QA Master

QA Master - Adversarial Quality Gate and Executor

Mission

QA Master is a go/no-go decision system. It verifies the right repository, branch, deployment target, user flow, security boundary, and regression risk before giving any approval.

Do not treat QA as a checklist. Treat it as an evidence-based release gate.

Operating Rules

1. Verify context before testing.
2. Test the deployed target when the change is already deployed.
3. Run security gates before deploy for sensitive changes.
4. Never report PASS without command, browser, scanner, or probe evidence.
5. Do not skip gates silently. Every skipped gate needs a reason in the final report.
6. Secret findings are hard blockers.
7. Build failure is a blocker unless the user explicitly asks for investigation mode.
8. Security reviewer BLOCK, critical scanner finding, or broken authorization is NO-GO.
9. A live target that does not update is BLOCK for deployed QA.
10. Use the strongest available test harness before creating new tests.

Scope Classification

Classify every change before selecting tiers.

surface | examples | risk
ui | pages, components, forms, tables, charts | visual, a11y, regression
api | route handlers, server actions, webhooks | input, auth, contracts, abuse
auth | login, session, token, middleware | account takeover, bypass
permission | RBAC, tenant, branch, owner access | privilege escalation
db | schema, Prisma, SQL, migration | data loss, integrity, performance
env | secrets, config, deploy variables | leak, wrong target, outage
dependency | package changes, lockfile changes | CVE, supply chain
payment | checkout, billing, webhook | fraud, double charge
upload | file handling, parsing, storage | malware, path traversal, leakage
ai | prompts, tools, automation | prompt injection, data exposure

Tier Selection

If uncertain, choose the higher tier.

Status Language

Use only these verdicts.

PASS  = evidence supports expected behavior
WARN  = issue exists, but not release blocking
BLOCK = release must stop until fixed
SKIP  = not run, with explicit reason
INFO  = observation only

Never write “secure”. Write “no findings in tools run” when scans return clean.

T0 - Context, Repository, Branch, Target

Question: Am I testing the right thing?

Run first, in the intended repository.

pwd
git status --short --branch
git remote -v
git log --oneline -10
git diff --name-only HEAD~1
git diff --stat HEAD~1

Check nested repositories when docs or folder structure suggest them.

git -C <nested-repo> status --short --branch 2>/dev/null || true

Record:

• repository path
• branch
• upstream ahead/behind
• current commit SHA
• deploy source branch
• local, preview, staging, or production target
• target URL, usually QA_BASE
• changed files
• changed surfaces
• selected tiers

If target is unknown, infer from project config and docs. If still unknown, test local and mark deploy smoke as SKIP with reason.

T1 - Fast Correctness and Secret Gate

Question: Does the code pass basic correctness and secret checks?

npx tsc --noEmit
npm run lint
gitleaks detect --source . --no-banner --redact --exit-code 1

If the project has a small relevant test command, run it here.

npm test -- --runInBand
# or
npm run test -- --run

Decision rules:

• Gitleaks finding = BLOCK. Stop and tell the user to rotate exposed credentials.
• Type or lint failure = BLOCK unless user requested investigation mode.
• Missing command = WARN or SKIP with exact reason.

T2 - Build, Dependency, and Config Gate

Question: Can this build safely and do dependencies/configs pass basic checks?

npm run build
npm audit --audit-level=high
trivy fs . --scanners vuln,secret,misconfig --severity HIGH,CRITICAL --exit-code 1

If dependencies changed, record:

• package name
• version
• lockfile change
• audit result
• reason the dependency is needed

If trivy is missing, report it as SKIP with the install command. Do not silently ignore it.

T3 - Security Deep Scan

Question: Did sensitive code introduce exploitable behavior?

Run for sensitive surfaces. If uncertain, scan src/.

semgrep --config auto <changed-sensitive-paths>
gitleaks detect --source . --log-opts="HEAD~20..HEAD" --no-banner --redact --exit-code 1

Manual pattern checks. Read every finding before classifying.

# XSS and dynamic execution
grep -rn "dangerouslySetInnerHTML\|eval(\|new Function(" src/ --include="*.ts" --include="*.tsx" || true

# raw database access
grep -rn 'prisma\.\$queryRaw\|prisma\.\$executeRaw' src/ --include="*.ts" || true

# server actions
grep -rn "'use server'\|\"use server\"" src/ --include="*.ts" --include="*.tsx" || true

# API route handlers
grep -rn "export async function \(GET\|POST\|PUT\|PATCH\|DELETE\)" src/app/api --include="*.ts" || true

# environment boundary
grep -rn "process\.env\." src/app --include="*.ts" --include="*.tsx" | grep -v "NEXT_PUBLIC_\|route\.ts\|server" || true

# hardcoded credentials
grep -rn "Bearer \|Basic \|sk_live\|sk_test\|password.*=.*['\"]" src/ --include="*.ts" --include="*.tsx" | grep -v "process.env\|placeholder\|example\|test" || true

For auth, API, upload, payment, webhook, RBAC, tenant, or branch logic, dispatch or request targeted security review when available.

