precedence bug: localStorage trumps project defaults -- projects/[id]/page.tsx always sends bin_config: project.default_bin_config || getDefaultBinDefaults(). Since bin_config is always truthy, the backend fallback req.bin_config or project.default_bin_config in routes.py never reaches project.default_bin_config. Global localStorage defaults silently override server-stored project defaults.

should fix

silent BinDefaults to BinConfig upcast -- _build_bin_from_tools does BinConfig.model_validate(default_config.model_dump()) where default_config is BinDefaults (lacks text_labels). Works because text_labels defaults to [], but if BinConfig gains a field with a non-trivial default this breaks silently. Consider explicit construction.

binDefaultsFromConfig manually enumerates fields -- fragile; adding a field to BinDefaults requires updating this function. Destructure to strip text_labels instead: const { text_labels, ...defaults } = buildBinConfig(config).

defaultsStatus message never clears -- "Defaults saved" / "Defaults reset" persists until navigation. Add a timeout.

no test for project update round-trip -- PUT /api/bin-projects/{id} with default_bin_config is untested.

no guard for localStorage unavailability -- saveDefaultBinConfig and resetDefaultBinConfig call localStorage.setItem with no SSR/private-browsing guard.

nits

• dev.ps1 (167 lines) is out of scope for a "default bin settings" PR -- should be a separate PR

good contribution overall -- the BinDefaults/BinConfig type split is clean, test coverage is solid, and the feature addresses the request in #49. The precedence bug is the main thing to sort out.

all previous feedback addressed. tests pass, clean security audit. minor suggestions (no-op exclude in routes.py, bed_size validator) can be follow-ups.

thanks again @noobydp!
