Cameron resolved the wire-law session's open call: a proposed link auto-routes through known constructed runs and the route sheet offers the meaningfully different candidates (corridor vs crawlspace) with their real signature consequences; commit pins the exact route. Freehand drawing is rejected. Unknown runs never surface as candidates. Defense: docs-only design capture. building.md's route-selection clause moves from [OPEN - decision-required] to DECIDED with the rule stated once; the decision volume records history without owning it; DEVLOG.md is regenerated, not hand-edited. No crates/ change.
