# Service Layer Changes

## Overview

This document details ALL service layer modifications required for the MOPC architecture redesign. The service layer is the orchestration tier between tRPC routers (API layer) and Prisma models (data layer). Most services are renamed (Stage → Round) and enhanced with new functionality, while a few new services are introduced.

## 1. Stage Engine → Round Engine

### Current Architecture

The `stage-engine.ts` service is a state machine that manages project transitions between pipeline stages. Key components:

1. **Guard evaluation** — Validates `guardJson` conditions on `StageTransition` records before allowing transitions
2. **Transition lookup** — Loads `StageTransition` records to find valid paths from `fromStageId` to `toStageId`
3. **Track references** — All operations include `trackId` for track-level isolation
4. **PSS lifecycle** — Creates/updates `ProjectStageState` records with `enteredAt`, `exitedAt`, and state changes

**Current function signatures:**

```typescript
// stage-engine.ts (CURRENT)

interface GuardCondition {
  field: string
  operator: 'eq' | 'neq' | 'in' | 'contains' | 'gt' | 'lt' | 'exists'
  value: unknown
}

interface GuardConfig {
  conditions?: GuardCondition[]
  logic?: 'AND' | 'OR'
  requireAllEvaluationsComplete?: boolean
  requireMinScore?: number
}

export async function validateTransition(
  projectId: string,
  fromStageId: string,
  toStageId: string,
  prisma: PrismaClient | any
): Promise<TransitionValidationResult>

export async function executeTransition(
  projectId: string,
  trackId: string,        // ← trackId required
  fromStageId: string,
  toStageId: string,
  newState: ProjectStageStateValue,
  actorId: string,
  prisma: PrismaClient | any
): Promise<TransitionExecutionResult>

export async function executeBatchTransition(
  projectIds: string[],
  trackId: string,        // ← trackId required
  fromStageId: string,
  toStageId: string,
  newState: ProjectStageStateValue,
  actorId: string,
  prisma: PrismaClient | any
): Promise<BatchTransitionResult>
```

### New Architecture: Round Engine

The redesigned `round-engine.ts` simplifies the state machine:

1. **Linear ordering** — Rounds have a `sortOrder` field. No guard evaluation needed — advancement is rule-based (see `AdvancementRule`)
2. **No StageTransition** — Replaced by `AdvancementRule` which specifies WHERE projects advance to and WHEN
3. **No trackId** — Projects belong to rounds, not track+stage combinations
4. **Simplified validation** — Only checks: round existence, window constraints, and round status

**New function signatures:**

```typescript
// round-engine.ts (NEW)

export interface RoundTransitionValidation {
  valid: boolean
  errors: string[]
  warnings?: string[]  // Non-blocking issues (e.g., "window closing soon")
}

export interface RoundTransitionResult {
  success: boolean
  projectRoundState: {
    id: string
    projectId: string
    roundId: string
    state: ProjectRoundStateValue
    enteredAt: Date
  } | null
  errors?: string[]
}

export interface BatchRoundTransitionResult {
  succeeded: string[]
  failed: Array<{ projectId: string; errors: string[] }>
  warnings: Array<{ projectId: string; warnings: string[] }>
  total: number
  advancementRuleApplied?: string  // Which AdvancementRule triggered the move
}

/**
 * Validate if a project can transition to a target round.
 * Checks:
 * 1. Source PRS exists and is not already exited
 * 2. Destination round exists and is active (not ROUND_DRAFT or ROUND_ARCHIVED)
 * 3. Window constraints on the destination round
 * 4. Project meets advancement criteria (if advancing from current round)
 *
 * No guard evaluation — advancement rules are checked separately.
 */
export async function validateRoundTransition(
  projectId: string,
  fromRoundId: string,
  toRoundId: string,
  prisma: PrismaClient | any
): Promise<RoundTransitionValidation>

/**
 * Execute a round transition for a single project atomically.
 * Within a transaction:
 * 1. Sets exitedAt on the source PRS
 * 2. Creates or updates the destination PRS with the new state
 * 3. Logs the transition in DecisionAuditLog
 * 4. Logs the transition in AuditLog
 *
 * No trackId parameter — projects are identified by projectId + roundId only.
 */
export async function executeRoundTransition(
  projectId: string,
  fromRoundId: string,
  toRoundId: string,
  newState: ProjectRoundStateValue,
  actorId: string,
  metadata?: Record<string, unknown>,  // Optional metadata (e.g., advancement rule, score threshold)
  prisma: PrismaClient | any
): Promise<RoundTransitionResult>

/**
 * Execute transitions for multiple projects in batches of 50.
 * Each project is processed independently so a failure in one does not
 * block others.
 *
 * Returns aggregated results with succeeded/failed counts and detailed errors.
 */
export async function executeBatchRoundTransition(
  projectIds: string[],
  fromRoundId: string,
  toRoundId: string,
  newState: ProjectRoundStateValue,
  actorId: string,
  metadata?: Record<string, unknown>,
  prisma: PrismaClient | any
): Promise<BatchRoundTransitionResult>

/**
 * Determine which round projects should advance to based on AdvancementRule config.
 * Replaces the old guard-based transition lookup.
 *
 * Returns the target round ID and the rule that was applied.
 */
export async function resolveAdvancementTarget(
  currentRoundId: string,
  projectId: string,
  prisma: PrismaClient | any
): Promise<{
  targetRoundId: string | null
  rule: {
    id: string
    ruleType: AdvancementRuleType
    config: Record<string, unknown>
  } | null
  eligible: boolean
  reasoning: string
}>

/**
 * Apply an advancement rule to eligible projects in a round.
 * Used for auto-advancement scenarios (e.g., "All PASSED projects advance to next round").
 */
export async function applyAdvancementRule(
  ruleId: string,
  actorId: string,
  dryRun?: boolean,  // Preview mode
  prisma: PrismaClient | any
): Promise<{
  eligible: number
  advanced: number
  errors: Array<{ projectId: string; reason: string }>
}>
```

