* fix(agents): describe unrecorded tool results as unknown outcomes
Use shared unknown-outcome guidance while preserving the Responses-family aborted convention. Retain synthetic provenance in model context so late real results can replace repair placeholders without changing existing detection or stored transcript rows.
* improve(agents): assert provider request history stays append-only
Track converted message prefixes and record declared compaction, pruning, runtime-context, and image rewrites. Notify every cache-affinity baseline for the same session identity. Memoize message/content and schema fingerprints, with strict assertions enabled only by an opt-in environment flag.
* fix(agents): pin the shared tool-result text for the request wrapper
Include packages/llm-core/src/types.ts in the PR wrapper's extracted source inventory. Main commit 93625aa3d1 pulled tool-result-pairing.ts into that graph, so its existing shared tool-result text import must be included for standalone wrapper execution.
