Base merge (orphan sweep, 2026-10-21)

Merged feat-cmux-next at 5e76238. BackdropSelectionSetting.parse keeps the removed-id fallback ahead of the base's new shuffle parse. Two tests the base added since name a removed work and now use Forest Interior by Moonlight: DragGlassTests (it pinned .goyaSaturn, which no longer exists) and sliderRows.test.tsx. The CmuxNextDesign catalog is the base's minus the 28 titles; settings exports are the base's, for the autofix. generate_backdrop_art.py --check reports only key order in the catalog and omissions files (same content as it would write), and export-backdrop-art.py --check is current. 12 bundled works, 146 in the catalog and in Shuffle Daily.

No capture: the change removes works from the background catalog; no layout, control or styling changes (the picker lists fewer tiles).

risk: normal

Summary

Removes 28 backdrop works, leaving 146.

• The backdrop picker and daily rotation now use a smaller art catalog.
• Saved settings with removed artwork now use the default background.
• The settings art gallery now shows works from the revised collection.

No builds or runtime tests were run.

[teamleaderleo]

Correctness review (subagent, read-only) of head c159ee6, base feat-cmux-next. Owner: teamleaderleo (agent lane of coordinator leoli-63).

Verdict: no blocking findings.

• No code still references .goyaSaturn or GOYA_SATURN. The id remains only as a string in removedIDs and the new tests. The JSON files parse, and there are no gallery baselines for curated-art.
• removedIDs is public through its public nonisolated extension and visible to CmuxNextSettings and the tests. The test argument types and the Equatable checks are fine.
• dailyRotation == BackdropArt.allCases: both lists have the same 173 entries in the same order. export-backdrop-art.py --check passes.
• 15 works are bundled, inside 12...24 and all dark. bocklinIsleOfTheDead, the new art in WebviewPaneOneEdgeTests, is bundled.
• Fallback: both keys resolve to defaultSelection with no diagnostic, and a workspace pin falls back to .inherit. The Rust effective_value falls back to the default once the schema is regenerated.
• Expected until the PR autofix commit: the settings exports, the sources stamp and the defaults snapshot still list goya-saturn. This is the defaults-snapshot red.

Findings and resolution:

1. Low: shuffleDailyNeverShowsGoyasSaturn still had its old name and comment. Renamed to shuffleDailyShowsAWorkEveryDay in 3603424.
2. Low: the rotation comment said "only when someone lists it", which conflicts with the whole-catalog test. Reworded in 3603424.
3. Info: removedIDs isn't exported to backdrop-art.json. No change; GPUI falls back through the Rust settings code.

Correctness review of the 28-work removal (subagent, read-only), head 032d260, base feat-cmux-next. Owner: teamleaderleo (agent lane of coordinator leoli-63).

Finding (medium, blocking): a removed work someone already downloaded came back as one of their images.

• 21 of the removed works download on first pick, and the downloaded .avif stays in the Backgrounds folder.
• BackdropUserImages.isDownloadedArt only recognized ids that BackdropArt still knows, so after this PR those files would be listed under Your images.
• Fixed in aeac345: isDownloadedArt now also matches BackdropArt.removedIDs, plus retired ids via BackdropArt(id:). BackdropUserImagesTests adds a goya-witches-sabbath.avif download and checks that it is neither listed nor contained.

Verified, no issue:

• No references to the removed works remain outside the negative tests.
• Placement thresholds 146/144/146 match framing_sheet.py (keeps plus fills, which is keepsSubject).
• ArtAccent ratio: 77 hues out of 146 works passes.
• Bundled set: 12 works, all dark.
• File checks: every bundled work has its .avif, all 146 have a thumbnail, and there are no orphans.
• dailyRotation equals allCases.
• Localizable.xcstrings and the omissions file are pure deletions: 28 keys, valid JSON.
• The gallery fixtures match their imports.
• export-backdrop-art.py --check passes.

CI on 032d260 (not caused by this PR):

• The cmux-next checks reds (type scale, concurrency, dialog keys, browser icons, script tests, job structure) are the same set that is red on feat-cmux-next.
• The webview shard failures are agent-pane, composer, chat-find and popup tests unrelated to backdrops.
• The merge freeze and autofix jobs died on "API rate limit exceeded for installation". The new push re-runs them.

Generated-files check fails

ci-target-graph.json now lists CmuxNextHostedChief, which Package.swift does not declare. It also adds CmuxNextFeed as a direct dependency of CmuxNextAppTests, which the package does not declare either. The generator reads these entries from Package.swift, so its output cannot match this file. CI rejects that mismatch. Regenerate the graph from this PR's checkout.

Review (claude-reviewer-22336): SHIP at 509a9bf

Independent read-only review of the merged head against the merged base 5e76238. No builds or tests were run.

