# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-26)

**Core value:** Admins can describe ranking criteria in natural language, the system interprets and ranks projects accordingly, and they can advance the top projects to the next round with one click — all with full override control.
**Current focus:** Phase 1 — AI Ranking Backend

## Current Position

Phase: 1 of 4 (AI Ranking Backend)
Plan: 3 of TBD in current phase
Status: In progress
Last activity: 2026-02-27 — Plan 03 complete: tRPC rankingRouter with 5 procedures registered in appRouter

Progress: [███░░░░░░░] ~30%

## Performance Metrics

**Velocity:**
- Total plans completed: 3
- Average duration: ~3 min
- Total execution time: ~10 min

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01-ai-ranking-backend | 3 | ~10 min | ~3 min |

**Recent Trend:**
- Last 5 plans: 01-01 (~3 min), 01-02 (~3 min), 01-03 (~4 min)

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- [Init]: RankingSnapshot model (new table) preferred over Round.metadataJson for audit history — confirm with client before writing migration
- [Init]: Per-category processing (STARTUP / BUSINESS_CONCEPT) — two parallel AI calls, not one combined call
- [Init]: Phase 4 is independent and can be parallelized with Phases 2-3
- [01-01]: Used separate relation names per FK pair (RoundRankingSnapshots / TriggeredRankingSnapshots) — Prisma requires unique relation names per FK, not per target model
- [01-01]: All EvaluationConfig ranking fields are optional/defaulted for backward compatibility with existing rounds
- [01-01]: Created migration SQL manually (20260227000000_add_ranking_snapshot) — local DB credentials unavailable; migration applies on next deploy
- [01-02]: fetchAndRankCategory exported (not private) so tRPC router can execute pre-parsed rules without re-parsing
- [01-02]: Projects with zero SUBMITTED evaluations excluded from ranking entirely (not ranked last)
- [01-02]: PrismaClient imported as real type (not import type) so transaction clients are compatible
- [01-03]: Typed arrays cast to Prisma.InputJsonValue via `unknown` (direct cast rejected by strict TS — no index signature)
- [01-03]: getSnapshot uses findUnique + manual TRPCError NOT_FOUND (findUniqueOrThrow gives INTERNAL_SERVER_ERROR)

### Pending Todos

None yet.

### Blockers/Concerns

- [Phase 1]: French/English variable naming for EmailTemplate bilingual fields needs client confirmation before Phase 3 schema migration
- [Phase 1]: Poste.io bulk-send rate limits need verification before Phase 3 load testing
- [Phase 3]: Tiptap Mention extension API in v3.x should be validated against Tiptap v3 docs before implementation
