A dataset measure cannot render as a percent: the console's scale heuristic reports a rate of exactly 1 as 1.0% #101

Description

@os-warren

Found while adding duly_duty_health.on_time_rate in #52. The rate ships as a bare fraction (format: '0.00'0.94) because every percent spelling is either inert or wrong at the one value that matters most.

Measured, in the browser, against the demo's 0.94

measure formattile renders
(absent)0.94
'percent'1
'0.00'0.94 — what ships

'percent' is the obvious spelling and it is silently wrong. The console treats format as a numeral pattern, not a keyword (@object-ui/core, utils/dataset-format.ts#formatMeasure): decimals come from format.split('.')[1]?.match(/0/g)?.length ?? 0, and percent mode turns on only for a literal %. So 'percent' means "zero decimals, not a percent", and 0.94 rounds to 1.

Why '0.0%' is not the answer either

Percent mode scales by a heuristic, because a measure — unlike a field — has no declared percentScale to hand:

exportfunctionpercentDisplayValue(value: number): number{returnvalue>-1&&value<1 ? value*100 : value;}

A ratio of exactly 1 is outside that window, so a 100%-on-time period renders as 1.0%. The function's own docblock records the same defect for fields (objectui#3136), which was fixed there by letting the server declare the scale — DatasetMeasureSchema has no such key, so the fix did not reach measures.

An on-time rate of 1.0 is not an edge case: it is the number a small tenant sees most often, and the one a customer is proudest of. Reporting it as 1% is the worst available failure.

What would close it

A dataset measure needs to say that its value is a fraction — the same thing percentScale: 'fraction' says for a field. Then format: '0%' on a derived ratio would be safe and this app would show 94% / 100% instead of 0.94 / 1.00.

Two halves, and they live upstream:

  1. @objectstack/specDatasetMeasureSchema gains the annotation (it is z.strictObject, so an app cannot pass one through today).
  2. objectuiformatMeasure already prefers a declared scale over the heuristic; it just needs the measure's.

Filed here rather than upstream because I could not verify which upstream repo owns the pair from this checkout. Worth re-filing as objectstack-ai/objectstack + objectstack-ai/objectui when someone can.

Not blocking

duly_duty_health reads 0.94 today under a tile titled "On-time rate", with the denominator stated in its description. Unambiguous, and never a wrong number — just not the 94% it should be.

                      A dataset measure cannot render as a percent: the console's scale heuristic reports a rate of exactly 1 as 1.0% #101

                      Description

                      @os-warren

                      Found while adding duly_duty_health.on_time_rate in #52. The rate ships as a bare fraction (format: '0.00'0.94) because every percent spelling is either inert or wrong at the one value that matters most.

                      Measured, in the browser, against the demo's 0.94

                      measure formattile renders
                      (absent)0.94
                      'percent'1
                      '0.00'0.94 — what ships

                      'percent' is the obvious spelling and it is silently wrong. The console treats format as a numeral pattern, not a keyword (@object-ui/core, utils/dataset-format.ts#formatMeasure): decimals come from format.split('.')[1]?.match(/0/g)?.length ?? 0, and percent mode turns on only for a literal %. So 'percent' means "zero decimals, not a percent", and 0.94 rounds to 1.

                      Why '0.0%' is not the answer either

                      Percent mode scales by a heuristic, because a measure — unlike a field — has no declared percentScale to hand:

                      exportfunctionpercentDisplayValue(value: number): number{returnvalue>-1&&value<1 ? value*100 : value;}

                      A ratio of exactly 1 is outside that window, so a 100%-on-time period renders as 1.0%. The function's own docblock records the same defect for fields (objectui#3136), which was fixed there by letting the server declare the scale — DatasetMeasureSchema has no such key, so the fix did not reach measures.

                      An on-time rate of 1.0 is not an edge case: it is the number a small tenant sees most often, and the one a customer is proudest of. Reporting it as 1% is the worst available failure.

                      What would close it

                      A dataset measure needs to say that its value is a fraction — the same thing percentScale: 'fraction' says for a field. Then format: '0%' on a derived ratio would be safe and this app would show 94% / 100% instead of 0.94 / 1.00.

                      Two halves, and they live upstream:

                      1. @objectstack/specDatasetMeasureSchema gains the annotation (it is z.strictObject, so an app cannot pass one through today).
                      2. objectuiformatMeasure already prefers a declared scale over the heuristic; it just needs the measure's.

                      Filed here rather than upstream because I could not verify which upstream repo owns the pair from this checkout. Worth re-filing as objectstack-ai/objectstack + objectstack-ai/objectui when someone can.
