About this dataset
Bangladesh (BD): 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.7.5 (open, stays on live data)
- Producer: none written. The descriptor keeps
pipeline: producer: customwith refresh disabled, and the data stays as harvested from the live zip in09d7c89. - Parity: not run (no producer).
Why it stays on live data
- There are no builder scripts:
scripts/only haspublish_r2.py. Nothing records how the live CSV was built. - Rule (user, 2026-10-03): no producer from scratch for a dataset with no builder scripts.
Decisions
| Decision | By | Basis |
|---|---|---|
| No producer; stay on live data | Standing rule (user, 2026-10-03) | No builder scripts to port |
Open questions
- None for P5. A producer would be new work (a new source and licence check), so it needs a user decision.
Provenance
Written 2026-10-05 from docs/parity/p5.md (batch sign-offs) and the bd notes on pc-28e.7.5.
