Run 5 API Proxy — Implementation Summary

Date: 2026-04-09 Repository: api-proxy Plan: run-5-api-proxy/project-plan.md Exit gate: plan/run-5-api-proxy/validate-exit.sh Phase doc: phase-5-api-proxy/verification.md

Status

All four tracker tasks completed. Exit criteria passed.

Aligned the @arda-cards/api-proxy TypeScript package with the Phase 1–3 API contracts:

Replaced RenderResult with CompositeRenderResult and GroupRenderResult types matching the operations module’s serialisation.
Updated ItemProxy.printLabels(), ItemProxy.printBreadcrumbs(), and KanbanProxy.printCards() to return Promise<CompositeRenderResult>.
Added a PrintOptions parameter object accepting debug, dryRun, and livePrint, mapped into the appropriate query string.
Added KanbanProxy.unmarkPrinted(eId) calling POST /kanban-card/{eId}/event/unmark.
Updated the proxy unit tests to cover the new shapes and parameters.

PrintOptions as an object rather than three positional booleans, to keep call sites self-documenting and future-proof against new diagnostic flags.
unmarkPrinted typed against KanbanCardPrintStateChange, matching the operations endpoint return type, so consumers can read the resulting status without re-fetching the card.
No deprecation alias for RenderResult. The package was at 0.1.x and is consumed only by arda-frontend-app; a clean break was simpler than a migration window.

npm run build — green.
npm test — green; coverage maintained at 100% line and branch.
Integration with arda-frontend-app happens at the BFF layer; verified by the frontend’s own test suite.
