The **timing-and-classification** half of a timeout — a zero-dependency library of pure functions (no runtime harness deps) shared by every capability that clamps a caller's timeout hint, arms a deadline, and later has to tell "timed out" apart from "cancelled".
It owns **no termination**. The signal it hands out only *notifies*; actually stopping the work stays in each capability, because that mechanism differs — bash SIGKILLs an OS process group, web tears down a `fetch` socket — and no shared layer can own all of them. This is the boundary the [RFC](../../../docs/rfc/implemented/architecture/2026-07-06-timeout-deadline-library.md) draws: share the timing/classification, keep the hard kill local.

It is a **library, not a service or plugin**: no `ctx`, registers nothing, holds no state, emits no events. A "timeout service" would have to understand how to stop every capability's work — exactly the knowledge a microkernel keeps out of shared layers.

Indirectly, through consumers such as `dsh-timeout-policy`, which may replace a provider result with a retained timeout error or suppress a late result.
#### KV Cache effect
No direct invalidation; the named consumer owns any request-prefix changes.
## Known Limitations and Deferred Work
- **Notification only** — a deadline cannot stop work that ignores its signal; every capability still needs its own socket/process/task termination path.
