Move sha256_hex out of orchestrator/supervisor/util.py to the root bot_bottle.util (it's a generic string hash, not supervise-specific), and have Proposal.new take the proposed file contents and compute current_file_hash itself instead of every caller passing sha256_hex(proposed_file). Every call site set current_file_hash to the hash of the proposed file, and nothing reads the field except the DB round-trip (schema + _row_to_proposal + from_dict, all untouched), so folding the hash into the factory is behavior-preserving and removes the boilerplate. Callers now pass just the file; the orchestrator no longer imports sha256_hex at all. Full unit suite green (2243). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
