Security Hardening Mode rejects unauthenticated metadata GETs, so fetch a short-lived token first and fall back to IMDSv1 only when allowed. Co-authored-by: Cursor <cursoragent@cursor.com>
Rename the factory access-type string from ali_cloud to alicloud.

Review summary
Full independent review: isolated clone, full test suite (22 pass / 1 skipped live-e2e, 3x flakiness check clean), CI green (3/3 checks), CodeRabbit ledger verified, and the Alibaba STS signing cross-checked against the akeyless-go-cloud-id PR #22 baseline (RPC-style canonicalized query, double percent-encoding, HMAC-SHA1, query-only POST with empty body). Change is purely additive (new alibaba.js module + one new dispatch branch in cloudid.js); no existing provider path (aws_iam/azure_ad/gcp/access_key) is touched — no BC-break risk.
Signing implementation matches the Go baseline: sorted RPC query params, HMAC-SHA1 with secret + '&', requestUrl built as query-only https://sts.aliyuncs.com/?... with sts_request_body empty — same shape empirically verified against the real STS endpoint for the Go port.
⚠️ Important improvement (please fix before merge)
alibaba.js:143-166(metadataRequest) — the responseIncomingMessage(res) has noerrorlistener. If the ECS metadata HTTP response stream errors or closes mid-transfer, the returned promise can hang or Node can raise an unhandlederrorevent and crash the process. This was flagged by CodeRabbit and is still unaddressed. Fix: addres.on('error', reject)and reject on aclosebeforeendfires (guard so the promise settles exactly once), and add a mock test case for both.

- IMDSv2 support for ECS RAM-role credentials (
alibaba.js) — Valid, already fixed (commit ee91bae); current code implements PUT/latest/api/token+X-aliyun-ecs-metadata-tokenon both metadata GETs with IMDSv1 fallback. No action needed. metadataRequestunhandled stream error/incomplete close (alibaba.js:150-151) — Valid, still open — see Important improvement above.cloudid.js:21"acceptali_cloudper PR objective" — Invalid. Org-wide check (akeylesslabs/akeyless-main-repo—client/config/profile.go: ALICLOUD AccessType = "alicloud", CLI usage strings acrossauth.go/configure.go, gateway docs) confirms"alicloud"(no underscore) is the canonical access-type string used everywhere in the ecosystem, matching this PR and the PR's own description (getCloudId("alicloud")). CodeRabbit's premise about anali_cloudobjective doesn't match the actual convention — no change needed.- Outside-diff comment: add

💡 Suggestions (non-blocking)
alibaba.jsalibabaQueryEscape/buildAlibabaRpcStringToSign: the per-param encoder doesn't map*→%2A(only the outer string-to-sign pass does), and the+→%20round-trip before the second encoding pass is a slightly indirect way to get double-encoding right. It produces byte-identical output to the documented Alibaba RPC signing spec for every value this code actually signs (hex nonce, ISO timestamp, fixed enum strings, access key/security token), so it's not a functional bug today — but it's fragile if a future param could contain*,+, or~. Consider consolidating into one well-testedpercentEncodehelper.cloudid.e2e.test.js:10doc comment forAKEYLESS_CLOUD_ID_E2E_TYPEdoesn't listalicloudas an option — minor doc gap, e2e file only.
Test/CI status: node --test 22/22 pass (1 e2e skipped, expected offline), re-run 3x with no flakiness; both GitHub "JS Tests" checks and CodeRabbit status are green.
Treat truncated or errored metadata streams as failures, keep response newlines so the first RAM role is used, and encode STS query params with a single Alibaba percentEncode helper. Co-authored-by: Cursor <cursoragent@cursor.com>

Full independent review from scratch: isolated clone, built and ran the full suite with JDK 11 (matching CI) — 44 tests pass, 4 skipped (gated live-e2e), 0 failures, stable across 3 reruns of the Alibaba suite. CI green (3/3 checks). Signing algorithm cross-checked line-by-line against the approved akeyless-go-cloud-id PR #22 baseline: RPC-style canonicalized query string (sorted params incl. empty SignatureType), double percent-encoding via a single unified percentEncode helper, HMAC-SHA1 with secret+"&", query-only POST with empty body to https://sts.aliyuncs.com/ — matches exactly, including a golden hardcoded-signature unit test (rpcStringToSignIsDeterministic).
BC check: change is purely additive — new AlibabaCloudIdProvider + one new "alicloud" branch in CloudProviderFactory. No existing provider path (aws_iam/azure_ad/gcp) touched, CloudIdProvider interface unchanged. Cross-repo check confirms "alicloud" matches the canonical server-side access-type value in akeyless-main-repo (client/config/profile.go ALICLOUD AccessType = "alicloud").
Previously-flagged bug verified fixed: commit 0e840b0 rewrites readFully() to copy the raw InputStream (ByteArrayOutputStream) instead of readLine()-based concatenation, preserving newlines so firstLine() correctly isolates the first RAM role from a multi-line ECS metadata response. Covered by a direct regression test (readFullyPreservesNewlinesAndRejectsTruncation) and an end-to-end test against a mock multi-line metadata server (ecsCredentialsUseFirstRoleWhenMetadataIsMultiline). The same commit also fail-closes on truncated/errored metadata streams (content-length mismatch and IOException both now throw, previously ignored) and fixed a latent inconsistency where the request URL's query encoding didn't apply the same +/*/~ normalization as the signature string.
CodeRabbit ledger: both open threads (IMDSv2 token hardening, readFully newline handling) are resolved and independently re-verified against current code — no unaddressed comments remain.
No blockers or important improvements found. Approving.
