将全部 7 个 Source Provider 的配置、密钥、应用验证和远端资源状态交由 Connector 管理。Open Flow 保存不透明引用与公开视图,负责消费者绑定、发布、checkpoint、事件去重及 Run 准入。

Poll 保持原有业务契约:10 个 Poll 的 definitionVersion 仍为 2,输出 events[],每个非空去重结果页进入一个批量 Run。新建与已有 Flow 使用相同语义。已撤回单事件执行、v3 定义、兼容快照及 Trigger refresh 升级路径,不新增模式开关;无需修改下游数组映射或增加 Run 数量。

  • Source 操作支持未完成请求恢复、共享应用回调路由、资源清理及断开连接后的删除;按团队过滤列表,保留取消语义。
  • 使用 Connector callback 元数据,支持创建期间握手。
  • 新增迁移 54、共享协议及纵向验证脚本、架构和发布基线文档。
  • poll-batch CLI/MCP Lab 验证公共创建、读取、局部更新,以及同一 Run 中的多消息数组消费。

验证:

  • 根目录 bun run check 通过。
  • Open Flow 产品包:237 个文件、2,951 个测试通过。
  • Server:95 个文件、1,202 个测试通过。新增回归确认待执行容量仅为 1 时,三条去重事件仍完整进入同一个 Run,重复读取不新增 Run。
  • 实际 npm tarball、浏览器运行时及 CLI 消费端验证通过。
  • poll-batch CLI 和 MCP Lab 均通过,每次 Run 消费完整的两消息数组。
  • Connector 共享行为、36 个 catalog 和 Open Flow 纵向链路验证通过;10 个 Poll 快照与改造前完全一致。

Summary by CodeRabbit

  • New Features
    • Event sources now support connector-managed creation, updates, verification, delivery, and deletion. Interrupted operations can recover when processing resumes.
    • Gmail Poll runs can deliver a batch of unique events together.
  • Bug Fixes
    • Source changes and deletions are checked against active consumers and subscriptions, helping prevent unsafe changes.
    • Callback requests forward configured provider headers and query parameters. Busy sources can be retried during delivery.
  • Documentation
    • Added guidance on Poll batch behavior and connector operations.
  • Migration
    • Database upgrades stop when legacy event sources are present; resolve them before upgrading.

Walkthrough

The Server now uses Connector source references for Source lifecycle operations, callback routing, delivery, and resource changes. It persists Connector references and pending-operation state, and migration 54 rejects databases that contain legacy Sources. Connector requests support Source ingress and status-aware errors. The changes also add a Poll batch lab scenario and validation coverage. Poll remains on its existing batch contract.

Priority: Normal

Merge Risk: Minimal · up to 86aa7

The Poll capacity concern does not block merging: an overloaded Poll releases its claim and retries, while the updated Lab checks its effective configuration.

Pre-merge checks: Passed 4
Check name Status Explanation
Title check Passed The title uses the required format type(scope): subject, is in English, and accurately describes the connector-owned source changes.
Description check Passed The description directly explains the connector-owned Source architecture, Poll compatibility, migrations, tests, and deployment constraints covered by the changeset.
Linked Issues check Passed Check skipped because no linked issues were found for this pull request.

Inline comments:
Review comments at @apps/server/node/runtime/listener-runtime.ts:
- Around line 537-538: Update the capacity check in the Effect.gen flow to
return the PermanentPollError through the Effect failure channel using
Effect.fail instead of throwing it, so the existing Effect.catch path can handle
the failure.

Review comments at @packages/open-flow/src/control/common/authoringSchema.ts:
- Line 286: Update the Poll delivery guidance in the authoring schema string to
distinguish definition versions: version 3 emits one event per Run using
`event`, while version 2 retains the `events` array in batch Runs. Keep the
surrounding guidance unchanged.

Review comments at
@packages/open-flow/src/trigger/providers/fieldDescriptions.ts:
- Line 10: Update the shared pageSize description in fieldDescriptions.ts to
describe only the maximum number of changes read per page; remove the claim that
each event starts a separate Run.

# Fallback

Fallback operators recover from typed failures. Defects and interruptions remain unchanged.

## catch

`Effect.catch` receives the error and returns a fallback Effect. If the source succeeds, the fallback is not evaluated.

Example (Recovering with Another Effect)
    
    `
    
    1
    
    import { Effect } from &quot;effect&quot;
    
    2
    
    
    
    
    3
    
    const primary = Effect.fail(&quot;primary unavailable&quot;)
    
    4
    
    
    
    
    5
    
    const program = primary.pipe(
    
    6
    
      Effect.catch((error) =&gt; Effect.succeed(`fallback: ${error}`)),
    
    7
    
    )
    
    8
    
    
    
    
    9
    
    Effect.runSync(program) // =&gt; &quot;fallback: primary unavailable&quot;
    
    `

Use `Effect.catchTag`, `Effect.catchIf`, or `Effect.catchFilter` when only part of the error channel should trigger the fallback.

