Layer 2 of the import design (see the memory + scratchpad/IMPORT-PLAN.md): a
SITE-SPECIFIC reference loader that maps WJ's classic-ASP schema onto the
maintained, schema-agnostic IMPORT-API contract. Other sites copy the pattern
against their own source DB; nobody runs this loader as-is.
Harness (scripts/site_imports/wjf/harness.py): builds the app against the
current DATABASE_URL (point it at a throwaway import DB), mints an unscoped
admin PAT in-process, and drives the real import endpoints through the app test
client with Authorization: Bearer + X-Import-Mode - exercising the same
routes/authz/validation an HTTP client would, no running server needed.
Read-only pymysql access to the three scratch source DBs; legacy-id -> new-id
crosswalks persist to JSON so a crashed run resumes and later stages resolve FKs.
Stages implemented + verified idempotent against a fresh scratch target
(shopdb_flask_import): reference (vendors 46, businessunits 13, operatingsystems
11) and employees (directory 415, re-run updated-not-duplicated). Remaining
stages (models, applications, assets hub + crosswalk, dependents, network, usb,
verify) are stubbed with the same shape; README documents the adoption playbook.
idmap.json is generated state (gitignored).
