bug(plugin-detail): a percent summary chip states two different percentages — its text and its own bar are computed by different rules #8728
Description
Found while implementing objectui#8464 (the summary chip's object-value display). ⛔ Not fixed there — a different defect on the same lines, filed rather than ridden along.
What
packages/plugin-detail/src/DetailView.tsx, the effectiveSummaryFields.map render beside the page H1. The percent branch computes its TEXT and its BAR from the same number by two different rules:
display = `${num}%`; // the text
const normalized = num <= 1 ? num * 100 : num; // the bar
percentValue = Math.max(0, Math.min(100, normalized));
So for a stored 0.123 the one chip states two different percentages at once: the label reads 0.123% and the bar beside it fills to 12.3%.
Measured
Rendered DetailView with summaryFields: ['ratio'], fields: [{ name: 'ratio', type: 'percent' }], data: { ratio: 0.123 }, on ed971e8fc:
| what | value |
|---|---|
| chip text | 0.123% |
chip aria-label |
ratio: 0.123% |
| bar fill width | 12.3% |
what PercentCellRenderer prints for the same value |
12% |
The last row is the cross-band half: the body grid and the highlights strip draw 12% for the value the chip calls 0.123%.
Not ruled
Which of the two the chip should follow is a product question — PercentCellRenderer's rule (and the bar's) treats a value at or below 1 as a ratio; the text treats it as an already-scaled percentage. Whoever takes it should decide once and make the text and the bar read the same number, rather than fixing one of them.
Dedup
Run. Channel: MCP search_issues (repo-scoped REST /search/issues is refused in this container — "sessions are bound to their configured repositories"). Its control fired on the same session: a query for the summary-chip object-value defect returned objectui#8464 itself as the top hit, so this is not a false zero. Query summary chip percent text disagrees with its progress bar ratio stored value detail header returned one closed, unrelated item (objectui#4596). No duplicate found.

DetailViewis published, and the chip's rendered text changes for every storedpercentvalue at or below1— input it accepts today. Same class as the prior pairs in this lane.⭐ CORRECTED PRACTICE on

"branch": "claude/issue-8728-percent-chip-one-rule",
"pr": "#9072",
"premise_still_valid": true,
"summary": "The card's premise held: the chip really did compute its text and its own bar from one stored number by two rules, and a stored 0.123 rendered '0.123%' beside a bar at 12.3%. Fixed by one named function, packages/plugin-detail/src/summaryChipPercent.ts, that both halves read, so they cannot desynchronise again without a call site being deleted; the surviving rule is the BAR's, per the ruling, so every bar this chip has ever drawn is byte-identical and the text is what moved. ZONE 2 A RESOLVED: FALSIFIED — the bar's rule is LOCAL, not the repo's. 'num <= 1 ? num * 100 : num' is the only spelling of its kind in packages//src and apps//src; percentDisplayValue in @object-ui/core is the declared single source of truth (its doc comment requires any third surface to take BOTH halves from it) and uses the symmetric 'value > -1 && value < 1', and formatPercent/PercentCellRenderer, plugin-dashboard/recordFields and plugin-grid/useColumnSummary all reach that boundary. So this PR closes a two-way disagreement sitting inside a three-way one, and the PR body says so in a census table. EXACTLY 1: answered 100% on this chip — not a preference but the bar's existing answer, which the ruling says the text must follow — and PINNED as its own test row rather than left incidental, with the disagreement stated in the PR body: every other band in this repo renders a stored 1 as '1%', and objectui#5607 already settled that boundary in words when it removed the same drift shape from plugin-dashboard. The convergence and the fork it decides are filed as objectui#9071. One consequence recorded rather than buried: a stored value at or below -1 now reads '-500%' where the text alone read '-5%' (the bar is unchanged, negatives clamp to an empty track either way) — the same asymmetry objectui#9071 is about. CLAUSE-2: needs:contract-review hung on BOTH carriers additively (REST POST, http 200 each, confirmed on a delayed re-read); 'check-clause2-carriers.mjs --pair 9072' EXIT 0 — 'the clause-2 declaration is readable in the fixed spelling and both carriers agree'. objectui#8729's defect was seen in the same render and left alone per the serial ruling. No assignee was set at any point.",
"tests": "All runs from the repo root, paths relative to it, nothing after a bare double-dash. (1) TARGETED: 'pnpm exec vitest run packages/plugin-detail/src/tests/summaryChip.percentOneRule-8728.test.tsx packages/plugin-detail/src/tests/summaryChip.objectValue-8464.test.tsx' -> exit 0, 'Test Files 2 passed (2)', 'Tests 32 passed (32)'. (2) DECLARED NARROWING: the 17 files in plugin-detail that mount DetailView or exercise a percent value -> exit 0, 'Test Files 17 passed (17)', 'Tests 234 passed (234)'. The full 118-file package suite is NOT MEASURED: the shared heavy-verify lock was held by the sibling worktree objectui-issue-8632 across FOUR acquisition attempts (exit 99 each, VERDICT queue-timeout, holders 'pnpm exec vitest run --maxWorkers=2 packages/app-shell/' held up to 1295s, then 'pnpm --filter @object-ui/console run test'); queue place kept under slot objectui-8728-dev throughout. (3) NOT MEASURED: 'pnpm --filter @object-ui/plugin-detail type-check' — it needs 'pnpm --filter @object-ui/plugin-detail^... build' first (a fresh worktree has no dist/*.d.ts for the 12 workspace peers; without it tsc reports TS2307 for every @object-ui import, which is a missing build and not a type error), and that closure build is exactly what the held lock serialises. (4) GATES: 'node scripts/check-changeset-presence.mjs' exit 0 — its own