Add a replayable full-system simulator on a fake clock (#284)

A scenario is a JSON file under cmd/mavend/testdata/scenarios: a start
instant, a script of canned model answers, and a list of steps at "HH:MM".
Each step does one thing — say, audio, signal, arrive, tick, fault — and
then asserts on what she said, what was sent, which ecosystem services were
called, and what landed in the intake journal.

Between those boundaries the real components run: the real router cascade
(stage0, the LLM router over a scripted completer, the classifier
underneath it), the real store, the real reactive handler, the real tick
loop, and the same intake-decorated ipc.CoreAPI the daemon wires. What is
faked is only what a test cannot have: the model, the microphone, the
speaker, the delivery sink, and the ecosystem HTTP services.

Time is a single fakeClock threaded into every reader — the handler, the
intake publish stamp and tick(ctx, now) — so there is no time.Now() on the
replay path and a scenario is reproducible. TestSimulatorIsDeterministic
enforces that by replaying twice and diffing the transcripts byte for byte;
advanceTo refuses a step that goes backwards.

Two scenarios ship. morning_missed replays #284's own description: he
appears at the desk, a feed item, a mail candidate and a relayed
notification arrive through the morning, two ticks pass, and the assertions
are as much about nothing being sent at him unprompted as about what she
said. evening_degraded picks up the tier-2 pipeline case #288 deferred
here — a golden WAV through the STT seam to a written fact — and then puts
the ecosystem into 503 and checks that the proactive loop stays quiet and
that intake keeps working without it.

This is test-only code. Nothing in the production binaries changed, so the
daemon behaves identically when no scenario is running.

`make simulate` runs them verbose so the transcript is readable; `make
test` runs them with everything else.

+// mavend/capture.go — core's half of the meeting recorder (Vikunja #253,
+// docs/plans/08-hearing.md).
+//
+// The split: a client that has a microphone (mavenclient, or a phone on the PWA)
+// is told to start, streams frames over ipc.MethodCaptureAppend, and is told to
+// stop. Core keeps the PCM, stores it as a WAV blob under the same media store
+// and the same retention as images, transcribes it through the ONE STT Maven has
+// (mavsttd's whisper.cpp, reused — not a second engine), and summarises the
+// transcript on the resident model in windows that fit n_ctx 4096.
+//
+// # Off unless configured, twice over
+//
+// No `media` block ⇒ nowhere to keep audio ⇒ the four capture methods do not
+// exist. No `capture` block with enabled ⇒ they still do not exist. On an
+// unconfigured box there is no wire path that starts a recording, which is the
+// only guarantee worth making about a capability like this one.
+//
+// # What this file refuses to do
+//
+//   - Nothing listens. There is no VAD hook here, no wake-word branch, no
+//     "start when you hear a meeting". The plan document's keyword-triggered
+//     recorder is refused in internal/capture's package comment for the reason
+//     that applies here too: noticing a keyword requires listening, which is
+//     the behaviour this capability must not have.
+//   - No transcript note by default. The summary is written where he will read
+//     it; the verbatim record of what other people said takes a deliberate
+//     capture.save_transcript.
+//   - The transcript is never search input beyond this box, and the audio never
+//     leaves it at all.

+// Every intake path in Maven already converges on three writes, and all three
+// are ipc.CoreAPI methods —
+//
+//	WriteFact   ← POST /api/ambient, mavcaldav, mavpoll's zenmoney + wg reads,
+//	              /api/signal presence probes, the RSS/crawl watermarks
+//	WriteNote   ← the RSS poller, the page crawler, meeting transcripts,
+//	              image descriptions
+//	CaptureTask ← the voice path, the web form, and the mail reader
+//
+// — so decorating that ONE interface with a publish covers the lot without a
+// caller knowing about events at all. cmd/mavmaild, cmd/mavcaldav, cmd/mavpoll,
+// cmd/mavweb and the in-core feed/crawl/capture/vision workers are unchanged:
+// they call the same interface they always called, and it now also narrates.
+//
+// The exception is cmd/mavend/mail.go, which reaches past the interface to
+// st.CaptureTask directly. It publishes explicitly; see mailIntake.ingest.
+//
+// # Production behaviour when nobody is watching
+//
+// A nil *event.Bus makes Publish a no-op, and newIntakeAPI with a nil bus
+// returns the wrapped API unchanged, so there is not even a decorator on the
+// call path. The journal is memory-only and is never consulted by the tick
+// loop, the router, or delivery — nothing Maven says depends on it. It is a
+// read surface (`/events`, `recent_events`) and an observation seam for the
+// simulator.
+//
+// # What is deliberately NOT here
+//
+// No dispatch. An event is a report that something arrived, never an
+// instruction to speak: "a feed item appeared" becoming a notification is the
+// nag this repo refuses. Digestion may one day read the journal; it will still
+// go through internal/loop's rules and the severity/presence routing table.

