Buyer next action

After make seed, leftover post–criterion pairs sit above the member list with leftover-map lengths ‖ξ‖ and ‖ζ‖ next to leftover-map distance d. Click the pair to open that post. The length badges are omitted when the pair has no complete-case leftover map (fallback rows do not invent magnitude). Origin coordinates persist length 0 because that is the measured leftover-map magnitude. Never invent leftover score or theta.

A close leftover-map pair is not the same fact as leftover-map magnitude. Length names Gabriel vector length independently of Euclidean distance: origin close (d=0, ‖ξ‖=‖ζ‖=0) is not aligned leftover-map displacement (d=0 with positive length).

Scope (this PR only)

  • ADR 0181 leftover-map length
  • migration 0181 nullable leftover_map_person_length and leftover_map_item_length on leftover pair rows
  • persist/fetch/seed leftover-map lengths when a complete-case leftover map exists
  • frontend ‖ξ‖ / ‖ζ‖ badges + named next action; i18n en/ko/zh/ja/vi
  • release 2.12.25

Persist leftover-map lengths ‖ξ‖ and ‖ζ‖ on leftover post–criterion
pairs so leftover-map magnitude is not read as leftover-map distance.
Fallback pairs omit length rather than inventing one.

🔴 Leftover-length test reads attributes that never exist

The new assertions read closest.leftover_map_person_length and leftover_map_item_length (plus the farthest pair), but LeftoverPair in leftover_pairs.py defines no such fields and this PR leaves that file untouched. Every run raises AttributeError and the test fails. The backend never computes or persists these lengths.

Prompt for agents
The added assertions in tests/test_period_report.py reference LeftoverPair.leftover_map_person_length and LeftoverPair.leftover_map_item_length, but these fields were never added to the LeftoverPair dataclass in lineageweave/leftover_pairs.py, and no code computes them. The PR (per ADR 0181 and its own description) is supposed to persist/compute the Euclidean lengths of the Gabriel person coordinate (norm of person_coord) and item coordinate (norm of item_coord) that produced the leftover-map distance, omitting them (None) when there is no complete-case leftover map. Implement this: add nullable length fields to LeftoverPair, compute them in leftover_pairs_from_residual (person_coord/item_coord are already available around leftover_pairs.py:90-91 where distance is computed; the fallback branch at leftover_pairs.py:99-114 has no coordinates so lengths should be None), thread them through _candidate_row/_pair_from_candidate, and update the report serialization/API and frontend wiring so the new columns and badges are actually populated. Otherwise the test suite fails with AttributeError.

🔍 Frontend formatter not wired into UI

formatLeftoverMapLength and its person/item variants are exported and unit-tested, but no component imports them. The badges and i18n the PR describes are absent, so the formatter renders nothing to a buyer.

Resolves the migrate.sh allowlist conflict between this PR's own new
migrations (0179-0182: inner product, cosine, length, reconstruction)
and the 0173 fix that landed further up the leftover-map stack (PRs
#530-#533, already merged) -- union of both sides' migration numbers.

CHANGELOG.md merged cleanly this time (no reordering needed).

Verified: 33 passed in tests/test_schema.py + tests/test_migration_replay.py,
6 passed in tests/test_leftover_pairs.py, against a fresh Postgres 16
instance with the full migration chain applied.
