 - **Tolerant `Color ==`:** `ColorExtension.swift` overrides `Color ==` with a 0.1-per-channel tolerance that shadows SwiftUI’s and drives `SettingsStore` equality, so small colour edits do not mark a configuration dirty. It is not transitive — never put `Color` or `SettingsStore` in a `Set`, key a dictionary on them, or dedupe an array. Full reasoning in **GUARDRAILS.md → Signs**.

 15. **Workflow Extension does not migrate settings.** `RolesManager` JSON-decodes `SettingsStore` with no `SettingsVersioningManager`. Open the main app after a schema bump.
 16. **FCPXML `UTType` force-unwrap** — `UTType("com.apple.finalcutpro.xml")!` traps on Extract first layout when Final Cut Pro is absent (App Preview / review Macs). Use `importedAs` fallback and Info.plist imported types. Do not copy the old Marker Data force-unwrap.
 17. **File menu Close last:** custom File items replace `.newItem`. Emptying `.newItem` makes system Close the first File item; do not duplicate Close.
-18. **`Task { try await MainActor.run { … } }` inside a `throws` method swallows the error.** The task result is discarded, so the method always returns normally and the caller’s `catch` is dead. `DatabaseManager` is already `@MainActor` — call directly and let the error propagate. `duplicateProfile` was fixed this way; `setActiveProfile` and `loadProfilesFromDisk` still use the wrapper but throw nothing, so they are harmless. Do not reintroduce the pattern for anything that validates.

Do not reintroduce `try` on those wrappers, and do not use the pattern for anything that validates.
 19. **Record an extract failure once.** `extractAndUpdateProgress` must rethrow the `MarkersExtractor` error, not append to `failedTasks` — appending there and then tripping the `exportResultisNil` guard produced two entries for one file, the second reading “Failed to get export result”, and duplicate `ExtractionFailure.id` (the URL) in `FailedExtractionsView`. The task group `catch` is the single recording point.
 20. **`NSAlert` does not pick up the Icon Composer icon**, and its `alertStyle` defaults to `.warning`. Pagemaker’s WebView JavaScript panels are the app’s only `NSAlert`s — route them through `PagemakerUIDelegate.makeAlert(message:)` (sets `MarkerDataAppIcon.alertImage`, `.informational`, message as `messageText`). Never re-add generic “Alert” / “Confirm” / “Prompt” titles; SwiftUI dialogs elsewhere have no such title. Keep `confirm` returning `.alertFirstButtonReturn` so Cancel reaches JavaScript as `false`.
 21. **`Color ==` is tolerant, app-wide, and not transitive.** `ColorExtension.swift` defines `static func == (Color, Color)` delegating to `isEqual(to:tolerance: 0.1)`; Swift prefers the same-module declaration, so this shadows SwiftUI's exact `==` for **every** `Color` comparison compiled into the main app — including synthesized `Equatable` on `SettingsStore` (verified). Consequences: a colour tweak under ~25/255 in all three channels leaves `SettingsContainer.checkForUnsavedChanges()` false, so the Configurations “Changed” badge and ⌘S / ⌘Z stay disabled even though `preferences.json` was already updated; and `0.0 == 0.1`, `0.1 == 0.2`, `0.0 != 0.2` breaks `Equatable` transitivity, so never put `Color` (or `SettingsStore`) in a `Set`, use it as a dictionary key, or dedupe an array of them. The tolerance exists because `Color.hex` **truncates** (`Int(components.red * 255.0)`): 179 of 256 sampled colours drift one step through encode/decode, which under exact equality would mark the store permanently dirty. Fix properly by rounding in `hex` and comparing `lhs.hex == rhs.hex` — measured zero round-trip failures — not by lowering the tolerance alone. Note `hex` also feeds `imageLabelFontColor` / `imageLabelFontStrokeColor`, so the drift reaches rendered labels.
 22. **Pagemaker’s `confirm` panel is unreachable in-app — do not “verify” it by clicking.** The only `confirm(` in bundled `Resources/Pagemaker.html` is gated behind `isMacOSSafari()`, and WKWebView’s default user agent carries no `Safari` token, so the branch never runs inside Marker Data. `webView(_:runJavaScriptConfirmPanelWithMessage:…)` must still return `.alertFirstButtonReturn` correctly (Sign 20), but that contract cannot be exercised from the UI — reason about it, don’t test-and-conclude. Two things would make it live: setting `applicationNameForUserAgent` to include `Safari`, or an upstream Pagemaker change, since `update_pagemaker.yml` refreshes that HTML outside this repo’s review.
 23. **`.appDialogIcon()` propagates through the environment.** It wraps SwiftUI `.dialogIcon(_:)`, so one trailing call covers every `.alert` / `.confirmationDialog` earlier in the same modifier chain. `ConfigurationSettingsView` has four dialogs and **one** call — that is correct, not a missing icon; `DatabaseSettingsView`’s three calls are redundant but harmless. Only a dialog-bearing chain with **no** call anywhere is broken. Keep adding one per dialog in new code (safe habit), but do not “fix” an existing single trailing call.
+24. **Unused throwing unstructured `Task` (Xcode 27 / `#NoUseUnstructuredThrowingTask`).** `Task { try await … }` without storing the task or catching inside silently drops errors. Handle with `do/catch` (or drop a spurious `throws` / `try`) so the task is non-throwing; on `@MainActor` types, call directly. Do not silence with `_ = Task`.
