feat(sdk,serve): DaemonTransport abstraction + ACP standard compliance (#5040)
* feat(sdk): DaemonTransport abstraction — pluggable transport for REST/ACP-HTTP/ACP-WS
- DaemonTransport interface with fetch + subscribeEvents
- RestSseTransport: extract current SSE logic from DaemonClient
- AcpWsTransport: WebSocket multiplexer + URL-to-JSON-RPC mapping
- AcpHttpTransport: POST /acp + session-scoped SSE
- AcpEventDenormalizer: JSON-RPC notification -> DaemonEvent
- AutoReconnectTransport: opt-in reconnect + fallback wrapper
- negotiateTransport(): auto-detect best transport via GET /capabilities
- Provider: DaemonWorkspaceProvider gains transport prop
- Server: GET /capabilities advertises supported transports
- Zero breaking changes: no transport = current REST behavior

* docs(design): include DaemonTransport design doc in implementation PR
* fix(sdk): address 6 verification findings — bundle size, WS hang, error types, ACP compat
- Remove ACP transport class re-exports from barrel (index.ts) to avoid
~19.7KB browser bundle bloat; keep type-only exports
- Fix WS dial hang: reject connect promise in onerror when not yet
connected (Node WebSocket may only fire error, not close)
- Fix parked generators: maintain _activeGenerators set, abort all on
WS close so generators throw DaemonTransportClosedError
- Forward abort signal through AcpHttpTransport.sendRequest to fetch
- Restore DaemonHttpError in RestSseTransport (was plain Error)
- ACP endpoint compat: extract connectionId from initialize, send
Acp-Connection-Id header, add _qwen/ prefix for vendor methods,
preserve real HTTP status in error mapping, fetch /capabilities
from REST endpoint for correct shape

* fix(sdk): address 16 review findings + CI bundle size
- CI: move negotiateTransport to separate file, extract DaemonHttpError
to break static import chain from barrel -> DaemonClient. Browser
bundle drops from 136KB to 115KB, under the 116KB budget.
- Route table: extract shared acpRouteTable.ts, used by both transports.
Unify method naming (remove _qwen/ prefix inconsistency).
- Token: move from URL query to Authorization header on WS upgrade
- Error type: DaemonHttpError extracted to DaemonHttpError.ts; import
in RestSseTransport no longer pulls in DaemonClient.
- Init retry: reset failed initPromise so next call retries
- Reconnect mutex: prevent concurrent reconnect storms
- Generator queue: cap at 256, drop-oldest
- WS init timeout: 30s default
- negotiate: clear timer on all paths, catch dispose rejection
- Headers: forward init.headers in ACP transports via mergeHeaders()
- Dead code: remove unused pendingRequests/sseAbort fields
- Provider: dispose client on unmount
- Helpers: extract matchRoute/synthesizeResponse/jsonRpcErrorToHttpStatus/
isRecord/composeAbortSignals to shared acpTransportUtils.ts
- Package exports: add deep import paths for ACP transports
- Tests: add AcpEventDenormalizer unit tests (17 cases)

* fix(sdk): fix 3 ACP wire bugs + bundle size + npm exports
Wire bugs (verified broken against real daemon):
1. AcpHttpTransport: read connectionId from response header + correct JSON path
2. AcpWsTransport: send token via Authorization header, not URL query
3. AcpEventDenormalizer: read params.update.sessionUpdate, not params.type
Bundle: remove negotiateTransport from barrel-reachable imports
Exports: add package.json deep import paths for ACP transports

* test(sdk): comprehensive ACP transport test suite (~175 tests)
- RestSseTransport: fetch delegation, SSE subscribe, auth, timeout, signal
- AcpWsTransport: route mapping, token auth, event filtering, queue cap
- AcpHttpTransport: connectionId extraction, header injection, init retry
- AutoReconnectTransport: reconnect mutex, fallback, delegation
- negotiateTransport: capability probing, timeout, fallback
- acpRouteTable: URL→method mapping, param extraction

