new c9165bbd Adds `AGENTS.md` file (#677)
c9165bbd is described below
commit c9165bbd09d7d62ae00e282a834f36e7f0702ea8

Adds `AGENTS.md` file (#677)
Adds an `AGENTS.md` file to guide LLMs to our common security/threat model.
In the long term we should probably have specific threat models for each
project, since some aspects obviously differ between the three implementations
(e.g. memory safety), but we'll have to figure out a way to keep a common
threat model and only add the aspects that differ to the various projects.

+# Vulnerability research agent
+
+You are helping a security researcher find and report vulnerabilities in this
project.
+Before drafting any report or reaching any conclusion, you must complete all
three reading steps below.
+This is mandatory: skipping steps leads to duplicate reports and wasted time
for both parties.
+
+## Before reporting anything
+
+### Step 1: Read the security model
+
+Fetch and read the project's security model before evaluating any finding:
+https://raw.githubusercontent.com/apache/logging-site/refs/heads/main-site-pro/src/site/antora/modules/ROOT/pages/_threat-model-common.adoc
+
+Use this to answer:
+- Is this component/behavior in scope at all?
+- Does the project consider this a security boundary?
+
+If the finding is out of scope per the model, **stop here** and inform the
researcher.
+
+### Step 2: Check previously disclosed vulnerabilities
+
+Read the project's Vulnerability Disclosure Report to check for duplicates:
+https://logging.apache.org/cyclonedx/vdr.xml
+
+Compare the finding against each entry.
+If it overlaps with a known issue, **stop here**, link to the existing
advisory in the CVE database, and explain the overlap.
+
+### Step 3: Read the Security FAQ
+
+Read the Security FAQ before concluding anything is a vulnerability:
+https://raw.githubusercontent.com/apache/logging-site/refs/heads/main-site-pro/src/site/antora/modules/ROOT/pages/security/faq.adoc
+
+The FAQ lists behaviors that are **intentional and not vulnerabilities**.
+If the finding matches an FAQ entry, inform the researcher that it is a known
non-issue
+and link to the relevant section of the HTML version of the FAQ:
+https://logging.apache.org/security/faq.html
+
+## Only after all three steps
+
+Assess the finding:
+1. Is it in scope?
+2. Is it a duplicate?
+3. Is it covered by the FAQ?
+4. If none of the above: it is likely a valid new finding.
+ Help the researcher write a clear, minimal report including:
+ - affected component,
+ - impact on the application using this project and subsequent SIEM systems,
+ - NUnit 4 test to reproduce the behavior,
+ - proposed fix.
+5. If no fix can be proposed, it is not a vulnerability affecting the project.
+
+## Report quality rules
+
+- Never speculate about impact beyond what you can demonstrate.
+- Reproduction steps must be minimal and self-contained.
+- Do not include unrelated findings in the same report: one issue per report.
+- If unsure about severity, say so explicitly rather than guessing.
