Failed CommandExecution items are ignored by the item_completed handler, so the matching tool observation can remain at DEFAULT even when Codex records a failure.

Read failed / declined completions and fill the existing tool call's error by exact ID. Exclude user_shell, preserve existing errors, output, and timing, and leave legacy completion handling unchanged. Unmatched IDs do not create tools or propagate errors to a code-mode wrapper; cross-turn completions remain out of scope.

Tests

• Cover failure-detail fallbacks, declined calls, unrelated IDs, user-shell events, non-failure states, existing errors, and cross-turn isolation.
• Verify the original exec is ERROR without mislabeling a later write_stdin call.
• pnpm run lint and pnpm test pass (136 tests).
• Bundled Stop hook → local OTLP receiver: verify error attribution, sidecar writes, and repeat-Stop deduplication. The error-level assertion fails on unmodified v0.4.3.

The new tests do catch the bug. With the parent versions of parse.ts and types.ts, 5 of the PR's new tests fail; with the head versions, they pass.

I ran pnpm --config.manage-package-manager-versions=false exec vitest run plugins/tracing/test/parse.test.ts plugins/tracing/test/trace.test.ts on the head three times: 76 passed each time. Then I reverted only parse.ts and types.ts to the parent version (the tests stay at head) and ran the same command three more times: 5 failed, 71 passed each time, and the same 5 failed every run. Those are the four records CommandExecution cases and the trace.test.ts ERROR-level test. The other 71 tests pass on both versions.
