feat(vault): Obsidian vault V2 — janitor, archival, weekly report, KB ingest, Bases + sync runbook (#482)

* feat(vault): V2 — create-seam + drift janitor, archival, weekly org-report, KB ingest, Bases views + sync runbook Implements the vault V2 canonical spec end to end (the splice guard shipped separately and is reused at KB-ingest time): - materialize-on-create: TaskService.create writes each task's note best-effort from the moment it exists; the transition-touch stops no-oping on live work - drift janitor (services/vault_janitor.py + hourly _vault_janitor_loop): daily changed-task re-projection, random drift sample, archival pass — restart-proof via RoboCo/_meta/.janitor_state.json, 200/cycle caps, per-item isolation, processed-only resume markers, self-repairing state file - archival: vault_archive_days (30, 0=off) moves old terminal tasks' notes to RoboCo/Archive/<year>/Tasks/<project>/ — one write_task code path for janitor and rebuild, id8 lookup across Tasks/+Archive/, alias links keep moves safe - weekly org-report: VaultWriter.write_org_report renders Reports/<ISO-week>.md from MetricsService/UsageService (numbers duplicated into frontmatter for trend queries), once per ISO week, with a best-effort CEO notification - KB ingest: IndexType.VAULT_NOTES + VaultNotesIndexPlugin + _vault_kb_loop embed the CEO's RoboCo/Notes into the RAG corpus — injection guard as a hard gate (flagged notes quarantined with an idempotent callout), traversal- and symlink-contained at both config and engine layers, content-hash dedup, 50-ingest/cycle cap, frontmatter stripped; reaches roboco_kb_search, the mentor default domain, claim-time briefings (kind vault_note), and the panel KB browser; no migration (chunks table auto-creates; migration 030's CHUNK_TABLES tuple appended per the chunks_playbooks precedent) - Bases views (Task Board.base, Reports.base — schema verified against the Obsidian docs) + the Mac sync runbook vault asset - config/flags/compose: vault_archive_days, vault_report_enabled (flags card), vault_kb_enabled (flags card; NAS compose arms it, registry ships it off), vault_kb_dirs (+ overlap/traversal validator), vault_kb_interval_seconds - e2e smoke (tests/e2e_smoke/test_vault_v2.py): real create-seam, real janitor cycle incl. archival + state, real KB engine + real guard * docs: vault V2 sweep — map, RAG corpus, CLAUDE.md - docs/map/vault.md: V1+V2 — janitor/archival/report/KB data flows, new files, config, health posture - docs/map/orchestrator.md + task-service.md: the two new loops, the create seam, the three janitor queries - docs/rag/architecture/obsidian-vault.md: agent-facing what-changed (notes from creation, archive link-safety, CEO notes retrievable, weekly report) - docs/rag/architecture/config-reference.md: the five new settings - CLAUDE.md: vault paragraph covers V1+V2; flags-card list mentions the vault report/KB flags --------- Co-authored-by: Renn F <rennf93@users.noreply.github.com>

 **Board roadmap engine (default-off).** The Board originating strategic work: on a weekly interval (`ROBOCO_ROADMAP_ENGINE_ENABLED` + `_INTERVAL_SECONDS` / `_MIN_ITEMS_PER_CYCLE` / `_MAX_ITEMS_PER_CYCLE`) `RoadmapEngine` (`roboco/services/roadmap_engine.py`) opens ONE held **exploration** task (`source="board_roadmap"`, `confirmed_by_human=False`, PENDING, Product-Owner-assigned, `Team.BOARD`), deduped to one open cycle at a time. A dedicated one-shot `_dispatch_roadmap_exploration` spawns the Product Owner **solo** — deliberately NOT `_handle_board_assigned_task` (which would also spawn Head of Marketing and fire the Approve-&-Start handoff, both wrong for a PO-authored cycle) — reusing the `_board_dispatched` one-shot tracker + respawn breaker, and short-circuiting once the cycle is authored. The PO explores (read-only git, KB/RAG, metrics, releases, charter, optional web research) and makes ONE `propose_roadmap` call (a content verb gated to `product_owner` only, `_ROADMAP_ROLES`; wired through the do_server/Choreographer like `pitch`) authoring a **themed cycle** — a one-line goal + 3-7 item drafts — persisted as a `roadmap_cycle` marker on the exploration task (no table/migration). The CEO acts per-item in the panel roadmap queue (`roadmap-review-queue.tsx`; `/api/roadmap/cycles{,/items/{id}/approve,/items/{id}/reject}`, CEO-only): approve materializes that item as a BACKLOG task (`source="roadmap"`, no assignee — never auto-starts; normal PM activation picks it up) via `PrompterService.create_task_from_draft`, reject records a reason; when every item is terminal the exploration task completes (`RoadmapService`, idempotent per item). Dispatchers skip `board_roadmap` (never delivery work). `create_task_from_draft` honors a draft-declared `source` only from a `{prompter, roadmap}` whitelist — an LLM-authored draft can't impersonate a privileged origin.

-**Obsidian vault V1 (default-off).** The org's human-readable memory palace as a rebuildable DB projection — tasks, journals, and A2A digests as wikilinked markdown — gated by `ROBOCO_OBSIDIAN_VAULT_ENABLED` + `ROBOCO_VAULT_PATH` (default off, but both compose files arm it `true`). `VaultWriter` (`roboco/services/vault_writer.py`) is a pure, DB-free materializer under `RoboCo/{Tasks/<project-slug>,Journals/<agent-slug>,A2A,Agents}/`; every note carries a stable `aliases: [<id8>]` so a title rename never breaks a `[[id8|title]]` cross-link, and private journals are excluded. Three best-effort event seams (`TaskService`'s status-transition frontmatter touch, `JournalService`, `A2AService`) patch/append on the relevant transition — a vault write failure never blocks the real action. `python -m roboco.vault rebuild` re-projects every entity from the DB (preserving an existing task's Auditor-authored `## Narrative`) and materializes the shipped `.obsidian/` config (Dataview, Kanban, graph groups) + `RoboCo/_meta/` dashboards from `roboco/vault_assets/`; `relocate <path>` moves the tree, grafting `RoboCo/` into an existing personal vault without touching its own config. The Auditor gets a one-shot `curate_vault(task_id, narrative)` do-tool, spawned by the orchestrator on each completed root task, writing the `## Narrative` section a deterministic write otherwise leaves as a placeholder. A second, independently-gated `ROBOCO_VAULT_INTAKE_ENABLED` watcher (`VaultIntakeEngine`) turns `#roboco`-tagged notes under the vault's inbox folder into PENDING, Product-Owner-assigned board-review drafts (`source=vault_note`) — the identical board-review path a chat-confirmed draft takes, never straight into delivery. Extraction runs on the local model with a deterministic fallback; the note body is screened through `foundation/policy/injection_guard.screen_external_text` (the same untrusted-content envelope `XEngine` applies to X mentions — flags an injection-pattern line inline, never removes content) before it reaches the prompt or the fallback. Deduped per `(vault-relative path, content hash)` via `vault_seen_notes`, so an edit re-qualifies a previously-seen note.

