claude pool accounts never showed reset credits in the usage panel. the hub read /api/oauth/usage with a claude-code/2.1.273 user agent, and claude only returns reset grants (cedar_ember) when you pass ?cedar_ember=1 with a current claude-cli/<version> (external, cli) agent. an old version gets ineligible_reason: "cli_version", anything else gets "surface"

what changed
• hub reads claude usage with ?cedar_ember=1 and the installed claude code version (highest enabled claude instance in the provider registry), then maps grants with the existing claudeResetCreditsToContract
• redeem works for claude hub accounts now: looks up the org from /api/oauth/profile, posts to /api/organizations/{org}/reset_rate_limits, then clears the hub cooldown like codex already does
• request id is a uuidv5 of account + grant so a retried click cant spend a grant twice

tradeoff: one request id per account + grant. every grant ive seen has resets_total: 1 so thats fine, but if claude ever packs 2 resets into one grant the second would come back already_used. native macos instances still skip reset credits (token lives in keychain), but the row merge already takes credits from the hub so pooled accounts are covered

live read of my pool on this branch: cathedral 2, max.f 2, maschwenk 4 (one full weekly reset each plus the fable launch resets)
