The background-task change repeated its lifecycle design across implemented RFCs, package READMEs, JSDoc, test commentary, and model-visible schemas. That repetition obscured the contracts that maintainers must preserve and added avoidable prompt tokens.
Rewrite the implemented RFCs around the current design, keep authorization, exact-owner cleanup, wait/abort ordering, producer quiescence, and teardown-failure guarantees at their owning surfaces, and remove peer surveys, review history, control-flow narration, and emphatic restatement.
Shorten the task and subagent schema wording, synchronize the bilingual tool cookbook, and regenerate the config, service, RFC, tool, and replay snapshot derivatives. Runtime behavior is unchanged; test edits update prose-only assertions and descriptions.
Bring PR #219 onto current master before re-evaluating review findings so fixes are tested against the code that would actually land.
Resolve generated catalogs by regeneration, preserve the new ACP tool-schema sidecar format while refreshing affected snapshots keylessly, and update the newly paired Chinese adding-a-tool document to match the background-task guidance. This keeps generated and bilingual artifacts authoritative instead of choosing one conflict side blindly.
