This pull request updates the MSC4284 policy server implementation to better match the now stabilised MSC.

Related Synapse pull request: https://github.com/element-hq/synapse/pull/19503

  • Update m.room.policy schema
  • Update event type to support both stable and unstable types
  • Drop legacy check endpoint
  • Verify policy server signatures when checking
  • Fall back to fetching a fresh signature if one is not attached to an event

Will also add:

  • Support for advertising /.well-known/matrix/policy_server
  • Support for the stable and unstable endpoints, hopefully with some built-in checks (for example to enforce DAG "correctness") and/or the option to pass through to another service

Pull request checklist:

  • This pull request targets the main branch, and the branch is named something other than
    main.
  • I have written an appropriate pull request title and my description is clear.
  • I understand I am responsible for the contents of this pull request.

If you aren't sure about some, feel free to ask for clarification in #dev:continuwuity.org. --> - [x] This pull request targets the `main` branch, and the branch is named something other than `main`. - [x] I have written an appropriate pull request title and my description is clear. - [x] I understand I am responsible for the contents of this pull request. - I have followed the [contributing guidelines][c1]: - [x] My contribution follows the [code style][c2], if applicable. - [x] I ran [pre-commit checks][c1pc] before opening/drafting this pull request. - [ ] I have [tested my contribution][c1t] (or proof-read it for documentation-only changes) myself, if applicable. This includes ensuring code compiles. - [x] My commit messages follow the [commit message format][c1cm] and are descriptive. - [x] I have written a [news fragment][n1] for this PR, if applicable<!--(can be done after hitting open!)-->. <!-- Notes on these requirements: - While not required, we encourage you to sign your commits with GPG or SSH to attest the authenticity of your changes. - While we allow LLM-assisted contributions, we do not appreciate contributions that are low quality, which is typical of machine-generated contributions that have not had a lot of love and care from a human. Please do not open a PR if all you have done is asked ChatGPT to tidy up the codebase with a +-100,000 diff. - In the case of code style violations, reviewers may leave review comments/change requests indicating what the ideal change would look like. For example, a reviewer may suggest you lower a log level, or use `match` instead of `if/else` etc. - In the case of code style violations, pre-commit check failures, minor things like typos/spelling errors, and in some cases commit format violations, reviewers may modify your branch directly, typically by making changes and adding a commit. Particularly in the latter case, a reviewer may rebase your commits to squash "spammy" ones (like "fix", "fix", "actually fix"), and reword commit messages that don't satisfy the format. - Pull requests MUST pass the `Checks` CI workflows to be capable of being merged. This can only be bypassed in exceptional circumstances. If your CI flakes, let us know in matrix:r/dev:continuwuity.org. - Pull requests have to be based on the latest `main` commit before being merged. If the main branch changes while you're making your changes, you should make sure you rebase on main before opening a PR. Your branch will be rebased on main before it is merged if it has fallen behind. - We typically only do fast-forward merges, so your entire commit log will be included. Once in main, it's difficult to get out cleanly, so put on your best dress, smile for the cameras! --> [c1]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md [c2]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/docs/development/code_style.mdx [c1pc]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#pre-commit-checks [c1t]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#running-tests-locally [c1cm]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#commit-messages [n1]: https://towncrier.readthedocs.io/en/stable/tutorial.html#creating-news-fragments
