- cli.py: change default --quantization from bfloat16 to int8; saves
~50% VRAM/RAM for new nodes that don't specify a quantization
- startup.py: display memory budget and GPU info in GB (e.g. 124.9 GB RAM)
instead of MB; show remaining headroom after full model load
- test_tracker_routing.py: add test_shard_heal_cycle_surviving_node_covers_dead_peers_gap
— end-to-end proof that:
1. tracker purges expired node A and queues LOAD_SHARD for node B
2. node B receives directive on next heartbeat
3. TorchNodeServer.apply_tracker_directives hot-swaps the backend
4. node B re-registers covering the full model; coverage gap closed
Test runs in <1s with monkeypatched _load_backend (no GPU needed)

_select_route now prefers nodes with higher effective throughput
(benchmark_tokens_per_sec / (queue_depth + 1)) when multiple nodes
cover the same interval, breaking the tie after max-reach selection.
TorchNodeServer.route_timeout property added for external inspection.
Tests added:
- _select_route with overlapping shards (A:0-22, B:20-24) → correct X-Meshnet-Start-Layer protocol
- _select_route with gap → clear error message
- Fast node beats slow node when shards are equal
- Busy fast node vs idle slow node (queue_depth factor)
- Two-StubNodeServer integration via TrackerServer
- route_timeout property exposed on TorchNodeServer

Adds _RollingCounter and _StatsCollector to the tracker: three rolling windows
(hour=60×1min, day=24×1hr, month=30×1day) track request RPMs per model.
GET /v1/stats returns combined local + peer stats. POST /v1/stats/gossip lets
trackers push their local slice for additive merge in hive mode.
SQLite persistence via --stats-db flag; stats survive tracker restarts.
Records a stat for each proxied /v1/chat/completions request.

Coverage endpoint now skips node purge so dead nodes remain visible.
Each band in /v1/coverage/<model> includes a `nodes` array with per-node
health: alive status, last_seen_seconds_ago, heartbeat_success_rate,
inference_success_rate, queue_depth, uptime_seconds, and endpoint.
Updated tests to assert new band structure.

- Wrap wfile.write in _TrackerHandler._send_json with except BrokenPipeError
- Replace uuid4 node IDs with deterministic SHA-256 hash of endpoint+model+shards
so nodes keep the same ID on re-registration after tracker restart
- /v1/models now lists HF-repo models (not just preset models)
- /v1/coverage/{model} now resolves HF repos, not just preset names
- /v1/route response includes node_id alongside endpoint
- startup.py exposes tracker_node_id on node object and prints it in dashboard

Recovered from interrupted Codex session (ended 13:02, changes uncommitted).
All 74 tests pass.
- Tracker accepts vram_bytes, ram_bytes, quantizations[], benchmark_tokens_per_sec
in node registration payload
- GET /v1/coverage/<model_preset> returns [{start_layer, end_layer, node_count}]
- Coverage-first bin-packing: fills gaps before adding redundancy
- Speed-weighted assignment: faster nodes get wider shard ranges
- LOAD_SHARD/DROP_SHARD rebalance directives delivered via heartbeat responses
- Model is unroutable when any layer range has node_count=0
- model_presets.json config for bytes_per_layer at each quantization level
