### Task Summary Two messaging-layer helpers under `amber/src/main/scala/org/apache/texera/amber/engine/architecture/messaginglayer/` lack dedicated specs: - `AmberFIFOChannel` — per-channel FIFO/exactly-once enforcer with stash + holdCredit + portId. - `CongestionControl` — TCP-style sliding-window send queue with slow-start, ack-window adjustments, and resend after `resendTimeLimit`. Add unit tests covering `acceptMessage` (in-order / duplicate / ahead-of-current / drain after gap fill), `take` / `hasMessage`, the `holdCredit` and stash size accessors, `enable`/`isEnabled`, the `setPortId` / `getPortId` round-trip, and the `CongestionControl` ack-window math (slow-start vs. linear, timeout halving) plus `enqueueMessage` / `getBufferedMessagesToSend` / `markMessageInTransit`. ### Task Type - [x] Testing / QA -- This is an automated message from the Apache Git Service.
