+**Document:** coordination-model-v0.2.md
+**Project:** coordination-engine
+**Version:** 0.2
+**Status:** Addendum to v0.1 (COORDINATION-WP-0005)
+**Scope:** Project-repository workplans as coordination drivers
+**Extends:** `spec/coordination-model-v0.1.md`
+**Related:** `spec/cross-owner-wait-mode-v0.1.md`,
+`spec/worker-coordination-service-v0.1.md`,
+`the-custodian/canon/architecture/adr-005-cross-repo-workplans-project-repos.md`,
+`the-custodian/canon/standards/project-repository-flavor_v0.1.md`
+
+v0.1 remains the ontology. This addendum maps **estate work records** onto
+that ontology. It does not replace actors, goals, commitments, or observation
+loops.
+
+## 2. Purpose
+
+Cross-repository work in this estate is supposed to live in a **project
+repository** (`prj-<slug>`, `repo_flavor: project`, ADR-005). Agents were
+instead minting stranded `wait` notes on product workplans. The engine must
+treat a `prj-` workplan as the **driver** of a `CoordinationCase`, and
+product-repo workplans as **implementers**.
+
+## 3. Out of scope
+
+- The engine **does not author workplans**. Files remain source of truth
+  (ADR-001). State Hub remains the work-record read model.
+- The engine **does not replace State Hub**, Fabric, or product
+  implementation in participating repos.
+- The engine **does not vend credentials**. `ops-warden` issues SSH
+  certificates only.
+- This addendum **does not enable live worker injection**. Wake/lease
+  remains the v0.1 worker-coordination service, off until an operator
+  starts it.
+
+## 4. Driver and implementer
+
+| Role | Binding | Authority |
+| --- | --- | --- |
+| **Driver** | Workplan whose repo is `prj-*` / `category: project` / `repo_flavor: project` | Sequences the effort, names participating repos, holds `depends_on` and related child ids. Does not implement production code. |
+| **Implementer** | Workplan in a participating product/tooling repo | Owns code, tests, deployables, and local tasks. |
+
+Participant roles on the case (v0.1 `Participant.roles[]`):
+
+- `driver` — the project-repository actor (system: State Hub record +
+  project repo)
+- `implementer` — each participating product repo (system)
+- `observer` — State Hub / Fabric (read-only)
+- `agent` — a worker only when the v0.1 service has selected that gita
+  repo as a wake target
+
+A workplan with `flavor: residual` is **not** a driver and is **not**
+actionable demand unless promoted (STATE-WP-0092). Unspecified flavor is
+relevant.
+
+## 5. Mapping onto v0.1
+
+```text
+prj- workplan  →  CoordinationCase
+  goal         ←  GOAL.md outcome + workplan title
+  driver       ←  the prj- workplan (commitment: sequence the effort)
+  implementers ←  child workplans in other repos (related / depends_on)
+  commitments  ←  depends_on edges (kind: response | completion)
+  observations ←  State Hub task/workplan status, receipts
+```
+
+`depends_on` is a **commitment**, not prose. The obligor is the
+implementer (or upstream driver) named by the target id. The beneficiary
+is the waiting plan. Satisfaction is the target reaching a terminal
+satisfactory status (`done` / `finished` / `archived`), matching the
+v0.1 worker-coordination dependency rule.
+
+`related:` without `depends_on` is context, not a commitment.
+
+## 6. Case identity
+
+```yaml
+CoordinationCase:
+  id: "case:prj:{repo_slug}:{workplan_id}"   # derived, not authored
+  scenario_type: project_driver
+  driver_workplan_id: string                 # hub UUID or canonical id
+  driver_repo: prj-*
+  implementers:
+    - repo: string
+      workplan_id: string?
+      role: implementer
+  commitments:                               # from depends_on
+    - kind: completion
+      obligor_workplan_id: string
+      beneficiary_workplan_id: string
+  flavor: planning | implementation | ...    # driver's flavor
+```
+
+The engine derives this object from hub JSON. It does not POST a
+workplan.
+
+## 7. Worked example — `prj-helixforge-factory` / `HFACT-WP-0001`
+
+Repo `prj-helixforge-factory` is `repo_flavor: project`. Workplan
+`HFACT-WP-0001` (“Establish the internal HelixForge software factory on
+Railiance”) is the driver. It states that it owns integration acceptance
+and handoff and **neither replaces nor copies child implementation
+plans**.
+
+Implementers named in `related:` include `GLAS-WP-0012`, `SAND-WP-0015`,
+`REINAH-WP-0003`, `ACTIVITY-WP-0032`, `KEY-WP-0013`, `INFD-WP-0001`,
+`APPROVAL-WP-0002`, `SECRETS-WP-0009`, `AUDIT-WP-0009`, `RPF-WP-0038`.
