Day-job machines shed zero exposure; crimson comes only from THINK states (Operations at start, Research locked). The first-think beat: same-tick dust, highlighted off-toggle, afford-reveal on the camera claim. Amends the 2026-07-08 heat-everywhere clause. Defense: design capture amending wiki/mechanics/machine-work.md (byproduct clause, WORK/THINK grammar, 'The first think' section, criteria 3/9); no src change in this work order — the now-violating DAY_JOB_EXPOSURE_PER_TOKEN removal is dispatched under ROADMAP #33.