Alternative paths:

PENDING ──► COMPLETED (skipped round, auto-advanced)
```

### Migration Path

1. **Create `round-engine.ts`** with new signatures
2. **Update all imports** from `stage-engine` to `round-engine` in:
   - `src/server/routers/pipeline.ts` → `round.ts`
   - Admin UI components that trigger transitions
3. **Remove `validateTransition` calls** that check for `StageTransition` records
4. **Replace guard logic** with `AdvancementRule` checks (use `resolveAdvancementTarget` and `applyAdvancementRule`)
5. **Delete `stage-engine.ts`** after verification

**Code impact:** ~30 files (routers, services, UI components) reference `stage-engine`.

---

## 2. Stage Assignment → Round Assignment

### Current Architecture

The `stage-assignment.ts` service generates jury-to-project assignments for evaluation rounds. It uses a scoring algorithm with:

1. **Tag overlap score** (max 40 points) — Juror expertise tags vs. project tags
2. **Workload balance score** (max 25 points) — Favors jurors below their target workload
3. **Geo-diversity score** (±5 points) — Slight penalty for same-country matches
4. **COI filtering** — Skips juror-project pairs with declared conflicts
5. **Assignment coverage** — Ensures each project gets `requiredReviews` jurors

**Current function signatures:**

```typescript
// stage-assignment.ts (CURRENT)

export interface AssignmentConfig {
  requiredReviews: number                // Projects reviewed per juror
  minAssignmentsPerJuror: number
  maxAssignmentsPerJuror: number
  respectCOI: boolean
  geoBalancing: boolean
  expertiseMatching: boolean
}

export async function previewStageAssignment(
  stageId: string,
  config: Partial<AssignmentConfig>,
  prisma: PrismaClient | any
): Promise<PreviewResult>

export async function executeStageAssignment(
  stageId: string,
  assignments: AssignmentInput[],
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ jobId: string; created: number; errors: string[] }>

export async function getCoverageReport(
  stageId: string,
  prisma: PrismaClient | any
): Promise<CoverageReport>

export async function rebalance(
  stageId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<RebalanceSuggestion[]>
```

### New Architecture: Round Assignment

The redesigned `round-assignment.ts` enhances the algorithm with:

1. **JuryGroup awareness** — Assignments are scoped to a jury group, not just a round
2. **Per-juror caps** — `JuryGroupMember.maxAssignmentsOverride` and `JuryGroupMember.capModeOverride` (HARD, SOFT, NONE)
3. **Category ratio enforcement** — New scoring component (max 10 points) for matching juror's preferred category ratio
4. **Enhanced workload scoring** — Considers juror's `preferredStartupRatio` when calculating balance
5. **Jury group defaults** — `JuryGroup.defaultMaxAssignments`, `defaultCapMode`, `defaultCategoryQuotas`

**New scoring breakdown:**

| Component | Max Points | Description |
|-----------|-----------|-------------|
| Tag overlap | 40 | Expertise tag match (juror tags ∩ project tags) |
| Workload balance | 25 | Distance from target load (favors jurors below cap) |
| Category ratio alignment | 10 | **NEW** — How well assignment fits juror's preferred STARTUP:CONCEPT ratio |
| Geo-diversity | ±5 | Same country = -5, different country = +5 |
| **Total** | **80** | Sum determines assignment priority |

**New function signatures:**

```typescript
// round-assignment.ts (NEW)

export interface RoundAssignmentConfig {
  requiredReviewsPerProject: number      // How many jurors per project (default: 3)

  // Cap enforcement (can be overridden per-juror)
  defaultCapMode: CapMode                // HARD | SOFT | NONE
  defaultMaxAssignments: number          // Default cap (e.g., 20)
  softCapBuffer: number                  // Extra assignments for SOFT mode (default: 2)

  // Category quotas (per juror)
  enforceCategoryQuotas: boolean         // Whether to respect per-juror min/max per category
  defaultCategoryQuotas?: {
    STARTUP: { min: number; max: number }
    BUSINESS_CONCEPT: { min: number; max: number }
  }

  // Scoring weights
  tagOverlapWeight: number               // Default: 40
  workloadWeight: number                 // Default: 25
  categoryRatioWeight: number            // Default: 10 (NEW)
  geoWeight: number                      // Default: 5

  // Filters
  respectCOI: boolean                    // Default: true
  applyGeoBalancing: boolean             // Default: true
  applyExpertiseMatching: boolean        // Default: true
}

export interface JuryGroupAssignmentContext {
  juryGroupId: string
  roundId: string
  members: Array<{
    userId: string
    name: string
    email: string
    expertiseTags: string[]
    country?: string

    // Effective limits (group default OR member override)
    maxAssignments: number
    capMode: CapMode
    categoryQuotas?: {
      STARTUP: { min: number; max: number }
      BUSINESS_CONCEPT: { min: number; max: number }
    }

    // Preferences
    preferredStartupRatio?: number       // 0.0 to 1.0 (e.g., 0.6 = 60% startups)

    // Current load
    currentAssignments: number
    currentStartupCount: number
    currentConceptCount: number
  }>
}

