Root causes found:
1. Scheduler crashing every 15s: assets table has no error_message column.
Fix: remove error_message from UPDATE in scheduler.js (#66 regression).
2. Clip freezing: client-side filmstrip seek loop runs on main thread,
seeks same proxy the player is streaming → both stall → freeze.
Fix: replace browser seek loop entirely with server-side FFmpeg worker.
3. No dedicated filmstrip worker: filmstrip was never pre-built server-side.
Changes:
- services/mam-api/src/db/migrations/018-add-filmstrip-s3-key.sql
Add filmstrip_s3_key TEXT column to assets table
- services/worker/src/workers/filmstrip.js (new)
BullMQ worker: downloads proxy, runs FFmpeg fps filter to extract
28 evenly-spaced JPEG frames, base64-encodes them, uploads JSON
array to S3 at filmstrips/<assetId>.json, stores key in DB
- services/worker/src/workers/thumbnail.js
Queue filmstrip job automatically after thumbnail completes
- services/worker/src/index.js
Register filmstrip worker (concurrency=2), export filmstripQueue
singleton, close it on SIGTERM
- services/mam-api/src/routes/assets.js
- filmstripQueue added
- POST /reprocess?type=filmstrip now supported
- GET /:id/filmstrip returns signed S3 URL for JSON frames
- services/mam-api/src/routes/jobs.js
filmstrip queue visible in Jobs UI
- services/web-ui/public/screens-asset.jsx
Replace browser seek loop with fetch of /assets/:id/filmstrip
→ fetch S3 JSON → render frames. Zero browser-side video seeking.

Bug fixes:
- #91: dockerApi() 10s socket timeout (Docker daemon hang)
- #77: await syncToAmpp() with .catch() — no longer fire-and-forget
- #75: migration 016 — add 'proxy','import' to job_type enum; add 'completed' to job_status
- #73: BullMQ orphan job cleanup on hard asset delete
- #70: batch-trim jobs table gets expires_at; trim-status auto-expires stale rows
- #66: scheduler tick marks stale live assets (>2h) as error
- #63: migration 017 — partial unique index prevents concurrent live asset overwrite
- #61: recorders.js uses getS3Bucket() not stale process.env.S3_BUCKET
- #60: already fixed (copy nulls proxy/thumbnail keys, requeues proxy)
- #40: already fixed (All projects clears openProject)
- #64: already fixed (sourceType/needsProxy handled)
- #90: GET /jobs now includes DB jobs table (trim jobs visible in UI)
- #74: nginx Content-Type header preserved; multer 500MB file size limit
- #68: GET /upload returns in-progress ingesting assets
- #58: /stream and /video endpoints fall back to original file for all video types
- #55: recorder poll .catch() logs auth errors cleanly; redirect stops interval
- #52: thumb-status and thumb-duration moved inside position:relative wrapper
- #50: ProjectCard gets onContextMenu handler with rename/delete menu
- #49: project context menu dismisses on contextmenu + scroll events
Features:
- #93: POST /assets/:id/reprocess?type=proxy|thumbnail — force re-queue any asset
Asset ⋯ menu now shows 'Re-generate proxy' and 'Re-generate thumbnail' buttons
UI:
- Logo: brightness(0) invert(1) filter applied consistently in sidebar, launcher,
and login — white logo pops on dark UI; inline style removed from login.html
