+## First Session Protocol
+
+Triggered when `get_domain_summary("consumer")` shows **no workstreams**.
+The project is registered but work has not yet been structured.
+
+**Step 1 — Read, don't write**
+- `~/the-custodian/canon/projects/consumer/project_charter_v0.1.md` — purpose, scope
+- `~/the-custodian/canon/projects/consumer/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 workstreams to Bernd**
+Propose 1–3 workstreams — each a coherent strand, weeks to months, anchored to a
+roadmap phase. **Wait for approval before creating.**
+
+**Step 4 — Create workplan file first, then DB record (ADR-001)**
+```
+workplans/HUMAN-WP-NNNN-<slug>.md   ← write this first
+```
+Then register in the hub:
+```
+create_workstream(topic_id="4c2e5315-2cb9-447c-9d16-a39bdb0aabd0", title="...", owner="...", description="...")
+create_task(workstream_id="<id>", title="...", priority="high|medium|low")
+```
+
+**Step 5 — Record the setup**
+```
+add_progress_event(
+    summary="First session: structured consumer into N workstreams, M tasks",
+    event_type="milestone",
+    topic_id="4c2e5315-2cb9-447c-9d16-a39bdb0aabd0",
+    detail={"workstreams": [...], "tasks_created": M}
+)
+```
