+    "_comment_extensions": "extensions:[] makes every fork child run with `pi --no-extensions`. This is a CAPABILITY FLOOR, not a style preference: the mempalace bridge is a pi EXTENSION, so with [] a fork physically cannot file drawers or diary entries under your identity. Measured on mbp-m1-2020 2026-09-01 and 2026-09-06: forks ignored their brief, answered in the user's voice, fabricated self-referential measurements, and one filed a diary entry as agent_name=pi (landing in wing_pi, where a wing-scoped diary_read never sees it). Root cause is upstream and by design, not a bug to wait out: the child is handed getHeader()+getBranch(), i.e. the WHOLE active session branch, with the brief appended as the final user message and the system prompt untouched (pi-fork src/index.ts) - so in a long session the parent narrative outweighs the task. Proven by control: the SAME model as the 'fast' profile below (haiku, thinking off) obeyed the identical brief perfectly when run as `pi -p --mode json --session-id <fresh> --no-extensions`, i.e. with no inherited context. COST of []: no palace search and no recall inside a fork. Set to null to restore normal extension loading.",
