## 2024-05-24 - Inline Validation for Required Inputs
**Learning:** Emptying a required input without clear validation feedback leaves screen readers and visual users confused, especially when aria-invalid is removed.
**Action:** Ensure inline validation messages are explicitly set and `aria-invalid` is properly toggled to `true` when a required field is cleared.
## 2024-07-15 - Dynamic Size formatting and Total Size Validation
**Learning:** Hardcoding human-readable sizes (like '5 GiB') in validation error messages is error-prone when the underlying constant changes. Moreover, failing to validate total upload size against backend limits (e.g., MAX_UPLOAD_BYTES) in batch file uploads frustrates users who wait for a large upload to finish only to get a server-side 413 Payload Too Large error.
**Action:** Always format backend byte limit constants dynamically (e.g., `formatBinaryBytes(MAX_UPLOAD_BYTES)`) on the client side to display accurate error messages. For multiple file inputs, ensure both the file count and the combined file size are validated against backend limits, giving immediate inline feedback via `setCustomValidity` and `aria-invalid`.

🟑 Raw patch artifacts committed to repo root

patch.diff, patch_test.diff, and patch_test2.diff are raw unified-diff files added at the repo root; the two test diffs are byte-identical duplicates. They are development leftovers, not source, and do not belong in the tree.

Prompt for agents 
Three raw diff files (patch.diff, patch_test.diff, patch_test2.diff) were accidentally committed to the repo root. patch_test.diff and patch_test2.diff are identical. Remove all three from the PR and from version control, and consider ignoring *.diff artifacts.

In `@saas_web.py` around lines 228 - 231, Handle empty-file submissions that fail
native required validation before the submit handler runs by applying the same
error message, styling, custom validity, and aria-invalid state from an
invalid-event path or shared pre-submit validation. Reuse the existing
empty-state behavior in updateFileSizePreview and updateBatchFilePreview so both
single-file and batch inputs display the inline error consistently.

πŸ“ Info: Required-message change is consistent across handlers

The four empty-state branches in updateFileSizePreview, the two numeric input handlers, and updateBatchFilePreview all now set the required message and aria-invalid. This matches the count of 4 in the new test and keeps the two if (this.value === '') occurrences intact.
