Description
Translate one supplied reach-space coordinate and compare to a supplied boundary.
Activity and assistive-task records distinguish planned, attempted, completed, assisted, observed, and optional components. Shares depend on the selected denominator and credit policy. A supplied code, geometry, or time-budget calculation is separate from evaluating an individual's function or safe access.
Translate one supplied reach-space coordinate and compare to a supplied boundary.
When to use this tool
Use Reach Space Origin Shift Budget when you need this specific task-count, assistance-code, timing, equipment-budget, or participation-record component.
How to use the tool and how it works
- Enter reachCoordinate, originShift, boundaryCoordinate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read newCoordinate, remainingMargin. Use the output convention below.
Return newCoordinate=reachCoordinate-originShift and remainingMargin=boundaryCoordinate-newCoordinate.1

| originShift | Origin Shift | Required. Finite number. |
| boundaryCoordinate | Boundary already expressed in the shifted coordinate frame. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| newCoordinate | New Coordinate | Required. Finite number. |
| remainingMargin | Remaining Margin | Required. Finite number. |

}Limitations and assumptions
- All coordinates need one length unit and the boundary must already use the shifted frame. The tool does not transform the boundary, model a reach envelope, or determine functional reach capacity or safe workspace access.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the intended assessment and a complete task or access model when a local check is insufficient. Verify task definitions, credit policies, measurement units, and the context of the underlying observations.
