-# Session Protocol
+## Session Protocol
 
-1. Read `INTENT.md`, the PRD, the FRS, and active workplans.
-2. Check State Hub for dispatch and blockers when available.
-3. Treat workplan files as authoritative coordination state.
-4. Record durable decisions in repository docs before reflecting them in State Hub.
-5. Keep the implementation boundary narrow: syntax-layer toolkit, not platform.
+State Hub: http://127.0.0.1:8000
+
+**Step 1 — Orient**
+
+Read the offline-safe brief first — it works without a live hub connection:
+```bash
+cat .custodian-brief.md
+```
+Then call the MCP tool for richer cross-domain context when MCP tools are exposed:
+```
+get_domain_summary("markitect")
+```
+If MCP tools are unavailable in the current agent session, use the REST API:
+```bash
+curl -s "http://127.0.0.1:8000/state/summary" | python3 -m json.tool
+```
+If the hub is offline: `cd ~/state-hub && make api`
+
+**Step 2 — Check inbox**
+With MCP tools:
+```
+get_messages(to_agent="markitect-tool", unread_only=True)
+```
+Mark read with `mark_message_read(message_id)`. Reply or act on coordination
+requests before proceeding.
+
+Without MCP tools:
+```bash
+curl -s "http://127.0.0.1:8000/messages/?to_agent=markitect-tool&unread_only=true" \
+  | python3 -m json.tool
+curl -s -X PATCH "http://127.0.0.1:8000/messages/<id>/read" \
+  -H "Content-Type: application/json" -d '{}'
+```
+
+**Step 3 — Scan workplans**
+```bash
+ls workplans/
+```
+For each file with `status: ready`, `active`, or `blocked`, note pending
+`todo`/`in_progress` tasks.
+
+**Step 4 — Present brief**
+
+1. **Active workstreams** for `markitect` — title, task counts, blocking decisions
+2. **Pending tasks** from `workplans/` + any `[repo:markitect-tool]` hub tasks
+3. **Goal guidance** — if `goal_guidance` in summary:
+   - `needs_workplan`: surface as top action — *"Repo goal '{title}' has no workplan yet"*
+   - `alignment_warnings`: flag if active work is not aligned with current goal
+4. **Suggested next action** — highest-priority open item
+5. **SBOM status** — flag if `last_sbom_at` is unset for this repo
+
+If no workstreams: follow First Session Protocol (`first-session.md`).
+
+**During work:** `record_decision()` · `add_progress_event()` · `resolve_decision()`
+
+> State Hub is a *read model*. Bootstrap tools (`create_workstream`, `create_task`)
+> are First Session Protocol only. Work structure belongs in repo files (ADR-001).
+
+**Session close:**
+With MCP tools:
+```
+add_progress_event(summary="...", topic_id="5571d954-0d30-4950-980d-7bcaaad8e3e2", workstream_id="<uuid>")
+```
+Without MCP tools:
+```bash
+curl -s -X POST http://127.0.0.1:8000/progress/ \
+  -H "Content-Type: application/json" \
+  -d '{"topic_id":"5571d954-0d30-4950-980d-7bcaaad8e3e2","workstream_id":"<uuid>","event_type":"note","summary":"what changed","author":"codex"}'
+```
+If workplan files were modified, ensure the local copy is up to date first:
+```bash
+git -C <repo_path> pull --ff-only
+cd ~/state-hub && make fix-consistency REPO=markitect-tool
+```
+For repos where implementation runs on a remote machine (e.g. CoulombCore),
+use the combined target which pulls before fixing:
+```bash
+cd ~/state-hub && make fix-consistency-remote REPO=markitect-tool
+```
+**C-15** (DB task ahead of file) is normal in multi-machine workflows — writeback
+will sync the file to match DB.  **C-16** (repo behind remote) blocks all writes
+until you pull — intentional to prevent clobbering remote progress.
