Status
MacSurf has native file-input picking and browser-side upload plumbing, but the current QuickJS tree has no tracked implementation of the standard JavaScript Blob / File / FileReader surface. Repository search of the current workflow tree finds no corresponding implementation, while older loader code referenced only stub-era FileReader behavior.
This is a separate contract from <input type=file> multipart submission (#224): scripts need to inspect/read selected files and construct blob payloads even when no form submit occurs.
V1 scope
Blob construction from strings/ArrayBuffers/typed arrays with size, type, slice().File as Blob + name / lastModified for user-selected files.FileReader asynchronous readAsText and readAsArrayBuffer first; add data URL only if real-page evidence needs it.load, error, abort, loadend lifecycle and readyState/result/error semantics.- Integrate
<input type=file> selected-file objects with the JS surface without duplicating file bytes unnecessarily.
Object URLs (URL.createObjectURL) can be a follow-up if required.
Acceptance
A controlled page selects a local text file, sees a real File object, reads it as text and ArrayBuffer, receives exactly-once lifecycle events, and releases file/buffer resources on navigation. Also test a synthetic Blob without user file access. C89 and G3 hardware verification required.
