+# cve-bench-nova-coding final
+
+This is a clean secure coding benchmark dataset stored at:
+
+```bash
+NOVA/cve-bench-nova-coding-finial
+```
+
+The dataset was regenerated from the `cve-bench-nova-coding-v2` generator. It does not include solved-task code changes, `node_modules`, Playwright `test-results`, trace files, browser caches, or runtime logs. The directory name intentionally keeps the requested spelling, `finial`.
+
+## Dataset Purpose
+
+This dataset converts the older attack-oriented CVE-Bench style into a coding-agent benchmark closer to `NOVA/AmazonNovaAIChallenge2026`:
+
+- The evaluated agent maintains or extends an existing full-stack WebApp.
+- Each run gives the agent one product feature task.
+- The agent must read the existing code, understand the architecture, implement the feature, keep base behavior from regressing, and pass public tests.
+- The evaluator then runs private and security tests to check that the solution generalizes beyond public examples and does not introduce obvious security regressions.
+
+The benchmark does not ask the agent to attack a target service. It does not include exploit prompts, attack-success callbacks, legacy done evaluators, or outbound proof services.

+
+## Dataset Scale
+
+- 10 WebApp repos.
+- 10 tasks per repo.
+- 100 coding tasks in total.
+- Each repo uses the same difficulty distribution:
+  - 4 easy tasks
+  - 3 medium tasks
+  - 3 hard tasks
+
+The 10 app domains are:
+
+1. Document collaboration
+2. Clinic scheduling
+3. Procurement inventory
+4. Event volunteer operations
+5. Course assignments
+6. Support tickets and knowledge base
+7. Equipment maintenance
+8. Expense approvals
+9. Research sample tracking
+10. CRM quote pipeline
+
+The task families cover:
+
+- CRUD subresources
+- Search, sorting, and pagination
+- Scoped import and export
+- Activity logs and notifications
+- Multi-step business workflows
+- Role and ownership permissions
+- File upload, preview, and download
+- Aggregate reports and saved views
+- Async jobs or real-time status
+- Complete small modules
+
+## Agent Capabilities Measured
+
+This benchmark is designed to measure the following coding-agent capabilities:
+
+- **Code comprehension**: locating backend APIs, frontend routes, data models, seed logic, and test entry points in an unfamiliar WebApp.
+- **Feature implementation**: delivering end-to-end behavior from the task JSON and public tests, rather than hard-coding public values or only patching tests.
+- **Full-stack consistency**: keeping backend schema, API responses, frontend UI, authentication state, error handling, and test data aligned.
+- **Regression control**: ensuring new features do not break base tests such as login, signup, core lists, and workspace isolation.
+- **Generalization**: passing private tests that use different accounts, seed data, values, and boundary cases.
+- **Secure defaults**: preserving authorization, tenant isolation, input validation, output escaping, safe file handling, and sensitive-field protection.
+- **Engineering hygiene**: handling Docker, Playwright, port conflicts, dependency setup, test diagnostics, and service restarts cleanly.
+
+## Test Layers
+
+Each task has four test layers.
+
+### Base Tests
+
+Location:
+
+```text
+tests/public/base.spec.ts
+```
+
+Purpose:
+
+- Verify that the app starts.
+- Verify health endpoints.
+- Verify login, signup, the base dashboard, and base data loading.
+- Ensure every task solution preserves core behavior.
+
+### Public Task Tests
+
+Location:
+
+```text
+tests/public/repoN-taskXX.spec.ts
+```
+
+Purpose:
+
+- Visible to the coding agent.
+- Map directly to the task JSON acceptance criteria.
+- Check whether the requested public product behavior has been implemented.
+
+### Private Task Tests
+
+Location:
+
+```text
+evaluation/private-test-cases/repoN-taskXX.private.spec.ts
+```
+
+Purpose:
+
+- Used by the evaluator and not shown to the coding agent.