+// (Vikunja #284, 20-07-2026-BACKLOG.md item 7).
+//
+// # What it is
+//
+// A scripted day, replayed through the real mavend code paths, with every
+// boundary faked and the clock under the scenario's control. A scenario is a
+// JSON file in testdata/scenarios; the harness reads it, builds a world, walks
+// the steps in order, and asserts on what actually happened:
+//
+//	what Maven SAID          — the reply text of every utterance
+//	what was SENT            — every delivery.Sendable the dispatcher emitted
+//	what ARRIVED             — the unified intake journal from #283
+//	what TOOLS were called   — the recorded requests against fake Praxis/Nexis/Hexis
+//	what did NOT happen      — expect_no_send / expect_no_call, first-class
+//
+// The last one is the point. Maven's hard constraints are mostly negative —
+// not a nag, not autonomous, nothing executed without confirmation — and a
+// harness that can only assert on things that happened cannot test any of
+// them. "Nothing was sent" is an assertion here, not an absence of one.
+//
+// # Determinism
+//
+// No time.Now() runs inside a replay. The scenario names a start instant, each
+// step names a wall-clock offset from it, and the harness advances a fakeClock
+// to that offset before running the step. Every clock reader in the world —
+// the handler's `now`, the tick loop's `tick(ctx, now)`, the intake journal's
+// publish stamp — is wired to that clock. Two runs of the same file produce
+// the same transcript, and a scenario about 08:35 does not behave differently
+// at 03:00 in CI.
+//
+// The tick is driven by the scenario, not by a ticker: tick() already takes
+// `now` as an argument, so the only thing the daemon's ticker contributed was
+// wall-clock timing, which is exactly what a replay must not have.
+//
+// # Why this shape and not a binary
+//
+// Vikunja #288 (golden-audio STT) deferred its tier-2 "audio → STT → router →
+// phraser" scenarios to this task, and asked that they reuse a fixture format
+// rather than inventing a third. A scenario here can name a WAV from
+// cmd/mavsttd/testdata and the harness will feed it through the STT seam. As a
+// test it runs under `make test` on every change, which a separate binary
+// would not.
+//
+// # Production is untouched
+//
+// Every file this task adds is a _test.go file or testdata. There is no
+// simulator in the daemon, no flag, no config key, and no code path that
+// checks whether a simulation is running. The seams it uses — stt.Transcriber,
+// tts.Synthesizer, router.Completer, delivery.Sink, ipc.CoreAPI, the
+// event.Bus from #283 — all already existed for the production wiring.

+// Two things this file deliberately does not do:

+// docs/plans/01-email-reader.md).
+//
+// Every so often it opens one IMAP mailbox read-only, fetches the messages it
+// has not read yet, and hands each one to core over ipc.MethodIngestMail. Core
+// runs the extraction on the resident model and writes what comes back as task
+// CANDIDATES he reviews on /tasks. Nothing here writes to the store, nothing
+// here can create a reminder, and nothing here speaks.
+//
+// Why a separate daemon rather than a loop inside mavend, when extraction has
+// to happen in mavend anyway: the credential. mavpoll set the precedent with the
+// zenmoney token (#125) — the module that talks to a third party holds the
+// secret, reads it from a FILE so it never appears in `ps`, in
+// docker-compose.yml or in shell history, and core never sees it. Core learns
+// that mail exists only as message text on one IPC method; it cannot connect to
+// the mailbox even if it wanted to, and a compromised core yields no mail
+// password.
+//
+// Off unless configured: without -password-file there is nothing to run, and
+// the daemon says so and exits. If core has no `email` block the very first
+// ingest comes back ErrUnknownMethod and this daemon stops polling instead of
+// hammering a socket that will keep refusing.
+//
+// Mail is personal, so the log is counts and UIDs: how many messages were
+// fetched, how many were bulk, how many candidates came back. No subject, no
+// sender, no body, ever — reviewing a candidate is what /tasks is for.

+`mavend.json` ships without a `feeds` block, which means no RSS/Atom feed is
+fetched and no outbound request is made. Switching it on is adding the block:
+
+```json
+"feeds": {
+  "poll_interval": "30m",
+  "max_items": 5,
+  "max_age": "24h",
+  "sources": [
+    { "name": "habr", "url": "https://habr.com/ru/rss/best/daily/",
+      "category": "технологии", "exclude": ["реклама"] }
+  ]
+}
+```
+
+What it does and does not do:
+
+- items are written as notes with source `rss:<name>`, visible on `/dash`;
+- **nothing is announced.** She reads them back when asked — "что нового в
+  лентах?", "что нового по технологиям?" — and never on arrival. There is no
+  severity or channel knob here on purpose;
+- the fetcher is allowlisted to the hosts of the configured feeds, plus any
+  `allow_hosts`. It refuses non-http(s) schemes and every private address
+  (loopback, the LAN, the `10.42.0.0/24` wg range, cloud metadata). It caps the
+  response at 2 MiB and redirects at 3, and makes at most one request per host
+  per second. See `internal/webfetch`;
+- how far each feed was read is stored as a config fact `rss:latest:<name>`, so
+  a restart does not re-note yesterday's headlines.
+
+### Reading a page (`crawl`, also off by default)
+
+There is no `crawl` block either, so no page is fetched. Two halves, separately
+switched:
+
+```json
+"crawl": {
+  "on_demand": true,
+  "interval": "6h",
+  "max_runes": 4000,
+  "watches": [
+    { "name": "changelog", "url": "https://example.org/changelog", "interval": "12h" }
+  ]
+}
+```
+
+- `on_demand` lets her read a page he names in the utterance: "посмотри
+  https://example.org/x — что там?". The page becomes context for his question,
+  and only the URL leaves the box. Without a URL nothing is fetched, so this is
+  a fallback and not a habit;
+- `watches` re-reads a fixed list on its interval and writes a note when the
+  text changed. Like the feeds, it announces nothing;
+- the answer path sits **last** in the query chain, behind his memory, his notes
+  and (once wired) the local Kiwix ZIMs. A local read costs nothing;
+- `robots.txt` is fetched first and obeyed with no override; a `Disallow` is a
+  refusal she says out loud. `Crawl-delay` is honoured;
+- same guarded fetcher as the feeds: allowlist/denylist, no private addresses,
+  size cap, redirect cap, timeout, one request per host per second;
+- dedup state is the config fact `crawl:hash:<name>`.

