## Maven — current state (updated 2026-07-18)

Architecture decision: the target resident router/phraser is the locally
trained Qwen3-1.7B model. Older LFM references below describe the currently
deployed/historical stack, not the target checkpoint. RU CPT has a successful
full-weight checkpoint at step 1000/8077; evaluation and Qwen3 SFT tooling are
tracked in `docs/plans/2026-07-18-qwen3-resident-training-eval.md`.

Consolidated status. The reactive↔proactive core is closed and testable through
the web PWA. The SPEC's open items 1–7 are landed (protocol doc, away-channel
fallthrough, CalDAV poller, quiet-hours schedule, tools enable/disable, note RAG,
passkey step-up); item 8 (multi-user) is deliberately deferred — see the tail.
The two big infra gaps from the jul5 revision are closed on `overnight-jul5`:
**at-rest encryption** (AES-256-GCM, tmpfs working copy — not sqlcipher, see
`internal/store/crypt.go`) and **Docker deployment** (one image, six daemon
containers). The `overnight-jul6` session (now on `master`) closed the biggest
*query-surface* gaps — **calendar querying, general-knowledge answers, and
weather** — plus a populated homelab act allowlist and two pure scaffolds
(dialogue state, long-term-memory vector store). ~15.2k LOC + ~8.5k test, 303
tests, `-race` in `make test`.

### Access model

- **Phone** → needs the wg tunnel to reach homesrv (no homesrv DNS otherwise;
  raw IP or a DNS tweak can bypass, not the default).
- **PC** → uses homesrv DNS, resolves the domains over local-net, **no wg needed**.
- nginx + ufw both scope to `10.42.0.0/24` (wg) + `192.168.1.0/24` (LAN), deny all else.
- **Surface in use now: the web PWA (`mavweb`).** Voice PTT + in-app nudges both ride it.

