Why:
- Add a real bidirectional streaming TTS path: raw LLM tokens are
forwarded to the upstream model (Volcengine v3 via the unspeech ws
bridge) without client-side segmentation, so the model owns sentence
splitting and audio chunks play as they arrive.
- Move audio endpoints out of /api/v1/openai/. `/audio/voices`,
`/audio/models`, `/audio/voices/streaming` are not real OpenAI public
APIs, and the streaming TTS surface has nothing to do with OpenAI —
keeping them under /openai/ mislabelled the contract.
- Introduce `capabilities.speech.transport` on ProviderDefinition so
future streaming providers (ElevenLabs / Cartesia / OpenAI Realtime)
opt in without touching Stage.vue or the session factory.
- Unify Stage.vue's TTS path through a single StageTtsSession so the
chat-orchestrator hooks no longer branch on provider id.
What:
- apps/server: new ws proxy /api/v1/audio/speech/ws bridges client ↔
unspeech with auth, pre-flight flux check, billing from upstream
session.finished.usage, OTel spans.
- apps/server: audio routes moved from /api/v1/openai/audio/* to
/api/v1/audio/* (hard cutover; 404 sentinel tests added).
- apps/server: new /api/v1/audio/voices/streaming proxy reads voices
from unspeech /api/voices?provider=volcengine.
- apps/server: new STREAMING_TTS_UPSTREAM configKV entry +
scripts/seed-streaming-tts.ts.
- stage-ui: new libs/speech/streaming-pipeline.ts opens one ws per LLM
intent (appendText / finish / cancel + onSentence / onError / onDone).
- stage-ui: new libs/speech/tts-session.ts — StageTtsSession interface
with segmenter and streaming adapters; factory dispatches by
capabilities.speech.transport instead of hard-coded provider id.
- stage-ui: providerOfficialSpeechStreaming with capabilities.speech =
{ transport: 'bidirectional-ws' }; settings page with model/voice
picker + ws-based preview.
- stage-ui: Stage.vue chat hooks collapsed to a single currentSession;
hot-swap watcher cancels mid-session on provider/voice/model change;
unmount cancels and drains playback.
Tests:
- 9 streaming-pipeline tests (happy path / buffered / error / cancel /
truncation)
- 11 tts-session tests (factory branch coverage + adapter contracts)
- 4 audio-speech-ws route tests (forwarding / billing / pre-flight /
config-missing)
- 3 legacy-path 404 sentinels in v1 route tests
- Verification doc updated to reflect automated coverage.
- Added a new PostHog client for capturing server-side business events such as Stripe webhooks and subscription state changes.
- Implemented various tracking functions for pricing funnel steps, character creation, and chat session starts.
- Enhanced the flux meter tests to handle partial charges and report unbilled flux correctly.
- Updated the CharacterDialog and Flux settings pages to track user interactions with analytics events.
- Introduced a mechanism to identify users on PostHog based on authentication state to ensure accurate funnel tracking.
- Added necessary dependencies for PostHog integration in the project.
## Summary
Adds the experimental Godot stage sidecar path for `stage-tamagotchi`.
This PR wires the existing Tamagotchi model selection flow into an
external Godot runtime window. The renderer gates Godot scene input to
VRM models, Electron main materialises the selected model bytes to a
local file, and the Godot sidecar receives the native path over a local
WebSocket bridge before importing and displaying the avatar at runtime.
## What Changed
- Added a typed Godot scene input contract with `format: "vrm"`.
- Added renderer-side VRM-only gating before sending selected model data
to Electron main.
- Added Electron main sidecar management for:
- launching Godot
- starting the local WebSocket bridge
- materialising selected VRM bytes under app `userData`
- forwarding scene apply messages to Godot
- optional remote debugging support
- Added Godot runtime scripts for:
- sidecar startup and WebSocket orchestration
- message envelope parsing
- avatar import and atomic replacement
- runtime VRM import through Godot `GLTFDocument`
- Added engine-local docs for runtime import, live debugging, vendor
patches, and current VRM support boundaries.
- Removed temporary tests after using them to verify the glue behaviour
locally, to keep the review surface smaller.
## Vendor Code Note
A large part of this PR is vendored Godot add-on code, not AIRI business
logic.
The bulk of the added files under:
- `engines/stage-tamagotchi-godot/addons/vrm/**`
- `engines/stage-tamagotchi-godot/addons/Godot-MToon-Shader/**`
comes from V-Sekai Godot VRM / MToon add-ons. These files are required
because Godot plugins are project-local source/assets rather than
package-manager dependencies.
The intended review scope for vendor code is limited to:
- source baseline metadata
- license/plugin config
- Godot-generated metadata notes
- the documented local patch in `addons/vrm/vrm_extension.gd`
The application/runtime code to review is mainly under:
- `apps/stage-tamagotchi/src/shared/eventa/index.ts`
- `apps/stage-tamagotchi/src/renderer/pages/settings/models/`
- `apps/stage-tamagotchi/src/main/services/airi/godot-stage/`
- `engines/stage-tamagotchi-godot/scripts/`
## Current Boundary
This is still an experimental G1 Godot sidecar path.
The runtime scene input contract accepts `.vrm` files only. The current
Godot runtime importer covers the VRM 0.x path used by the local fixture
through AIRI’s runtime bridge over the vendored VRM extension. VRM 1.0
editor import support exists in the vendored add-on, but the sidecar
runtime importer does not yet register the full `VRMC_*` extension set,
so this PR does not claim full VRM 1.0 runtime support.
