v1.0.0 — Groundwork (Londonmaxxing 003 final build)

Groundwork — the final Londonmaxxing 003 hackathon build, frozen at the end of the hack day (4 Jul 2026, commit 01d2c95). Development continued afterwards on main.

One AG-UI/A2UI workflow engine on a single Cloudflare Worker: POST /run?usecase=<id> drives a runStages loop (plan → tool → render) and the agent streams A2UI cards — it paints the interface, not just text. Two interchangeable London workflows behind one ?usecase= switch.

▶ Live demo: https://qte77.github.io/ldnmxx-hack/ · Worker API: https://ldnmxx-hack-worker.cloudflare-driveway392.workers.dev

Shipped in v1.0.0

• Phase-1 E2E: SPA → POST /run?usecase=<id> (SSE) → built-in A2UI cards; useAgentSSE transport; runStages per usecase (founders-copilot + thin on-it); console Arize span per stage; optional in-dashboard BYOK; ui/worker CI + GitHub Pages deploy (#16, #17).
• Track B search_opportunities render via a real OpenRouter model, with a deterministic stub fallback (#19); raised max_tokens so render_ui isn't truncated (#22).
• Theme toggle + ?demo=1 keyless auto-run (#20); live A2UI component catalog + Track-A default + 100% worker observability (#24); usecase toggle swaps the example query (#25).
