Vyomi v2.6.0

Parity Finish — closes the rest of docs/PARITY-GAPS.md after v2.5.0: all of
P2 (operation depth), all of P3 (cross-cloud symmetry), and the tractable P4 net-new
data planes. Every op lands in the shared substrate-free cores, so Nano gains them
too; each is proven by a conformance test.

Added — operation depth (P2)

• S3 multipart upload (Create/UploadPart/ListParts/Complete/Abort; canonical
  md5(concat part-md5s)-N ETag) + GCS resumable upload (session URI + finalize).
• DynamoDB GSI query (CreateTable persists index KeySchema; Query(IndexName=…))
  • Firestore richer structuredQuery (comparison / IN / ARRAY_CONTAINS /
    compositeFilter AND·OR / orderBy / limit).
• SQS FIFO (MessageGroupId ordering + content dedup) + DLQ redrive; SNS
  filter policies (per-subscription delivery filtering).
• KMS rotation (Enable/Disable/GetKeyRotationStatus/RotateKeyOnDemand) + Secrets
  Manager RotateSecret; Azure Key Vault wrap/unwrap + sign/verify.

Added — cross-cloud symmetry (P3) & net-new data planes (P4)

• Azure SQL data plane (azure_sql_core) — real SQL on the SqlStore seam, the
  RDS / Cloud SQL peer.
• Azure RBAC decision core (azure_iam_core) — a checkAccess evaluator
  (wildcard actions, notActions, scope inheritance, explicit-deny-wins), the AWS
  SimulatePrincipalPolicy / GCP testIamPermissions peer.
• EventBridge event-bus (eventbridge_core) — rules + event patterns → SQS
  delivery; wired into the router (AWSEvents.* JSON wire).
• Lambda serverless invoke (lambda_core) — function lifecycle + a synchronous
  Invoke that runs the handler in a sandboxed Python runtime (no
  import/open/eval; errors → X-Amz-Function-Error); wired into the router.

Verified

• Live native-SDK sweep vs the running unified ingress: S3 + SQS green
  end-to-end on real backends. The DynamoDB live-403 was root-caused to the
  tier-licensing gate (nosql → Max tier, by design) and the Azure-Blob live-404
  to the running container serving pre-v2.5.0 code (current code returns
  201/200) — neither an ingress defect.

Deferred (documented, not shipped as stubs)

• API gateway + VPC data planes (each a dedicated-release-sized subsystem).
