Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change computes and persists leftover report pairs across the database, API, and UI. At the current head, partially answered periods may produce incorrect pairs, and missing report-scoped foreign-key constraints may permit invalid cross-report data; these correctness and data-integrity issues should be fixed or explicitly accepted before merge.

Leftover pairs now join source_post visibility and use the same ABAC gate as report members. Hidden posts stay off the leftover list. The pair buttons name the leftover criterion as the next action.

@cwl-noema-review Independently review exact head This increment hides leftover pairs the buyer cannot open (same ABAC as members) and names the leftover criterion as the next action. Do not treat this comment as approval. Do not merge without an independent exact-head APPROVE plus green required checks on this SHA. |

Exact live head is now This slice stays off #74 / #92. Independent exact-head APPROVE is still required. This comment is not an approval and does not wait on Checks. |

In `@CHANGELOG.d/0.71.2-leftover-pairs.md`:
- Around line 7-10: Remove the duplicated release-note wording in
CHANGELOG.d/0.71.2-leftover-pairs.md, consolidating the repeated display and
click behavior into one concise description while preserving the references to
period reports, leftover pairs, member-list placement, and opening the
associated post.
In `@lineageweave/period_report.py`:
- Around line 292-296: Update the factorization flow around filled and
_leftover_map_positions so missing response cells are not represented as zero
residuals; use mask-aware factorization, or explicitly exclude rows and columns
containing missing values before SVD while preserving the mapping needed for
closest/farthest pair selection. Add a regression test covering a partially
observed synthetic matrix.
In `@migrations/0001_initial_schema.sql`:
- Around line 330-337: Update the leftover-pair table definition in
migrations/0001_initial_schema.sql and migrations/0012_report_leftover_pair.sql
to add composite foreign keys from (grouping_kind, grouping_key, period_code,
rubric_version, post_id) to report_member_score and from (grouping_kind,
grouping_key, period_code, rubric_version, criterion_code) to
report_item_information(item_code). In 0012_report_leftover_pair.sql, use
conditional ALTER TABLE ... ADD CONSTRAINT logic so the constraints are applied
to databases where the table already exists.

Cycle check: local leftover aeda64b vs this head. Will diff leftover_pairs isolation next. |
Leftover Gabriel factorization lives in leftover_pairs.py so leftover tests do not import period_report or fast_mlsirm. Missing response cells stay out of the complete-case rectangle. Leftover pairs now reference report_member_score and report_item_information.

Bring leftover post–criterion pairs (#211) and fail-closed Rankings (#220) onto this branch without colliding with the protected ADR and migration numbers already used here. Renumber main's leftover-pair migration to 0026 and ADRs to 0028–0030. Keep analysis-run create (0017), related-node walks (0018), seed period report (0024), and role-responsibility agent type (0012). Rankings sit above Calendar; leftover pairs sit above report members.

Buyer impact

make seed, closest and farthest leftover pairs sit above the member list. Click a pair to open that post.Period reports keep the IRT main-effect θ and CAT ranks. This slice adds the Jeon leftover map (eq. 3): residual
R = Y − E[Y|θ,item]after the already-fitted GRM/GPCM, Gabriel biplot positions on the complete-case residual rectangle, then one closest and one farthest observed post–criterion pair per report. A leftover pair for a hidden post is omitted the same way a hidden member is.Scope

Does not invent a leftover-pair API infast-mlsirm.report_leftover_pair(migration 0012 / ADR 0017). Cascade withreport_period_score.
