# bf-1pc: SPA R2→B2 Path Migration

## Task
Fix SPA TypeScript source: replace `/r2/` data path prefix with `/b2/` for B2 migration.

## Status: Already Complete

This work was already completed in commits:
- `76369b5`: "fix(spa): replace /r2/ data path prefix with /b2/"
- `724f516`: "fix(spa): replace r2.aicodebattle.com with b2.aicodebattle.com"

## Acceptance Criteria Verified

1. ✓ `grep -r "/r2/" src/` returns no hits (exit code 1 = no matches)
2. ✓ `npm run build` succeeds (completed in 3.38s)
3. ✓ `grep -r "r2.aicodebattle" dist/` returns no hits (exit code 1 = no matches)

## Current State
- All `/r2/` paths have been replaced with `/b2/`
- All `r2.aicodebattle.com` references replaced with `b2.aicodebattle.com`
- Build artifacts in `dist/` are clean (no R2 references)
