The extraction seam landed on the previous branch but nothing fed it. This adds the daemon that does: every interval it opens one mailbox read-only (EXAMINE + BODY.PEEK, so reading leaves no \Seen behind), fetches the UIDs it has not handed over yet, and posts each message to core over ingest_mail. Core runs the model and writes task candidates; this daemon writes nothing and cannot create a reminder. It is a separate daemon because of the credential. mavpoll set the precedent with the zenmoney token (#125): the module talking to the third party holds the secret, reads it from a file so it never lands in argv, in docker-compose.yml or in shell history, and core never sees it. There is deliberately no -password flag, and a test asserts that. Off unless configured at both ends: without -password-file the daemon refuses to start, and if core has no email block the first ingest returns ErrUnknownMethod, which disables the reader instead of hammering a socket that will keep refusing. A seen-UID state file (0600, atomic write) keeps a restart from re-extracting the whole lookback window; correctness does not depend on it, since capture dedupes on normalised text. Logs are counts and UIDs — no subject, sender or body. Verified with an in-process IMAP server and a fake core: bulk mail is filtered before core is asked, seen UIDs are not re-fetched, a failed ingest is retried next poll, ErrUnknownMethod stops at the first message, and state survives a restart. The live half is untested by design — no IMAP credential exists on this box; setup is written up as QA steps. Vikunja #246

# CLAUDE.md
|
||
|
||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||
|
||
Maven is a self-hosted, privacy-first voice assistant (Russian + English). Go daemons
|
||
talking over unix sockets; one resident small model for routing + phrasing; whisper.cpp STT, piper TTS.
|
||
Deploy target is a Ryzen laptop (homesrv) with Vulkan offload to the Vega iGPU (`n_gpu_layers: 99`,
|
||
compose passes `/dev/dri` + the render gid) — the resident model stays ≤1.7B either way.
|
||
|
||
**Resident model:** currently **Qwen3-1.7B** (`UD-Q4_K_XL`), stock — not yet the CPT'd one.
|
||
It replaced Qwen3.5-0.8B on 2026-07-31 because it measured better on both fixtures we have:
|
||
67.5% vs 59.7% intent-only on the 77-case RU routing fixture, and 20/27 vs 11-17/27 on the
|
||
talk fixture. See `MODEL-BAKEOFF-31-07-2026.md`. It is a Thinking variant, so `n_ctx` is 4096
|
||
— reasoning tokens need the room, and 4096 is what the scores above were measured at.
|
||
|
||
The **target** is still the locally CPT'd **Qwen3-1.7B** (Vikunja #122, training in flight).
|
||
Stock already speaks good Russian; what it gets wrong is the persona — it writes `я рад`,
|
||
masculine, where Maven needs `рада`. That is what the CPT is for.
|
||
|
||
**Do not bother with sub-500M models.** LFM2.5-230M and 350M were measured on 2026-07-31 and
|
||
both are unusable in Russian: the 350M routes at 5.2% (worse than guessing) and answers
|
||
"столица Франции?" with the invented non-word "Сторзит"; the 230M replies to Russian in
|
||
Spanish. Their strong published IFEval/BFCL numbers are English-only. Model files live in
|
||
`/mnt/hdd1/llms`, bind-mounted to `/opt/maven/models/llm` — which **shadows** the repo's
|
||
`models/llm/`, so the LFM2.5 gguf sitting there is not loaded by anything. Swapping the resident
|
||
model is a one-line change to `phraser.model_path` in `deploy/mavend.json`.
|
||
|
||
See `REARCH.md` for the target architecture, `DESIGN.md` for the folded design spec, and
|
||
`AGENTS.md` for local-preview + model-download recipes.