/**

 */
export async function rebalanceAssignments(
  roundId: string,
  juryGroupId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<RebalanceSuggestion[]>
```

### Enhanced Algorithm Pseudocode

```typescript
// Enhanced assignment algorithm with jury group + category ratio awareness

for each project in round {
  const projectCategory = project.competitionCategory  // STARTUP or BUSINESS_CONCEPT

  // Load jury group members with effective limits
  const jurors = await loadJuryGroupMembers(juryGroupId)

  // Score each juror for this project
  const candidates = jurors
    .filter(juror => {
      // Existing filters
      if (hasConflictOfInterest(juror, project)) return false
      if (alreadyAssigned(juror, project)) return false

      // NEW: Check caps and quotas
      const { canAssign } = canAssignMore(juror, projectCategory, config)
      if (!canAssign) return false

      return true
    })
    .map(juror => {
      // Existing scoring
      const tagScore = calculateTagOverlapScore(juror.expertiseTags, project.tags)  // max 40
      const workloadScore = calculateWorkloadScore(
        juror.currentAssignments,
        juror.maxAssignments
      )  // max 25
      const geoScore = calculateGeoScore(juror.country, project.country)  // ±5

      // NEW: Category ratio score
      const ratioScore = calculateCategoryRatioScore(
        juror.currentStartupCount,
        juror.currentConceptCount,
        juror.preferredStartupRatio,
        projectCategory
      )  // max 10

      const totalScore = tagScore + workloadScore + ratioScore + geoScore

      return { juror, score: totalScore }
    })
    .sort((a, b) => b.score - a.score)  // Descending

  // Assign top N jurors to this project
  const needed = config.requiredReviewsPerProject
  const selected = candidates.slice(0, needed)

  for (const { juror } of selected) {
    await createAssignment(project.id, juror.userId, roundId, juryGroupId)

    // Update in-memory counts for next iteration
    juror.currentAssignments++
    if (projectCategory === 'STARTUP') {
      juror.currentStartupCount++
    } else {
      juror.currentConceptCount++
    }
  }
}
```

### Migration Path

1. **Create `round-assignment.ts`** with new signatures
2. **Update `Assignment` model references** to include `juryGroupId`
3. **Create `getEffectiveLimits` utility** to load per-juror settings
4. **Implement `canAssignMore` guard** for cap/quota checks
5. **Implement `calculateCategoryRatioScore`** scoring function
6. **Update `previewRoundAssignment`** to use jury group context
7. **Update all routers** that call assignment functions
8. **Test with varied jury group configurations** (HARD caps, SOFT caps, category quotas)

**Code impact:** ~15 files (routers, admin UI, jury onboarding)

---

## 3. Stage Filtering → Round Filtering

### Changes: Minimal (Rename Only)

The `stage-filtering.ts` service logic is preserved almost entirely. Only naming changes:

| Current | New |
|---------|-----|
| `stageId` | `roundId` |
| `ProjectStageState` | `ProjectRoundState` |
| Function names: `runStageFiltering` | `runRoundFiltering` |
| Function names: `getManualQueue` (param `stageId`) | `getManualQueue` (param `roundId`) |

**All filtering logic remains the same:**
- Deterministic rules (FIELD_BASED, DOCUMENT_CHECK)
- AI screening with confidence banding
- Duplicate submission detection
- Manual review queue
- Override resolution

**New function signatures (only naming changes):**

```typescript
// round-filtering.ts (NEW — minimal changes from stage-filtering.ts)

export async function runRoundFiltering(
  roundId: string,        // ← renamed from stageId
  actorId: string,
  prisma: PrismaClient | any
): Promise<RoundFilteringResult>  // ← renamed type

export async function resolveManualDecision(
  filteringResultId: string,
  outcome: 'PASSED' | 'FILTERED_OUT',
  reason: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<void>

export async function getManualQueue(
  roundId: string,        // ← renamed from stageId
  prisma: PrismaClient | any
): Promise<ManualQueueItem[]>
```

### Migration Path

1. **Copy `stage-filtering.ts` to `round-filtering.ts`**
2. **Find/replace:** `stageId` → `roundId`, `Stage` → `Round`, `PSS` → `PRS`
3. **Update imports** in routers and UI
4. **Verify FilteringResult model** uses `roundId` foreign key
5. **Delete `stage-filtering.ts`**

**Code impact:** ~8 files (1 router, 7 UI components)

---

## 4. Stage Notifications → Round Notifications

### Current Architecture

The `stage-notifications.ts` service emits events from pipeline actions and creates in-app/email notifications. Key events:

- `stage.transitioned`
- `filtering.completed`
- `assignment.generated`
- `live.cursor_updated`
- `decision.overridden`

All events:
1. Create a `DecisionAuditLog` entry
2. Check `NotificationPolicy` for the event type
3. Resolve recipients (admins, jury, etc.)
4. Create `InAppNotification` records
5. Optionally send email

### New Architecture: Round Notifications

Enhancements:

1. **New event types** for new round types and features:
   - `submission_window.opened`
   - `submission_window.closing_soon` (deadline reminder)
   - `mentoring.workspace_activated`
   - `mentoring.file_uploaded`
   - `mentoring.file_promoted`
   - `confirmation.proposal_created`
   - `confirmation.approval_requested`
   - `confirmation.winners_frozen`

2. **Deadline reminder scheduling** — New utility `scheduleDeadlineReminders()` that creates future notifications for:
   - 7 days before window close
   - 3 days before window close
   - 1 day before window close
   - 1 hour before window close

3. **Template system integration** — Email templates for each event type (links to MinIO, jury dashboards, etc.)

**New function signatures:**

