    • Binary file corruption on download: URL.revokeObjectURL() was called synchronously immediately after a.click(), before the browser had a chance to read the object URL. Downloads of binary files (Arrow, SQLite, Parquet, WASM, etc.) would produce 0-byte or truncated files. Revocation is now deferred by 30 seconds.
    • Binary write corruption for large files: The entire base64 payload was inlined as a string literal inside the inspectedWindow.eval() call, which can silently fail or corrupt data beyond undocumented size limits. Binary uploads are now staged into the inspected page's sessionStorage in 64 KB chunks, then reassembled and decoded inside OPFS atomically.
    • Binary files incorrectly classified as text: OPFS does not preserve MIME types — every file stored in OPFS has file.type === "". The previous __opfs_isTextFile check treated an empty type as text, causing binary files (Arrow, SQLite, WASM, Protobuf, .bin, etc.) to be read with file.text(), producing garbled UTF-8 in the editor. Classification now relies exclusively on file extension when the MIME type is absent.
    • btoa / Uint8Array.reduce call-stack overflow: Building the base64 binary string by reducing one character at a time over large Uint8Array buffers would exhaust the JavaScript call stack for images and binary previews beyond a few hundred KB. Replaced with an 8 KB chunked String.fromCharCode.apply loop.
    • escapeString missing null bytes and Unicode line separators: Null bytes (\x00) and Unicode line/paragraph separators (\u2028, \u2029) were not escaped, causing injected JavaScript to be syntactically invalid when file paths or text content contained these characters.
    • saveFile could corrupt binary/image files: The Cmd/Ctrl+S keyboard shortcut called saveFile even when viewing a binary file whose content was displayed as a [BINARY] or data:…;base64,… sentinel string. The sentinel text would be written back to OPFS, corrupting the file. A guard now blocks saves when the displayed content is a read-only sentinel.
    • stageBinaryData sessionStorage leak on error: If staging a chunk failed (e.g. sessionStorage quota exceeded), already-stored chunks were never removed, leaking __opfs_bin_* keys in the inspected page's sessionStorage indefinitely. Staged chunks are now cleaned up on any staging error.
    • Undefined base64 crashing upload: FileReader produces a data URL; content.split(',')[1] returns undefined on a malformed result. This was passed into stageBinaryData which then crashed with a misleading error. An explicit guard now throws a descriptive error.
    • Conflict resolution applied wrong target directory to pending uploads: After resolving a file conflict, remaining queued uploads were all sent to the first file's target directory, ignoring each file's own intended path. Each pending upload is now dispatched with its own original targetPath
