Lanes Shipped
A lane is a domain-scoped coder specialty carrying distilled build guidance. Selection picks the single best-matched lane per increment rather than fanning out.
Each lane carries a Build Focus — imperative build guidance curated from roughly 165 cookbook documents — plus an anchored honor-and-cite directive: the coder must name each principle it applied and anchor it to a line in the diff it just wrote. Grounding is two-tier, with the distilled guidance inline and the full guideline bodies read on demand, because dumping everything is what caused a 13.5M-token incident.
Lane selection is deterministic
Signals rank the lanes against the diff so far, with zero model calls in the normal case. Only a genuine tie escalates to exactly one team-lead dispatch, and any failure there degrades loudly to a null lane with the candidates listed — never a silent guess. Cross-domain work splits into consecutive single-lane increments instead of a fan-out.
