What

• Add LangSmith OTLP layers for an explicit project or registered agent/environment, with redacted credentials and the existing shared telemetry flusher.
• Classify native model operations once, preserve reported compatibility-provider usage, and keep wrapper spans and planned tool batches out of inference totals. Existing content-capture consent remains in force.
• Store optional task trace parents in format 16 and restore ancestry for initial and queued executions across processes. Existing start retries retain their first committed parent; old journals remain readable. Custom Tasks adapters rerun the extended conformance kit.

Checks

• Repository typecheck, Foundry self-check and demo: pass, zero findings.
• bun test: 3,588 pass, 4 environment-dependent skips, 0 fail; 17,699 assertions across 306 files.
• Package build and packed Node/Bun consumers: pass, including local OTLP classification/usage and fresh-process task ancestry checks; all prior recovery fixtures pass.
• Generated docs: clean, stored format 16 with 40 shapes; format history 1–15 and all eight prior fixture sessions remain exact.
• Website: 15 pages checked, all internal links resolve.
• Models proxy checks on Bun 1.3.6: 46 pass, 2 environment-dependent skips, 0 fail.

Local HTTP collector and fresh-process journeys verify emitted telemetry and task ancestry. Live LangSmith ingestion and paid provider calls have not been verified.