### Works end-to-end (tested)

- **Reactive voice:** PWA record → Whisper STT (`mavsttd`) → ONNX classifier →
  LFM 2.5-1.2B phraser (llama-server subprocess) → Piper TTS (`mavttsd`) → reply.
  HTTP POST path (mobile-Chrome drops WS for the audio).
- **Capture:** `fact` (EN **and RU** — root-substring recognizers) + `reminder`
  persist through CoreAPI (`source=tap:voice`). This is the substrate the care
  rules read.
- **Notes / query (semantic recall, sqlite — no chroma):** `note` → embed (the
  classifier's ONNX embedder) → `notes` table. `query` → embed → brute-force
  cosine top-k → confidence-gated (below `queryMinScore` 0.55 ⇒ "no note", not a
  guess). **Note RAG (SPEC item 6):** the gated top-k feed the phraser
  (`PhraseQuery`) to compose a natural answer ("вот что я нашла: …") instead of
  a verbatim dump; raw-notes fallback on any LLM error. Stub is deterministic.
- **Monitoring (`/dash`):** mavweb server-renders presence + recent nudges (by
  outcome) + recent facts from the append-only store via CoreAPI. Read-only,
  meta-refresh, no JS.
- **Proactive loop:** 60s dumb ticker, pure predicates over a State snapshot,
  universal gate (quiet-hours/presence/cooldown/snooze/calendar), one-nudge-per-
  tick max-severity, reminders (gate-bypassing), sev4 repeat-til-ack, feedback
  auto-tuner (outcome ratio → bounded cooldown, persisted as `source=feedback`).
- **Rules:** water/meal/break (sev1–2 care), service_down (sev4, `poll:uptimekuma`),
  netdata_critical (sev3, `poll:netdata`).
- **Routines (`internal/routine`):** operator-declared clockwork — the third
  proactive class beside reminders (user-stated) and care rules (world-state).
  Config `routines[]` (cron + literal RU body + severity) fire through the normal
  dispatcher on schedule (an 08:00 briefing, a 22:00 wind-down). Bodies are
  literal (not LLM-phrased ⇒ can't hallucinate); rule name `routine:<name>` so
  they don't pollute the care autotuner; cold-start guard seeds on first sight so
  a restart never replays a missed schedule. Pure `routine.Due`, unit-tested; the
  tick driver holds the last-fired map.
- **Env facts (`mavpoll`):** netdata alarms → `netdata_alarm` (fires immediately
  on a real CRITICAL); kuma monitor_status → `service_down`. Writes only on
  value-change (no append-only churn).
- **Presence:** noisy-OR decay + Schmitt hysteresis. Live via `page_heartbeat`
  (PWA auto-pings `/api/signal` every 30s → present when a tab's open).
- **Delivery:** ntfy / telegram / voice by `f(severity, presence)`; minimal body
  on away channels. PWA subscribes to ntfy over **WebSocket** for in-app nudges.
- **Away-channel fallthrough (SPEC item 2):** when the router picks voice but no
  live session exists at push time (presence guess was wrong), the dispatcher
  reroutes through the AWAY table — sev3→ntfy, sev4→telegram-repeat-til-ack,
  sev≤2→drop — instead of silently dropping. Covers nudges + reminders.
- **Calendar busy (SPEC item 3, `mavcaldav`):** new poller queries a self-hosted
  **Radicale** CalDAV server on an interval, writes `calendar_busy` + event facts
  through CoreAPI (value-change only). The loop gate already consumes `calendar_busy`.
- **Quiet-hours schedule (SPEC item 4):** the gate reads `quiet_hours`; a config
  time window (`voice.quiet_hours`, HH:MM, midnight-crossing handled) now sets it
  on each tick — in addition to the "тихий режим" voice toggle. Both activate quiet.
- **Client protocol (SPEC item 1):** the voice wire format (length-prefixed JSON
  frames) is published in `PROTOCOL.md`, generated from `internal/voice/wire.go`
  so third-party clients don't need the Go source.
- **Passkey step-up (SPEC item 7):** `internal/webauthn` does real WebAuthn —
  ES256/P-256 register + assert, ecdsa signature verification, rpIdHash + UP/UV
  flag binding (UV = the gesture), sign-count regression check. `PasskeySession`
  bumps the auth session L2→L3 for a TTL on assert. mavweb serves `/auth/passkey`
  (enroll + step-up) + the begin/finish endpoints. Crypto is round-trip tested
  (incl. tampered-sig / missing-UV / wrong-origin negatives).
- **Stability:** llama-server orphan leak fixed (`Pdeathsig` kills the child on
  any mavend death); `kill-maven.sh` reaps strays (matches the model, not a
  bogus `llama-server.*maven` pattern); `start-maven.sh` wires `-core` + poller.

### Wired but needs a deploy action (not code)

- **`desk_active`** (strongest presence signal) — `scripts/desk-active.sh` runs
  on the **desk PC** (hypridle-gated systemd timer), posts over wg to mavweb.
- **`mavwaked`** (always-on listening) — needs a systemd user unit on a client
  box (desk PC, pi, etc.) where the mic is attached. Connects to mavend over wg
  or local net via `-addr`. Deferred until a client box is wired with a mic.

Caveats / gotchas:
- **desk_active is a workstation deploy, not code** — 0 facts ever written; presence
  runs on page_heartbeat alone (dash reads "away"/"never at desk"). `scripts/desk-active.sh`
  + a hypridle-gated `maven-desk` timer must be installed on the desk PC (not homesrv).
- **Notes recall needs the ONNX embedder** — under the HashEmbedder floor, cosine is
  lexical (token overlap), not semantic; scores are low, so most RU commands sit under
  the 0.35 route threshold and clarify. Configure `voice.embedder` for confident recall+routing.
  (The floor now at least tokenizes Cyrillic — see below — so it ranks correctly, just weakly.)
- **Switching the embedder model silently breaks old notes** — different dim ⇒
  cosine 0 ⇒ they stop matching; brute-force can't re-embed. Re-embed on a model change.
- **`wg_handshake` is OFF and should stay off** — in this topology the phone only
  runs wg when *outside*, so a fresh handshake means AWAY, not here. The `mavpoll
  -wg` flag exists (defaults `""`) and could later back the spec's "away override"
  by flipping the sign; as a presence-*here* signal it's inverted. desk_active +
  page_heartbeat cover home presence.
- **Cold-start unlock tests are missing** — the key wrap/unwrap code
  (`internal/webauthn/keywrap.go`) and locked-mode IPC gating (`cmd/mavend/main.go`)
  are correct but have **zero test coverage**. The roadmap (item 2.1) required
  three new test cases (wrap/unwrap round-trip, wrong-cred unwrap fails,
  locked-mode IPC rejects non-unlock methods); none were written. `make test`
  is green by omission. Write these before relying on the cold-start path with
  real keys.