* fix(sdk): route table coverage, browser WS auth, header forwarding, capabilities type
- Route table: add file/stat/list/glob/write/edit paths (all DaemonClient URLs)
- Route table: add session diagnostic routes (context, tasks, stats, rewind, language)
- Route table: add bulk sessions/delete
- WS auth: document browser limitation, Node uses headers, browser needs proxy
- Headers: forward X-Qwen-Client-Id via JSON-RPC _meta in WS transport
- DaemonCapabilities: add transports field to SDK type
- Package exports: remove unreachable deep exports, document monorepo usage
- Provider bypass: document limitation for glob/stat/list in workspace actions

* fix(serve,sdk): enforce ACP standard session/new — always isolated session
ACP standard mandates session/new MUST create a new isolated session.
Server-side (dispatch.ts):
- Force sessionScope='thread' on /acp session/new, ignoring client params
- REST POST /session retains 'single' default for backward compat
SDK-side (acpRouteTable.ts):
- Strip sessionScope from session/new params in ACP transports
- Document that ACP follows the standard (no extensions)

* fix(serve): ACP session/new returns standard models/modes fields
ACP standard NewSessionResponse includes optional `models` and `modes`
top-level fields alongside `configOptions`. Extract model/mode state
from configOptions and surface them as standard-shaped objects:
- models: { currentModelId, availableModels: [{id}] }
- modes: { currentModeId, availableModes: [{id}] }
Also update test to verify sessionScope is always forced to 'thread'
(ACP standard compliance — session/new always creates isolated session).

* feat(serve): add standard ACP methods session/set_mode, session/set_model, session/fork
Align /acp endpoint with ACP standard protocol:
- session/set_mode: dedicated method for mode changes (standard)
Maps to bridge.setSessionApprovalMode(). Params: {modeId, sessionId}
- session/set_model: dedicated method for model changes (unstable)
Maps to bridge.setSessionModel(). Params: {modelId, sessionId}
- session/fork: create a branched copy of an existing session
Maps to bridge.branchSession(). Response includes configOptions,
models, modes per ACP standard.
- session/load, session/resume: responses now include configOptions,
models, modes (per ACP LoadSessionResponse/ResumeSessionResponse)

proper {modelId, sessionId} matching SetSessionModelRequest

* fix(sdk,serve): align route table with dispatcher + AcpHttp SSE response correlation
Route table:
- Add _qwen/ prefix to all vendor session/workspace methods
- Split workspace catch-all into granular dispatcher methods
- Fix session/branch → session/fork, model → session/set_model
- Remove routes with no dispatcher handler
AcpHttpTransport:
- Implement conn-scoped SSE stream for response correlation
- POST returns 202 (ack), real response rides SSE stream
- Map<id, {resolve, reject}> for pending request correlation
dispatch.ts:
- Remove session/set_mode, session/set_model from CONN_ROUTED_METHODS

* fix(sdk): bump browser bundle budget 116KB→118KB for transport abstraction
Main uses 117,753 bytes (99.1% of 116KB budget). The transport
abstraction adds ~1.5KB (DaemonTransport interface + RestSseTransport
default constructor in DaemonClient). Bump to 118KB (120,832 bytes).
Also change RestSseTransport to type-only export from barrel (class
is constructed internally by DaemonClient, not needed as a value
export for consumers).

# DaemonTransport Abstraction Layer
|
||||
|
||||
> Target branch: `main`. Author: arnoo.gao. Date: 2026-06-12. Status: **Design v4 — review**.
|
||||
> Design-first per repo workflow: this doc lands before the implementation PR.
|
||||

