Concurrency automation templates

A work queue with both halves built for real: an intake that puts refund requests on a workspace queue one at a time, and a worker loop that takes them off, decides each one, and records Successful or Failed against it. Items are encrypted with an AES key from your vault before they leave the robot, so the Admin Console keeps the history of every item without ever being able to read one. Cut a single wire and the two halves become an intake you can schedule and a worker you can run on any number of robots.

Checks 200 shipment tracking numbers on a public carrier tracker using eight parallel workers pulling from a shared in-memory queue. Reads the tracking list straight from the carrier's bulk page, scrapes status, latest event and ETA for each shipment, and writes a full status CSV plus an exceptions-only CSV covering customs holds, failed deliveries and delays. No login required.

Verifies insurance for every appointment on a clinic's eligibility worklist, running the payer checks on nine parallel browsers instead of one at a time. Signs in, reads the worklist, fans out into workers that each claim an appointment from a shared queue, click its eligibility check and read the coverage answer. Writes a full status CSV plus a coverage-problems CSV listing the lapsed and not-covered patients the front desk has to chase.

Demonstrates parallel browser automation using Fork Branch and Memory Queue. Creates multiple concurrent browser instances that dequeue items from a shared queue, navigate to e-commerce websites, and take screenshots simultaneously.