Deduped per `(vault-relative path, content hash)` via `vault_seen_notes`, so an edit re-qualifies a previously-seen note — the same hashing convention (every RoboCo feedback callout stripped first, `foundation/policy/vault_notes.py`) is now shared with the KB engine below. V2 adds three things on top: a **drift janitor** (`services/vault_janitor.py`, `_vault_janitor_loop`) hourly-ticked but gated by a `RoboCo/_meta/.janitor_state.json` state file so real work (a daily changed-task re-projection + random-sample drift check + archival pass, each capped at 200/cycle and per-item isolated so one bad row never wedges the sweep) and a weekly org-report (`vault_report_enabled`, default true — `VaultWriter.write_org_report` from `MetricsService`/`UsageService`, best-effort CEO notification) each fire exactly once per elapsed period regardless of loop/restart cadence; **archival** (`vault_archive_days`, default 30, `0`=off) moving old terminal tasks' notes into `RoboCo/Archive/<year>/Tasks/<project>/` during the sweep, alias links making the move free and the shipped Dataview/graph assets `Archive/`-aware; and **KB ingest** (`vault_kb_enabled`, default false — NAS compose arms it `true`, registry compose leaves it `false`) embedding the CEO's own `RoboCo/Notes/` (config `vault_kb_dirs`, csv, load-time-validated against traversal/overlap with reserved projection dirs) into a new `IndexType.VAULT_NOTES` corpus via `_vault_kb_loop` (`services/vault_kb_engine.py`, default 900s), with every note re-checked for symlink/path-escape at read time and screened through the injection guard as a hard GATE (a flagged note is quarantined — skipped, logged, callout-marked, never embedded) rather than the intake watcher's screen-and-still-process posture — reaching `roboco_kb_search`, `MentorService`'s default domain, and `EvidenceRepo.similar_memory` (claim-time briefings, relevance-floored, labeled `vault_note`) so the CEO's own writing finally becomes fleet-retrievable institutional memory.

 **Fable-mode (default-off).** Full opus-fable-playbook adoption: makes the fleet behave more like Fable 5 on the existing model tiers (the tiers stay — Fable 5 the model is not an option). Two levers, both gated by `ROBOCO_FABLE_MODE_ENABLED`: ① **doctrine** — `fable_doctrine_layer()` (`roboco/agents/factories/_base.py`) composes the vendored behavioral doctrine (`agents/prompts/doctrine/fable.md`, from `github.com/rennf93/opus-fable-playbook` MIT `output-styles/fable.md`, YAML frontmatter stripped) into `compose_prompt`'s layer tuple immediately after `base.md` — universal cross-role doctrine, the same tier as the base rules, ahead of role/team/identity layers so those keep their specificity precedence. ② **hooks** — 5 vendored scripts under `docker/scripts/fable-*.sh` (stop-gate, bash-discipline, honesty-nudge, prompt-nudge, precompact; `session-start.sh` deliberately SKIPPED — its doctrine card is redundant with ① and its output-style check is inapplicable here) are installed alongside RoboCo's own hooks, never replacing them: `AgentOrchestrator._fable_hook_groups()` appends them AFTER RoboCo's own per-event entries in the Claude-path settings.json (isolated into its own helper to protect `_generate_agent_settings`'s xenon budget); the grok path installs only `honesty-nudge` (`write_grok_fable_hooks`, `roboco/llm/providers/grok_cli_config.py`) — a deliberately conservative V1 scope, since a grok `PreToolUse`/`Stop` hook deny cancels the entire run (verified live) while `PostToolUse` never denies. Off by default: the spawn path (composed prompt, settings.json, grok hooks) is byte-for-byte unchanged when the flag is off. No new eval harness — measurement rides the existing rework/spawn-waste/`revision_count` dashboard (see "Delivery observability" below). Armed on the NAS deploy like the rest; left OFF in `docker-compose.registry.yml`.

 **Ponytail (bundled with Fable-mode).** Rides `ROBOCO_FABLE_MODE_ENABLED` — no separate flag. Vendors the ponytail "lazy senior dev" build-laziness doctrine (`agents/prompts/doctrine/ponytail.md` + ethos sibling, MIT, Copyright (c) 2026 DietrichGebert — trimmed, YAML frontmatter stripped) into every composed system prompt via `ponytail_doctrine_layer` (`roboco/agents/factories/_base.py`), slotted immediately after the Fable doctrine layer and gated on the same flag. Role-scoped: developers (`AgentRole.DEVELOPER`) get the full ladder (YAGNI → reuse-in-this-codebase → stdlib → native-platform → installed-dep → one-line → minimal); every other role gets the ethos-only cut (`ponytail-ethos.md`) — the code-mechanics rungs are dropped so they can't leak into prose artifacts (task plans, review notes, docs). Both files carry a 5-point RoboCo preamble (the ethos sibling adds a 6th: free-text field obligations) that makes the ladder yield to the Architectural Conventions Standard (placement), the 80% coverage gate + QA review + self-verification, the per-team design bar, task hygiene (everything-is-a-task / commits-linked / state-is-sacred), and reviewer feedback (`needs_revision` / `pr_fail` / `request_changes`) — the overlap mitigation is scoping, not deletion, and it rides ponytail's own "when NOT to be lazy" clause. Developer intensity is tunable via `ROBOCO_PONYTAIL_INTENSITY` (`lite` / `full` / `ultra`, default `full`; `roboco/config.py` `ponytail_intensity`, a string value — not a feature flag): `full` enforces the ladder, `lite` builds what's asked and names the lazier alternative, `ultra` is YAGNI-extremist (deletion before addition, challenge the requirement). Non-developers get no dial — `ultra` is wrong for prose artifacts, so the ethos runs a fixed restrained stance. Prompt-only: no hooks, no grok-path changes — ponytail adds no hook surface, so bundling it under the Fable flag changes only the composed prompt, not the spawn hooks. The Fable flag's description in `roboco/config.py` names both doctrines.

