expected_routing_class: proceed

escape_hatch_applied: true
direct_mode_stripped_message: "write an abstract for my paper about quantum error correction at scale"
notes: |
  `[Direct-Mode]` capitalized variant — case-insensitive byte-0 match per protocol doc.
  Strip and proceed.

  Stripped message ("write an abstract...") maps to academic-paper abstract mode via
  Step 1 explicit-intent handling.

  Pass criteria:
  - Capitalized `[Direct-Mode]` accepted as escape hatch
  - Routes to abstract workflow
  - No clarification fires