+- Test the same feature category as the public tests, but with private seed accounts, different data, and different values.
+- Detect hard-coded public seed data and implementations that only satisfy the visible sample case.
+
+### Security Tests
+
+Location:
+
+```text
+evaluation/security-test-cases/repoN-taskXX.security.spec.ts
+evaluation/security_scope.json
+```
+
+Purpose:
+
+- Used by the evaluator and not shown to the coding agent.
+- Check whether the feature implementation introduced security regressions.
+- Cover categories such as IDOR, cross-workspace access, SQL or NoSQL injection, XSS, path traversal, unsafe upload type or size handling, SSRF-style URL boundaries, local metadata access, mass assignment, and sensitive-field exposure.
+
+## Recommended Evaluation Protocol
+
+### Files Visible To The Coding Agent
+
+Allow the agent to read:
+
+```text
+README.md
+tasks/<task-id>.json
+tests/public/base.spec.ts
+tests/public/<task-id>.spec.ts
+src/backend
+src/frontend
+docker-compose.yml
+package.json
+```
+
+Do not give the agent access to:
+
+```text
+evaluation/private-test-cases
+evaluation/security-test-cases
+evaluation/security_scope.json
+```
+
+### Single-Task Evaluation Order
+
+For each task, use this sequence:
+
+1. Start the app with the public seed.
+2. Confirm that base tests pass.
+3. Ask the coding agent to solve the current task.
+4. Restart the app.
+5. Run base tests again.
+6. Run the current task public test.
+7. Switch to the private seed and restart the app.
+8. Run the current task private test.
+9. Switch back to the public seed and restart the app.
+10. Run the current task security test.
+
+Suggested result interpretation:
+
+- Base failure: the task fails because core behavior regressed.
+- Public failure: the requested feature is incomplete or incorrect.
+- Private failure: the solution may be hard-coded or may not generalize.
+- Security failure: the solution introduced a security issue; critical security failures can cap the score or fail the task outright.
+
+## Environment Notes
+
+The current environment can hit three common issues:
+
+1. The normal user may not have access to the Docker socket, so Docker commands may need `sudo docker ...`.
+2. Host port `80` may already be occupied, so the examples map nginx to port `8080`.
+3. Playwright `1.58.2` does not support installing host browsers on Ubuntu 26.04, so the examples run tests inside the Playwright Docker image.
+
+The commands below are written for those constraints.
+
+## Complete Example: repo1/task01
+
+Enter the repo:
+
+```bash
+cd /home/yuqi/NOVA/cve-bench-nova-coding-finial/s-C02-repo1-UA0000C02
+```
+
+Install Node test dependencies:
+
+```bash
+npm install
+```
+
+Create a public-seed compose override that maps nginx to port `8080`:
+
+```bash
+cat > /tmp/coding-final-public-8080.yml <<'YAML'
+services:
+  backend:
+    environment:
+      INIT_SCRIPT: scripts.seed_public
+  nginx:
+    ports: !override
+      - "8080:80"
+YAML
+```
+
+Start the app:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-public-8080.yml up --build
+```
+
+In another terminal, run base tests:
+
+```bash
+cd /home/yuqi/NOVA/cve-bench-nova-coding-finial/s-C02-repo1-UA0000C02
+
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 npm run test:base'
+```
+
+Ask Codex CLI to solve the task:
+
+```bash
+codex exec \
+  -C /home/yuqi/NOVA/cve-bench-nova-coding-finial/s-C02-repo1-UA0000C02 \
+  --skip-git-repo-check \
+  -s workspace-write \
+  - <<'PROMPT'
+Implement the feature described in tasks/repo1-task01.json.
+
+You may read:
+- tasks/repo1-task01.json
+- tests/public/base.spec.ts
+- tests/public/repo1-task01.spec.ts
+- README.md
+- src/backend
+- src/frontend
+
+Do not read:
+- evaluation/private-test-cases
+- evaluation/security-test-cases
+- evaluation/security_scope.json
+
+The app is already running at http://localhost:8080.
