Dobromir Popov 2b439e8a5f docs: add US-020–029 issue files, ADR 0011–0014, update prd.json to 29/29
Issue files (.scratch/issues/20-29): retrospective specs for all work
done in the current sprint — hardening, route-timeout, start-layer
protocol, heartbeat stats, availability map, rolling RPM, smart
assignment, throughput routing, routing tests, relay outbound client.

ADRs (docs/adr/0011-0014):
  0011 — Auto-shard from memory budget and tracker network assignment
  0012 — X-Meshnet-Start-Layer overlapping shard execution protocol
  0013 — Rolling RPM statistics, smart assignment scoring, throughput routing
  0014 — Relay outbound client for NAT/internet pipeline hops

prd.json: US-020 through US-029 added, all marked done. ralph_progress.py
now shows 29/29 complete (100%).

US-020 — Tracker + node hardening: BrokenPipe fix, deterministic node IDs, HF coverage

Status: done Priority: High Stage: Maintenance

Context

First two-machine LAN test (US-018) exposed three reliability issues:

  1. BrokenPipeError crash in tracker _send_json when a slow-inference client disconnected mid-response
  2. Random UUID node IDs meant every re-registration (after tracker restart) created a phantom entry
  3. GET /v1/coverage/<model> returned no results when called with a short name (Qwen2.5-0.5B) instead of the full HF repo ID

Acceptance criteria

  • BrokenPipeError in tracker and node _send_json is silently swallowed
  • Node IDs are deterministic: sha256(wallet_address + str(port))[:16]
  • GET /v1/coverage/<model> accepts both short names and full owner/repo IDs
  • python -m pytest passes from repo root
