Remove outdated process sections from several backlog markdown files and add new backlog items for AI chat step limits, endpoint status config, and API key field UI improvements.
Add docs/backlog/stt-providers-and-async.md: how to add new synchronous STT
request formats (Deepgram, native Gemini, ElevenLabs) via the explicit
sttApiStyle axis, which providers are inherently async and don't fit the
current sync model, and a target job-based async architecture (BullMQ job
table, sync+async unification, polling -> push -> live streaming) with the
migration path and security/cleanup considerations.
Add docs/streaming-dictation-plan.md — a design document for true
"text appears as you speak" dictation via the OpenAI Realtime API.
- Maps the current batch dictation flow (client MediaRecorder -> single
blob -> POST /ai-chat/transcribe) and why streaming is impossible there.
- Documents the Realtime API contract (transcription session, ephemeral
token, pcm16 audio, input_audio_buffer.append, input_audio_transcription
delta/completed events, server_vad).
- Recommends a server-side WS proxy transport (key stays server-side,
SSRF-guarded, provider-agnostic via sttBaseUrl) over direct browser
WebRTC, and a ProseMirror decoration for interim text with final-only
commit to avoid polluting Yjs collab/history.
- Covers config additions, AudioWorklet PCM16 capture, security per repo
conventions, edge cases, phased rollout, risks, and impacted files.
This document outlines the removal of non‑functional DOCX, PDF, and Confluence
import options that relied on a private EE module. It records the completed
frontend changes and lists the remaining backend cleanup tasks.