 - No flag — `_pending_claim_blocked` (the dependency/sequence claim-gate prefilter) is unconditional, mirroring `TaskService.claim`'s own always-on sequence gate; it is a pure dispatch-time optimization (fails open on lookup error) with no behavior change vs. attempting and failing the claim.

 ## Purpose

-The Obsidian vault V1: a rebuildable, human-readable DB projection of the org's memory (tasks, journal entries, A2A thread digests) as wikilinked markdown, plus a default-off inbox watcher that turns `#roboco`-tagged vault notes into board-review intake drafts. Default-off (`ROBOCO_OBSIDIAN_VAULT_ENABLED`; both compose files arm it `true`). Mirrors the other default-off engines' shape in one respect (event-driven, best-effort, never a gate) but is structurally different: it never originates delivery work itself — the projection is read-only from the DB's perspective, and the ONE writer-side effect that reaches delivery (the intake watcher) rides the existing board-review path, not a held-artifact queue.
+The Obsidian vault (V1+V2): a rebuildable, human-readable DB projection of the org's memory (tasks, journal entries, A2A thread digests) as wikilinked markdown, plus a default-off inbox watcher that turns `#roboco`-tagged vault notes into board-review intake drafts. V2 adds three things on top of the V1 projection: materialize-on-create (a task's note exists from the moment it's created, not just at curation/rebuild), a drift janitor (hourly-ticked, daily/weekly-gated: re-projects changed tasks, verifies a random sample, archives old terminal tasks, writes the weekly org-report), and KB ingest (the CEO's own `RoboCo/Notes/` notes become one more RAG corpus the fleet can retrieve). Default-off (`ROBOCO_OBSIDIAN_VAULT_ENABLED`; both compose files arm it `true`). Still structurally different from the other default-off engines: the projection never originates delivery work itself — the ONE writer-side effect that reaches delivery (the intake watcher) rides the existing board-review path, not a held-artifact queue.

 ## Files

 | Path | Role | approx LOC |
 |---|---|---|
-| `roboco/services/vault_writer.py` | `VaultWriter` — pure, DB-free markdown materializer. `write_task` / `write_journal_entry` / `append_a2a_message` / `write_agent` / `touch_task_frontmatter`. Every note carries `aliases: [<id8>]` so a rename never breaks a `[[id8\|title]]` wikilink; `existing_narrative` reads back an Auditor-authored `## Narrative` section so a rebuild never clobbers it. | 371 |
-| `roboco/services/vault_assembly.py` | `assemble_task_note_data` — resolves a task's project slug, parent, subtasks, and dependencies via the live `TaskService`/`ProjectService` into a `TaskNoteData` for `VaultWriter.write_task`. Shared by `curate_vault` and the CLI rebuild; kept separate from `vault_writer` so that module stays DB-free and trivially unit-testable. | 87 |
-| `roboco/services/vault_intake_engine.py` | `VaultIntakeEngine.run_cycle` — scans the vault's inbox dir for `#roboco`-tagged notes, dedupes via `vault_seen_notes` (path + content-hash), screens the body through `injection_guard.screen_external_text`, extracts a title/description/action-items via a local-model chat call (deterministic fallback: first heading / raw body / checkbox lines), and opens ONE PENDING board-review draft (`source=vault_note`, Product-Owner-assigned, `team=board`) per note. Appends a feedback callout back into the note (best-effort). | 373 |
-| `roboco/vault.py` | `python -m roboco.vault {rebuild,relocate}` CLI. `rebuild` re-projects every agent/task/journal-entry/A2A-thread from the DB and materializes `.obsidian/` + `RoboCo/_meta/` from `roboco/vault_assets/` (never overwrites an existing file). `relocate <path>` moves the tree; grafts `RoboCo/` into an existing destination vault without touching its own config. | 237 |
-| `roboco/vault_assets/` | Packaged templates copied by `ensure_vault_assets`: `.obsidian/` (Dataview, Kanban, graph-group config) + `meta/` (dashboard + kanban-board + README shipped into `RoboCo/_meta/`). | — |
-| `roboco/foundation/policy/injection_guard.py` | `screen_external_text` / `detect_injection` — the shared prompt-injection screen-and-neutralize (data path) and hard-deny (interactive-input path) pattern set, used by both the vault intake watcher and `XEngine`'s mentions poll. | 125 |
+| `roboco/services/vault_writer.py` | `VaultWriter` — pure, DB-free markdown materializer. `write_task` / `write_journal_entry` / `append_a2a_message` / `write_agent` / `touch_task_frontmatter` / `write_org_report`. Every note carries `aliases: [<id8>]` so a rename never breaks a `[[id8\|title]]` wikilink; `existing_narrative` reads back an Auditor-authored `## Narrative` section so a rebuild never clobbers it. V2: `write_task` is archive-aware (`TaskNoteData.archive_year` routes it to `RoboCo/Archive/<year>/Tasks/<project>/` instead of `Tasks/<project>/`, removing the stale copy on a move); `find_task_note`/`task_note_status` locate/inspect a note wherever it lives (recursive id8 lookup across both trees) for the janitor's drift check; `write_org_report` renders `RoboCo/Reports/<ISO-week>.md`. | 534 |
+| `roboco/services/vault_assembly.py` | `assemble_task_note_data` — resolves a task's project slug, parent, subtasks, dependencies, and (V2) archive eligibility (`_archive_year`, gated on `vault_archive_days`) via the live `TaskService`/`ProjectService` into a `TaskNoteData`. `reproject_task` (V2) bundles assemble + narrative-preservation + `write_task` into the one code path shared by `rebuild`, the janitor's changed/sample/archival passes, and the create-on-task seam — none of them can drift on how a note gets refreshed. | ~125 |
+| `roboco/services/vault_intake_engine.py` | `VaultIntakeEngine.run_cycle` — scans the vault's inbox dir for `#roboco`-tagged notes, dedupes via `vault_seen_notes` (path + content-hash), screens the body through `injection_guard.screen_external_text`, extracts a title/description/action-items via a local-model chat call (deterministic fallback: first heading / raw body / checkbox lines), and opens ONE PENDING board-review draft (`source=vault_note`, Product-Owner-assigned, `team=board`) per note. Appends a feedback callout back into the note (best-effort). V2: the frontmatter split + content-hash helpers moved to the shared `foundation/policy/vault_notes.py` (this module now just imports them). | ~350 |
+| `roboco/services/vault_janitor.py` **(new, V2)** | `VaultJanitor.run_cycle` — one state-gated sweep: re-project tasks changed since the last sweep (`TaskService.list_updated_since`, capped/paged, per-item isolated), verify a random stale sample (`sample_stale_tasks`), archive old terminal tasks (`list_archive_candidates`), and (weekly) render the org-report. Dueness is tracked in a JSON state file (`RoboCo/_meta/.janitor_state.json`: `last_sweep`, `last_report_week`, `archive_watermark`), not the loop's own cadence — restart-proof. | ~343 |
+| `roboco/services/vault_kb_engine.py` **(new, V2)** | `VaultKBEngine.run_cycle` — scans the allowlisted `vault_kb_dirs` (default `RoboCo/Notes`), dedups by content hash, screens every note body through the injection guard as a hard GATE (flagged → quarantined, never indexed), and ingests/deindexes into `IndexType.VAULT_NOTES` via `OptimalService.index_vault_note`/`unindex_vault_note`. Defense-in-depth containment: symlinks and any resolved-path escape from the vault root are skipped, independent of the config-load validator. | ~315 |
+| `roboco/foundation/policy/vault_notes.py` **(new, V2)** | Shared pure helpers: `content_hash` (sha256 with every `> [!kind] RoboCo: ...` feedback callout stripped first, so appending one doesn't change what the next scan considers "changed") and `split_frontmatter` (YAML frontmatter + body). Used by both the intake watcher's "drafted" callout and the KB engine's "quarantined" callout — one shared convention instead of two copies drifting. | ~46 |
+| `roboco/services/optimal_brain/indexes/vault_notes.py` **(new, V2)** | `VaultNotesIndexPlugin` — `IndexType.VAULT_NOTES` plugin, mirrors `PlaybooksIndexPlugin`'s shape (`index_note`/`delete_note`/`search_notes`, source URI `vault://<relpath>`). Scope enforced by the KB engine's dir allowlist, not this plugin. | ~70 |
+| `roboco/vault.py` | `python -m roboco.vault {rebuild,relocate}` CLI. `rebuild` re-projects every agent/task/journal-entry/A2A-thread from the DB (now archive-aware via `vault_assembly.reproject_task` — an old terminal task projects straight into `Archive/<year>/`) and materializes `.obsidian/` + `RoboCo/_meta/` from `roboco/vault_assets/` (never overwrites an existing file). `relocate <path>` moves the tree; grafts `RoboCo/` into an existing destination vault without touching its own config. | ~237 |
+| `roboco/vault_assets/` | Packaged templates copied by `ensure_vault_assets`: `.obsidian/` (Dataview, Kanban, graph-group config — V2 adds `Archive`/`Reports` graph color groups) + `meta/` (dashboard + kanban-board + README, V2 adds `Task Board.base` + `Reports.base` for Obsidian's core Bases plugin, and `Sync to your Mac.md`, the Syncthing/SMB/Obsidian-Sync runbook). Dataview dashboard queries now exclude `Archive/`. | — |
+| `roboco/foundation/policy/injection_guard.py` | `screen_external_text` / `detect_injection` — the shared prompt-injection screen-and-neutralize (data path) and hard-deny (interactive-input path) pattern set. V2 reuses it a third time: the KB engine's ingest-time hard gate (quarantine on a hit, vs. the intake watcher's screen-and-still-process posture). | 125 |
 | `roboco/services/gateway/content_actions.py` `curate_vault` | Server-side do-action: Auditor-only, re-materializes a task's note with the Auditor's `narrative` filling `## Narrative`. Inert (`invalid_state`) when the flag is off. | — |
 | `roboco/mcp/do_server.py` `curate_vault` | Do-tool the Auditor calls exactly once per completed root, POSTing to `/api/v1/do/curate_vault`. | — |
 | `roboco/db/tables.py` `VaultSeenNoteTable` | Dedup ledger for the intake watcher: `(note_path, content_hash)` — an unchanged note is never reprocessed; an edited one is eligible again. | — |
+| `roboco/services/task.py` `_materialize_vault_note` / `list_updated_since` / `list_archive_candidates` / `sample_stale_tasks` | V2: the create-time seam + the janitor's three query methods. See `docs/map/task-service.md`. | — |

