All functional renames (MANAGER_NAME, MANAGER_AGENT → "root") were done in earlier commits. This cleans up the stale `hm1nd` strings that remained in doc comments, test fixture labels, and the manager MCP server instructions (which told the manager its config lived at /agents/hm1nd/config/agent.nix).

//! Per-agent path resolution for state, harness, and credential directories.
|
|
//!
|
|
//! All agents (including the manager `root`) use `/agents/{label}/state`
|
|
//! for agent-owned durable notes, and `/agents/{label}/harness` for
|
|
//! harness-internal files (`hyperhive-events.sqlite`, `hyperhive-model`, etc.)
|
|
//! that should not clutter what claude sees as "my notes dir".
|
|
//! Claude credentials live at `$HOME/.claude` (resolves to
|
|
//! `/home/<agent-name>/.claude` because the harness service runs as a
|
|
//! non-root unix user matching the agent label — see
|
|
//! `docs/persistence.md::First-boot agent-user migration`).
|
|
//!
|
|
//! All three paths can be overridden via env vars (`HYPERHIVE_STATE_DIR`,
|
|
//! `HYPERHIVE_HARNESS_DIR`, `HYPERHIVE_CLAUDE_DIR`) for dev / test scenarios.
