"""Vault V2 smoke — create-seam, janitor sweep, KB-ingest cycle.

Cross-layer wiring for the vault V2 subsystems, driven for real against the
e2e stack's ephemeral Postgres and a per-test tmp_path vault:

- Create seam: the REAL ``TaskService.create`` (real DB row, real
  ``assemble_task_note_data`` + ``VaultWriter``) materializes the task note
  on create; flag off writes nothing. Nothing vault-side is mocked.
- Janitor sweep: real seeded task rows, the REAL ``VaultJanitor.run_cycle``
  (real TaskService queries, real reproject/archive paths, real state file).
  ``vault_report_enabled`` is off so the sweep scenario stays focused on
  drift repair + archival (the weekly report is unit-covered).
- KB ingest: real notes on disk, the REAL ``VaultKBEngine.run_cycle`` +
  REAL injection guard (scan, containment, frontmatter split, screening,
  content-hash dedup, quarantine callout all real). The ONLY stub is the
  Optimal seam (``get_optimal_service`` returns a stateful in-memory
  registry standing in for ``index_vault_note`` / ``unindex_vault_note`` /
  ``list_indexed_documents``) — the real OptimalService needs the Ollama
  embedder + vector store, which the e2e stack deliberately has no egress
  to; the registry preserves the tracking-row semantics the engine's dedup
  reads back.

Each scenario passes in isolation (per-test table truncation + per-test
tmp vault).
