// adam-batch.mjs — pre-clusters windowed journal entries into coherent failure
// batches before analyst dispatch. Implements MOSS §3.1: "anchored to an
// automatically curated batch of production-failure evidence."
//
// Each batch groups entries by (signal_type, cluster_key) where cluster_key
// follows the same clustering rules as agents/adam.md ## Signal types / ## Process step 4:
//   correction     → tokenized phrase (cross-cwd)
//   retry_loop     → tool
//   weak_agent     → subagent_type
//   tool_error_loop→ fp
//   dead_end       → session
//   edit_churn     → file basename
//   file_reread    → file basename
//   build_loop     → session
//   subagent_dispatch_pattern → subagent_type
//   silent_drift   → active_skills[0]
//   error_after_recovery → (recovered_from, original_fp)
//   correction_free_streak → active_skills[0]
//   clean_recovery → (recovered_from, active_skills[0])
//   task_completed → sorted tool_kinds tuple
//
// CLI:
//   adam-batch.mjs [--input <jsonl-path>] [--min-entries N] [--min-sessions N]
//
// Output: JSON object with `batches` array and `unbatched` count.
