fix(diagnostics): adopt the documented transport_phase vocabulary#8964JulienAu wants to merge 21 commits into
Conversation
First slice of the correlated outbound diagnostics facility: a shared managed_transport_failure event schema with seven connection-ordered phases, an allowlist-only builder, a safe error-cause-chain walker that drops free-text messages, credential and query stripping for endpoint references, a bounded content-type-aware error-body snippet, a strict response-header allowlist, deterministic phase classification over the undici and socket vocabulary, and failure-only key=value emission with a generated correlation id. A non-MCP webhook consumer test proves the contract is reusable beyond the first integration. Negative tests cover every forbidden field class. Refs NVIDIA#7957 Signed-off-by: JulienAu <16043912+JulienAu@users.noreply.github.com>
The advisor's PRA-1 blocker is right: the formatter wrote allowlisted header values and required string fields as raw key=value text, so a delimiter- or credential-bearing upstream value could forge a second record or leak. Route every emitted string through encodeLogField, which redacts through the shared trace sanitizer, bounds length, and JSON-quotes any value carrying a control character, whitespace, quote, or separator. Add a formatter test with newline, CRLF, forged-field, and credential-shaped values proving one-record, no-leak output. Refs NVIDIA#7957 Signed-off-by: JulienAu <16043912+JulienAu@users.noreply.github.com>
Addresses the advisor's PRA-2 blocker: redaction happened only in the line formatter, so an alternate consumer serializing the built event could disclose a credential embedded in an operation, route, consumer name, or allowlisted header. Redact every untrusted string field in buildManagedTransportFailure so the returned object is safe by construction; emission encoding stays as defense in depth. Also select the first cause-chain code for the top-level cause_code so a wrapped transport error surfaces its network code (advisor PRA-1 correctness). Refs NVIDIA#7957 Signed-off-by: JulienAu <16043912+JulienAu@users.noreply.github.com>
Addresses the advisor's PRA-3 blocker and trace-id warning: copied error names, codes, and syscalls are now bounded identifier tokens (anything longer or carrying other characters becomes <invalid>), and a supplied trace id is kept only when it matches the safe id shape, falling back to a generated one otherwise. The built event stays safe to serialize regardless of what an upstream library or caller puts in error metadata. Builder tests cover credential-shaped and delimiter-bearing cause fields and trace ids. Refs NVIDIA#7957 Signed-off-by: JulienAu <16043912+JulienAu@users.noreply.github.com>
…ippet Addresses both advisor warnings on the managed-transport failure contract. PRA-1: buildManagedTransportFailure accepted an error body with no condition on the HTTP status, while boundedErrorBodySnippet documents non-2xx capture only. A caller could therefore attach the body of a successful response to failure diagnostics and retain response content the module promises not to keep. The snippet is now carried only when httpStatus is present and outside 200-299. An absent status is not treated as a failure status either: a transport error that never produced a response has no body to capture. PRA-2: the emitter serialized errorBodySnippet with JSON.stringify while every other field went through encodeLogField. JSON.stringify quotes and escapes, so it prevented record forging, but it neither redacts nor bounds. An event object constructed directly rather than through the builder could therefore carry a credential-bearing snippet straight into diagnostic output, bypassing the build-time redaction boundary. The snippet now goes through encodeLogField like everything else. encodeLogField takes an optional bound so the snippet keeps its documented 512-character limit rather than being truncated to the 256-character field limit. Two regression tests, both verified to fail without their fix: a builder test asserting a 200 response with a textual body yields no snippet and does not serialize its content, and an emitter test passing a hand-constructed event whose snippet carries a bearer token and a forged event line, asserting the credential is absent, the record count is unchanged, and no newline escapes. 20 tests pass in normal and shuffled order. Biome check and the src typecheck are clean; the two pre-existing banner.ts errors about an unbuilt nemoclaw/dist artifact reproduce identically on an unmodified tree.

Request changes at exact commit 49479c1daa88f078561773fe4c9f37444b5a4d72.
Two blockers remain:
- Architecture and documentation: #8725 still has a maintainer changes-requested decision requiring one canonical direction. The public OpenClaw dependency review says the injected helper remains the source of truth and the reusable source schema is deferred until a production consumer needs it. This PR adds that unused parallel schema without an accepted maintainer decision, and its wire vocabulary still differs from the active patch for
response_server/server,response_via/via, andcause_chainserialization. The alignment tests cover only part of the wire contract. - Security:
safeTargetRef("user:secret@second-secret@host:8080?token=x")returnssecond-secret@host:8080, so malformed non-URL userinfo can reach the built event and emitted log. Strip through the last@or reject the value, and add proxy, target, event, and emitted-record tests.
Do not add public documentation for a dormant contract. First obtain the repository-owned architecture decision. If the dormant schema is accepted, update the dependency review to describe the source-of-truth relationship and align or explicitly scope every wire field. #8725 is not confirmed superseded and should remain open.

Reviewed current head debc957d9a5d96db73fb4bbed69ce3b741c6c83b.
The latest change correctly redacts every target userinfo segment before the final @; the earlier exposure is fixed. The PR remains blocked at the product/architecture gate:
src/lib/diagnostics/managed-transport.tsadds a 363-line production contract with no production importer.- The PR body explicitly says the module has no production importer and treats documentation plus a source-reading test as its current consumer. Documentation and tests are not production consumers.
- #7957 and #8725 do not establish an accepted delivery slice for this parallel contract. The independent documentation review at this exact head is therefore correctly recorded as
blocked. - Current required CI also fails in the CLI lane.
Do not land the dormant contract as canonical behavior. Please obtain a maintainer scope decision naming the production consumer and lifecycle, or move the independent proposal through Community Solutions. Once scope exists, use one production-owned wire contract rather than a source-reading compatibility assertion between parallel schemas.
Security review: redaction now passes; no new authentication, authorization, cryptography, dependency, or injection issue remains in the current diff. System design and verification remain blocked because the contract is not connected to production and its CI is failing.

Review of commit debc957d9a5d96db73fb4bbed69ce3b741c6c83b: this PR is not approval-ready.
The transport-phase vocabulary is introduced without an active production importer, so the schema and tests describe a dormant contract rather than behavior exercised by NemoClaw. The branch also conflicts with current main, and cli-test-shards (3), cli-tests, and the aggregate checks job fail.
Rebase or merge current main only if the conflict resolution is behavior-preserving, identify the production consumer that owns this contract, and rerun the complete required test and review gates. If no current production consumer exists, close this change rather than adding an unused compatibility surface.

Summary
Sequential follow-up to #8725 (slice 1 of #7957), addressing the architecture
review on that PR: one canonical wire vocabulary for managed-transport
diagnostics instead of two. The in-process contract has no production importer
yet, while the OpenClaw managed transport dist patch's field names are already
public:
docs/reference/troubleshoot-mcp-servers.mdxtells users to readtransport_phasefirst, and the dependency review pins the vocabulary withtests. So the contract adopts the patch's documented names, and a new
contract test reads the patch source so a future divergence fails in CI.
phasebecomestransport_phase, andsession_id_presentbecomes
session_present, matching the patch and the troubleshooting guide.proxy_connectbecomesconnect, the value the patchclassifier returns and the dependency review documents.
response_streamstays as a seventh value for consumers that classify failures after response
headers arrive; the patch never emits it, so no conflict.
trace_iddeliberately keeps its name: the dependency review states that thepatch's
diagnostic_idis a local identifier that does not correlate acrossprocess boundaries, while
trace_idis the cross-boundary correlation fieldof this contract. A test asserts the contract never emits
