Corrections to previous docs: Old reports claimed 14 RLS tables (actual: 18), 30+ tables (actual: 33 active + 3 deprecated), 4 uvicorn workers (actual: 1), S3 bucket thea-portfolio-analytics-storage (actual: industrial-labs-client-files).

3. Security Findings

Discovered by adversarial cross-checking between 6 analysis agents. Each finding independently confirmed by 2+ agents.

Sev	Finding	Location	Details	Confirmed By
P0	`require_role("admin")` passes for ANY user	`billing_routes.py:540`	"admin" is not in ROLE_HIERARCHY (`dependencies.py:185-190`). `get("admin",0)` returns 0, so any authenticated user passes. Endpoint `POST /api/admin/backfill-invoice-pdfs` exposed to all. Uses superuser pool (bypasses RLS), no org_id filter. Limited blast radius: PDF regeneration only.	verifier portal-core admin-client
P1	All billing routes lack RBAC	`billing_routes.py`	create-checkout-session, update-subscription, create-evergreen-fund, generate-forecast use session-only auth with NO role checks. Any viewer can create checkouts and modify subscriptions.	portal-core verifier
P1	Cluster logging silently fails (missing auth token)	`run_job.py:69-70`	`_portal_log_worker()` does NOT send `X-Cluster-Token` header but `model_run_routes.py:551` requires it. All cluster log delivery fails 403. Fix: add `req.add_header('X-Cluster-Token', os.getenv('CLUSTER_API_TOKEN',''))`	cluster-model verifier
P1	No CSRF middleware despite docs claiming complete	`main.py`	SCALE_PLAN Phase 1c marked "Session Timeout & CSRF" as COMPLETED. Session timeout done (max_age=3600) but NO CSRFMiddleware in main.py.	verifier
P1	RLS startup verification gap	`main.py:160-191`	Startup checks RLS on 12 tables but 18 actually have RLS. 6 tables from migrations 005, 012, 013, 019 never verified.	verifier database
P2	Unauthenticated endpoints bypass RLS	`portal_routes.py:569-777`	`/api/funds/{hash}/last-posteriors` and `/api/funds/{hash}/market-stats` have NO auth. market-stats uses superuser pool to bypass RLS.	portal-core admin-client verifier
P2	Cluster token timing attack	`model_run_routes.py:13-20`	Uses `==` not `hmac.compare_digest()`. Migration Lambda correctly uses hmac.	portal-core
P2	`/health/all` leaks infrastructure details	health_routes.py	Exposes S3 bucket name and Ray address without authentication.	infrastructure
P2	Session cookie secure flag not set	`main.py:48`	SessionMiddleware does not set `https_only=True`. Cookies sent over HTTP.	portal-core
P2	6 files bypass s3_helpers.py	database.py, admin_routes.py, job_worker.py, portal_worker.py	Create own `boto3.client('s3')` instead of using centralized s3_helpers. Inconsistent config.	verifier
P2	Stale S3 bucket in run_job.py	`run_job.py:1958`	Default `industrial-labs-portal-uploads` differs from `industrial-labs-client-files` everywhere else.	portal-core
P2	Dual-timeout inconsistency	`portal_worker.py:47` vs `run_job.py`	Portal: 3600s, Cluster: 7200s. Jobs can appear timed out but still complete.	infrastructure
P3	12 undocumented API routes	`config_history_routes.py`	All check `is_super_admin()` — no auth gap, just docs gap.	verifier

Resolved (Non-Issues)

Claim	Resolution	Resolved By
RESOLVED 0-indexed vs 1-indexed bug in `compute_estimation_status()`	NOT A BUG. Full trace: `portal_worker.py:749` sets `end_week = row_count` (1-indexed). Passes through cluster unchanged. `database.py:9151` compares `last_estimated_week == current_row_count` = 55 == 55 = CORRECT. SYSTEM_REFERENCE.md claim is outdated.	database infrastructure

4. Portal Core

Analyzed by: portal-core | Full findings: findings_portal_core.md

4.1 Application Entry Point & Startup

FastAPI app at main.py:26-30, titled "Thea Portfolio Analytics Portal" v0.1.0. Served via Uvicorn on port 8080 (run.sh:12).

