Part of erp#65 (phase 1). Ledger grammar "thirdparty complete" gets its
op: allowlisted non-ledger fields, per-field diff read-back. Contacts
are born idempotent (dedupe by email then name). Promote ops wired both
targets, offline stub tests, SKILL.md workflows, KM dossier manifest
(unsigned-contract truth fix + EIN-to-collect note).

The pack (manifests, prelude, runbook, verify-provenance.py PoC) lived
only in an ephemeral session scratchpad while erp#41/#42/#43/#44 now
reference it as fixtures and the prod replay is still pending. 36/36
provenance checks were green at rehearsal time; PDFs are re-fetchable
via arcodange-email-ingest (documented in the pack README).
