🔴 Shared database table loses data when different services use the same key name
The shared persistence table uses only the key column as its primary key (key TEXT PRIMARY KEY at services/python/agent-baas/main.py:39), but the upsert uses ON CONFLICT (key) while the read filters by both key AND service, so when two services write the same key name (e.g., "root", "list_items"), the second service overwrites the first's row including its service column, making the first service's subsequent reads return nothing.
Impact: Any cached or persisted state silently disappears for services that share common endpoint names, causing data loss across dozens of microservices.
Full mechanism: PRIMARY KEY vs composite lookup mismatch
The table is created with key TEXT PRIMARY KEY (no composite key including service). The write path at e.g. services/python/agent-baas/main.py:63 does ON CONFLICT (key) DO UPDATE SET value = $2, updated_at = NOW() — this overwrites the entire row including the service column. But the read path at services/python/agent-baas/main.py:52 queries WHERE key = $1 AND service = $2.
Scenario: Service A (agent-baas) writes key="list_items", service="agent-baas". Service B (art-agent-service) writes key="list_items", service="art-agent-service". The ON CONFLICT (key) triggers and overwrites the row, setting service to "art-agent-service". Now when agent-baas reads WHERE key='list_items' AND service='agent-baas', it gets no rows — the data is gone.
This pattern is replicated identically across 80+ Python services in this PR.
Prompt for agents
The service_state table uses key TEXT PRIMARY KEY but the read queries filter by both key AND service. This means different services sharing the same key name (like 'root', 'list_items', 'get_item') will overwrite each other's rows. The fix is to make the primary key a composite of (key, service) instead of just key. Change the CREATE TABLE to use PRIMARY KEY (key, service) and update the ON CONFLICT clause to ON CONFLICT (key, service). This same boilerplate is copy-pasted across 80+ Python services in services/python/*/main.py, so all instances need the same fix.

🔴 Async database calls in synchronous endpoint handlers crash the service at startup
The await keyword is used inside a regular def function (def root() at services/python/agent-embedded-finance/main.py:210), which is a Python SyntaxError that prevents the module from loading, so the entire service fails to start.
Impact: The agent-embedded-finance service cannot start at all; every request returns a server error.
Full mechanism: await in non-async def
At services/python/agent-embedded-finance/main.py:208, the function is declared as def root(): (synchronous), but line 210 calls await pg_get("root", "agent_embedded_finance"). In Python, await can only be used inside async def functions. This causes a SyntaxError when Python parses the module, preventing the entire FastAPI application from starting.
The same bug appears in:
services/python/agent-scorecard/main.py:208(def root())services/python/cips-integration/main.py:166(def read_root())services/python/fps-integration/main.py:176(def read_root())services/python/data-warehouse/main.py:198-201(multiple syncdeffunctions likecreate_agent,read_agents, etc.)services/python/database/main.py(multiple syncdeffunctions)services/python/infrastructure/main.py:208(def read_root())services/python/hierarchy-service/main.py(multiple syncdeffunctions)- Many others where
def(notasync def) functions containawaitcalls.
Prompt for agents
The pg_get/pg_set persistence code was injected into synchronous def functions using await, which is a SyntaxError in Python. Every function that uses await pg_get() or await pg_set() must be declared as async def. This affects dozens of services where the root() or read_root() endpoint is def (not async def), as well as synchronous CRUD handlers in data-warehouse, database, hierarchy-service, ml-engine, device-management, edge-deployment, and others. Either change these functions to async def, or remove the await pg_get/pg_set calls from synchronous functions.

🔴 Code injected inside FastAPI constructor breaks the service's Python syntax
The startup event handler code is spliced into the middle of the FastAPI() constructor call (services/python/offline-sync/main.py:93-98), producing invalid Python syntax that prevents the service from loading.
Impact: The offline-sync service cannot start; all offline data synchronization is unavailable.
Full mechanism: broken FastAPI() call
At services/python/offline-sync/main.py:92-101, the code reads:
app = FastAPI(
title=get_settings()
@app.on_event("startup")
async def _init_pg_pool():
await get_pg_pool()
.app_name,
apply_middleware(app, enable_auth=True)
description="Service for managing offline synchronization of remittance data.",
version="1.0.0",
)The @app.on_event("startup") decorator and the async def _init_pg_pool function were injected between get_settings() and .app_name, breaking the method chain and the FastAPI constructor call entirely. This is a SyntaxError.
Prompt for agents
The @app.on_event('startup') handler was injected inside the FastAPI() constructor call, between get_settings() and .app_name, breaking the Python syntax. Move the startup event registration to after the FastAPI app is fully constructed. The code at lines 92-101 needs to be restructured so that app = FastAPI(title=get_settings().app_name, description=..., version=...) is a complete statement, and the @app.on_event('startup') decorator comes after it.