Startup Sequence (main.py:125-330)

Pool reset (main.py:133-135) — avoids stale psycopg2 connections after fork
Table creation (main.py:139-156) — 15+ ensure_* functions
RLS verification (main.py:160-191) — checks 12 of 18 RLS tables GAP
Invoice backfill (main.py:201-321) — regenerates all invoice PDFs at startup
Public IP logging (main.py:324-329)

4.2 Middleware Chain (5 Layers)

#	Middleware	Location	Purpose
1	AddinNoCacheMiddleware	`main.py:65-76`	No-cache for `/static/addin/*`
2	SlowAPIMiddleware	`main.py:54`	Rate limiting (100/min default)
3	LoggingMiddleware	`main.py:49`, `middleware.py:24-71`	Request ID, user/org, timing
4	SessionMiddleware	`main.py:48`	Starlette sessions (max_age=3600s)
5	CORSMiddleware	`main.py:33-47`	Portal + Office/Excel origins

4.3 Authentication (3 Mechanisms)

Mechanism	Users	How	Location	Issues
Cognito Session	Browser	OAuth2 code flow, RS256 JWT, TOTP MFA, session cookie 1hr	`auth_routes.py:44-427`	Cookie secure flag not set
API Key	Excel	`sk_live_` prefix, SHA-256 hash in DB, per-key rate limits	`dependencies.py:86-91`	Key in URL query param
Cluster Token	Cluster	`X-Cluster-Token` header, shared secret	`model_run_routes.py:13-20`	`==` not hmac

RBAC Hierarchy (`dependencies.py:185-190`)

Role	Level	Access
super_admin	4	All + admin dashboard. Always verified against DB.
org_admin	3	Org management, API keys, billing
member	2	Upload, settings, billing
viewer	1	Dashboard, reports (read-only)

4.4 Background Workers

Worker	Mechanism	Purpose
PortalWorker	SSH/SCP to cluster	Production job submission
JobWorker	Ray direct via Tailscale	Alternative path
ForecastWorker	Background thread	JAX scenario forecasting

5. Database Layer

Analyzed by: database | Full findings: findings_database.md (1400+ lines)

5.1 Dual Connection Pool

Pool	Variable	Role	RLS	Config
Superuser	`_pool`	postgres	Bypasses	min=2, max=20 `database.py:129-137`
Org-Scoped	`_org_pool`	portal_app	Enforced	min=2, max=20 `database.py:140-150`

get_org_db(org_id) sets SET LOCAL app.current_org_id per transaction (database.py:218). Multi-tenancy enforced at 3 layers: PostgreSQL RLS, application WHERE clauses, dual pool separation.

5.2 Table Inventory (33 Active + 3 Deprecated)

Subsystem	Tables	RLS Count
Auth/Users	organizations, users, api_keys, password_reset_tokens, access_logs, admin_logs	3
Fund Data	uploads, upload_funds, fund_identities, fund_identity_aliases, fund_data_versions, fund_events, fund_estimation_history	3
Model Runs	model_runs, model_run_logs, model_run_results, model_jobs, model_config_history	1
Deliverables	deliverables, posterior_results	2
Billing	product_selections, custom_invoices	2
Market/Forecast	fund_market_configs, ticker_returns_cache, fund_market_config_history, simulation_results	2
Cluster	compute_clusters, cluster_operations	0
Evergreen	evergreen_funds, evergreen_fund_members	2
Misc	organization_videos, organization_branding	1

Deprecated: subscriptions → organizations.subscription_status, funds → fund_identities, organization_fund_access → product_selections. migration 010

No stored procedures/triggers — all logic in Python (database.py ~12,400 lines). No automated migration runner — 20 SQL files applied manually.

