# API Router Reference: Architecture Redesign

## Overview

This document provides a complete reference of all tRPC router changes for the MOPC architecture redesign. Every procedure — new, modified, preserved, and removed — is documented with full Zod schemas.

**Key Changes Summary:**
- **Renamed Routers**: `pipeline` → `competition`, Stage CRUD split between `competition` and `round` routers
- **New Routers**: `jury-group`, `winner-confirmation`, `submission-window`, `mentor-workspace`
- **Enhanced Routers**: `assignment`, `evaluation`, `file`, `applicant`, `award`, `live-control`, `mentor`
- **Eliminated**: `stageTransition` procedures (replaced by linear advancement rules)
- **Procedure Count**: ~180 existing procedures, ~60 new, ~30 modified, ~20 removed

---

## Router Rename Map

| Current Router | Redesigned Router | Reason |
|----------------|-------------------|--------|
| `pipeline.ts` | `competition.ts` | Domain-specific naming |
| `stage.ts` | Split: `competition.ts` (CRUD) + `round.ts` (runtime) | Clearer separation of concerns |
| `assignment.ts` | `assignment.ts` (enhanced) | Add jury group awareness |
| `specialAward.ts` | `award.ts` | Enhanced for two-mode awards |
| `mentor.ts` | `mentor.ts` + `mentor-workspace.ts` | Separate workspace features |
| *(new)* | `jury-group.ts` | Explicit jury management |
| *(new)* | `winner-confirmation.ts` | Multi-party winner approval |
| *(new)* | `submission-window.ts` | Multi-round document requirements |

---

## 1. Competition Router (replaces Pipeline)

**File:** `src/server/routers/competition.ts` (renamed from `pipeline.ts`)

### Removed Procedures

All Track-related procedures are eliminated (Track model is removed):
- ~~`pipeline.createStructure`~~ — Replaced by `competition.createStructure` (no tracks)
- ~~`pipeline.getDraft`~~ — Replaced by `competition.getDraft` (returns rounds, not tracks)
- ~~`pipeline.updateStructure`~~ — Replaced by `competition.updateStructure` (rounds only)
- ~~`pipeline.getApplicantView`~~ — Moved to `applicant.getCompetitionView`

### Modified Procedures

#### `create` → `competition.create`
**Changes:** Rename references, simplified settings (no track concept)

```typescript
// Input schema
z.object({
  programId: z.string(),
  name: z.string().min(1).max(255),
  slug: z.string().min(1).max(100).regex(/^[a-z0-9-]+$/),

  // NEW: Competition-wide settings (typed, not generic JSON)
  categoryMode: z.enum(['SHARED', 'SPLIT']).default('SHARED'),
  startupFinalistCount: z.number().int().min(1).default(3),
  conceptFinalistCount: z.number().int().min(1).default(3),

  // Notification preferences
  notifyOnRoundAdvance: z.boolean().default(true),
  notifyOnDeadlineApproach: z.boolean().default(true),
  deadlineReminderDays: z.array(z.number().int()).default([7, 3, 1]),
})

// Output: Competition
```

#### `update` → `competition.update`
**Changes:** Add typed settings fields

```typescript
// Input schema
z.object({
  id: z.string(),
  name: z.string().min(1).max(255).optional(),
  slug: z.string().regex(/^[a-z0-9-]+$/).optional(),
  status: z.enum(['DRAFT', 'ACTIVE', 'CLOSED', 'ARCHIVED']).optional(),

  // NEW: Typed settings
  categoryMode: z.enum(['SHARED', 'SPLIT']).optional(),
  startupFinalistCount: z.number().int().min(1).optional(),
  conceptFinalistCount: z.number().int().min(1).optional(),
  notifyOnRoundAdvance: z.boolean().optional(),
  notifyOnDeadlineApproach: z.boolean().optional(),
  deadlineReminderDays: z.array(z.number().int()).optional(),
})

// Output: Competition
```

