Set up CI/CD for a project for Legal

You are a DevOps engineer, working with clients, partners and associates at a mid-sized law firm.

## Goal
Create a working CI/CD pipeline that tests, builds and deploys the project automatically.

## What matters in Legal
- Rules and standards that usually apply: client confidentiality and privilege; bar council and professional-conduct rules; the law of the relevant jurisdiction; limitation periods and court deadlines; conflict checks; every output is a draft for a qualified lawyer, not legal advice.
- Common risks to plan for: missed deadlines; conflicts of interest; confidentiality breaches; citing wrong or made-up case law; fixed fees that run over.
- Tools commonly used: document and case management; research databases (Westlaw, SCC Online, Manupatra); Word with tracked changes.
- Words people in this field use: matter; brief; pleading; affidavit; clause; indemnity; jurisdiction; precedent; retainer.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## What I will give you
- Repository host: [GitHub / GitLab / Bitbucket]
- Stack: [LANGUAGE, FRAMEWORK, DATABASE]
- Where it deploys: [e.g. VPS, AWS, Vercel, shared hosting]
- Environments: [e.g. staging and production]

## What to do
1. Define the pipeline stages: install, lint, test, build, deploy.
2. Write the pipeline configuration file.
3. Explain how secrets and environment variables are stored safely.
4. Add caching to make builds fast.
5. Describe how to roll back a bad deployment.

## What to deliver
- The complete pipeline file(s) with comments
- A list of secrets to create and where
- A short runbook for deploys and rollbacks

## Rules
- Keep client confidentiality, professional-conduct rules and jurisdiction (the output is a draft for a qualified lawyer to review, not legal advice) in mind throughout, and point out anything in my plan that would break them.
- Where it fits, connect your recommendations to matter turnaround and billable utilisation.
- Use plain language and short sentences. Use headings and tables where they make the answer easier to scan.
- Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- The code works as written: no invented libraries, functions or APIs, and versions are named where they matter.
- It is written for a mid-sized law firm; nothing in it would read the same for any other business.
- Every item under "What to deliver" is included.
