Add GEMINI_API_KEY to docker-compose so it can be set in Portainer.
Fall back to this env var when the DB app_config has no geminiApiKey,
so Gemini TTS works without requiring the user to save the key through
the Settings UI.

Gemini returns raw PCM (audio/L16;codec=pcm;rate=24000), not a real WAV
file with a header, so FFmpeg fails to auto-detect the format. Pass
-f s16le, -ar (from mime type), and -ac 1 explicitly so FFmpeg can
decode the byte stream. Also surface FFmpeg stderr on failure instead
of swallowing it.

Replace the 8-item Google Cloud TTS voice list with 2 Gemini native
voices: Charon (homme) and Kore (femme). Set Charon as the default
when switching to Gemini engine in all four reel pages.
https://claude.ai/code/session_01QBvwHAMZzVYfWvy1U5paat
Replace the texttospeech.googleapis.com call (which requires a separate
GCP project with Cloud TTS enabled and billing) with the Gemini native
TTS endpoint (gemini-2.5-flash-preview-tts). This uses the same Gemini
API key already configured in the app, with no extra GCP setup needed.
Voice mapping: fr-FR-Standard-A/C -> Kore (female), B/D -> Charon (male).
Audio is returned as WAV and converted to MP3 via FFmpeg. Subtitle sync
uses ffsubsync as Gemini TTS does not return word boundaries.
https://claude.ai/code/session_01QBvwHAMZzVYfWvy1U5paat
The TTS preview route hardcoded the Gemini API key to undefined when
calling the ffmpeg service, causing the service to silently fall back to
Edge TTS even when the user selected Gemini. Mirror the lookup already
used in the reel processing route so the selected engine is honored.
https://claude.ai/code/session_01QBvwHAMZzVYfWvy1U5paat
Replace \uXXXX surrogate-pair escapes with the actual emoji characters
in print() calls. Lone surrogates are invalid in UTF-8, causing
UnicodeEncodeError on stdout encode and aborting TTS generation before
the Gemini API call.

- new-reel.tsx was still sending 'voice' parameter instead of 'ttsVoice/ttsEngine'
- This caused sync-info to always fail with 400 'Texte et voix requis' for Gemini users
- ttsSyncService.calculateSyncTiming now accepts ttsEngine parameter
- sync-info route extracts ttsVoice/ttsEngine from req.body instead of voice
- Previously it always fell back to Edge TTS even when Gemini was selected
(because server stored 'fr-FR-Standard-B' but route only used 'voice')
- Add response structure logging to see actual keys returned by Gemini API
- Log timepoints count and first item to diagnose word boundary parsing
- Add 'unexpected timepoint format' warning for easier debugging
- Convert emoji to ASCII-safe versions for container logs
- Edge TTS fallback list now includes fr-FR-RemyMultilingualNeural
- Removed 'Neural not in voice' check that rejected Gemini voices (fr-FR-Standard-A etc) before falling back - these are valid voices and Edge-tts handles them properly
- Improved is_male check to match 'Remy' not 'Remi'
- Store Gemini API key globally in appConfig (single key for all users)
- Add /api/settings/gemini GET/POST/DELETE routes for API key management
- Backend: add tts_engine parameter ("edge" or "gemini") to FFmpeg service
- Backend: add generate_tts_gemini() using Google Cloud TTS REST API
- Frontend: Settings page shows Google Gemini API key input card
- Frontend: new-reel, mobile/new-reel, remotion-video, mobile/remotion-video
pages now have Edge/Gemini engine toggle and French voice selector

- Remove piper_config migration
- Remove Piper TTS settings UI card
- Update "Piper TTS" labels to "TTS — voix activée"
edge_tts is now the only TTS engine, using precise word-boundary timing
Remove Minimax Speech API and Freesound integrations entirely.
Add Piper TTS as the sole TTS provider via configurable HTTP URL.
- Add piper_config DB table (url field, per-user)
- Add GET/POST /api/piper/config routes
- Python: replace generate_tts_minimax with generate_tts_piper (GET ?text=, WAV→MP3)
- Simplify generate_tts_with_subs: piper_url param replaces tts_provider+minimax fields
- Drop ttsVoice/ttsProvider from all UI, API, and background job params
- Settings page: replace Minimax+Freesound cards with single Piper URL input
- Remove freeSoundService init from server startup and CSP headers

