Affected repositories: HowToGalaxy, autogalaxy_workspace_test, autolens_assistant, autogalaxy_assistant, autocti_assistant.
Branch: feature/workspace-prior-copies; worktree root: /home/jammy/Code/PyAutoLabs/.worktrees/workspace-prior-copies. For existing contributor PRs, retain their head branches instead.
All canonical checkouts are on main. Existing untracked dataset.fits in autolens_workspace and the schematic PNG in autolens_assistant are excluded. No other session holds registered repo claims; this session coordinates its own overlapping tasks sequentially on isolated branches. The unrelated PyAutoFit detached worktree is untouched.

Key files, changes and validation: Apply the bounded PyAutoGalaxy#618 corrections to each listed config/priors tree, including autogalaxy_workspace_test/scripts/misc/aggregator/config/priors: ersic typo, dead NFWTruncatedMCRScatterLudlowSph key path, orphan linear chameleon/eff files, PointSourceChi, SersicCoreSph.mass_to_light_ratio, linear-operated Gaussian.intensity and obsolete Voronoi README mention. Inspect each full file and current packaged defaults before targeted edits; preserve unrelated overrides. Replace the obsolete fits.flip_for_ds9 with the supported fits setting if present and replace readerless plots_search sampler sections with supported nest/mcmc/mle sections preserving meaningful switches. Keep Euclid untouched. Validate YAML and changed prior keys, instantiate representative models and run applicable smoke checks. No new library behavior.

Acceptance is the original prompt's witness, evaluated against current source; stale reported defects must be identified rather than recreated. Preserve original task scope and separate task/PR identity. No separate bundle backlog.

  Witness: A diff of every listed config/priors copy (HowToGalaxy, both autogalaxy_workspace_test copies, the three assistants) against the packaged PyAutoGalaxy config/priors shows none of the #618 dead rows (the ersic typo, NFWTruncatedMCRScatterLudlowSph, the orphan chameleon.yaml/eff.yaml, PointSourceChi, SersicCoreSph.mass_to_light_ratio, linear-operated Gaussian.intensity, Voronoi in mesh/README.md), each repo's general.yaml/plots_search.yaml carries the replacements for the readerless keys, and the euclid pipeline copy is untouched.
  Review-minutes: 3
  Unattended: ready

Remaining config/priors copies still carry the drift rows fixed by PyAutoGalaxy#618. PR #619 fixed the packaged autogalaxy/config/priors/ and the workspace PRs on #618 re-synced autolens_workspace, autogalaxy_workspace, HowToLens and autolens_workspace_test. The same dead rows (ersic typo in light/operated/sersic.yaml, NFWTruncatedMCRScatterLudlowSph under nfw_truncated_mcr.yaml, orphan light/linear/chameleon.yaml + eff.yaml, PointSourceChi, SersicCoreSph.mass_to_light_ratio, linear-operated Gaussian.intensity, Voronoi in mesh/README.md) still exist verbatim in: HowToGalaxy/config/priors, autogalaxy_workspace_test/config/priors and its second copy autogalaxy_workspace_test/scripts/misc/aggregator/config/priors, autolens_assistant/config/priors, autogalaxy_assistant/config/priors, autocti_assistant/config/priors. Apply the same edits (as edits, not blind copies; check each repo's general.yaml for the readerless fits.flip_for_ds9 and visualize/plots_search.yaml for the unread per-search dynesty:/emcee:/nautilus:/zeus: form, replace with PyAutoFit's nest/mcmc/mle file). euclid_strong_lens_modeling_pipeline keeps its copy by design (euclid#43). Also note autogalaxy_workspace/config/priors/ellipse/ellipse_multipole.yaml has no EllipseMultipoleScaled block (falls through to the packaged one; informational). Consider a shared parity check that diffs every workspace config/priors against the packaged PyAutoGalaxy copy.
