From be4d001aea13d95bb7cfce23f1f5cd4f2e114033 Mon Sep 17 00:00:00 2001 From: sonpiaz Date: Tue, 19 May 2026 13:28:08 -0700 Subject: [PATCH 1/3] docs(phase-3): offline transcribe routing and model lifecycle Sub-spec for Phase 3 item #2 (offline whisper.cpp path). Locks the contract before bin/transcribe gets a local-mode case. Covers routing priority (WATCH_AUDIO_MODE override + auto-detect order), whisper-cli vs main binary detection, ggml-large-v3-turbo lifecycle (storage, consent prompt, download URL, SHA256 pin), 2 GB disk-space gate, exact invocation contract, transcribe_cost_usd omission rule in local mode, audio-q API-only policy, no-silent- fallback policy, install.sh --with-local flag, 7-case test plan, and the anti-patterns list. Eight new stderr tags ship under the existing v1 append-only promise.

Phase 3 adds a +third path: local whisper.cpp plus a pre-downloaded ggml model. With +it installed, the transcribe step does no outbound HTTP — removing +the structural dependency on any single backend, keeping the tool +working when an upstream is throttled or down, and addressing the +"marketing trojan" perception risk OSS reviewers flag when a CLI +defaults to a hosted provider. + +This document is the contract for the local path. If `bin/transcribe` +drifts, this spec wins. + +--- + +## Routing priority + +`bin/transcribe` makes one routing decision at startup, before any +audio is read.

