atlas d2747c7b77 refs: repoint seven comments that name files which have moved 
Comments cite nix modules, scripts and crate source files constantly,
and nothing evaluates a comment — so when a file moves, the reference
rots silently and `nix flake check` stays green. A reader following one
finds nothing and cannot tell whether the file was renamed, deleted, or
never existed.

Seven such references, each repointed at the file that actually holds
the thing the sentence is about rather than at the directory the old
name became:

  hive-c0re/src/agent_config/limits.rs   hive-agent/src/mcp.rs
                                       -> hive-agent-mcp/src/mcp/mod.rs
  hive-agent-mcp/src/mcp/mod.rs          hive-c0re/src/limits.rs
                                       -> hive-c0re/src/agent_config/limits.rs
                                         (and the module path in the doc
                                          comment above it, which was stale
                                          in the same way)
  hive-c0re/src/forge/mod.rs             hive-c0re/src/knowledge.rs
                                       -> hive-c0re/src/workers/knowledge.rs
  nix/host-modules/hive-c0re/options.nix hive-c0re/src/hive_stats.rs
                                       -> hive-c0re/src/stats/hive_stats.rs
  nix/packages/default.nix               nix/host-modules/hive-c0re.nix
                                       -> .../hive-c0re/options.nix
  nix/agent-modules/network.nix          nix/host-modules/hive-gateway.nix
                                       -> .../hive-gateway/dnsmasq.nix
  frontend/README.md                     nix/modules/frontend.nix
                                       -> nix/packages/frontend.nix

The two `limits.rs` comments are a matched pair: each names the other's
old path, so the "keep in sync" instruction they exist to carry pointed
both ways at nothing.

Where a flat module became a directory the target is the file that
declares the named thing, not `default.nix` by reflex — the
`preBuildAgentTemplates` option is declared in `options.nix`, and the
DHCP pool that sentence is about lives in `dnsmasq.nix`.

Comments only; no behaviour change. Refs #3923, which is about whether a
gate should cover this class at all — that question is unanswered and
this does not close it.

hive-agent-mcp

The built-in hyperhive MCP server every agent gets by default. Runs a long-lived streamable-http listener (the hive-mcp-http systemd unit) that claude reconnects to each turn via --mcp-config — this avoids the per-turn stdio re-registration race that a spawned-per-turn server would hit. HTTP is the sole transport; there is no stdio mode here.

When to use it

This is where the core hyperhive tool surface lives: send, recv, remind, get_loose_ends, set_status, get_agent_meta, lifecycle (kill/start/restart/update on direct children), scheduling, and the approval-request tools. Reach for this crate when you're adding or changing a built-in tool rather than an extraMcpServers add-on — those are separate stdio bridges (see hive-bash-mcp, hive-matrix-mcp) that dial the harness socket or their own daemon instead of living here.

Shape

  • mcp/ — the tool surface itself: one handler per tool, dispatch through client.rs back into the hyperhive broker (/run/hive/mcp.sock) or, for loose-ends v2 (todos/reminders), the in-agent socket the hive-agent harness serves.
  • client.rs — socket client to the hyperhive broker.
  • send_allow.rs — enforces the per-agent hyperhive.allowedRecipients allow-list on send.
  • paths.rs — socket + state path resolution shared with the harness's own paths.rs conventions.

Sibling of hive-agent (the serve loop that renders the --mcp-config blob pointing here). Standalone bin crate so the always-on MCP server doesn't need to link the whole turn-loop lib.
