The fictional chart's 2026 return moves 08:48:04 -> 08:41:55 (PyJHora within
0.09 min); the annual Lagna crosses from Taurus 1.3 to Aries 29.6 and the
current-year lord becomes Jupiter. Not in the quick gate, so the BUG-1220
acceptance missed it. Full Python suite: 62 failures before and after,
identical lists.

The natal Sun target came from compute_chart_data while the solver iterates
on _get_sun_lon_jd (swe sidereal flags); the frames differ by up to ~17",
moving the return by up to ~7 minutes. The annual chart was also cast at the
truncated minute. Ports upstream yinduzhanxing 7cc6425d / 46ed9399 (these two
hunks only). PyJHora reference: 3 cases within 0.03 min. 243 public-figure
annual charts: annual Lagna changes 13, year lord 11, Mudda first lord 0.
v5 77 cases identical to 3c27c38e; consult goldens re-captured byte-identical.
