Summary

Preserve separately supplied tool.execution_complete.data.structuredContent in the full unified session, alongside the existing primary output view. This fixes the loss of typed Goose shell stdout, stderr, and exit_code observed in seven completions across the conformance run and the smoke run.

• Add the optional JSON-compatible field to canonical and unified types and regenerate both schemas.
• Retain nested JSON, Unicode/escaping, and explicit empty/falsy values without restoring provider envelopes or compact MCP RPC response bodies.
• Apply existing registered-secret and structural-redaction rules to the new payload; correlation metadata remains protected.
• Add sanitized projection/serialization regressions and direct native-shape assertions through Goose canonical and raw-log collection. Update the session specification and changeset.

Validation

• Reproduced the bug before the fix: 11 targeted regression failures.
• Focused projection, Goose, and generated-schema suites: 344 tests passed.
• make fmt-cjs, make lint-cjs, and TypeScript typecheck passed (lint reports existing warnings, no errors).
• make agent-report-progress passed: build, changed-file lint, schema freshness, TypeScript checking, and 266 impacted JavaScript tests. No Go changes; impacted Go tests were correctly skipped.
• A pure local projection of the original captured agent artifacts preserves all seven previously dropped structured results, without altering their output arrays.

Evidence limits

No workflow dispatch, new inference, MCP startup, or credential changes. The captured artifacts are existing live Actions evidence; projecting them locally is not a new hosted verification. Neither sampled run contained reasoning, failed tools, or subagents, so those live mappings remain unverified. Existing published artifacts are not rewritten.

🟡 Changes recommended

The default serializer does not redact registered secrets in object keys, allowing retained structuredContent keys to leak secrets into usage/aw_session.jsonl.

What changed in this PR

This PR preserves separately supplied structuredContent alongside primary tool output in gh-aw’s unified sessions, retaining typed Goose shell results for downstream consumers.

Changes:

• Add the optional field to canonical and unified types, schemas, and projection.
• Extend payload-redaction handling and add retention, serialization, and Goose regressions.
• Document the behavior and add a patch changeset.