### Done since last revision (overnight-jul6, 2026-07-06)

Seven tasks (`SESSION-06-07-2026.md`), one commit each, merged to `master`.
This session was run through **opencode**, not Claude Code (co-author trailer).

Since then (**2026-07-06, second session**):

- **Always-on listening (gap 1, MVP)** — `cmd/mavwaked/`: 825 lines, 10 `-race`
  tests. Energy-based VAD over 30ms windows (same RMS threshold as mavsttd's
  `gateReason`), adaptive noise floor, speech→silence state machine. Captures
  PCM from arecord(1) subprocess, sends `PushToTalk` with `Surface=SurfaceVoice`
  (L0 — no destructive acts). Reply plays through aplay(1). No wake word yet
  (pure VAD trigger); the 30ms frame shape matches silero-vad ONNX input 1:1,
  so swapping energy-threshold for ONNX inference is a local change in vad.go.
  `Makefile` `build-waked` target. Runs on client boxes (not docker/homesrv)
  via systemd user unit; connects to mavend over wg or local net.

Since then (**2026-07-06, third session** — roadmap execution agent):

- **Cold-start unlock (ROADMAP 2.1)** — the at-rest AES key is now wrapped
  (HKDF-SHA256 + AES-256-GCM, stdlib-only — no `x/crypto` dep) with the passkey
  credential's public key and persisted to disk. At boot, if a wrapped key file
  exists AND no env key is set, mavend starts **locked**: the IPC server runs
  but `srv.Check` rejects everything except `MethodAssertStepUp` +
  `MethodUnlock`. A passkey assertion at `/auth/passkey` calls `MethodUnlock`
  with the credential's public key → unwraps the blob → opens the store → wires
  voice/loop/delivery → `srv.SetAPI` swaps the locked stub for the real
  CoreAPI. mavweb's `RegisterFinish` wraps the env key on enrollment;
  `AssertFinish` calls `Unlock` on assertion. Env-key fallback preserved
  (dev/CI path unchanged). **Test gap:** the roadmap required three new test
  cases (wrap/unwrap round-trip, wrong-cred unwrap fails, locked-mode IPC
  rejects non-unlock methods) — none were written. The code is correct but
  untested; `make test` is green by omission, not coverage.
- **Conversation depth (ROADMAP 3.2)** — cross-intent anaphora + fact-by-key
  lookup. `AnaphoraResolver` in `router/slots.go` detects RU pronouns
  (это/он/она/оно/тот/мой + inflected forms). `followUpMerge` now handles
  three cases: same-intent slot inheritance (existing), cross-intent anaphora
  (Query/Fact/Reminder after a Fact with a pronoun inherits the prior key +
  time), and query-after-fact (a query following a fact inherits the key for
  fact-by-key lookup). `Session.History []Turn` added as the multi-turn
  scaffold (capped at 4). 7 new test cases including the exact done-when
  scenarios (anaphora query-after-fact, three-turn break, explicit-key-wins).
- **Routing quality + persona (ROADMAP 4.1/4.4)** — `QueryMinScore` is now a
  config knob (`voice.query_min_score`, default 0.55) instead of a hardcoded
  const. `make download-embedder` fetches Xenova/paraphrase-multilingual-
  MiniLM-L12-v2 (~90MB ONNX) + tokenizer; AGENTS.md documents the embedder +
  libonnxruntime setup. `Persona` field in `VoiceConfig` prepends to every
  LLM system prompt (nudge phrasing, note queries, general knowledge); empty
  = current hardcoded feminine-gendered Russian persona. Also fixed two
  pre-existing data races found by `-race`: `voice/server.go` wg.Add vs
  wg.Wait (accept mutex), `mavweb/server.go` s.api field (atomic.Value).

