Repair an inconsistent solar-coordinate archive workflow
A solar-observation catalogue uses the supplied scientific package to attach coordinate objects to a table before archiving the catalogue for later analysis. The coordinates describe a short sequence of features observed from changing locations. Object construction and the in-memory analysis are valid, but the archive/reload workflow does not yield a catalogue that can be reused consistently in the same downstream analysis.
Reproduce the problem, inspect the source and public workflow, and repair the implementation so that valid solar-observation catalogues retain their scientific meaning through supported archive workflows. The repair must generalize beyond the supplied catalogue. Do not replace scientific objects with fixed outputs, special-case the supplied data, or change the public reproduction to hide a failure.
Work only under this task directory. The evaluation environment is Linux and
has no network access. You may modify files under source/; do not modify the
task statement, reproduction, fixtures, workflow, or evaluation infrastructure.
Run the public smoke test with:
python reproduce.py
The command returns 1 when the untouched source reproduces the scientific
archive failure, 0 after a successful repair, and 2 for a runner or
environment failure.
