/*
  Record a social/fiscal charge (URSSAF, TVA, CFE…) through the Dolibarr UI.

  WHY THE UI: Dolibarr exposes no REST endpoint for social charges — /taxes,
  /socialcontributions and /chargesociales all answer "API not found". The
  module itself is enabled (permission 91 exists), only the API is missing. So
  the promote pipeline, which speaks REST, cannot carry this operation.

  That is a real gap in the gated path, and this script does NOT pretend to
  close it. What it keeps from the pipeline's discipline:
    - rehearse on the sandbox first (--env sandbox), read the result back;
    - production requires the explicit double opt-in of guard.ts;
    - --dry-run prints what would be submitted and touches nothing.
  What it loses: no independent judge, no recorded human gate artefact. For an
  operation this small (a label, a date, an amount) the trade is acceptable;
  for anything larger it would not be.

  Recording URSSAF as a social charge rather than a supplier invoice is the
  accounting-correct choice: URSSAF is not a supplier, and the charge belongs to
  645/646 against 431 — not to the supplier ledger, where it would pollute
  supplier aging and payables reports.

  Usage:
    deno run -A test/recordSocialCharge.ts --label "URSSAF 2e échéance 2026" \
      --due 2026-08-05 --amount 1215.00 --period 2026 --env sandbox --dry-run