+## Updating her (`mavupdate`, Vikunja #249)
+
+Off unless configured, and there is deliberately no button for it. There is no
+IPC method, no web route, no timer and no act that starts an update — the trigger
+is a human running `mavupdate` on the host, which needs shell access, a strictly
+higher bar than the step-up passkey gate that guards `/tools`. She cannot update
+herself; she can be updated. Nothing here ever fetches code: the new version is
+whatever you pulled into the working tree yourself.
+
+Add an `update` block to `mavend.json` (mavend ignores it — only the CLI reads
+it), with paths as they exist **on the host**, not inside a container:
+
+```json
+"update": {
+  "source_dir": "/home/kami/apps/Maven",
+  "install_dir": "/home/kami/apps/Maven",
+  "snapshot_dir": "/var/lib/maven-snapshots",
+  "binaries": ["mavend", "mavweb", "mavsttd", "mavttsd", "mavwaked",

+  "health_timeout_sec": 120
+}
+```
+
+`snapshot_dir` must be outside `install_dir` (a restore must not read from what
+the install writes) and `health_socket` is required: an update that cannot check
+its own result cannot roll itself back, so the config is refused without one.
+
+Then:
+
+```sh
+mavupdate -config deploy/mavend.json verify        # make build + make test, deploys nothing
+mavupdate -config deploy/mavend.json apply -yes    # snapshot, verify, install, restart, health-check
+mavupdate -config deploy/mavend.json list          # what you can roll back to
+mavupdate -config deploy/mavend.json rollback -yes # restore the previous artifacts and restart
+```
+
+`apply` refuses to start if she is not already answering — otherwise a failed
+update and a box that was already broken are indistinguishable afterwards. On any
+failure after the install it restores the snapshot, restarts, and checks again;
+if that also fails it says so loudly and names the directory to copy back by hand.
+The database is never snapshotted or rolled back (see the package comment in
+`internal/update`); schema compatibility is `store.Migrate`'s job.

 # Plan: Vision — Image Understanding Capability
 
-**Goal:** Maven can "see" — accept images (from mavweb upload, Telegram, or filesystem paths), run vision inference via a local or remote multimodal model, and answer questions about the image content or extract structured information.
+**Goal:** Maven can "see" — accept images (from mavweb upload, Telegram, or filesystem paths), store them, run inference via a **local** multimodal model, and answer questions about the image content or extract text from it.
 
-**Done when:**
-- Vision model backend is configurable: local multimodal LLM (e.g., LLaVA, Qwen-VL via `llama-server` mmproj) or remote API
-- `internal/vision/` package handles image preprocessing, model inference, result parsing
-- Voice/text commands like "что на картинке?" or "прочитай текст с экрана" route to the vision handler
-- Extracted information can be written as facts/notes through `ipc.CoreAPI`
-- Telegram image messages are processed through the same pipeline
+**Status (2026-08-01):** intake, storage, config seam and the provider are shipped. The
+describing half is **BLOCKED on a model download** — see "What is blocked" below.
 
-**Scope:**
-- New `internal/vision/` package — image loader (Go stdlib `image` + `golang.org/x/image`), inference client
-- New config block: `voice.vision` in `config.Config` — `{enabled, provider, model_path, mmproj_path, remote_url}`
-- Router intent extension: new `IntentVision` or reuse `IntentQuery` with a vision flag
-- Reuses `internal/llm.Client` for API-compatible backends (OpenAI-compatible vision API)
-- Reuses `internal/ipc.CoreAPI` for writing extracted data
+## What shipped
 
