Deployment integration with Sentry

Severity: Recommended

When Sentry knows about deployments, you can answer "did this deploy break something?" and filter errors by release.

Check automatically:

1. Check for release creation in CI/CD:

# Sentry release in CI
grep -riE "sentry-cli.*releases|sentry.*release|SENTRY_RELEASE" .github/workflows/*.yml .gitlab-ci.yml 2>/dev/null

2. Check for release config in Sentry init:

# Release in Sentry.init
grep -A 30 "Sentry.init" --include="*.ts" --include="*.js" --include="*.tsx" src/ lib/ app/ 2>/dev/null | grep -iE "release|environment"

3. Check for deploy notification:

# Deploy finalization
grep -riE "sentry-cli.*releases.*finalize|sentry-cli.*releases.*deploys" .github/workflows/*.yml package.json 2>/dev/null

4. Check how release is set:

# Release from git or env
grep -riE "release.*process\.env|release.*GIT|release.*COMMIT|release.*SHA|release.*VERSION" --include="*.ts" --include="*.js" src/ lib/ app/ config/ 2>/dev/null | head -5

If not found in code, ask user:

• "Does Sentry know when deployments happen?"
• "Can you filter Sentry errors by release version?"
• "When a deploy goes out, can you see 'new errors in this release' in Sentry?"

Cross-reference with:

• ERR-004 (source maps are tied to releases)
• DEPLOY-004 (deployment tagging)

Pass criteria:

• release set in Sentry.init (from git SHA, version, or env var)
• Release created in Sentry during CI/CD (sentry-cli releases new)
• Deploy notification sent (sentry-cli releases deploys new)
• Can filter errors by release in Sentry dashboard

Fail criteria:

• No release configured (all errors lumped together)
• Release set but never created in Sentry (orphaned release)
• No way to correlate errors with specific deployments

Partial (acceptable):

• Release set but no deploy notification (you see releases but not deploy timestamps)
• Release is git SHA only (works but less human-readable than semver)

Evidence to capture:

• Release configuration method
• CI/CD steps for release creation
• Sample Sentry view showing release filtering
