Record the cross-repo documentation fixes, registry-landing removal, and the
Start9 submission blockers. A plain GET to registry.keysat.xyz 404s by design
(StartOS registry protocol only), not an outage.
Current state: the onboarding doc-harness and its Stage 1 completed-clean
result. ROADMAP: spell out Stage 2 (regtest buyer-pays) under the
agent-payment-connect item. Drop the resolved GET /v1/admin/products 405
debt item.
Agent-onboarding doc for the workspace: stack, build/test/run commands,
directory layout, conventions, and always/never gotchas, plus a Current
state section. CLAUDE.md symlinks to AGENTS.md so Claude Code auto-loads
it. Longer-term backlog lives in ROADMAP.md.