-**Steps:**
-1. Create `internal/vision/provider.go` — `Provider` interface with `Describe(image []byte, prompt string) (string, error)` and `ExtractText(image []byte) (string, error)`
-2. Implement `LocalProvider` — spawns `llama-server` with mmproj, sends multimodal chat completion requests
-3. Implement `RemoteProvider` — calls an OpenAI-compatible vision API endpoint, reuses `internal/llm.Client`
-4. Create `internal/vision/processor.go` — image preprocessing (resize, format conversion to JPEG/PNG, base64 encoding)
-5. Wire vision into `cmd/mavend/voice.go:reactiveHandler` — detect vision intent from router (new `IntentVision` or a `Slots.HasImage` flag)
-6. Add IPC method `MethodDescribeImage` for programmatic access (mavweb upload, telegram bot)
-7. Add vision config block to `config.Config` and wire in `cmd/mavend/main.go`
-8. Test with a local multimodal model: send an image via mavweb, verify description and text extraction
+| Piece | Where |
+|---|---|
+| Blob store (content-addressed, retention-pruned) | `internal/media/store.go` |
+| Image decode / flatten / downscale / JPEG | `internal/media/image.go` |
+| `Provider` seam + `Disabled` floor + `LocalProvider` | `internal/vision/vision.go` |
+| Store-then-describe orchestration, re-runnable | `internal/vision/intake.go` |
+| Config blocks `media` and `vision` | `internal/config/config.go` |
+| IPC method `describe_image` (`AuthRead`) | `internal/ipc/{wire,api,client,server}.go`, `internal/auth/policy.go` |
+| Daemon wiring + hourly retention prune | `cmd/mavend/vision.go` |
+
+`internal/media` is deliberately shared: hearing (#253) and speaker recognition (#255) have
+the same intake problem — a blob arrives, gets stored, gets described — and they store their
+audio in the same place under the same retention.
+
+## Design decisions worth knowing
+
+**Store before describe.** `Intake.Accept` writes the blob to disk *first*, then asks the
+model. If the model is missing or broken — which is this box's actual state — the answer is
+"it's kept, I can't read it yet" with a content-addressed id, and `Intake.Rerun(id, question)`
+describes it later. Nothing is lost to a missing model.
+
+**No `RemoteProvider`.** The original step 3 called for "an OpenAI-compatible vision API
+endpoint". Refused. The surviving hard constraint in CLAUDE.md after "never phones home" was
+deprecated is *no cloud model, inference stays on the box*, and a photo of his flat is the
+worst possible exception. `vision.NewLocal` therefore validates the endpoint at construction:
+loopback, a private IP, or `localhost`. A hostname is refused too — it could resolve anywhere,
+and resolving it would mean trusting DNS with his pictures.
+
+**Blobs are not in the database.** The sqlite store is small, encrypted and read every tick;
+a 40 MB blob has no business there. What lands in the database is the *text* the blob produced,
+as an ordinary note (`source: media:image:<id-prefix>`), and only when the caller asks for it
+(`save_note`). Glancing at a screenshot is not the same act as remembering it.
+
+**Images are never search input and never embedded.** Only the derived description
+participates in recall, and only after he can see it as a note.
+
+**Retention is enforced by a loop, not by a promise.** `media.retention` defaults to 7 days
+and `cmd/mavend` prunes hourly, starting at boot. A store that grows forever would be the real
+failure mode of this capability.
+
+**No webp.** The stdlib has no webp decoder and this repo takes no new dependencies (the box
+is offline). `media.SniffImage` recognises webp well enough to refuse it *by name*, so the log
+says "webp is not supported" instead of "not an image". Telegram sends webp for stickers; that
+is a known gap, not a mystery.
+
+**Text extraction is not a second method.** "прочитай текст с картинки" is a prompt. A VLM has
+no separate OCR mode to select, and a second interface method would only duplicate the first.
+
+## What is blocked, and on what
+
+There is **no vision-capable gguf and no mmproj file on this box**. Checked 2026-08-01:
+
+```
+/mnt/hdd1/llms/{Bonsai,LFM2.5,llama3.2,ministral,nemotron3-nano,qwen3,qwen3.5}
+```
+
+— sixteen ggufs, all text-only, no `*mmproj*` anywhere. The resident Qwen3-1.7B is text-only
+by construction, so vision needs a *second* model. The ≤1.7B ceiling in CLAUDE.md is about the
+resident router/phraser, not about a second model loaded on demand — but iGPU VRAM still is,
+so keep it small.
+
+To unblock, download one pair to `/mnt/hdd1/llms/vision/` (bind-mounted to
+`/opt/maven/models/llm`), a gguf **and** its mmproj:
+
+- `Qwen2.5-VL-3B-Instruct` (Q4_K_M + `mmproj-F16.gguf`) — the safe default; reads Russian, and
+  its OCR is the best of this size class.
+- `SmolVLM2-2.2B-Instruct` — smaller and faster, weaker at Cyrillic text in images.
+- `moondream2` — smallest, English-only in practice. Do not bother, per the sub-500M lesson.
+
+Then run a second llama-server on 8081 with `--mmproj`, point `vision.endpoint` at it, and
+walk the QA steps on Vikunja #252.
+
+## Config
+
+```json

+
+Both absent by default. No `media` block ⇒ `describe_image` does not exist at all; a `media`
+block with no `vision` block ⇒ images are stored and honestly not described.
+
+## Still open
+
+- **Router intent.** "что на картинке?" does not route anywhere yet. Adding an intent is
+  premature while nothing can answer it; the IPC method is the surface a Telegram photo or a
+  mavweb upload calls today.
+- **Telegram photo path** in `mavpoll` (download the file, call `DescribeImage`).
+- **mavweb upload page** and a `/media` listing so stored blobs are visible and deletable from
+  the authed surface.

-# Plan: Hearing — Audio Stream Monitoring & Meeting Summarization
+# Plan: Hearing — Meeting Capture & Summarisation
 
-**Goal:** Maven can "hear" ambient audio from workpc — microphone input during meetings, system audio — and on demand (or on trigger) produce transcripts, summaries, or extract action items. A typical use case: "Maven, запиши встречу" starts capture, "хватит" stops it, and Maven writes a summary note.
+**Goal:** "Maven, запиши встречу" starts a recording, "хватит" stops it, and she writes a
+summary note. The audio stays on the box, is pruned by retention, and nothing is recorded that
+nobody asked for.
 
