WalkthroughManaged tool execution now accepts optional external tool-call IDs. Core lifecycle events preserve the ID across FFI, Go, Node.js, and Python APIs, including framework middleware and success, failure, cancellation, and rejection paths. ChangesManaged tool-call correlation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to This change adds optional managed tool-call correlation IDs while preserving existing behavior when omitted; no actionable merge-blocking risk remains after normal checks and review.

the field is absent when no external tool-call ID is supplied, not null. Apply
the same absent-field semantics to the identifier relationship definition at

**/*.{md,mdx,rst}: Use title case consistently for technical documentation headings and table headers; avoid quotation marks, ampersands, and exclamation marks in headings, while preserving official product, event, research, and whitepaper title case.
Format code elements, commands, parameters, package names, expressions, directories, file names, and paths in monospace; represent path placeholders with angle brackets inside monospace.
Format UI buttons, menus, fields, and labels in bold, and separate consecutive UI navigation labels with>.
Use quotation marks for error messages and strings when appropriate, italics for newly introduced terms and publication titles, and plain text for keyboard shortcuts.
Represent GitHub repositories with owner/repository link text, such as[NVIDIA/NeMo](link), rather than generic repository wording.
Introduce every code block with a complete sentence; do not let a code block complete or interrupt the grammar of surrounding prose; use syntax highlighting when supported.
Keep inline method, function, and class references consistent with nearby documentation; omit empty parentheses in prose when no call is shown.
Use descriptive link text matching the destination title when possible; avoid raw URLs, generic anchors, long-sentence links, and unnecessary links that distract from procedures.
Ensure lists have a complete lead-in sentence, more than one item, no more than two levels, parallel construction, one idea or action per item, and appropriate punctuation; use bullets for unordered items and numbers for ordered tasks.
Format definition lists with a bold term followed by a complete, parallel, punctuated definition.
Use tables for reference information, decision support, compatibility matrices, and comparable choices; flag one-row tables, missing captions or lead-ins, sentence-case headers where title case is expected, unexplained empty cells, and code or links that would be clearer as prose.
Write procedure steps as imperative ...

Learning: When adding/adjusting Go unit tests for `BuildCacheRequestFacts` (request-ID validation and related request parsing), set `CacheRequestFactsInput.Provider` to a valid provider in all tests that are intended to isolate request-ID behavior—because `BuildCacheRequestFacts` does not validate `Provider`. Then add separate test coverage for malformed `AnnotatedRequest` JSON so JSON parsing failures are not conflated with `Provider`-related inputs.

Do not locally reclassify this as `PluginError::Conflict`; changing the classification requires a core-wide review of the public API and FFI behavior.

Learning: In NeMo Relay (RELAY-509), sanitizer callback failures must be treated as intentional fail-open behavior. When an event/tool (request/response) or LLM (request/response) sanitizer callback fails, the sanitizer chain should retain and publish the last valid event/payload snapshot (rather than dropping/invalidating the data) and log the failure including callback context (e.g., which sanitizer/callback failed and relevant identifiers). Apply this consistently across all sanitizer chains mentioned in the RELAY-509 documentation/migration guide.

Any session-close or teardown path (e.g., the OpenClaw live smoke session-close flow) must await `flushSubscribers()` before continuing to live ATIF export assertions and before teardown, so queued subscriber delivery fully completes and tests/assertions observe the final state.

Overview
Manual tool-call lifecycle APIs can carry a provider-assigned
tool_call_id, but managed execution could not accept one. Consequently, a framework, harness, or transport could not preserve an upstream invocation ID into Relay's managed tool Start and End lifecycle events. On currentmain, Pythontools.execute(..., tool_call_id="…")raisesTypeErrorbecause that parameter is absent.This PR adds an optional external tool-call correlation ID to managed execution across Rust, Python, Node.js, C FFI, and Go. A provider, harness, or transport can now supply one stable ID at the managed execution boundary, and Relay places that ID on the matching tool Start and End events across success, callback error, and cancellation.
This closes the remaining managed-execution runtime gap in the tool-provenance direction described by #446:
This PR is rebased on current
mainand builds on #575. Relay continues to expose transport-neutral primitives rather than owning MCP transport or adding a protocol-specific proxy.Details

Start with
crates/core/src/api/tool.rsand the managed lifecycle regressions incrates/core/tests/integration/middleware_tests.rs. They show the central behavior for success, failure, cancellation, omission, and guardrail rejection.Then review
crates/ffi/src/api/tool_lifecycle.rswithcrates/ffi/nemo_relay.hfor the additive C ABI decision, andpython/nemo_relay/integrations/langchain/middleware.pyfor framework ID forwarding. The application/protocol responsibility boundary is documented indocs/integrate-into-frameworks/wrap-tool-calls.mdx.Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to)
