Report #31484

[synthesis] Agent overwrites its own task directive in context after ingesting verbose tool output \(e.g., logs\), causing goal drift

Architecturally separate immutable 'Task Context' \(system prompt area\) from mutable 'Scratchpad'; enforce a token budget allocator that summarizes tool outputs >50 tokens before injection, requiring explicit user confirmation for overwrite of task parameters.

Journey Context:
The ReAct pattern \(Thought -> Action -> Observation\) is susceptible to 'Observation' payload size. When an agent runs \`git log\` or \`find\`, the output can be hundreds of tokens. Appending this raw output to the context window pushes the original 'Task: refactor function X' downward in the attention stack. In subsequent iterations, the 'Thought' process no longer references 'function X' because it is no longer in the high-attention region of the context; instead, it focuses on the log entries. This is 'context poisoning by volume'. Simply increasing context size doesn't help because attention mechanisms still favor recent tokens. The architectural fix is to treat the original user intent as 'sacred' \(locked in the system prompt or a protected preamble\) and all tool outputs as 'ephemeral' that must pass through a summarization filter before being visible to the reasoning loop.