- **Calendar querying (task 3)** — "что у меня завтра?" now answers from the
  CalDAV facts the poller already writes. Added `store.CalendarEvents(from,to)`,
  a RU date-scope parser («сегодня»/«завтра») in `router/slots.go`, and an
  IPC `CalendarEvents` RPC (api/client/server/wire) feeding the `IntentQuery`
  handler. Empty day → «на сегодня ничего нет». Previously calendar only *gated*
  nudges; it's now queryable.
- **General-knowledge routing (task 4)** — when notes-RAG misses `queryMinScore`,
  the query now falls through to the phraser with an anti-hallucination system
  prompt (`router.KnowledgePrompt`, single tested source) instead of giving up.
  Empty/errored/Stub phraser → «не знаю.», never a fabrication.
- **Weather (task 5)** — new `internal/weather/`: `Provider` interface, a stub
  («погода не настроена»), and a real **keyless Open-Meteo** provider (geocode +
  current_weather, injectable `*http.Client`, mocked in tests — no live network).
  Wired into `IntentQuery` (keywords погода/градус/температура) with a ~5s
  context timeout; selected by `voice.weather.provider` ("open-meteo" | "" → stub).
- **Homelab act allowlist (task 2)** — `voice.tools` seeded with read-only acts
  (`systemctl status`, `docker ps`, `uptime`, `df`, `free`, `journalctl` reads)
  as `destructive:false` and mutating ones (restart/stop/start/reboot,
  docker-restart/stop) as `destructive:true`. Guardrail verified: no dangerous
  verb is `destructive:false`. RU phrasings seeded in `act.txt`.
- **Embedder config validation (task 1)** — a partially-filled `voice.embedder`
  block (some of model/tokenizer/lib paths missing) is now a load error instead
  of a silent fall-through to the Hash floor; the floor fallback logs explicitly.
- **Dialogue state scaffold (task 6)** — `internal/dialogue/`: `Session` +
  TTL `SessionStore` + pure `InheritSlots`. **Now wired** (post-merge follow-up):
  the voice handler carries slots across same-intent turns within a 2-min window
  (`followUpMerge`, unit-tested) — bounded gap-filling, not full multi-turn yet.
- **Long-term memory interface (task 7)** — `internal/memory/`: `Store` interface
  + `InMemoryStore` (cosine). Wired into `IntentNote` (best-effort insert) and,
  post-merge, into `IntentFact` (facts indexed) + `IntentQuery` (read-back after
  notes-RAG misses). In-memory only — no persistent backend yet (gap #8).

Follow-ups (Claude Code, post-merge): gofmt'd `handlers_test.go` (the jul6
verification commit left it misaligned, so `gofmt -l` still flagged it despite the
"all gates green" claim); deduped the task-4 knowledge prompt to the single tested
`router.KnowledgePrompt()`. Tree is now genuinely green (gofmt/vet/303 tests).