5.3 Identity Hash System (3+3 Tiers)

Hash	Formula	Purpose	Location
`file_identity_hash`	`SHA256("file\|{org_id.lower().strip()}\|{filename.strip()}")`	File within org	`database.py:2572-2586`
`fund_identity_hash`	`SHA256("fund\|{org_id.lower().strip()}\|{filename.strip()}\|{fund_name.strip()}")`	Primary identifier: uploads→versions→posteriors→deliverables	`database.py:2589-2608`
`data_hash`	`SHA256("shape:{shape}\|cols:{sorted_cols}\|"+csv_data)`	Content deduplication	`database.py:2541-2569`

Extended: evergreen_identity_hash, eg_subfund_identity_hash, config_hash (SOC 2 tamper detection).

fund_identities registry: PK: fund_identity_hash VARCHAR(64). 6 FK constraints. Alias system for renames (max chain 5). migration 005

5.4 RLS System (18 Tables)

All use: USING (organization_id::text = current_setting('app.current_org_id', true)). Fail-safe: unset = empty = matches nothing.

Migration 003 (12): users, uploads, subscriptions, deliverables, api_keys, access_logs, organization_videos, organization_fund_access, fund_data_versions, product_selections, custom_invoices, model_jobs

Later (6): posterior_results & fund_identities (005), fund_market_configs (012), simulation_results (013), evergreen_funds & evergreen_fund_members (019)

Note: evergreen_fund_members uses subquery through evergreen_funds (different pattern).

Pre-signed URLs	Cluster→Portal→S3	X-Cluster-Token	Results pickle only (NOT HTML)

7. Infrastructure

Analyzed by: infrastructure | Full findings: findings_infrastructure.md (1000+ lines)

7.1 AWS Architecture

Service	Details	Source
Region	us-east-2 (NOT us-east-1 as aws_setup.md claims)	`config.py:68`

7.2 Deployment (deploy-to-asg.sh)

Get ASG instance IPs (:137-150)
SQL migrations on first instance via direct Aurora (:76-128)
SCP portal code (:163-195)
Rsync cluster to PhoenixNAP — IP from DB dynamically (:279-298)
Rolling restart with ALB health check (:200-260)
Bake Golden AMI, keep 3 most recent (:306-413)

No CI/CD. deploy-to-ec2.sh is legacy (still in repo).

7.3 Tailscale & PhoenixNAP

EC2 → PhoenixNAP via Tailscale WireGuard. IP: 100.75.86.48. Ray ports 6379/10001/8265 via VPN only.

PhoenixNAP: bare metal, Terraform-provisioned. 8-80 CPUs, 32-256GB RAM ($0.35-$1.09/hr).

Jobs: SCP pickle → SSH run_job.py. Systemd depends on tailscaled.

8. Admin & Client

Analyzed by: admin-client | Full findings: findings_admin_client.md

8.1 Templates (27 total)

Two bases: base.html (client, Tailwind) and admin/base.html (dark, AG Grid v31.0.1). 10 admin, 11 client, 6 standalone auth, 1 partial.

Notable: dashboard.html 351KB, cluster.html 2.1MB inline JS. cluster.html.bak 25K+ lines still present.

8.2 Admin Dashboard

9 pages, 20+ endpoints. All require super_admin. AG Grid with server-side pagination via createPaginatedGrid() (admin/base.html:72-265).

Dashboard: stats + fund selections grid
Organizations: list + detail with user role management
Jobs: model run CRUD + cancel
Cluster: Ray provisioning, worker management
Deliverables: pipeline management
Fund Timeline: re-versioning, purge
Audit Log: all actions with IP/user-agent

8.3 Excel Add-in & Stripe Billing

Excel Add-in

Office.js TaskPaneApp. sk_live_* API key in localStorage. 4 manifests (v1.1.0.0). Bidirectional sync, auto-pull posteriors, regime builder.

Stripe Billing

SOC 2 compliant (no card data stored). Single line item (20-item cap workaround). Custom cumulative invoice PDFs. Webhooks: checkout.completed, subscription.updated/deleted, invoice.paid/failed. Evergreen fund CRUD.

9. Flow: Upload → Deliverable