|
||||
|
||||
## 0. TL;DR
|
||||
|
||||
`DaemonClient` hardcodes REST+SSE. Third-party integrations wanting ACP
|
||||
WebSocket must fork the provider stack (~8 files). This proposal adds a
|
||||
**`DaemonTransport` interface** with `fetch` + `subscribeEvents` methods,
|
||||
plus auto-detection and runtime fallback, enabling pluggable transports
|
||||
with **zero breaking changes**.
|
||||
|
||||
**Total change: ~1300 lines** in a single implementation PR. Existing
|
||||
consumers untouched — `new DaemonClient({ baseUrl, token })` = current behavior.
|
||||
|
||||
---
|
||||
|
||||
## 1. Background
|
||||
|
||||
### 1.1 Current architecture
|
||||
|
||||
```
|
||||
DaemonClient({ baseUrl, token })
|
||||
└─ this._fetch = globalThis.fetch ← hardcoded
|
||||
└─ subscribeEvents → GET /session/:id/events → parseSseStream → DaemonEvent
|
||||
```
|
||||
|
||||
67 public methods, each constructing REST URLs and branching on HTTP status
|
||||
codes. `fetch` is already injectable via `DaemonClientOptions.fetch`, but
|
||||
`subscribeEvents` has inline SSE-specific logic (content-type check, SSE parsing,
|
||||
connect-phase timeout) that cannot be swapped via fetch injection alone.
|
||||
|
||||
### 1.2 The problem for third parties
|
||||
|
||||
When a third party (e.g., `agent-web`) builds an `AcpSessionProvider` to use
|
||||
WebSocket instead of REST+SSE:
|
||||
|
||||
- **If they replace** `DaemonSessionProvider`: components that read
|
||||
`DaemonStoreContext` (e.g., TerminalView) lose their context → crash.
|
||||
- **If they keep both providers**: two event sources, two stores, desync.
|
||||
- **If they inject events** into the SDK store: `DaemonSessionProvider` also
|
||||
subscribes to SSE internally → duplicate events.
|
||||
|
||||
**Root cause**: changing the transport requires replacing the provider, because
|
||||
`DaemonClient`'s `subscribeEvents` is hardcoded to SSE.
|
||||
|
||||
### 1.3 Target
|
||||
|
||||
```
|
||||
DaemonClient({ transport: new AcpWsTransport(url, token) })
|
||||
└─ transport.fetch → maps URL+verb to JSON-RPC over WS
|
||||
└─ transport.subscribeEvents → demux WS notifications → DaemonEvent
|
||||
```
|
||||
|
||||
One provider, one store, transport is an internal detail. Third parties pass
|
||||
`transport` to `DaemonClient`; everything else works unchanged.
|
||||
|
||||
---
|
||||
|
||||
## 2. Design
|
||||
|
||||
### 2.1 Interface
|
||||
|
||||
```typescript
|
||||
interface DaemonTransportFetchOptions {
|
||||
timeout?: number; // 0 = no timeout. undefined = transport default.
|
||||
}
|
||||
|
||||
interface DaemonTransportSubscribeOptions {
|
||||
lastEventId?: number;
|
||||
maxQueued?: number;
|
||||
signal?: AbortSignal;
|
||||
connectTimeoutMs?: number;
|
||||
}
|
||||
|
||||
interface DaemonTransport {
|
||||
/**
|
||||
* Send a request and return a Response.
|
||||
*
|
||||
* Contract:
|
||||
* - Response MUST support .json(), .text(), .ok, .status,
|
||||
* .headers.get(), .body?.cancel()
|
||||
* - .status MUST be an accurate HTTP status code
|
||||
* (200, 201, 202, 204, 404, etc.)
|
||||
* - Error bodies MUST preserve the daemon's structured shape
|
||||
* - Callable without prior setup; transport handles init internally
|
||||
* (lazy-init / init-once deferred pattern)
|
||||
* - Throws DaemonTransportClosedError when connection is dead
|
||||
* - When init.signal aborts: for prompt requests, transport MUST
|
||||
* cancel the in-flight prompt on the wire (WS: send session/cancel
|
||||
* RPC; HTTP: abort fetch). For ordinary requests, abort only
|
||||
* rejects/cancels the pending request without side effects.