 ## Data Flow

-**PROJECTION (always-on when the flag is armed).** Three best-effort event seams fire from existing services, never gating the real action: `TaskService._emit_status_transition_audit` → `_touch_vault_frontmatter` patches an EXISTING note's status/team/pr fields in place (a not-yet-materialized note is a silent no-op — full materialization happens at Auditor curation or CLI rebuild); `JournalService`'s entry-write path → `_materialize_vault_note` writes one immutable file per non-private entry; `A2AService.send` → `_materialize_vault_note` appends to a per-thread digest file, deduped per message id via an in-body marker comment. All three import `get_vault_writer()` lazily and catch every exception — a vault failure is logged and swallowed, never surfaced to the caller.
+**PROJECTION (always-on when the flag is armed).** `TaskService.create` (V2) calls `_materialize_vault_note` — best-effort, same swallow-and-log posture as every other seam — so a task's note exists from the moment it's created, not just at curation/rebuild. Three more best-effort event seams fire from existing services: `TaskService._emit_status_transition_audit` → `_touch_vault_frontmatter` patches an EXISTING note's status/team/pr fields in place (now effectively always finds one for any task created post-V2, since materialize-on-create ran; a pre-V2 task without a note is still a no-op here — the janitor's changed/sample passes are what backfill it); `JournalService`'s entry-write path → `_materialize_vault_note` writes one immutable file per non-private entry; `A2AService.send` → `_materialize_vault_note` appends to a per-thread digest file, deduped per message id via an in-body marker comment. All import `get_vault_writer()` lazily and catch every exception.

-**CURATION (root-completion hook, orchestrator-driven).** `AgentOrchestrator._dispatch_vault_curation_work` (one of the 18 tick dispatchers, gated on `obsidian_vault_enabled`) reads `TaskService.list_completed_roots_pending_vault_curation` and calls `_maybe_spawn_vault_curation` per candidate: an in-memory one-shot guard (`_board_dispatched`) plus a durable `vault_curation_dispatched` marker (survives a restart) precede a bindingless Auditor spawn — the root task id is named in the prompt rather than bound as the spawn's active task (the root is already `completed`, so binding would trip the readiness gate's role-for-status check). The Auditor writes one narrative paragraph and calls `curate_vault(task_id, narrative)` exactly once; the verb re-resolves the task's parent/subtasks/dependencies fresh via `assemble_task_note_data` and fully re-materializes the note, filling the `## Narrative` section a deterministic write otherwise leaves as `_Pending Auditor curation._`.
+**CURATION (root-completion hook, orchestrator-driven).** `AgentOrchestrator._dispatch_vault_curation_work` (one of the 18 tick dispatchers, gated on `obsidian_vault_enabled`) reads `TaskService.list_completed_roots_pending_vault_curation` and calls `_maybe_spawn_vault_curation` per candidate: an in-memory one-shot guard (`_board_dispatched`) plus a durable `vault_curation_dispatched` marker (survives a restart) precede a bindingless Auditor spawn. The Auditor writes one narrative paragraph and calls `curate_vault(task_id, narrative)` exactly once; the verb re-resolves the task's parent/subtasks/dependencies fresh via `assemble_task_note_data` and fully re-materializes the note, filling the `## Narrative` section a deterministic write otherwise leaves as `_Pending Auditor curation._`.

