Trim
Reduces an always-on LifeOS context file that is over its byte budget via a human-gated pass — deterministic GC of stale entries first, then semantic merges and relocations — never dropping a directive and committing every change reversibly. USE WHEN /trim, trim the context, trim OPERATIONAL_RULES, this file is too big, reduce a doctrine file, context file over budget, file is NN% full, statusline file went red, prune an always-loaded file, shrink CLAUDE.md or DA_IDENTITY. NOT FOR general code refactoring, trimming video/audio (use Video/AudioEditor), or removing AI writing patterns from prose (use _WRITING).
