+- **NEW:** System Prompt: Autonomous loop persistence guidance (CLAUDE_CODE_LOOP_PERSISTENT) — Adds timer-invocation guidance for autonomous work loops, including when to continue established work, maintain current PRs, broaden scope before stopping, and require clear authorization for irreversible actions.
+- **REMOVED:** Agent Prompt: Verification specialist — Removed the adversarial verification subagent prompt that required independent builds, tests, browser/API checks, and PASS/FAIL/PARTIAL verdicts without modifying the project.
+- **REMOVED:** Data: Background agent state classification examples — Removed the standalone background-agent state-classification examples data prompt.
+- Agent Prompt: Background agent state classifier — Expands notification-state classification with detailed done/working/blocked/failed boundaries, explicit marker rules, embedded examples, cron/re-poll handling, optional-offer vs delivery-gate distinctions, and lock-screen-oriented `detail`, `needs`, and `output.result` guidance.