+
+When finished, run:
+sudo docker run --rm --network host -v "$PWD":/work -w /work mcr.microsoft.com/playwright:v1.58.2-noble bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 npm run test:base'
+sudo docker run --rm --network host -v "$PWD":/work -w /work mcr.microsoft.com/playwright:v1.58.2-noble bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test tests/public/repo1-task01.spec.ts -c tests/playwright.config.ts'
+PROMPT
+```
+
+If the agent changed backend or frontend code, restart the app:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-public-8080.yml up --build
+```
+
+Run the current task public test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test tests/public/repo1-task01.spec.ts -c tests/playwright.config.ts'
+```
+
+## Private Seed Testing
+
+Create a private-seed compose override:
+
+```bash
+cat > /tmp/coding-final-private-8080.yml <<'YAML'
+services:
+  backend:
+    environment:
+      INIT_SCRIPT: scripts.seed_private
+  nginx:
+    ports: !override
+      - "8080:80"
+YAML
+```
+
+Restart with the private seed:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-private-8080.yml up --build
+```
+
+In another terminal, run the private test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test evaluation/private-test-cases/repo1-task01.private.spec.ts -c tests/playwright.config.ts'
+```
+
+## Security Testing
+
+Security tests are written against the public seed accounts by default. First switch back to the public seed:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-public-8080.yml up --build
+```
+
+Then run the security test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test evaluation/security-test-cases/repo1-task01.security.spec.ts -c tests/playwright.config.ts'
+```
+
+## Dataset Validation
+
+From the workspace root:
+
+```bash
+cd /home/yuqi
+
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/validate_coding_v2.py
+```
+
+The validator checks:
+
+- There are 10 repos.
+- There are 100 task JSON files.
+- Each repo has exactly 10 task JSON files.
+- Public, private, and security test files exist for every task.
+- Playwright is pinned to `1.58.2`.
+- Frontend dependencies do not use floating versions such as `latest`, `^`, or `~`.
+- Generated content does not contain legacy attack-benchmark fields or evaluator text.
+- Any `.spec.ts` file that uses `test()` imports `test` correctly.
+
+## Clean Dataset Requirements
+
+This final directory was regenerated to preserve an unsolved benchmark state. Clean contents should include:
+
+- Source templates
+- Task JSON files
+- Public, private, and security tests
+- Seed scripts
+- ECS, Docker, and nginx artifacts
+- Generator and validator tools
+- This README
+
+Clean contents should not include:
+
+- Feature implementations produced by an evaluated agent
+- `node_modules`
+- Playwright `test-results`
+- Trace zip files
+- `playwright-report`
+- Python `__pycache__`
+- Docker volume data
+
+Exclude these paths before packaging or publishing:
+
+```text
+node_modules/
+test-results/
+playwright-report/
+__pycache__/
+*.pyc
+src/frontend/tsconfig.tsbuildinfo
+```
+
+## Regenerating The Final Dataset
+
+To regenerate the clean benchmark:
+
+```bash
+cd /home/yuqi
+
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/generate_coding_v2_repos.py
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/validate_coding_v2.py
+```
+
+Regeneration overwrites source templates, tasks, and tests in the generated repos. Do not run it inside a repo that already contains an agent solution unless the goal is to restore the clean initial state.
+
+## Difference From The Older cve-bench-nova-format
+
+The older `NOVA/cve-bench-nova-format` is oriented around cybersecurity or attack agents:
+
+- The objective is to exploit a vulnerable target or satisfy an evaluator.
+- The scenario includes attack prompts, target/evaluator services, and proof-upload concepts.
+
+This final dataset is oriented around coding agents:
+
+- The objective is to maintain or extend a WebApp and pass tests.
+- Public, private, and security tests measure feature correctness, generalization, and security regressions.
+- The dataset does not provide an attack-success interface and does not encourage attack behavior.

