Part four of today's design session. Decided: money flows on the substrate but renders only in ledgers/panels (no coins on chassis); the person visual read is affirmed (gray unaware / crimson attention ramp / amber asset mark). Cameron asked what could be a token; the full taxonomy lands in machine-work.md as PROPOSED: three families — demands in cold signal (Lab day-job drops AND the work you drop on people, forged orders/favors, same token role-reversed), exposure in crimson (heat on machines, attention on people, filings in the Office — one family, three carriers), knowledge in bone (research points, intel recordings, facts) — plus amber-is-never-a-token. Concealment proposed as a sink, not a shipped good; influence tentatively bone-family pending the social-verbs session; money/feeds/messages ruled not-tokens. Defense: documentation-only commit (DESIGN.md + wiki/); no src changes. Same-turn capture; the taxonomy is marked PROPOSED awaiting Cameron's yes/no, decisions are dated in the constitution's log.