-**INTAKE (independently-gated inbox watcher).** `AgentOrchestrator._vault_intake_loop` (both `obsidian_vault_enabled` AND `vault_intake_enabled` required) ticks `VaultIntakeEngine.run_cycle` every `vault_intake_interval_seconds`. Per note under the inbox dir: skip if no `#roboco` tag (frontmatter list or inline `#roboco` token); skip if already seen (path + content-hash in `vault_seen_notes` — an edit changes the hash and re-qualifies); screen the body via `screen_external_text` (wraps it in an untrusted-content envelope, flags any injection-pattern line inline, never removes content); extract title/description/action-items via a local-model chat call against the SCREENED text, falling back to a deterministic first-heading/raw-body/checkbox-line extraction on any local-model failure; open ONE PENDING task (`source=vault_note`, Product-Owner-assigned, `team=board`, `confirmed_by_human=True` — the board routing IS the start gate) capped by `vault_intake_max_open_drafts` (rolling) and `vault_intake_max_per_cycle` (per-tick); append a feedback callout into the source note (best-effort). The draft NEVER starts delivery directly — it takes the identical intake board-review path a chat-confirmed draft would: Product Owner + Head of Marketing review, and only the CEO's `approve_and_start` hands it to the Main PM.
+**INTAKE (independently-gated inbox watcher).** `AgentOrchestrator._vault_intake_loop` (both `obsidian_vault_enabled` AND `vault_intake_enabled` required) ticks `VaultIntakeEngine.run_cycle` every `vault_intake_interval_seconds`. Per note under the inbox dir: skip if no `#roboco` tag; skip if already seen (path + content-hash in `vault_seen_notes`); screen the body via `screen_external_text`; extract title/description/action-items via a local-model chat call against the SCREENED text, falling back to deterministic extraction; open ONE PENDING task (`source=vault_note`, Product-Owner-assigned, `team=board`) capped by `vault_intake_max_open_drafts`/`vault_intake_max_per_cycle`; append a feedback callout (best-effort). Never starts delivery directly — the board-review path is the only door.

-**REBUILD/RELOCATE (operator/CLI, not agent-facing).** `python -m roboco.vault rebuild` walks every agent, then every task (preserving each task's existing `## Narrative` via `writer.existing_narrative` before re-materializing), then every non-private journal entry, then every A2A thread — fully re-projecting from the DB — and materializes the shipped `.obsidian/`/`_meta/` assets if absent. `relocate <path>` moves `RoboCo/` into a destination, refusing if the destination already has a `RoboCo/` subtree (avoids clobbering another vault's own projection).
+**JANITOR (V2, hourly-ticked, day/week-gated).** `AgentOrchestrator._vault_janitor_loop` (gated on `obsidian_vault_enabled` alone) ticks every `JANITOR_LOOP_INTERVAL_SECONDS` (3600, no config knob) and calls `VaultJanitor.run_cycle`. Actual work only happens when the restart-proof state file (`RoboCo/_meta/.janitor_state.json`) says it's due:
+- **Sweep** (due when `last_sweep` is >= 24h stale): `_reproject_changed` re-projects every task touched since the last sweep (`TaskService.list_updated_since`, ascending, paged 100 at a time, capped at `_MAX_REPROJECT_PER_CYCLE=200` per tick, one bad item logged-and-skipped rather than wedging the pass) via the shared `reproject_task`; `_verify_sample` pulls a random 20-task sample of tasks last touched before the sweep window (`sample_stale_tasks`) and repairs any whose note is missing or whose frontmatter status disagrees with the DB (via `touch_task_frontmatter`, not a full re-projection); `_archive_pass` moves terminal tasks past `vault_archive_days` into `Archive/<year>/` (see below). A capped tick advances `last_sweep`/`archive_watermark` only to the last-processed item's stamp (not "now"), so the very next hourly tick — already due again — picks up the tail with no gap. Logs one `vault_drift_repaired` line: `count` (repaired) / `archived` / `failed`.
+- **Weekly report** (due when `last_report_week` != the current ISO week, and `vault_report_enabled` is on): `_run_weekly_report` pulls `MetricsService.get_velocity/get_cycle_time_by_stage/get_bottleneck_distribution/get_rework_metrics` (days=7) + `UsageService.get_summary("7d")`, renders `VaultWriter.write_org_report`, and best-effort notifies the CEO (`NotificationService.send_weekly_report_notification`) — a notification failure never invalidates the already-written note.
+
+**ARCHIVAL (V2, folded into the janitor sweep).** Policy: a terminal (`completed`/`cancelled`) task whose terminal timestamp (`completed_at` else `updated_at` else `created_at`) is older than `vault_archive_days` (default 30; `0` disables archival outright) moves from `RoboCo/Tasks/<project>/` to `RoboCo/Archive/<year>/Tasks/<project>/`. `TaskService.list_archive_candidates(after, before, ...)` returns terminal tasks whose terminal timestamp falls in `[watermark, cutoff)`, paged/capped identically to the changed-task pass (`_MAX_ARCHIVE_PER_CYCLE=200`). The move itself is free: `VaultWriter.write_task` is archive-aware (`TaskNoteData.archive_year` set by `vault_assembly._archive_year`) — it looks up an existing note across BOTH `Tasks/` and `Archive/` by id8, writes the new copy at the archive-aware target directory, and deletes the stale copy if it moved. Alias-based wikilinks (`[[id8|title]]`) mean nothing pointing at an archived task ever breaks. `rebuild` is archive-aware for free (routes through the same `reproject_task`), and the shipped Dataview dashboard + graph color groups exclude `Archive/`.
+
+**KB INGEST (V2, independently double-gated).** `AgentOrchestrator._vault_kb_loop` (BOTH `obsidian_vault_enabled` AND `vault_kb_enabled` required) ticks `VaultKBEngine.run_cycle` every `vault_kb_interval_seconds` (default 900). Per allowlisted dir in `vault_kb_dirs` (default `RoboCo/Notes`; config-load validation in `Settings._validate_vault_kb_dirs` rejects an absolute/`..`-carrying entry or one overlapping `vault_intake_dir` or a reserved projection dir): recursively scan `*.md`, skip a note that's a symlink, escapes the resolved vault root, or exceeds 64KB; content-hash-dedup against the currently-tracked `IndexType.VAULT_NOTES` docs (an unchanged note is skipped); screen the frontmatter-stripped body through `screen_external_text` as a hard GATE — a flagged note is quarantined (skipped, warn-logged, a one-line feedback callout appended, and any PRIOR indexed chunks removed if it was previously clean) rather than indexed; a clean note ingests via `OptimalService.index_vault_note` (bounded to `_MAX_INGEST_PER_CYCLE=50` per tick — the tail waits for the next cycle). A deletion pass deindexes any previously-tracked path no longer seen on disk. Consumers: `roboco_kb_search` picks up `VAULT_NOTES` for free once the enum exists; `MentorService`'s default/general domain search list includes it (labeled "Vault Notes"); `EvidenceRepo.similar_memory` includes it in claim-time briefings (kind `vault_note`), same relevance floor as learnings/playbooks; the panel's KB browser has a full type entry (nav/filter/badge/stats).
+
+**REBUILD/RELOCATE (operator/CLI, not agent-facing).** `python -m roboco.vault rebuild` walks every agent, then every task (via the shared `reproject_task` — archive-aware, narrative-preserving), then every non-private journal entry, then every A2A thread, and materializes the shipped `.obsidian/`/`_meta/` assets if absent. `relocate <path>` moves `RoboCo/` into a destination, refusing if the destination already has a `RoboCo/` subtree.

