* 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. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * 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. --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
