"""
Source-database manifest for the staging load (migration plan step 1).

Exclusions here are deliberately conservative: only tables that are either
(a) confirmed empty (0 rows — nothing is lost by skipping them) or (b) have
rows but are structurally not customer/business data (mail-merge document
templates, materialized Access query results) are excluded. Anything with
real rows and an ambiguous purpose (e.g. PROPANO, datosfreak, pagos email)
is loaded into staging anyway — the reconciliation pass decides what to do
with it, per the migration plan's "don't guess the rule up front" principle.
See PLAN.md (repo root) for the full rationale per table group.

Environment note: this project moved from Windows to macOS. The original
extraction path (pyodbc + the Windows Access ODBC driver in extract.py) does
not work on macOS; extraction is being reworked to use mdbtools
(`brew install mdbtools`). This SOURCE_ROOT points at the macOS location of
the four Access source files.
