Quadratic Funding Round Recompute

Recompute how a quadratic funding round splits its matching pool. Plain mode applies the square of the summed square roots. Pairwise-bounded mode weights each contributor pair by M over M plus their overlap. Amounts are integer minor units and every square root is an exact integer root, so the same input always gives the same split. Reproduces the published formula on your data. It does not detect sybils.

Inputs
Plain applies the base formula. Pairwise-bounded needs the constant M below.
A whole number of the smallest currency unit.
Used only in pairwise-bounded mode. A larger M moves the result toward plain mode.
Normalize splits the whole pool. Cap pays the raw subsidy when it fits inside the pool.
Each root is floored at this many decimal digits. Zero to nine.
Use short pseudonymous labels. At most 200 lines, 40 contributors and 20 projects.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `compute_modified_premium`. Task: Apply an NCCI experience modification factor to a caller-supplied subject premium (total manual premium plus premium items subject to experience rating) to get the modified premium, rounded to whole dollars.
Call it with arguments: {"policy_parameters":{"mod":0.9,"subject_premium":10000}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
