About this dataset

Mexico (MX): migration notes

Internal record of the P5 migration. This is a dated record (2026-10-05) and is not shipped in the zip.

Issue: pc-28e.7.36 (open, deferred)
Producer: none written. The descriptor keeps pipeline: producer: custom with refresh disabled, and the data stays as harvested from the live zip in 09d7c89.
Parity: not run (no producer).

Why it stays on live data

The SEPOMEX downloads return 403 from our egress, so scripts/fetch_sepomex.py can't fetch the source.

Decisions

Decision	By	Basis
Defer under D1: stay on live data	User, 2026-10-03	Source unreachable from our egress

Open questions

Revisit with an MX/US egress. The P8 refresh runner needs one too.

Provenance

Written 2026-10-05 from docs/parity/p5.md (batch sign-offs) and the bd notes on pc-28e.7.36.
