feat(reports): preserve grouping comparison cross-share delta for serialized successor - #831
Conversation
…(v2.53.0) Caption persisted leftover-map cross share x = 2R̂U/R² on grouping comparison leftover-pair buttons through formatLeftoverMapCrossShare (ADR 0296). Distinct aria-label Leftover map comparison cross share. Missing or non-finite x omits that badge and keeps s, e, R̂, d, and coverage notes. Do not invent x from R̂, U, and R. Finite negative share is shown, never clamped. UI-only; no new columns.

Parent-first/capacity finding: this PR is Ready while its base #829 remains an unmerged feature prerequisite and the live leftover-map foundation is still #802 with #811 Draft/conflicting. Preserve the cross-share delta and evidence, but this descendant has no current protected-main merge path. Return it to Draft so the prerequisite lane remains the only active validation lane; do not close, squash, or discard its ADR/product delta.

Current-head stack-authority finding: live base already equals #829 exact 118500f73251eaaf717d5329b8fb6d9895196fe7, but the PR body still cites obsolete parent 4d82c28, predecessor verification, and historical retarget guidance. Preserve ADR 0296/product semantics and Draft state; make live parent/head/evidence authoritative and do not transfer predecessor tests.

Current-stack finding: #830 has been reopened because its distinct comparison-axis-singular delta was previously closed without merge or verified succession. This PR can no longer treat historical #829 as its final parent authority or ADR0296/v2.53.0 as reserved. Preserve the cross-share delta, stay Draft, and reconstruct after exact promoted #830 with a then-unclaimed ADR/release identity. Do not bypass the recovered valid delta or transfer historical verification.

Fresh exact-head acceptance exposed a valid inherited-fixture compatibility failure rather than a product-path regression. Tests run 34548940024 completed with frontend GREEN and the PostgreSQL/full suite at 1 failed, 1796 passed, 147 skipped; the sole failure was backend/tests/test_report_ingestion_unexplained_share.py::test_fetch_period_comparison_transports_persisted_unexplained_share, where the older _ComparisonConnection fixture omitted the newly read leftover_map_cross_share key and therefore raised KeyError before exercising its unexplained-share assertion. Minimum causal repair 8d7d8fe17de30ef08121d9f38fb1e7279e64354a adds only leftover_map_cross_share: None to that inherited fixture, preserving all product logic and cross-share semantics. Current-head Tests run 34551951853 has been admitted separately; predecessor GREEN is not transferred. Merge remains gated on current-head terminal repository/security checks, independent approval, and rendered browser/a11y evidence.

Review
5172835438established that the comparison action did not carry persistedleftover_map_cross_sharethrough the real period-comparison payload. The repaired source selects persistedlp.leftover_map_cross_share, serializes it through_finite_float_or_none(), preserves finite positive/zero/negative values, maps null/NaN/+Inf/-Inf toNone, composes the same formatted persisted value into the actionable pair name, hides the duplicate visual badge from the accessibility tree, and exercises a signed authenticated fixture. It does not create a second translation authority.Primary-report resilience successor integrated

The repository has a Playwright E2E suite (

No predecessor GREEN transfers across parent movement.#831 is intentionally Draft again: #830 remains a Draft prerequisite, and the exact-head browser/a11y interaction evidence required for this material UI delta is not yet present. Do not spend another repository-local runner lane merely to re-prove the already-GREEN unit/integration/build receipts. The next executable acceptance work is to make the existing Playwright contract exercise this grouping-comparison path through an authenticated product stack and obtain exact-head desktop/responsive keyboard/focus plus pointer/touch evidence without duplicating canonical
.githubowner functions. Only then promote parent-first and merge normally. At protected-main integration require the live organization ruleset, qualifying independent approval, security receipts and release evidence. No self-approval, bypass, synthetic status, force push, destructive rebase, ancestor skip, or stale evidence transfer.
