-# Governance
-
-`outpost` is a small, single-maintainer homelab project. Governance is
-deliberately lightweight, but two things are **policy**, not just habit.
-
-## Roles
-
-- **Maintainer** — sole decision-maker; see [MAINTAINERS.md](MAINTAINERS.md).
-- **Contributors** — anyone opening issues/PRs. Welcome, but changes to the
- surfaces below require explicit maintainer sign-off.
-
-## Decision process
-
-Day-to-day: lazy consensus on PRs. The maintainer merges. Linear history;
-squash or rebase only (no merge commits).
-
-## Policy 1 — base images are maintainer-gated
-
-The pinned container base lives in [`/images.lock`](../images.lock) as a
-**multi-arch manifest-list digest** (the reproducible base the appliance boots
-from). It is changed **only** by a deliberate maintainer action:
-
-- Detection is automated and **report-only**: `sh bin/bump.sh --check`
- (exit `10` = an upgrade is available) and `sh bin/bump.sh --verify`
- (assert the current pin still matches source — supply-chain drift check).
-- Application is a separate, explicit choice: `sh bin/bump.sh --apply`, which
- re-resolves the digest from source and repins **only after the maintainer
- confirms**. The resulting `images.lock` change is reviewed and committed like
- any other diff.
-
-A weekly **canary** (`bin/canary.sh`, installed as a crond/systemd job on owned
-compute — never GitHub Actions) runs exactly those report-only modes and pings
-the maintainer when there is something to decide. It cannot apply anything.
-
-Rationale: detection without auto-application. The tool never silently moves the
-base; a human makes the upgrade call. Never pin or boot a floating tag —
-`bin/up.sh` refuses to launch anything not pinned to a `@sha256:` digest.
-
-## Policy 2 — surface-changing edits need review
-
-Changes to `host/nftables.nft`, `host/cups/`, or anything that alters the box's
-exposed network surface get extra scrutiny (this is, after all, a piece of
-network infrastructure). Default-deny stays default-deny.
-
-## Security
-
-Report security issues per [SECURITY.md](SECURITY.md) (or the org-level policy
-in `hyperpolymath/.github`) — not in public issues.
-
-## Changing this document
-
-Amendments are a maintainer decision, recorded in git history.

+# Code of Conduct
+
+
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in Squisher Corpus a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, colour, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+We recognise that a thriving open source community requires **psychological safety** — an environment where people can contribute, ask questions, make mistakes, and learn without fear of ridicule or retaliation.
+
+---
+
+## Our Standards
+
+### Expected Behaviour
+
+The following behaviours contribute to a positive environment:
+
+**Communication**
+- Using welcoming and inclusive language
+- Being respectful of differing viewpoints and experiences
+- Giving and gracefully accepting constructive feedback
+- Assuming good intent while addressing impact
+- Communicating clearly and patiently, especially with newcomers
+
+**Collaboration**
+- Focusing on what is best for the community
+- Showing empathy and kindness toward other community members
+- Being collaborative rather than competitive
+- Mentoring and supporting less experienced contributors
+- Celebrating others' contributions and successes
+
+**Professionalism**
+- Accepting responsibility and apologising to those affected by our mistakes
+- Learning from the experience and avoiding repetition
+- Respecting others' time and attention
+- Staying on topic in project spaces
+- Following project guidelines and conventions
+
+**Accessibility**
+- Using plain language and avoiding unnecessary jargon
+- Providing alt text for images and transcripts for audio/video
+- Being patient with those using assistive technologies
+- Accommodating different communication styles and needs
+- Recognising that not everyone communicates the same way
+
+### Unacceptable Behaviour
+
+The following behaviours are considered harassment and are unacceptable:
+
+**Harassment**
+- The use of sexualised language or imagery, and sexual attention or advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Deliberate intimidation, stalking, or following (online or in-person)
+- Unwelcome physical contact or simulated physical contact (e.g., emoji)
+- Sustained disruption of talks, events, or online discussions
+
+**Discrimination**
+- Discriminatory jokes and language
+- Posting or threatening to post others' personally identifying information ("doxing")
+- Advocating for, or encouraging, any of the above behaviour
+- Microaggressions — subtle, often unintentional, discriminatory comments or actions
+
+**Professional Misconduct**
+- Publishing others' private information without explicit permission
+- Misrepresenting affiliation or contributions
+- Plagiarism or claiming credit for others' work
+- Retaliating against anyone who reports a Code of Conduct violation
+- Other conduct which could reasonably be considered inappropriate in a professional setting
+
+### Grey Areas
+
+Some situations require judgement. When uncertain:
+
+- **Intent vs Impact**: Good intentions do not excuse harmful impact. Focus on making things right.
+- **Power Dynamics**: Those with more power (maintainers, employers, experienced contributors) must be especially mindful of their impact.
+- **Cultural Differences**: What's acceptable varies by culture. When in doubt, err on the side of caution and ask.
+- **Humour**: Jokes at others' expense are rarely funny to everyone. Punch up, not down.
+
+---
+
+## Scope
+
+This Code of Conduct applies within all community spaces, including:
+
+**Online Spaces**
+- Repository discussions, issues, and pull/merge requests
+- Project chat channels (Matrix, Discord, Slack, IRC)
+- Mailing lists and forums
+- Social media when representing the project
+- Video calls and virtual meetings
+
+**In-Person Spaces**
+- Conferences, meetups, and events
+- Workshops and training sessions
+- Any gathering where you represent the project
+
+**Representation**
+This Code of Conduct also applies when an individual is officially representing the community in public spaces. Examples include:
+
+- Using an official project email address
+- Posting via an official social media account
+- Acting as an appointed representative at an event
+- Speaking on behalf of the project
+
+---
+
+## Enforcement
+
+### Reporting

