docs: add vulnerability disclosure statement

[AntTheLimey]

Draft deliberately. Do not merge yet - see Blockers.

Why

docs.pgedge.com/security is the single stable URL that every
repository's SECURITY.md points at, and the one a contract can cite.
It does not exist yet. Every other step of the disclosure process
depends on this page being live: deploying SECURITY.md across the
organisation publishes a link, and until this merges that link is a
404.

What this adds

• docs/security/index.md - the pgEdge Vulnerability Disclosure
  Statement: reporting route, scope, safe harbour, credit, how
  advisories and CVE identifiers are handled, and supported versions.
• mkdocs.yml - a top-level Security nav entry, placed directly
  after Welcome. This is site-wide policy rather than product
  documentation, and burying it among the extension docsets would make
  the page hard to find. Easy to move if reviewers prefer it elsewhere.
• docs/llms.txt - one line in the Resources list, so an agent reading
  the site can find the reporting route. Drop it if unwanted.

Content is the reviewed draft, unchanged

The prose is word-for-word the reviewed draft. A word-level diff
against it is empty. Only two things changed, both presentational:

• Wrapped at 79 characters, per the pgEdge docs style.
• Em-dashes replaced with hyphens, per the same style.

I did not restructure anything else. In particular the safe harbour
"good faith" clause stays as one semicolon-separated sentence rather
than becoming a bulleted list, even though the docs style would prefer
the list. That clause is in legal review, and it should not diverge
from the text being reviewed.

Spelling stays British - authorisation, safe harbour, behaviour,
programme. The site leans American, but this page has to agree
word-for-word with the approved SECURITY.md, which uses "prior
written authorisation". Consistency between the two public documents
matters more here than site-wide spelling. Flagging it rather than
deciding it.

Blockers before merge

1. Safe harbour legal review. The section commits pgEdge to third
   parties. Not yet cleared.
2. No effective date or version on the page. The approvals are not
   recorded yet and I am not inventing a date. A public policy page
   should carry one; it needs adding before merge.
3. "Latest release" needs confirming against any product that has
   its own published support lifecycle. The page already hedges with
   "where a product has its own published support lifecycle, that
   lifecycle governs", so this is a check rather than a rewrite.

Verification

• mkdocs build --strict on the page in isolation: clean, no warnings.
• Output path is /security/index.html, so with directory URLs the
  page serves at https://docs.pgedge.com/security - the URL
  SECURITY.md points at. Confirmed rather than assumed.
• mkdocs.yml still parses; nav has 49 top-level entries and exactly
  one Security.
• Rendered page produces only its seven real headings. The bold
  sentence openers do not leak into the navigation, which is the
  failure mode the docs style warns about.
• All lines within 79 characters. No em-dashes, no trailing
  whitespace, one H1.
• security is not in extra.versioned_docsets, so the
  versioned_redirects.py hook will not generate over
  docs/security/index.md.

One inconsistency found elsewhere

Not fixed here, since it is in a document still under review. The
Communication Procedure says advisories are "listed at
docs.pgedge.com/security", two sentences before saying there is no
separate index to maintain. This page does not list advisories - it
explains where they live, which is the settled decision. The procedure
wording needs correcting to match.

Summary by CodeRabbit

• New Features
  • Added a dedicated Security page with vulnerability disclosure guidance, reporting procedures, scope, safe-harbour conditions, and supported-version security information.
  • Added Security links to the site footer, Resources sections, and top-level navigation.

💡 Result:

I couldn’t find a pgEdge page at docs.pgedge.com/security or a publicly indexed pgEdge vulnerability-disclosure/safe-harbor statement. The pgEdge documentation site is available, but its indexed security pages concern PostgreSQL features and product security—not researcher disclosure policy. [1][2]

You may need to check pgEdge’s main website or contact pgEdge directly for its current security-reporting process.

GitHub Dependabot alerts Go vulnerability database advisories dependency detection enabled alerts documentation

💡 Result:

GitHub Dependabot integrates with the Go ecosystem by leveraging the GitHub Advisory Database, which includes curated vulnerability data for Go modules [1][2]. How Dependabot Detects Go Vulnerabilities: 1. Dependency Graph Analysis: GitHub maintains a dependency graph for your repository by analyzing manifest files, specifically go.mod files [3][4]. This allows GitHub to understand your project's dependencies, including transitive dependencies [4][5]. 2. Database Cross-Referencing: GitHub continuously monitors the GitHub Advisory Database, which incorporates data from the canonical Go vulnerability database (vuln.go.dev) [1][6][2]. 3. Alert Generation: When a new GitHub-reviewed advisory is added to the database that affects a package identified in your dependency graph, Dependabot automatically generates an alert for your repository [7][4][8]. Enabling Dependabot Alerts: You can enable Dependabot alerts at the repository, organization, or personal account level [9][10]. - Repository Level: Navigate to your repository on GitHub, click Settings, select Advanced Security under the Security section, and click Enable next to Dependabot alerts [9][10][11]. - Automation: You can also configure alerts to be automatically enabled for all new repositories created within your personal account or organization [9][10]. Important Considerations: - Curated Data: Dependabot only generates alerts for advisories that have been reviewed by GitHub to ensure they meet quality and validity standards [1][2][4]. - Timing: Alerts are triggered when your dependency graph changes (e.g., you push a commit that updates a manifest file) or when a new advisory is added to the GitHub Advisory Database [7][4][8]. - Tooling: While Dependabot provides automated alerts and can propose security updates (pull requests to upgrade dependencies), developers can also use the govulncheck tool locally to scan their projects against the official Go vulnerability database [3][6][4].

Qualify the Dependabot notification claim.

Dependabot alerts require a detected dependency, a matching GitHub Advisory Database record, and enabled alerts. A Go vulnerability database entry alone does not guarantee an alert for every consumer. Replace “will report them to you” with conditional wording.

Define the supported-version baseline.

The documentation navigation defines the latest version, but this policy does not state whether that version is the security baseline. Define “latest release” for each product and link to each product’s support lifecycle. State which rule controls when the rules differ.
