[core] Two more sites carry the bare `27,581 of 1,200,013` percent figure with no grid named, so it still reads as a discrepancy against #4590's 27,577

[os-sales]

Observation-class. No runtime behaviour, no failing assertion. Recorded while implementing objectui#4596, whose declared surface was exactly two files.

Background

Two measurements of the same phenomenon exist, both correct:

• objectui#4576 (PR fix(core): one home for the number-display policy — and percent stops drifting between cell and measure (#4576) #4589): 27,581 of 1,200,013 ordinary-magnitude en-US forms move on a tie-dense grid, measured on formatMeasure / formatDisplayNumber's call shape.
• objectui#4590 (PR fix(fields): formatPercent renders points directly — ties round half-up and extremes keep every digit (#4590) #4595): 27,577 of 1,200,003, the same grid description (0.005 steps to 2,000, precisions 0/1/2) re-measured through formatPercent.

The counts differ because the call shapes differ, not because either is wrong. Note that naming "the grid" alone does not separate them — both cards describe the grid identically. The disambiguator is the surface measured.

objectui#4596 attached that qualification to the two comments inside its fence. Two further live sites carry the bare figure and were out of that fence:

• packages/core/src/utils/number-display.ts:118 — the DisplayNumberFormatOptions.style doc comment: "27,581 of 1,200,013 ordinary-magnitude en-US forms move".
• packages/core/src/utils/__tests__/number-display.percent-points.test.ts:96 — "Measured: 27,581 of 1,200,013 ordinary-magnitude en-US forms differ between the two routes."

Both are accurate. Neither says which grid or which call shape produced the number, so a reader who has also seen packages/fields/src/index.tsx:503 or packages/fields/CHANGELOG.md still meets two counts that look like a contradiction — which is the reading objectui#4596 set out to stop.

Why this is a line and not nothing

Same reasoning objectui#4596 gave for its own two sites: a figure a reader cannot reconcile is what makes a correct comment get distrusted wholesale. This is cheap to close and the correct form is already written in objectui#4596's PR (#5606) for the two sites it covered — the wording can be lifted.

Explicitly not in scope

The CHANGELOG.md entries in packages/core, packages/i18n and packages/fields also carry these figures. Those are historical release records and should not be edited — they were accurate as published.

Suggested size

XS, prose only. Two comment lines, zero executable change; a .changeset with empty frontmatter is the declaration form (packages/core/src/** is released source, so the presence gate does require the declaration).