### Done since the jul5 revision (overnight-jul5, 2026-07-05)

The overnight session (`SESSION-05-07-2026.md`, 25 tasks) closed the previous
"not built yet" items 1–3 and added feature depth:

- **At-rest encryption** — the on-disk db is AES-256-GCM ciphertext; the daemon
  works on a tmpfs (RAM) plaintext copy, sealed back atomically on close. Wrong
  key / tamper ⇒ fail closed, never a plaintext fallback. Legacy plaintext dbs
  upgrade on first clean shutdown. Key via config/env (`db_key_env`); no KDF —
  raw 32-byte key, base64. The passkey cold-start unlock plugs into the same
  `store.OpenEncrypted` seam later.
- **Docker deployment** — single image, one container per daemon
  (`docker-compose.yml`); only mavend mounts the key + db volume; IPC over a
  shared socket volume. `ipc.DialWait` (boot-order tolerance) + redial-on-drop
  (core restarts don't kill modules). `deploy/README.md` has the runbook.
- **Tests** — mavcaldav, mavttsd, voicesink, mavweb main/handlers covered;
  `make test` runs `-race -coverprofile`.
- **Recurring reminders** — `cron` + `next_fire_ts` on reminders; recurring ones
  reschedule (instead of mark-fired) after successful delivery.
- **Notification digest/batching** — low-severity nudges queue and flush as one
  digest per window/max-items (`digest` config block); stale-reminder bursts on
  boot collapse into a single digest reminder, completed only after delivery.
- **Rule trace engine** — `ExplainTick`/`ExplainGate` record per-rule
  predicate/gate/selection results each tick; served over IPC (`tick_trace`)
  and rendered at mavweb `/trace` ("why didn't she nudge me").
- **Web UI** — new `/history` (facts + revert buttons), `/notifications` (nudge
  history), `/trace` pages; nav links on `/dash`; RU/EN cheatsheet toggle in the
  PWA; manifest icons (`icon.svg`). POST `/tools` now requires an in-process
  passkey step-up when WebAuthn is configured.
- **Revert/undo** — `RevertFact` voids the latest fact for a key (append-only
  void-marker, audit trail intact); exposed at `/api/revert` from `/history`.
- **Tool scopes** — `scope` column on tools, threaded through propose/enable/UI.
  `DisableTool` raised to AuthStepUp alongside Enable.
- **Passkey persistence** — mavweb credentials in a JSON file (`-passkey-file`),
  surviving restarts; rollback-on-persist-failure keeps memory and disk in sync.
- **STT silence gate** — min-duration + RMS floor drop non-speech before whisper
  hallucinates on it (`-min-ms`, `-silence-rms` flags on mavsttd).
- **Housekeeping** — `db_key.env` gitignored (+`.env.example`), `build-caldav`
  target, zero-timestamp "never" fix on /dash.

### Not built yet (ranked by ROI)

1. **Multi-user (SPEC item 8)** — deliberately deferred, see the tail.

Closed (jul6 follow-ups): `/api/revert` now sits behind the same passkey
step-up as POST `/tools`; `go.mod` direct deps (`onnxruntime_go`,
`coder/websocket`, `robfig/cron`) are labeled correctly — `go mod tidy` can't
run here because it walks the vendored `deps/go` toolchain tree.
Purge+rotate leaked db key (#12) — investigated and closed: the key was
**never committed** to git history (gitignored at introduction, no commit
ever tracked `deploy/db_key.env`), so nothing to scrub. File stays on disk
and in deploy env by design — at-rest encryption needs it at boot.

Done earlier (2026-07-03): **act tool executor, store-backed, full flow**
(`internal/tool` + `internal/store/tools.go` + `tools` CoreAPI methods).
- **Execution:** IntentAct runs the matched fn against the store's ENABLED
  allowlist. argv, no shell → STT text can't inject. Live store read, so a
  newly-enabled tool runs without a daemon restart.
- **proposed→enabled→disabled (SPEC item 5):** an act whose verb isn't enabled is
  scaffolded as a `proposed` tool (maven suggests). A human enables it (fills argv
  + destructive) on the authed **`mavweb /tools`** page — never voice — and can
  disable it back to `proposed` (kept in the store, won't run). `EnableTool`/
  `DisableTool` sit at `AuthStepUp`; the gate is now **live** via `PasskeySession`,
  so /tools enable requires a passkey assertion at `/auth/passkey` first.
- **Confirm turn:** a destructive enabled tool replies "выполнить X? да/нет" and
  parks; the next utterance (ru/en yes-no) confirms or cancels (90s TTL).
- **Config:** `voice.tools` seeds enabled tools at boot (editing mavend.json =
  the human enable act); mavweb enables ad-hoc ones on top.
- **Russian:** fixed grammar in reply strings + seed files; maven's self-
  reference is feminine ("she") — [[maven-persona-gender]].

