Agent (P2.1): Agent struct with registry DB, runtime, and logger.
gRPC server with TLS 1.3 and MCIAS auth interceptor. Graceful
shutdown on SIGINT/SIGTERM. All RPCs return Unimplemented until
handlers are built in P2.2-P2.9.
CLI (P3.1): Full command tree with all 15 subcommands as stubs
(login, deploy, stop, start, restart, list, ps, status, sync,
adopt, service show/edit/export, push, pull, node list/add/remove).
gRPC dial helper with TLS, CA cert, and bearer token attachment.
Both gates for parallel Phase 2+3 work are now open.

Go module, Makefile with standard targets, golangci-lint v2 config,
CLAUDE.md, and empty CLI/agent binaries. Build, vet, and lint all pass.

30 discrete tasks across 5 phases, with dependency graph and
parallelism analysis. Phase 1 (5 core libraries) is fully parallel.
Phases 2+3+4 (agent handlers, CLI commands, deployment artifacts)
support up to 8+ concurrent engineers/agents. Critical path is
proto → registry + runtime → agent deploy → integration tests.

Incorporates all 14 items from DESIGN_AUDIT.md: node registry in CLI
config, container naming convention (<service>-<component>), active
state semantics, adopt by service prefix, EventInfo service field,
version from image tag, snapshot/backup timer, exec-style alert
commands, overlay-only bind address, RPC audit logging, /srv/ ownership,
rootless podman UID mapping docs.
Three minor fixes from final review: stale adopt syntax in bootstrap
section, explicit container naming in deploy flow, clarify that list/ps
query all registered nodes.

Engineering and security review of the rewritten ARCHITECTURE.md.
14 issues identified and resolved: node registry in CLI config,
active/desired_state semantics, container naming convention
(<service>-<component>), exec-style alert commands to prevent
injection, agent binds to overlay IP only (not behind MC-Proxy),
RPC audit logging, /srv/ owned by mcp user, and others.

Major design changes from the review:
- Merge agent and watcher into a single smart per-node daemon
- CLI is a thin client with no database; service definition files
are the operator's source of truth for desired state
- Registry database lives on the agent, not the CLI
- Rename containers to components; components are independently
deployable within a service (mcp deploy metacrypt/web)
- active: true/false in service definitions; desired_state values
are running/stopped/ignore
- Server-side TLS + bearer token (not mTLS)
- Dedicated mcp user with rootless podman
- CLI commands: list (registry), ps (live), status (drift+events),
sync (push desired state)
- Agent reports node resources (disk, memory, CPU) for future scheduling
- Agent is gRPC-only (deliberate exception to REST+gRPC parity rule)

Documents 12 issues found during critical review of ARCHITECTURE.md
and their resolutions: merged agent/watcher into single smart daemon,
components model for independent deploy within services, database
lives on agent not CLI, TLS+bearer (not mTLS), desired_state=ignore
for unmanaged containers, and other clarifications.

Design spec for the Metacircular Control Plane covering master/agent
architecture, service registry with desired/observed state tracking,
container lifecycle management, service definition files, single-file
transfer scoped to /srv/<service>/, and continuous monitoring via
mcp watch with event logging and alerting.
