New state_entry_watch.rs, mirroring disk_watch.rs's shape exactly:
periodic in-process probe, Todos::upsert with a stable count-bucketed
summary (anti-nag - drifting inside one bucket stays silent, crossing
a bucket speaks up again), clears once back under threshold.
Top-level entry count only, deliberately - a large subdirectory (git
clone, build tree) counts as one entry regardless of what's inside it,
which is disk_watch's problem to catch on its own axis (bytes), not
this one's.
Wired into main.rs's spawn_todo_socket alongside disk_watch::run.
closes#3464
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
Part of hyperhive#1898 (b): every docs subdir should have a top-level
README.md link, achieved by moving/renaming where an existing file
already fits the role.
docs/turn-loop.md already served as the hub + index for the three
sub-pages under turn-loop/ (claude-invocation.md, config.md, mcp.md),
so it moves wholesale rather than leaving a redundant top-level
pointer stub. Fixes every inbound/relative link across the repo
(top-level README.md, CLAUDE.md, docs/persistence.md,
docs/tools/scheduling.md, the sub-pages own back-link, hive-agent
README + doc comments, hive-agent/Cargo.toml, .prettierignore per-file
exemption entry) - grepped the whole tree for both turn-loop.md and
turn-loop/ to find every reference rather than trusting a partial
list.
nix fmt clean, cargo check -p hive-agent clean.
Six places in the tree hand-rolled the same connect / write one JSON
line / read one JSON line back. Two of them — the harness serve loop's
client and the MCP server's — were byte-identical apart from a six-line
wrapper, ~145 lines of literal copy-paste. The other four each
reimplemented a subset, and the subsets had drifted: some named the
socket path in their errors and some did not, one classified transient
against fatal failures and the rest retried nothing at all, two drained
the response and two decoded it.
That duplication was defended when the daemons were split out, on the
grounds that a daemon's socket etiquette should stay visible in the
crate that depends on it. The etiquette genuinely does differ. The code
does not, and five copies is where "each daemon documents its own
etiquette" stops paying for itself.
`hive-sock-client` now owns the transport once, generic over the
request and response types so it is protocol-agnostic: the host-served
control socket and the harness's in-agent socket both use it with their
own wire-type crates. The two real differences become values instead of
forks. Retry is `Retry::RideOutRestart` (2/4/8/16/30s, sized to ride out
a service restart) for callers with no natural retry of their own, or
`Retry::None` for callers already inside a poll loop where the poll
interval is the retry — and the reason each caller picked one is a
comment at the call site rather than a reimplementation. The response is
either decoded (`request`) or half-closed and drained (`notify`, where
the drain exists so the server's write-back doesn't land on a closed
socket). Whether a failure propagates or is logged and swallowed stays
at the call site, because that is the caller's choice and not a property
of the transport.
Errors always name the socket path now, everywhere. That detail is
load-bearing: a permission problem on a socket that reads as "is the
daemon running?" sends the operator to fix the wrong thing.
The transient-against-fatal enum is gone rather than moved. Serialising
happens before the retry loop and deserialising after it, so only
connect, I/O and short-read failures can reach the loop at all — a
deterministic failure is now unretryable by construction instead of by
classification.
It is deliberately a new crate and not part of `hive-agent-sock`. The
`*-sock` crates are pure wire types by convention — `hive-agent-sock`
depends on serde and nothing else — and the two largest copies talk to
the host socket, whose types live in a different crate entirely. A
transport in either wire-type crate would drag tokio into it and point
the wrong way besides.
No wire-format change: same JSON line in, same line out.
The poller was a `tokio::spawn` inside the `hive-agent` serve loop. It
never needed anything from that loop except a socket path, so being
in-process bought nothing and cost two things: a harness restart took
forge notifications down with it, and the whole forge/HTTP dependency
tree was linked into the serve-loop binary.
It is now `hive-forge-notify`, a per-agent daemon with its own systemd
unit, a sibling of `hive-bash-daemon` and `hive-matrix-daemon`. Same
contract as those two: it reaches the harness only by upserting todos on
the in-agent socket, and nowhere else.
The module moves verbatim (`notify.rs`) — the formatters, the activation
gates, the dedupe map and all 33 tests are unchanged. Only the socket
call sites are rewritten, onto a small local `todo_client` rather than
the harness's. That mirrors what both sibling daemons already do, and
the etiquette differs on purpose: the harness's client carries a 60s
backoff schedule sized to ride out a hive-c0re restart, which its
callers need because they have no retry of their own. This poller's two
call sites both sit inside the 30s poll loop and both treat a failure as
"leave the thread unread, try next tick", so the poll interval already
is the retry; a second backoff would only stack sleeps and delay the
rest of the batch.
