+# Dotkernel packages lifecycle page
+
+The page lists Dotkernel's open-source packages with their support status.
+It renders a pre-generated JSON file, so the request path never calls GitHub.
+
+## Where this lives
+
+- Published page: <https://www.dotkernel.com/dotkernel-packages-oss-lifecycle/>
+- Data file: <https://www.dotkernel.com/dotkernel-packages.json>
+- Source repository: <https://github.com/dotkernel/dotkernel.com>
+
+Every path below is relative to the root of `dotkernel/dotkernel.com`.
+If the current working directory is a different project, the change belongs in that repository, not here - clone it or switch to that checkout before editing.
+
+## The pieces
+
+| Concern             | Path in `dotkernel/dotkernel.com`                                         |
+|---------------------|---------------------------------------------------------------------------|
+| Route               | `src/App/src/RoutesDelegator.php`                                         |
+| Handler (read-only) | `src/App/src/Handler/GetPackagesViewHandler.php`                          |
+| Template            | `src/Blog/templates/page/dotkernel-packages-oss-lifecycle.html.twig`      |
+| Card styles         | `src/App/assets/scss/components/_custom.scss` (`Package lifecycle cards`) |
+| Generator           | `src/App/src/Service/PackageGenerator.php`                                |
+| GitHub transport    | `src/App/src/Service/GitHubClient.php`                                    |
+| Config              | `config/autoload/packages.global.php`                                     |
+| CLI entry point     | `bin/generate-packages`                                                   |
+| Data file           | `public/dotkernel-packages.json` (gitignored)                             |
+
+Two rules follow from this split, and breaking either is the usual cause of a confusing result:
+
+- The handler only reads.
+A change to the generator shows up on the page only after the data file is rebuilt.
+- The data file is gitignored, so it does not travel with a deploy.
+Production depends on the cron run.
+
+## How a repository gets onto the page
+
+A repository is a published package when it contains an `OSSMETADATA` file with an `osslifecycle` value.
+
+```text
+osslifecycle=active
+```
+
+There is no allow-list to edit.
+To keep a repository off the page, add its bare name (case-insensitive) to `ignoreRepos` in `config/autoload/packages.global.php`.
+
+Recognized values, which are also the display order (`LIFECYCLE_ORDER`): `active`, `maintenance`, `security-only`, `archived`.
+Anything else is kept, sorted last, and rendered with the muted `package-card--unknown` treatment.
+For equal lifecycles, the sorting is by repository name.
+
+Each entry in the data file is built from three sources:
+
+- `name`, `url`, `description`, `archived` - the `/orgs/{org}/repos` listing, so they cost no extra request.
+- `lifecycle` - the repository's `OSSMETADATA`.
+- `php` - `require.php` in the repository's `composer.json`; if no value is found, it defaults to `null`.
+
+`description` and `php` are `null` for anything unusable rather than an empty string, and the template omits the element instead of rendering a blank one.
+
+## Regenerating
+
+From the root of a `dotkernel/dotkernel.com` checkout:
+
+```bash
+php bin/generate-packages
+```
+
+Credentials are saved in `config/autoload/local.php` under the `github` key (`authBearer`, `userAgent`, `org`) - see `local.php.dist`.
+If no token is set, unauthenticated requests still work but have a much lower rate limit.
+
+The run is deliberately conservative: it writes to a `.tmp` sibling and renames, and it aborts with exit code 1 if more than 20% of per-repository requests fail (`FAILURE_THRESHOLD`), leaving the previous listing in place.
+A non-zero exit means the page keeps serving yesterday's data, which is the intended outcome.
+
+## Reading the output
+
+- `Skipped by ignoreRepos: …` - informational, those repositories were excluded on purpose.
+- `WARNING: ignoreRepos entries matched nothing (renamed or deleted?)` - stale `ignoreRepos` entries.
+Prune them, or a renamed repository silently reappears on the site.
+- `WARNING: <repo>: could not read OSSMETADATA (…)` - the request failed and counts toward the 20% threshold.
+The repository is left off this run.
+- `WARNING: <repo>: OSSMETADATA present but no osslifecycle value found, skipped` - the file exists but has no parsable `osslifecycle=`; fix it in that repository.
+- `WARNING: <repo>: could not read composer.json (…)` - costs the PHP badge constraint, not the package.
+
+## After changing anything in the page
+
+- If the payload changed shape, rerun `php bin/generate-packages`, since the local data file predates the change.
+- If the SCSS is updated, run `npm run build`.
+`public/css/app.css` is tracked, so the compiled file must be committed with the source.
+- Run the test battery using `vendor/bin/phpunit`, `vendor/bin/phpcs`, and `vendor/bin/phpstan analyse`.
+Coverage lives in `test/Unit/App/Service/PackageGeneratorTest.php`, `test/Unit/App/Factory/PackageGeneratorFactoryTest.php`, and `test/Unit/App/Handler/GetPackagesViewHandlerTest.php`.
+- If the data file is renamed, update `packages.global.php`, `.gitignore`, the "View as JSON" link in the template, and the fallback default in `src/App/src/Factory/PackageGeneratorFactory.php`.