## orElseSucceed

`Effect.orElseSucceed` replaces any typed failure with a lazily evaluated success value and removes the typed error channel.

Example (Providing a Default Value)

### Patch Changes

  * #7483 `b945ded` Thanks @tim-smart! - Align runtime type IDs with their module paths. Effect markers now omit legacy grouping prefixes and the `unstable` path segment, while OpenTelemetry spans use the `OtelTracer` module path. Custom implementations that copy these marker strings must adopt the corrected IDs.

  * #7643 `9956f0e` Thanks @tim-smart! - Reduce memory usage in Effect primitives and fibers.

Breaking: context-derived `Fiber` fields now live under `fiber.cache`. ## 4.0.0-rc.112

<excerpt>citeturn1search5 [wordlim: 200] Crawled: 4 days ago; Generated JSON Schema now says `&quot;additionalProperties&quot;: true`  | JSON Schema generation is open by default.  | `{ onExcessProperty: &quot;error&quot; }`; refresh snapshots. ... Code from elsewhere fails with &quot;Cannot find module&quot; or missing exports  | It was written for Effect 3 or imports a path that is not part of Effect 4. ... Calling a function that returns an Effect, placing an Effect inside `Effect.sync`, or constructing one inside an unreturned callback does not execute it. ... Defects come from `Effect.die(value)`, from `Effect.orDie`, from a rejection inside `Effect.promise`, and from any `throw` the runtime catches outside a `try` constructor — inside `Effect.sync`, an `Effect.map` callback, or the body of `Effect.gen`. ...     declare const runBandImportPlugin: Effect.Effect&lt;string, &quot;BandFileMissing&quot;&gt; ... Effect.logError(&quot;band import plugin crashed&quot;, { message: defect.message }).pipe( ...           : Effect.die(defect) // not ours: do not swallow an unknown bug

The fragment keeps the adapter short to show the channels. A production adapter also declares and forwards the `signal` that `Effect.tryPromise` offers — `try: (signal) =&gt; fetch(url, { signal })` — because without the parameter no `AbortController` is created and an interrupted fiber leaves the request running (Cancellable adapters).

Defects come from `Effect.die(value)`, from `Effect.orDie`, from a rejection inside `Effect.promise`, and from any `throw` the runtime catches outside a `try` constructor — inside `Effect.sync`, an `Effect.map` callback, or the body of `Effect.gen`. When a boundary promotes a typed failure deliberately, `Effect.mapError` it into a descriptive `Error` first so the defect is diagnosable.

Use `Effect.exit` when success/failure should become data and `Effect.catchCause` when cleanup, reporting, or a true boundary must examine the complete cause. Do not catch every Cause and pretend interruption or defects are ordinary domain failures; doing so can prevent shutdown and hide bugs.

# Effect Library Development Patterns

## NEVER: try-catch in Effect.gen

REASON: Effect generators handle errors through the Effect type system, not JavaScript exceptions.
    
    // ❌ WRONG - This will cause runtime errors
    Effect.gen(function*() {
      try {
        const result = yield* someEffect
        return result
      } catch (error) {
        // This will never be reached and breaks Effect semantics
        console.error(error)
      }
    })
    
    // ✅ CORRECT - Use Effect&#39;s built-in error handling
    Effect.gen(function*() {
      const result = yield* Effect.result(someEffect)
      if (result._tag === &quot;Failure&quot;) {
        // Handle error case properly
        console.error(&quot;Effect failed:&quot;, result.cause)
        return yield* Effect.fail(&quot;Handled error&quot;)
      }
      return result.value
    })

## return yield* Pattern for Errors

CRITICAL: Always use `return yield*` when yielding terminal effects.
    
    // ✅ CORRECT - Makes termination explicit
    Effect.gen(function*() {
      if (invalidCondition) {
        return yield* Effect.fail(&quot;Validation failed&quot;)
      }
    
      if (shouldInterrupt) {
        return yield* Effect.interrupt
      }
    
      // Continue with normal flow
      const result = yield* someOtherEffect
      return result
    })
    
    // ❌ WRONG - Missing return keyword leads to unreachable code
    Effect.gen(function*() {
      if (invalidCondition) {
        yield* Effect.fail(&quot;Validation failed&quot;) // Missing return!
        // Unreachable code after error!
      }
    })

## `Effect.gen` and `Effect.fnUntraced`

Prefer `Effect.fnUntraced` over functions that only return `Effect.gen`.
    
