The board line's cost field had two specifications and one of them was this
script. `--help` prescribed a versionless `sonnet/xhigh`; the global model
rubric it points at spells the model `Sonnet 5 / xhigh`. A session following
either was correct by its own source, so the field drifted with nobody making
a mistake. Measured across a real 44-repo tree: 14 board lines carrying eight
distinct strings, and not one of them the form documented here - the only
spelling nobody used was ours.
The help now prescribes the rubric's, which is also what most lines already
carry. The parser is untouched and stays lenient: it reads to `;` or `-->` so
the rubric's spacing survives, and the fixtures still vary the spelling on
purpose to pin that. Read-side leniency was never the defect; it is what makes
a documentation-only fix sufficient.
No normalization at read, deliberately. Board lines are rewritten every session
by convention, so an unambiguous spec self-heals the existing lines in about one
session per active repo - mapping variants would be permanent code migrating
data that migrates itself. Nothing compares the field mechanically today either:
KOST is a display column and the board sorts on a numeric bucket key, so the
defect was real but latent. Two checks (28 -> 30) pin the documented form,
red first, because cleaning the data cannot fix a spec that regenerates the
divergence every session. Validation at write has no write path to attach to:
nothing in this repo emits a board line outside the fixtures.
