Overtime Pay Check

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Verify overtime pay for a workweek in two stages: FLSA regular-rate and overtime premium computation per 29 CFR 778 (ART-340), then a session receipt aggregating the run's execution hashes (CRY-05). Federal weekly 40-hour rule only; state daily overtime rules are out of scope. Not legal advice.

Note: art-340 rounds the regular rate to cents before computing the premium, so results can differ by one cent from payroll systems. A nondiscretionary bonus is treated as earned in the workweek entered; bonuses covering several weeks must be prorated before entry.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: I earn $20/hour, worked 45 hours this week, and got a $100 performance bonus. What is my overtime pay?
Run the AINumbers MCP tool `run_chain` with {"chain":"overtime-pay-check"} and read `art-340-compute-flsa-regular-rate.overtime_premium_pay`.
Re-run with `inputs` for `art-340-compute-flsa-regular-rate`, reusing the values that result echoed, with `hours_worked_week` set to 50. Compare the same field.
Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`.
Ledger, for a human re-check: https://ledger.ainumbers.co/
PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