Checked:

• Removed set: BackdropArt.removedIDs (28 ids) equals base manifest minus head manifest exactly. 174 → 146 works, no additions. 12 bundled; the three new ones (velde-small-ship-storm, friedrich-forest-moonlight, el-greco-view-of-toledo) have full images and thumbs.
• Fallbacks: new key (parse) and legacy key (appearance.backdropArt) both return the default with no diagnostic; workspace pin goes through BackdropSelection(id:) → .inherit; Settings writes of a removed id are refused via BackdropSelectionSetting.accepts.
• Downloads: BackdropUserImages.isDownloadedArt excludes removed-id .avif files from "Your images".
• Rotation: dailyRotation is exactly allCases in the same order (146, no dups), so shuffle/daily cannot land on a removed case.
• Dangling references: no remaining BackdropArt.<removedCase> references in Packages, webviews, scripts, cmux-tui, or plans. retiredIDs targets are not removed. The only removed-id strings outside the expected files are in tests that assert the fallback, plus docs/mdm/* and schemas/settings/settings-schema.json, which the autofix bot regenerates (as intended).
• Generated files: export-backdrop-art.py --check is current. generate_backdrop_art.py --check reports Localizable.xcstrings and localization-allowed-omissions.json stale; I compared parsed JSON in memory, and the content is identical (key order only). Base has the same pattern (work keys sit in their original positions, not at the end where the generator puts them), so this is pre-existing, not introduced here.
• Base drift: merge-tree of the head onto current origin/feat-cmux-next tip is clean. Two later base commits touched settings.gallery.ts only, with no overlap.

Non-blocking notes:

• isDownloadedArt now uses BackdropArt(id:), so retired-id downloads (earlier set) are also hidden from "Your images". That is arguably right, but it is a behavior change beyond the 28 removals.
• A workspace pin on a removed id resolves to .inherit (follows the app background), not the off default. This matches the existing unknown-id behavior and the test asserts it, but it is a judgment call against "fall back to the default background".
• Settings schema and docs/mdm still list removed ids until the autofix bot regenerates them; the schema/export check will be red until then.

Review (claude-reviewer-22336b): SHIP at 083df21

Checked against origin/feat-cmux-next (merge-base 3f206f4):

• Net diff is the backdrop removal, its generated outputs and test updates. The Swift and webview logic changes are the removal fallbacks (BackdropArt.removedIDs, BackdropUserImages, BackdropArtSetting, BackdropSelectionSetting) and the settings gallery/test ids.
• No reference to the 28 removed ids or enum cases (goyaSaturn, bocklinIsleOfTheDead, ...) outside removedIDs and the fallback tests (WorkspaceBackgroundTests:115, BackdropArtCatalogTests:57, BackdropUserImagesTests:52,60). Nothing in docs, schemas, plans, art manifest, scripts or gallery.
• Enum 174 → 146 cases, matching the 146 thumbnails. Localizable.xcstrings drops only the 28 backdrop.<id>.title keys, with no value changes to other keys. localization-allowed-omissions.json and framing.json only lose lines.
• export-backdrop-art.py --check, defaults_guard.py check-stamp and check-fresh all pass. The working tree is clean.
• defaults/cmux-next.json and the MDM exports also pick up base drift that was already in source but missing from the stale base exports: workspaces.newPlacement top→afterCurrent (source already afterCurrent on base), home.server, notifications.attention.flash*, notifications.showPreviews, key.markdownReload, and similar. Not new defaults invented by this PR.

Non-blocking notes:

• Velde, Friedrich and El Greco now ship bundled, per the 032d260 commit message (keeps the starter set at 12 dark works). Intentional.
• 083df21 was applied from the autofix artifact by hand. The content passes the generator checks, so I did not re-download the artifact.

Review (claude-reviewer-22336c): SHIP at b67255c

Checked the net diff against origin/feat-cmux-next and the generated outputs since 5c92af7.

• Removed set: BackdropArt+Library.swift removedIDs has 28 ids. The base enum has 28 cases gone, and they match exactly.
• No stray references: a sweep of every non-binary file at the head for the 28 raw ids and their camelCase cases hits only removedIDs, the fallback tests (BackdropArtCatalogTests, WorkspaceBackgroundTests, BackdropUserImagesTests), and nothing else. No .xcstrings hits.
• Exports: docs/mdm/com.manaflow.cmux.json, docs/mdm/com.manaflow.cmux.plist and schemas/settings/settings-schema.json parse (plist via plutil -lint). Since 5c92af7 they have zero added lines. A structural comparison against base shows only the 28 ids removed, with surviving options unchanged and in order, and no trailing-comma or adjacent-option damage. managed-preferences.md and settings-schema.sources.sha256 change only the two stamp lines.
• python3 -I scripts/ci/defaults_guard.py check-stamp --base 5c92af7a3b81f22fc07d87d2e9fb6fcc029d2689 passes. schemas/defaults/cmux-next.json is unchanged from base.
• python3 -I scripts/cmux-next/export-backdrop-art.py --check passes. The full-size Resources copies of el-greco, friedrich-forest-moonlight, velde-small-ship-storm and martin-pandemonium are generator output, not hand edits.

Non-blocking: defaults_guard.py check-fresh exits 1 with key.closeWorkspace and setting.workspaces.newPlacement drift. This PR doesn't touch either key, and both lines are identical on origin/feat-cmux-next, so it is base drift.

No blocking findings.
