Fix critical 401 authentication bug in Edge Functions and add CI/CD
This commit resolves a critical bug where function-to-function calls failed with 401 "Invalid JWT" errors, and implements comprehensive testing to prevent regression. ROOT CAUSE: - Deno.env.get('SUPABASE_SERVICE_ROLE_KEY') returns a 41-char internal ID - The real service role JWT is 219+ chars and stored in Supabase Vault - Edge functions cannot access vault directly, only via SECURITY DEFINER RPC SOLUTION: - Created get_service_role_key() PostgreSQL RPC function to access vault - Updated sync-all-devices to use supabase.rpc('get_service_role_key') - Fixed all tracker_id → device_id schema migrations in transformers - Created permanent test fixtures (echo-test, caller-test) for regression CI/CD INTEGRATION: - Pre-commit hook (.husky/run-supabase-tests.sh) runs tests locally - GitHub Actions workflow runs full test suite on PR/push - Tests verify RPC exists and code uses correct auth pattern DOCUMENTATION: - TROUBLESHOOTING.md - Comprehensive bug guide and solutions - INTEGRATION_GUIDE.md - Step-by-step checklist for new integrations - POSTMORTEM_401_AUTH_BUG.md - Incident timeline and lessons learned - README_EDGE_FUNCTIONS.md - Architecture overview - FUNCTION_TO_FUNCTION_AUTH_TEST.md - Test documentation TESTING: - Manual SQL test suite in tests/function-to-function-auth.test.sql - Automated pre-commit verification - GitHub Actions CI/CD pipeline - Permanent test functions prevent future regressions IMPACT: - Fitbit: 898 records synced successfully - Whoop: 3 records synced successfully - All function-to-function calls now working Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# GitHub Actions Workflows

## Supabase Edge Function Tests
4+
5+
**File:** `supabase-tests.yml`
6+
7+
**Purpose:** Prevent reintroduction of the 401 "Invalid JWT" authentication bug in Supabase Edge Functions.
8+
9+
**Triggers:**
10+
- Pull requests to `main` branch
11+
- Pushes to `main` branch
12+
- Only runs when files in `supabase/` directory are modified
13+
14+
**What It Tests:**
15+
16+
1. **RPC Function Verification:**
17+
- Checks that `public.get_service_role_key()` function exists in database
18+
- This function is CRITICAL for function-to-function authentication
19+
- If missing, edge functions will fail with 401 errors
20+
21+
2. **Code Pattern Verification:**
22+
- Ensures `sync-all-devices` uses `supabase.rpc('get_service_role_key')`
23+
- Detects if code incorrectly uses `Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')`
24+
- The env var is only 41 chars (internal ID), not the 219-char JWT needed
25+
26+
3. **Full Regression Test Suite:**
27+
- Runs `supabase/tests/function-to-function-auth.test.sql`
28+
- Tests both direct function calls and nested function-to-function calls
29+
- Uses permanent test fixtures: `echo-test` and `caller-test` functions
30+
31+
**Requirements:**
32+
- Repository secret `DATABASE_URL` must be configured
33+
- Database must have vault secrets configured
34+
- PostgreSQL client (automatically installed in workflow)
35+
36+
**Workflow will skip if:**
37+
- No files in `supabase/` directory were modified
38+
- `DATABASE_URL` secret is not configured (shows as skipped, not failed)
39+
40+
**Setup:**
41+
42+
1. Add repository secret:
43+
- Go to Settings → Secrets and variables → Actions
44+
- Add `DATABASE_URL` with value: `postgresql://postgres:[password]@[host]:[port]/postgres`
45+
46+
2. Ensure database has required migrations applied:
47+
```bash
48+
psql $DATABASE_URL -f supabase/migrations/20260203194800_add_get_service_role_key_function.sql
49+
```
50+
51+
**Viewing Results:**
52+
- Check the "Actions" tab in GitHub repository
53+
- Look for workflow run named "Supabase Edge Function Tests"
54+
- All checks must pass before merging pull requests
55+
56+
**Related Documentation:**
57+
- See `supabase/TROUBLESHOOTING.md` for details on the 401 bug
58+
- See `supabase/POSTMORTEM_401_AUTH_BUG.md` for incident history
59+
- See `supabase/tests/function-to-function-auth.test.sql` for test details
60+
61+
**Troubleshooting:**
62+
63+
If workflow fails:
64+
65+
1. **"get_service_role_key() RPC function missing":**
66+
- Apply migration: `supabase/migrations/20260203194800_add_get_service_role_key_function.sql`
67+
- Or run: `npx supabase db push`
68+
69+
2. **"sync-all-devices uses env var instead of vault RPC":**
70+
- Someone modified `sync-all-devices/index.ts` incorrectly
71+
- Must use: `await supabase.rpc('get_service_role_key')`
72+
- See `supabase/TROUBLESHOOTING.md` for correct pattern
73+
74+
3. **"Full regression test suite failed":**
75+
- Check database connectivity
76+
- Verify vault secrets are configured
77+
- Review test output for specific failures
78+
- Run tests manually: `psql $DATABASE_URL -f supabase/tests/function-to-function-auth.test.sql`
79+
80+
## Adding New Workflows
81+
82+
When adding new workflows to this directory:
83+
84+
1. Name files descriptively: `feature-name.yml`
85+
2. Add documentation section in this README
86+
3. Use specific triggers (avoid `on: [push]` for all branches)
87+
4. Add proper job conditions to skip unnecessary runs
88+
5. Include clear error messages in failure steps
89+
6. Document required secrets and setup steps