+Those remain implementer workplans in their owning repos.
+
+A wait on `KEY-WP-0013` from the factory driver is a **commitment** on
+the key-cape implementer, not a stranded `wait` on the driver with no
+observer. Cross-owner handling is `spec/cross-owner-wait-mode-v0.1.md`.
+
+## 8. Compatibility
+
+v0.1 cases that are not `scenario_type: project_driver` are unchanged.
+The worker-coordination service continues to poll ready/active
+implementer tasks. This addendum tells it (and agents) which workplan is
+the driver when one exists.

+# Cross-owner wait handling mode v0.1
+
+Status: specified (COORDINATION-WP-0005-T02). Not a live wake enablement.
+Owner: coordination-engine.
+Reconciles with: `spec/worker-coordination-service-v0.1.md` (do not fork
+leases, safety, TAMQ, or receipts).
+Ontology: `spec/coordination-model-v0.2.md`.
+
+## Problem
+
+Repo A sets a task `wait` because repo B’s owner has not returned. Nobody
+observes B. The wait becomes a stranded inbox. That pattern is the top
+theme holding the open-workplan count up.
+
+## Mode (replace “set wait and hope”)
+
+### Entry
+
+Any of:
+
+1. A task is `wait` / `needs_human` and names another repo, owner, or
+   workplan id.
+2. A workplan is `blocked` on a `depends_on` target whose `repo` is not
+   this repo.
+3. A `prj-` driver lists both repos (preferred). If no driver exists,
+   still open a **case object** from the waiting plan — do not author a
+   new workplan.
+
+Do **not** enter this mode for `flavor: residual` unless the flavor has
+been promoted.
+
+### Observe
+
+Read the foreign owner’s record from State Hub (workplan, tasks,
+`depends_on`, flavor, repo classification). Do not copy their task list
+into this repo. Do not PATCH their tasks.
+
+### Attach
+
+Open or attach a `CoordinationCase` (`scenario_type: project_driver`
+when a `prj-` workplan exists, otherwise `scenario_type: cross_owner_wait`).
+The waiting plan is the beneficiary. The foreign plan is the obligor
+commitment.
+
+### Act (only if the v0.1 service is already running)
+
+Lease/wakeup **only** selected gita-registered worker targets for the
+implementer that is actually unblocked. Safety, sensitive-text stops,
+human flags, and “no silent reroute” are exactly the v0.1 worker service.
+This mode does not add a second wakeup path.
+
+If the service is not running, the case still exists as a derived object
+and a hub-projectable receipt of `observed` / `waiting`. Agents follow
+the instruction pack instead of injecting workers.
+
+### Checkpoint
+
+Reuse v0.1 checkpoint shape (summary, files_changed, next_action,
+blocked_reason, 8 KiB, local). `blocked_reason` stops automatic
+continuation. A checkpoint is not completion.
+
+### Fail closed
+
+Missing authorization, unregistered target, residual-as-driver, or
+attempt to reassign another owner’s task → `stopped` with reason. Never
+silently re-assign.
+
+### Exit
+
+| Exit | Condition |
+| --- | --- |
+| `satisfied` | Obligor workplan/task reaches `done`/`finished`/`archived` |
+| `stopped` | Safety, human, missing auth, residual driver |
+| `waiting` | Foreign record still open; case remains attached |
+
+## Receipt shape (hub-projectable)
+
+Extends the v0.1 sanitized receipt (state, reason, lease/trigger ids).
+Additional fields (no payloads, no secrets):
+
+```yaml
+scenario_type: project_driver | cross_owner_wait
+case_id: string
+driver_workplan_id: string?
+driver_repo: string?
+obligor_workplan_id: string
+beneficiary_workplan_id: string
+flavor: string?
+```
+
+Projection remains `POST /progress/` with
+`event_type: coordination_receipt` as in the v0.1 Hub adapter. Queued
+edge-relay receipts are not proof of central publication.
+
+## Common estate pattern
+
+Repo A (e.g. `net-kingdom`) blocked on repo B (e.g. `key-cape`,
+`flex-auth`, OpenBao owner). If `HFACT-WP-0001` (or another `prj-`
+driver) already lists both, attach there. Otherwise derive
+`cross_owner_wait` from A’s waiting workplan. Observe B. Do not implement
+B’s tasks from A’s session. Do not message `ops-warden` for a secret.
+
+## Anti-patterns
+
+- Stranded `wait` with no case and no observer
+- Copying B’s tasks into A’s workplan
+- Treating `flavor: residual` as a driver
+- Inventing `warden secret` / asking ops-warden for API keys
+- Enabling live worker injection as a side effect of documenting this mode
