Multi-provider rebalancing: AWS-scope gate, scope AWS-locked helpers, non-AWS eval cases (v0.6.4)

[hxddh]

StorageOps serves all S3-compatible object storage (AWS S3, MinIO, Baidu BOS, Alibaba OSS, Tencent COS, GCS), not only AWS. A self-review of v0.6.0–v0.6.3 found the recent deterministic helpers leaning AWS-specific (the IAM/notification validators) even though the multi-provider scaffolding (detect_domain provider signatures, provider-quirks/, provider-differences references, the 5-provider ETag matrix) stayed intact. This release corrects the lean and adds a guardrail so it can't grow back silently.

1. New deterministic gate — provider_scope_check.py (wired into CI)

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 — the same lever used for orphan references in v0.6.3. The genuinely multi-provider helpers (--provider on multipart-ETag, throttle-tuning, access-log) are exempt by construction. Unit-tested (4 cases).

2. Scoped the three AWS-locked helpers honestly

notification_config_analyzer.py, notification_target_policy_validator.py, and cross_account_access_validator.py now:

• declare AWS-specific in their docstrings,
• emit "model": "aws" in every result, and
• point at the provider-differences reference (OSS RAM / COS CAM / BOS differ).

Their SKILL.md "Run when" lines note the AWS model too. The honest move is to scope them, not to fake BOS/OSS/COS support we cannot verify — consistent with the project's "mark unverified, don't universalize AWS" stance.

3. Rebalanced the eval corpus with non-AWS cases

So the regression gate stops over-fitting AWS phrasing:

• bos-multipart-etag-leading-dash — Baidu BOS leading-dash multipart ETag mistaken for corruption → data-consistency
• oss-sigv4-region-required — Alibaba OSS SigV4 signing-region mismatch → s3-protocol-compatibility

Each with a baseline; both verified to route correctly via detect_domain (routing-corpus top-2).

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.

Redact the Authorization sample for validation

In the new golden case, this line still matches SECRET_PATTERNS in golden_case_validator.py (Authorization ... AWS4-HMAC-SHA256 \S+). I ran python skills/storageops-eval-golden-cases/scripts/golden_case_validator.py skills/storageops-eval-golden-cases/cases, and it fails on this file before the baseline eval step in .github/workflows/ci.yml, so the added case will make CI red until the header is further redacted/renamed or includes an allowed example marker.