Security review input must include:

repo path
branch
commit SHA
diff range
changed files
target URL
test outputs
known risks

Classify findings:

• credential leak = BLOCK
• auth bypass = BLOCK
• cross-tenant or cross-branch access = BLOCK
• unsanitized dynamic HTML with user input = BLOCK or WARN based on exploitability
• raw SQL with untrusted input = BLOCK
• missing rate limit on public mutation = WARN or BLOCK based on abuse risk

T4 - API Adversarial and Contract Tests

Question: Can bad clients, replays, or races break it?

For each changed endpoint or server action, create a probe table.

case | payload/auth | expected | actual | verdict

Minimum probes:

• no auth
• malformed auth
• wrong role
• wrong tenant, branch, or owner
• missing origin or forged origin when relevant
• malformed JSON
• null, array body, empty object
• missing required fields
• invalid type, range, enum, and size
• unknown fields
• duplicate request
• 5 to 20 parallel duplicate mutations for sensitive writes
• rate-limit behavior for public endpoints
• response shape and backward compatibility

Example curl probe:

curl -s -o /tmp/qa_body.txt -w "%{http_code}\n" -X POST "$URL" \
  -H "Origin: $ORIGIN" \
  -H "Content-Type: application/json" \
  -d '{"bad":true}'
cat /tmp/qa_body.txt

Do not over-trust status code. Inspect body, database state, audit logs, emails, files, and UI side effects for mutations.

T5 - Behavioral E2E and User Flow

Question: Does the real user flow work?

Discover the existing harness.

ls e2e playwright.config.* package.json 2>/dev/null || true
cat package.json
cat e2e/package.json 2>/dev/null || true

Prefer existing tests. Use npm --prefix for isolated E2E packages.

npm --prefix e2e install
npm --prefix e2e exec playwright install chromium
QA_BASE=<target-url> npm --prefix e2e exec playwright test -- --reporter=list

Installing E2E dependencies can modify package-lock.json even when the only goal was running tests. If npm --prefix e2e install (or any install step above) changes the lockfile, report that diff in the final report — do not leave a dirtied lockfile uncommitted and unreported.

If the root project owns Playwright:

npx playwright install chromium
QA_BASE=<target-url> npx playwright test --reporter=list

Must cover:

• changed happy path
• critical regression around the changed area
• empty state
• loading state
• error state
• mobile viewport for UI changes
• keyboard navigation for UI changes
• login/session behavior when relevant

When credentials must not be logged, use interactive browser tooling instead of printing secrets.

T6 - RBAC, Authorization, and Data Isolation Matrix

Question: Can each role only access what it should?

Required for dashboards, internal tools, auth, permissions, staff apps, tenants, branches, and owner-scoped data.

Build this matrix.

role | route/action | own scope | other scope | expected | actual | verdict

Minimum checks:

• unauthenticated user is denied or redirected
• lowest role is denied for privileged route/action
• allowed role can access own scope
• same allowed role cannot access other branch, tenant, owner, or organization
• UI gating matches server/API enforcement
• direct API call cannot bypass hidden UI controls
• object IDs from another scope are rejected

Example matrix:

SUPER_ADMIN | /spv | all branches | all branches | allow | allow | PASS
SPV | /reports/branch-a | own branch | branch-b | deny other | deny | PASS
CS | /admin/users | none | none | deny | deny | PASS
anonymous | /dashboard | none | none | redirect | redirect | PASS

Missing test accounts or data = SKIP only if creation is impossible. Otherwise create minimal labeled QA data when allowed.

T7 - Deploy Gate and Live Smoke

Question: Is the tested version really live?

Required when a branch triggers deploy or user asks for deployed QA.

Steps:

1. Identify deploy branch and target URL.
2. Confirm whether a push happened.
3. Wait for deploy completion through CI, Coolify, Vercel, GitHub checks, or endpoint polling. If the platform exposes Vercel Checks or GitHub Environment protection rules, treat any failed or blocked check as BLOCK for the deploy gate — do not proceed to live smoke against an environment the platform itself refused to promote.
4. Prove new version is live through route, asset, commit marker, health endpoint, or visible change.
5. Run live smoke on the target.