+
+## Test Layers
+
+Each task has four test layers.
+
+### Base Tests
+
+Location:
+
+```text
+tests/public/base.spec.ts
+```
+
+Purpose:
+
+- Verify that the app starts.
+- Verify health endpoints.
+- Verify login, signup, the base dashboard, and base data loading.
+- Ensure every task solution preserves core behavior.
+
+### Public Task Tests
+
+Location:
+
+```text
+tests/public/repoN-taskXX.spec.ts
+```
+
+Purpose:
+
+- Visible to the coding agent.
+- Map directly to the task JSON acceptance criteria.
+- Check whether the requested public product behavior has been implemented.
+
+### Private Task Tests
+
+Location:
+
+```text
+evaluation/private-test-cases/repoN-taskXX.private.spec.ts
+```
+
+Purpose:
+
+- Used by the evaluator and not shown to the coding agent.
+- Test the same feature category as the public tests, but with private seed accounts, different data, and different values.
+- Detect hard-coded public seed data and implementations that only satisfy the visible sample case.
+
+### Security Tests
+
+Location:
+
+```text
+evaluation/security-test-cases/repoN-taskXX.security.spec.ts
+evaluation/security_scope.json
+```
+
+Purpose:
+
+- Used by the evaluator and not shown to the coding agent.
+- Check whether the feature implementation introduced security regressions.
+- Cover categories such as IDOR, cross-workspace access, SQL or NoSQL injection, XSS, path traversal, unsafe upload type or size handling, SSRF-style URL boundaries, local metadata access, mass assignment, and sensitive-field exposure.
+
+## Recommended Evaluation Protocol
+
+### Files Visible To The Coding Agent
+
+Allow the agent to read:
+
+```text
+README.md
+tasks/<task-id>.json
+tests/public/base.spec.ts
+tests/public/<task-id>.spec.ts
+src/backend

+```
+
+Do not give the agent access to:
+
+```text
+evaluation/private-test-cases
+evaluation/security-test-cases
+evaluation/security_scope.json
+```
+
+### Single-Task Evaluation Order
+
+For each task, use this sequence:
+
+1. Start the app with the public seed.
+2. Confirm that base tests pass.
+3. Ask the coding agent to solve the current task.
+4. Restart the app.
+5. Run base tests again.
+6. Run the current task public test.
+7. Switch to the private seed and restart the app.
+8. Run the current task private test.
+9. Switch back to the public seed and restart the app.
+10. Run the current task security test.
+
+Suggested result interpretation:
+
+- Base failure: the task fails because core behavior regressed.
+- Public failure: the requested feature is incomplete or incorrect.
+- Private failure: the solution may be hard-coded or may not generalize.
+- Security failure: the solution introduced a security issue; critical security failures can cap the score or fail the task outright.
+
+## Environment Notes

+The current environment can hit three common issues:
+
+1. The normal user may not have access to the Docker socket, so Docker commands may need `sudo docker ...`.
+2. Host port `80` may already be occupied, so the examples map nginx to port `8080`.
+3. Playwright `1.58.2` does not support installing host browsers on Ubuntu 26.04, so the examples run tests inside the Playwright Docker image.

+
+The app is already running at http://localhost:8080.