    // ❌ AVOID - Function only wraps Effect.gen
    const fn = (param: string) =&gt;
      Effect.gen(function*() {
        // ...
      })
    
    // ✅ PREFER - Reusable untraced Effect function
    const fn = Effect.fnUntraced(function*(param: string) {
      // ...
    })

## When to Use What

Use `Effect.gen` when:

  * Writing inline effect composition
  * One-off operations that don&#39;t need to be reused
  * Inside other functions already being traced

Use `Effect.fnUntraced` when:

  * Building library implementations
  * Performance is critical (hot paths)
  * Function is called many times per operation
  * Tracing overhead is unacceptable

## `Context.Service`

Prefer the class syntax when working with `Context.Service`.
    
    import { Context } from &quot;effect&quot;
    
    class MyService extends Context.Service&lt;MyService, {
      readonly doSomething: (input: string) =&gt; number
    }&gt;()(&quot;MyService&quot;) {}

<excerpt>citeturn0search1 [wordlim: 200] Crawled: 2 weeks ago; Schema issues no longer carry a `toString()` (Effect-TS/effect#7093), so the Durable Object RPC server renders decode failures through `SchemaIssue.makeFormatterDefault()` like the rest of the codebase.
Schema issues no longer carry a `toString()` (Effect-TS/effect#7093), so the Durable Object RPC server renders decode failures through `SchemaIssue.makeFormatterDefault()` like the rest of the codebase. The `@effect/vitest` record-arbitrary workaround was dropped because Effect-TS/effect#7148 fixed it upstream (#1557).

  * Effect rc.113 API burndown: Replaced the removed MessagePack RPC layer with `SchemaBinary`, migrated sockets to the pull reader and scoped writer APIs, and updated CLI constructors and schema transformations to their rc.113 names. The FastCheck-based `Vitest.asProp` helper was removed; use `Vitest.live.prop` with `arbitrary` options (#1606).

  * Tooling: Shell entry no longer runs the full TypeScript build after dependency and generated-source setup. The shared Effect-utils `otel:profile:setup` task captures the strict setup graph through native devenv tracing and `otelite`; `otel:verify:setup` gates the connected trace shape without a repository-local orchestration module (#1402).

  * Tooling: Unit-test failures now block merges. The `test-unit` job ran `packages/@livestore/webmesh` and `tests/package-common` through `Effect.ignore` on CI, so their failures produced a passing required check. Removing that also restores the intent-layer invariant suite as a real gate on `context/` changes (#1404).

  * Tooling: The DevTools Playwright suite is currently broken (0/15) and carries a declared, expiring quarantine entry instead of an unrecorded `|| echo` wrapper. Its check does not gate merges yet — the quarantine records the failure with a reason, an issue, and an expiry date rather than hiding it (#1489).

  * Tooling: Cloudflare sync-provider failures now block merges. All six `cf-*` matrix cells previously exited 0 on failure, which is why the Durable Object hibernation guards could not gate merges (#1404).

Return the capacity error through the Effect failure channel.

When the capacity condition is met, the direct throw inside Effect.gen becomes a defect. Effect.catch does not handle defects, so #failPoll can be skipped.

Update the capacity check in the Effect.gen flow to return the
PermanentPollError through the Effect failure channel using Effect.fail instead
of throwing it, so the existing Effect.catch path can handle the failure.

@l1shen l1shen changed the title feat(triggers): adopt connector-owned sources and per-event poll runs feat(triggers): adopt connector-owned sources Oct 27, 2026
l1shen added a commit to oomol-lab/open-connector that referenced this pull request Oct 27, 2026
Restore the existing Poll business contract after #790: the 10 affected
providers keep `definitionVersion: 2`, output `events[]`, and build
outputs from the complete event sequence. Source ownership changes must
not split a batch into one Run per event.

Provider configuration, polling/checkpoint logic, Source persistence and
callback handling remain unchanged. The corresponding Open Flow
correction removes the v3 execution and upgrade paths:
oomol-lab/open-flow#160.

Validation:
- `npm run fix-check`, catalog generation and all 21,053 action examples
passed.
- Trigger runtime, provider contracts and shared conformance: 58 tests
passed.
- Runtime package build passed.
- Cross-repository validation passed; all 10 Poll snapshots exactly
match the Open Flow definitions before the architecture change.
- Open Flow root `bun run check` passed before commit.

No deployment was performed. Deploy this correction before switching
Open Flow to the new Source reference protocol.

- Around line 462-463: Update the scenario assertion that checks
`poll.definition.definitionVersion` and the `events` output so it also verifies
the final Poll configuration matches the intended initial configuration,
including settings such as Gmail `search`. Compare configuration state directly
rather than relying on command order or on `LabSession.runSample` results, which
supply sample events independently of the saved Poll configuration.