```typescript
// round-notifications.ts (NEW)

/**
 * Cancel scheduled reminders (if window is extended or closed early).
 */
export async function cancelDeadlineReminders(

```

### Recipient Resolution Enhancements

New recipient resolution logic for new event types:

```typescript
// Enhanced recipient resolution (internal helper)

async function resolveRecipients(
  eventType: string,
  details: Record<string, unknown>,
  prisma: PrismaClient | any
): Promise<NotificationTarget[]> {
  switch (eventType) {
    case 'submission_window.opened':
    case 'submission_window.closing_soon': {
      // Notify eligible project team members
      const projectIds = details.eligibleProjectIds as string[]
      const teamMembers = await prisma.teamMember.findMany({
        where: { projectId: { in: projectIds } },
        include: { user: { select: { id: true, name: true, email: true } } }
      })
      return teamMembers.map(tm => ({
        userId: tm.user.id,
        name: tm.user.name ?? 'Team Member',
        email: tm.user.email
      }))
    }

    case 'mentoring.workspace_activated':
    case 'mentoring.file_uploaded':
    case 'mentoring.file_promoted': {
      // Notify mentor + team members
      const projectId = details.projectId as string
      const mentorId = details.mentorId as string

      const [mentor, teamMembers] = await Promise.all([
        prisma.user.findUnique({
          where: { id: mentorId },
          select: { id: true, name: true, email: true }
        }),
        prisma.teamMember.findMany({
          where: { projectId },
          include: { user: { select: { id: true, name: true, email: true } } }
        })
      ])

      return [
        { userId: mentor.id, name: mentor.name ?? 'Mentor', email: mentor.email },
        ...teamMembers.map(tm => ({
          userId: tm.user.id,
          name: tm.user.name ?? 'Team Member',
          email: tm.user.email
        }))
      ]
    }

    case 'confirmation.proposal_created':
    case 'confirmation.approval_requested': {
      // Notify jury members who need to approve
      const proposalId = details.proposalId as string
      const approvals = await prisma.winnerApproval.findMany({
        where: { winnerProposalId: proposalId },
        include: { user: { select: { id: true, name: true, email: true } } }
      })
      return approvals.map(a => ({
        userId: a.user.id,
        name: a.user.name ?? 'Jury Member',
        email: a.user.email
      }))
    }

    case 'confirmation.winners_frozen': {
      // Notify all admins + jury group members
      const competitionId = details.competitionId as string
      const juryGroups = await prisma.juryGroup.findMany({
        where: { competitionId },
        include: {
          members: {
            include: { user: { select: { id: true, name: true, email: true } } }
          }
        }
      })

      const admins = await prisma.user.findMany({
        where: { role: { in: ['SUPER_ADMIN', 'PROGRAM_ADMIN'] } },
        select: { id: true, name: true, email: true }
      })

      const juryMembers = juryGroups.flatMap(jg =>
        jg.members.map(m => ({
          userId: m.user.id,
          name: m.user.name ?? 'Jury Member',
          email: m.user.email
        }))
      )

      return [
        ...admins.map(a => ({ userId: a.id, name: a.name ?? 'Admin', email: a.email })),
        ...juryMembers
      ]
    }

    // Existing cases preserved (stage.transitioned, filtering.completed, etc.)
    default:
      return resolveDefaultRecipients(eventType, details, prisma)
  }
}
```

### Migration Path

1. **Copy `stage-notifications.ts` to `round-notifications.ts`**
2. **Rename references:** `stageId` → `roundId`, `Stage` → `Round`
3. **Add new event producers** for submission windows, mentoring, confirmation
4. **Implement `scheduleDeadlineReminders`** (use Vercel Cron or BullMQ)
5. **Update recipient resolution** with new cases
6. **Create email templates** for new event types
7. **Delete `stage-notifications.ts`**

**Code impact:** ~20 files (routers, services that emit events)

---

## 5. Live Control — Enhanced

### Current Architecture

The `live-control.ts` service manages real-time control of live final events:

- Session management (start/pause/resume)
- Cursor navigation (setActiveProject, jumpToProject)
- Queue reordering
- Cohort window management (open/close voting windows)

### Enhancements

1. **Category-based cohorts** — Enhanced cohort management to handle per-category voting windows:
   - `openCohortWindowForCategory(cohortId, category, actorId)` — Open voting only for STARTUP or BUSINESS_CONCEPT projects
   - `closeCohortWindowForCategory(cohortId, category, actorId)` — Close voting for a category

2. **Stage manager enhancements** — New UI utilities:
   - `getCurrentCohortStatus(roundId)` — Returns active cohort, remaining projects, voting status per category
   - `getNextProject(roundId, currentProjectId)` — Smart navigation (skip to next un-voted project)

3. **Audience participation tracking** — Integration with `AudienceVoter` for real-time vote counts

**New function signatures:**

```typescript
// live-control.ts (ENHANCED)

// ─── Existing functions preserved ────────────────────────────────────
// startSession, setActiveProject, jumpToProject, reorderQueue, pauseResume
// openCohortWindow, closeCohortWindow

// ─── New: Category-specific cohort windows ───────────────────────────

/**
 * Open voting for a specific category within a cohort.
 * Useful for staggered voting (e.g., "Startups vote now, Concepts later").
 */
export async function openCohortWindowForCategory(
  cohortId: string,
  category: CompetitionCategory,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Close voting for a specific category within a cohort.
 */
export async function closeCohortWindowForCategory(
  cohortId: string,
  category: CompetitionCategory,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

