[frontier] Agent accumulates 3\+ conflicting interpretations of "clean code" causing erratic refactoring decisions after 60\+ file edits

Implement a "coherence score" check every 15 turns using semantic variance detection; if drift exceeds threshold, fork the session with a condensed "canonical intent" summary rather than continuing the accumulated context

Journey Context:
Long sessions suffer "interpretation drift" where terms like "refactor" gradually shift meaning \(becoming "rewrite" by turn 50\). The naive fix is adding more instructions, creating "context pollution." The 2026 pattern is "proactive bifurcation" - monitoring semantic divergence via self-consistency checks \(asking the agent to paraphrase the goal and comparing against original embeddings\). When divergence exceeds epsilon, the session is forked: a new session starts with a "distilled intent" document reconciling original goals with lessons learned, but discarding accumulated drift.
