…xes 0923 vs 0922 tile names) The baked possum2caom2 dated from Aug 2025 (pre-healpy switch), so the image still ran astropy_healpix and named boundary tiles like tile 6514 as 0923 instead of 0922. possum2caom2@main now uses healpy; CD builds with no-cache so this rebuild re-pulls it fresh.

Adds a dated comment above the
possum2caom2install inpossum_prefect/Dockerfileto trigger a rebuild that picks up the currentpossum2caom2@main.Why
The image's baked
possum2caom2dated from Aug 2025 (v1.15.2), predating the switch fromastropy_healpixtohealpy. With the old library, HEALPix boundary tiles get the wrong coordinate string in their filenames — e.g. tile 6514 is named…0923-0335…instead of…0922-0335….Root cause:
astropy_healpix.healpix_to_lonlat(6514)returns RA = 140.625 exactly → the minute rounds up to 23;healpy.pix2angreturns 140.6249999… (1 ULP lower) → rounds to 22.possum2caom2@mainnow uses healpy, so a fresh rebuild produces the correct0922.Notes
@mainis intentionally kept (no version pin); CD builds withno-cache: true, so the rebuild re-pullspossum2caom2@mainfresh.fix:).After merge
local-poolworker at the new image tag and restart it.…0923…tiles already in the archive (the pipeline's_renameskips already-renamed files).
