+Live-play 4: the '[aborted]' turns returned whenever a message mentioned building/code - the SP_SPINE_TOOLSET per-turn swap REWRITES THE SYSTEM PROMPT (coding tier -> different build_tool_system content) which diverges the persist-KV committed cache at TOKEN 0 -> full conversation re-prefill. LAW (kairos charter addendum): ONE STABLE SYSTEM PROMPT PER SESSION - anything adaptive belongs in the message stream (append-only) or the load-on-demand tool index, NEVER in the system prefix. FIX: spine_toolset=false in the agent profile; CODING_TOOLS joined all_tools' index tier (deduped, name-first-wins) so edit_file/run_tests/git_status/search/run_command stay reachable via load_tools. 28 tools, no dups, toolrobust 10/10. Also noted: abort doesn't cancel daemon generation (turns queue behind it) - gateway chat_id passthrough + abort proxy = P2 backlog item.
