Use when this tick or session hit real, disproportionately costly friction with the harness (a pitfall it could have warned about, a slow gate, missing operational knowledge), touched structural debt it can't fix right now (a duplicate surface, a hand-roll a sanctioned crate already covers), or can ground an apply-ready diff — to the harness's operating layer, or advocating a process-phrase re-cut — in a named invariant. Files one terse capture to .flume/friction/, .flume/refactor/, or .flume/amendments/ in the documented format — exceptional, never a duty; most ticks file nothing.
Verifies the checklist summarizer end to end: runs it against TODO.md and compares the printed count with the file's items. Use after changing anything under src/ or TODO.md.
How to add knowledge to this harness: which kind owns a new fact, convention, procedure, or enforcement, and the trigger that says it is time. Use when adding or reorganizing a rule, skill, hook, or memory entry.
Use when driving a complex task through an agent team — parallel exploration across independent axes converging on a shared artifact, with an adversarial reviewer gate. NOT for single-axis or research-only work.