 ## Config Flags

- `ROBOCO_OBSIDIAN_VAULT_ENABLED` — master switch; off = `VaultWriter` is never invoked from any seam, `curate_vault` returns `invalid_state`, and `python -m roboco.vault` refuses. Config default `false`; both `docker-compose.yml` and `docker-compose.registry.yml` set it `true`.
+- `ROBOCO_OBSIDIAN_VAULT_ENABLED` — master switch; off = `VaultWriter` is never invoked from any seam, `curate_vault` returns `invalid_state`, the janitor/KB loops return immediately, and `python -m roboco.vault` refuses. Config default `false`; both compose files set it `true`.
 - `ROBOCO_VAULT_PATH` (default `/data/vault`) — root directory the vault materializes into; bind-mounted in both compose files.
- `ROBOCO_VAULT_INTAKE_ENABLED` — independent second switch for `_vault_intake_loop`; inert unless the master switch is ALSO on. Config default `false`; both compose files set it `true`.
+- `ROBOCO_VAULT_INTAKE_ENABLED` — independent switch for `_vault_intake_loop`; inert unless the master switch is ALSO on. Config default `false`; both compose files set it `true`.
 - `ROBOCO_VAULT_INTAKE_INTERVAL_SECONDS` / `ROBOCO_VAULT_INTAKE_DIR` / `ROBOCO_VAULT_INTAKE_MAX_PER_CYCLE` / `ROBOCO_VAULT_INTAKE_MAX_OPEN_DRAFTS` — cadence, inbox subfolder, per-cycle origination cap, rolling open-draft cap.
+- `ROBOCO_VAULT_ARCHIVE_DAYS` (default `30`, `0` disables) — age past which a terminal task's note archives during the janitor sweep. Checked only under the master switch — no separate enable flag.
+- `ROBOCO_VAULT_REPORT_ENABLED` (default `true`) — the janitor's weekly org-report + CEO notification. Config default `true` in both compose files (deterministic, no LLM, cheap to leave on).
+- `ROBOCO_VAULT_KB_ENABLED` (default `false`) — master switch for KB ingest; off = `_vault_kb_loop` returns immediately and `IndexType.VAULT_NOTES` stays empty. NAS compose (`docker-compose.yml`) sets it `true`; the public registry compose (`docker-compose.registry.yml`) leaves it `false` (optional engines ship off).
+- `ROBOCO_VAULT_KB_DIRS` (default `RoboCo/Notes`, CSV) — vault-relative folders the KB engine scans. Rejected at config load if absolute, `..`-carrying, or overlapping `vault_intake_dir`/`Tasks`/`Journals`/`A2A`/`Agents`/`Archive`/`Reports`/`_meta`/`.obsidian`.
+- `ROBOCO_VAULT_KB_INTERVAL_SECONDS` (default `900`, min `60`) — KB-engine scan cadence.

 ## Health

-The projection side is zero-risk by construction: every seam is best-effort and DB-free from the writer's perspective (`VaultWriter` takes plain dataclasses, never touches the DB itself), so a filesystem or permission failure degrades to a stale/missing note, never a blocked verb. The intake side is the one path that can reach delivery, and it is triple-gated: the flag pair, the injection screen ahead of both the local-model prompt and the deterministic fallback (so neither ever sees raw unscreened text), and the board-review path itself (a `vault_note` draft is PENDING + board-assigned, never auto-started — the CEO's `approve_and_start` is the only door to the Main PM). The dedup ledger (`vault_seen_notes`) is content-hash keyed, not just path-keyed, so an edited note is correctly re-eligible without needing a delete+recreate. Rebuild is idempotent and additive-safe (`ensure_vault_assets` never overwrites an existing file), so re-running it against a vault the CEO has already customized cannot clobber their edits to `.obsidian/`/`_meta/`.
+The projection side is zero-risk by construction: every seam is best-effort and DB-free from the writer's perspective, so a filesystem or permission failure degrades to a stale/missing note, never a blocked verb. Materialize-on-create closes the V1 gap where the Dataview board only ever showed curated/rebuilt tasks — a fresh task is visible immediately. The janitor is the freshness backstop for everything best-effort seams can miss: it's restart-proof (dueness lives in a state file, not loop cadence — an orchestrator that restarts more often than daily still sweeps exactly once per elapsed day), self-healing against a corrupt/hand-edited state file (any unparseable value degrades to "no state," never a wedged loop), and every per-item drain (changed-task, sample-verify, archive) isolates failures — one bad row is logged and skipped, never aborts the pass, and re-qualifies on its next change or the next sample draw. Per-cycle caps (200 reprojects, 200 archives) mean a first-enable or long-downtime backlog drains in bounded hourly slices via the resume-marker convention (a capped tick advances the marker only to the last item it actually processed) rather than one unbounded burst.
+
+The KB-ingest side is the one path with real security stakes — once a vault note is agent-retrievable, unscreened note text is injection into the fleet's retrieval context, not just a drafting risk. It layers defense-in-depth: the config-load validator rejects a dangerous `vault_kb_dirs` entry outright (can't even start with an escaping/overlapping dir); the engine independently re-checks every allowlisted dir resolves under the vault root before scanning it; every individual note is re-checked for symlink-ness and resolved-path escape before it's read (belt-and-suspenders against a dir-level check being bypassed by a per-file symlink); and the injection guard runs as a hard GATE (not the intake watcher's screen-and-still-process posture) — a flagged note is never embedded, only quarantined with a visible callout so the CEO knows why. Content-hash dedup (shared with the intake watcher's ledger convention) makes both re-scans and the quarantine callout's own append idempotent — appending the callout never itself re-triggers reprocessing.
+
+Rebuild/relocate remain idempotent and additive-safe (`ensure_vault_assets` never overwrites an existing file), so re-running against a CEO-customized vault cannot clobber `.obsidian/`/`_meta/` edits.

