feat(reports): preserve grouping comparison axis-singular delta for serialized successor - #830
Conversation
…rip (v2.51.0)
Caption persisted leftover-map singular values on GET /api/reports/compare/{period} through leftoverMapCompareAxisSingular (ADR 0294). Distinct aria-label Leftover map comparison axis singular. Omit missing, non-finite, or negative leftover-map singular value independently of leftover-map comparison axis share. Do not invent leftover-map singular value from leftover-map axis share. No SQL. No leftover score or theta.

Recovery finding: this closed-unmerged PR still owns a distinct grouping-comparison axis-singular product delta, and exact current #824 does not contain frontend/src/leftoverMapCompareAxis.ts. Closing it therefore did not satisfy the valid-delta succession rule. The PR is reopened as Draft; preserve the feature but treat historical ADR0294/v2.51.0 and old base as evidence only, then reconstruct after the current serialized descendants with a live unclaimed identity.

Fresh review finding: #829 has already moved non-force to 0e4fd5815686120ec66203cb6848834b56bdf289, so the historical #830 head cannot be treated as current-parent evidence even though its axis-singular delta is still valid. I refreshed the PR base to exact #829 and started automation/830-current-829-reconstruction-r1-20260907-1758@2fd79f5eb0308abb272139fb87ba79863310cbb9 / run 34103171306. That lane first requires a real Vitest RED for missing persisted singular-value behavior on exact #829, then reapplies only the one-commit e7913761...ef5fcf63 source/test delta with three-way conflict reporting and a focused GREEN. No product ref moves unless a later current-parent lane obtains complete causal/release/governance GREEN.

Current-parent diagnostic r1 is a valid RED but not a valid reconstruction. Exact #829 0e4fd5815686120ec66203cb6848834b56bdf289 passed the authority check, and the realistic formatter test failed as expected because leftoverMapCompareAxisSingular is absent. Replaying the entire historical e7913761…ef5fcf63 child delta then conflicted in LeftoverPairList.tsx, i18n.test.ts, i18n.ts, leftoverMapCompareAxis.ts, and leftoverMapPlotLayout.ts; those conflicts are stale cumulative-history conflicts, not evidence that current #829 is defective. The historical App/App-test/backend-serialization hunks applied cleanly. Repair should therefore preserve only the independent persisted-singular contract: current leftoverMapCompareAxis.ts gains a finite/non-negative formatter that preserves zero, current grouping-strip rendering computes share and singular independently, and only the clean serialization/render regressions are adopted. Do not replay the conflicted i18n/list/plot-layout files or create a second translation source; eight-locale authority remains #922/#929/#932. Candidate identity remains ADR0370/v2.56.0 after rechecking that no open PR currently claims ADR0370. Product head must stay historical until that minimal current-parent reconstruction has an exact-head GREEN and can be promoted non-force with historical #830 first parent and exact #829 second parent.
Repair the reconstructed #830 release identity without reusing historical ADR 0294 / v2.51.0. Keep the decision Proposed, synchronize Python/frontend package versions, and record the persisted axis-singular product contract.

Current-head governance repair finding and resolution: the reconstructed product delta had advanced to c6f9654... while still inheriting predecessor ADR 0369 / v2.55.0. I added a persistent RED contract first (aa54b5e...) requiring an unclaimed Proposed ADR 0370 and synchronized v2.56.0 identity; exact predecessor state failed that contract because ADR 0370 did not exist. The causal follow-up 8f6e17c7... adds only ADR 0370, a v2.56.0 changelog fragment, and synchronized pyproject.toml / lineageweave.__version__ / frontend package versions. ADR 0370 remains Proposed and preserves fast-mlsirm psychometric ownership plus #922/#929/#932 translation-ledger ownership. The feature still is not merge-ready: hosted exact-head PostgreSQL/frontend/Storybook and current-head browser/a11y evidence remain required.

Current-parent repair finding verified after #829 moved to 07301271f813b8bb0e40f57aa22373baf5efbf01. Do not reuse historical #830 GREEN. GitHub's live three-way merge preserves the overlapping backend/tests/test_api.py assertions additively; candidate 4c71c0679fa5fa1cde6807e43b5002346ada5875 uses that exact clean tree with historical #830 as first parent and exact #829 as second parent. Product ref stays at b36b2534... until current-parent validation is terminal GREEN. If it passes, promote only non-force and immediately converge #831.

Current-parent review found one material a11y defect in the reconstructed #830 tree before promotion. The new singular badge sets a generic aria-label="Leftover map comparison axis singular", so accessible-name computation replaces the visible axis/value text and hides σ_k from assistive technology. The current test explicitly accepts four identical generic labels, so it cannot catch value loss. Repair this on the exact #829 reconstruction lane before product-ref movement: add a regression requiring the singular badge's accessible text/name to retain axis + persisted formatted value (including 0.00), then make the badge expose that value rather than a generic replacement label. Do not alter psychometric computation or couple singular visibility to axis-share validity.

Refinement of review 5135527493 after checking the current W3C WAI-ARIA/APG naming guidance: these badges are plain <span> elements with the implicit generic role, and generic is name-prohibited. The defect is therefore stronger and simpler than merely having a duplicated name: #830 should not put aria-label on the singular badge at all. Keep the localized visible tf(LEFTOVER_MAP_COMPARE_AXIS_SINGULAR, comparisonAxisSingular) content as the AT-readable text, remove the singular badge's prohibited naming attribute, and replace the current getAllByLabelText("Leftover map comparison axis singular") regression with assertions over the rendered axis/value text plus current-head accessibility/browser evidence. Do not add role just to legalize an unnecessary name, and do not change psychometric computation. W3C APG Accessible Name Guidance by Role classifies generic as Prohibited for naming.
The grouping comparison singular badge is a generic span. Remove the prohibited aria-label and assert the persisted σ_k text instead.

#830-specific repair evidence
Earlier current-parent validation isolated two local defects: ADR0370 named a stale predecessor, and the singular-value badge put an unnecessary author
aria-labelon a plain<span>. The bounded repair tied ADR0370 to its then-current parent, removed only the singular badge's prohibited naming while preserving visible localized persistedσ_k, and kept singular/share visibility independent. Validation head4c93e91..., run34171114817, was terminal GREEN for frontend lint/tests/build/Storybook and the complete PostgreSQL-backed suite.
