What this pack is
3 contests, 712 people, 247 poll response rows, 960 result rows and 0 money edges, built 2026-09-03.
The cycle phase shown on every contest is computed from the election date and how well that date is known. The corpus carries its own status column; it disagrees with the derived phase on 20 of the 61 contests across all twenty-two countries, so it is carried through but never read.
Money rows and result rows are held off the site at their full grain: the staged corpus is 156 MB. What is published here is the aggregate computed once at build time, and every aggregate states the number of rows it stands for.
Everything known to be wrong or limited

## Elections
- `jpn-hr-2026-02-08`: 第51回衆議院議員総選挙, 2026-02-08, confirmed official from 衆議院 and 総務省.
- `jpn-hc-2025-07-20`: 第27回参議院議員通常選挙, 2025-07-20, confirmed official.
- `jpn-hc-2028`: next Councillors election; 2028-07-25 is official term expiry of the 2022 class and is marked `constitutional_due`. Execution date is not gazetted.
- Next lower-house election is unscheduled because dissolution is possible; no speculative row.
## People
Incumbents only from official 50-on lists. Stable profile IDs are `shugiin-{id}` and `sangiin-{id}`. Party values are official parliamentary groups. Councillors are assigned to the 2025 or 2028 election ID by official term-expiry class. Bios/photos are empty.
The lower-house parser initially missed 笠浩史 because `9giin.htm` has a merged header; he was added from that official row. Final lower-house party counts exactly sum to 465. Upper-house official count is 247, with one vacancy.
## Money
Empty on purpose: Sōmushō political-funds reports are PDFs. No yen inferred from news. Do not fuzzy-match future money data by name.
## Polls
Long format cabinet/party tables only: Yomiuri 7 waves, Jiji 5, Asahi 2, NHK 2 (cabinet only). `moe` is blank. July Yomiuri sample_n is blank because the retrieved method note was truncated. Some Jiji undecided values are omitted where the article did not print them.
No git. `_raw/` and `results.csv` are ancillary workspace files, not part of this requested seven-file pack.