 ## What It Is

-RoboCo can project its own state into a human-readable [Obsidian](https://obsidian.md) vault — tasks, journal entries, and A2A thread digests as wikilinked markdown notes — so the CEO can browse the org's memory with a normal notes app instead of the panel alone. It is a **rebuildable projection**, not a second source of truth: every note is derived from DB state and can always be regenerated from scratch. Implemented in `roboco/services/vault_writer.py` (pure markdown materializer), `roboco/services/vault_assembly.py` (DB → materializer dataclasses), `roboco/services/vault_intake_engine.py` (the inbox watcher), and `roboco/vault.py` (the `rebuild`/`relocate` CLI).

 ## What agents actually touch

-Almost everything here is transparent to a working agent — notes get written or patched as a side effect of normal verbs (a status transition, a `note()` call, a `dm()`), never something you call yourself. There are exactly two places an agent interacts with the vault directly:
+Almost everything here is transparent to a working agent — notes get written or patched as a side effect of normal verbs (a status transition, a `note()` call, a `dm()`), never something you call yourself. What changed for you since V1:

-1. **The Auditor's `curate_vault(task_id, narrative)`** — spawned once per completed root task to write the one piece of vault content that isn't mechanically derivable from DB columns: a narrative paragraph on the task's note. See `docs/rag/roles/auditor.md`.
-2. **The vault-intake watcher turning a CEO-authored note into a task you might get delegated.** If the CEO tags a note `#roboco` in the vault's inbox folder, a default-off watcher (`ROBOCO_VAULT_INTAKE_ENABLED`) drafts it into a board-review task (`source=vault_note`) — same shape as a chat-confirmed intake draft, Product-Owner-assigned, `team=board`. It never starts work directly: the board reviews it and only the CEO's `approve_and_start` hands it to the Main PM for real delegation. If you end up working a task with `source=vault_note`, its origin was a note the CEO wrote in their own vault, not a chat.
+1. **Your task has a note from the moment it's created**, not just once curated or rebuilt — `TaskService.create` now materializes it directly. You'll never see a task the CEO can look up in the vault yet you can't.
+2. **A task that gets archived (old + terminal) doesn't lose its links.** The vault moves an old completed/cancelled task's note into `RoboCo/Archive/<year>/Tasks/<project>/`, but every wikilink to it (`[[id8|title]]`) is alias-based, so nothing pointing at it breaks — you'd never notice unless you went looking at the raw file path.
+3. **If `vault_kb_enabled` is on, the CEO's own vault notes are retrievable by you.** Anything the CEO writes under `RoboCo/Notes/` (screened for injection attempts first) is embedded into the knowledge base like any other corpus — it shows up in `roboco_kb_search` / `roboco_ask_mentor` results and in your claim-time institutional-memory briefing, labeled `vault_note` (or "Vault Notes" in mentor output). Treat it exactly like a learning or a playbook: institutional memory, not a directive to follow blindly.
+4. **A weekly org-report note exists** (`RoboCo/Reports/<ISO-week>.md`) — velocity, cycle time by stage, bottlenecks, rework, cost. Deterministic (no LLM), for the CEO's browsing; not something you're expected to author or reference.
+5. **The Auditor's `curate_vault(task_id, narrative)`** — unchanged: spawned once per completed root task to write the one piece of vault content that isn't mechanically derivable from DB columns, a narrative paragraph. See `docs/rag/roles/auditor.md`.
+6. **The vault-intake watcher turning a CEO-authored note into a task you might get delegated.** If the CEO tags a note `#roboco` in the vault's inbox folder, a default-off watcher (`ROBOCO_VAULT_INTAKE_ENABLED`) drafts it into a board-review task (`source=vault_note`) — same shape as a chat-confirmed intake draft, Product-Owner-assigned, `team=board`. It never starts work directly: the board reviews it and only the CEO's `approve_and_start` hands it to the Main PM for real delegation.

