make_mag_summary crashes with NameError: full_classification referenced before assignment

[DanielSprockett]

Bug

resources/scripts/make_mag_summary.py crashes immediately with:

NameError: name 'full_classification' is not defined

Location

In the per-bin loop (current main, resources/scripts/make_mag_summary.py):

tax_entry = tax_map.get(
    bin_name, (parse_gtdbtk_classification(''), '', '', ''))
if bin_name not in tax_map or not str(full_classification).strip():
    missing_tax.append(bin_name)
tax_dict, full_classification, msa_percent, gtdbtk_warnings = tax_entry

full_classification is referenced in the if condition one line before it is unpacked from tax_entry. This fails on every invocation that reaches this code path, independent of input data — it blocked Stage 2 completion (make_mag_summary -> rename_mags) on an arm where every upstream stage (CheckM2, GTDB-Tk, GUNC, Binette) had already produced valid output for all samples.

Fix

Move the unpacking line before the if check:

tax_entry = tax_map.get(
    bin_name, (parse_gtdbtk_classification(''), '', '', ''))
tax_dict, full_classification, msa_percent, gtdbtk_warnings = tax_entry
if bin_name not in tax_map or not str(full_classification).strip():
    missing_tax.append(bin_name)

Context

Hit on the WF27_MGX_LAI arm, pinned at commit 697daa1. That short SHA does not currently resolve via the GitHub API against this repo, which may mean it's no longer reachable from any branch (rewritten history?) — worth checking separately. Patched locally on the running clone to unblock; filing here so it's fixed upstream for other arms.
