[synthesis] Context window pressure causes selective amnesia of early constraints leading to version drift

Inject critical constraints \(e.g., library versions, target OS\) into the system prompt or a persistent scratchpad, and implement a pre-execution validation gate that checks the generated code against a static dependency manifest before running it.

Journey Context:
Agents operating over long trajectories suffer from attention decay on early tokens. An agent instructed to use Library v2 will eventually forget, write v3 code, and encounter runtime errors. The compounding failure occurs because the agent sees the runtime error, misdiagnoses it as a code logic bug rather than a version constraint violation, and rewrites the logic using v3 paradigms, cementing the error. Relying on the agent to remember constraints across a 100k-token context is fundamentally flawed due to transformer attention mechanisms.
