Recommended action: Keep history append-only; inject instructions with mid-conversation system messages instead of editing system/tools; use server-side compaction/context editing. To continue, send anthropic-beta thinking-binding-controls-2026-08-01 and set thinking.block_binding.prefix_mismatch_behavior='drop_block', or strip thinking blocks from the named block onward.
