+#!/usr/bin/env python3
+"""Produce an issue-triage verdict with tool-less Anthropic Messages API calls.
+
+Design rationale
+----------------
+This script holds ANTHROPIC_API_KEY, but the model it calls is given NO tools. A
+prompt injection in untrusted issue content therefore has no mechanism to read the
+runner environment or filesystem (e.g. /proc/self/environ) or to post anything; the
+model can only return text. All repo/issue context is gathered deterministically by
+the workflow and this script, and passed in as data. The comment is posted by a
+separate job that holds the GitHub token but no Anthropic key, so the secret and the
+write capability are never co-located.
+
+Two calls are made:
+  1. The model proposes a few short keyword queries for finding duplicates. The script
+     (not the model) sanitizes them and runs `gh search issues` with a read-only token,
+     pinned to this repository. The worst an injection can do here is pick a poor query.
+  2. The model returns the verdict, given the issue, templates, releases, and the
+     duplicate candidates (with truncated bodies).
+
+The prompts live in the workflow (TRIAGE_PROMPT, QUERY_PROMPT) so they are reviewed
+alongside the workflow; this script only supplies the gathered context as data.
+
+Output: a single line of JSON on stdout: {"should_comment": bool, "body": str}.
+Fails closed (no comment) on any API or parse error; exits non-zero on configuration
+errors (missing key/prompt, 4xx from the API) so they are not silently swallowed.

+# AI Contribution Policy
+
+This project **welcomes the thoughtful use of AI tools** when contributing, yet asks all contributors to follow two core principles.
+
+## Never let an LLM speak for you
+
+When maintainers read a comment, an issue, or a pull request from you, they want to know they are hearing your words. Grammar and spelling do not matter. What matters is real connection.
+
+- All comments, issues, and pull request descriptions should be written in your own voice
+- We value clear, human communication over perfect grammar or spelling
+- Avoid copy-pasting AI-generated summaries that don't reflect your own understanding
+
+AI-generated summaries tend to be long-winded, dense, and often inaccurate. Simplicity is an art. The goal is not to sound impressive, but to communicate clearly.
+
+## Never let an LLM think for you
+
+Go ahead and use AI to explore the codebase, or to write the function or test you need. But the final step before contributing should always be understanding what it has written.
+
+- Feel free to use AI tools to generate code or explore ideas
+- Only submit contributions you fully understand and can explain
+- Contributions should reflect your own reasoning and problem-solving
+
+Use AI to point you in the right direction, but always take personal responsibility. Do not quote an LLM in an issue or pull request. Maintainers want to know what you think.
+
+Our aim is ensuring quality and maintaining the joy of collaborating and communicating with real people.
+
+## Summary
+
+- AI may be used to generate code or explore ideas
+- Comments, issues, and pull request descriptions must be written in your own voice
+- Contributions must be fully understood and explainable by the contributor
+- Contribution guidelines must still be followed
+
+This policy is based on the [Human Voice policy, version 1.0.0](https://ai-policy.dev/policies/human-voice/1.0.0) from 2026-09-23. Read more about this and other AI contribution policies on [ai-policy.dev](https://ai-policy.dev/).

 `UPDATE_QUERY_COUNTS` mode requires serial execution; do not combine it with `--parallel`. You can target a single test, app, or the full suite — only the keys exercised by the run are updated. Review the resulting diff in the JSON files as part of the PR; a reviewer should be able to see and reason about every query-count change.
 
+To run the tests without enforcing the baselines, set `SKIP_QUERY_COUNTS=1`. The tests still make their requests and run their functional assertions, but the baselines are not read and the query counts are not checked against them. This helps when the same tests run against several NetBox versions, such as in a plugin's CI matrix, because query counts can differ between releases even when the tested code is unchanged. Enforce the baselines against one reference version and skip them on the others.

 ## Submitting Pull Requests
 
+!!! note "Vouched contributors"
+    Pull requests are accepted only from contributors who have been vouched for by a maintainer. If you aren't yet listed in [`.github/VOUCHED.td`](https://github.com/netbox-community/netbox/blob/main/.github/VOUCHED.td) (for example, if you're contributing for the first time), introduce yourself by [starting a discussion](https://github.com/netbox-community/netbox/discussions/new?category=vouch-request) in the **Vouch Request** category before submitting your first pull request. Pull requests from contributors who have not been vouched for are closed automatically. See the [contributing guide](https://github.com/netbox-community/netbox/blob/main/CONTRIBUTING.md) for details.
+
 Once you're happy with your work and have verified that all tests pass, commit your changes and push it upstream to your fork. Always provide descriptive (but not excessively verbose) commit messages. Be sure to prefix your commit message with the word "Fixes" or "Closes" and the relevant issue number (with a hash mark). This tells GitHub to automatically close the referenced issue once the commit has been merged.

+    This release upgrades the sorl-thumbnail dependency to v13.4.0, which fixes how cached image thumbnails resolve their storage backend. If your `STORAGES` configuration defines `OPTIONS` for a `BACKEND` path which re-exports a class defined elsewhere (for example, `storages.backends.s3boto3.S3Boto3Storage`, which is an alias of `storages.backends.s3.S3Storage`), run `manage.py thumbnail clear` once after upgrading.

+
+* [#23031](https://github.com/netbox-community/netbox/issues/23031) - Add 8C1P, 12C1P, and 24C1P trunk cable profiles
+* [#23238](https://github.com/netbox-community/netbox/issues/23238) - Support the `__empty` lookup for boolean custom field filters
+* [#23365](https://github.com/netbox-community/netbox/issues/23365) - Add a copy-to-clipboard button for site addresses
+* [#23463](https://github.com/netbox-community/netbox/issues/23463) - Include the IDs of the associated change log records (`object_change_ids`) in event data and webhook payloads
+
+### Performance Improvements
+
+* [#23076](https://github.com/netbox-community/netbox/issues/23076) - Avoid reloading deferred columns for each object when resolving the `display` field via GraphQL
+* [#23259](https://github.com/netbox-community/netbox/issues/23259) - Coalesce search cache updates rather than enqueuing a background job for each change
+* [#23286](https://github.com/netbox-community/netbox/issues/23286) - Count the IP addresses and FHRP group assignments of device and VM interfaces in REST API responses without loading the related objects
+* [#23355](https://github.com/netbox-community/netbox/issues/23355) - Prefetch the objects referenced by object custom fields when rendering REST API lists
+* [#23371](https://github.com/netbox-community/netbox/issues/23371) - Avoid deep-copying cached config context data when serializing REST and GraphQL API responses
