Usage:
  anchor-doctrine-to-ledger.sh --ledger-dir <path> --receipt <path> [--tag <text>]

This script ingests an external receipt (typically produced by vm-cloud or other tool)
into vm-ledger, and records a local audit note.

Required:
  --ledger-dir   Path to vm-ledger directory (the repo root or ledger data dir expected by ledger-cli)
  --receipt      Path to a receipt JSON to ingest (verbatim)

Optional:
  --tag          Free-form tag to include in the local audit note

Example:
  ./80-automation/scripts/anchor-doctrine-to-ledger.sh \
    --ledger-dir /Users/sovereign/vm/vm-ledger \
    --receipt /Users/sovereign/vm/vm-cloud/outputs/receipts/<file>.json \
    --tag "doctrine update"
