Replace Probe with Agent across node runtime, Fleet contracts, backend state, API and storage. Report incoming sessions and outgoing link health through each Agent uplink, and retain directed link controls and retry.
Update protocol fixtures and end-to-end coverage for the unified model; accept requested cancellation during the Fleet timeout test cleanup.
- Remove the node capability paragraph from README; soften "pure collector"
and "no self-update" statements in docs, AGENTS.md and READMEs
- architecture.md: drop scalability goals, design decisions and open items;
add a component-to-code table and code links
- Replace rhetorical contrasts in security docs with direct statements
- AGENTS.md: add project mental model, change map and writing style rules
- 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).
Methods, roles and binary channels are declared in one table per plane (node and peer). RpcRouter checks direction, kind and role when handlers are registered, when messages arrive (fleet_protocol_violation, disconnect after repeated violations) and before sending. NodeConnection is split by responsibility.