verdict line: '2 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s)'; 'pnpm run check:control-bytes' exit 0 (7256 tracked text files); 'check:new-line-citations' 0 new citations; 'check:unreferenced-sources' OK, every shipped source file reachable — the gate that sees the new module; 'pnpm --filter @object-ui/plugin-detail lint' exit 0 (985 pre-existing warnings, 0 errors). Exit codes were captured before any pipe, and each verdict is quoted from what the gate itself printed. ABLATION, predicted in writing before running: mutation = the committed one-rule branch in DetailView.tsx replaced on disk by the pre-fix two-rule form, helper and both test files left as committed; the tests import '../DetailView', a relative specifier inside the same package, so the mutated SOURCE ran — no dist, no package exports, no vitest alias, so no missing build could hide it. Mutation and restore proven by blob hash, not by exit codes: HEAD blob 9f918f8a94b19c388eacb5d5827629c86717afec, on-disk before EQUAL (tree was at HEAD), on-disk after e24d61c54aca14e202cc49a61fa634db1bf04989 (differs, so the mutation landed), injected-text grep 1 and removed-text grep 0, after restore EQUAL again with 'git diff HEAD' empty; the script carried a trap on EXIT INT TERM with absolute paths and restored with 'git checkout HEAD --', never a bare checkout. Predicted red: the 0.123, exactly-1, 0.07 and -5 rows, the whole-table agreement test, and the updated pin in summaryChip.objectValue-8464.test.tsx — six. Predicted green on both legs: the 12.3 CONTROL, 0, 1.5, 250, the non-numeric string row, and the accessible-name test (both of its halves read the same 'display' string, so it cannot see this defect, which is why it is not the pin). Measured: 'Tests 6 failed | 26 passed (32)', and the six were exactly the six predicted. Restored leg re-run: 'Tests 32 passed (32)'.",
"mcp_calls": "2 — issue_write (to file objectui#9071) and create_pull_request. Everything else went through zero-quota channels: the card, its triage comment and the PM claim came from the public-repo webpage payload, and every other read and write (label additions, label re-reads, PR body readback, the dedup sweep, this comment) went through repo-scoped REST, probed green first.",
"open_questions": [
{
"question": "The dispatch's ruling 2 ('make the TEXT follow the BAR's rule; do not change the bar') rests on a premise the census falsified — that 'num <= 1 ? num * 100 : num' is the repo's interpretation of a stored percent. It is this file's only. Obeying the ruling therefore fossilised a drifted copy for one more release and moved the chip's TEXT for stored values at or below -1 from correct-per-core ('-5%') to '-500%'. Flagging the conflict rather than picking a side silently, per the standing contract.",
"options": [
"A — what shipped: obey the ruling exactly (text follows the bar, bar untouched), pin every boundary answer including exactly-1 as 100%, and file the convergence as objectui#9071. Two-way disagreement closed, three-way one disclosed and carried.",
"B — converge here instead: both halves call percentDisplayValue. Everything improves except that the bar's fill at exactly 1 changes from 100% to 1%, which the ruling forbids; and the doc comment it converges onto demands BOTH halves (scaling AND convention), and the convention half would break the dispatch's own required control (formatPercent renders a stored 12.3 as '12%' at the default precision), so a partial adoption would itself be a fourth dialect.",
"C — hybrid: the bar's upper arm with core's lower arm, so no rendered bar changes anywhere and the text never regresses. Rejected: it is literally the third rule the ruling forbids, and it would be my invention rather than any decision the repo has taken."
],
"recommendation": "A, which is what shipped — the ruling is binding and its contingency for exactly this case (Zone 2 A: 'this card fixes a two-way disagreement inside a three-way one, and the PR body must say so') is explicit. The residue is carried by objectui#9071 with the census, the quoted contract, the objectui#5607 precedent and three costed routes, so the decision is a PM/maintainer call on a card rather than a guess in a diff. If the seat would rather have B, objectui#9071 is the place and the exactly-1 row in the new test is the single line that has to move."
}
],
"out_of_scope_findings": [
"filed as objectui#9071: the chip's percent scaling is a drifted copy of percentDisplayValue — census table of all five sites, the doc comment's own 'any third surface takes BOTH halves from here' contract, the objectui#5607 precedent that settled exactly-1, the third convention the WRITER uses (PercentField reads the field's declared max instead of guessing from magnitude), and three costed routes. Class (b), a declared contract broken, quoted. Dedup ran on repo-scoped REST over all 101 open domain:ui issues with a control that fired (the sweep returned objectui#8728 itself); scope boundary stated on the card.",
"noted, not filed: objectui#8729's defect (the chip names its field by the raw column name) is live in the same render and was left untouched per the serial ruling. Carrier: objectui#8729 itself. The new test asserts only the percentage half of the accessible name, so that card keeps a free hand over the field-name half.",
"noted, not filed: packages/plugin-grid/src/useColumnSummary.ts spells core's boundary inline instead of calling percentDisplayValue. Same boundary, same answers — a duplicate, not a drift, so it is not a defect today. Carrier: objectui#9071, whose census table already names it.",
"noted, not filed: Number(true) is 1, so a percent field storing a boolean lands on exactly the ambiguous input. No authored percent field in this tree stores a boolean and this PR changes none of the guards in front of the branch. Carrier: objectui#9071, which decides which authority that branch reads."
