Report #59505

[synthesis] Agent re-attempts previously failed solutions because the summarization of past context dropped the root cause of the failure

Maintain an out-of-band, unsummarized failure ledger that explicitly stores Action -> Observed Error -> Root Cause tuples, injecting this ledger into the active context at every turn.

Journey Context:
Standard RAG and summarization treat all tokens equally. But in debugging, why something failed is higher entropy than what was tried. Agents loop because they see the same error state and retrieve the same initial solution. Developers try increasing context, but eventually, summarization is needed. The synthesis of MemGPT context management and the Reflexion pattern reveals that summarization must be asymmetric: aggressively compress successes, but never compress the specific error messages or root causes of failures. A persistent failure ledger breaks the amnesia loop.
