Implements the `AssumeRoleWithWebIdentity` and `GetCallerIdentity` STS actions, letting callers exchange an external OIDC token for temporary credentials scoped to an IAM role. Token handling covers JWT claim parsing, issuer/audience resolution (including `azp` override semantics), JWKS fetching and caching with `singleflight`-deduplicated refresh, and rate-limited forced refresh on unrecognized `kid` values. OIDC provider thumbprint fetching now performs a real TLS handshake verified against the system trust store and the provider hostname (previously `InsecureSkipVerify`), since the observed certificate is persisted as a long-lived trust anchor rather than used once and discarded; all discovery-document and JWKS fetches go through an SSRF-safe HTTP client with bounded redirects and response size.
Adds policy `Condition` block evaluation, supporting `String`, `Numeric`, `Date`, `Bool`, `BinaryEquals`, and `IpAddress` operators along with their `IfExists`/`Not` variants and `ForAllValues`/`ForAnyValues` set qualifiers, plus policy variable substitution (e.g. `${aws:username}`) in supported operators. Adds identity-based inline policy evaluation and a new IAM authorization middleware that authorizes each request against action, resource, and condition context together, applying the session-policy-intersects-role-policy semantics for assumed-role sessions.
Adds a new debug logger `--log-level` flag (`silent`/`debug`/`unsafe`), along with a tree-based XML masker that redacts secrets and tokens at the property level in logged request/response bodies instead of skipping the whole body. The old `--debug/VGW_DEBUG` flag is kept as a deprecated alias for `--log-level=debug`, printing a console warning that points users at `--log-level` for finer-grained control.
Fixes a Vault storage bug where CAS (check-and-set) writes always read the current document version as 0 because `kvVersion` asserted metadata as `float64` while the Vault client actually returns `json.Number`, causing every write past the first to be rejected as a concurrent modification. Also adds a constant-time `SecureCompare` for signature/token comparisons in sigv4 auth.
Adds an integration test suite (`iam_access_control.go`) covering IAM access control across user, role, and session identities.