#### `get` → `competition.get`
**Changes:** Returns rounds array (flat), not tracks

```typescript
// Input schema
z.object({ id: z.string() })

// Output
{
  ...competition,
  program: { id, name },
  rounds: Array<{
    id, name, slug, roundType, status, sortOrder,
    windowOpenAt, windowCloseAt,
    juryGroup: { id, name } | null,
    submissionWindow: { id, name } | null,
    _count: { projectRoundStates, cohorts }
  }>,
  juryGroups: Array<{ id, name, _count: { members } }>,
  submissionWindows: Array<{ id, name, roundNumber }>,
  specialAwards: Array<{ id, name, status }>,
}
```

#### `list` → `competition.list`
**Changes:** Returns competition counts (no tracks)

```typescript
// Input schema
z.object({ programId: z.string() })

// Output
Array<{
  ...competition,
  _count: { rounds, juryGroups, submissionWindows, specialAwards }
}>
```

#### `publish` → `competition.publish`
**Changes:** Validates rounds instead of tracks

```typescript
// Input schema
z.object({ id: z.string() })

// Validation: Must have at least one round, all rounds must have configs
// Output: Competition with status = ACTIVE
```

### New Procedures

#### `createStructure`
**Purpose:** Atomically create Competition + Rounds + Jury Groups + Submission Windows

```typescript
// Input schema
z.object({
  programId: z.string().min(1),
  name: z.string().min(1).max(255),
  slug: z.string().min(1).max(100).regex(/^[a-z0-9-]+$/),

  // Competition-wide settings
  categoryMode: z.enum(['SHARED', 'SPLIT']).default('SHARED'),
  startupFinalistCount: z.number().int().default(3),
  conceptFinalistCount: z.number().int().default(3),

  // Rounds (linear array, no tracks)
  rounds: z.array(z.object({
    name: z.string().min(1).max(255),
    slug: z.string().min(1).max(100).regex(/^[a-z0-9-]+$/),
    roundType: z.enum([
      'INTAKE', 'FILTERING', 'EVALUATION',
      'SUBMISSION', 'MENTORING', 'LIVE_FINAL', 'CONFIRMATION'
    ]),
    sortOrder: z.number().int().min(0),
    configJson: z.record(z.unknown()).optional(),
    windowOpenAt: z.date().optional(),
    windowCloseAt: z.date().optional(),

    // Links to other entities
    juryGroupSlug: z.string().optional(),  // Will link to JuryGroup after creation
    submissionWindowSlug: z.string().optional(),
  })),

  // Jury groups
  juryGroups: z.array(z.object({
    name: z.string(),
    slug: z.string(),
    description: z.string().optional(),
    sortOrder: z.number().int(),
    defaultMaxAssignments: z.number().int().default(20),
    defaultCapMode: z.enum(['HARD', 'SOFT', 'NONE']).default('SOFT'),
    softCapBuffer: z.number().int().default(2),
    categoryQuotasEnabled: z.boolean().default(false),
    defaultCategoryQuotas: z.record(z.object({
      min: z.number().int(),
      max: z.number().int(),
    })).optional(),
  })),

  // Submission windows
  submissionWindows: z.array(z.object({
    name: z.string(),
    slug: z.string(),
    roundNumber: z.number().int(),
    sortOrder: z.number().int(),
    windowOpenAt: z.date().optional(),
    windowCloseAt: z.date().optional(),
    deadlinePolicy: z.enum(['HARD', 'FLAG', 'GRACE']).default('FLAG'),
    graceHours: z.number().int().optional(),
    lockOnClose: z.boolean().default(true),

    fileRequirements: z.array(z.object({
      name: z.string(),
      description: z.string().optional(),
      acceptedMimeTypes: z.array(z.string()),
      maxSizeMB: z.number().int().optional(),
      isRequired: z.boolean().default(true),
      sortOrder: z.number().int(),
    })),
  })),

  // Advancement rules (auto-generated linear flow by default)
  autoAdvancement: z.boolean().default(true),
})

// Output
{
  competition: Competition,
  rounds: Array<Round>,
  juryGroups: Array<JuryGroup>,
  submissionWindows: Array<SubmissionWindow>,
}
```

