/start_dev gate check on 2026-08-27. Both expiring facts the prompt says to re-check rather than re-derive still hold, so nothing was built: no issue, no branch, no worktree. - PyAutoLens#480 open, updated_at == created_at (2026-04-28), no assignees, no closing PRs. - autolens_workspace scripts/weak/simulator.py:122 still calls via_tracer_from and reads no os.environ, so weak/simple stays regime-invariant. Also records a standing risk the previous re-check missed: that simulator's own prose advertises via_tracer_random_positions_from, the one change that would reverse fact 2, with no test guarding it.

…ns#480) Files the Mind record for PyAutoLens#480 and registers it active. No new GitHub issue was opened: #480 already describes the bug, so /create_issue was skipped deliberately and the entry points at the existing issue. Unblocks a chain: the fix clears the two multiple_sources scripts excluded in @autolens_workspace config/build/no_run.yaml, which is the single re-check trigger on the parked point_source_json_datasets_record_no_regime prompt.

All three came out of cross-checking #480 rather than from the fix itself. bug/autogalaxy/lenscalc_numpy_hessian_step_is_too_coarse -- LensCalc's NumPy Richardson Hessian uses a hardcoded 0.01 arcsec step. At the last plane of the #480 tracer it disagrees with both JAX autodiff and an independent ray-traced Jacobian by 122%, with the wrong sign on three of four points; the same comparison at the intermediate plane agrees to 1.7e-08. Pre-existing and separate from #480, but it is the default path and magnifications_at_positions uses it. feature/autolens/multi_plane_time_delays -- the time-delay equivalent of #480. tracer_util.time_delays_from raises on more than two planes, which #480 now makes reachable, and LensCalc.from_tracer binds the deflection callable to the plane while leaving potential_2d_from as the tracer's all-planes sum, so a plane-bound LensCalc computes a Fermat potential that mixes planes. refactor/autolens/one_construction_path_for_plane_bound_lensing -- three call sites each hand-roll their own plane-bound LensCalc and resolve the plane by different keys (profile name twice, redshift once). That duplication is why #480 could be wrong in one of them for four months. Dashboard regenerated in the same commit; intake dashboard --check is current.

Resolves the dashboard.md / dashboard.html conflict against cfeb11d ("mind: self-heal stale dashboard pages"). Both are generated pages, so the conflict was resolved by regenerating rather than by hand-picking hunks: intake --apply dashboard, then --check reports both current.

…; dashboard regen Close out the run-time dashboard task: record under complete/2026/09/, active prompt retired, active.md entry released, complete/index.md and the generated dashboard regenerated. The record notes the failed first Pages run (the token cannot create the site) and the human action that publishes it.

Summary
Mind state for the PyAutoLens#480 work (library PR: PyAutoLabs/PyAutoLens#712), plus the re-park that started the session and three follow-up prompts.
Four things, in the order they happened.
1. Re-parked
point_source_json_datasets_record_no_regime. A/start_devrun on this prompt hit its own step-1 gate: re-check two expiring facts before building. Both still hold, so nothing was built — no issue, no branch, no worktree. Recorded as a dated entry in its re-check log:updated_atbyte-identical tocreated_at(2026-04-28), no assignees, no closing PRs.weak/simpleis still regime-invariant —scripts/weak/simulator.py:122still callsvia_tracer_fromand reads noos.environ.It also records a standing risk the previous re-check missed: that simulator's own prose advertises
via_tracer_random_positions_from, the one change that would reverse the second fact, with no test guarding it.2. Filed and registered the #480 task.
active/point_solver_magnification_filter_ignores_plane_redshift.mdplus itsactive.mdentry. No new GitHub issue was opened — #480 already describes the bug, so/create_issuewas deliberately skipped and the entry points at the existing issue.3. Three follow-up prompts, all from cross-checking the #480 fix rather than from the fix itself:
draft/bug/autogalaxy/lenscalc_numpy_hessian_step_is_too_coarse.mdLensCalc's NumPy Richardson Hessian uses a hardcoded 0.01″ step. At the last plane of the #480 tracer it disagrees with both JAX autodiff and an independent ray-traced Jacobian by 122%, with the wrong sign on three of four points; the same comparison at the intermediate plane agrees to 1.7e-08.draft/feature/autolens/multi_plane_time_delays.mdtracer_util.time_delays_fromraises on >2 planes, which #480 now makes reachable, andLensCalc.from_tracerbinds the deflection callable to the plane while leavingpotential_2d_fromas the tracer's all-planes sum.draft/refactor/autolens/one_construction_path_for_plane_bound_lensing.mdLensCalcand resolve the plane by different keys (profile name twice, redshift once). That duplication is why #480 could be wrong in one of them for four months.4. Dashboard regenerated in the same commit as the intakes;
intake dashboard --checkreports current.Test Plan

The
