Hygiene: SCOPE stance sentence, stack/architecture stubs, first-session archive

Record the published fail-closed PEP stance in SCOPE, fill the agent
stack and architecture stubs from the shipped layout, and retire the
first-session protocol now that USER-WP-0001–0024 exist.

+## First Session Protocol
+
+**Retired 2026-08-29.** Work is structured (USER-WP-0001–0024). Kept as
+history; do not run. Active session flow is `session-protocol.md`.
+
+Triggered when `get_domain_summary("communication")` shows **no workplans**.
+The project is registered but work has not yet been structured.
+
+**Step 1 — Read, don't write**
+- `~/the-custodian/canon/projects/communication/project_charter_v0.1.md` — purpose, scope
+- `~/the-custodian/canon/projects/communication/roadmap_v0.1.md` — planned phases
+- Scan repo root: README, directory structure, existing code or docs
+
+**Step 2 — Survey in-progress work**
+Look for TODOs, open branches, half-finished files. Note done vs. started but incomplete.
+
+**Step 3 — Propose workplans to Bernd**
+Propose 1–3 workplans — each a coherent strand, weeks to months, anchored to a
+roadmap phase. **Wait for approval before creating.**
+
+**Step 4 — Write the workplan file; fix-consistency registers it (ADR-001)**
+```
+workplans/USER-WP-NNNN-<slug>.md   ← write this, commit it
+```
+Then register by running the consistency check — do **not** call
+`create_workplan`/`create_task` yourself; manual registration duplicates what
+C-06 creates from the file:
+```bash
+statehub fix-consistency --repo user-engine
+```
+C-06 creates the hub workplan + tasks and writes `state_hub_workstream_id`
+(legacy frontmatter name — holds the workplan UUID) and `state_hub_task_id`
+back into the file.
+
+**Step 5 — Record the setup**
+```
+add_progress_event(
+    summary="First session: structured communication into N workplans, M tasks",
+    event_type="milestone",
+    topic_id="a6c6e745-bf54-4465-9340-1534a2be493e",
+    detail={"workplans": [...], "tasks_created": M}
+)
+```
+
+<!-- Delete or archive this file once past first session -->
