# Cordis Events Catalog

Every cordis event a plugin can listen to: exact signature, dispatch mode, and original declaration JSDoc. This is one axis of the **wiring** reference a plugin author works against — the callable `ctx.<key>` surface is the sibling [services catalog](services.md), and [core-data-structures/](../core-data-structures/core.md) catalogs the *data structures* these signatures move around.

This file is GENERATED from source (`scripts/gen-cordis-catalog.ts`) and verified fresh by `pnpm run verify-cordis-catalog` (part of `doc-sync`) — do not edit it by hand. Signature blocks use a `ts cordis-catalog` fence and include the original source JSDoc immediately before each event or service method. doc-typecheck skips these bare declaration fragments; type names in a signature link to the page that documents them.

The **harness tier** below (the `@deepseek-ai/dsh-*` packages) is the vocabulary this repo owns, grouped by scope. The **inherited tier** at the end is the cordis-core + loader/hmr/timer event surface a plugin also sees — pinned vendor source, summarized tersely. The event-dispatch methods themselves are generated in the [Cordis core Events API](core/events.md).

Dispatch modes: **emit** (fire-and-forget), **waterfall** (each listener gets `next()` and may transform or veto — see [waterfall semantics](../cordis-primer.md#cordis-waterfall-semantics)), **parallel** (awaited fan-out; all listeners run), **serial** (awaited in registration order until one returns a bail value — anything other than `null`, `false`, or `undefined`), **bail** (synchronous in-order dispatch until one listener returns a bail value; the scoped input-mutation events use it for an applied/not-applied answer).

## `agent/*`

### `agent/cancel-requested` — emit

Effective broad cancellation was requested, before queued/outbox work is cleared or the active turn is aborted. This observe-only notification cannot veto cancellation; listener failures are contained.

```ts cordis-catalog

### `agent/created` — emit

A fully configured agent and live session were published. Setup is composition-only; `agent/session-start` is the first startup-driving seam. Synchronous listener failure vetoes publication, while returned-promise rejection is reported. Detach requested during dispatch waits until every creation listener has observed the stable entry.

An agent left the registry; AgentLoop emits this after driver quiescence and scoped-registration unwind, but before session detachment. Custom registry users own their driver-ordering contract.

```ts cordis-catalog

### `agent/inbox/discard` — emit

Pending inbox items were dropped without delivering them, so every enqueue occurrence receives exactly one terminal `agent/inbox/dequeue` OR `agent/inbox/discard`. `cancel()` without `keepInbox`, including disposal, emits this after `agent/cancel-requested` when applicable and before aborting the active work.

### `agent/prompt-submit` — waterfall

Allow, rewrite, or block one claimed prompt before it becomes a user message or opens a turn. Call `next()` for the unchanged default. The signal controls only this admission attempt; listeners may cooperate with it but must not retain it for a later attempt or turn.

### `agent/request` — waterfall

Replace the frozen call configuration. `await next()` yields the config the machine would use (agent options on the first request, the logged header afterwards); return a replacement to switch. Model-visible content must use logged channels; this seam cannot mutate messages.

### `agent/request-error` — waterfall

Handle a model-request failure after its failed step has closed but before the failed turn closes. A listener returns `{ kind: 'retry' }` without calling `next()` when it owns the error, or calls `next()` to delegate. The default `undefined` leaves the failure terminal.

One drain chain reached its terminal turn: that turn's `turn/end` is already committed. Automatically recovered failed turns do not emit this notification, and neither does a run that aborts or fails before its `turn/start` commits — there is no durable turn to settle against. `reason` says why; model-request recovery is exhausted when an error reaches it.

### `agent/step` — serial

Awaited serial checkpoint before EVERY request of a turn is built (the first as well as each post-tools continuation). The single "between steps" extension point: inject context, steer, or edit the session log here — the request's history derives from the log right after this settles.

### `agent/turn-stopping` — serial

The turn is about to close: the model owes no response (no live tool calls, no fresh steering). Awaited before the boundary commits — a listener that objects steers (`agent.steer(...)`) and the machine re-reads its inbox: fresh steering runs another step, none closes the turn. Data decides, so listener order cannot change the outcome. The inverse control (stop a tool loop early) is data too: a tool result carrying `concludesTurn` ends the turn at its step.

A returned-promise rejection is logged but cannot retroactively veto this synchronous boundary. Scope-filtered dispatch (`@deepseek-ai/dsh-scope`): agent-scoped listeners receive only sessions entered through that agent's context.

```ts cordis-catalog

## `telemetry/*`

### `telemetry/record` — waterfall

Transform one outbound record before it reaches the backend. This waterfall is the seam's redaction extension point. It ships NO rules of its own: the innermost `next()` passes the record through unchanged, and with no listener mounted records reach the backend as captured, so exported data is exactly as clean as the rules a deployment mounts. Listeners stack by transforming `next()`'s return value; returning without `next()` replaces everything beneath. Dispatched synchronously on the capture hot path inside the coordinator's containment: a throwing listener withholds that one record (fail-closed) and never reaches the agent loop. Redaction applies to the exported copy only; the canonical session log is never rewritten.

### `tools/code-dispatch-log` — waterfall

Shape the DURABLE LOG COPY of one `run_code` sub-dispatch outcome before the bridge appends its `tool/code-dispatch` event. `next()` keeps the content unchanged; a listener may return replacement blocks (e.g. the spill policy's preview + locator for an oversized text result). Only the logged copy is affected — the program already received the complete value, and the model sees neither. A throwing listener is contained: the bridge falls back to logging the unshaped content. Scope-filtered dispatch (`@deepseek-ai/dsh-scope`): agent-scoped listeners receive only that agent's dispatches.

### `tools/execute` — waterfall

Around-dispatch waterfall for timeout, retry, or metrics. `next()` returns a normalized result; wrappers may change only `exec.signal`, while call identity remains immutable. The registry re-fuses the original caller signal before the body, so replacement cannot detach caller cancellation; wrappers must still restore their signal and reach quiescence.

## Inherited events (cordis core + loader/hmr/timer)

The framework events every plugin also sees, beyond the harness vocabulary above. This is pinned vendor source ([vendoring policy](../../vendor/README.md)); it is summarized here so the page is a complete picture of the event bus, without elevating framework internals to the harness tier's prominence.

- `internal/listener` — A listener was registered. ([`vendor/cordis/src/events.ts:340`](../../vendor/cordis/src/events.ts))
- `internal/dispatch` — An event is being dispatched to listeners. ([`vendor/cordis/src/events.ts:342`](../../vendor/cordis/src/events.ts))
- `hmr/change` — A watched source file changed on disk. ([`vendor/hmr/src/index.ts:20`](../../vendor/hmr/src/index.ts))
- `hmr/reload` — Plugins are being reloaded after a change. ([`vendor/hmr/src/index.ts:21`](../../vendor/hmr/src/index.ts))
- `exit` — The process is exiting on a signal. ([`vendor/loader/src/index.ts:23`](../../vendor/loader/src/index.ts))
- `loader/config-update` — The loader config tree changed. ([`vendor/loader/src/index.ts:24`](../../vendor/loader/src/index.ts))
- `loader/entry-init` — A config entry is being initialized. ([`vendor/loader/src/index.ts:25`](../../vendor/loader/src/index.ts))
