The file called 274-dev.md was never dev notes — it was the roster. It now sits alongside 274-lookup.csv and 274-lookup.geojson under the same stem, since all three carry the same table. 274-dev.md -> 274-lookup.md the roster, source of truth 274-method.md -> 274-dev.md how it was built References updated: DOC in 274-romaji.py, the roster path in 274-transect-build.py, and the docstrings in both. 274.md now links to the dev notes and the reference tables separately; each of the two docs links to the other and back to the song page. Titles follow: "274 - reference tables" and "274 - how the roster was built". Verified after renaming: 274-romaji.py --check reports no changes and 274-transect-build.py rebuilds 168 entries, so neither script lost its input.

"""Rebuild the data payload inside 274-transect.html from 274-lookup.md.
|
|
|
|
The HTML is self-contained: it carries its data in a <script id="data"> block so
|
|
it opens straight from disk. This script re-reads the roster table out of
|
|
274-lookup.md, joins the route line and district bands, and writes the payload back
|
|
into the HTML in place. The page's markup, CSS and JS are left untouched.
|
|
|
|
python3 274-transect-build.py
|
|

Inputs : 274-lookup.md (roster, source of truth), 274-route.json, 274-districts.json
|
|
Output : 274-transect.html (data block replaced)
