… → complete The MGE-potential self-consistency failure (grad(psi)=alpha med 7.1e-2) was fixed on 2026-08-09 by PyAutoGalaxy#564, which replaced the MGE approximation with the analytic BMO (2009) eq. 18 potential — merged outside this prompt's dev flow, so the ledger had gone stale. Re-verified on current main (FD check, med ~1e-9 across tau = 0.5/2/10), recorded to complete/2026/08/, removed the stale planned.md entry, dashboard + index regenerated. lifecycle.py check OK.

Summary
Ledger reconciliation: the
NFWTruncatedSph.potential_2d_fromMGE self-consistency bug tracked bydraft/bug/autogalaxy/nfw_truncated_potential_accuracy.mdwas already fixed by PyAutoGalaxy#564 (merged 2026-08-09, fixes PyAutoGalaxy#563), which replaced the MGE approximation with the exact analytic Baltz, Marshall & Oguri (2009) eq. 18 potential. The fix shipped outside this prompt's dev flow, so the Mind still showed it as open high-priority work.draft/→complete/2026/08/nfw-truncated-potential-accuracy.mdviascripts/lifecycle.py record(rich record + original prompt folded in).## nfw-truncated-potential-accuracysection removed fromplanned.md.complete/index.mdanddashboard.mdregenerated;lifecycle.py checkOK.Verification

main(49115ad):grad(psi)=alphamedian fractional error ~1e-9 (max ~5e-7) for tau = 0.5 / 2 / 10 — the med 7.1e-2 failure the prompt documents is gone. The unit tests the prompt asked for already exist intest_autogalaxy/profiles/mass/dark/test_nfw_truncated.py.No library code changes — this PR touches the Mind ledger only.
