Conflict resolution notes: - package.json/run-gates: both sides' new doc-sync gates kept (master's scoped-events/readme gates + this branch's website-api/website-yaml); js-yaml devDeps deduped (master added them independently). - pnpm-workspace/knip: website AND python/sdk-runtime entries kept. - doc-typecheck/verify-type-equiv: master's condensed headers kept, website glob retained in both scan scopes. - vendor/cordis/src/fiber.ts: master's lifecycle-hardening code taken; this branch's richer FiberState JSDoc reapplied on top. vendor/README.md logs both local modifications (hardening = 6, JSDoc enrichment = 7). - pnpm-lock: regenerated from master's side (pnpm install). Post-merge sync the gates forced (the system working as designed): - verify-website-yaml caught 4 stale plugin names from master's package reorg (dsh-stdio-agent -> dsh-stdio-demo, dsh-acp-agent -> dsh-acp-demo); 8 references fixed across guide/ and develop/. - gen-website-api picked up master's 6 new services automatically (ctx.approval/permission/sandbox/sessionQuery/skills/tasks -> 6 new pages + sidebar); api/index.md hub updated to list them. - AGENTS.md budget ceiling 1370 -> 1400: the website rows (layout line + two command lines) and master's own growth collided with the old ceiling; all three website rows are load-bearing (new top-level dir, new CI command).

# ctx.sessions
|
|
|
|
`SessionStore` — provided by `@deepseek-ai/dsh-session`.
|
|
|
|
In-memory session store (`ctx.sessions`).
|
|
Persistence is intentionally not implemented here — persistence plugins subscribe to `session/event` and flush on `session/flush` / dispose.
|
|

### ctx.sessions.create(id?, options?)
|
|
|
|
```ts website-api
|
|
create(id?: SessionId, options?: CreateSessionOptions): Session
|
|
```
|
|
|
|
Create a session owned by the calling fiber: disposing that fiber stops event notification and removes the session from the store. `options.seed` populates the session with a copy of those events (replay/fork); `options.meta` attaches creation metadata (validated absolute `cwd`, `parentSession` lineage) as the immutable SessionHeader (the store fills `version`/`id`/`createdAt`).
|
|
For an agent whose session must be torn down IN ORDER with its loop (so the loop's final flush is captured before the store attachment ends), do NOT use this — fold the session lifecycle into the agent's own effect via prepare + enter + announce (see `dsh-agent-loop`'s creation transaction).
|
|
|
|
- `id` — the session id; omitted, the store mints `session-<n>`.
|
|
- `options` — seed events and/or creation metadata for the header.
|
|
|
|
**Returns** the live session, already entered and announced.

### ctx.sessions.prepare(id?, options?)
|
|
|
|
```ts website-api
|
|
prepare(id?: SessionId, options?: CreateSessionOptions): Session
|
|
```
|
|
|
|
Build a session WITHOUT entering it into the store — validate the id/cwd and construct the Session (with its immutable SessionHeader). Pairs with enter + announce: a caller that owns a composite `ctx.effect` (the agent factory) folds the session lifecycle into that ONE effect so a fiber unload tears the session + agent down as a single ORDERED chain rather than as racing sibling effects — which would remove the publication hooks before the loop's closing `session/flush`, dropping the closing events.
|
|
|
|
- `id` — the session id; omitted, the store mints `session-<n>`.
|
|
- `options` — seed events and/or creation metadata for the header.
|
|
|
|
**Returns** the constructed session, NOT yet in the store.
|

### ctx.sessions.enter(session)
|
|
|
|
```ts website-api
|
|
enter(session: Session): () => void
|
|
```
|
|
|
|
Enter a prepared session into the store: install the module-private append publication hooks and add it to the store. Returns the DETACH disposer (hooks + store removal). Does NOT emit `session/created` — the caller yields this disposer inside its effect and THEN calls announce, so a throwing `session/created` listener rolls the attach back instead of leaking it.
|
|
Re-checks the id for a duplicate: `prepare` and `enter` are public cross-package primitives and a caller may interleave arbitrary work (or another create) between them, so a stale prepared session must NOT overwrite a live store entry of the same id — its detach disposer would later delete the REAL session. The create convenience and the agent factory call the two back-to-back so they never trip this, but the public seam cannot assume that.
|
|
|
|
- `session` — a `prepare`d session not yet in the store.
|
|
|
|
**Returns** the detach disposer (publication hooks + store removal). When called from a synchronous `session/created` listener, removal and disposal wait until that creation dispatch unwinds.
|
|
|

### ctx.sessions.announce(session)
|
|
|
|
```ts website-api
|
|
announce(session: Session): void
|
|
```
|
|
|
|
Emit `session/created` exactly once for an entered session (with the carrier enter captured). Separate from enter so the caller can yield the detach disposer first (rollback safety — see enter).
|
|
|
|
- `session` — the entered session to announce to listeners.
|
|
|
|

|

|
|
### ctx.sessions.flush(session)
|
|
|
|
```ts website-api
|
|
async flush(session: Session): Promise<void>
|
|
```
|
|
|
|
Dispatch the awaited `session/flush` durability checkpoint for `session`, with the carrier captured at enter. THE flush entry point: the store owns the carrier, so callers (the loop's turn-end checkpoint, idle injection, teardown drains) must come through here rather than dispatch a raw `ctx.parallel('session/flush', …)` — one owner, one spelling, and the scoped-dispatch invariant can pin it.
|
|
|
|
- `session` — the session whose buffered events must reach durable storage.
|
|
|
|
**Returns** resolves when every flush listener has settled; after all settle, rejects with the first registered listener failure if any listener failed.

### ctx.sessions.get(id)
|
|
|
|
```ts website-api
|
|
get(id: SessionId): Session | undefined
|
|
```
|
|
|
|
Look up a live session.
|
|
|
|
- `id` — the session id to look up.
|
|
|
|
**Returns** the session, or undefined when no live session has that id.
|

|
### ctx.sessions.list()
|
|
|
|
```ts website-api
|
|
list(): Session[]
|
|
```
|
|
|
|
All live sessions, in creation order.
|
|
|
|
**Returns** a fresh array; mutating it does not affect the store.
|

### ctx.sessions.fork(source, boundary?, childSessionId?)
|
|
|
|
```ts website-api
|
|
fork(source: SessionForkSource, boundary?: number, childSessionId?: SessionId): Session
|
|
```
|
|
|
|
Create a live child session from a turn-enclosed prefix of a live source. `boundary` is an inclusive source event seq; omitted means the source's current last event. A non-empty selected slice must end at `turn/end`.
|
|
|
|
- `source` — Live source session object or id.
|
|
- `boundary` — Inclusive source event seq to fork through; omitted means the source's current last event, and omitted on an empty source forks an empty child.
|
|
- `childSessionId` — Optional child session id; omitted delegates to `SessionStore`'s id policy.
|
|
|
|
**Returns** The created live child session.
