mikkeli 4fd56a12fd 274: provenance document for the roster and transect page
Records where each number came from, which are derived rather than
measured, and which were corrected by hand against reality.

Covers the eight sources and what each does and does not give; the
kilometre datum and why it is not official KP; the two methods used to
position structures (sequence alignment on length, watercourse crossings
as anchors) and where each is unreliable; the 250 m reverse-geocode sweep
that produces the district bands.

Two sections matter most for anyone picking this up later. "Human in the
loop" lists every correction that came from signs, satellite imagery or
knowledge held by no dataset — the 十三里 plate, the ホルカクルキ Ainu
gloss, モトツ橋 as a sheltered span, the 登川 community shift, and the ten
entries found by hand that OpenStreetMap lacks entirely. "Errors found
and fixed" records the pipeline's own failure modes, including the
duplicate-name coordinate bug and the 穂高トンネル 1991 m / 1991 collision.

Named 274-method.md for now; intended to become 274-dev.md once the
current roster file is renamed.

WIP songs

Unless explicitly noticed in the file, the 'WIP' status applies to the whole song as a musical capsule.
This means however it might not seem like, a song has its lyrics completed if the file doesn't say otherwise. Yes.
