cosign-demo

Update the repo’s contributor-facing docs when architecture, runtime setup, or workflow changes land.

Audit the root README for discoverability, reading order, and contributor usefulness.

Extract one bounded feature from the monolith into an explicit slice without mixing multiple domains into one move.

Define deterministic mock fixtures and scenario coverage for contributor-friendly local development and tests.

Safely change a proposal or session payload contract across client, server, and protocol boundaries.

Validate the standalone demo before a preview or release handoff.

Trace a room, proposal, checkout, or wallet flow end-to-end across UI, API, and Yellow SDK boundaries before editing it.

Debug deposits, withdrawals, quick approvals, and channel/session mismatches without guessing at protocol state.