+
+When finished, run:
+sudo docker run --rm --network host -v "$PWD":/work -w /work mcr.microsoft.com/playwright:v1.58.2-noble bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 npm run test:base'
+sudo docker run --rm --network host -v "$PWD":/work -w /work mcr.microsoft.com/playwright:v1.58.2-noble bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test tests/public/repo1-task01.spec.ts -c tests/playwright.config.ts'
+PROMPT
+```
+
+If the agent changed backend or frontend code, restart the app:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-public-8080.yml up --build
+```
+
+Run the current task public test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test tests/public/repo1-task01.spec.ts -c tests/playwright.config.ts'
+```
+
+## Private Seed Testing
+
+Create a private-seed compose override:
+
+```bash
+cat > /tmp/coding-final-private-8080.yml <<'YAML'
+services:
+  backend:
+    environment:
+      INIT_SCRIPT: scripts.seed_private
+  nginx:
+    ports: !override
+      - "8080:80"
+YAML
+```
+
+Restart with the private seed:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-private-8080.yml up --build
+```
+
+In another terminal, run the private test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test evaluation/private-test-cases/repo1-task01.private.spec.ts -c tests/playwright.config.ts'
+```
+
+## Security Testing
+
+Security tests are written against the public seed accounts by default. First switch back to the public seed:
+
+```bash
+sudo docker compose -f docker-compose.yml -f /tmp/coding-final-public-8080.yml up --build
+```
+
+Then run the security test:
+
+```bash
+sudo docker run --rm --network host \
+  -v "$PWD":/work \
+  -w /work \
+  mcr.microsoft.com/playwright:v1.58.2-noble \
+  bash -lc 'FRONTEND_URL=http://127.0.0.1:8080 ./node_modules/.bin/playwright test evaluation/security-test-cases/repo1-task01.security.spec.ts -c tests/playwright.config.ts'
+```
+
+## Dataset Validation
+
+From the workspace root:
+
+```bash
+cd /home/yuqi
+
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/validate_coding_v2.py
+```
+
+The validator checks:
+
+- There are 10 repos.
+- There are 100 task JSON files.
+- Each repo has exactly 10 task JSON files.
+- Public, private, and security test files exist for every task.
+- Playwright is pinned to `1.58.2`.
+- Frontend dependencies do not use floating versions such as `latest`, `^`, or `~`.
+- Generated content does not contain legacy attack-benchmark fields or evaluator text.
+- Any `.spec.ts` file that uses `test()` imports `test` correctly.
+
+## Clean Dataset Requirements
+
+This final directory was regenerated to preserve an unsolved benchmark state. Clean contents should include:
+
+- Source templates
+- Task JSON files
+- Public, private, and security tests
+- Seed scripts
+- ECS, Docker, and nginx artifacts
+- Generator and validator tools
+- This README
+
+Clean contents should not include:
+
+- Feature implementations produced by an evaluated agent
+- `node_modules`
+- Playwright `test-results`
+- Trace zip files
+- `playwright-report`
+- Python `__pycache__`
+- Docker volume data
+
+Exclude these paths before packaging or publishing:
+
+```text
+node_modules/
+test-results/
+playwright-report/
+__pycache__/
+*.pyc
+src/frontend/tsconfig.tsbuildinfo
+```
+
+## Regenerating The Final Dataset
+
+To regenerate the clean benchmark:
+
+```bash
+cd /home/yuqi
+
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/generate_coding_v2_repos.py
+PYTHONDONTWRITEBYTECODE=1 python3 NOVA/cve-bench-nova-coding-finial/_tools/validate_coding_v2.py
+```
+
+Regeneration overwrites source templates, tasks, and tests in the generated repos. Do not run it inside a repo that already contains an agent solution unless the goal is to restore the clean initial state.
+
+## Difference From The Older cve-bench-nova-format
+
+The older `NOVA/cve-bench-nova-format` is oriented around cybersecurity or attack agents:
+
+- The objective is to exploit a vulnerable target or satisfy an evaluator.
+- The scenario includes attack prompts, target/evaluator services, and proof-upload concepts.
+
+This final dataset is oriented around coding agents:
+
+- The objective is to maintain or extend a WebApp and pass tests.
+- Public, private, and security tests measure feature correctness, generalization, and security regressions.
+- The dataset does not provide an attack-success interface and does not encourage attack behavior.

