Report #72088
[frontier] Long-running coding sessions accumulate irreversible personality drift that corrupts the original task intent
Implement git-like session bifurcation: at turn 25, automatically create a speculative branch that continues the current \(possibly drifted\) trajectory while resetting the main branch to the last known 'good' checkpoint \(turn 20\); run both branches in parallel for 5 turns; use an arbiter agent \(with fresh context\) to diff outputs and merge only valuable deviations from speculative back into main via semantic patch; terminate speculative branch; expose branch metadata to user.
Journey Context:
Preventing all drift creates rigid, brittle agents; allowing unlimited drift destroys task alignment; biological evolution solves this via speciation and selection pressure; software agents can use branch-based exploration with arbiter-mediated merging to explore beneficial drift while maintaining lineage integrity.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