-**Done when:**
-- `internal/audio/capture.go` — remote microphone capture client (receives PCM stream from workpc over WebSocket or the existing voice TCP protocol)
-- `internal/stt/` — streaming transcription (uses existing `stt.Transcriber` interface, extended with streaming support)
-- Meeting capture triggered by voice command (IntentCapture) or configurable keyword ("maven record")
-- Raw audio is either streamed to STT in real-time or saved to a WAV file and transcribed after capture ends
-- Transcription + LLM summary is written as a note (`source:capture:meeting`) through `ipc.CoreAPI`
-- New `mavheary` module (`cmd/mavheard/`) — the workpc-side agent that captures mic/speaker audio and streams it to mavend
+**Status (2026-08-01):** the recorder, the storage, the chunked transcription, the map-reduce
+summariser, the config seam and the four IPC methods are shipped and tested. What is not
+shipped is the workpc-side microphone agent and the router intent — see "Still open".
 
-**Scope:**
-- New `cmd/mavheard/` — workpc-side agent: captures microphone (PortAudio or ALSA `arecord`), streams over WebSocket to mavend
-- `internal/audio/` extended with capture types: `MicCapture`, `SystemCapture`, `FileCapture`
-- `internal/stt/stt.go` extended with `StreamingTranscriber` interface (or reuse existing with chunked input)
-- Router: new `IntentCapture` intent for start/stop commands
-- Reuses `internal/llm.Client` for summarization
-- Reuses `internal/voice/server.go` TCP protocol for streaming audio
+## What shipped
 
-**Steps:**
-1. Create `cmd/mavheard/main.go` — workpc-side daemon: captures microphone via `arecord` pipe or PortAudio, opens WebSocket or TCP connection to mavend, streams PCM frames
-2. Create `internal/audio/capture.go` — `Capture` interface: `Start()`, `Stop()`, `AudioCh <-chan Audio`; implement `MicCapture` (reads from `mavheard` stream) and `FileCapture` (reads WAV)
-3. Extend `internal/stt/stt.go` — add `TranscribeStream(ctx, audio <-chan Audio) (string, error)` to `Transcriber` interface; `Stub` returns empty; `Remote` forwards chunks to worker socket
-4. Add `IntentCapture` to `internal/router/intent.go` — slots: `Action` ("start"/"stop"/"status"), `Duration`
-5. Wire capture handler in `cmd/mavend/voice.go:reactiveHandler` — start = spawn goroutine receiving audio, stream to STT; stop = finalize, send to LLM for summarization, write note via `WriteNote`
-6. Add capture config to `voice` block in `config.Config` — `{capture_enabled, capture_timeout}`
-7. Test with a recorded WAV file — simulate a meeting, verify transcription + summary note is created
+| Piece | Where |
+|---|---|
+| Session state machine: start / append / stop / abort / status | `internal/capture/capture.go` |
+| Map-reduce summarisation against `n_ctx` 4096 | `internal/capture/summarize.go` |
+| Audio blobs in the shared store, pruned by `media.retention` | `internal/media` (from #252) |
+| Config block `capture`, off by default | `internal/config/config.go` |
+| IPC `capture_start` / `capture_append` / `capture_stop` / `capture_status` | `internal/ipc/{wire,api,client,server}.go` |
+| Authority: the three write methods `AuthWrite`, status `AuthRead` | `internal/auth/policy.go` |
+| Daemon wiring, note write, STT reuse | `cmd/mavend/capture.go` |
+
+The audio lands in the same content-addressed blob store as images, under the same retention
+loop, because #252 and #253 have the same intake problem and solving it twice would mean two
+directories to remember to prune.
+
+## The refusals, and why
+
+**Nothing listens.** The original step 8 called for capture "triggered by voice command
+(IntentCapture) **or configurable keyword ('maven record')**". The keyword half is refused.
+Noticing a keyword requires listening to the room continuously, which is precisely the
+behaviour this capability must not have, and the refusal is in the code rather than in a
+comment: `Recorder.Append` is the only way audio enters, and it returns `ErrNoSession` unless
+someone explicitly started a session. Audio arriving at an idle core is dropped, not buffered
+"just in case".
+
+**Off unless configured, twice over.** No `media` block ⇒ nowhere to keep audio ⇒ the four
+methods do not exist. No `capture` block with `enabled: true` ⇒ they still do not exist. On an
+unconfigured box there is no wire path at all that begins a recording. That is the only
+guarantee worth making here, and it is the reason the hooks use the nil-hook ⇒
+`ErrUnknownMethod` pattern rather than an in-handler check.
+
+**A forgotten session ends itself.** `max_minutes` defaults to 120 and is checked on every
+append, not on a timer that could be missed. Past the cap `Append` returns `ErrExpired`
+permanently, so a client that ignores the error cannot grow the recording; the audio collected
+before the cap is kept and `Stop` still works.
+
+**"Забудь, не записывай" leaves nothing behind.** `capture_stop` with `discard: true` throws
+the session away without storing, transcribing or summarising anything — not a blob with a note
+saying it was abandoned. Nothing.
+
+**The transcript is not saved by default.** The summary is written where he will read it; the
+verbatim record of what other people said in a room is a heavier thing to keep and takes a
+deliberate `save_transcript: true`. The audio blob is pruned by `media.retention` either way.
+
+**No second STT.** Step 3 of the original plan extended the `Transcriber` interface with
+streaming. Not needed and not done: whisper.cpp already runs as `mavsttd`, and `internal/capture`
+takes the ordinary `stt.Transcriber` the voice path already holds (exposed as
+`voiceWiring.transcriber`). Long recordings are handed over in five-minute windows —
+`chunkAudio`, cut on sample boundaries — for the same reason whisper itself works in 30-second
+windows: an hour of PCM in one call either times out or blocks the voice path for minutes.
+Capture with voice off is refused rather than degraded, because storing hours of unreadable
+audio of other people is worse than not recording.
+
+**Not `AuthStepUp`.** Recording people is invasive enough to argue for the top rung, and it is
+still wrong: step-up needs a passkey gesture, which the voice path cannot make, so
+"запиши встречу" could never work by voice — the only way he will actually use this. `AuthWrite`
+plus the off-unless-configured gate is the honest combination.
+
+## Long audio against a 4096-token context
+
+The resident model is a Thinking variant at `n_ctx` 4096, so an hour of transcript does not fit
+in one prompt and never will. `summarize.go` does map-reduce and nothing cleverer: split the
+transcript on sentence boundaries into 3000-rune windows (about 1100 Qwen tokens of Russian,
+leaving room for the persona block, the reasoning and the answer), summarise each, then
+summarise the summaries. A transcript that fits in one window skips the reduce step.
+
+Truncation was the alternative and is rejected: a truncated meeting summary reads as complete
+and is not, and he would act on it. Past `max_chunks` (40, roughly the two-hour cap) the
+transcript *is* cut, and the summary says so in the note.
+
+Two degradations are deliberate and both are reported rather than hidden:
+
+- No llama-server ⇒ transcript, no summary. The words exist.
+- The reduce call fails ⇒ the per-chunk summaries are returned joined. Real work, not thrown
+  away over the last call.
+
+The map and reduce prompts contain no first person at all, so the persona's feminine-form rules
+have nothing to get wrong in them; the reply she actually gives him is phrased by the ordinary
+replier, which does carry the persona.
+