|
||
|
||
## Build & test
|
||
|
||
CGO daemons (`mavend`, `mavsttd`, `mavttsd`, `mavenclient`) need the vendored toolchain
|
||
and libs wired through the Makefile — **do not** call `go build` on them bare, use `make`:
|
||
|
||
```sh
|
||
make build # all 9 binaries
|
||
make build-web # single daemon (pure-Go ones: web/waked/poll/caldav build without CGO)
|
||
make test # go test -race across ./internal/... ./cmd/... with CGO env set
|
||
```
|
||
|
||
Run a single test (must carry the CGO env for packages that touch STT/TTS/voice):
|
||
|
||
```sh
|
||
CGO_CFLAGS="-I$(pwd)/deps/include -I$(pwd)/deps/whisper.cpp/ggml/include" \
|
||
CGO_LDFLAGS="-L$(pwd)/deps/lib -Wl,-rpath,$(pwd)/deps/lib" \
|
||
LD_LIBRARY_PATH="$(pwd)/deps/lib" \
|
||
deps/go/go/bin/go test -run TestName ./internal/router/
|
||
```
|
||
|
||
Pure-Go packages (`router`, `memory`, `mavweb`, …) run under a plain `go test ./pkg/`.
|
||
|
||
## The daemons (`cmd/`)
|
||
|
||
| Binary | Role |
|
||
|---|---|
|
||
| `mavend` | **Core.** Router, phraser, memory, reminders, digestion tick. Owns the DB + IPC socket. |
|
||
| `mavweb` | HTTP UI + PWA (`/dash`, `/history`, `/trace`, `/notifications`, `/tools`); WebAuthn auth. Connects to mavend's socket. |
|
||
| `mavsttd` | Speech-to-text (whisper.cpp, CGO). |
|
||
| `mavttsd` | Text-to-speech (piper subprocess). |
|
||
| `mavwaked` | Wake-word / VAD gate. |
|
||
| `mavenclient` | Voice loop client (mic → stt → core → tts). |
|
||
| `mavpoll` | Telegram long-poll reach. |
|
||
| `mavcaldav` | CalDAV calendar sync. |
|
||
| `mavmaild` | Mail reader (IMAP, read-only). Holds the IMAP password; core never sees it. |
|
||
|
||
Daemons are wired socket-to-socket, not linked. `internal/ipc` is the client/server wire
|
||
protocol; the config in `deploy/mavend.json` (with `${VAR}` env expansion from gitignored
|
||
`deploy/telegram.env`) sets socket paths, model paths, and the phraser/embedder blocks.
|
||
|
||
## Routing — read this before touching the router
|
||
|
||
`internal/router/` has TWO layered engines. **The LLM router is now the default and it is
|
||
on in deploy** — this section used to say it was wired `nil`, which stopped being true on
|
||
2026-07-31.
|
||
|
||
- **LLM router (the intended design, REARCH.md):** the resident Qwen3-1.7B (`llmrouter.go`)
|
||
emits GBNF-constrained structured JSON, and the SAME model phrases replies. Embedder is
|
||
demoted from a routing gate to a RAG hint. Wired at `voice.go:214` via
|
||
`pickLLMRouter(cfg.Voice.UseLLMRouter(), llmClient)`; the flag is `voice.llm_router`
|
||
(`config.go`), `DefaultLLMRouter` is **on**, and `deploy/mavend.json` sets it `true`.
|
||
- **Classifier cascade (the failure floor, not dead code):** `classifier.go` +
|
||
`embedder.go` nearest-neighbour over frozen seed phrases. It runs when the LLM router is
|
||
off, when there is no llama-server to talk to (`pickLLMRouter` logs that and degrades),
|
||
and on any per-turn LLM error. Do not delete it — routing by seed similarity is the known
|
||
cause of weak RU query handling, but a turn must never break on the model.
|
||
|
||
Cascade order: `stage0.go` exact-match fast-path → LLM router (when non-nil) → classifier
|
||
fallback. Any LLM error falls through to the classifier so a turn never breaks on the model.
