Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# grove.core.watches — register a callback, halt, and be woken

> ↑ [grove.core](../CLAUDE.md) · [root](../../../../CLAUDE.md)

One concern: an agent waiting on something slow says what it is waiting for and **stops**, and Grove delivers the outcome when it settles. Wire shapes live in [contracts/watches.py](../contracts/CLAUDE.md); delivery is [`core/mailboxes.py`](../CLAUDE.md) unchanged; the daemon owns the routes and the lifespan.

## The cost model IS the design

A naive implementation gives each waiter a thread, or wakes every few seconds and scans the registry. Both scale CPU with how many agents happen to be waiting, which on a fleet host is exactly backwards — **waiting should be free**.

- **One scheduler for the host**: a single asyncio task over a `heapq` keyed on `next_due`, plus one `asyncio.Event` that register/cancel set to wake it early. No thread, process, timer or sleeping coroutine per watch or per workspace.
- **Nothing periodic.** An empty registry returns `None` from `seconds_until_next()`, so the loop awaits an event rather than a clock and no timer exists to fire. There is no tick, no sweep, no scan — the heap's minimum IS the next wakeup.

How to install

The exact contents, by fingerprint

mdr add bearlike/grove/src/grove/core/watches/CLAUDE.md@sha256:7dd6b6556bac65ef

The line at the top of this page pins the label git:20261002.ab7241f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
