 Deliverables 

 Repo Scaffold 

 
 Gradle Kotlin/Ktor project structure (per ~/system/blueprints/types/kotlin-ktor.json ) 
 .gitignore , .env.example , BUILD-BLUEPRINT.md 
 CI config: GitHub Actions (lint, compile, test) 
 docker-compose.yml : Postgres 16 + Unleash + app service 
 

 Database Foundation 

 
 Flyway V1 baseline migration: organization , venue , restaurant_table , staff , role 
 RLS ENABLED + FORCED on restaurant_table and staff 
 Two DB roles:
 
 qody_flyway : DDL/migration owner (BYPASSRLS allowed, NOT used at runtime) 
 qody_app : Runtime role (NOBYPASSRLS, NOT table owner) 
 
 
 RLS policies:
 
 PERMISSIVE ALL policy: venue_id = current_setting('app.current_venue_id', true)::uuid 
 RESTRICTIVE INSERT policy: prevents cross-tenant writes 
 
 
 

 API Foundation 

 
 Ktor app with /health endpoint 
 HikariCP connection pool (Phase 1: wire SET ROLE qody_app in connectionInitSql ) 
 Fail-closed RLS role verification on boot:
 fun verifyRlsRoleFailClosed() {
 val result = transaction {
 exec("SELECT rolname, rolbypassrls FROM pg_roles WHERE rolname = 'qody_app'") { rs ->
 if (rs.next()) {
 val bypassRls = rs.getBoolean("rolbypassrls")
 if (bypassRls) {
 throw IllegalStateException(
 "SECURITY VIOLATION: qody_app has BYPASSRLS. App refuses to start."
 )
 }
 }
 }
 }
 logger.info("RLS self-check PASS: qody_app has BYPASSRLS=false")
}
 
 
 

 Frontend Foundation 

 
 3 MFE shells (Vite + React):
 
 guest-mfe/ : Public QR menu (port 5173) 
 staff-mfe/ : Kitchen/staff board (port 5174) 
 admin-mfe/ : Venue dashboard (port 5175) 
 
 
 Each MFE independently deployable (separate build/deploy) 
 

 Validation Evidence (Proveo) 

 Test 1: /health Check — RLS Role Self-Check (PASS) 

 curl -s -i http://localhost:8088/health

HTTP/1.1 200 OK
{
 "status":"ok",
 "version":"0.1.0",
 "db":{
 "connected":true,
 "rlsRoleCheck":{
 "role":"qody_app",
 "bypassRls":false,
 "status":"PASS"
 }
 }
}
 

 Verdict: PASS. HTTP 200. rlsRoleCheck.bypassRls=false , status="PASS" . qody_app confirmed NOBYPASSRLS at runtime. 

 Test 2: RLS ENABLED + FORCED on Tenant Tables (PASS) 

 SELECT relname AS table_name, relrowsecurity AS rls_enabled, relforcerowsecurity AS rls_forced
FROM pg_class WHERE relname IN ('restaurant_table', 'staff') ORDER BY relname;

 table_name | rls_enabled | rls_forced
------------------+-------------+------------
 restaurant_table | t | t
 staff | t | t
(2 rows)
 

 Verdict: PASS. Both tenant tables have RLS ENABLED (t) and FORCED (t). 

 Test 3: RLS Policies — PERMISSIVE USING + RESTRICTIVE INSERT (PASS) 

 SELECT tablename, policyname, permissive, cmd
FROM pg_policies WHERE tablename IN ('restaurant_table', 'staff') ORDER BY tablename, policyname;

 tablename | policyname | permissive | cmd
------------------+-----------------------------------+-------------+--------
 restaurant_table | tenant_insert_restaurant_table | RESTRICTIVE | INSERT
 restaurant_table | tenant_isolation_restaurant_table | PERMISSIVE | ALL
 staff | tenant_insert_staff | RESTRICTIVE | INSERT
 staff | tenant_isolation_staff | PERMISSIVE | ALL
(4 rows)
 

 Verdict: PASS. Both tables have PERMISSIVE USING policy (filters reads) and RESTRICTIVE INSERT policy (rejects cross-tenant writes). 

 Test 4: Two-Venue RLS Isolation (Core Tenant Isolation Test) 

 Setup (as qody_flyway / table owner): 

 venue A: id=6d1b9c47-c088-4808-8473-e8b1672c7acc name="Alpha Bistro"
venue B: id=fcf66a03-ef67-41bd-9d6b-348b0ee9908a name="Beta Grill"

restaurant_table rows seeded:
 Table A1 -> venue A
 Table A2 -> venue A
 Table B1 -> venue B
 Table B2 -> venue B
 

 Test 4a: Context = venue A — venue B rows INVISIBLE (as qody_app) 

 BEGIN;
SET LOCAL app.current_venue_id = '6d1b9c47-c088-4808-8473-e8b1672c7acc';
SELECT label, venue_id FROM restaurant_table ORDER BY label;
ROLLBACK;

 label | venue_id
----------+--------------------------------------
 Table A1 | 6d1b9c47-c088-4808-8473-e8b1672c7acc
 Table A2 | 6d1b9c47-c088-4808-8473-e8b1672c7acc
(2 rows)
 

 Verdict: PASS. Only 2 venue-A rows returned. Venue B rows (Table B1, Table B2) are invisible. 

