[synthesis] Agent operates on stale environment state due to desynchronized internal memory

Never rely on the agent's internal scratchpad as the source of truth for system state. Always inject the current state \(e.g., file contents, directory structure\) via a fresh observation step immediately before any state-mutating action.

Journey Context:
Agents often read a file, plan a series of steps, and then execute them. But if the environment changes \(e.g., another process modifies the file, or the agent itself ran a formatter that changed line numbers\), the agent's internal memory of the state is stale. It will confidently apply diffs to the wrong lines or overwrite changes. People try to fix this by making the agent 'remember' better, but LLMs are stateless approximators. The tradeoff is the cost of re-reading state vs. the risk of overwriting. Re-reading is always correct because the cost of a single state check is orders of magnitude less than recovering from a corrupted file.
