Summary

  • Persist leftover-map coordinates ξ_{1:2} and ζ_{1:2} on leftover post–criterion pairs after two-axis Gabriel reconstruction (ADR 0267, migration 0245).
  • After make seed, closest and farthest leftover pairs sit above the member list with ξ (x, y) ζ (x, y) next to leftover-map distance d; click opens that post.
  • Rank-0 unused axes store 0.0. A non-finite coordinate omits all four. When coordinates, reconstruction, and distance are finite, R̂ = ξ · ζ and d = ‖ξ − ζ‖.
  • Never invent a leftover score. Never invent a theta. Do not name leftover-map inner product, cosine, or length as separate columns.

Verification

  • leftover + docs: tests/test_leftover_pairs.py, tests/test_documentation_hygiene.py (30 passed)
  • frontend vitest: leftoverMapCoordinates + LeftoverPairList + i18n leftover keys (102 passed); App leftover-pair open (2 passed)
  • tests/test_schema.py and tests/test_period_report.py were not executed here (no PostgreSQL / fast_mlsirm in this sandbox)

Evidence boundary

Authenticated PostgreSQL API and k6 runtime acceptance are not claimed. No real records or credentials. Synthetic fixtures only.

Independent approval is required. No self-approval, admin bypass, or force push.

📝 Walkthrough

Walkthrough

잔여 맵 person/item 좌표를 저장하고 API와 프론트엔드 플롯에 전달합니다. 플롯은 persisted 좌표, 축 공유율, 좌표 눈금, persisted 거리 d를 표시합니다. 누락되거나 비유한 값은 표시에서 제외합니다. 관련 테스트와 문서를 갱신합니다.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 9bdd3

The change can present ambiguous coordinate labels in the leftover-map view, and an incorrectly ordered rollout or rollback could make report reads unavailable. These bounded correctness and availability risks should be fixed or explicitly accepted before merging.

Independent review required on exact head e2d13019004a5d8c019fecf7a39ceeef4093b8dd.

This is leftover-map coordinates ξ/ζ (ADR 0267 / migration 0245 / v2.24.0) onto main. Do not squash-merge without an independent APPROVE on this exact head plus required Checks. No self-approval.

Exact-head ownership audit: this candidate is not merge-ready under accepted ADR 0208. The buyer projection is useful, but residual-map coordinates are owned by fast-mlsirm Rust; its current residual_interaction_map result already returns person_coordinates and item_coordinates. This PR extends the frozen local NumPy debt instead of consuming an accepted, persisted owner artifact. Keep the capability unavailable here until the owner-contract → strict consumer/persistence → shadow-evidence delivery order is satisfied. No heuristic or local numerical substitute.

Cycle retry 2026-08-28 16:05 KST. Exact head e2d13019004a5d8c019fecf7a39ceeef4093b8dd.

Required tests, frontend, ontology, Semgrep, OSV, Trivy, Scorecard, PROV-O, and Noema are green on this head. Strix failed closed (job 98756133389) and OpenCode review failed (job 98757933706). Those are control-plane/reviewer flakes, not a leftover-map coordinate defect. Do not transfer an older Strix success. Do not weaken fail-closed on Vulnerabilities [1-9].

Independent APPROVE is still required. No self-approval, admin bypass, or force push. Squash-merge only after independent APPROVE plus exact-head required success.

Next buyer increment after this lands: leftover-map graphic display (Gabriel 1971 biplot of persisted ξ / ζ), stacked, not mixed into this PR.

Gate inventory (do not merge):

  • Independent APPROVE: still missing. Devin COMMENT only (5047981018). Author will not self-approve.
  • Required success: Full test suite, Frontend lint/test/build, ontology, Semgrep, OSV, Trivy, Scorecard, PROV-O/Noema, coverage-evidence, dependency-review — green.
  • Fail-closed: Strix job 98756133389 failed; opencode-review 98757933706 failed. Do not transfer older Strix success. Do not weaken fail-closed on Vulnerabilities [1-9].
  • Squash-merge only with independent APPROVE + exact-head required success.

Next leftover increment (not this PR): leftover-map graphic display (Gabriel 1971 biplot of already-persisted ξ/ζ). UI-only; no new columns ( and d already are inner product/length). Will land as v2.25.0 / ADR 0268 stacked on this branch, not mixed into dashboard stacks #640/#778/#781 or this coordinates PR.

Requesting Copilot review again on this exact head.

Draw persisted leftover-map coordinates ξ and ζ as a Gabriel biplot
above leftover pair buttons (ADR 0268). Click a post marker to open
that post. Omit the plot when coordinates are missing. No new columns.
Never invent a leftover score or a theta.

Write probe 2026-08-28 cycle: leftover-map graphic display (v2.25.0) is on this head (2f7e9c8). Next stacked increment is leftover-map axis share on the graphic display (ADR 0269 / v2.26.0): caption plot axes with persisted ADR 0148 leftover_map_axes inertia σ_k² / Σ_j σ_j². UI-only, no new SQL, no leftover-score invention. Independent exact-head APPROVE still required before squash-merge; not self-approving.

…787)

Caption leftover-map plot axes with persisted ADR 0148 leftover-map
axis share σ_k² / Σ_j σ_j² (ADR 0269). Rank-0 zero-share axes still
name 0%. A missing or non-finite share omits that axis badge and
keeps the existing leftover-map axis text. Click a post marker to
open that post. No new columns. Never invent a leftover score or a
theta.

Stacked #787 leftover-map axis share on the graphic display (ADR 0269 / v2.26.0) squash-composed into this head (d7a8c2bc). Plot axes now name persisted ADR 0148 leftover-map axis share. Rank-0 zero-share axes still named. Missing/non-finite share keeps existing leftover-map axis text. Click still opens that post. Independent exact-head APPROVE still required; Copilot review ≠ independent APPROVE. Not self-approving. Do not mix into dashboard stacks.

Cycle overlay 2026-08-29 13:15 KST.

Exact head remains 4a0afbf4804d9862bba58869db20ccdfb0a0b37e (v2.24.0 coordinates + v2.25.0 graphic display + v2.26.0 axis share). Auto-merge squash stays armed. Required Checks that completed on this head: Full test suite, Frontend lint/test/build, Semgrep, Trivy, Scorecard, noema-review, coverage-evidence. Strix and opencode-review fail-closed on this exact head; do not transfer older successes.

Independent APPROVE is still required. Copilot / CodeRabbit / Devin COMMENT is not APPROVE. Do not self-approve. Do not mix leftover-map coordinate ticks (ADR 0270 / v2.27.0) into this PR — that increment stacks onto feat/leftover-map-coordinates-v2240 so pair-row ξ (x, y) ζ (x, y) matches graphic-display ticks without adding columns.
