Product changelog

Appearance

May 29, 2026 — Backend ​

Release date: Friday, May 29, 2026

Summary ​

A short week with two focused improvements: building cumulus now keeps estimated loss (EML) percent in sync with current-year coverage lines, and building types expose a reference endpoint for allow-listed price table lines (without year-specific rates) to support risk-profile and UI pickers.

Shipped ​

  • Cumulus EML: BuildingCumulus.estimatedLossPercent is recomputed from qualifying current-year CoverageLine EML and premium basis; runs after cumulus updates and when coverage lines are created.
  • Building types — price table lines: GET /api/v1/building-types/:id/price-table-lines returns mapped BuildingPriceTableLine rows (code, name, category, rateUnit, sort order) for a type; yearly rate remains on GET /insurance-years/:year/price-table-lines.

Engineering (commit recap) ​

Backend — week of May 25 – May 31, 2026 ​

Window: 2026-05-22 < commit date < 2026-05-30 (git log --no-merges).

Summary ​

Two non-merge commits landed. Cumulus gained CumulusEmlService and a pure calculator that aggregate coverage-line inputs into estimatedLossPercent, wired into existing cumulus and coverage-line write paths. Building types gained a nested reference route, DTO, tests, OpenAPI, and docs cross-links; insurance-year price-table listing was adjusted to align with the type-scoped allow-list pattern.

Themes ​

  • Cumulus EML automation: New cumulus-eml.calculator and CumulusEmlService load current-year coverages for a cumulus, compute percent from EML vs premium basis, and persist on BuildingCumulus; CumulusService and CoverageLineService trigger recompute after relevant mutations; unit tests cover calculator and service behavior.
  • Building type price table lines (reference): GET /building-types/:id/price-table-lines with building.view; returns BuildingTypePriceTableLineMap ordering without yearly rate; documented in API_REFERENCE_DATA.md and INSURANCE_BOUNDARIES_AND_CODES.md; http/api.http and OpenAPI updated; shared helper building-type-price-table-lines used from insurance-year listing where appropriate.

Notable fixes or risks (if any) ​

  • EML staleness: Percent updates on cumulus PATCH and coverage-line create only; other coverage-line changes (update/expire) should be verified if clients expect immediate EML refresh in those flows.
  • Two-step price lookup: Type endpoint omits rate; UIs that need NOK for a year must still call GET /insurance-years/:year/price-table-lines (optionally filtered by buildingTypeId).
