# hive-forge-notify

Per-agent Forgejo notification poller: a long-running daemon
(`hive-forge-notify`) that watches the agent's unread notification list
and turns each thread into a todo the harness surfaces in
`get_loose_ends`. This is why an agent wakes up when someone comments
on its issue or requests its review.

## When to use it

Look here when changing what a forge notification *says* when it
reaches an agent, or when it reaches one at all: the poll cadence, the
self-echo filter, the comment / review / new-item / state-change
wrapper formats, body-excerpt truncation, and the assigned-issue
rollup all live in `notify.rs`. The behaviour contract — activation
gates, filtering rules, the review-request override — is documented in
[`docs/forge.md`](../docs/forge.md), "Notification poller".

## Shape

One bin, three modules:

- **`main.rs`** — argument-free entry point. Reads `HIVE_AGENT_SOCKET`,
  initialises tracing, hands off to `notify::run`.
- **`notify.rs`** — the poller: forge client setup, the 30s loop, the
  formatters, mark-read, and the in-process delivery-dedupe map.
- **`todo_client.rs`** — one-shot JSON-line client for the harness's
  in-agent socket. No retry schedule of its own; see the module doc.

## Why it is a separate process

It used to be a `tokio::spawn` inside the `hive-agent` serve loop. It
never needed anything from the serve loop except a socket path, and
running it in-process meant a harness restart also took forge
notifications down, and linked the whole forge/HTTP dependency tree
(`forgejo-api`, `reqwest`, `time`, `url`) into the serve-loop binary.
It is now a sibling daemon alongside `hive-bash-daemon` and
`hive-matrix-daemon`, with the same contract: it talks to the harness
over the in-agent todo socket and nowhere else.

Forge's own read-state is the durable, cross-rebuild record of what has
been delivered — there is no persisted cursor to migrate or corrupt. A
restarted poller re-scans only the genuinely-still-unread set, which is
tiny by construction because delivery marks the thread read.