+
+### Conflicts of Interest
+
+If a maintainers member is involved in an incident:
+
+- They will recuse themselves from the process
+- Another maintainer or external party will handle the report
+- We will disclose any potential conflicts
+
+---
+
+## Enforcement Guidelines
+
+The maintainers will follow these guidelines in determining consequences:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behaviour deemed unprofessional or unwelcome.
+
+**Consequence**: A private, written warning providing clarity around the nature of the violation and an explanation of why the behaviour was inappropriate. A public apology may be requested.
+
+**Duration**: Immediate
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behaviour. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+**Duration**: 1-4 weeks
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behaviour.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+**Duration**: 1-6 months
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behaviour, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.
+
+**Duration**: Permanent (with appeal rights after 12 months)
+
+### Enforcement Across Perimeters
+
+For contributors with elevated access (Perimeter 2 or 1):
+
+| Level | Additional Consequence |
+|-------|----------------------|
+| Correction | Noted in contributor record |
+| Warning | Access privileges may be temporarily reduced |
+| Temporary Ban | Access reduced to Perimeter 3 for ban duration |
+| Permanent Ban | All access revoked |
+
+---
+
+## Appeals

+1. **Wait 7 days** after the decision (cooling-off period)
+2. **Email** j.d.a.jewell@open.ac.uk with subject line "Appeal: [Original Report ID]"
+3. **Explain** why you believe the decision should be reconsidered
+4. **Provide** any new information not previously available
+
+**Appeals Process**
+
+- Appeals are reviewed by a different maintainers member than the original
+- You will receive a response within 14 days
+- The appeals decision is final
+- You may only appeal once per incident
+
+**Grounds for Appeal**
+
+- Procedural errors in the original investigation
+- New evidence not previously available
+- Disproportionate response to the violation
+- Misunderstanding of facts

+
+## Reporting a Vulnerability
+
+### Preferred Method: GitHub Security Advisories
+
+The preferred method for reporting security vulnerabilities is through GitHub's Security Advisory feature:
+
+1. Navigate to [Report a Vulnerability](https://github.com/hyperpolymath/network-outpost/security/advisories/new)
+2. Click **"Report a vulnerability"**
+3. Complete the form with as much detail as possible
+4. Submit — we'll receive a private notification
+
+This method ensures:
+
+- End-to-end encryption of your report
+- Private discussion space for collaboration
+- Coordinated disclosure tooling
+- Automatic credit when the advisory is published
+
+### Alternative: Encrypted Email
+
+If you cannot use GitHub Security Advisories, you may email us directly:
+
+| | |
+|---|---|
+| **Email** | j.d.a.jewell@open.ac.uk |
+| **PGP Key** | [Download Public Key](https://github.com/hyperpolymath.gpg) |
+| **Fingerprint** | `TBD` |
+
+```bash
+# Import our PGP key
+curl -sSL https://github.com/hyperpolymath.gpg | gpg --import
+
+# Verify fingerprint
+gpg --fingerprint j.d.a.jewell@open.ac.uk
+
+# Encrypt your report
+gpg --armor --encrypt --recipient j.d.a.jewell@open.ac.uk report.txt
+```
+
+> **⚠️ Important:** Do not report security vulnerabilities through public GitHub issues, pull requests, discussions, or social media.
+
+---
+
+## What to Include