// ─── New: Stage manager utilities ────────────────────────────────────

/**
 * Get the current status of live session (for stage manager UI).
 * Returns: active project, cohort status, vote counts, next project preview.
 */
export async function getCurrentCohortStatus(
  roundId: string,
  prisma: PrismaClient | any
): Promise<{
  sessionId: string | null
  isPaused: boolean
  activeProjectId: string | null
  activeProjectTitle: string | null
  activeCohort: {
    id: string
    name: string
    isOpen: boolean
    categoryWindows: Array<{
      category: CompetitionCategory
      isOpen: boolean
      voteCount: number
    }>
  } | null
  queueStatus: {
    totalProjects: number
    currentIndex: number
    remaining: number
  }
  nextProject: {
    id: string
    title: string
    category: CompetitionCategory
  } | null
}>

/**
 * Navigate to the next project in the queue.
 * Optionally skip projects that have already been voted on.
 */
export async function getNextProject(
  roundId: string,
  currentProjectId: string | null,
  skipVoted?: boolean,
  prisma: PrismaClient | any
): Promise<{
  projectId: string | null
  projectTitle: string | null
  orderIndex: number | null
}>

/**
 * Get real-time vote counts for the active project (jury + audience).
 */
export async function getActiveProjectVotes(
  roundId: string,
  projectId: string,
  prisma: PrismaClient | any
): Promise<{
  juryVotes: Array<{
    userId: string
    userName: string
    score: number | null
    votedAt: Date | null
  }>
  audienceVotes: {
    totalVotes: number
    averageScore: number
  }
  combined: {
    totalScore: number
    averageScore: number
  }
}>
```

### Migration Path

1. **Update `live-control.ts`** with new functions
2. **Add `Cohort.categoryWindowStatus` JSON field** (optional — stores per-category open/close state)
3. **Create `getCurrentCohortStatus` utility** for stage manager UI
4. **Implement `getNextProject` navigation** with skip logic
5. **Update stage manager UI** to use new utilities

**Code impact:** ~5 files (1 service, 1 router, 3 UI components)

---

## 6. NEW: Submission Round Manager

### Purpose

The `submission-round-manager.ts` service manages the lifecycle of multi-round submission windows. It handles:

1. **Window lifecycle** — Opening, closing, locking, extending submission windows
2. **File requirement validation** — Ensuring teams upload all required files
3. **Deadline enforcement** — HARD (reject), FLAG (accept but mark late), GRACE (accept during grace period)
4. **Window locking** — When a new window opens, previous windows lock for applicants (jury can still view)

**Complete function signatures:**

```typescript
// submission-round-manager.ts (NEW)

export interface SubmissionWindowStatus {
  id: string
  name: string
  roundNumber: number
  isOpen: boolean
  isLocked: boolean
  windowOpenAt: Date | null
  windowCloseAt: Date | null
  deadlinePolicy: DeadlinePolicy
  graceHours: number | null
  graceEndsAt: Date | null  // Calculated: windowCloseAt + graceHours
  requirements: Array<{
    id: string
    name: string
    description: string | null
    acceptedMimeTypes: string[]
    maxSizeMB: number | null
    isRequired: boolean
    sortOrder: number
  }>
  stats: {
    totalProjects: number
    completeSubmissions: number
    partialSubmissions: number
    lateSubmissions: number
  }
}

export interface SubmissionValidation {
  valid: boolean
  errors: string[]
  warnings: string[]
  missingRequirements: Array<{
    requirementId: string
    name: string
  }>
}

/**

 */
export async function openSubmissionWindow(
  submissionWindowId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Close a submission window. Sets windowCloseAt to now.
 * If deadlinePolicy is HARD or GRACE (with grace expired), further submissions are rejected.
 */
export async function closeSubmissionWindow(
  submissionWindowId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Extend a submission window deadline.
 * Updates windowCloseAt and recalculates grace period if applicable.
 */
export async function extendSubmissionWindow(
  submissionWindowId: string,
  newCloseAt: Date,
  reason: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Lock a submission window for applicants (admin override).
 * Locked windows are read-only for teams but visible to jury.
 */
export async function lockSubmissionWindow(
  submissionWindowId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Unlock a submission window (admin override).
 */
export async function unlockSubmissionWindow(
  submissionWindowId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Check if a project has submitted all required files for a window.
 * Returns validation result with missing requirements.
 */
export async function validateSubmission(
  projectId: string,
  submissionWindowId: string,
  prisma: PrismaClient | any
): Promise<SubmissionValidation>

/**
 * Enforce deadline policy when a file is uploaded.
 * Returns whether the upload should be accepted or rejected.
 */
export async function checkDeadlinePolicy(
  submissionWindowId: string,
  uploadedAt: Date,
  prisma: PrismaClient | any
): Promise<{
  accepted: boolean
  isLate: boolean
  reason?: string  // If rejected, why?
}>

/**
 * Get status of a submission window including requirements and stats.
 */
export async function getSubmissionWindowStatus(
  submissionWindowId: string,
  prisma: PrismaClient | any
): Promise<SubmissionWindowStatus>

/**
 * Get all submission windows for a competition, ordered by roundNumber.
 */
export async function listSubmissionWindows(
  competitionId: string,
  prisma: PrismaClient | any
): Promise<SubmissionWindowStatus[]>

/**
 * Lock all previous submission windows when a new window opens.
 * Called automatically by openSubmissionWindow.
 */
async function lockPreviousWindows(
  competitionId: string,
  currentRoundNumber: number,
  prisma: PrismaClient | any
): Promise<void>
```

### Deadline Policy Logic