#### `updateStructure`
**Purpose:** Diff-based update (create/update/delete rounds, jury groups, windows)

```typescript
// Input schema
z.object({
  id: z.string(),
  name: z.string().optional(),
  slug: z.string().optional(),
  status: z.enum(['DRAFT', 'ACTIVE', 'CLOSED', 'ARCHIVED']).optional(),

  // Same nested arrays as createStructure, but with optional `id` fields
  rounds: z.array(z.object({
    id: z.string().optional(),  // Present = update, absent = create
    name: z.string(),
    // ... all other round fields
  })),

  juryGroups: z.array(z.object({
    id: z.string().optional(),
    name: z.string(),
    // ... all other jury group fields
  })),

  submissionWindows: z.array(z.object({
    id: z.string().optional(),
    name: z.string(),
    // ... all other submission window fields
  })),
})

// Logic:
// - Rounds/groups/windows with ID → update
// - Rounds/groups/windows without ID → create
// - Existing IDs not in input → delete (with safety checks: no active ProjectRoundStates)
```

#### `getDraft`
**Purpose:** Get full structure for wizard editing

```typescript
// Input schema
z.object({ id: z.string() })

// Output
{
  ...competition,

    submissionWindow: SubmissionWindow | null,
    visibleSubmissionWindows: Array<RoundSubmissionVisibility>,
    advancementRules: Array<AdvancementRule>,
    _count: { projectRoundStates },
  }>,
  juryGroups: Array<{
    ...juryGroup,
    members: Array<JuryGroupMember>,
    _count: { rounds, assignments },
  }>,
  submissionWindows: Array<{
    ...submissionWindow,
    fileRequirements: Array<SubmissionFileRequirement>,
    rounds: Array<{ id, name }>,
  }>,
  specialAwards: Array<{
    ...award,
    juryGroup: { id, name } | null,
    evaluationRound: { id, name } | null,
  }>,
}
```

#### `simulate`
**Purpose:** Dry-run project routing through competition

```typescript

  competitionId: string,
  competitionName: string,
  projectCount: number,
  simulations: Array<{
    projectId: string,
    projectTitle: string,
    currentStatus: ProjectStatus,
    targetRoundId: string | null,
    targetRoundName: string,
  }>,
}
```

### Preserved Procedures (renamed only)

- `delete` → `competition.delete` (archive)

```typescript
// Input schema
z.object({ winnerProposalId: z.string() })

**Purpose:** Admin unlocks results (rare, exceptional circumstances)

```typescript
// Input schema
z.object({

## 6. Assignment Router (enhanced)

**File:** `src/server/routers/assignment.ts`

### Modified Procedures

#### `create` → Enhanced with jury group awareness
**Changes:** Add `juryGroupId` parameter, enforce per-juror caps from JuryGroupMember

```typescript
// Input schema
z.object({
  userId: z.string(),
  projectId: z.string(),
  roundId: z.string(),  // RENAMED from stageId
  juryGroupId: z.string().optional(),  // NEW: Link to jury group
  isRequired: z.boolean().default(true),
  forceOverride: z.boolean().default(false),
})

// Validation:
// - Checks JuryGroupMember.maxAssignmentsOverride if set
// - Falls back to JuryGroup.defaultMaxAssignments
// - Falls back to User.maxAssignments
// - Enforces CapMode (HARD vs SOFT)

// Output: Assignment (with juryGroupId)
```

#### `bulkCreate` → Enhanced with capacity checking
**Changes:** Respect juryGroupId, apply category quotas

```typescript
// Input schema
z.object({
  roundId: z.string(),  // RENAMED from stageId
  juryGroupId: z.string().optional(),  // NEW
  assignments: z.array(z.object({
    userId: z.string(),
    projectId: z.string(),
  })),
})

// Logic:
// - For each juror, checks current count vs cap
// - If CapMode = HARD → rejects over-cap assignments
// - If CapMode = SOFT → allows up to softCapBuffer extra
// - Applies category quotas if categoryQuotasEnabled
// - Skips assignments that would violate quotas

// Output
{
  created: number,
  requested: number,
  skipped: number,
  skippedDueToCapacity: number,
  skippedDueToCategoryQuota: number,
}
```

