 ## First Session Protocol
 
-Triggered when State Hub shows no workstreams for `core-hub`.
+Triggered when `get_domain_summary("infotech")` shows **no workplans**.
+The project is registered but work has not yet been structured.
 
-**Step 1 - Read, do not write yet**
-- `INTENT.md`
-- `SCOPE.md`
-- `docs/research/2026-06-27-core-hub-lineage-and-platform-reset.md`
-- `docs/specs/README.md`
-- Existing files under `workplans/`
+**Step 1 — Read, don't write**
+- `~/the-custodian/canon/projects/infotech/project_charter_v0.1.md` — purpose, scope
+- `~/the-custodian/canon/projects/infotech/roadmap_v0.1.md` — planned phases
+- Scan repo root: README, directory structure, existing code or docs
 
-**Step 2 - Survey in-progress work**
-Look for untracked files, open workplans, and half-finished specs. Note done vs. started but incomplete.
+**Step 2 — Survey in-progress work**
+Look for TODOs, open branches, half-finished files. Note done vs. started but incomplete.
 
-**Step 3 - Structure work in files first**
-Create or update `workplans/CORE-WP-NNNN-<slug>.md` before relying on State Hub records.
-
-**Step 4 - Sync the read model**
-After workplan changes, run from `~/state-hub`:
+**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/CORE-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
-make fix-consistency REPO=core-hub
+statehub fix-consistency --repo core-hub
+```
+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 infotech into N workplans, M tasks",
+    event_type="milestone",
+    topic_id="cee7bedf-2b48-46ef-8601-006474f2ad7a",
+    detail={"workplans": [...], "tasks_created": M}
+)
 ```
 
-**Step 5 - Record progress**
-Post a non-secret progress note to State Hub summarizing the setup or implementation work.
+<!-- Delete or archive this file once past first session -->
