A 429 reached the worker as a plain message, the status code and Retry-After having been discarded, so it was treated as an item failure: charged as an attempt, retried on its own, and made to wait (attempts + 1) minutes with nothing bounding that. One rate limit therefore reduced every later request to a single chunk and walked straight back into the limit. Both now reach the worker. A rate limit is deferred rather than charged: attempts is left alone, the deferral is counted in the new queue.rate_limit_deferrals column, and the item waits as long as the provider asked. Other failures wait 30 seconds doubling to a 15 minute cap. Only a retried item is separated from its batch now. Issue: #69

📝 WalkthroughWalkthroughThe PR adds provider rate-limit detection and Merge Risk: 🟡 Moderate · up to The change defers rate-limited work and preserves provider-requested cooldowns, but requests may still resume before Retry-After expires, potentially retriggering throttling and delaying queue progress. The test also does not verify elapsed cooldown time, so this should be fixed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

The cooldown capped every wait at 300 seconds while items were deferred for as long as an hour, so the worker came back early, had the pull refused, and charged a deferral to unrelated rows. Also read the test's request body in full, which read() can return short, and tag a code fence for markdownlint.

17-19: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winStrengthen the test for the full provider cooldown.
Retry-After: 3is below the former 300-second cap, so this scenario cannot detect a regression that shortens larger provider waits. The assertions also inspect log text and request shape, but the fake provider records no request timestamps, so they do not prove the actual wait interval.Add an elapsed-time assertion and a separate case that validates a value above 300 seconds by inspecting the persisted deadline instead of sleeping for the full duration.

Reviewed: rate-limit handling logic, backoff/cooldown math, and SQL migrations all check out. CodeRabbit's three findings (cooldown truncating the provider's Retry-After, a short-read in the test's fake HTTP server, a markdownlint fence) were fixed in-PR. Renumbered the new TAP test (008 -> 010) to avoid a collision with PR #70, which merged first and took 008/009.