```typescript
// Deadline enforcement logic

async function checkDeadlinePolicy(
  submissionWindowId: string,
  uploadedAt: Date,
  prisma: PrismaClient | any
): Promise<{ accepted: boolean; isLate: boolean; reason?: string }> {
  const window = await prisma.submissionWindow.findUnique({
    where: { id: submissionWindowId }
  })

  if (!window) {
    return { accepted: false, isLate: false, reason: 'Submission window not found' }
  }

  // Before window opens
  if (window.windowOpenAt && uploadedAt < window.windowOpenAt) {
    return { accepted: false, isLate: false, reason: 'Submission window has not opened yet' }
  }

  // Window still open
  if (!window.windowCloseAt || uploadedAt <= window.windowCloseAt) {
    return { accepted: true, isLate: false }
  }

  // After window closes
  switch (window.deadlinePolicy) {
    case 'HARD':
      return {
        accepted: false,
        isLate: true,
        reason: 'Submission deadline has passed (HARD policy)'
      }

    case 'FLAG':
      return {
        accepted: true,
        isLate: true  // Accepted but marked as late
      }

    case 'GRACE': {
      if (!window.graceHours) {
        return { accepted: false, isLate: true, reason: 'Grace period not configured' }
      }

      const graceEndsAt = new Date(window.windowCloseAt.getTime() + window.graceHours * 60 * 60 * 1000)

      if (uploadedAt <= graceEndsAt) {
        return { accepted: true, isLate: true }  // Within grace period
      } else {
        return {
          accepted: false,
          isLate: true,
          reason: `Grace period ended at ${graceEndsAt.toISOString()}`
        }
      }
    }

    default:
      return { accepted: false, isLate: true, reason: 'Unknown deadline policy' }
  }
}
```

### Integration Points

- **Called by:** `project.uploadFile` router (before accepting uploads)
- **Calls:** `round-notifications.onSubmissionWindowOpened`, `scheduleDeadlineReminders`
- **Emits events:** `submission_window.opened`, `submission_window.closed`, `submission_window.extended`

**Code impact:** New file + 2 router endpoints + 3 UI components

## 7. NEW: Mentor Workspace Service

### Purpose

The `mentor-workspace.ts` service manages the mentoring workspace where mentors and teams collaborate. It handles:

1. **File upload to workspace** — Mentors and teams upload working files (drafts, notes, feedback)
2. **Threaded comments** — Both parties can comment on files (with replies)
3. **File promotion** — Mentors can promote workspace files to official submissions
4. **Activity tracking** — Last viewed timestamps, unread counts

**Complete function signatures:**

```typescript

### File Promotion Logic

When a mentor promotes a workspace file to an official submission:

```typescript
async function promoteFileToSubmission(
  fileId: string,
  submissionWindowId: string,
  requirementId: string | null,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ projectFileId: string; errors?: string[] }> {
  const mentorFile = await prisma.mentorFile.findUnique({
    where: { id: fileId },
    include: { mentorAssignment: true }
  })

  if (!mentorFile) {
    return { projectFileId: '', errors: ['File not found'] }
  }

  if (mentorFile.isPromoted) {
    return { projectFileId: '', errors: ['File has already been promoted'] }
  }

  // Verify actor is the mentor
  if (actorId !== mentorFile.mentorAssignment.mentorId) {
    return { projectFileId: '', errors: ['Only the mentor can promote files'] }
  }

  const result = await prisma.$transaction(async (tx: any) => {
    // Create ProjectFile
    const projectFile = await tx.projectFile.create({
      data: {
        projectId: mentorFile.mentorAssignment.projectId,
        submissionWindowId,
        requirementId,
        fileType: 'SUBMISSION_DOCUMENT',
        fileName: mentorFile.fileName,
        mimeType: mentorFile.mimeType,
        size: mentorFile.size,
        bucket: mentorFile.bucket,
        objectKey: mentorFile.objectKey,
        isLate: false,  // Promotions are never late
        version: 1,
      }
    })

    // Update MentorFile
    await tx.mentorFile.update({
      where: { id: fileId },
      data: {
        isPromoted: true,
        promotedToFileId: projectFile.id,
        promotedAt: new Date(),
        promotedByUserId: actorId,
      }
    })

    // Audit log
    await tx.decisionAuditLog.create({
      data: {
        eventType: 'mentoring.file_promoted',
        entityType: 'MentorFile',

        actorId,
        detailsJson: {
          projectFileId: projectFile.id,
          projectId: mentorFile.mentorAssignment.projectId,
          submissionWindowId,
        }
      }
    })

    return projectFile
  })

  // Emit notification
  await onMentoringFilePromoted(
    fileId,
    result.id,
    mentorFile.mentorAssignment.projectId,
    actorId,
    prisma
  )

  return { projectFileId: result.id, errors: [] }
}
```

### Integration Points

- **Called by:** `mentor.uploadFile`, `mentor.promoteFile` routers
- **Calls:** `round-notifications.onMentoringFileUploaded`, `onMentoringFilePromoted`
- **Emits events:** `mentoring.workspace_activated`, `mentoring.file_uploaded`, `mentoring.file_promoted`

**Code impact:** New file + 5 router endpoints + 4 UI components (mentor dashboard, workspace viewer, file uploader, comment thread)

## 8. NEW: Winner Confirmation Service

### Purpose

The `winner-confirmation.ts` service orchestrates the multi-party winner agreement process for the CONFIRMATION round. It handles:

