[frontier] Agent personality drifts to match the 'voice' of its own summary artifacts after recursive context compression

Implement 'Identity Anchoring Blocks': freeze the initial system prompt \(containing core personality directives\) in a non-summarized, high-priority context segment that is re-injected at the top of every new context window after summarization. Never summarize the identity block; use a 'prompt checksum' \(e.g., first 32 chars hash\) to verify it hasn't been corrupted during context management.

Journey Context:
The error occurs because when agents summarize their own history, they adopt the linguistic patterns of the summary \(often terse, third-person, or utilitarian\) as their new 'voice'. This is a form of stylistic collapse. Standard practice is to summarize everything to save tokens. The fix recognizes that identity is a 'meta-stable' property requiring constant energy \(token expenditure\) to maintain. Tradeoff: higher token cost for the identity block. Alternative: periodic 'personality recalibration' turns \(ineffective, too late\). This approach treats the system prompt not as static configuration but as a dynamic invariant that must be actively protected from entropy.