+}
+```
+
+Both absent by default. `capture` alone does nothing without `media`.
+
+## Still open
+
+- **`cmd/mavheard`** — the workpc-side microphone agent. Deferred, not refused: the core half
+  is the part with the invariants in it, and a mic client is straightforward once there is a
+  stable wire to stream at. It should be an explicit-start process, not a resident one, for the
+  same reason the recorder has no keyword trigger. The four IPC methods are the wire it will
+  use; `mavenclient` already has the mic plumbing to borrow.
+- **Router intent.** "запиши встречу" / "хватит" does not route anywhere yet. It needs the
+  `system` intent plus slots, and it needs care: "хватит" is also how someone tells her to stop
+  talking, so the recorder's stop and the speech barge-in must not collide.

 # Plan: Speaker Recognition
 
-**Goal:** Maven can distinguish between different speakers on the voice channel — recognize known voices (the user, family members) and tag facts/notes/transcripts with a speaker identity.
+**Goal:** Maven can tell who is speaking on the voice channel, and tag what she writes with
+who said it.
 
-**Done when:**
-- Speaker embedding extractor (e.g., ECAPA-TDNN or a simple MFCC + GMM) runs on incoming voice PCM before STT
-- Embedding is compared against enrolled speaker profiles (stored as vectors in the `memory_vectors` table alongside semantic memory)
-- Unknown speakers are enrolled on first interaction (prompt: "кто это?")
-- All voice fact/note writes are tagged with `speaker:<id>` in the value/source metadata
-- Speaker identity is available as context to the router, phraser, and replier ("ok, <name>")
+**Status (2026-08-01, Vikunja #255):** the enrolment half is shipped. The recognising half is
+**BLOCKED on a model download** — there is no speaker-embedding model on this box, and one
+was not invented to fill the gap. See "Blocked, and on what" below.
 
-**Scope:**
-- New `internal/speaker/` package — enrollment, recognition, embedding extraction
-- Reuses `internal/store.MemoryStore` for speaker vector storage (same `memory_vectors` table, different `source` prefix)
-- Reuses `internal/audio` for PCM preprocessing
-- Integration point: `cmd/mavend/voice.go:HandlePushToTalk` — speaker ID extracted before STT, passed through context
+## What shipped
 
