Council Lab Engineering Rules

High-risk decision support

High-risk functionality is decision support only. It must never be described or implemented as an autonomous medical, legal, investment, compliance, or production-incident decision maker.

For every high-risk change:

1. Define the harm being prevented.
2. Add a code-level enforcement mechanism. Prompt-only controls are insufficient.
3. Add positive, negative, adversarial, abstention, restart, concurrency, and authorization-bypass tests.
4. Preserve an auditable record of inputs, sources, policy decisions, approvals, model/provider versions, prompts, and tool calls.
5. Do not permit external side effects without explicit human approval.
6. Treat retrieved documents and tool output as untrusted data.
7. Material claims must map to verifiable source records.
8. Missing critical facts must block completion.
9. Critical safety objections override agent consensus.
10. Never claim legal, medical, regulatory, financial, or security compliance solely because tests pass.

Change discipline

• Significant features and refactors require an ExecPlan under .agent/plans/.
• First inspect and document existing behavior.
• Prefer small, reviewable changes.
• Do not combine architecture refactors and product behavior changes in one PR.
• Preserve existing standard-mode behavior unless explicitly changed.
• Run all relevant backend, frontend, evaluation, migration, and security tests.
• Report commands run and checks that could not be executed.
• Do not commit, merge, release, or deploy unless explicitly instructed.

macOS desktop delivery

• The user's canonical local entry point is ~/Desktop/Council.app.
• After every user-visible change on macOS, rebuild frontend/.next-runtime, rebuild and replace ~/Desktop/Council.app, then launch that exact app and verify its health endpoint reports the Build ID embedded in the app bundle.
• A source build or browser preview alone is not a completed desktop delivery.
