Summary

• Moves the Julia render stack from Julia 1.11.9 / Makie 0.21.9 / CairoMakie 0.12.9 to Julia 1.13.2 / Makie 0.24.16 / CairoMakie 0.15.16 (Project.toml compat, Manifest.toml regenerated by Pkg in a julia:1.13.2 container, setup-julia default 1.13). Since refactor: derive library versions from pins, install from uv.lock #12240 the displayed versions derive from the Manifest and the setup-julia default, so core/constants.py needs no change.
• Drops QRCoders from the environment. It is the dependency that pinned Makie at 0.21.9, and it still blocks every Makie release from 0.21.10 on. The generator and reviewer package lists now name it as not loadable.
• Updates prompts/library/makie.md: Figure(size = …) replaces the deprecated resolution keyword, the "API level" line names Makie 0.24, and a new "Makie 0.24 API Notes" section covers every break the before/after render found.

Why Makie was stuck on 0.21.9

The qrcode-basic implementation (#9398) added QRCoders, and the resolver moved Makie from 0.22.10 down to 0.21.9. The chain, confirmed with the resolver in a julia:1.13.2 container:

1. Every QRCoders release (1.0.0 to 1.4.5, and upstream master today) has compat ImageCore = "0.8, 0.9".
2. Makie 0.21.10 and later, all of 0.22 to 0.24 included, require ImageBase >= 0.1.7.
3. ImageBase 0.1.7 requires ImageCore 0.10, so no Makie after 0.21.9 can coexist with QRCoders.

QRCode.jl, the only other QR package in the General registry, has the same ImageCore 0.8 to 0.9 cap. The new Manifest avoids the conflict by not carrying a QR encoder at all. The prompt now says so, so a regeneration does not reach for one.

plots/qrcode-basic/implementations/julia/makie.jl stops running in the new environment and is left untouched. Its catalogue PNGs stay valid until it is regenerated; the generator will have to hand-roll the encoder or return NOT_FEASIBLE. An upstream compat PR to JuliaImages/QRCoders.jl (ImageCore 0.10) is a possible follow-up for the owner to decide.

Before/after renders

All 325 Makie implementations in both themes, no sampling. Each render is its own julia --project=<env> makie.jl process with ANYPLOT_THEME set, run from the implementation's directory as in impl-generate.yml. The renders ran in official julia:1.11 and julia:1.13 images with the action's apt packages. Before: Julia 1.11.9 with the committed Manifest. After: Julia 1.13.2 with exactly the Manifest in this PR. A pixel counts as changed when any channel moves by more than 16/255. "Near" means under 0.1 % of pixels changed.

Class	Specs	Renders
Identical	23	46
Near (< 0.1 % pixels)	251	502
Changed	45	90
Failed after the bump	5	10
Failed before, renders after	1	2

No render changed its pixel size.

Failures after the bump

All five are code written against old behaviour, not default drift:

• qrcode-basic: QRCoders is no longer installed (see above).
• area-mountain-panorama, line-parametric: GridLayoutBase 0.11.3 (upstream PR feat(highcharts): implement heatmap-correlation #68) makes rowgap!/colgap! honour offset indices. After a header at fig[0, …], rowgap!(fig.layout, 1, …) names a gap that does not exist and raises "invalid row gap". bode-basic and spc-xbar-r use the same pattern without crashing; they now resize a different gap.
• circos-basic: a custom recipe called with keyword arguments only; Makie 0.24 refuses it ("No plot arguments given").
• feynman-basic: the deprecated arrows! called inside a custom recipe hits a MethodError in the 0.24 compatibility shim.

Healed

• nyquist-basic was generated on Makie 0.22.10 and crashes on today's 0.21.9 runtime (BoundsError at save). It renders again on 0.24.

Silent breakage

• heatmap-polar exits 0 but saves a blank image: polar grid only, no title, data or colorbar. Any heatmap! on a PolarAxis does this in CairoMakie 0.15.15 and 0.15.16, for every input form, without an error; surface! and band! render. The canvas gate refuses it at review time (check_blank, AR-04: "Plot is 99% one color"), so a regeneration cannot merge blank. The prompt now forbids heatmap! on a PolarAxis and names the band! workaround.

