 # Changelog
 
+## 1.0.3 - 2026-10-18
+
+- Add `docs/maintenance.md`. It tells you who maintains the gem, how CI checks
+  each change, how a release is published, what you keep if maintenance
+  stops, and how to become a maintainer. The README and the comparison pages
+  now link to this page. They and `docs/versioning.md` no longer state a count
+  of maintainers. A new test fails when a page states one.
+
 ## 1.0.2 - 2026-10-15
 
 - Add two comparison pages in `docs/compare/`: Solid Queue

+# Maintenance and continuity
+
+This page tells you who maintains Solid Objects, how a release is made, and
+what you keep if maintenance stops. It also tells you how to help maintain the
+project.
+
+## Who maintains it
+
+Lucas Carlson ([@cardmagic](https://github.com/cardmagic)) is the lead
+maintainer of the Ruby gem `solid_objects` and of the npm package
+[`solid-objects`](https://github.com/cardmagic/solid-objects-js). The two
+packages use the same model and the same correctness contract. A change to the
+model goes into both packages, and the
+[parity ledger](https://github.com/cardmagic/solid-objects-js/blob/main/docs/parity.md)
+records each difference between them.
+
+The same maintainer sells [Solid Objects Pro](https://solidobjects.pro), a
+commercial package that batches operations at scale. Pro depends on this gem.
+This gem does not depend on Pro, and it needs no account, license key, or
+service from the maintainer.
+
+## How a change is checked
+
+CI runs on each push and each pull request:
+
+- The full test suite on SQLite, on each pair of Ruby 3.3, 3.4, or 4.0 and
+  Rails 7.1, 7.2, 8.0, or 8.1.
+- The full test suite on PostgreSQL and on MySQL, with both MySQL clients.
+- Standard, RuboCop, RBS, Steep, and Brakeman.
+
+[Compatibility and maturity](virtual-actors.md#compatibility-and-maturity)
+lists the supported versions. The [correctness contract](correctness.md) lists
+the guarantees that the tests check.
+
+## How a release is made
+
+1. The maintainer pushes a version tag, for example `v1.0.3`.
+2. GitHub Actions runs all test jobs again on that tag.
+3. If all test jobs pass, GitHub Actions builds the gem and pushes it to
+   RubyGems with trusted publishing. The repository keeps no RubyGems key.
+4. The same job makes a GitHub release and attaches the gem file.
+
+[Versioning](versioning.md) tells you what a release can change.
+`CHANGELOG.md` lists each release.
+
+## What you keep if maintenance stops
+
+- **Your data.** Actor state, mailboxes, reminders, and effects are rows in
+  your application's database. [Database schema](database-schema.md) describes
+  each table. No service of the maintainer holds your data.
+- **The code.** The [MIT License](../MIT-LICENSE) lets anyone use, change,
+  fork, and publish the code.
+- **The checks.** The tests and the CI configuration are in this repository. A
+  fork can check its changes with the same suite.
+
+## Help maintain Solid Objects
+
+The project wants more maintainers. Experience with Rails, with locks and
+transactions in PostgreSQL or MySQL, or with TypeScript and Node.js helps.
+
+1. Read [CONTRIBUTING.md](../CONTRIBUTING.md).
+2. Send a small pull request: a fix, a test, or a correction to a guide.
+3. After some of your pull requests are merged, open an
+   [issue](https://github.com/cardmagic/solid-objects-ruby/issues) to ask to
+   become a maintainer.