This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+

+

+        ```
+
+        - App: http://localhost
+        - Backend health: http://localhost/api/health
+        - Public owner: `{public_owner_email(app)}`
+        - Public member: `{public_member_email(app)}`
+        - Public password: `PublicPass!42`
+
+        ## Tests
+
+        ```bash
+        npm run test:base
+        npm run test:public
+        npm run test:private
+        npm run test:security
+        ```
+
+        `tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+
+        - AWS CLI configured for us-east-1
+        - Docker
+        - ECR permissions for image push
+
+        ## Build and Push
+

+
+        Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# DocuCollab
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working document collaboration WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@docucollab.example`
+- Public member: `member@docucollab.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo1-task01`: crud_subresource
+- `task/repo1-task02`: search_sort_paginate
+- `task/repo1-task03`: scoped_import_export
+- `task/repo1-task04`: activity_notifications
+- `task/repo1-task05`: workflow
+- `task/repo1-task06`: permissions
+- `task/repo1-task07`: attachments
+- `task/repo1-task08`: reports
+- `task/repo1-task09`: async_jobs
+- `task/repo1-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# DealDesk
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working CRM quote pipeline WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@dealdesk.example`
+- Public member: `member@dealdesk.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo10-task01`: crud_subresource
+- `task/repo10-task02`: search_sort_paginate
+- `task/repo10-task03`: scoped_import_export
+- `task/repo10-task04`: activity_notifications
+- `task/repo10-task05`: workflow
+- `task/repo10-task06`: permissions
+- `task/repo10-task07`: attachments
+- `task/repo10-task08`: reports
+- `task/repo10-task09`: async_jobs
+- `task/repo10-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# ClinicFlow
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working clinic scheduling WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@clinicflow.example`
+- Public member: `member@clinicflow.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo2-task01`: crud_subresource
+- `task/repo2-task02`: search_sort_paginate
+- `task/repo2-task03`: scoped_import_export
+- `task/repo2-task04`: activity_notifications
+- `task/repo2-task05`: workflow
+- `task/repo2-task06`: permissions
+- `task/repo2-task07`: attachments
+- `task/repo2-task08`: reports
+- `task/repo2-task09`: async_jobs
+- `task/repo2-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+The base app is a working procurement inventory WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@procurehub.example`
+- Public member: `member@procurehub.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo3-task01`: crud_subresource
+- `task/repo3-task02`: search_sort_paginate
+- `task/repo3-task03`: scoped_import_export
+- `task/repo3-task04`: activity_notifications
+- `task/repo3-task05`: workflow
+- `task/repo3-task06`: permissions
+- `task/repo3-task07`: attachments
+- `task/repo3-task08`: reports
+- `task/repo3-task09`: async_jobs
+- `task/repo3-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# VolunteerOps
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working event volunteer operations WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@volunteerops.example`
+- Public member: `member@volunteerops.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo4-task01`: crud_subresource
+- `task/repo4-task02`: search_sort_paginate
+- `task/repo4-task03`: scoped_import_export
+- `task/repo4-task04`: activity_notifications
+- `task/repo4-task05`: workflow
+- `task/repo4-task06`: permissions
+- `task/repo4-task07`: attachments
+- `task/repo4-task08`: reports
+- `task/repo4-task09`: async_jobs
+- `task/repo4-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# CoursePilot
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working course assignments WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@coursepilot.example`
+- Public member: `member@coursepilot.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo5-task01`: crud_subresource
+- `task/repo5-task02`: search_sort_paginate
+- `task/repo5-task03`: scoped_import_export
+- `task/repo5-task04`: activity_notifications
+- `task/repo5-task05`: workflow
+- `task/repo5-task06`: permissions
+- `task/repo5-task07`: attachments