Pass GroupId query param to Minimax T2A v2 API — required for paid
plan quota allocation. Without it, Minimax defaults to (0/0 used).
- shared/schema.ts: groupId field on minimaxConfig table
- server/migrate.ts: ADD COLUMN IF NOT EXISTS group_id
- server/routes/reels.ts: fetch and pass groupId alongside apiKey
- server/services/ffmpeg.ts: minimax_group_id in request interface/body
- ffmpeg-service/main.py: GroupId in URL, threaded through all call sites
- client/src/pages/settings.tsx: Group ID input in Minimax settings card
- Python: capture tts_error_msg on exception, return in response
- Python: log tts_provider, minimax_api_key presence before call
- ffmpeg.ts: read tts_error from response, log and return it
- reels.ts: store TTS error in post.generationError for visibility
- Add .min(1) validation to insertOpenrouterConfigSchema
- Strip empty/whitespace-only apiKey before fallback to existing key
- Return 400 if resulting apiKey is empty (forces user to enter valid key)
- Add minimax_config table (migration + schema + storage CRUD)
- Add GET/POST /api/minimax/config routes
- Pass tts_provider + minimax_api_key through ffmpeg service
- Add generate_tts_minimax() in Python using Minimax T2A v2 API
- Fall back to ffsubsync for subtitle sync (no WordBoundary events)
- Add Minimax config card in Settings page
- Add provider toggle (Edge TTS / Minimax) + French voices in new-reel
GET /api/v1/posts - list upcoming scheduled posts with filters
PATCH /api/v1/posts/:id - edit content, schedule, or image
DELETE /api/v1/posts/:id - remove scheduled post and cascading relations

- New POST /api/v1/publish endpoint: download image from URL, create post and schedule it per page
- New GET /api/v1/pages endpoint: list available pages for external callers
- API key auth via X-API-Key header, configurable from admin settings (stored in DB)
- New app_config table (migration included) to store the external API key
- Admin-only settings section (desktop + mobile) to set/revoke the key
- Fallback to EXTERNAL_API_KEY env var if no DB key is configured

Some voices/texts do not produce WordBoundary events from edge_tts.
When word_boundaries is empty, generate_ass_from_word_boundaries returns
without writing the ASS file, causing FFmpeg to fail with ENOENT.
Fallback to the old ffsubsync path when no boundaries are captured.

- facebook.ts: use resolvePublicUrl + getMediaBuffer for reels so missing local files fall back to HTTP fetch.
- scheduler.ts: only delete local video files after the last pending scheduled post for that postId is published.

- ffmpeg-service/main.py: replace ffsubsync path with exact word-boundary timing from edge_tts for TTS subtitles. Karaoke styling preserved.
- server/services/ttsSync.ts: fix word count to match TTS-cleaned text, remove artificial punctuationPause subtraction, strip punctuation tokens from count.
- server/routes/reels.ts: remove redundant ttsSyncService calls in preview/background; word_duration is ignored by Python, these only wasted TTS generations.

Facebook resumable upload START/FINISH phases require multipart/form-data
(not application/x-www-form-urlencoded). Add full raw response logging for
each phase to diagnose any remaining issues (subcode, etc).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Replace simple multipart upload (which fails with error 6000 on large
files) with the 3-phase Resumable Upload API (start → transfer → finish).
This is the recommended Facebook approach for files > ~50 MB and is much
more reliable regardless of file size.

- Add slow zoom/pan (Ken Burns) effect to each image slide, cycling through
8 deterministic presets per image index for natural variety
- CapCut-style captions: semi-transparent pill background + yellow glow on
active word; background/text now only visible while voice is speaking
- Fix Facebook error 6000: pass Node.js Buffer directly instead of unsafe
ArrayBuffer pool-slice conversion which could corrupt the upload payload
- Fix TypeScript error: replace u-flag emoji regex with BMP surrogate pairs

Remotion's headless Chromium cannot reliably fetch http://localhost
inside Docker due to network sandboxing. Instead of HTTP URLs, convert
all local /uploads/... files to data:image/...;base64,... before passing
to inputProps. This is reliable in all environments (Docker, dev, CI).
Audio files remain as HTTP URLs since they are loaded via Web Audio API
which has different network handling.

req.file.buffer is undefined with diskStorage — must read the temp file
from req.file.path using fs.readFileSync instead.

Logo stored as relative /uploads/logos/... was resolving to Remotion's
bundle server (port 3000) instead of the app (port 5555).

Remotion's headless Chromium runs inside the same container as the app,
so it must use http://localhost:PORT to fetch local media files.
The Docker service hostname (socialflow-app) is only reachable from
other containers on the Docker network, not from within the container itself.

Remotion's headless Chromium cannot load relative /uploads/... paths.
Library images were passed as-is, causing "Error loading image" at render time.
Now resolves them using INTERNAL_APP_URL (Docker) or the request host (dev).
