Matt 331b67dae0 Round system redesign: Phases 1-7 complete
Full pipeline/track/stage architecture replacing the legacy round system.

Schema: 11 new models (Pipeline, Track, Stage, StageTransition,
ProjectStageState, RoutingRule, Cohort, CohortProject, LiveProgressCursor,
OverrideAction, AudienceVoter) + 8 new enums.

Backend: 9 new routers (pipeline, stage, routing, stageFiltering,
stageAssignment, cohort, live, decision, award) + 6 new services
(stage-engine, routing-engine, stage-filtering, stage-assignment,
stage-notifications, live-control).

Frontend: Pipeline wizard (17 components), jury stage pages (7),
applicant pipeline pages (3), public stage pages (2), admin pipeline
pages (5), shared stage components (3), SSE route, live hook.

Phase 6 refit: 23 routers/services migrated from roundId to stageId,
all frontend components refitted. Deleted round.ts (985 lines),
roundTemplate.ts, round-helpers.ts, round-settings.ts, round-type-settings.tsx,
10 legacy admin pages, 7 legacy jury pages, 3 legacy dialogs.

Phase 7 validation: 36 tests (10 unit + 8 integration files) all passing,
TypeScript 0 errors, Next.js build succeeds, 13 integrity checks,
legacy symbol sweep clean, auto-seed on first Docker startup.

# Phase 01 Migration and Cutover Plan
## Strategy
Perform architecture rebuild with reset/reseed as the official path.
## Steps
1. Finalize schema migration scripts.
2. Run local reset/reseed rehearsal.
3. Run staging reset/reseed rehearsal.
4. Execute integrity verification suite.
5. Lock schema contracts and produce baseline snapshot.
## Verification Script Requirements
- count checks for canonical entities
- FK integrity checks
- expected stage graph checks
- expected project intake state checks
## Example Verification Queries
```sql
-- orphan project stage states
SELECT COUNT(*)
FROM "ProjectStageState" pss
LEFT JOIN "Project" p ON p.id = pss."projectId"
LEFT JOIN "Stage" s ON s.id = pss."stageId"
LEFT JOIN "Track" t ON t.id = pss."trackId"
WHERE p.id IS NULL OR s.id IS NULL OR t.id IS NULL;
-- project intake state coverage
SELECT COUNT(DISTINCT p.id) AS projects_without_intake
FROM "Project" p
LEFT JOIN "ProjectStageState" pss
ON pss."projectId" = p.id
LEFT JOIN "Stage" s
ON s.id = pss."stageId"
WHERE s."stageType" = 'INTAKE'
AND pss.id IS NULL;
```
## Cutover Readiness Artifacts Produced in Phase 01
- schema migration files
- seed scripts
- integrity query scripts
- reset/reseed execution logs
