# T01: Split 945-line public-client.ts into 10 domain API modules with shared client.ts and barrel index.ts, updating all 17 consumers

**Split 945-line public-client.ts into 10 domain API modules with shared client.ts and barrel index.ts, updating all 17 consumers**

## What Happened

Split the monolithic public-client.ts into focused domain modules: client.ts (shared infrastructure), search.ts, techniques.ts, creators.ts, topics.ts, stats.ts, reports.ts, admin-pipeline.ts, admin-techniques.ts, auth.ts, plus a barrel index.ts. Updated all 17 consumer files to import from the barrel. Deleted the original monolith.

## Verification

npm run build exits 0 with zero TS errors. No public-client references remain in source. Both index.ts and client.ts exist. 11 .ts files in api/ directory.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npm run build` | 0 | ✅ pass | 4000ms |
| 2 | `! rg 'public-client' frontend/src/ -g '*.ts' -g '*.tsx'` | 0 | ✅ pass | 50ms |
| 3 | `test -f frontend/src/api/index.ts && test -f frontend/src/api/client.ts` | 0 | ✅ pass | 10ms |
| 4 | `ls frontend/src/api/*.ts | wc -l` | 0 | ✅ pass | 10ms |


## Deviations

SubTopicPage.tsx was an additional consumer not listed in the plan — updated the same way.

## Known Issues

None.