The script does +not fall back to a different path when the requested one fails — if +the user said `local`, falling back to an API call would silently +violate that intent. + +### When `WATCH_AUDIO_MODE` is unset + +The script picks the first usable backend in this order: + +1. **Local whisper.cpp**, when both: a binary named `whisper-cli` (or + the older `main` — see *Binary detection*) is on `PATH`, **and** + the default model file exists at + `~/.watch-cli/models/ggml-large-v3-turbo.bin`. +2. **Kyma**, when `KYMA_API_KEY` is set. +3. **BYOK Groq**, when `GROQ_API_KEY` is set. +4. **No backend**: exit `2`, stderr tag `missing-config`, message: + + ```text + [transcribe] error: no usable audio backend tag=missing-config + Configure one of: + - export KYMA_API_KEY=… (recommended — https://kymaapi.com) + - export GROQ_API_KEY=… (BYOK direct) + - install whisper.cpp + model (fully offline — see docs/offline-mode.md) + ``` + +Local is preferred over a configured API key when both exist: it costs +nothing per call, leaks no audio to a third party, and keeps working +without a network. Users who prefer the API path on a machine that has +both can force it with `WATCH_AUDIO_MODE=kyma`. + +--- + +## whisper.cpp binary detection + +watch-cli probes two binary names, in order: `whisper-cli` (current +upstream name; shipped by the Homebrew bottle and any whisper.cpp +build from roughly mid-2024 onward), then `main` (legacy name from +older builds, kept as a fallback so existing installs do not break). +Resolution is `command -v whisper-cli` first, `command -v main` +second. First hit wins; the resolved path is captured locally so +debug logs record which binary was used. + +Install paths the implementer should be ready for: + +- **Homebrew (macOS):** package `whisper-cpp` (with hyphen), binary + `whisper-cli`. Bottle does not include a model. +- **Build from source (Linux / any):** upstream uses CMake — + `git clone https://github.com/ggml-org/whisper.cpp ~/.watch-cli/whisper.cpp && cd ~/.watch-cli/whisper.cpp && cmake -B build && cmake --build build -j --config Release`. + Binary at `~/.watch-cli/whisper.cpp/build/bin/whisper-cli`; + `install.sh --with-local` (below) symlinks into + `~/.local/bin/whisper-cli`. + +--- + +## Model lifecycle + +**Default model:** `ggml-large-v3-turbo` — multilingual, ~1.62 GB on +disk, fastest of the large-v3 family on Apple Silicon. Comparable +quality to the hosted `transcribe` alias. + +**Storage path:** `~/.watch-cli/models/ggml-large-v3-turbo.bin`, +overridable via `WATCH_MODELS_DIR`. Multiple models in the same +directory are allowed; only the active model's file is read. + +**How the model gets there — two opt-in paths:** + +1. **At install time:** `install.sh --with-local` prints expected + disk footprint, asks `Y/n`, downloads on confirmation. +2. **At first use:** if `WATCH_AUDIO_MODE=local` is set and the model + file is missing, the script prompts: + + ```text + [transcribe] local mode requested but no model found at + ~/.watch-cli/models/ggml-large-v3-turbo.bin + Download ggml-large-v3-turbo (~1.62 GB)? [y/N] + ``` + + Only explicit `y` proceeds. Anything else (default `N`, blank, + `n`, EOF) → exit `2`, tag `missing-dep:whisper-model`. No silent + network activity ever happens in local mode. + +**Download URL:** + +```text +https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-large-v3-turbo.bin +``` + +Verified as a 302 redirect to a signed HuggingFace CDN URL, +content-length `1624555275` bytes (≈ 1.62 GB), content-type +`application/octet-stream`. Follow redirects (`curl -fL`); report +progress on stderr. + +**Integrity verification:** the script computes SHA256 and compares +against a hash pinned in `lib/model-checksums.sh` (one entry per +known model). Upstream publishes SHA1 only +(`4af2b29d7ec73d781377bfd1758ca957a807e941` for `large-v3-turbo`); +re-hash with SHA256 once at implementation time and pin it in-tree — +SHA256 is what every other watch-cli artifact uses and what +`shasum -a 256` defaults to on macOS. + +Mismatch → exit `1`, tag `model-checksum-mismatch`, message with +expected/actual hashes and instructions to delete the partial file +and retry. The partial file is **not** auto-deleted; surfacing the +path lets the user inspect before losing it. + +--- + +## Disk-space check + +Before any model download, the script calls `df -P` on the target +directory and requires ≥ **2 GB free**. The model is 1.62 GB; a +strict 1.62 GB check fails on filesystems with metadata overhead. + +Insufficient → exit `1`, tag `insufficient-disk`, message: + +```text +[transcribe] error: insufficient disk space tag=insufficient-disk + required: 2 GB at ~/.watch-cli/models/ + available: 0.4 GB +Free at least 2 GB or set WATCH_MODELS_DIR to a different mount. +``` + +--- + +## Invocation contract + +In local mode, `bin/transcribe` runs exactly this command (`$BIN` = +`whisper-cli` or `main` per detection): + +```bash +"$BIN" -m "$WATCH_MODELS_DIR/ggml-large-v3-turbo.bin" \ + -f "$AUDIO" --output-txt -of "$STEM" +``` + +- `-m` is the absolute model path. +- `-f` is the pre-normalized audio file from the existing ffmpeg step + (mono 16 kHz). whisper.cpp accepts WAV and MP3 in current builds; + keep WAV default to avoid the 16-bit-WAV-only constraint some older + `main` builds still enforce. +- `--output-txt -of ` writes the transcript to `.txt`. + Script reads it, strips trailing newline, prints to stdout, unlinks. + +whisper.cpp progress goes to stderr and is swallowed (redirected to +`/dev/null`, or to a debug log when `WATCH_DEBUG=1`). + +### Silent-audio handling + +An empty transcript from whisper.cpp is treated identically to an +empty transcript from any API backend: exit `4`, tag +`transcribe-silent-audio`. Text renders `null` in the `TRANSCRIPT:` +block; JSON sets `transcript` to `null`. The existing pre-flight +silence check (`ffmpeg -af volumedetect` ≥ −60 dB) runs **before** +the whisper.cpp invocation, so digitally silent input short-circuits +without spawning whisper.cpp. + +--- + +## Cost field in v1 JSON output + +The v1 schema declares `transcribe_cost_usd` as **optional**: absent +when the backend reports no cost. Local mode is exactly that case — +no per-call cost, and emitting `0` would collide with "the backend +told us this call was free". So in local mode the script **omits** +`transcribe_cost_usd` from the JSON object entirely. The key is +present in Kyma mode (real number returned), absent in local and in +BYOK Groq mode (no cost metadata). + +Consumers MUST check key presence explicitly. From +[`output-schema.md`](output-schema.md): *"A `0` cost is meaningful +(cached transcript, free tier); an absent cost is 'the backend did +not tell us'."* Same rule applies in local mode. + +--- + +## `audio-q` is API-only + +`audio-q` reasons over the audio scene — tone, music, sound effects, +language, emotion — via a multimodal LLM. There is no local +open-source equivalent at the quality bar shipped today, so watch-cli +does not pretend to support offline `audio-q`. + +When `WATCH_AUDIO_MODE=local` is set and any caller invokes +`audio-q`, the script fails with exit `2`, tag `audio-q-requires-api`: + +```text +[audio-q] error: audio-q has no local backend tag=audio-q-requires-api +Audio scene Q&A requires a hosted model. Either: + - unset WATCH_AUDIO_MODE to use the configured API path, or + - export WATCH_AUDIO_MODE=kyma (or byok) for this call. +``` + +No silent fallback. + +--- + +## Fallback policy + +When local mode fails — model missing, binary missing, audio +unreadable, transcript empty, checksum mismatch — `bin/transcribe` +exits with the matching code from the table below. It does **not** +silently fall back to an API call. A user who chose local chose it +for privacy, cost, or network independence; silent fallback would +ship audio over the wire without consent. Users who want "prefer +local, fall back to API" can wrap `transcribe` and branch on the +exit code themselves — local-mode tags are distinct enough. + +### Local-mode exit-code / tag table + +| Condition | Exit | Stderr tag | +|---|---|---| +| Binary not on `PATH` | `2` | `missing-dep:whisper-cli` | +| Model file missing | `2` | `missing-dep:whisper-model` | +| User declined first-run download prompt | `2` | `missing-dep:whisper-model` | +| Insufficient disk before download | `1` | `insufficient-disk` | +| Downloaded model fails SHA256 check | `1` | `model-checksum-mismatch` | +| whisper.cpp returned non-zero | `4` | `transcribe-other` | +| whisper.cpp returned empty transcript | `4` | `transcribe-silent-audio` | + +All tags are appended to the contract in [`exit-codes.md`](exit-codes.md) +under the same append-only rules as v1. + +--- + +## `install.sh --with-local` + +A new installer flag that bootstraps the local path end-to-end: + +1. **Detect host OS.** +2. **macOS:** if `whisper-cli` missing, print + `brew install whisper-cpp` (package `whisper-cpp`, binary + `whisper-cli`) and prompt before running.

BASH_SOURCE[0] does not dereference symlinks, so `watch` invoked from ~/.local/bin (the install-time symlink) computed ROOT_DIR as ~/.local instead of ~/.watch-cli and failed to source lib/health.sh. Same pattern existed in bin/transcribe, bin/models, bin/audio-q — they happened to work before only because lib/env.sh sourcing was accidentally absent on those paths in earlier phases. Now all four scripts loop readlink until they find the real path. 2. Auto-enabling pipe mode whenever stdin was not a TTY caused the "no args → exit 64" negative test to instead drop into pipe mode with an empty stream and exit 0. CI runs with non-TTY stdin, which is the common case for any script context, so the auto-trigger was unsafe. Pipe mode is now opt-in via --pipe only. Docs and inline comments updated to reflect the explicit-only pipe contract.