|
||||
* Pending response rejects with AbortError.
|
||||
*/
|
||||
fetch(
|
||||
url: string,
|
||||
init: RequestInit,
|
||||
opts?: DaemonTransportFetchOptions,
|
||||
): Promise<Response>;
|
||||
|
||||
/**
|
||||
* Subscribe to session events.
|
||||
*
|
||||
* Contract:
|
||||
* - Events with id MUST have monotonic integer ids; synthetic/terminal
|
||||
* frames (e.g., stream_error) MAY omit id (DaemonEvent.id is optional)
|
||||
* - MUST deliver ALL event types (session + workspace) in one stream
|
||||
* - Aborting signal MUST stop only this generator, NOT the connection
|
||||
* - When the connection dies, all pending generators MUST throw
|
||||
* DaemonTransportClosedError (transport maintains generator refs)
|
||||
* - MUST apply connectTimeoutMs to connect phase only
|
||||
* - Transport MUST declare whether lastEventId replay is supported;
|
||||
* if not, consumer MUST use session/load for full resync on reconnect
|
||||
*/
|
||||
subscribeEvents(
|
||||
sessionId: string,
|
||||
opts: DaemonTransportSubscribeOptions,
|
||||
): AsyncGenerator<DaemonEvent>;
|
||||
|
||||
/** Transport identity for exhaustive switching. */
|
||||
readonly type: 'rest' | 'acp-http' | 'acp-ws';
|
||||
|
||||
/** Whether this transport supports Last-Event-ID based replay on reconnect.
|
||||
* When false, consumer MUST use session/load for full resync. */
|
||||
readonly supportsReplay: boolean;
|
||||
|
||||
/** False after connection drop or dispose(). */
|
||||
readonly connected: boolean;
|
||||
|
||||
/** Idempotent teardown. */
|
||||
dispose(): void;
|
||||
}
|
||||
|
||||
class DaemonTransportClosedError extends Error {}
|
||||
```
|
||||
|
||||
### 2.2 Why two methods (fetch + subscribeEvents), not just fetch
|
||||
|
||||
`subscribeEvents` has fundamentally different wire semantics per transport:
|
||||
|
||||
| Transport | Wire mechanism |
|
||||
|-----------|---------------|
|
||||
| REST | `GET /session/:id/events` → SSE → `parseSseStream` → `DaemonEvent` |
|
||||
| ACP HTTP | `GET /acp` (session-scoped SSE) → JSON-RPC notification unwrap |
|
||||
| ACP WS | Demux notifications from shared socket by sessionId |
|
||||
|
||||
Forcing these through a fetch-shaped hole requires SSE re-encoding/decoding
|
||||
(WS → fake SSE text → `parseSseStream` → DaemonEvent) — wasteful and fragile.
|
||||
|
||||
All other 66 methods work through `fetch` because they follow request→response
|
||||
semantics regardless of transport.
|
||||
|
||||
### 2.3 Why fetch-level, not method-dispatch
|
||||
|
||||
DaemonClient's 67 methods contain per-method HTTP branching:
|
||||
- `prompt()`: 202 vs 200 status check
|
||||
- `deleteWorkspaceAgent()`: 204 vs 404 with body inspection
|
||||
- `respondToPermission()`: 200 vs 404 for race detection
|
||||
- 6 methods bypass `fetchWithTimeout` by calling `_fetch` directly
|
||||
|
||||
A method-dispatch interface (`request<T>(method, params)`) forces duplicating
|
||||
all this logic in every transport. Fetch-level keeps DaemonClient unchanged.
|
||||
|
||||
### 2.4 DaemonClient changes (~40 lines)
|
||||
|
||||
```typescript
|
||||
export interface DaemonClientOptions {
|
||||
baseUrl: string;
|
||||
token?: string;
|
||||
fetch?: typeof globalThis.fetch; // Kept
|
||||
fetchTimeoutMs?: number; // Kept
|
||||
transport?: DaemonTransport; // NEW — optional override
|
||||
}
|
||||
```
|
||||
|
||||
Internal changes:
|
||||
- Constructor: `this.transport = opts.transport ?? new RestSseTransport(...)`
|
||||
- `fetchWithTimeout`: delegate to `this.transport.fetch(url, init, { timeout })`
|
||||
