**Vulnerability:** Path traversal in `media_shrinker.py` via unresolved `..` segments or symlink escapes before deriving conversion output paths.
**Learning:** `Path.relative_to()` is only a lexical containment check unless both the source and root have first been resolved into canonical absolute paths. Relative paths and symlinks can otherwise bypass root-boundary assumptions.
**Prevention:** Resolve both source and root once, reject sources outside the resolved root with a sanitized `MediaShrinkerError`, and derive `rel_source` from the resolved paths before planning outputs.

As per coding guidelines, saas_web.py must source runtime API keys, database credentials, endpoints, and other secrets from the credential registry/KV rather than directly from environment variables; migrate API-key authentication away from CODEC_CARVER_API_KEYS as a runtime environment-variable source.

minimal, and validate.

In `@saas_web.py` at line 117, Update get_configured_api_keys in saas_web.py to
retrieve runtime API keys from the credential registry/KV instead of os.environ
and CODEC_CARVER_API_KEYS, while preserving the existing HMAC comparison
behavior. Update the related authentication tests to configure and read keys
through the registry/KV.

In `@tests/test_saas_web.py` around lines 1225 - 1248, Update
test_auth_unicode_encode_error to use unittest.mock.patch.dict when setting
CODEC_CARVER_API_KEYS, so the test restores any pre-existing environment value
and cleans up even if setup or execution raises; remove the manual deletion in
the finally block.
