atlas be3411e180 feat(#3245): gate rustdoc in nix flake check, and clear the workspace
Nothing in the gate read doc-comments: clippy doesn't check intra-doc
links, cargo test doesn't, and no check built docs. So a [`Foo`] pointing
at a renamed, moved or deleted item rendered as plain text and had no
discoverer but a human happening to read the comment.

That matters here more than in most repos, because the convention is to
put a thing's authoritative description in one doc-comment and point at
it from everywhere else -- the design leans on the pointers being real,
and a dangling link is worse than no link since it names something and
sends the reader looking.

Adds `docs-rustdoc` to nix/checks.nix: craneLib.cargoDoc over
--workspace --no-deps --document-private-items, denying six rustdoc
lints. Listed explicitly rather than -D warnings so a new lint appearing
upstream cannot red the build on a class nobody has triaged.

--document-private-items is load-bearing rather than thoroughness for
its own sake: most of this workspace's doc-comments live on private
items and //! module headers, so without it rustdoc checks a small
fraction of the links and the gate sits green while the rot continues.

Then fixes every error it reports, 40 to 0 across nine crates. The
classes differ and so do the fixes:

- public item, wrong scope -> qualify. Node and Node::parent are both
  public; the link failed only because scheduler.rs does not import
  Node. Six sites become [`crate::Node::parent`].
- private item -> downgrade to backticks. Nothing was made public to
  satisfy a lint; changing API surface to appease a doc check would be
  the tail wagging the dog.
- genuinely dead -> [`JobBuilder::insert_into`] names a method that does
  not exist. Insertion is Scheduler::insert_job.
- prose that looks like markup -> argv[0] parsed as a link, and
  <args>/<hex>/<name> parsed as HTML tags.

Note for future fixes: pub(crate) resolves in an intra-doc link, a plain
private fn in a binary crate does not (wait_for_nodes resolved,
connect_hint did not, same crate, same shape).

The check does not ride the clippy/test artifact cache. It takes
cargoArtifacts, but rustdoc needs its own flavour of dependency
metadata, which cargo build does not produce, so a --no-deps docs build
still compiles dependencies it never documents. Measured at 6m47s cold;
that reasoning is recorded in the check's own comment so the next reader
does not re-derive it.

Verified by running the check's exact command against the pre-cleanup
tree first: 40 errors, build failed. A gate that cannot fail is not
evidence, and building it before the cleanup makes that proof free.

hive-bash-mcp

Per-agent background bash-task runner: a long-running daemon (hive-bash-daemon) plus the thin stdio MCP bridge (hive-bash-mcp) claude spawns each turn to talk to it. This is what backs the bash_run / bash_status tools agents use to kick off long-lived shell commands (builds, test suites, anything that shouldn't block a turn) and check on them later.

When to use it

Look here when changing how background bash tasks are spawned, tracked, or surfaced. The daemon owns all subprocess lifecycle (sh -c spawn, completion monitoring, task state files under harness/bash-tasks/) and pushes task-completion todos onto the harness's in-agent socket so they show up in get_loose_ends. The bridge binary is deliberately dumb: no subprocess management, just a unix-socket round-trip per tool call, so it cold-starts in milliseconds every turn.

Shape

Two bins from one shared lib (src/lib.rs):

  • hive-bash-daemon (src/main.rs) — the long-running daemon. runner.rs is the spawn/monitor loop and pushes todos on task transitions; socket.rs serves the daemon's own unix socket for tool-call requests from the bridge.
  • hive-bash-mcp (src/bin/mcp.rs) — the stdio MCP server claude spawns per turn. Forwards every tool call to the daemon over the socket via protocol.rs's DaemonRequest/DaemonResponse and returns the result.

Supporting modules: paths.rs (daemon socket + agent-socket resolution), stats.rs (the bash_commands favorite-tool stat recorded into turn-stats.sqlite).