Also fixed:
- **HashEmbedder was blind to Cyrillic** (`tokenize` iterated bytes, kept only
  `a-z0-9`) → every RU utterance embedded to the zero vector → cosine 0 across
  all intents → misrouted to `act` (alphabetical tie-break). Now rune-based
  (`unicode.IsLetter`). This was the real cause of "Найди заметку" (a query)
  landing in `notes`; added note-retrieval query seeds too.
- **Notes are now browsable on `/dash`** — `RecentNotes` plumbed through the
  store + CoreAPI; voice-captured notes were previously only reachable via
  semantic `query`.
Earlier: notes/query recall, `/dash` monitoring, `wg_handshake` poller (NO-OP).

### Gaps — why "voice assistant" is still aspirational (2026-07-06)

What separates Maven today from the thing the spec describes. Dealbreakers
first — these define the category:

1. **Always-on listening is code-complete (MVP).** `cmd/mavwaked` captures
   PCM from arecord → energy-based VAD → PushToTalk with `Surface=SurfaceVoice`
   (L0). Gap narrowed: no wake word yet (pure voice-activity trigger; every
   utterance fires). The 30ms frame shape and 16kHz PCM match silero-vad's
   ONNX input exactly, so a wake-word model swap is a local change in vad.go.
   Hardware: the mic lives on a client box (desk PC, pi, etc.) — never the
   homesrv. Deploy action: systemd user unit on whichever box has the mic,
   connects to mavend over wg or local net.
2. **Conversation is deeper now, still not full dialogue.** The router
   classifies one utterance → one reply, but `internal/dialogue` carries
   context across turns: a 2-min session inherits slots for same-intent
   follow-ups («напомни завтра» → «…позвонить маме»), and cross-intent
   anaphora («запиши что я пил воду» → «когда я это сделал?») now resolves
   RU pronouns (это/он/она/оно/тот/мой + inflections) to the prior turn's
   key for fact-by-key lookup. `Session.History []Turn` is the scaffold for
   real multi-turn. Still missing: LLM-driven dialogue manager (decide
   ask-vs-act), anaphora beyond RU pronouns, single-slot session (single-user
   box). The sub-1B phraser only words replies.
3. **Latency/shape of a turn.** Clip-based STT (record → upload → whisper →
   route → phrase → piper → play). No streaming either direction, no barge-in;
   every exchange is a full round trip.

Capability-class gaps — built but thin:

4. **Act surface is a small argv allowlist.** propose→enable works and the
   allowlist now ships a homelab starter set (jul6 task 2 — status/ps/uptime/
   df/free/logs read-only, restart/stop/reboot gated). Still bounded to what's
   seeded; broadening it is config, not code.
5. **Query answers now cover notes + calendar + weather + general knowledge**
   (jul6 tasks 3/4/5). Calendar querying, keyless Open-Meteo weather, and a
   phraser knowledge-fallback all landed; caveat — general-knowledge quality is
   only as good as the sub-1B phraser, and weather needs `voice.weather.provider`
   set. The cheatsheet and router are now roughly aligned.
6. **Routing quality depends on the ONNX embedder being configured** — the
   HashEmbedder floor makes RU recall lexical/weak; many commands fall to
   "clarify". `make download-embedder` now fetches the multilingual MiniLM
   model + AGENTS.md documents libonnxruntime setup; `voice.query_min_score`
   is a config knob (default 0.55) so the floor can be tuned without recompile.
7. **Presence is effectively one signal** (page_heartbeat); desk_active is
   still an undeployed script — "voice when near" routing runs on a guess.
8. **Long-term memory is now persistent (store-backed), not the spec's chroma.**
   `internal/memory` has a `Store` interface; the daemon now wires
   `store.MemoryStore` (`internal/store/memory.go`) — a **persistent** backend
   in the **same encrypted sqlite db** (survives restarts; recall text inherits
   at-rest encryption, so no plaintext sidecar). Vectors are float32 blobs,
   search is brute-force cosine (fine at single-user scale; ANN is the later
   swap behind the same interface). Notes **and facts** are indexed on capture;
   `IntentQuery` reads it back (after notes-RAG misses, before general-knowledge)
   — fact recall («когда я пил воду?») is its distinct payoff. The in-memory
   impl remains the test/no-store floor. Remaining: an ANN/external index is
   optional-scale, not a gap. Custom TTS voice (kami-picked, replaces the irina
   floor — [[custom-voice-training]]) is still a future item.