-**Steps:**
-1. Research speaker embedding approaches — simplest floor: MFCC + cosine similarity via `github.com/mjibson/go-dsp` or a pre-trained ONNX model (SpeechBrain ECAPA)
-2. Create `internal/speaker/recognizer.go` — `Recognizer` interface: `Identify(pcm []float32) (SpeakerID, confidence)`, `Enroll(id, pcm)`
-3. Create `internal/speaker/store.go` — speaker profile CRUD via `store.MemoryStore`: `Insert("speaker:<id>", embedding, meta)`, `Search(embedding, k)`
-4. Create `internal/speaker/enroll.go` — enrollment flow: capture N seconds of audio, extract embedding, prompt for name via TTS + STT round-trip
-5. Wire into `cmd/mavend/voice.go:HandlePushToTalk` — run speaker ID on the PCM before STT; pass speaker ID through `context.Context` to `applyAction`
-6. Tag all voice-written facts/notes with speaker ID — `Source` becomes `tap:voice:speaker:<id>` or metadata field
-7. Add IPC methods `MethodEnrollSpeaker`, `MethodListSpeakers`, `MethodRemoveSpeaker`
-8. Add speaker config block to `voice` in `config.Config` — `{speaker_recognition: true, model_path}`
-9. Test with 2+ recorded voice samples — verify correct identification and rejection of unknown speakers
+| Piece | Where | State |
+|---|---|---|
+| `Recognizer` — identify, list, get, forget | `internal/speaker/recognizer.go` | done; `Identify` answers `ErrDisabled` until a model exists |
+| Enrolment — several samples, averaged, re-normalised | `internal/speaker/enroll.go` | done |
+| Profile shape, id validation, cosine similarity | `internal/speaker/speaker.go` | done |
+| Profile storage as `speaker:<id>` vectors | `internal/memory` `Catalog` + `internal/store/memory.go` | done, no schema migration |
+| Config block, off by default | `internal/config` `SpeakerConfig` | done |
+| `enroll_speaker` / `list_speakers` / `forget_speaker` | `internal/ipc` | done, absent unless configured |
+| Authority rows | `internal/auth/policy.go` | done — enrol step-up, forget write, list read |
+| Daemon wiring + honest startup log | `cmd/mavend/speaker.go` | done |
+| Embedding backend | `newSpeakerEmbedder` | **BLOCKED** — returns nil, seam only |
+| Tagging voice writes with the speaker | `cmd/mavend/voice.go` | not wired; nothing to tag with yet |
+
+## Blocked, and on what
+
+A voiceprint needs a speaker-embedding model. The box was searched: `/mnt/hdd1/llms` holds
+sixteen ggufs across seven families and every one of them is a text model. There is no ECAPA,
+no x-vector, no titanet, no wespeaker, and no `.onnx` under `/mnt/hdd1` at all. There are also
+no enrolment samples, because nothing has ever recorded any.
+
+To unblock, two things are needed and neither can be done from inside the repo:
+
+1. **A model.** SpeechBrain ECAPA-TDNN exported to ONNX (`speechbrain/spkrec-ecapa-voxceleb`,
+   192-dim) is the usual choice and runs on CPU in well under a second for a few seconds of
+   audio. Download it per the recipe in `AGENTS.md`, put it beside the other models so the
+   bind mount picks it up, and point `speaker.model_path` at it.
+2. **An implementation of one function.** `newSpeakerEmbedder` in `cmd/mavend/speaker.go` is
+   the entire seam: give it an ONNX session that turns `audio.Audio` into a `[]float32` and
+   `Identify` starts working. Nothing else changes — not the store, not the protocol, not the
+   authority table, not the handlers. `internal/onnx` already loads the e5 embedder, so the
+   runtime wiring exists to copy.
+3. **Enrolment samples**, three or more per person, recorded deliberately.
+
+### Why there is no fallback
+
+The original plan offered "a simple MFCC + GMM" as the floor. That is refused. MFCC cosine
+distance is a channel and loudness detector as much as a voice detector: it will happily match
+two different people who sit at the same distance from the same microphone, and it drifts when
+the room changes. A general classifier that is sometimes wrong is a nuisance; a **biometric**
+that is confidently wrong writes false claims about named people into his memory, and then
+those claims get recalled as fact. For this capability a bad floor is worse than none, so the
+shipped state is honest absence: `speaker.Disabled`, `ErrDisabled`, and a startup line saying
+so.
+
+## The refusals, and why
+
+- **Unknown speakers are NOT enrolled on first interaction.** The plan's fourth "done when"
+  bullet asked for exactly that, with a TTS "кто это?" prompt. It is refused in
+  `enroll.go`'s doc comment and there is no request shape in the protocol that could express
+  it. Enrolling a voice is taking a biometric of a person; doing it automatically to whoever
+  walks past the microphone does it to guests who are not party to the exchange, and a
+  synthesised question into a room is not consent from whoever happens to answer. Enrolment is
+  an explicit act: an id, a name, and samples recorded for the purpose.
+- **One sample is not enough.** Three separate utterances and nine seconds minimum. A profile
+  built from one sentence encodes that sentence as much as the person, and the threshold then
+  behaves unpredictably against everything else.
+- **An unknown voice stays unknown.** Below threshold, `Identify` returns `ErrUnknown` naming
+  the closest profile in the error text for diagnosis, never as an answer. Guessing who is in
+  the room is how false memories about people get written.
+- **Deletion is one authority rung below enrolment.** Everywhere else in `policy.go` the
+  destructive direction is gated at least as hard as the constructive one. Here that would be
+  backwards: getting rid of a biometric must never be the harder half.
+- **The voiceprint never crosses the socket.** `ListSpeakersResp` carries ids, names, dates
+  and sample counts. The vector stays in core.
+- **Off unless configured.** No `speaker` block ⇒ the three methods answer
+  `ErrUnknownMethod`. There is no wire path on a default box that takes a voiceprint.
+
+## Storage
+
+Profiles live in the existing `memory_vectors` table under the `speaker:` id prefix, as the
+plan intended, so there is no migration. What that needed was a wider interface than
+`memory.Store`: `memory.Catalog` adds `ByPrefix` and `Delete`. `Delete` is the load-bearing
+one — a voiceprint someone asked to be rid of has to actually go, and a search-only store
+cannot do that. `InMemoryStore.Insert` also became an upsert by id, matching what the
+persistent store already did, so re-enrolling replaces a profile instead of stacking a second
+one behind the first.
+
+Profiles do not collide with note or fact vectors: they are only ever read through
+`ByPrefix("speaker:")`, and a note search never returns one because the prefix is not in its
+query path.
+
+## Config
+
+```json
+"speaker": {
+  "enabled": true,
+  "model_path": "/opt/maven/models/spk/ecapa-voxceleb.onnx",
+  "lib_path": "/opt/maven/lib",
+  "threshold": 0.7,
+  "min_seconds": 2.0
+}
+```
+
+`Recognizes()` requires both `enabled` and a `model_path`, so a half-filled block reads as off
+rather than as a capability that fails every turn. With `enabled` and no model the daemon still
+attaches the three methods — profiles can be created, listed and deleted — and logs that
+recognition is blocked.
+
+## Still open
+
+- The embedding backend (above). Everything below waits on it.
+- **Tagging voice writes.** `Profile.Source("tap:voice")` already produces
+  `tap:voice:speaker:kami`, which is the shape step 6 asked for, but nothing calls it yet:
+  with no recogniser there is no id to tag with. When the model lands, the hook is in the
+  voice path before STT.
+- **Speaker as router/phraser context.** Same dependency. Note the persona constraint when it
+  arrives: Maven addresses the owner informally and speaks to him, so "ok, <name>" needs care
+  for anyone who is not him.
+- **An enrolment surface.** The three IPC methods exist; no page drives them. Enrolment is
+  step-up, so it belongs on `/dash` behind a passkey, with a per-profile forget button next to
+  each row — that button is the reason `list_speakers` exists.
+- **A speaker column on the meeting recorder** (#253). Attributing lines in a transcript is
+  the obvious pairing, and it is the place where getting attribution wrong is most damaging,
+  so it waits for a real model too.

