ci/woodpecker/push/main-amd64-build Pipeline was successful
- Group docs by category with an index (docs/README.md); fix every link, code comment and the protocol conformance test that read docs/protocol.md. - access.md and security.md rewritten to what is implemented: removed the unadopted member-proof chain, roles and recovery key that do not exist, the old implementation order and the budgets; gaps now carry a status. - enrollment, deployment, api: the install flow is the static, hash-checked script with environment variables; no default admin. - README and architecture: new topology and update-flow diagrams (operator passkey, CI signing, registry feed, auth and trust modules).
