* sts: recognize issuer-scoped parent user ids
ComputeParentUser output has a fixed shape (base64url SHA-256); let
callers distinguish it from bare subject strings.
* s3tables: keep legacy owner re-anchoring off local and scoped account ids
Re-anchoring a stored bare subject under the single trusted issuer must
only apply to strings that could actually be a legacy OIDC subject. A
stored owner naming the reserved or a configured local account, or an
already issuer-scoped id, can otherwise be claimed by any caller whose
token asserts that string as sub.
* s3tables: re-anchor legacy policy principals in map and array forms
A stored bare subject can appear as {"AWS": sub} or inside a principal
list, not only as a top-level string; re-anchoring only the string form
left legacy Deny statements unable to match the caller.
* s3tables: keep built-in legacy exclusions independent of the account checker
A missing local-account predicate must not disable re-anchoring entirely:
the reserved accounts, ARN-shaped values, and scoped-id shapes are never
OIDC subjects regardless, while legacy Deny statements for plain subjects
still need to resolve so a denied caller cannot fall through to an
identity grant.
* s3tables: exercise legacy Deny against an owner grant
The previous case denied the caller regardless of whether the statement
principal matched; make the caller the owner so a missed match shows.
Cover the array Deny form alongside the AWS map.
* s3tables: let an explicit policy Deny veto fallback and owner allows
Table operations evaluated the table or namespace policy and the bucket
policy as an OR, so an explicit Deny in one policy was overridden by an
Allow in the other. Owner and identity grants also short-circuited
before the resource policy was read. Deny statements are now evaluated
first at both levels, matching AWS explicit-deny semantics.

* s3tables: scope OIDC-derived account IDs to the token issuer
Table ownership keyed off the bare sub claim, so two identity providers
issuing the same sub collided on one account - a caller could act on
tables owned by a different provider's user. OIDC bearer tokens now
carry the same issuer-namespaced (sub, iss) hash STS sessions already
expose as aws:userid, and getAccountID prefers it over the raw claims.

* s3tables: keep legacy owners working and scrub client-subject claims
- OIDC bearer tokens without a subject are rejected, and a token-supplied
aws:userid claim is always overwritten with the verified (sub, iss)
hash, so a forged claim can no longer stand in for the principal.
- Owners written before issuer scoping hold a bare subject; permission
checks now re-anchor that subject under the caller's issuer, so the
same (sub, iss) pair keeps its ownership while scoped owners remain
issuer-isolated. The token issuer is asserted into claims alongside
sub and carried through PolicyContext.
* s3tables: anchor legacy subjects to the configured issuer set
* s3: enumerate trusted issuers from registered providers too
* s3: fail closed when the OIDC provider store cannot be listed
trustedOIDCIssuers kept the registered issuers when ListOIDCProviders
failed, presenting a partial set as complete. A deployment trusting one
registered issuer A plus a stored issuer B would, on a listing error,
report only A — the single-issuer shape under which a legacy bare
subject re-anchors — letting a caller from A claim a stored subject
that belongs to B and gain owner access.
With no provider store the registered providers are provably complete,
so keep returning them; with a store, a failed listing means the real
set is unknown, so return none.

* S3: Implement IAM defaults and STS signing key fallback logic
* S3: Refactor startup order to init SSE-S3 key manager before IAM
* S3: Derive STS signing key from KEK using HKDF for security isolation
* S3: Document STS signing key fallback in security.toml
* fix(s3api): refine anonymous access logic and secure-by-default behavior
- Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions.
- Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration.
- Update `NewIdentityAccessManagement` signature to accept `filerClient`.
- In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior.
- Use specific `LookupAnonymous` method instead of generic map lookup.
- Update tests to accommodate signature changes and verify improved anonymous handling.
* feat(s3api): make IAM configuration optional
- Start S3 API server without a configuration file if `EnableIam` option is set.
- Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode).
- Handle empty configuration path gracefully in `loadIAMManagerFromConfig`.
- Add integration test `iam_optional_test.go` to verify empty config behavior.
* fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore
* fix(iamapi): properly initialize FilerClient instead of passing nil
* fix(iamapi): properly initialize filer client for IAM management
- Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses.
- Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality.
* clean: remove dead code in s3api_server.go
* refactor(s3api): improve IAM initialization, safety and anonymous access security
* fix(s3api): ensure IAM config loads from filer after client init
* fix(s3): resolve test failures in integration, CORS, and tagging tests
- Fix CORS tests by providing explicit anonymous permissions config
- Fix S3 integration tests by setting admin credentials in init
- Align tagging test credentials in CI with IAM defaults
- Added goroutine to retry IAM config load in iamapi server
* fix(s3): allow anonymous access to health targets and S3 Tables when identities are present
* fix(ci): use /healthz for Caddy health check in awscli tests
* iam, s3api: expose DefaultAllow from IAM and Policy Engine
This allows checking the global "Open by Default" configuration from
other components like S3 Tables.
* s3api/s3tables: support DefaultAllow in permission logic and handler
Updated CheckPermissionWithContext to respect the DefaultAllow flag
in PolicyContext. This enables "Open by Default" behavior for
unauthenticated access in zero-config environments. Added a targeted
unit test to verify the logic.
* s3api/s3tables: propagate DefaultAllow through handlers
Propagated the DefaultAllow flag to individual handlers for
namespaces, buckets, tables, policies, and tagging. This ensures
consistent "Open by Default" behavior across all S3 Tables API
endpoints.
* s3api: wire up DefaultAllow for S3 Tables API initialization
Updated registerS3TablesRoutes to query the global IAM configuration
and set the DefaultAllow flag on the S3 Tables API server. This
completes the end-to-end propagation required for anonymous access in
zero-config environments. Added a SetDefaultAllow method to
S3TablesApiServer to facilitate this.
* s3api: fix tests by adding DefaultAllow to mock IAM integrations
The IAMIntegration interface was updated to include DefaultAllow(),
breaking several mock implementations in tests. This commit fixes
the build errors by adding the missing method to the mocks.

Replace the custom suffix-only wildcard implementation in matchesActionPattern
and matchesPrincipal with the policy_engine.MatchesWildcard function from
PR #8052. This enables full wildcard support including:
- Middle wildcards: s3tables:Get*Table matches GetTable
- Question mark wildcards: Get? matches any single character
- Combined patterns: s3tables:*Table* matches any action containing 'Table'
Benefits:
- Code reuse: eliminates duplicate wildcard logic
- Complete IAM compatibility: supports all AWS wildcard patterns
- Performance: uses efficient O(n) backtracking algorithm
- Consistency: same wildcard behavior across S3 API and S3 Tables
Add comprehensive unit tests covering exact matches, suffix wildcards,
middle wildcards, question marks, and combined patterns for both action
and principal matching.
