// The frontend's domain errors (CONTEXT.md "Image decode error",// "Thumbnail encode error", plus the editor-internal states they name).// Every class follows the engine/store convention: a `Schema.TaggedErrorClass`// with a `message` and an optional `cause`, so failures can cross the// foldkit message boundary as validated values and be caught by tag.//// Posture (docs/adr/0010): these are recoverable failures — they sit on the// Effect error channel of commands. Defects (programmer errors) are tagged// throws instead, e.g. `MountElementError`.
/** * A source image could not be loaded — reading a picked file's bytes, * decoding it into an `ImageBitmap`, or decoding a saved Edit's source * bytes. One concept whether the browser API failed or the file is corrupt: * the user-visible failure is the same — the image cannot be opened. */export class ImageDecodeError extends Schema.TaggedErrorClass<ImageDecodeError>()( 'ImageDecodeError', { message: Schema.String, cause: Schema.optional(Schema.Unknown), },) {}
/** * A thumbnail (the small JPEG of the graded result or the picked photo that * seeds an Edit) could not be encoded — no 2d context, or a * `convertToBlob` failure. Distinct from the engine's `EncodeError` (the * export encoder's contract): thumbnails are downscaled by canvas 2D, * exports by the worker encoder. */export class ThumbnailEncodeError extends Schema.TaggedErrorClass<ThumbnailEncodeError>()( 'ThumbnailEncodeError', { message: Schema.String, cause: Schema.optional(Schema.Unknown), },) {}
/** * A mount's element contract was violated: the stream needs an `HTMLElement` * (typed wheel/pointer APIs) and foldkit mounted it on a plain `Element`. * The app's own markup always satisfies this, so it is a defect — thrown, * not Effect-failed. */export class MountElementError extends Schema.TaggedErrorClass<MountElementError>()( 'MountElementError', { message: Schema.String, cause: Schema.optional(Schema.Unknown), },) {}
/** * The render command ran before the canvas mount registered itself (or the * mount never ran).

/** * The attached Edit (`/edit/:id`) does not exist — a stale URL or a deleted * tile.

/** * A field lookup on a known layer type missed — `fieldBounds` was asked for * a field the layer's UI metadata does not define.
