-Pytest-based integration testing using real external dependencies (PostgreSQL, git repos), FastAPI TestClient with authenticated fixtures, mocked database fixtures for isolation, and security validation patterns (cookie/ OIDC/ SSE auth).
+Pytest-based integration testing with FastAPI TestClient, SQLAlchemy async sessions, real PostgreSQL database fixtures, and selective mocking; follows pattern of endpoint-per-test-file with authenticated client fixtures and seeded database state.

+# Handoff: Tool Container Home Directory
+
+## Session context
+
+- Original request: make tool container workspace/home directory default to `/home/user`, keep it user-writable, and preserve repo root directory name in the mount target.
+- Completed a Grill Me session that resolved design decisions.
+- Phase 1 implementation was started but blocked by persistent Grill Me read-only guard.
+
+## Current branch
+
+- `feat/tool-container-home-directory` (created from `dev`)
+
+## Committed artifacts on `dev`
+
+- `docs: tool container home directory design, plan, and test plan`
+- `chore: update project maps for tool container home directory artifacts`
+
+## Files already created/edited on `feat/tool-container-home-directory`
+
+- `apps/api/src/models/tool/tool_type.py`
+  - Added `home_directory: Mapped[str]` column, default `"/home/user"`.
+- `apps/api/alembic/versions/2026_06_14_104415_add_tool_type_home_directory.py`
+  - Adds column, sets existing rows to `/home/user`.
+  - Rewrites `/workspace` to `/home/user/{{WORKSPACE_NAME}}` in `compose_template` and `dockerfile_template`.
+  - Provides reversible downgrade.
+
+## Design decisions resolved
+
+| Area | Decision |
+|------|----------|
+| Config surface | `home_directory` field on ToolType / manifest schema |
+| Default | `/home/user` |
+| Runtime user | Still `manifest.user.name` |
+| Mount target | `{home_directory}/{repo_name}` or `{home_directory}/{workspace_name}` |
+| Precedence | Explicit manifest repo mount target wins; `home_directory` fills in default |
+| Migration | Alembic data migration for legacy ToolType templates |
+| Compatibility | `/workspace` symlink to actual repo/workspace target |
+| Permissions | Entrypoint permission fixer at container startup |
+| Tests | Unit + integration tests |
+
+## Pending work
+
+### Phase 1 verification
+Run in `apps/api`:
+```bash
+python -m alembic current
+python -m alembic upgrade head
+python -m alembic downgrade -1
+python -m alembic upgrade head
+```
+
+### Phase 2: Manifest compiler
+File: `apps/api/src/services/build/manifest_compiler.py`
+- Honor `manifest.home_directory` in `get_manifest_home_dir()`.
+- Set `ENV HOME={home_directory}`, `ENV USER={user.name}`, `WORKDIR {home_directory}`.
+- Create `/workspace` symlink step.
+- Use `{home_directory}/{repo_name}` as default repo mount target when no explicit repo mount exists.
+
+### Phase 3: Legacy instance generation
+File: `apps/api/src/services/tool/instance_service.py`
+- Use `tool_type.home_directory` for `dockerfile` tool mounts.
+- Add `WORKSPACE_NAME`/`HOME_DIRECTORY` template variables for compose tools.
+
+### Phase 4: Config-profile / git mount expansion
+Files: `apps/api/src/services/tool/instance_service.py`, `apps/api/src/services/config/config_profile_resolver.py`
+- Thread resolved `home_dir` through startup.
+
+### Phase 5: Entrypoint permission fixer
+Files: `apps/api/src/services/build/manifest_compiler.py`, `apps/api/src/services/shared/permission_fixer.py`, `tool-images/base.dockerfile`
+- Generate startup script that chowns `{home_directory}` and key mounts to container user.
+
+### Phase 6: Tests
+Create/expand:
+- `apps/api/tests/unit/test_home_path_expansion.py`
+- `apps/api/tests/unit/test_manifest_compiler.py`
+- `apps/api/tests/unit/test_instance_service.py`
+- `apps/api/tests/unit/test_alembic_migrations.py`
+- `apps/api/tests/integration/test_tool_instance_lifecycle.py`
+
+## Reference docs
+
+- `openspec/designs/tool-container-home-directory.md`
+- `docs/superpowers/plans/tool-container-home-directory.md`
+- `docs/superpowers/specs/tool-container-home-directory-test-plan.md`
+- `openspec/tasks/home-path-expansion.md`
+
+## Next action for fresh session
+
+1. Ensure you are on `feat/tool-container-home-directory`.
+2. Verify Phase 1 migration round-trip.
+3. Continue with Phase 2 (manifest compiler).
