Report #53844

[frontier] Time-bound instructions \('use staging API until Friday'\) persist past expiration or expire prematurely due to summarization

Tag each instruction with a TTL \(time-to-live\) timestamp and implement a 'timekeeper' middleware that filters expired constraints before prompt assembly, storing expired instructions in a 'graveyard' for audit but never injection

Journey Context:
Static prompts cannot handle temporal validity. The frontier pattern \(emerging in production LLM ops 2025\) is treating instructions as ephemeral configuration with explicit lifecycle management, similar to TLS certificates or feature flags. The hard-won insight is that instruction validity is a temporal concern that must be handled by middleware, not the LLM, to prevent 'zombie constraints' \(expired but still active\) or 'ghost constraints' \(prematurely forgotten\).
