batchTrigger and batchTriggerAndWait (and the by-id and by-task variants) now offload any per-item payload over 128KB to object storage before sending, the same way single trigger and triggerAndWait already do, so a big batch no longer blows past the API body limit. Every trigger and batch item also reports its pre-offload serialised payload size on the request options, so a consumer can tell how big a payload is without fetching the offloaded application/store reference.

5-54: 📐 Maintainability & Code Quality | 🔵 TrivialGood edge-case coverage; consider also testing the actual offload branch.
Coverage for empty arrays, small pass-through, multi-byte sizing, pre-offloaded items, and missing-payload items is solid. However, there's no test exercising the branch where a payload actually exceeds the offload threshold and
conditionallyExportPacket/exportPacketruns. Per prior guidance in this repo, stubbingApiClientmethods (e.g.apiClient.createUploadPayloadUrl) withvi.fn()is acceptable for unit tests exercising in-memory/call-counting logic, so this could be added without violating the "no mocking, use testcontainers" policy for integration tests.
[recommended_refactor]Based on learnings, "for unit tests that exercise pure in-memory logic ... it is OK to stub collaborators such as

prompt: You are auditing this PR for drift against `.claude/REVIEW.md`.
## Context
`.claude/REVIEW.md` is the repo's source of truth for what AI / agent code reviewers should treat as critical findings (rolling-deploy safety, hot-table indexes, recovery-path queries, testcontainers usage, Lua versioning, etc.). It is consumed by review agents to calibrate severity. If REVIEW.md goes stale, every future agent review degrades.
## Strategy — read this first
You have a hard turn budget. Spend it on signal, not coverage. The audit is allowed to miss things; it is NOT allowed to time out.
1. Read `.claude/REVIEW.md` once, in full.
2. Run `git diff origin/main...HEAD --name-only` to get the list of changed files. Do NOT read the diff content yet.
3. Scan the file-list for relevance to REVIEW.md scope. Relevance signals: changes to Prisma schema, Redis / queue / Lua code, hot tables, recovery / restart loops, new packages, deletions of paths REVIEW.md cites. Skim everything else.
4. Open at most **5 files** total — only the ones most likely to surface a real signal. If nothing in the file-list looks relevant to any REVIEW.md rule, do NOT read any files; go straight to the verdict.
5. Form a verdict and stop. Do not exhaust the turn budget exploring.
Large PRs (>50 files changed) are a strong signal to be MORE selective, not more thorough. Pick 3-5 files at most.
## What to look for
- **Stale references** — does any REVIEW.md rule cite a file, directory, function, table, Prisma model, or package name that has been removed or renamed in this PR (or is already gone from `main`)?
- **Contradictions** — does code in this PR clearly violate a current REVIEW.md rule? (Don't re-review the PR. Only flag if REVIE...

prompt: You are reviewing a PR to check whether any agent instruction files need updating.
In this repo:
- Root shared agent guidance lives in `AGENTS.md`.
- Root `CLAUDE.md` is only a Claude Code adapter that imports `AGENTS.md`.
- Subdirectories may still have scoped `CLAUDE.md` files.
- `.claude/rules/` contains additional Claude Code guidance.
## Your task
1. Run `git diff origin/main...HEAD --name-only` to see which files changed in this PR.
2. For each changed directory, check the applicable instruction files: root `AGENTS.md`, any `CLAUDE.md` in that directory or a parent directory, and relevant `.claude/rules/` files.
3. Determine if any instruction file should be updated based on the changes. Consider:
- New files/directories that aren't covered by existing documentation
- Changed architecture or patterns that contradict current agent guidance
- New dependencies, services, or infrastructure that agents should know about
- Renamed or moved files that are referenced in an instruction file
- Changes to build commands, test patterns, or development workflows
## Response format
If NO updates are needed, respond with exactly:
✅ Agent instruction files look current for this PR.
If updates ARE needed, respond with a short list:

Learning: In the triggerdotdev/trigger.dev codebase, webhook URLs are not expected to contain embedded credentials/secrets (e.g., fields like `ProjectAlertWebhookProperties` should only hold credential-free webhook endpoints). During code review, if you see logging or inclusion of raw webhook URLs in error messages, do not automatically treat it as a credential-leak/secrets-in-logs issue by default—first verify the URL does not contain embedded credentials (for example, no username/password in the URL, no obvious secret/token query params or fragments). If the URL is credential-free per this project’s conventions, allow the logging.

