"""Ask Claude to turn free-text contact form messages into CRM lead fields, then check that every field is
in the message and that no sender is entered twice, before anything would go into a CRM.

Claude does the work: for each message it returns the sender's name, company, need and timing, and for each
field the exact words in the message that say it. Plain code then checks the work: every quote must be in the
message word for word, a name or company must be written in its quote, every number and name in a need or a
timing must be in its quote, and the sender's form email must not already be in the CRM or in an earlier
message. The check is ordinary Python, never a second AI call.

    export ANTHROPIC_API_KEY=...            # or LOOP_ANTHROPIC_API_KEY
    python3 contact_form_to_leads.py                                          # live run, writes the files below

    add --strict to exit 1 when any answer is caught (for a scheduled job); add --out <folder> to write elsewhere

Everything the script writes goes to --out (default: the folder this file is in):
  contact_form_to_leads-answers.json   every request and answer (model id, date, prompt, raw answer, tokens)
  contact_form_to_leads-leads.csv      one row per message: the outcome of the check and the fields
  run-view.html                        the run, played one message at a time
A --plant-error run writes contact_form_to_leads-planted-leads.csv and run-view-planted.html instead, and
never touches the clean run's files.
