atlas eaca3c4eb3 agents: always write the memory cap, infinity for none 
The cap file was removed for a cap of `infinity` or a RAM percentage,
so the boot check warned on every start of such an agent, for a
legitimate config. The file is now written on every start:

- a size: its byte count, as before;
- `infinity`: the literal `infinity`. The generators set no JSC heap
  ceiling and no subagent MemoryHigh=, and the boot check is quiet;
- a percentage: resolved on the host the way systemd resolves
  MemoryMax=N% for the container@ unit. That is permyriad (at most two
  decimals, at most 100%) of sysconf(_SC_PHYS_PAGES) *
  sysconf(_SC_PAGESIZE), rounded down to a page;
- a value systemd ignores (zero, over 100%, more than two decimals,
  unparseable) leaves the unit uncapped, so it is `infinity`.

The file is missing only when hive-c0re can't tell the cap: the
limits file and the kept drop-in are both unreadable, or a percentage
meets an unknown host memory size. The boot check now warns only for
a missing file or a first line that is neither a byte count nor
`infinity`.

Part of #5081 (slice S0-2).

hive-c0re

The unprivileged host daemon (runs as hive-core). Owns the sqlite broker, the reminder queue, the generic job-DAG queue, container lifecycle, gateway vhost wiring, forge/matrix config reconciliation, per-container stats, and the axum operator dashboard. Largest crate in the workspace — bin-only, no separate lib.

When to use it

Host-level, cross-container orchestration: spawning/rebuilding/ destroying agent containers, dashboard-visible state, wiring each agent's gateway vhost and reconciling its forge config-repo access and matrix room membership. The accounts themselves are swarm-controller's (docs/integrations/forge.md). Agent-side behavior (turn loop, MCP tools) lives in hive-agent/hive-agent-mcp instead — this daemon only talks to agents over the socket wire types in hive-sh4re.

Shape

Cohesive clusters live in directory submodules, each re-exported at the crate root (crate::broker::… keeps resolving regardless of which subdirectory a module actually lives in). One line each — read the module's own //! doc-comment for real detail, don't expect this file to track it:

  • dashboard/ — the operator dashboard (containers, schedules, logs, topology).
  • job_queue/ — the job-DAG queue + desired-state reconciliation (docs/scheduler/coordinator.md).
  • lifecycle/ — nixos-container lifecycle + per-agent config flake generation.
  • stores/ — sqlite-backed stores (broker, queues, audit, power).
  • workers/ — background sweeps (crash watch, autoupdate, knowledge sync).
  • agent_config/ — per-agent registries (tool groups, capabilities, resource limits, topology).
  • stats/ — dashboard metrics aggregation + OTEL export.
  • socket_server/ — the unix-socket request server shared by per-agent + manager sockets.
  • forge/ — optional Forgejo wiring (docs/integrations/forge.md).
  • coordinator.rs — top-level wiring for serve.
  • meta.rs, migrate.rs — the meta flake + schema/state migrations.
  • matrix.rs, gateway_nginx.rs, priv_client.rs — matrix provisioning, gateway vhosts, and the hive-priv client respectively.
