Closes the transcoder's read-side gap for Phase 2. HLS transcoding now
works for tracks uploaded under TRACK_STORAGE_BACKEND=s3 without
requiring the stream server pod to share a local volume.
Changes:
- internal/services/hls_transcode_service.go
- New SignedURLProvider interface (minimal: GetSignedURL).
- HLSTranscodeService gains optional s3Resolver + SetS3Resolver.
- TranscodeTrack routed through new resolveSource helper — returns
local FilePath for local tracks, a 1h-TTL signed URL for s3-backed
rows. Missing resolver for an s3 track returns a clear error.
- os.Stat check skipped for HTTP(S) sources (ffmpeg validates them).
- transcodeBitrate takes `source` explicitly so URL propagation is
obvious and ValidateExecPath is bypassed only for the known
signed-URL shape.
- isHTTPSource helper (http://, https:// prefix check).
- internal/workers/job_worker.go
- JobWorker gains optional s3Resolver + SetS3Resolver.
- processTranscodingJob skips the local-file stat when
track.StorageBackend='s3', reads via signed URL instead.
- Passes w.s3Resolver to NewHLSTranscodeService when non-nil.
- internal/config/config.go: DI wires S3StorageService into JobWorker
after instantiation (nil-safe).
- internal/core/track/service.go (copyFileAsyncS3)
- Re-enabled stream server trigger: generates a 1h-TTL signed URL
for the fresh s3 key and passes it to streamService.StartProcessing.
Rust-side ffmpeg consumes HTTPS URLs natively. Failure is logged
but does not fail the upload (track will sit in Processing until
a retry / reconcile).
- internal/core/track/track_upload_handler.go (CompleteChunkedUpload)
- Reload track after S3 migration to pick up the new storage_key.
- Compute transcodeSource = signed URL (s3 path) or finalPath (local).
- Pass transcodeSource to both streamService.StartProcessing and
jobEnqueuer.EnqueueTranscodingJob — dual-trigger preserved per
plan D2 (consolidation deferred v1.0.9).
- internal/services/hls_transcode_service_test.go
- TestHLSTranscodeService_TranscodeTrack_EmptyFilePath updated for
the expanded error message ("empty FilePath" vs "file path is empty").
Known limitation (v1.0.9): HLS segment OUTPUT still writes to the
local outputDir; only the INPUT side is S3-aware. Multi-pod HLS serving
needs the worker to upload segments to MinIO post-transcode. Acceptable
for v1.0.8 target — single-pod staging supports both local + s3 tracks.

Backend Go:
- Remplacement complet des anciennes migrations par la base V1 alignée sur ORIGIN.
- Durcissement global du parsing JSON (BindAndValidateJSON + RespondWithAppError).
- Sécurisation de config.go, CORS, statuts de santé et monitoring.
- Implémentation des transactions P0 (RBAC, duplication de playlists, social toggles).
- Ajout d’un job worker structuré (emails, analytics, thumbnails) + tests associés.
- Nouvelle doc backend : AUDIT_CONFIG, BACKEND_CONFIG, AUTH_PASSWORD_RESET, JOB_WORKER_*.
Chat server (Rust):
- Refonte du pipeline JWT + sécurité, audit et rate limiting avancé.
- Implémentation complète du cycle de message (read receipts, delivered, edit/delete, typing).
- Nettoyage des panics, gestion d’erreurs robuste, logs structurés.
- Migrations chat alignées sur le schéma UUID et nouvelles features.
Stream server (Rust):
- Refonte du moteur de streaming (encoding pipeline + HLS) et des modules core.
- Transactions P0 pour les jobs et segments, garanties d’atomicité.
- Documentation détaillée de la pipeline (AUDIT_STREAM_*, DESIGN_STREAM_PIPELINE, TRANSACTIONS_P0_IMPLEMENTATION).
Documentation & audits:
- TRIAGE.md et AUDIT_STABILITY.md à jour avec l’état réel des 3 services.
- Cartographie complète des migrations et des transactions (DB_MIGRATIONS_*, DB_TRANSACTION_PLAN, AUDIT_DB_TRANSACTIONS, TRANSACTION_TESTS_PHASE3).
- Scripts de reset et de cleanup pour la lab DB et la V1.
Ce commit fige l’ensemble du travail de stabilisation P0 (UUID, backend, chat et stream) avant les phases suivantes (Coherence Guardian, WS hardening, etc.).