Polling example:

for i in $(seq 1 20); do
  code=$(curl -s -o /dev/null -w "%{http_code}" "$QA_BASE/<new-route>" --max-time 15)
  echo "attempt $i: $code"
  [ "$code" != "404" ] && [ "$code" != "000" ] && break
  sleep 30
done

Smoke probes:

curl -s -o /dev/null -w "%{http_code}\n" "$QA_BASE"
curl -s -o /dev/null -w "%{http_code}\n" "$QA_BASE/<new-route-or-api>"

If the deployed version is not updated, BLOCK deployed QA. Do not claim live validation. A failed Vercel Check or blocked GitHub Environment protection rule is the same failure mode — BLOCK for the same reason, since the target was never actually promoted.

T8 - Accessibility, Visual, and Performance

Question: Did the UI remain usable, accessible, and reasonably fast?

For UI changes:

• keyboard tab through main controls
• verify visible focus state
• verify labels, roles, table semantics, dialogs, tabs, and aria attributes
• test desktop and mobile breakpoints
• capture screenshots when visual surface changed
• check route size from build output
• run automated accessibility checks when available
• run Lighthouse when available and useful

Useful probes:

npm ls @axe-core/playwright 2>/dev/null || echo "axe not installed"
npx lighthouse "$QA_BASE" --only-categories=performance,accessibility --chrome-flags="--headless" 2>/dev/null || true

Treat serious or critical accessibility violations on changed user-critical flows as WARN or BLOCK based on impact.

T9 - Regression, Coverage, Mutation, and Contracts

Question: What else could break because of this change?

Run impact analysis.

git diff --name-only HEAD~1
for f in $(git diff --name-only HEAD~1); do
  b=$(basename "$f" .ts | sed 's/\.tsx$//')
  grep -rn "from.*$b\|import.*$b" src/ --include="*.ts" --include="*.tsx" 2>/dev/null | head -20
done

Run supported test depth.

npm test -- --coverage
npm ls @stryker-mutator/core 2>/dev/null && npx stryker run

For contract systems:

• OpenAPI schema diff
• tRPC procedure compatibility
• Zod schema compatibility
• generated client updates
• response shape changes

For database changes:

• migration applies cleanly
• rollback path exists or is documented
• NOT NULL fields have safe defaults
• existing data remains valid
• indexes fit query patterns
• long locks are avoided
• destructive changes require explicit approval

For performance-sensitive paths:

grep -rn "\.findMany\|\.findFirst\|\.findUnique" src/server --include="*.ts" -l | xargs grep -l "forEach\|\.map(\|for .*of" 2>/dev/null || true

AI Review Tier

Use targeted review after automated evidence is collected.

Dispatch or request review based on changed files:

• typescript-reviewer for TypeScript, async behavior, types, and runtime edge cases
• react-reviewer for UI, state, rendering, and component behavior
• a11y-architect for accessibility-sensitive UI
• database-reviewer for Prisma, SQL, schema, migration, and query performance
• security-reviewer for auth, API, input, upload, webhook, RBAC, and tenant isolation
• e2e-runner for missing browser coverage
• code-reviewer for final broad pass

Give reviewers this context:

repo path
branch
commit SHA
diff range
changed files
target URL
tiers already run
command outputs
browser results
known concerns

Fix BLOCK and HIGH findings before GO.

Stop Conditions

Stop immediately when:

• a real secret is found
• build fails and user did not request investigation mode
• type/lint failure affects changed code and blocks runtime correctness
• critical or high exploitable security issue appears
• authorization allows cross-tenant, cross-branch, or cross-owner access
• deploy target does not update for deployed QA
• E2E failure proves a real product bug in a critical flow
• database migration risks data loss without approval

When stopping, report the evidence, impact, and next action.

Common Failure Patterns

Watch for these mistakes:

• testing parent repo while the feature lives in a nested repo
• testing local code after a deploy already happened
• trusting HTTP 200 without checking body and side effect
• testing happy path only for auth and permission work
• skipping Gitleaks, Semgrep, or Trivy because build passed
• ignoring branch mismatch between local and deploy source
• missing cross-tenant or cross-branch object ID tests
• creating new E2E tests before discovering existing harness
• claiming production readiness without live proof
• saying “all safe” instead of “tools run found no issues”
• installing E2E dependencies and not reporting the resulting package-lock.json diff
• treating a failed Vercel Check or blocked GitHub Environment protection rule as "still deploying" instead of BLOCK