Learning: When handling Prisma error P1001 ("Can't reach database server") in TypeScript, don’t assume a single error shape. Prisma can surface P1001 via two different error classes/fields: `PrismaClientKnownRequestError` exposes it as `err.code === "P1001"` (common during mid-query connection drops), while `PrismaClientInitializationError` exposes it as `err.errorCode === "P1001"` (common on client startup failure). Therefore, predicates should use `err.code === "P1001" || err.errorCode === "P1001"`. Do not flag `err.code === "P1001"` as “unreachable/never matches,” as it is expected in production.

Learning: When handling Prisma errors for P1001 ("Can't reach database server"), do not assume it only appears under a single property name. Prisma may surface P1001 via either `PrismaClientKnownRequestError` (`err.code === "P1001"`, e.g., mid-query connection drops) or `PrismaClientInitializationError` (`err.errorCode === "P1001"`, e.g., client startup connection failure). To reliably detect the condition, check `err.code === "P1001" || err.errorCode === "P1001"`, and avoid review rules that would incorrectly flag `err.code === "P1001"` as unreachable/never-matching.

Learning: In triggerdotdev/trigger.dev, within `dashboardLoader`/`dashboardAction` (or similar context resolver code) whenever you resolve an organization ID from an organization slug for RBAC/enterprise authorization scope, always read from the primary Prisma client (`prisma`), not `$replica`. Using `$replica` can hit replica-lag and cause the RBAC lookup/authorization to run without the correct org scope (bypassing intended role enforcement). Implement the slug→org lookup with `prisma.organization.findFirst(...)` (or equivalent primary-client query) and add an inline comment documenting why the primary client is required (replica lag could lead to unscoped RBAC checks).

Learning: In TypeScript, it’s valid to `import { type X }` and then use `typeof X` in a type-only position, e.g. `type Alias = z.infer<typeof X>`. The `type` modifier suppresses the runtime import, but the type checker still has the full exported type so `z.infer<typeof X>` can resolve correctly. In code reviews, don’t flag this as a TypeScript compile error as long as `typeof X` is used in a type context (e.g., with `z.infer`, `type` aliases, generics), not as a runtime value.

Learning: In this repo’s trigger.dev codebase, the “never mock — use testcontainers” guideline should only be applied to integration tests that talk to real external services (e.g., Redis, Postgres, S2). For unit tests that validate in-memory logic (e.g., deduplication/cache behavior in StandardRealtimeStreamsManager and similar module-boundary call counting), it is allowed to use Vitest mocks like `vi.fn()` and to stub/mock `ApiClient` objects to count calls or simulate in-process collaborators. Do not flag `vi.fn()`-based mocks as policy violations in these unit-test scenarios; reserve the rule for true external-service integration tests.

For unit tests that exercise pure in-memory logic (e.g., cache semantics) it is OK to stub collaborators such as `ApiClient` using Vitest (`vi.fn()`) to assert call counts or control behavior. Do not flag `vi.fn()`-based `ApiClient` stubs in unit tests as violations of the testcontainers policy.

If an interface is being used as a behavioral contract for collaborators to implement (e.g., method-shape interfaces that define required behavior, such as `BackpressureLogger` / `BackpressureSignalSource` in `apps/supervisor/src/backpressure/backpressureMonitor.ts`), keep it as an `interface` and do not flag it as a type-alias-vs-interface violation.

