shankar0123 3a84432eeb Bundle M.Cloud (Coverage Audit Closure): AzureKV + GCP-SM — H-004 closed
Closes the deferred 4th sub-batch from Bundle M; Bundle M is now FULLY CLOSED across all 4 sub-batches.

Coverage:

  AzureKV:  41.2% -> 85.6%  (+44.4pp; +15.6 above 70% target)

  GCP-SM:   43.1% -> 83.4%  (+40.3pp; +13.4 above 70% target)

Engineering: rewritingTransport (custom http.RoundTripper) intercepts

the hardcoded cloud-API URLs (login.microsoftonline.com /

oauth2.googleapis.com / secretmanager.googleapis.com) and rewrites Host

to point at an httptest.Server while preserving Path + Query. For GCP,

the service-account JSON file written to t.TempDir() carries token_uri

pointing at the test server (clean override path).

azurekv_failure_test.go (~280 LoC, 13 tests):

  - getAccessToken: happy + cached-reuse + 401 + malformed JSON +

    empty-token + network-error

  - ListCertificates: happy + token-failure + 5xx + malformed +

    multi-page pagination via nextLink

  - GetCertificate: happy + 404 + malformed JSON

  - New constructor smoke

gcpsm_failure_test.go (~430 LoC, 19 tests):

  - loadServiceAccountKey: happy + file-not-found + malformed-JSON +

    bad-PEM + empty-private-key

  - getAccessToken: happy (JWT-bearer flow) + cached-reuse + 401 +

    malformed + empty-token + load-credentials-failure

  - ListSecrets: happy + token-failure + 5xx + malformed

  - AccessSecretVersion: happy + 404 + bad-base64-payload

  - Name / Type identity

Verification:

  go vet ./internal/connector/discovery/{azurekv,gcpsm}/...    clean

  gofmt -l                                                     clean

  staticcheck -checks all                                      clean (only

    pre-existing ST1005 hits in master, unrelated to Bundle M.Cloud)

  go test -short -count=1                                      PASS

  go test -race -count=1                                       PASS, 0 races
