# Required for real payment processing. Leave empty to use simulated payments.

# From Hyperswitch Control Center (app.hyperswitch.io) > Settings > Developers

# --- TRANSFER RETRY WORKER (v0.701) ---
# Drives failed seller_transfers back to completed when Stripe recovers.
# TRANSFER_RETRY_ENABLED=true
# TRANSFER_RETRY_MAX=3
# TRANSFER_RETRY_INTERVAL=5m

# --- REVERSAL WORKER (v1.0.7 item B) ---
# Drives reversal_pending seller_transfers to reversed by calling Stripe
# Connect Transfers:reversal. Decouples buyer-facing refund UX from
# Stripe-side settlement health. Backoff is exponential (base * 2^retry),
# capped at BACKOFF_MAX.

# --- HYPERSWITCH WEBHOOK LOG (v1.0.7 item E) ---
# Every webhook hitting POST /webhooks/hyperswitch is persisted to
# hyperswitch_webhook_log regardless of signature-valid / processing
# outcome — captures attack attempts alongside legitimate traffic for
# forensics. A daily sweep deletes rows older than this many days.
# HYPERSWITCH_WEBHOOK_LOG_RETENTION_DAYS=90

# --- RECONCILIATION WORKER (v1.0.7 item C) ---
# Periodically sweeps for stuck pending orders and refunds whose
# webhook never arrived. Pulls live status from Hyperswitch, feeds a
# synthesised webhook into the normal dispatcher. Idempotent with
# real webhooks via terminal-state guards on the handlers.

# --- EXTERNAL SERVICES (OPTIONAL) ---
STREAM_SERVER_URL=http://veza.fr:8082
# Must match stream server INTERNAL_API_KEY for /internal/jobs/transcode (P1.1.2)
STREAM_SERVER_INTERNAL_API_KEY=
CHAT_SERVER_URL=http://veza.fr:8081

# --- HLS STREAMING (OPTIONAL, default off) ---
# Enables the HLS endpoints on the backend. When false (default), the player
# falls back to the direct /tracks/:id/stream endpoint with HTTP Range support,
# which works for all tracks but without adaptive bitrate. Set to true to
# activate HLS manifests/segments (requires stream server + transcoding).
# See FUNCTIONAL_AUDIT §4 item 5 for the fallback behaviour.
# v1.0.9 W4 Day 17 : default flipped to true. Set to false to disable
# the HLS transcoder pipeline in lightweight dev / unit-test envs.
HLS_STREAMING=true
# HLS segment storage directory (used only when HLS_STREAMING=true)
HLS_STORAGE_DIR=/tmp/veza-hls

# --- TRACK UPLOAD STORAGE BACKEND (v1.0.8 Phase 0, default local) ---
# Where TrackService.UploadTrack() writes new track files.
#   local — writes to veza-backend-api/uploads/tracks/ (legacy behaviour,
#           works single-pod, doesn't scale multi-pod)
#   s3    — writes to S3/MinIO via S3StorageService. Requires
#           AWS_S3_ENABLED=true and AWS_S3_BUCKET. In production, setting
#           this to 's3' without S3 enabled fails startup with an explicit
#           error (dev/staging warn and fall back to 'local').
# Phase 1 wires this into TrackService; Phase 2 migrates the read path;
# Phase 3 provides a migration CLI for existing local tracks.
TRACK_STORAGE_BACKEND=local

# --- FRONTEND URL ---
# Used for password reset links, email templates, etc.
FRONTEND_URL=http://veza.fr:5173

# --- BASE URL ---
# Public base URL of this backend (used for OAuth callbacks, etc.)
BASE_URL=http://veza.fr:8080

# --- EMAIL (REQUIRED for registration + password reset) ---
# Local dev: MailHog ships with `make infra-up-dev` — the defaults below
# point at it on localhost:1025, with the web UI at http://localhost:8025
# to inspect captured emails.
# Production: override with your SMTP provider (SendGrid, AWS SES, etc.).
#
# v1.0.6: unified on canonical SMTP_* names. The legacy SMTP_USER /
# FROM_EMAIL / FROM_NAME are still accepted as a deprecation fallback
# (backend logs a warning on use; removed in v1.1.0).

SMTP_PORT=1025