- 6 direct `this._fetch` sites (prompt, promptNonBlocking, recapSession,
|
||||
btwSession, shellCommand, subscribeEvents): replace with
|
||||
`this.transport.fetch(url, init, { timeout: 0 })`
|
||||
- `subscribeEvents`: exhaustive switch on `this.transport.type`:
|
||||
- `'rest'`: delegate to `this.transport.subscribeEvents(sessionId, opts)`
|
||||
- default: same delegation (each transport handles its own wire format)
|
||||
- Remove `private _fetch` field (replaced by transport)
|
||||
|
||||
### 2.5 Provider injection point
|
||||
|
||||
`DaemonWorkspaceProvider` and `DaemonSessionProvider` both construct
|
||||
`DaemonClient` internally. To let third parties inject a transport without
|
||||
bypassing the provider:
|
||||
|
||||
```typescript
|
||||
// DaemonWorkspaceProvider — add optional transport prop
|
||||
interface DaemonWorkspaceProviderProps {
|
||||
baseUrl: string;
|
||||
token?: string;
|
||||
transport?: DaemonTransport; // NEW — forwarded to DaemonClient
|
||||
// ...existing props
|
||||
}
|
||||
|
||||
// DaemonSessionProvider — inherit from workspace context
|
||||
// No transport prop needed; reads from workspace context
|
||||
```
|
||||
|
||||
When `transport` is provided, the provider passes it to `DaemonClient`:
|
||||
```typescript
|
||||
new DaemonClient({ baseUrl, token, transport: props.transport })
|
||||
```
|
||||
|
||||
When omitted: current behavior (REST+SSE). ~5 lines of provider change.
|
||||
|
||||
### 2.5 RestSseTransport (~80 lines)
|
||||
|
||||
Wraps `globalThis.fetch` + extracts current SSE logic from
|
||||
`DaemonClient.subscribeEvents`:
|
||||
|
||||
```typescript
|
||||
class RestSseTransport implements DaemonTransport {
|
||||
readonly type = 'rest' as const;
|
||||
readonly supportsReplay = true; // SSE supports Last-Event-ID
|
||||
readonly connected = true; // REST is stateless
|
||||
|
||||
constructor(
|
||||
private readonly baseUrl: string,
|
||||
private readonly token: string | undefined,
|
||||
private readonly _fetch: typeof globalThis.fetch,
|
||||
) {}
|
||||
|
||||
fetch(url, init, opts?) { return this._fetch(url, init); }
|
||||
|
||||
async *subscribeEvents(sessionId, opts) {
|
||||
// Current DaemonClient.subscribeEvents logic moved here:
|
||||
// - build URL from this.baseUrl + sessionId
|
||||
// - set Authorization header from this.token
|
||||
// - connect-phase timeout from opts.connectTimeoutMs
|
||||
// - fetch → validate content-type → parseSseStream → yield
|
||||
}
|
||||
|
||||
dispose() {} // no-op
|
||||
}
|
||||
```
|
||||
|
||||
### 2.6 ACP transport internals
|
||||
|
||||
**AcpWsTransport** (~400-600 lines):
|
||||
- Lazy-init: first `fetch` call opens WS + sends `initialize`
|
||||
- URL→JSON-RPC mapping table: `/session/:id/prompt` → `{method: "session/prompt", params: {sessionId: id, ...body}}`
|
||||
- Request multiplexer: `Map<id, {resolve, reject}>` for pending requests
|
||||
- `subscribeEvents`: filter shared notification stream by sessionId
|
||||
- `connected`: tracks WS readyState
|
||||
- `supportsReplay`: false (WS has no Last-Event-ID; consumer must `session/load`)
|
||||
- Synthesizes `Response` objects with correct `.status`/`.json()`/`.text()`
|
||||
|
||||
**AcpHttpTransport** (~800-1000 lines):
|
||||
- Lazy-init: first `fetch` call sends `POST /acp {initialize}`
|
||||
- Manages conn-scoped + session-scoped SSE streams internally
|
||||
- Same URL→JSON-RPC mapping + request correlation
|
||||
- `supportsReplay`: true (session SSE supports Last-Event-ID)
|
||||
|
||||
### 2.7 Transport auto-detection
|
||||
|
||||
Server advertises supported transports in `GET /capabilities`:
|
||||
|
||||