🔴 Code injected inside a string literal breaks the financial ledger service's Python syntax
The startup event handler code is spliced into the middle of the FastAPI title string parameter (services/python/tigerbeetle-zig/main.py:281-286), producing invalid Python that prevents the financial ledger service from loading.
Impact: The TigerBeetle financial ledger service cannot start; all ledger operations and balance queries are unavailable.
Full mechanism: code inside string literal
At services/python/tigerbeetle-zig/main.py:280-289, the code reads:
app = FastAPI(
title="TigerBeetle Service (Production)
@app.on_event("startup")
async def _init_pg_pool():
await get_pg_pool()
",
description="Production-ready Financial Ledger...",The startup handler was injected inside the title string, creating a multi-line string that contains Python code as literal text, followed by a closing quote. This is a SyntaxError because the original string was not multi-line.
Prompt for agents
The @app.on_event('startup') handler was injected inside the title string of the FastAPI() constructor at services/python/tigerbeetle-zig/main.py:280-289. The title parameter should be a simple string like 'TigerBeetle Service (Production)', and the startup event handler should be placed after the FastAPI app is fully constructed.

🔴 Two Dapr services assigned the same network port will fail to run simultaneously
The service registry assigns port 9500 to both "ddos-shield" (Rust) and "tigerbeetle-orchestrator" (Python) (server/middleware/middlewareConnectors.ts:1298 and server/middleware/middlewareConnectors.ts:1304), so only one can bind successfully when both are deployed.
Impact: Either the DDoS protection or the TigerBeetle orchestrator will fail to start, leaving one of those capabilities unavailable.
Port collision details
At server/middleware/middlewareConnectors.ts:1298: "ddos-shield": { appId: "ddos-shield", port: 9500, language: "rust" }
At server/middleware/middlewareConnectors.ts:1304: "tigerbeetle-orchestrator": { appId: "tigerbeetle-orchestrator", port: 9500, language: "python" }
Both services are registered with port 9500. When deployed on the same host, the second service to start will get an EADDRINUSE error.

🔍 Dashboard load fetches data but never stores it, making the network call pointless
At mobile-flutter/mobile-flutter/lib/screens/pos_enhanced_dashboard_screen.dart:44-50, _loadDashboard() fetches data via ApiService.get('/pos/dashboard/summary') and stores it in a local data variable, but the setState callback is empty ({ /* loaded */ }). The fetched data is never assigned to any state variable, so the widget tree never updates with the dashboard data. The entire network call has no effect on the UI.

🔍 QR scanner screen has no actual camera integration — only a static placeholder UI
The previous QrScannerScreen at mobile-flutter/mobile-flutter/lib/screens/qr_scanner_screen.dart used the mobile_scanner package with MobileScanner(onDetect: ...) to actually scan QR codes via the device camera. The new implementation removes this import and replaces it with a static UI showing an icon and text "Point camera at QR code" but has no mechanism to actually capture or process QR codes. The _processQrCode(String data) method exists but is never called from anywhere in the widget. Users will see a scanner UI that doesn't scan anything.

🟥 Cache returns one agent's financial data to all other agents due to non-parameterized cache keys
The pg_get cache lookup uses only the function name as the key (e.g., "get_agent_float") without including the agent_id path parameter (services/python/agent-baas/main.py:157). If any value is ever written to this key, ALL subsequent requests for ANY agent's float balance will return that single cached value, leaking one agent's financial data (balance, allocations, daily limits) to every other agent who queries the endpoint.

🟥 Dashboard and business data endpoints return cached data that ignores the requesting user's identity
Multiple dashboard and analytics endpoints in services/python/agent-business-dashboard/main.py:131-137 use a static cache key like pg_get("get_dashboard_overview", ...) that does not incorporate the agent_id path parameter. If the cache is populated with one agent's dashboard data, all other agents will see that same data, exposing revenue figures, transaction counts, and performance metrics across organizational boundaries.

🟨 Permission enforcement uses fallback user ID '0' when authentication context is missing
The enforcePermission calls across multiple routers (e.g., server/routers/agentLoanFacility.ts:163) use String(ctx.user?.id ?? "0") as the subject ID. If ctx.user is unexpectedly null or undefined, the permission check runs with subject ID "0" instead of failing, potentially granting access if the permission system treats "0" as a valid or privileged user.