1. **Proposal generation** — Create `WinnerProposal` with ranked project IDs (from scores, admin selection, or AI recommendation)
2. **Approval processing** — Track jury member approvals/rejections
3. **Override logic** — Admin can override with FORCE_MAJORITY or ADMIN_DECISION
4. **Freeze mechanism** — Lock results once approved (or overridden)

**Complete function signatures:**

```typescript
// winner-confirmation.ts (NEW)

  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Freeze a proposal (lock results, make official).
 * Can only freeze if:
 * - All approvals received OR
 * - Override has been applied
 */
export async function freezeProposal(
  proposalId: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }>

/**
 * Unfreeze a proposal (admin undo).
 * Allows re-opening the approval process.
 */
export async function unfreezeProposal(

): Promise<ProposalStatus>

/**
 * List all proposals for a competition (both categories).
 */
export async function listProposals(
  competitionId: string,
  prisma: PrismaClient | any
): Promise<ProposalStatus[]>
```

### Approval Logic

```typescript
// Check approval status and determine if auto-freeze should happen

async function checkApprovalStatus(
  proposalId: string,
  prisma: PrismaClient | any
): Promise<{
  allApproved: boolean
  anyRejected: boolean
  pendingCount: number
  shouldAutoFreeze: boolean
}> {
  const proposal = await prisma.winnerProposal.findUnique({
    where: { id: proposalId },
    include: {
      approvals: {
        where: { role: 'JURY_MEMBER' }
      }
    }
  })

  if (!proposal) {
    return {
      allApproved: false,
      anyRejected: false,
      pendingCount: 0,
      shouldAutoFreeze: false
    }
  }

  const approvals = proposal.approvals
  const approved = approvals.filter(a => a.approved === true)
  const rejected = approvals.filter(a => a.approved === false)
  const pending = approvals.filter(a => a.approved === null)

  const allApproved = pending.length === 0 && rejected.length === 0 && approved.length === approvals.length
  const anyRejected = rejected.length > 0

  // Auto-freeze if all approved and config allows
  const roundConfig = await prisma.round.findUnique({
    where: { id: proposal.sourceRoundId },
    select: { configJson: true }
  })

  const config = (roundConfig?.configJson as Record<string, unknown>) ?? {}
  const autoFreezeOnApproval = (config.autoFreezeOnApproval as boolean) ?? true

  const shouldAutoFreeze = allApproved && autoFreezeOnApproval

  return {
    allApproved,
    anyRejected,
    pendingCount: pending.length,
    shouldAutoFreeze
  }
}
```

### Override Logic

```typescript
// Apply admin override to a proposal

async function overrideProposal(
  proposalId: string,
  overrideMode: 'FORCE_MAJORITY' | 'ADMIN_DECISION',
  overrideReason: string,
  actorId: string,
  prisma: PrismaClient | any
): Promise<{ success: boolean; errors?: string[] }> {
  const proposal = await prisma.winnerProposal.findUnique({
    where: { id: proposalId },
    include: { approvals: true }
  })

  if (!proposal) {
    return { success: false, errors: ['Proposal not found'] }
  }

  if (proposal.status === 'FROZEN') {
    return { success: false, errors: ['Proposal is already frozen'] }
  }

  await prisma.$transaction(async (tx: any) => {
    // Update proposal
    await tx.winnerProposal.update({
      where: { id: proposalId },
      data: {
        status: 'OVERRIDDEN',
        overrideUsed: true,
        overrideMode,
        overrideReason,
        overrideById: actorId,
      }
    })

    // Create override action
    await tx.overrideAction.create({
      data: {
        entityType: 'WinnerProposal',
        entityId: proposalId,
        previousValue: { status: proposal.status },
        newValueJson: { status: 'OVERRIDDEN', overrideMode },
        reasonCode: overrideMode,
        reasonText: overrideReason,
        actorId,
      }
    })

    // Audit log
    await tx.decisionAuditLog.create({
      data: {
        eventType: 'confirmation.proposal_overridden',
        entityType: 'WinnerProposal',
        entityId: proposalId,
        actorId,
        detailsJson: {
          overrideMode,
          overrideReason,
          competitionId: proposal.competitionId,
          category: proposal.category,
        }
      }
    })
  })

  return { success: true }
}
```

### Integration Points

- **Called by:** `confirmation.generateProposal`, `confirmation.submitApproval`, `confirmation.override`, `confirmation.freeze` routers
- **Calls:** `round-notifications.onWinnerProposalCreated`, `onWinnerApprovalRequested`, `onWinnersFrozen`
- **Emits events:** `confirmation.proposal_created`, `confirmation.approval_requested`, `confirmation.winners_frozen`

**Code impact:** New file + 6 router endpoints + 5 UI components (proposal creator, approval dashboard, override dialog, results viewer, freeze button)

## 9. AI Services Changes

### 9.1 AI Assignment — Enhanced with Jury Groups

**Changes:**

1. Add `juryGroupId` context to assignment prompts
2. Include per-juror cap/quota info in anonymized data
3. Enhanced reasoning to explain category ratio matches

**Modified function signature:**

```typescript
// ai-assignment.ts (ENHANCED)

export async function generateAIAssignments(
  roundId: string,
  juryGroupId: string,        // ← NEW parameter
  config: Partial<AssignmentConfig>,
  userId?: string,
  onProgress?: AssignmentProgressCallback,
  prisma?: PrismaClient | any
): Promise<AIAssignmentResult>

// Internal: Enhanced anonymization to include jury group context
interface AnonymizedJuror {
  id: string  // Anonymized ID
  expertiseTags: string[]
  currentLoad: number
  maxAssignments: number
  capMode: 'HARD' | 'SOFT' | 'NONE'  // ← NEW
  categoryQuotas?: {                 // ← NEW
    STARTUP: { min: number; max: number }
    BUSINESS_CONCEPT: { min: number; max: number }
  }
  preferredStartupRatio?: number     // ← NEW
}
```

