Summary

Renders the new PointSolver refinement figure (PyAutoLens#788, issue PyAutoLabs/PyAutoLens#787) and re-renders the point and cluster fit.pngs with the thinner model ✕.

• Real-solver diagnostic: point_solver.png for point_source_image_chi_squared and for each cluster plane (point_0, point_1). It shows steps 0, 1, 2 and final of the model's own solver. On these fine grids, steps 1, 2 and final look alike (sub-pixel triangles drawn as ▲), which the human accepted.
• Teaching figure: point_source_image_chi_squared/images/visualization/teaching/point_solver.png plus point_solver.gif, rendered by aplt.plot_point_solver on a coarse 11×11 @ 0.5″ grid (precision 0.01″). It is the approved variant_f_coarse look with arc-second ticks. The GIF has 4 frames (0, 1, 2, final) at 640×730, 1.25 s each with the final frame held 3.75 s, loops, and is about 0.13 MB.
  • Why this home: it uses the same dataset and true model as point_source_image_chi_squared, so it lives as a teaching/ sub-folder of that domain rather than a new pseudo-domain. The repo's rule is one folder per dataset type.
• GIF and the manifest: gallery/viz_manifest.yaml and GALLERY.md list PNGs only (the PyAutoEyes read contract), so the GIF is tracked beside its PNG still but is not a manifest entry. The builder is unchanged. render.yml already git add -As scripts/*/images, so release re-renders commit it. _viz_cli.mirror_to_scratch now also mirrors GIFs to the Eyes scratch.
• Config: config/visualize/plots.yaml sets fit_point_dataset: subplot_point_solver: true. It is off by default in the library.

Scripts Changed

• scripts/point_source_image_chi_squared/visualization.py: visualize(quick_update=False) so the visualizer writes point_solver.png (kept); adds the teaching still and GIF.
• scripts/cluster/visualization.py: computes the critical curves once per dataset, passes them to fit_point, and adds PlotterPoint.point_solver; keeps point_solver.png.
• _viz_cli.py: the scratch mirror copies *.gif too.
• config/visualize/plots.yaml, AGENTS.md, README.md, GALLERY.md, gallery/viz_manifest.yaml (68 → 72 PNGs).
• Re-rendered figures:
  • point_source_image_chi_squared: fit.png, point_solver.png, teaching/*
  • point_source_source_chi_squared: fit.png
  • cluster: point_{0,1}/{fit,point_solver}.png

Upstream PR

PyAutoLabs/PyAutoLens#788

Test Plan

• All three affected producers run against the PyAutoLens worktree branch:
  • point_source_image_chi_squared: 8 s
  • point_source_source_chi_squared: 1.4 s
  • cluster: 97 s per plane
• ruff check . and ruff format --check . are clean; gallery_build.py --check is current; pytest scripts/misc/test: 17 passed.
• CI lint is expected RED until PyAutoLens#788 merges. Its producers run against the library mains, where PlotterPoint.point_solver and aplt.plot_point_solver don't exist yet. Re-run after the library merge (library-first).
• Heart: YELLOW, pre-existing and acknowledged by the human: "manifest drift: workspace checkouts (manifest ↔ disk) — 1 mismatch(es) vs PyAutoMind/repos.yaml"; "release validation stale: source moved since rehearsal (PyAutoArray)".
