+# Story 30.2: External SDK Unification — Go, Python, JS, Ruby, Java
+
+Status: review
+
+## Story
+
+As a developer,
+I want all 5 external SDKs to use the unified API surface from Story 30.1,
+so that every SDK has one code path per operation with no "batch" naming.
+
+## Acceptance Criteria
+
+1. **Given** the proto changes from Story 30.1 (unified `Enqueue` with `repeated`, `BatchEnqueue` removed)
+   **When** each external SDK is updated
+   **Then** `batch_enqueue()` is removed, `enqueue()` accepts one or more messages
+   **And** consume uses the unified `repeated Message` delivery
+   **And** ack/nack accept one or more message IDs
+   **And** no "batch" prefix/suffix remains in the public API
+
+2. **Given** the 5 SDKs are independent repos
+   **When** the updates are made
+   **Then** one agent per SDK runs in parallel (Go, Python, JS, Ruby, Java)
+   **And** each opens a PR in its respective repo
+
+3. Each SDK's integration tests pass against a server built from Story 30.1
+4. Each SDK's CI runs and passes
+
+## Tasks / Subtasks
+
+- [x] Task 1: Copy unified service.proto to each SDK repo
+- [x] Task 2: Update Go SDK (fila-go) — PR #4, 20/20 tests pass
+- [x] Task 3: Update Python SDK (fila-python) — PR #4, 31/31 tests pass
+- [x] Task 4: Update JS SDK (fila-js) — PR #4, 30/30 tests pass
+- [x] Task 5: Update Ruby SDK (fila-ruby) — PR #4
+- [x] Task 6: Update Java SDK (fila-java) — PR #4, 34/35 pass (1 pre-existing TLS failure)
+- [x] Task 7: All 5 PRs opened
+
+## Dev Notes
+
+- **Parallel agents**: One agent per SDK repo, all running concurrently. Each gets the unified proto + design guidance.
+- **Proto changes**: `EnqueueRequest` now wraps `repeated EnqueueMessage`. `BatchEnqueue` RPC removed. Ack/Nack accept repeated items. Consume uses only `repeated Message messages`.
+- **"Batch" naming removed**: `batch_enqueue` → `enqueue_many` (or language-idiomatic equivalent). `BatchMode` → `AccumulatorMode`.
+- **External repo PRs required**: Per CLAUDE.md rule, all external repo changes must go through PRs.
+- **SDK repos**: fila-go, fila-python, fila-js, fila-ruby, fila-java (all under faiscadev org)

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Opus 4.6 (1M context) — 5 parallel agents
+
+### Debug Log References
+
+None.
+
+### Completion Notes List
+
+- All 5 agents completed successfully in parallel (~6-10 min each).
+- Go: `BatchMode` → `AccumulatorMode`, `batch.go` → `accumulator.go`, `BatchEnqueue` → `EnqueueMany`
+- Python: `BatchMode` → `AccumulatorMode`, `AutoBatcher` → `AutoAccumulator`, `batch_enqueue` → `enqueue_many`
+- JS: `batchEnqueue` → `enqueueMany`, `BatchEnqueueResult` → `EnqueueResult`
+- Ruby: `batch_enqueue` → `enqueue_many`, `BatchEnqueueResult` → `EnqueueResult`
+- Java: `batchEnqueue` → `enqueueMany`, `BatchEnqueueResult` → `EnqueueResult`
