Consolidate subscription usage policy enforcement, privacy-safe persistence, and gateway security hardening into one reviewable change.
Includes bounded HTTP and execution envelopes, header and protocol guards, DNS and relay validation, authentication and secret projection hardening, secure backup/install paths, and regression coverage.
Preserve exact request payloads and model client surface and API operation explicitly.
Add Anthropic compatibility profiles, bounded stream commitment, and scoped OAuth retry behavior across provider transports.
Introduce aether-data-schema and driver-specific schema generation for Postgres, MySQL, and SQLite.
Split data backends, lifecycle, repositories, and gateway runtime integration across database drivers.
Verified with cargo fmt --all --check, cargo clippy --workspace --all-targets -- -D warnings, and cargo test --workspace.
Extract request_auth_channel as a distinct routing dimension to distinguish
between api_key and bearer_like authentication methods. This improves routing
clarity by decoupling authentication mechanism from route classification.
