- Replace `interface{}` with `any` type alias across all packages
- Use built-in `min()`/`max()` for parameter clamping
- Use `slices.SortFunc`, `slices.Min`, `slices.Max` for cleaner code
- Use `strings.Cut()` for simpler string parsing in auth middleware
- Use `errors.Is()` for proper error comparison in handlers
- Update dependencies: golang.org/x/image 0.37.0 -> 0.38.0
- Add Wire code generation guidelines to ARCHITECTURE.md
- Disable Go cache in CI build workflow
Map INVALID_CREDENTIALS to http.StatusBadRequest (400) instead of
http.StatusUnauthorized (401) to better align with client error semantics.
Update ErrorWithStringCode to return the HTTP status code in the 'code'
field and set 'data' to nil, removing the legacy compatibility workaround
that set 'code' to 0.
BREAKING CHANGE: Response structure for ErrorWithStringCode changed (Code
field now returns status code, Data is nil) and INVALID_CREDENTIALS status
changed from 401 to 400.
- Add Google Wire for compile-time dependency injection
- Replace concrete service types with interfaces across handlers
- Remove global state (DB, cache) in favor of constructor injection
- Split monolithic files into focused modules:
- config: separate files for each config domain
- dto: converters split by domain (user, post, message, group)
- cache: separate metrics.go and redis_cache.go
- Introduce unified apperrors package with string-based error codes
- Add transaction support with context-aware repository methods
- Upgrade golang.org/x/crypto from 0.17.0 to 0.26.0
Align group and conversation handlers/services with path-based endpoints, and unify response/service error handling for related modules.