**Migration:** Update 1 function, add juryGroupId to all calls.

### 9.2 AI Filtering — Rename Only

**Changes:** Rename `stageId` → `roundId` in all function signatures. No logic changes.

**Migration:** Find/replace in file.

### 9.3 AI Evaluation Summary — Minimal

**Changes:** Rename `stageId` → `roundId`. Logic preserved.

**Migration:** Find/replace in file.

### 9.4 AI Tagging — No Changes

**Preserved as-is.** Used for auto-tagging projects based on descriptions.

### 9.5 AI Award Eligibility — Enhanced

**Changes:**

1. Support new `AwardEligibilityMode` enum values: `STAY_IN_MAIN`, `SEPARATE_POOL`
2. Enhanced prompt to distinguish between modes
3. For `STAY_IN_MAIN`: AI flags projects as award-eligible without removing from main competition
4. For `SEPARATE_POOL`: AI recommends pulling projects out of main flow

**Modified function signature:**

```typescript
// ai-award-eligibility.ts (ENHANCED)

export async function evaluateAwardEligibility(
  awardId: string,
  projectIds: string[],
  eligibilityMode: AwardEligibilityMode,  // ← NEW parameter
  userId?: string,
  prisma?: PrismaClient | any
): Promise<AIAwardEligibilityResult>

// Updated result type
export interface AIAwardEligibilityResult {
  success: boolean
  eligibleProjects: Array<{
    projectId: string
    confidenceScore: number
    reasoning: string
    recommendPullFromMain?: boolean  // ← NEW (for SEPARATE_POOL mode)
  }>
  error?: string
  tokensUsed?: number
}
```

**Migration:** Add `eligibilityMode` parameter to all calls.

### 9.6 NEW: AI Mentoring Insights

**Purpose:** Generate AI-powered insights for mentors based on project data and progress.

**Complete function signatures:**

```typescript
// ai-mentoring-insights.ts (NEW)

export interface MentoringInsight {
  insightType: 'STRENGTH' | 'WEAKNESS' | 'RECOMMENDATION' | 'MILESTONE'
  title: string
  description: string
  priority: 'HIGH' | 'MEDIUM' | 'LOW'
  actionable: boolean
  suggestedActions?: string[]
}

export interface AIMentoringInsightsResult {
  success: boolean
  insights: MentoringInsight[]
  overallAssessment: {
    readinessScore: number  // 0-10
    strengths: string[]
    areasForImprovement: string[]
    suggestedFocus: string
  }
  error?: string
  tokensUsed?: number
}

/**
 * Generate mentoring insights for a project based on:
 * - Project description and submission files
 * - Evaluation scores and feedback (if available)
 * - Mentor notes and messages
 * - Milestone completion status
 *
 * Returns actionable recommendations for the mentor to guide the team.
 */
export async function generateMentoringInsights(
  projectId: string,
  mentorAssignmentId: string,
  userId?: string,
  prisma?: PrismaClient | any
): Promise<AIMentoringInsightsResult>
```

**Integration:** Called by `mentor.getInsights` router.

**Code impact:** New file + 1 router endpoint + 1 UI component (insights panel)

4. **round-engine.ts** — Create new, simplified state machine
5. **round-filtering.ts** — Rename from stage-filtering, use ai-filtering
6. **round-assignment.ts** — Enhance from stage-assignment, use ai-assignment

### Phase 3: New Services (Depend on Phase 1-2)
7. **submission-round-manager.ts** — Create new
8. **mentor-workspace.ts** — Create new
9. **winner-confirmation.ts** — Create new

## Summary

| Category | Count | Action |
|----------|-------|--------|
| **Renamed services** | 4 | stage-* → round-* |
| **Enhanced services** | 4 | round-assignment, live-control, ai-assignment, ai-award-eligibility |
| **New services** | 4 | submission-round-manager, mentor-workspace, winner-confirmation, ai-mentoring-insights |
| **Preserved services** | 7 | anonymization, mentor-matching, in-app-notification, email-digest, evaluation-reminders, webhook-dispatcher, award-eligibility-job |
| **Deprecated services** | 1 | smart-assignment |
| **Total service files** | 19 | (was 20, now 19) |

**Lines of code impact:**
- **New code:** ~2,500 lines (4 new services)
- **Modified code:** ~1,200 lines (enhancements)
- **Renamed code:** ~1,800 lines (copy-paste with renames)
- **Deleted code:** ~400 lines (deprecated service)
- **Net change:** +3,300 lines

**Estimated development time:**
- Phase 1-2: 3 days (foundation + core)
- Phase 3: 5 days (new services)
- Phase 4: 3 days (enhancements)
- Phase 5: 1 day (cleanup)
- **Total:** 12 days (2.4 weeks)

**Risk areas:**
1. **Round engine simplification** — Ensure advancement rules fully replace guard logic
2. **Jury group assignment scoring** — Test category ratio calculations with edge cases
3. **Deadline policy enforcement** — Verify HARD/FLAG/GRACE logic in all scenarios
4. **Winner confirmation approval flow** — Test multi-jury approval + override paths
5. **Notification event cascades** — Ensure no infinite loops or missing recipients