The ten largest diffs

Spec	Max pixels changed	Cause
heatmap-polar	55.1 %	Blank render, see above
flamegraph-basic	45.8 %	Julia 1.13 changed hash(::String); frame colors are chosen by hash
biplot-pca	12.1 %	General eigen returns PC1 with the opposite sign (mirrored plot); deprecated arrows draw thinner
scatter-ashby-material	11.4 %	The family envelopes were missing on 0.21.9 and render on 0.24 (improvement)
bar-spine	11.0 %	Hatch pattern rework (Makie 0.22.2)
histogram-epidemic	10.6 %	Tighter automatic x-limits; bars stay on their dates
subplot-grid	8.9 %	Scientific tick labels lost the .0 padding (0.24.11), shifting the axes
swimmer-clinical-timeline	8.7 %	Julia 1.13 changed shuffle!; different patients
ma-differential-expression	8.6 %	Julia 1.13 changed randperm; different points
network-bipartite	5.8 %	Julia 1.13 changed randperm

Default drift is visible in the polar plots too: Makie 0.24.12 aligned the PolarAxis defaults with Axis, with a bold title, a thinner spine and lighter grid lines. Seeded rand and randn streams are unchanged between Julia 1.11 and 1.13.

Deprecated keywords

• resolution: 122 implementations pass Figure(resolution = …). All of them still render on 0.24 with a deprecation warning, so it is a warning, not a failure.
• arrows!: 16 implementations use the deprecated arrows!. All render except feynman-basic, with warnings about the renamed attributes.

Breaking changes handled in the prompt

From the Makie changelog 0.21.9 to 0.24.16 and the render results, each checked in the 1.13 container:

• Figure(size = …) instead of resolution (deprecated since 0.20).
• arrows2d! with shaftwidth/tipwidth/tiplength/tipcolor/shaftcolor (arrows! deprecated in 0.23).
• annotations! removed in 0.24, so the prompt names text! and the annotation! recipe instead.
• text! align must be a tuple.
• shading = false instead of NoShading.
• PseudologTicks/SymlogTicks for pseudolog10/Symlog10 (0.24.11).
• series! color cycling (0.24.16).
• Top-down layouts for rowgap!/colgap! (GridLayoutBase 0.11.3).
• No heatmap! on a PolarAxis.
• No hash/Dict order for colors.
• No QR encoder in the environment.

prompts/plot-generator.md and prompts/quality-criteria.md carry identical Julia "compute with" blocks, which a unit test compares with Project.toml. Both now move QRCoders from the installed list to "Not loadable". In the rubric this corrects which packages are installed and changes no criterion or deduction, so I dispatched no review-retest arm.

Regeneration candidates

• Must regenerate: qrcode-basic (QRCoders dropped), area-mountain-panorama, circos-basic, feynman-basic, line-parametric, heatmap-polar.
• Healed by this bump: nyquist-basic. Its stored images predate the 0.21.9 runtime and need no action.
• Optional: the 16 implementations on the deprecated arrows!, and bode-basic / spc-xbar-r, whose header gap moved.

First review (Gemini 3.8 Flash)

• Applied: plot-generator.md and quality-criteria.md still listed QRCoders as installed. The CI "Run Tests" job failed on that test before the fix.
• Skipped: the claim that arrows2d!, PseudologTicks and SymlogTicks don't exist. All three are defined in Makie 0.24.16, checked in the container.
• Skipped: adding PNGFiles to the action's no-Manifest fallback. That path predates this PR and never runs while Manifest.toml is committed.
• Skipped: fixing the failing implementations in this PR. plots/ is out of scope, and the pipeline regenerates them.

Dependencies and verification gaps

• refactor: derive library versions from pins, install from uv.lock #12240 (version sources): merged; this branch is rebased on it. core/constants.py and the makie.md header line take its form, and its "API level:" line now names Makie 0.24, which tests/unit/core/test_version_sources.py checks against the Manifest.
• setup-julia action: no local verification loop exists beyond the container run. Pkg.instantiate() on this Manifest and the action's smoke test both pass in julia:1.13.2. The first real check is the next Makie impl-generate run.

Plan

N/A

Test plan

• Before/after render of all 325 Makie implementations, both themes, in julia:1.11 / julia:1.13 containers
• Resolver run confirming the QRCoders → ImageCore → ImageBase → Makie chain
• Pkg.instantiate() and the action's smoke test on this Manifest in julia:1.13.2
• Prompt API notes checked against Makie 0.24.16 in the container
• ruff check, ruff format --check, mypy api core, pytest tests/unit tests/integration (12,277 passed)
• uv run python -m tools.changelog check --base origin/main
• Next Makie impl-generate run installs Julia 1.13 and renders