```json
|
||||
{
|
||||
"transports": ["rest+sse", "acp-http+sse", "acp-ws"],
|
||||
...existing capabilities fields...
|
||||
}
|
||||
```
|
||||
|
||||
SDK provides a one-shot static factory:
|
||||
|
||||
```typescript
|
||||
// Probe once before React render, never switches mid-session
|
||||
const transport = await DaemonTransport.negotiate(baseUrl, token);
|
||||
// Returns best available: acp-ws > acp-http > rest (fallback)
|
||||
```
|
||||
|
||||
Implementation:
|
||||
1. `GET /capabilities` → read `transports` array
|
||||
2. If `acp-ws` in list → try WS upgrade; on success return `AcpWsTransport`
|
||||
3. If WS fails or not in list → try `acp-http`; on success return `AcpHttpTransport`
|
||||
4. Fallback → `RestSseTransport`
|
||||
|
||||
No existing API affected: `GET /capabilities` adds a new field (additive),
|
||||
existing consumers ignore unknown fields.
|
||||
|
||||
### 2.8 Runtime fallback (WS → REST on disconnect)
|
||||
|
||||
When a non-REST transport disconnects mid-session:
|
||||
|
||||
```
|
||||
AcpWsTransport (connected=true)
|
||||
│
|
||||
├── WS drops (network, server restart, idle timeout)
|
||||
│
|
||||
├── connected = false
|
||||
├── All pending fetch() calls → reject with DaemonTransportClosedError
|
||||
├── All subscribeEvents generators → throw DaemonTransportClosedError
|
||||
│
|
||||
└── Consumer (Provider / third party) detects disconnect:
|
||||
1. Create new RestSseTransport (guaranteed to work if daemon is up)
|
||||
2. Create new DaemonClient({ transport: newTransport })
|
||||
3. For each active session: session/load to re-attach
|
||||
4. Resume event subscription
|
||||
```
|
||||
|
||||
**Key constraint**: runtime fallback is **consumer-driven, not transport-internal**.
|
||||
The transport does not silently switch protocols — it fails loudly
|
||||
(`DaemonTransportClosedError`) and the consumer decides whether to rebuild.
|
||||
|
||||
Rationale:
|
||||
- WS teardown destroys all owned sessions server-side (`registry.delete` →
|
||||
`conn.destroy`). A silent switch would hide this data loss.
|
||||
- `session/load` re-attaches to the existing bridge session (transcripts
|
||||
preserved), but the prompt in flight is aborted. The consumer must handle
|
||||
this explicitly (retry or surface to user).
|
||||
- No `Last-Event-ID` resume across transports yet (Phase 4). Events between
|
||||
disconnect and reconnect may be lost. The consumer should request a full
|
||||
state resync via `session/load` (which replays history).
|
||||
|
||||
**AutoReconnectTransport** (~150 lines, optional wrapper):
|
||||
|
||||
```typescript
|
||||
class AutoReconnectTransport implements DaemonTransport {
|
||||
constructor(
|
||||
private baseUrl: string,
|
||||
private token: string,
|
||||
private preferred: 'acp-ws' | 'acp-http' | 'rest',
|
||||
) {}
|
||||
|
||||
// On DaemonTransportClosedError from inner transport:
|
||||
// 1. Try to re-create preferred transport
|
||||
// 2. If preferred fails, fallback to REST
|
||||
// 3. Re-initialize connection
|
||||
// Caller still needs to session/load — this wrapper only
|
||||
// handles transport-level reconnect, not session-level.
|
||||
}
|
||||
```
|
||||
|
||||
This wrapper is opt-in. Existing consumers who don't want auto-reconnect
|
||||
simply catch `DaemonTransportClosedError` and handle it themselves.
|
||||
|
||||
**Impact on existing functionality**: zero. All auto-detection and fallback
|
||||
code is additive and opt-in. `new DaemonClient({ baseUrl, token })` without
|
||||
`transport` = current REST behavior, no auto-detection, no fallback logic.
|
||||
|
||||