Learning: In this codebase, outbound raw `fetch` calls should typically rely on Node/undici’s default request timeout (about ~300s) rather than adding a per-call `AbortController` + `setTimeout` wrapper inside individual functions (e.g. in files like `apps/webapp/app/models/vercelIntegration.server.ts`). During code review, do not flag the absence of a per-call timeout on a single `fetch` as an issue; if per-call timeouts are needed, they should be implemented via a codebase-wide convention (e.g., a shared fetch wrapper or documented pattern) rather than ad-hoc per-function changes.

Learning: In this repo’s Vitest setup, `vitest.config.ts` uses `globals: true`, so identifiers like `vi`, `describe`, `it`, and `expect` are available as globals in Vitest test files. During code review, do not flag missing `vi`/`describe`/`it`/`expect` imports as a runtime error or correctness issue when they’re used in `*.test.ts/tsx` or `*.spec.ts/tsx` files. Explicit imports are still preferred for consistency, but they’re not required for runtime behavior.

Learning: When reviewing code in `packages/trigger-sdk/src/v3`, treat `tasks.triggerAndWait()` and `tasks.batchTriggerAndWait()` as real exported APIs. They are defined in `shared.ts` and re-exported via the `tasks` object in `tasks.ts`, and they take the task ID string as their first argument (not a task instance). This is distinct from the instance methods `yourTask.triggerAndWait()` and `yourTask.batchTriggerAndWait()`. Do not flag calls to `tasks.triggerAndWait()` or `tasks.batchTriggerAndWait()` as non-existent or incorrectly invoked.

Learning: In the Trigger v3 session resume/streams logic, ensure session resumption uses sequence cursors rather than timestamps. Specifically: for each turn-complete control record written to `session.out`, include a `session-in-event-id` header whose value is the committed-consume cursor (`session.in.lastDispatchedSeqNum`). On boot/resume, scan `session.out` for the latest turn-complete record, read the `session-in-event-id` header, and seed the `sessionStreams` manager for `.in` using both `lastSeqNum` and `lastDispatchedSeqNum` so previously processed user messages are not replayed. Do not use `setMinTimestamp`/`lastOutTimestamp` for resume ordering in this flow.

Learning: In the Trigger SDK (v3) when making raw `fetch` calls to the Trigger API (including override paths such as `createChatStartSessionAction`), set the request headers to match `ApiClient`: `Content-Type`, `Authorization`, and `x-trigger-source: "sdk"`. Also forward the current preview branch by setting `x-trigger-branch` to `apiClientManager.branchName`. Prefer using the shared `overrideRequestHeaders(accessToken)` helper instead of manually constructing headers, so requests route correctly to preview environments.

Learning: In `packages/trigger-sdk` (Trigger.dev SDK), `logger.warn` (and other SDK logger methods) should route to the Trigger.dev structured logger sink, not to `console.warn`. In SDK tests, `vi.spyOn(console, "warn")` (or similar console spies) should only be used to suppress stray console output; reviewers should not suggest asserting on `console.warn` spies to verify SDK-internal warning/fallback log behavior. Use the SDK’s structured-logger outputs/capture approach instead of console spies.

Summary
batchTriggerandbatchTriggerAndWait(and the by-id and by-task variants) now offload any per-item payload over 128KB to object storage before sending, the same way singletrigger/triggerAndWaitalready do since #3785. A batch of large items no longer inflates the request body past the API limit.Design
Both the array and streaming batch paths funnel through
executeBatchTwoPhase, so offloading happens once there: each item is measured, then offloaded through the existingconditionallyExportPacketwhen it crosses 128KB, with bounded concurrency so a big batch doesn't fire an unbounded number of presigned PUTs.Because items are offloaded before the request, SDK batches arrive as small
application/storereferences, so the server-side inline offload during item ingest (parallelised in #3777) mostly no longer fires for them. Every trigger and item also carries its pre-offload serialised size asoptions.payloadSize.This is part 1 of 2 in a stack made with GitButler:
