About this dataset

SN: migration notes

Internal record of the P6 migration. This is a dated record (2026-10-05) and is not shipped.

Issue: pc-28e.8.21
Parity verdict: frozen-ok against the live public CSV https://postal.datahub.io/sn/sn.csv
Producer: none. The dataset is frozen with no pipeline: block.

Why frozen

Licence-restricted (plan D5, user decision): the postal layer's redistribution licence is unresolved. See .licensing-notes.md. The old builder read a local snapshot of a fedex-agents-prototype CSV, which is not in the repo. The old scripts/ are kept as a provenance record and are not run.

Changes in this commit (orchestrator)

Removed row counts from the descriptor description and the README (standing doc rule).
Removed "see ATTRIBUTION.txt" references: free datasets ship no ATTRIBUTION.txt. The licence disclosure is now inline in the README.
README was the stale "no data yet" placeholder although the live CSV has data. Rewrote it from the old builder's README text, keeping the unresolved-licence caveat.

Open questions

Resolved (user, 2026-10-05): README edits confirmed.