+
+## Response Timeline
+
+We commit to the following response times:
+
+| Stage | Timeframe | Description |
+|-------|-----------|-------------|
+| **Initial Response** | 48 hours | We acknowledge receipt and confirm we're investigating |
+| **Triage** | 7 days | We assess severity, confirm the vulnerability, and estimate timeline |
+| **Status Update** | Every 7 days | Regular updates on remediation progress |
+| **Resolution** | 90 days | Target for fix development and release (complex issues may take longer) |
+| **Disclosure** | 90 days | Public disclosure after fix is available (coordinated with you) |
+
+> **Note:** These are targets, not guarantees. Complex vulnerabilities may require more time. We'll communicate openly about any delays.
+
+---
+
+## Disclosure Policy
+
+We follow **coordinated disclosure** (also known as responsible disclosure):
+
+1. **You report** the vulnerability privately
+2. **We acknowledge** and begin investigation
+3. **We develop** a fix and prepare a release
+4. **We coordinate** disclosure timing with you
+5. **We publish** security advisory and fix simultaneously
+6. **You may publish** your research after disclosure
+
+### Our Commitments
+
+- We will not take legal action against researchers who follow this policy
+- We will work with you to understand and resolve the issue
+- We will credit you in the security advisory (unless you prefer anonymity)
+- We will notify you before public disclosure
+- We will publish advisories with sufficient detail for users to assess risk
+
+### Your Commitments
+
+- Report vulnerabilities promptly after discovery
+- Give us reasonable time to address the issue before disclosure
+- Do not access, modify, or delete data beyond what's necessary to demonstrate the vulnerability
+- Do not degrade service availability (no DoS testing on production)
+- Do not share vulnerability details with others until coordinated disclosure
+
+### Disclosure Timeline
+
+```
+Day 0 You report vulnerability
+Day 1-2 We acknowledge receipt
+Day 7 We confirm vulnerability and share initial assessment
+Day 7-90 We develop and test fix
+Day 90 Coordinated public disclosure
+ (earlier if fix is ready; later by mutual agreement)
+```
+
+If we cannot reach agreement on disclosure timing, we default to 90 days from your initial report.
+
+---
+
+## Scope
+
+### In Scope ✅
+
+The following are within scope for security research:
+
+- This repository (`hyperpolymath/network-outpost`) and all its code
+- Official releases and packages published from this repository
+- Documentation that could lead to security issues
+- Build and deployment configurations in this repository
+- Dependencies (report here, we'll coordinate with upstream)
+
+### Out of Scope ❌
+
+The following are **not** in scope:
+
+- Third-party services we integrate with (report directly to them)
+- Social engineering attacks against maintainers
+- Physical security
+- Denial of service attacks against production infrastructure
+- Spam, phishing, or other non-technical attacks
+- Issues already reported or publicly known
+- Theoretical vulnerabilities without proof of concept
+
+### Qualifying Vulnerabilities
+
+We're particularly interested in:
+
+- Remote code execution
+- SQL injection, command injection, code injection
+- Authentication/authorisation bypass
+- Cross-site scripting (XSS) and cross-site request forgery (CSRF)
+- Server-side request forgery (SSRF)
+- Path traversal / local file inclusion
+- Information disclosure (credentials, PII, secrets)
+- Cryptographic weaknesses
+- Deserialisation vulnerabilities
+- Memory safety issues (buffer overflows, use-after-free, etc.)
+- Supply chain vulnerabilities (dependency confusion, etc.)
+- Significant logic flaws
+
+### Non-Qualifying Issues
+
+The following generally do not qualify as security vulnerabilities:
+
+- Missing security headers on non-sensitive pages
+- Clickjacking on pages without sensitive actions
+- Self-XSS (requires victim to paste code)
+- Missing rate limiting (unless it enables a specific attack)
+- Username/email enumeration (unless high-risk context)
+- Missing cookie flags on non-sensitive cookies
+- Software version disclosure
+- Verbose error messages (unless exposing secrets)
+- Best practice deviations without demonstrable impact
+
+---
+
+## Safe Harbour
+
+We support security research conducted in good faith.
+
+### Our Promise
+
+If you conduct security research in accordance with this policy:
+
+- ✅ We will not initiate legal action against you
+- ✅ We will not report your activity to law enforcement
+- ✅ We will work with you in good faith to resolve issues
+- ✅ We consider your research authorised under the Computer Fraud and Abuse Act (CFAA), UK Computer Misuse Act, and similar laws
+- ✅ We waive any potential claim against you for circumvention of security controls
+
+### Good Faith Requirements
+
+To qualify for safe harbour, you must:
+
+- Comply with this security policy
+- Report vulnerabilities promptly
+- Avoid privacy violations (do not access others' data)
