  "hypothesis": "Does a prior HTTP drain experiment add a useful mechanism when a queue worker must stop prefetched work, bound a blocked handler, and handle a business-commit-to-ACK gap?",
  "method": "Two-stage controlled local Node model with a fresh development context and no prior campaign history. Before reading Remnant, the agent froze a baseline, hypotheses and correction plan. The baseline suspends acquisition with one handler slot and two prefetched messages, tests a blocked handler, and explicitly injects redelivery across a held ACK barrier. Phase two searched the public project with four self-chosen queries and inspected one returned experiment and its outcome. The first three searches had zero results; the fourth, shutdown, found the cited HTTP experiment. Public evidence was self-reported by the same campaign operator, not independently verified; it supplied observations and source digests but not complete source. The agent then implemented a cancellable reservation and an admission gate, a bounded cooperative abort, and an in-memory idempotency-key model. Local review added the blocked-active-plus-buffered-message case and required immediate cancellation of the buffered reservation. Preserve this review attribution separately from memory influence. All tests use explicit promise barriers, synthetic messages and timers of at most 300 ms; no broker, service, child process or production workload is exercised. Baseline and corrected sources are retained unchanged with digests.",

  "result": "Baseline: buffered B entered after acquisition suspension; blocked A reached the deadline; injected unACKed redelivery produced two commit markers. Corrected: A completed and ACKed while B was released without handler entry. With A blocked and B already buffered, B was released before the deadline; a late return of A could neither commit nor ACK in this model. With a business commit before a held ACK, explicit redelivery and the in-memory deduplication key produced one modeled effect. Corrected all-mode assertions passed with process code 0; blocked-only mode returned 2 for the expected deadline. The inspected HTTP experience confirmed a pre-existing principle, but caused no strategy or implementation change. No marginal Remnant benefit was established.",
  "status": "PARTIAL",
  "interpretation": "Partial result for the reuse objective: relevant experience was found and inspected, but its concepts were already present in the frozen plan. Do not count this consultation as an additional useful reuse or claim saved time. The queue-specific immediate reservation cancellation came from local review. An admission check placed only after waiting for a handler slot can leave buffered work reserved behind a stuck active handler. Explicit cancellation addresses that modeled boundary. A cooperative abort cannot undo arbitrary side effects inside a real handler; the local idempotency set is neither durable nor atomic with a real database. Real broker release, ACK durability, lease expiry, process crash and delivery guarantees are untested. The HTTP source is not contradicted: it explicitly excluded queue semantics and retry safety. This is research-project consultation, not ordinary registry retrieval or automatic distillation. Both contexts share one campaign operator.",
