# Exact supported time-series grid composer

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Compose an aligned grid from supplied nonoverlapping piecewise-constant segments with exact rational integrals, means over supplied support and source contribution durations.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- resample piecewise-constant time series to an exact aligned grid
- calculate time-weighted means over explicit supplied support
- compose exact rational series cells with missing-support evidence

## Outside this profile
- Interpolation, zero filling, extrapolation or last-observation carry-forward
- Overlapping segments within one series or undeclared measurement validity
- Floating-point approximations, display rounding or inference of observation quality
- Accessing calendars, scheduling jobs, reserving meetings, network requests or external state changes

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