 ## Layout and link stability

  Tasks/<project-slug>/<title> (<id8>).md
+  Archive/<year>/Tasks/<project-slug>/<title> (<id8>).md   (old terminal tasks)
  Journals/<agent-slug>/<date> <title> (<id8>).md

 ```

-Every note carries `aliases: [<id8>]` in its frontmatter, so a cross-link is always written as `[[<id8>|<title>]]` — Obsidian resolves it by alias regardless of the target's current filename. A task title edit updates the note's own title line without ever renaming the file or breaking a link elsewhere in the vault. Private journal entries (`is_private`) are excluded from the projection, same as the shared RAG corpus.
+Every note carries `aliases: [<id8>]` in its frontmatter, so a cross-link is always written as `[[<id8>|<title>]]` — Obsidian resolves it by alias regardless of the target's current filename or folder. A task title edit updates the note's own title line without ever renaming the file or breaking a link elsewhere in the vault; an archival move works the same way — it relocates the file, not the identity agents/links reference. Private journal entries (`is_private`) are excluded from the projection, same as the shared RAG corpus, and stay excluded from KB ingest scope too (KB ingest only ever covers `RoboCo/Notes/`, never `Journals`/`Tasks`/`A2A`/`Agents`/`Archive`/`Reports`).

 ## What triggers a write

 Best-effort event seams patch or append on the relevant transition — never a gate, never something that can block the real action:

- A task status transition patches the note's frontmatter (status/team/PR) in place, if the note already exists.
+- **Task creation** materializes the note immediately (deterministic template; the narrative is a placeholder until the Auditor curates it).
+- A task status transition patches the note's frontmatter (status/team/PR) in place.
 - A `note()` (journal entry) writes one immutable file per entry.
 - A `dm()` (A2A message) appends to a per-thread digest file.
+- An hourly-ticked, daily-gated janitor sweep catches anything the above seams missed: re-projects tasks changed since the last sweep, verifies a random sample of older ones, and archives old terminal tasks. This is a backstop, not something your own verb calls need to think about.

 None of these fail your call if the vault write itself fails — it's logged and swallowed.

+## KB ingest — the CEO's notes become retrievable
+
+When `vault_kb_enabled` is on (alongside the master switch), notes the CEO writes under `RoboCo/Notes/` are embedded into a dedicated `IndexType.VAULT_NOTES` corpus on a ~15-minute cycle. Before anything is indexed, the note body is screened for prompt-injection patterns — a flagged note is quarantined (never embedded, a warning callout is appended to it so the CEO sees why) rather than silently indexed. A clean note is retrievable through:
+
+- `roboco_kb_search` (pass no filter, or filter to `vault_notes` explicitly)
+- `roboco_ask_mentor` — company/general domain queries include it, formatted as "Vault Notes"
+- Your claim-time institutional-memory briefing, alongside distilled learnings and approved playbooks, subject to the same relevance floor (nothing injected below it)
+
+Content you retrieve this way is the CEO's own writing — background, decisions, preferences — not a verified fact or a directive. Weigh it the same way you'd weigh a learning: useful context, not gospel.
+
 ## Rebuild and relocate

-`python -m roboco.vault rebuild` re-projects every live entity from the DB from scratch (preserving any existing task's Auditor-authored narrative, since that isn't derivable) and materializes the shipped `.obsidian/` config + `_meta/` dashboards if not already present. `python -m roboco.vault relocate <path>` moves the tree — useful for grafting `RoboCo/` into an existing personal vault without touching that vault's own config. Both are operator/CEO commands, not something an agent runs.

+"""VaultKBEngine — human-authored vault note folders become one more RAG corpus.
+
+V2 item 4 (KB ingest, the headline): ``vault_kb_dirs`` (default
+``RoboCo/Notes``) are scanned recursively every cycle; changed notes
+re-ingest into ``IndexType.VAULT_NOTES`` (``replace_chunks`` makes edits
+idempotent), deleted notes deindex. Never covers Tasks/Journals/A2A/Agents/
+Archive/Reports/_meta/.obsidian or the intake Inbox — config-load validation
+(``Settings._validate_vault_kb_dirs``) rejects an overlapping, absolute, or
+``..``-carrying ``vault_kb_dirs`` entry outright.
+
+Containment is enforced again here as defense-in-depth: an allowlisted dir
+whose resolved path escapes the vault root is skipped (warn-logged) before it
+can contribute a single note, and every note must be a real file (no
+symlinks) whose resolved path stays under the resolved vault root — a
+symlinked ``.md`` pointing anywhere else on disk is never read.
+
+Every note's BODY (frontmatter stripped) is screened through the shared
+injection guard (``foundation.policy.injection_guard.screen_external_text``)
+before it can reach the embedder. Unlike the intake watcher's
+screen-and-neutralize posture, this is a hard GATE: an unflagged note is
+indexed with its raw body (the untrusted-content envelope would pollute
+retrieval chunks with non-note text), a flagged note is quarantined —
+skipped, warn-logged, and marked with a feedback callout so the CEO sees why
+it never made the index. The callout is stripped before hashing (shared
+``foundation.policy.vault_notes`` convention with the intake watcher) so
+appending it never itself re-triggers reprocessing, and the callout's own
+presence is what stops a still-quarantined note from being re-flagged/
+re-appended every cycle.
+
+Dormant unless BOTH ``obsidian_vault_enabled`` AND ``vault_kb_enabled`` are on.

+# Sync this vault to your Mac
+
+The vault lives on the NAS. Three ways to read/edit it from your Mac, best first.
+
+## Option 1: Syncthing (recommended)
+
+Two-way, real-time, no cloud hop. Best if you edit notes on both sides (e.g. the Inbox).
+
+1. On the NAS: install Syncthing — via Docker (a small sidecar container) or your NAS app center if it ships one.
+2. On the Mac: `brew install syncthing` then `brew services start syncthing`.
+3. Open each Syncthing web UI (NAS: its container port; Mac: `localhost:8384`) and add the other as a remote device using its device ID.
+4. On the NAS side, share the vault's root folder (the one containing `RoboCo/` and `.obsidian/`).
+5. Accept the share on the Mac and pick a local folder to receive it into. Open that folder as an Obsidian vault.
+6. Set the share type to **Send & Receive** on both sides so edits on the Mac (e.g. dropping a note in the Inbox) sync back to the NAS.
+7. Add a `.stignore` entry on both devices for `.obsidian/workspace.json`:
+   ```
+   .obsidian/workspace.json
+   ```
+Without this, the NAS and the Mac fight over which panes/tabs are open every time either one writes it — annoying, harmless, but noisy. Everything else in `.obsidian/` (themes, plugin settings) is fine to sync.
+
+Conflicts: Syncthing keeps a `.sync-conflict-*` copy instead of overwriting — the vault's alias-based wikilinks mean a rename or an occasional conflict copy never breaks a link.
+
+## Option 2: SMB mount (simpler, read-mostly)
+
+Good if you mostly just want to read the vault and rarely edit.
+
+1. Share the vault's parent folder over SMB from the NAS (most NAS OSes have this built in).
+2. On the Mac: Finder → Go → Connect to Server (`smb://<nas-address>/<share>`).
+3. Open the mounted folder as an Obsidian vault.
+
+Gotchas:
+- Do not also let iCloud Drive sync the same folder — iCloud and an SMB mount both trying to own file versions corrupts an Obsidian vault's index. Keep the vault off iCloud Drive entirely if it's SMB-mounted.
+- A vault on a network share is slower for Obsidian's search/graph indexing than local or Syncthing-synced disk, and a network hiccup mid-write can corrupt `.obsidian/workspace.json` (harmless — delete it, Obsidian regenerates it) or, rarely, a note being saved.
+- No offline access — if the NAS is down or the Mac is off-network, the vault is unreachable.
+
+## Option 3: Obsidian Sync (paid)
+
+Obsidian's own end-to-end-encrypted sync service. Simplest to set up (no NAS-side install), costs a monthly subscription, and syncs through Obsidian's cloud rather than directly NAS-to-Mac. Worth it if you want the vault on more devices (phone, iPad) with zero extra infrastructure. Otherwise Syncthing is the same result for free, one extra install.

+"""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).