|
||
|
||
Measured on the 77-case RU fixture (`MODEL-BAKEOFF-31-07-2026.md`): the classifier scores
|
||
36.8% full accuracy at p50 31ms; Qwen3-1.7B scores 67.5% intent-only / 72.7% through the
|
||
cascade at p50 ≈2.7s. Accuracy roughly doubled, latency is ~90× worse, and that trade was
|
||
accepted deliberately. `Confidence: 1.0` used to be hardcoded in `llmrouter.go`, so the LLM
|
||
path could never ask for clarification (6/6 refusal cases missed on the fixture) — Vikunja
|
||
#359. Fixed 31-07-2026 with structural signal (single-token utterance, keyless fact, act with
|
||
no allowlisted fn) feeding the same stage-3 gate the classifier path already had — see
|
||
`gateLLMDecision` in `router.go`. Note the second half of that bug: the LLM branch never
|
||
consulted `r.threshold` at all, so a correct low confidence would have been discarded anyway.
|
||
|
||
Re-measured on the fixture after the fix: **missed clarify 6/6 → 1**, at the cost of 3 false
|
||
clarifies and 2.6pt of full accuracy (72.7% → 70.1%, intent-only 67.5% → 74.0%). Two of the
|
||
three false clarifies are acts the model mis-routed and the gate caught — asking beats wrongly
|
||
executing, so the fixture and the daemon disagree about what is correct there. The third,
|
||
`"поужинал"`, is a real defect: **the single-token rule is an English intuition and does not
|
||
transfer to Russian**, where one word is routinely a whole sentence. Narrow or drop it.
|
||
|
||
## LLM output contract
|
||
|
||
All phrasing paths emit `{"response":"...","mood":"..."}` (parsed in `replier_llm.go` and
|
||
`internal/phraser/llmphraser.go`), with fallback to plain text and the legacy
|
||
`{"body","summary"}`. Mood is a fixed enum. Router prompt is a separate contract:
|
||
`[{"intent":<enum>, key?, value?, text?, verb?}, ...]`, 7 intents (`fact, reminder,
|
||
note, query, act, chat, system`). `llm/check_prompt_parity.py` in the training
|
||
workspace enforces that the Go and relabelling prompts remain identical.
|
||
|
||
## Non-goals (hard constraints)
|
||
|
||
Not a nag, not autonomous. Maven's persona is **feminine** — Russian
|
||
self-reference must use feminine forms — `рада`, not `рад`; `поняла`, not `понял`. The owner
|
||
is male and is addressed informally: "ты", singular, never "вы"/"ваш" and never "он"/"его"
|
||
(she talks TO him, not about him). Pet names ("милый", "дорогой") are forbidden; his name
|
||
("Ками") is not. The eval enforces this: `CheckAddress`, `CheckFeminine` and `CheckCringe` in
|
||
`internal/phraser/eval/checks.go`, scored by `make eval-phrasing`.
|
||
|
||
**"Never phones home" is DEPRECATED** (owner's call, 2026-07-31). It used to be a hard
|
||
constraint and it is not one any more: a 0.8B — and a 1.7B — does not know enough to answer
|
||
world questions, so she needs to read external sources. What replaces it:
|
||
|
||
- **No telemetry, no cloud model, no third-party account.** That part never changes. Nothing
|
||
about Maven is reported to anyone, and inference stays on the box.
|
||
- **Local sources first.** Kiwix ZIMs on homesrv (Wikipedia, ifixit) before anything on the
|
||
network. Reading beats recalling for a small model, and a local read costs nothing.
|
||
- **External search is allowed and off unless configured**, like the weather and telegram
|
||
capabilities.
|
||
- **His notes and facts are never search input.** Looking up why the sky is blue and sending
|
||
his stored personal notes to an upstream engine are different acts. Only the utterance goes
|
||
out, never the persona block, history, or matched notes.
|
||
|
||
## Web UI conventions
|
||
|
||
Server-rendered pages share `cmd/mavweb/static/ui.css` (served at `/ui.css`) and the `nav`
|
||
partial (`navHTML` in `cmd/mavweb/main.go`, `{{template "nav" "<active-page>"}}`). No
|
||
per-page `<style>` beyond true one-offs. Wrap every table in `<div class=scroll>` so wide
|
||
data pans on a phone. Local preview + headless screenshot recipe is in `AGENTS.md`.
