- LlmEvent::Usage across all three providers (Scripted deterministic
word-count accounting; Anthropic message_start/delta usage; OpenAI-compat
stream_options include_usage)
- tc-billing: ceil(tokens/1000) min 1 credit; lots drain oldest-first under
FOR UPDATE; balance clamps at zero while the usage ledger records the
full obligation; promo codes redeem exactly once via CAS (migration 0006)
- Runtime charges every completed run (billing failure never fails a run);
proven: 1 token in + 3 out -> 1 credit deducted
- API: GET /api/team/usage, POST /api/credits/redeem (409 on reuse, audited)
- Credits page: balance, 7-day usage meter with runway estimate, PromoRedeem
- /claws/new is the full §9 wizard: ?step=identity|access|slack deep-linked
progress, accent swatches + name randomizer, access toggles, optional
Slack step, explicit review-and-confirm (creation = live agent), animated
provisioning state -> straight into chat
- E2E: chat decrements the visible balance and fills the usage meter;
WELCOME500 adds exactly 500 once then refuses; wizard round trip
140 Rust + 63 frontend tests + 23 Playwright journeys.