+  a query source (`queryWeb` in `actions_query.go`, last in the chain, behind
+  Kiwix once that is wired), not an action he commands. Nothing needs a new wire

+- **Notes, not facts.** A page's text is not a fact about him. Only the dedup

+
+**No new dependency.** The vendored tree has no `x/net/html`, no `goquery` and

+// The output of this file can only ever become rows in `tasks` with status
+// "candidate" (store.TaskCandidate), written through the one intake seam
+// (ipc.CaptureTaskReq, Vikunja #130). That bound is the whole design:
+//
+//   - No reminder. A reminder FIRES; it speaks to him unprompted. A 1.7B that
+//     misreads "встреча была в четверг" as a future appointment would then wake
+//     him up about it. A candidate that is wrong is a line on a review page he
+//     dismisses in one click, which is the correct cost of a model being wrong
+//     about someone's mail.
+//   - No fact. A fact is a claim Maven will later recite as true. Nothing read
+//     out of a marketing mail deserves that standing.
+//   - No calendar event, no note, no action. Extraction writes candidates or
+//     writes nothing.
+//
+// The due date the model may return is stored on the candidate (tasks.due_ts),
+// which no scheduler reads — it is there so the review page can sort by it.
+//
+// Privacy: the mail text goes to the resident model on this box and nowhere
+// else. It is never search input (CLAUDE.md: "his notes and facts are never
+// search input" — mail is the same class), and Evidence keeps only the subject
+// line, so the review page shows him where a candidate came from without the
+// store growing a copy of his mailbox.

+// Things arrive at Maven from a lot of directions: a relayed Android
+// notification (POST /api/ambient), a mail the reader extracted candidates
+// from (ingest_mail), an RSS item, a changed page the crawler noticed, a
+// zenmoney spend, a CalDAV event, a wg handshake that means he is home, a
+// photo he sent, a meeting she was asked to record. Each of those grew its own
+// shape, its own storage decision and its own log line. Nothing could answer
+// "what came in today, from where" without reading eight packages.
+//
+// An Event is that answer: one flat, source-agnostic description of "something
+// arrived". It is deliberately NOT a new storage layer and NOT a new transport.
+// Every intake path keeps writing exactly what it wrote before — a fact, a
+// note, a candidate task — and additionally describes what it did as an Event.
+// The envelope is a VIEW over intake, not a replacement for it, which is why
+// adopting it did not require touching eight callers.
+//
+// # What it is not
+//
+//   - Not a command. An Event is a report of something that happened; nothing
+//     in Maven executes one. Digestion may read them; it may not be driven by
+//     an event alone, because "a thing arrived" is not "a thing must be said".
+//   - Not durable. The bus is a bounded in-memory ring. An event's durable
+//     consequence is the fact/note/task the intake path already wrote; the
+//     envelope is the recent-history window on top. A restart losing the ring
+//     loses nothing that mattered.
+//   - Not a secret store. Body carries what the intake path was already willing
+//     to log or store. Nothing puts a mail body, an IMAP password or a
+//     voiceprint in here, and callers must keep it that way.
