From ad78c39359cd78a8b67c98ddbb5d9a30117c783b Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 21 Jun 2026 06:10:49 +0000 Subject: [PATCH 1/2] multi-provider: AWS-scope gate, scope AWS-locked helpers, non-AWS eval cases (v0.6.4) StorageOps serves all S3-compatible object storage, not only AWS. A self-review found the recent deterministic helpers leaning AWS-specific (IAM/notification validators) while the multi-provider scaffolding stayed intact. This corrects the lean and adds a guardrail. - New gate scripts/provider_scope_check.py (wired into ci.yml): flags any helper that hardcodes AWS-only identifiers (amazonaws.com / arn:aws:iam) without being provider-parameterised (--provider) and without an explicit "AWS-specific" scope declaration. Turns silent AWS-lock into a CI failure. Unit-tested. - Scoped the 3 AWS-locked helpers honestly: notification_config_analyzer.py, notification_target_policy_validator.py, cross_account_access_validator.py now declare AWS-specific in their docstrings, emit "model": "aws" in every result, and point at provider-differences (OSS RAM / COS CAM / BOS differ). SKILL.md "Run when" lines note the AWS model. Honest scoping rather than faking unverifiable BOS/OSS/COS support. - Rebalanced the corpus with non-AWS cases so the gate stops over-fitting AWS phrasing: bos-multipart-etag-leading-dash (BOS leading-dash multipart ETag vs corruption -> data-consistency) and oss-sigv4-region-required (OSS SigV4 signing-region mismatch -> s3-protocol-compatibility), each with a baseline. Validation: all gates green incl. the new provider-scope gate; 211 pytest + 21 extension tests; 30/30 baselines 100% PASS; routing-corpus recalls both non-AWS cases. Version 0.6.3 -> 0.6.4.

Replaced it with a credential-free SigV4 scope description that keeps the region evidence (us-east-1 vs cn-hangzhou). Case still routes to s3-protocol-compatibility and its baseline still scores PASS.