|
||||
|
||||
## 3. Breaking change audit
|
||||
|
||||
### Verdict: zero breaking changes
|
||||
|
||||
| Public API | Change | Breaking? |
|
||||
|-----------|--------|:---------:|
|
||||
| `new DaemonClient({ baseUrl, token })` | No change | ❌ |
|
||||
| `DaemonClientOptions.*` | All kept, `transport` added | ❌ |
|
||||
| `DaemonHttpError` | Unchanged | ❌ |
|
||||
| `DaemonSessionClient` | Zero changes (delegates to DaemonClient) | ❌ |
|
||||
| All type exports (100+) | Unchanged | ❌ |
|
||||
|
||||
### Per-consumer impact
|
||||
|
||||
| Consumer | Impact |
|
||||
|----------|--------|
|
||||
| webui (25 files) | Zero code changes |
|
||||
| web-shell (4 files) | Zero code changes |
|
||||
| vscode-ide-companion (1 file) | Zero code changes |
|
||||
| Third-party | Zero for REST; pass `transport` for ACP |
|
||||
|
||||
---
|
||||
|
||||
## 4. Design decisions
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| `subscribeEvents` on transport, not just `fetch` | SSE re-encoding through fetch is wasteful and fragile |
|
||||
| `connected: boolean` on transport | Provider reconnect loop needs to distinguish "transport dead" from "transient 500" |
|
||||
| Lazy-init (not explicit `connect()`) | Keeps DaemonClient construction synchronous; default `new RestSseTransport()` needs no init |
|
||||
| Auto-detection is one-shot, not mid-session | `negotiate()` probes once at startup; runtime fallback is consumer-driven via `DaemonTransportClosedError`, not silent internal switch |
|
||||
| No error taxonomy prerequisite | ACP transports map errors to HTTP-equivalent status codes internally; `DaemonHttpError` works as-is |
|
||||
| Provider gets `transport` prop | `DaemonWorkspaceProvider` gains optional `transport` prop (~5 lines), forwarded to `DaemonClient` constructor. Third parties set this prop; omitting it = current REST behavior |
|
||||
|
||||
---
|
||||
|
||||
## 5. Alternatives considered
|
||||
|
||||
### 5.1 Custom fetch injection (no new interface)
|
||||
|
||||
Pass a WS-based `fetch` via existing `DaemonClientOptions.fetch`.
|
||||
|
||||
**Rejected**: `subscribeEvents` validates `content-type: text/event-stream` and
|
||||
uses `parseSseStream`. A custom fetch must re-encode WS frames as SSE text, then
|
||||
the SDK decodes them back — wasteful encode-decode roundtrip. Also,
|
||||
`capabilities()` and `initialize` have different response shapes requiring a
|
||||
format mapping layer.
|
||||
|
||||
### 5.2 Full formal interface (4 PRs, ~2750 lines)
|
||||
|
||||
Error taxonomy → Interface → AcpHttp → AcpWs as separate PRs.
|
||||
|
||||
**Rejected**: over-engineered. Error taxonomy is unnecessary (ACP transports can
|
||||
map to HTTP-equivalent status codes). Separate PRs increase review context-switch
|
||||
cost for a single cohesive abstraction.
|
||||
|
||||
### 5.3 Dual provider with BridgeContext
|
||||
|
||||
Parallel `AcpSessionProvider` + `ChatBridgeContext` + `SessionBridgeContext`.
|
||||
|
||||
**Rejected**: causes store desync, requires ~8 files, cannot work without SDK changes.
|
||||
|
||||
---
|
||||
|
||||
## 6. Implementation plan (single PR)
|
||||
|
||||
All changes land in one PR. Estimated ~1300 lines total.
|
||||
|
||||
| File | Change | Lines |
|
||||
|------|--------|-------|
|
||||
| `packages/sdk-typescript/src/daemon/DaemonTransport.ts` | Interface + types + `DaemonTransportClosedError` + `negotiate()` factory | ~110 |
|
||||
| `packages/sdk-typescript/src/daemon/RestSseTransport.ts` | Wraps `globalThis.fetch` + SSE logic extracted from DaemonClient | ~80 |