The unit is `Restart=on-failure`, not `always`. An agent with no forge
account is a supported configuration and the poller reports it by
logging why and exiting 0 — under `always` that clean exit would be a
restart loop on every forge-less agent.
`forgejo-api`, `url` and `time` drop out of `hive-agent`'s dependencies
with the module.
Also corrects docs that outlived the code they described: the persisted
`forge_cursor` field is long gone (forge's own read-state is the durable
record of what has been delivered), but `docs/persistence.md` and the
`harness_state` module docs still documented it as live.
Closes 2718.
The operator has been going through agent dirs by hand with ncdu,
deleting 20+GB target dirs. Agents had no way to know they were the
ones sitting on the space.
New `disk_watch` module in the harness: every 15 minutes it statvfs's
the filesystem backing the agent's state dir and, past 80%, raises a
keyed `disk` todo telling the agent to free space — with the operator's
rules inline: only delete things that are actually big, build output
first, and never delete something still needed, ask for more space
instead.
Over threshold it also walks the agent's own tree (`/agents/<label>`
plus `$HOME`) and names the directories worth looking at, so the todo
says where the bytes actually went rather than just that the disk is
full. The walk is bounded on every axis — entry budget, recursion cap,
report depth — pinned to the state dir's device so it can't wander into
`/nix` or the shared bind mounts, and it does not traverse symlinks. It
reports the deepest oversized directory on each branch, so the agent
gets pointed at `<workspace>/target` rather than at `/agents/<label>`.
Anti-nag is the whole design constraint. The todo is keyed, and the
summary is deliberately stable: the percentage is bucketed to 5 points
and no raw byte counts appear anywhere in it. An unchanged situation
re-upserts as `changed == false` and never fires the wake, so a disk
that has been steady at 89% for a week sits quietly in the loose-ends
list; crossing into a new bucket speaks up once. Dropping back under
the threshold clears the row.
Harness-local by construction, per the operator's call that this gets
no core wiring: hive-c0re cannot push a todo at all (the store and its
wake live inside the container), and running in-process means this
skips even the in-agent socket and calls `Todos::upsert` directly.
Worth recording, since it shaped the scope: btrfs does NOT fold qgroup
limits into statfs. Measured with quota counting enabled and a 20G
limit set on a real subvolume, statvfs returns byte-identical whole-FS
numbers for that subvolume, an ordinary agent dir, and the root. So
this watches host-FS pressure, which is valid before and after the
planned subvolume migration; per-agent quota awareness would need the
limit handed to the agent explicitly.
A paused agent keeps its container, its claude session and its
dashboard/todo servers up, but stops driving turns. Messages queue
unacked and are drained on resume.
The whole protocol is a single marker file, `<harness>/paused`. That
directory is already a bind-mount shared between host and container, so
both sides just stat the same path: the harness reads it to decide
whether to drive a turn, hive-c0re reads it to render the badge and
writes/removes it for `hivectl pause|resume`. No new wire protocol, no
container round-trip, and it is sticky across restarts by construction.
Not calling `recv_next` while paused *is* the queueing semantic, so
there is no fencing to get wrong: reminders buffer in their unbounded
channel, the todo `Notify` permit coalesces, and a `request_next_turn`
that raced the pause survives because the gate sits above
`self_continue.take()`.
Graceful stop is handled host-side rather than in the harness: a paused
agent provably has no turn in flight, so `run_signal` skips the fence
entirely instead of eating the full `GRACEFUL_STOP_TIMEOUT` waiting for
a checkpoint turn that will never run.
`paused` is reported on `ContainerView` / `AgentStatusRow` for the
dashboard, orthogonal to `running` and reported for stopped containers
too.

diagnostic instrumentation for #2678 (phantom 'you have todos' wakes
after clearing bash-task todos). logs subsystem/key/id/changed on
UpsertTodo, subsystem/key/all/count on ClearTodo, id/count on
MarkTodoDone, and a marker when the serve loop actually consumes a
todo_wake notification. no behavior change - RUST_LOG=debug only.
Move per-message rendering logic from frontend JS to backend Rust.
A new stream_enrich::enrich() function stamps display fields onto
LiveEvent::Stream payloads at SSE-emit time (both live tail and history
replay), so the frontend can consume pre-computed fields instead of
re-implementing the dispatch logic in JavaScript.
Phase 1: backend stamps _icon/_summary/_category; client falls back to
its own JS tables when absent. Zero user-visible change.
- system events: _category (drop/thinking_tok/note/details) + _summary
and optional _body (commands_changed expands to a slash-cmd list)
- assistant tool_use entries: _icon + _summary per tool; rich tools
(Write, Edit, send, ask, answer) get _category: 'rich'
- enrichment applied in web_ui/stream.rs at emit time; DB stores raw
events so no migration is needed when enrichment logic changes
- idempotent: existing _-prefixed fields are left unchanged
