Chalky Paper Vinegar Test Sensitivity Flag
Audit independently supplied prior paper-test evidence, not vinegar handling advice or authentication. Missing observations remain explicit. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.
Description
A prior paper-test response may be recorded and compared with a reference for chalky-paper review.
A prior paper-test response may be recorded and compared with a reference for chalky-paper review.1
This checker evaluates supplied values and known flags; it does not instruct the user to carry out a physical or chemical test.
When to use Chalky Paper Vinegar Test Sensitivity Flag
Use this tool when you need to review known observations against explicit inclusive bands. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
How to use Chalky Paper Vinegar Test Sensitivity Flag and understand its results
- Prepare independently verified observations, reference edition/context, and matching units or currency basis.
- Enter observedExistingPaperTestResponse, callerExistingPaperTestResponseLower, callerExistingPaperTestResponseUpper, knownExistingPaperTestResponseFlags, following the field table and calculation rules below, then run the tool.
- Read signedKnownMargins, knownReviewIndices, unknownIndices. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedExistingPaperTestResponse | Observed existing paper test response | list of number | Required |
| callerExistingPaperTestResponseLower | Caller existing paper test response lower | list of number | Required |
| callerExistingPaperTestResponseUpper | Caller existing paper test response upper | list of number | Required |
| knownExistingPaperTestResponseFlags | Known existing paper test response flags; binary 1 means assessed and 0 means unknown. | list of number | Required |
Enter nonempty aligned observed values, caller lower/upper bounds, and binary known flags. Require lower≤upper for every row, even an unknown one. For a known value return min(value−lower,upper−value): positive inside, zero on a boundary, and negative outside. Only known values strictly outside the inclusive band enter knownReviewIndices. Unknown rows receive a zero placeholder and their separate unknownIndices, so an unknown zero margin is not passing evidence.
margin_i=known_i?min(observed_i−lower_i,upper_i−observed_i):0 Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedKnownMargins | Minimum signed distance to the two inclusive bounds for known observations; zero placeholder for unknown observations. | list of number |
| knownReviewIndices | Zero-based input positions that are known and strictly outside the inclusive reference band. | list of number |
| unknownIndices | Zero-based input positions without a known observation; inspect before interpreting zero placeholders. | list of number |

}Limitations and assumptions
The observation method, units, and appropriate bounds come from the supplied records. Unknown observations remain unassessed, and numeric band agreement does not authenticate an item or establish a certified grade.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Numeric values must be finite; nonfinite numeric outputs are rejected. Arrays must be dense, with no missing cells. Numeric lists allow at most 10000 entries, subject to smaller tool-specific bounds above.
Alternative or Complementary methods
For a related task, use Paper Type Identifier Wove versus Laid Detector: Wove and laid paper structures refer to different paper patterns that must be observed in context. This detector compares supplied evidence with caller classes instead of scanning a specimen or applying a physical test. For a complementary step, use Fluorescence Response UV Long-wave Classifier: Paper fluorescence under longwave ultraviolet illumination is a measured response that depends on the observation basis and reference conditions. This tool reads a supplied response curve at a query coordinate rather than identifying paper from a photograph.