|
||||
| `packages/sdk-typescript/src/daemon/AcpWsTransport.ts` | WS multiplexer + URL→JSON-RPC mapping + request correlation | ~400 |
|
||||
| `packages/sdk-typescript/src/daemon/AcpHttpTransport.ts` | POST /acp + conn/session SSE management | ~300 |
|
||||
| `packages/sdk-typescript/src/daemon/AcpEventDenormalizer.ts` | JSON-RPC notification → DaemonEvent mapping | ~150 |
|
||||
| `packages/sdk-typescript/src/daemon/AutoReconnectTransport.ts` | Opt-in wrapper: reconnect + fallback | ~150 |
|
||||
| `packages/sdk-typescript/src/daemon/DaemonClient.ts` | Constructor + 6 `_fetch` sites + subscribeEvents rewrite | ~40 net |
|
||||
| `packages/sdk-typescript/src/daemon/index.ts` | Export new types | ~10 |
|
||||
| `packages/cli/src/serve/server.ts` | Add `transports` field to `GET /capabilities` | ~5 |
|
||||
| `packages/sdk-typescript/src/daemon/types.ts` | Add `transports` to `DaemonCapabilities` type | ~3 |
|
||||
| `packages/webui/src/daemon/workspace/DaemonWorkspaceProvider.tsx` | Add optional `transport` prop, forward to `DaemonClient` | ~5 |
|
||||
| Tests | Transport unit + integration tests | ~200 |
|
||||
|
||||
**Backward compatibility**: `new DaemonClient({ baseUrl, token })` without
|
||||
`transport` = identical REST+SSE behavior. All existing tests pass unchanged.
|
||||
|
||||
---
|
||||
|
||||
## 7. Verification
|
||||
|
||||
1. **Backward compat**: `npm run test` across sdk-typescript and webui — zero
|
||||
test changes needed. `new DaemonClient({ baseUrl, token })` = identical behavior.
|
||||
2. **RestSseTransport extraction**: bit-for-bit equivalent SSE behavior confirmed
|
||||
by existing test suite.
|
||||
3. **AcpWsTransport**: integration test connecting to real daemon via WS. Verify:
|
||||
- `subscribeEvents` yields same `DaemonEvent` shapes as REST SSE
|
||||
- prompt 202/200 branching works with synthesized Response
|
||||
- permission vote round-trips correctly
|
||||
- `connected` transitions to `false` on WS drop
|
||||
- abort signal on prompt → WS sends session/cancel RPC
|
||||
4. **AcpHttpTransport**: same verification as WS but over HTTP+SSE.
|
||||
5. **Auto-detect**: `negotiate()` returns best transport; fallback to REST on WS failure.
|
||||
6. **Runtime fallback**: `AutoReconnectTransport` catches `DaemonTransportClosedError`,
|
||||
rebuilds transport, consumer calls `session/load` for resync.
|
||||
7. **Provider**: `DaemonWorkspaceProvider` with `transport` prop — ChatView +
|
||||
TerminalView both read from single store.
|
||||
8. **End-to-end**: Third-party passes `transport={new AcpWsTransport(url, token)}`
|
||||
to `DaemonWorkspaceProvider`. All SDK hooks and transcript store work unchanged.

## 8. Risks
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|-----------|
|
||||
| URL→JSON-RPC mapping table maintenance | Table co-located with transport; daemon route changes require transport update |
|
||||
| ACP WS synthesized Response fidelity | Provide `syntheticResponse(status, json)` helper; document contract (`.json()`, `.text()`, `.status`, `.body?.cancel()`) |
|
||||
| `DaemonEvent.id` monotonicity for WS | ACP server's JSON-RPC notifications carry event id; transport surfaces it directly |
|
||||
| Prompt 202 vs 200 for WS | Transport maps JSON-RPC response → 200 with result body (blocking path); events still flow via `subscribeEvents` |
|
||||
| WS connection drop detection | `connected: boolean` + `DaemonTransportClosedError` thrown from `fetch` |
