User's wasm binary (bin_bg.wasm) exceeds the 5 MiB per-file cap ("exceeds the maximum per-file size of 5242880 bytes"). Moderate bump chosen to fit large wasm while staying well under the Worker's ~128 MiB memory ceiling (body is buffered + decompressed in memory).
|
|
|
|
New coherent limit set:
|
|
- max_file: 5 -> 16 MiB
|
|
- max_uncompressed_total: 25 -> 48 MiB
|
|
- max_compressed (== MAX_UPLOAD_BYTES / body cap): 10 -> 24 MiB
|
|
- max_entries / max_path_len / max_depth: unchanged
|
|
|
|
Spots:
|
|
- core/upload.rs UploadLimits::default() (values + doc comment)
|
|
- routes/api.rs MAX_UPLOAD_BYTES const (+ comment); DefaultBodyLimit in routes/mod.rs follows it automatically
|
|
- static/index.html client-side MAX_UPLOAD_BYTES pre-check (line ~871)
|
|
|
|
Then: validate (all six), commit, push, deploy.

## Summary of Changes
|
|
Raised default upload limits to fit large wasm: max_file 5 to 16 MiB, max_uncompressed_total 25 to 48 MiB, max_compressed / MAX_UPLOAD_BYTES / axum body cap 10 to 24 MiB (max_entries/path_len/depth unchanged). Updated UploadLimits::default, routes::api::MAX_UPLOAD_BYTES, the frontend client-side pre-check + message, and design doc §2.2 numbers. Still well under the Worker ~128 MiB memory ceiling. Validation green: 196 unit + 20 doctests.
