+## Extraction Boundary Inventory
+
+Inventory captured on 2026-05-17 against
+`/home/worsch/the-custodian/state-hub` and target stub
+`/home/worsch/state-hub`.
+
+### Move To `state-hub`
+
+These paths are tracked service source or service-owned operations assets and
+should become authoritative in `/home/worsch/state-hub`:
+
+| Path | Handling |
+|------|----------|
+| `.dockerignore` | Move; revisit because current Docker context excludes `tests`, `docs`, and `infra`. |
+| `.env.example` | Move; remains the safe config template. |
+| `Dockerfile` | Move; update build context references after extraction. |
+| `Makefile` | Move; becomes the primary State Hub command surface. |
+| `README.md` | Move/merge with standalone repo baseline README. |
+| `alembic.ini` | Move. |
+| `api/` | Move; FastAPI app, models, schemas, routers, event publisher. |
+| `custodian_cli.py` | Move; update any repo-root assumptions. |
+| `dashboard/observablehq.config.js` | Move. |
+| `dashboard/package.json` | Move. |
+| `dashboard/package-lock.json` | Move. |
+| `dashboard/src/` | Move; dashboard source and data loaders. |
+| `docs/` | Move; State Hub operational and architecture docs. |
+| `flows/` | Move; task-flow definitions. |
+| `infra/` | Move; local Postgres compose and infra docs. |
+| `mcp_server/` | Move; MCP server and tool reference. |
+| `migrations/` | Move; Alembic migration environment and versions. |
+| `policies/` | Move; repo DoI and workstream DoD policies. |
+| `prompts/` | Move; State Hub prompt assets. |
+| `pyproject.toml` | Move; Python package/dependency definition. |
+| `scripts/` | Move; consistency, registration, SBOM, token, image, and repo-sync tooling. |
+| `task_flow_engine/` | Move; embedded flow evaluator package. |
+| `tests/` | Move; keep in repo even though Docker image currently excludes it. |
+| `uv.lock` | Move; required for reproducible `uv sync`. |
+
+### Keep In `the-custodian`
+
+These remain Custodian-owned after extraction:
+
+| Path | Handling |
+|------|----------|
+| `canon/`, `memory/`, `runtime/`, root `workplans/` | Stay in `the-custodian`; not part of State Hub service source. |
+| Root `AGENTS.md`, `CLAUDE.md`, `.custodian-brief.md`, `SCOPE.md` | Stay, but update to point State Hub code work at `/home/worsch/state-hub`. |
+| `workplans/CUST-WP-0043-state-hub-repo-extraction.md` | Stay as the bridge plan until extraction is complete. |
+| `workplans/CUST-WP-0042-workplan-state-model-cleanup.md` | Re-home or bridge after standalone repo registration; do not duplicate blindly. |
+| `state-hub/` | Remove or replace with a small pointer only after standalone verification passes. |
+
+### Regenerate Locally
+
+These paths are useful locally but should not be copied as source:
+
+| Path | Handling |
+|------|----------|
+| `.venv/` | Regenerate with `make install` / `uv sync`. |
+| `dashboard/node_modules/` | Regenerate with the dashboard package manager install. |
+| `dashboard/dist/` | Regenerate via Observable build/preview. |
+| `dashboard/src/.observablehq/` | Regenerate as Observable cache. |
+| `.pytest_cache/` | Regenerate from test runs. |
+| `**/__pycache__/`, `*.pyc` | Regenerate from Python execution. |
+
+### Discard / Do Not Copy
+
+These are local, sensitive, or machine-specific:
+
+| Path | Handling |
+|------|----------|
+| `.env` | Do not copy; secrets/local config stay local. |
+| `.claude/settings.local.json` | Do not copy; machine/user-local Claude settings. |
+| `kubectl` | Do not copy unless later proven to be a tracked intentional helper; currently ignored and machine-local. |
+
+### Target Stub State
+
+`/home/worsch/state-hub` currently contains only `.git/`, `.gitignore`,
+`LICENSE`, and a repo-seed README. It needs a service-specific baseline before
+the implementation move:
+
+- README that identifies State Hub as the live FastAPI/MCP/dashboard service.
+- `AGENTS.md` with the State Hub session protocol.
+- `SCOPE.md` for repo discovery and capability registration.
+- A `workplans/` directory or explicit decision about the repo-local workplan
+  prefix before re-homing `CUST-WP-0042`.
+- A tightened `.gitignore` that keeps `uv.lock`, docs, infra, and tests
+  trackable while excluding runtime/build/cache/secrets.
+
