Hand-in Kit started with a small job: make a mixed folder of attachments easier to hand in. Version 2 makes that routine reusable and gives the pack a proper review step.

The naming preview works with manual ordering and per-file folders. Move a scan up, choose References for a file, or type a Hindi label, and its planned ZIP path changes before you download. Repeated names get a suffix rather than replacing another attachment. Search and type filters help review the list; hidden rows still stay in the pack.

The free recipe marketplace has seven starting setups. Each recipe stores naming, scan-size and budget settings with file-count requirements. You can save your own, edit it, or export/import a small JSON file. The README gallery shows a real example: Lab scans + notes, with two images, one document, an 8 MB budget and a CSV index.

Warm paper, mint desk and night ink have accent and spacing choices. There is also an exact-duplicate check with undo, original/prepared preview, exact ZIP budget, file checklist and JSON report. The message is editable and keeps your wording while other pack settings change. These are the twelve workspace additions explained in the README.

Two fixes mattered during checks: the earlier message field was read-only, and offline reloads with #marketplace missed the cached page. Both are fixed. Image headers are checked before decoding, so malformed or excessively large images can be kept unchanged rather than disrupting the pack.

On the public app, the two fictional scans went from a displayed 2.5 MB to 583 KB at the 300 KB target. The attached picture shows an original beside its JPEG copy. Small writing still needs a readability check, and PDFs are packaged unchanged.

The implementation has 21 passing automated tests, 13 syntax checks and a ZIP fixture checked by a separate Python reader. Browser checks covered recipe imports, Hindi filename collisions, duplicate removal/undo, completed downloads, mobile/tablet layouts and offline reloads. The README has now been rewritten around a short walkthrough, useful examples, five real screenshots, setup commands and honest limits. Its image files and local links were checked, and the eleven-file public build passed; the gallery is not added to the app bundle. The project banner and description were refreshed too.

The gallery shows the workspace, recipe marketplace, custom editor, Hindi filename pack and scan comparison. All scans shown are fictional demo files. Appearance and saved recipes can persist locally; attachments, names and messages in the workbench do not.

I requested the direction and features. Codex prepared the code, design, tests and writing and performed the recorded checks. This is substantially AI-assisted work. This edited post retains its original 2h 42m 13s attribution; no new hours are claimed by editing it. The README follow-up has its own devlog; that later record is separate from this original attribution.