Ops footnote: voice-over-web verified 2026-07-06 — mavend binds 0.0.0.0:9100
and mavweb reaches it cross-container at mavend:9100 (nc -z confirmed).
mavpoll uses network_mode=host to reach localhost services (netdata, kuma).

### Future / logged, not now

Custom TTS voice training (kami-picked voice, replaces irina floor); listening
modes 2–3 (meeting-record, ambient-derive).

### Services & layout

- `mavend` (core, IPC unix socket) — store + loop + phraser; the only key-holder.
- `mavsttd` / `mavttsd` — STT/TTS worker modules (unix sockets).
- `mavweb` — PWA bridge (HTTP), `/api/ptt` voice, `/api/signal` presence ingest,
  `/api/ntfy` WS-subscribe config, `/dash` read-only monitoring.
- `mavpoll` — env poller (netdata/kuma → facts via CoreAPI).
- `mavcaldav` — CalDAV poller (Radicale → `calendar_busy` + events via CoreAPI).
- All behind wg + nginx deny-all; no phone-home. CGo only in `mavsttd`.
- Start/stop: `./start-maven.sh [build]`, `./kill-maven.sh`.
- Config: `~/.config/maven/mavend.json` (or `mavend.json` in repo root).

### Key files

- `cmd/mavend/{main,tick,voice}.go` — daemon wiring, loop driver, voice handler
- `internal/loop/{loop,rules,gather,feedback}.go` — proactive engine
- `internal/store/` — append-only facts/reminders/nudges/presence/notes
- `cmd/mavweb/{main.go,dash.html}` — PWA bridge + `/dash` monitoring
- `internal/router/{classifier,slots,stage0}.go` — reactive routing + slot parse
- `internal/delivery/` — dispatcher + ntfy/telegram/voice sinks
- `internal/auth/` — scope/gate/policy; `FloorEnrollment` (same-uid = device
  trust) + `webauthn.PasskeySession` (real step-up for L3)
- `internal/webauthn/`, `cmd/mavweb/webauthn.go` — passkey register/assert
- `cmd/mavcaldav/`, `cmd/mavpoll/`, `scripts/desk-active.sh` — env producers

### Why multi-user (SPEC item 8) is deferred

Not neglect — the one item where doing nothing now beats doing something:

- **No second user exists yet** (the "gf phase"). Building per-user partitioning
  now means code exercised by zero users and validated by nobody — YAGNI.
- **The append-only schema makes it a migration, not a rewrite.** No row is ever
  mutated, so adding `facts/notes/reminders.user_id` later is add-columns +
  backfill-to-"kami" — no reshaping, no dual-write window. Deferral is cheap.
- **The hard part is speaker attribution, and it needs the second voice.** A
  voice-print discriminator (kami vs gf vs unknown) can't be trained or tuned
  with one voice in the house. Plumbing before the model is pipe with no water.
- **It's fenced deliberately** (`DO NOT TOUCH THIS PHASE` in SPEC.md) so an
  autonomous agent doesn't add `user_id` columns while touching the store and
  commit us to a schema before the constraints that shape it exist.
