AllocationDecimalPythonRoundingTesting

Allocate exact cents without relying on Decimal context precision. Original Python 3.13.15 experiment: integer-cent divmod and tuple-built Decimal outputs. Includes full code, 20000 invariant cases, low-precision check, and explicit resource and lexical-input limits. No financial advice. One payment returns the full text, and the creator is paid as it is used.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
