+<!-- Link any related issues: Closes #N, Relates to #N -->
+
+## Type of change

+- [ ] Bug fix
+- [ ] New feature / enhancement
+- [ ] Documentation
+- [ ] CI / tooling
+- [ ] Security fix
+- [ ] Refactor (no functional change)

+
+## Verification checklist
+
+> Fill in **all three sections**. Omitting a section or leaving placeholders
+> will block review. Claiming something was verified when it was not is worse
+> than marking it as not verified — the latter is acceptable, the former is not.
+
+### ✅ Verified locally
+
+<!-- List what you ran and the result. Example:
+- `dotnet build` — passed
+- `dotnet test` on Linux — all tests green
+- `shellcheck` on changed deploy scripts — no errors
+- Smoke-tested bootstrap install on Ubuntu 24.04 VM
+-->
+
+### ✅ Verified in CI
+
+<!-- Paste links to workflow runs for this branch, or state "CI not yet run". -->
+
+### ❌ Not verified / out of scope
+
+<!-- Explicitly list what was NOT verified and why. Examples:
+- Physical three-server acceptance test — SSH and topology parameters not available.
+- Windows MSIX install on clean machine — no Windows test environment.
+- arm64 boot — no arm64 runner locally.
+
+This section must not be left empty. If everything is verified, write "None." -->

+# Contributing to Server Monitor Manager
+
+Thank you for your interest in contributing. This document describes how to
+build the project, run tests, and submit changes.
+
+## Building
+
+### Prerequisites
+
+- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
+- A Linux host or WSL for server-side components (see [Testing](#testing))
+- `shellcheck` for shell script linting
+
+### Build
+
+```bash
+dotnet build ServerMonitorManager.slnx --configuration Release
+```
+
+### Publish (Linux binaries)
+
+```bash
+dotnet publish src/ServerMonitorManager.Agent/ServerMonitorManager.Agent.csproj \
+  --configuration Release --runtime linux-x64 --self-contained true \
+  -p:PublishSingleFile=true -p:PublishTrimmed=true -o out/agent
+
+dotnet publish src/ServerMonitorManager.Control/ServerMonitorManager.Control.csproj \
+  --configuration Release --runtime linux-x64 --self-contained true \
+  -p:PublishSingleFile=true -p:PublishTrimmed=true -o out/control
+```
+
+## Testing
+
+### Unit and integration tests
+
+```bash
+dotnet test tests/ServerMonitorManager.Control.Tests/ServerMonitorManager.Control.Tests.csproj \
+  --configuration Release
+```
+
+> **Important:** The Control test suite must be run on **Linux**. A subset of
+> tests is gated with `[SupportedOSPlatform("linux")]` / `OperatingSystem.IsLinux()`
+> and will be **silently skipped on Windows**. CI always runs these on Ubuntu;
+> do not interpret a green local run on Windows as full test coverage.
+
+### Bootstrap contract tests
+
+```bash
+bash tests/bootstrap/test-bootstrap-contract.sh
+bash tests/bootstrap/test-enrollment-token-argv.sh
+```
+
+### Shell script linting
+
+```bash
+shellcheck --severity=error deploy/ochenstarik-server-monitor-manager.sh
+shellcheck --severity=error deploy/ochenstarik-smm-policy-apply
+shellcheck --severity=error deploy/ochenstarik-smm-emergency
+```
+
+### Windows Desktop tests
+
+```powershell
+./tests/windows/Test-DesktopContracts.ps1
+dotnet test tests/ServerMonitorManager.Desktop.Security.Tests/ServerMonitorManager.Desktop.Security.Tests.csproj --configuration Release
+```
+
+## Code Style
+
+Verify formatting before committing:
+
+```bash
+dotnet format ServerMonitorManager.slnx --verify-no-changes
+```
+
+## Submitting Changes
+
+**One PR — one topic.** Do not bundle unrelated changes in a single pull
+request. Small, focused PRs are reviewed faster and are easier to revert if
+needed.
+
+1. Fork the repository and create a branch from `main`.
+2. Make your changes, keeping the scope focused.
+3. Run all relevant tests locally (see above).
+4. Open a pull request using the PR template — fill in **all sections**,
+   including what was *not* tested and why.
+
+## What Not to Change

+
+## Supported Versions
+
+Server Monitor Manager is currently in alpha. Only the latest pre-release is
+supported with security fixes:
+
+| Version | Supported |
+|---|---|
+| latest alpha (v0.1.0-alpha.6) | ✅ |
+| earlier alphas | ❌ |
+
+## Reporting a Vulnerability
+
+**Do not open a public GitHub issue for security vulnerabilities.**
+
+Report vulnerabilities privately via GitHub's built-in mechanism:
+[Security → Report a vulnerability](https://github.com/ochenstarik-ui/server-monitor-manager/security/advisories/new)
+
+This opens a private advisory draft visible only to repository maintainers.
+
+### What to include
+
+- A description of the vulnerability and its potential impact.
+- Steps to reproduce or a proof-of-concept (even a minimal one).
+- The version or commit you tested against.
+- Your GitHub handle or email if you want to be credited.
+
+### Response timeline
+
+| Milestone | Target |
+|---|---|
+| Initial acknowledgement | Within **72 hours** of receipt |
+| Triage and severity assessment | Within **7 days** |
+| Patch or mitigation plan | Communicated within **14 days** |
+| Public disclosure | Coordinated with the reporter |
+
+## Threat Model and Scope
+
+Server Monitor Manager installs binaries that run as **root** on servers and
+manages firewall rules. The following are considered **in-scope
+vulnerabilities**:
+
+- **Role separation bypass** — an Agent being able to perform Control
+  operations or vice versa without explicit provisioning.
+- **Unauthorized root execution** — obtaining root-level code execution
+  outside of the typed provisioning flow (`install-control`,
+  `install-agent`).
+- **Private key or enrollment token leakage** — exposure of mTLS private
+  keys, CA keys, or enrollment tokens to unprivileged processes or logs.
+- **Kill switch bypass** — circumventing the emergency kill switch
+  (`ochenstarik-smm-emergency`) or the disabled-link enforcement.
+- **Supply chain / artifact substitution** — an attacker substituting
+  release artifacts or bootstrap scripts to deliver malicious binaries.
+
+## Known Limitations (Not Vulnerabilities)
+
+The following are **documented alpha limitations** and will not be treated as
+security vulnerabilities until addressed in the roadmap:
+
+- **Release manifest is not cryptographically signed.** The bootstrap manifest
+  (`server-monitor-manager-bootstrap-manifest.json`) includes a SHA-256
+  checksum but the manifest itself carries no signature. Tracked in
+  [`docs/roadmap.md`](docs/roadmap.md).
+- **Windows MSIX is not trusted-signed.** The Windows installer is signed with
+  a test or self-signed certificate in CI. Trust requires a commercial code
+  signing certificate. Tracked in [`docs/roadmap.md`](docs/roadmap.md).
+
+Both items are openly acknowledged limitations of the alpha stage. Reports
+about these specific issues will be noted but not assigned a CVE or priority
+fix until the roadmap items are scheduled.
