+# Capability-Routed GPU Worker Pool + Job Node Attribution
+
+Date: 2026-05-28  | Status: approved (design), pending implementation
+
+## Problem
+All transcode/proxy jobs run on a single zampp1 worker configured with
+`NVENC_ENABLED=` (empty) -> CPU libx264, despite a Tesla P4 in the box.
+zampp2's L4 runs no worker (0% util). No visibility into which node/GPU ran a
+job. Idle hardware: Tesla P4 + 2x Quadro P400 (zampp1), L4 (zampp2).
+
+## Goals
+1. Use all GPUs, routed by capability (heavy encodes on strong cards, light
+   decode-only jobs on weak cards).
+2. Distribute jobs across nodes automatically.
+3. Show which node + GPU ran each job in the Jobs UI.
+Non-goals: autoscaling, custom scheduler beyond BullMQ competing-consumers,
+multi-GPU selection inside one worker process.
+
+## Current architecture (facts)
+- BullMQ on shared Redis; queues already type-named: proxy, thumbnail,
+  filmstrip, conform, trim. mam-api enqueues by type -> NO mam-api change.
+- worker/src/index.js creates a Worker per queue in one process; per-queue
+  *_CONCURRENCY envs already exist.
+- proxy.js picks gpu_codec || (gpuEnabled ? h264_nvenc : libx264) and falls
+  back to libx264 on GPU encode failure (proxy.js:181).
+- Chain: proxy -> thumbnail -> filmstrip. Workers are competing consumers.
+
+## Design
+
+### Tiers (by queue subscription)
+- HEAVY: subscribes proxy, conform, trim. Cards: Tesla P4 (zampp1), L4
+  (zampp2). NVENC_ENABLED=true -> h264_nvenc.
+- LIGHT: subscribes thumbnail, filmstrip. Cards: 2x Quadro P400 (zampp1).
+P400s never subscribe to heavy queues, so a weak card cannot bottleneck a heavy
+job. Strong cards do not subscribe to light queues in v1 (clean tiers; revisit
+if light backlog ever starves while P4/L4 idle).
+
+### Worker change (only code change)
+Add WORKER_QUEUES env (comma list) to worker/src/index.js: only create Workers
+for listed queues; unset = all (back-compat). No GPU-selection code change —
+each container pinned to one GPU via NVIDIA_VISIBLE_DEVICES (sees it as dev 0).
+
+### Topology
+zampp1 (docker-compose.yml + gpu overlay):
+- worker-p4    : VISIBLE=<P4 uuid>,   NVENC_ENABLED=true, WORKER_QUEUES=proxy,conform,trim
+- worker-p400a : VISIBLE=<P400a uuid>, WORKER_QUEUES=thumbnail,filmstrip
+- worker-p400b : VISIBLE=<P400b uuid>, WORKER_QUEUES=thumbnail,filmstrip
+zampp2 (docker-compose.worker.yml + gpu overlay):
+- worker-l4    : VISIBLE=<L4 uuid>,   NVENC_ENABLED=true, WORKER_QUEUES=proxy,conform,trim
+  needs REDIS_URL / DATABASE_URL / S3_* in zampp2 .env pointing at zampp1.
+Pin by GPU UUID (nvidia-smi -L) not index, so reordering does not remap cards.
+
+### Concurrency (initial, tunable via *_CONCURRENCY)
+P4 proxy 2 ; L4 proxy 3 ; conform/trim 1 ; P400 thumbnail 2, filmstrip 2.
+
+### Node/GPU attribution (phase 2)
+Stamp each job with node hostname + GPU + tier on start. Mechanism pending
+confirmation of whether Jobs screen reads the jobs DB table or live BullMQ
+(appeared empty during runs): if DB-backed add node/gpu cols (or result jsonb)
+and stamp in createWorker; if BullMQ-backed include node/gpu in job data and
+surface via jobs API. Show "zampp2 / L4" in the Jobs UI row.
+
+## Risks
+- zampp2: heavy NVENC job can contend with an active recording's CPU work
+  (decode/mux uses CPU; GPU itself separate). Mitigate via L4 concurrency and,
+  if needed, pausing heavy intake during active capture.
+- P400 NVENC session caps -> covered by libx264 fallback.
+- zampp2 worker needs reach to zampp1 Redis/Postgres/S3 (already proven for API).
+
+## Verification
+- Enqueue several proxies; nvidia-smi shows encoder util on P4 (zampp1) and L4
+  (zampp2); P400s only on thumbnail/filmstrip.
+- A heavy job never lands on a P400 (worker logs / attribution).
+- Assets still reach ready with proxy+thumbnail+filmstrip.
+- Phase 2: Jobs UI shows correct node/GPU per job.
+
+## Rollout order
+1. GPU tier (WORKER_QUEUES + topology + NVENC) — FIRST.
+2. Node/GPU attribution + Jobs UI.