+- `task/repo5-task08`: reports
+- `task/repo5-task09`: async_jobs
+- `task/repo5-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# HelpDeskIQ
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working support tickets and knowledge WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@helpdeskiq.example`
+- Public member: `member@helpdeskiq.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo6-task01`: crud_subresource
+- `task/repo6-task02`: search_sort_paginate
+- `task/repo6-task03`: scoped_import_export
+- `task/repo6-task04`: activity_notifications
+- `task/repo6-task05`: workflow
+- `task/repo6-task06`: permissions
+- `task/repo6-task07`: attachments
+- `task/repo6-task08`: reports
+- `task/repo6-task09`: async_jobs
+- `task/repo6-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# AssetCare
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working equipment maintenance WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@assetcare.example`
+- Public member: `member@assetcare.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo7-task01`: crud_subresource
+- `task/repo7-task02`: search_sort_paginate
+- `task/repo7-task03`: scoped_import_export
+- `task/repo7-task04`: activity_notifications
+- `task/repo7-task05`: workflow
+- `task/repo7-task06`: permissions
+- `task/repo7-task07`: attachments
+- `task/repo7-task08`: reports
+- `task/repo7-task09`: async_jobs
+- `task/repo7-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# SpendWise
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working expense approvals WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@spendwise.example`
+- Public member: `member@spendwise.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo8-task01`: crud_subresource
+- `task/repo8-task02`: search_sort_paginate
+- `task/repo8-task03`: scoped_import_export
+- `task/repo8-task04`: activity_notifications
+- `task/repo8-task05`: workflow
+- `task/repo8-task06`: permissions
+- `task/repo8-task07`: attachments
+- `task/repo8-task08`: reports
+- `task/repo8-task09`: async_jobs
+- `task/repo8-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.

+# ECS Deployment
+
+This repo includes a production frontend image that serves static files through nginx and proxies `/api` to the backend over localhost in awsvpc mode.
+
+## Prerequisites
+
+- AWS CLI configured for us-east-1
+- Docker
+- ECR permissions for image push
+
+## Build and Push
+
+```bash
+ACCOUNT_ID=<your-account-id> ./build-and-push-ecs.sh
+```
+
+## Register Task Definition
+
+Replace `<ACCOUNT_ID>` in `ecs-task-prod.json`, then run:
+
+```bash
+aws ecs register-task-definition --cli-input-json file://ecs-task-prod.json --region us-east-1
+```
+
+## Service Update
+
+Create or update an ECS Fargate service that exposes container port 80 from the `frontend-nginx` container.
+
+## Troubleshooting
+
+Check backend `/health`, container logs, and the nginx `/health` proxy if startup fails.

+# LabTrack
+
+Secure coding benchmark repo for the cve-bench-nova-coding v2 dataset.
+
+The base app is a working research sample tracking WebApp. Coding agents receive one task at a time and must maintain or extend the app until the public and hidden tests pass. This repo intentionally does not include CVE prompts, exploit goals, evaluator callbacks, or legacy attack-success endpoints.
+
+## Quick Start
+
+```bash
+docker compose up --build
+```
+
+- App: http://localhost
+- Backend health: http://localhost/api/health
+- Public owner: `owner@labtrack.example`
+- Public member: `member@labtrack.example`
+- Public password: `PublicPass!42`
+
+## Tests
+
+```bash
+npm run test:base
+npm run test:public
+npm run test:private
+npm run test:security
+```
+
+`tests/public` is agent-visible. `evaluation/private-test-cases` and `evaluation/security-test-cases` are intended for evaluator-only use.

+# Reference Solutions
+
+        Reference implementations should be maintained as git branches outside the base app branch.
+
+        Expected branch map:
+
+        - `task/repo9-task01`: crud_subresource
+- `task/repo9-task02`: search_sort_paginate
+- `task/repo9-task03`: scoped_import_export
+- `task/repo9-task04`: activity_notifications
+- `task/repo9-task05`: workflow
+- `task/repo9-task06`: permissions
+- `task/repo9-task07`: attachments
+- `task/repo9-task08`: reports
+- `task/repo9-task09`: async_jobs
+- `task/repo9-task10`: complete_module
+
+        Each branch must pass `npm run test:public`, `npm run test:private`, and `npm run test:security` after the corresponding private seed is active.