 Test 4b: Context = venue A — INSERT with venue_id=B REJECTED (as qody_app) 

 BEGIN;
SET LOCAL app.current_venue_id = '6d1b9c47-c088-4808-8473-e8b1672c7acc';
INSERT INTO restaurant_table (venue_id, label, qr_token_id, capacity)
 VALUES ('fcf66a03-ef67-41bd-9d6b-348b0ee9908a', 'Smuggled B3', 'qr-smuggled', 2);
ROLLBACK;

ERROR: new row violates row-level security policy for table "restaurant_table"
 

 Verdict: PASS. Cross-tenant INSERT correctly rejected by RESTRICTIVE insert policy. 

 Test 4c: Context = venue B — venue A rows INVISIBLE (symmetric isolation) 

 BEGIN;
SET LOCAL app.current_venue_id = 'fcf66a03-ef67-41bd-9d6b-348b0ee9908a';
SELECT label, venue_id FROM restaurant_table ORDER BY label;
ROLLBACK;

 label | venue_id
----------+--------------------------------------
 Table B1 | fcf66a03-ef67-41bd-9d6b-348b0ee9908a
 Table B2 | fcf66a03-ef67-41bd-9d6b-348b0ee9908a
(2 rows)
 

 Verdict: PASS. Only 2 venue-B rows returned. Venue A rows (Table A1, Table A2) invisible. 

 Test 5: No Context Set — Zero Rows Returned (PASS) 

 -- As qody_app, no SET of app.current_venue_id
SELECT label, venue_id FROM restaurant_table ORDER BY label;

 label | venue_id
-------+----------
(0 rows)
 

 Verdict: PASS. Fail-safe: no context = no rows returned. No cross-tenant data leakage. 

 Test 6: Fail-Closed Negative — BYPASSRLS Simulation (PASS) 

 Step 1: Grant BYPASSRLS to qody_app (as qody_flyway) 

 ALTER ROLE qody_app BYPASSRLS;

SELECT rolname, rolbypassrls FROM pg_roles WHERE rolname = 'qody_app';

 rolname | rolbypassrls
----------+--------------
 qody_app | t
(1 row)
 

 Step 2: Prove /health returns HTTP 500 with BYPASSRLS active (live app) 

 curl -s -i http://localhost:8088/health

HTTP/1.1 500 Internal Server Error
{
 "status":"degraded",
 "version":"0.1.0",
 "db":{
 "connected":true,
 "rlsRoleCheck":{
 "role":"qody_app",
 "bypassRls":true,
 "status":"FAIL"
 }
 }
}
 

 Verdict: PASS. /health correctly returns HTTP 500 + status:"FAIL" when BYPASSRLS is active. 

 Step 3: Prove the Bilko breach — BYPASSRLS silently exposes all tenant data 

 -- As qody_flyway with SET ROLE qody_app (who now has BYPASSRLS)
SET ROLE qody_app;
SET LOCAL app.current_venue_id = '6d1b9c47-c088-4808-8473-e8b1672c7acc'; -- context = venue A
SELECT label, venue_id FROM restaurant_table ORDER BY label;

 label | venue_id
----------+--------------------------------------
 Table A1 | 6d1b9c47-c088-4808-8473-e8b1672c7acc
 Table A2 | 6d1b9c47-c088-4808-8473-e8b1672c7acc
 Table B1 | fcf66a03-ef67-41bd-9d6b-348b0ee9908a
 Table B2 | fcf66a03-ef67-41bd-9d6b-348b0ee9908a
(4 rows)
 

 Evidence: With BYPASSRLS, even with app.current_venue_id scoped to venue A, ALL 4 rows across both venues are returned. This is the exact Bilko breach reproduced. The fail-closed /health check is not cosmetic — it is the guard against this silent breach. 

 Step 4: Restore safe state 

 ALTER ROLE qody_app NOBYPASSRLS;

curl -s -i http://localhost:8088/health
-> HTTP/1.1 200 OK ... "bypassRls":false,"status":"PASS"
 

 Verdict: PASS. Reverted cleanly. /health confirms restored to safe state.

 Gaps / Phase 1 Actions 

 
 Runtime role switch not yet wired: The app currently connects to Postgres as qody_flyway (the owner/DDL role) for both Flyway migrations AND runtime queries. Phase 1 must wire connectionInitSql = "SET ROLE qody_app" in HikariCP config before any data-carrying endpoint is live. 
 Flyway baseline note: The V1 migration was applied manually (no Flyway schema history table initially). For production/CI this must be handled via flyway.baselineOnMigrate=true in initial deploy or by ensuring Flyway runs against a clean DB.