#### `getSuggestions` → Enhanced with category quotas
**Changes:** Add quota scoring, penalty for over-quota categories

```typescript
// Input schema
z.object({
  roundId: z.string(),  // RENAMED from stageId
  juryGroupId: z.string().optional(),  // NEW
})

// Algorithm enhancements:
// - Fetches JuryGroup.defaultCategoryQuotas
// - Tracks per-juror category distribution
// - Penalizes assignments to over-quota categories (-25 score)
// - Bonuses assignments to under-quota categories (+10 score)

// Output: Array of suggestions with quota awareness
```

### New Procedures

#### `getJuryGroupStats`
**Purpose:** Per-group assignment coverage stats

```typescript
// Input schema
z.object({
  juryGroupId: z.string(),
  roundId: z.string(),
})

// Output
{
  juryGroup: { id, name },
  round: { id, name },
  members: Array<{
    user: { id, name, email },
    currentAssignments: number,
    cap: number,
    capMode: CapMode,
    categoryDistribution: Record<string, number>,  // Category → count
    quotaStatus: Record<string, { current, min, max, status }>,
  }>,
  totalAssignments: number,
  averageLoad: number,
  minLoad: number,
  maxLoad: number,
}
```

### Modified Procedures

#### All procedures: Rename `stageId` → `roundId` in inputs/outputs

#### `get`, `start`, `autosave`, `submit` — No functional changes, just renames

### New Procedures

#### `getCrossRoundDocs`
**Purpose:** Jury sees documents from multiple submission windows

```typescript
// Input schema (protectedProcedure)
z.object({
  projectId: z.string(),
  roundId: z.string(),
})

// Logic:
// - Fetches RoundSubmissionVisibility records for roundId
// - Returns files from all visible submission windows

// Output
{
  round: { id, name },
  submissionWindows: Array<{
    window: { id, name, roundNumber },
    displayLabel: string,
    files: Array<ProjectFile>,
    requirements: Array<SubmissionFileRequirement>,
  }>,
}
```

---

## 8. File Router (enhanced)

**File:** `src/server/routers/file.ts`

**Changes:** Check RoundSubmissionVisibility for jury access

```typescript
// Input schema (no changes)
z.object({
  bucket: z.string(),
  objectKey: z.string(),
})

// Logic changes:
// - If user is jury, checks Assignment.roundId
// - Looks up RoundSubmissionVisibility for that round
// - Grants access if file.submissionWindowId is in visible windows

// Output: { url }
```

#### `getUploadUrl` → Enhanced for submission window association
**Changes:** Link file to submissionWindowId

```typescript
// Input schema
z.object({
  projectId: z.string(),
  fileName: z.string(),
  fileType: z.enum(['EXEC_SUMMARY', 'PRESENTATION', 'VIDEO', 'OTHER']),
  mimeType: z.string(),
  size: z.number().int().positive(),

  submissionWindowId: z.string().optional(),  // NEW: Which window is this for?
  requirementId: z.string().optional(),  // Links to SubmissionFileRequirement
})

// Creates ProjectFile with submissionWindowId
// Output: { uploadUrl, fileId }
```

### New Procedures

#### `promoteFromMentor`
**Purpose:** Promote a MentorFile to official ProjectFile

```typescript
// Input schema
z.object({
  mentorFileId: z.string(),
  submissionWindowId: z.string(),
  requirementId: z.string().optional(),
})

// Logic:
// - Copies object in MinIO to new key
// - Creates ProjectFile linked to submissionWindow
// - Sets MentorFile.isPromoted = true, promotedToFileId

// Output: ProjectFile
