+#                               applies to. Default: 'includes'
+#   has_js            (boolean) Whether to run JS linting. Default: false
+#   phpcs_autofix     (boolean) On pull_request events: run phpcbf and commit any fixes

+#                               skip the commit (no loop) but still run strict phpcs.

+#   file-size   300-line rule enforcement (skipped when enforce_300: false).
+#   phpunit     PHPUnit across php_versions matrix (skipped when tests: none).
+#   lint-js     JS linting (skipped when has_js: false).
+#
+# Design notes:
+#   - phpcbf auto-commit pattern is the prautoblogger gold standard (see
+#     prautoblogger/.github/workflows/ci.yml). The GITHUB_TOKEN commit does
+#     NOT trigger a new CI run per GitHub's loop-prevention rules.
+#   - WP test framework path replicates peptide-starter-theme's three gotchas:
+#     (1) install svn — ubuntu-latest no longer ships it;
+#     (2) MySQL service pre-creates the DB via MYSQL_DATABASE, so pass
+#         skip-db-create=true as the 6th arg to install-wp-tests.sh;
+#     (3) WP_CORE_DIR must have a trailing slash (bootstrapped into ABSPATH
+#         and concatenated verbatim — missing slash produces wrong path).
+#   - Every repo calls `composer test` regardless of the `tests` input; the
+#     input only controls environment provisioning, not the command.
+#   - permissions: the phpcs job declares `contents: write` at job level for
+#     phpcbf commit-back. GitHub requires the CALLING WORKFLOW to also declare
+#     `permissions: contents: write` at the caller's workflow level — GH enforces
+#     that callers cannot be escalated beyond their declared scope, even by job-level
+#     overrides in the reusable workflow. All caller repos must include this.

+
+### Fixed
+- **P2-A injection** (`ci.yml:239`): `${{ inputs.line_limit_paths }}` moved
+  from raw shell assignment into an `env:` block (`PATHS`); shell now reads
+  `$PATHS` — eliminates template-injection surface for caller-supplied input.
+- **P2-B lint-js fallback** (`ci.yml:378`): replaced `npm run lint --if-present`
+  (exits 0 when no lint script exists, killing the fallback branch) with
+  explicit `node -e "process.exit(…)"` detection; `node --check` scan now
+  actually runs when no `lint` npm script is defined.
+- **P2-C phpcs config mismatch** (`ci.yml:178-199, 206-223`): both phpcbf
+  and phpcs steps now detect which of `phpcs.xml` / `phpcs.xml.dist` /
+  `.phpcs.xml.dist` is present and pass that file to `--standard`; guard and
+  command now agree for all three variants.
+
+
+### Added
+- **Reusable CI workflow** (`.github/workflows/ci.yml`).
+  `on: workflow_call` entrypoint that every estate repo will adopt as a thin
+  caller. Inputs: `php_versions` (JSON matrix), `tests`
+  (stubs|wp-framework|brain-monkey|none), `enforce_300`, `line_limit_paths`,
+  `has_js`, `phpcs_autofix`. Fixed job names (`lint-php`, `phpcs`, `file-size`,
+  `phpunit`, `lint-js`) so deploy-app.yml can `needs:` them uniformly.
+  - **phpcbf auto-commit** (prautoblogger gold-standard pattern): on
+    `pull_request` events, phpcbf runs and pushes any fixes back to the branch
+    before strict PHPCS; on `push` events auto-commit is skipped to prevent
+    loops.
+  - **wp-framework PHPUnit path** replicates all three peptide-starter-theme
+    gotchas: (1) install svn; (2) pass skip-db-create=true so the MySQL
+    service's pre-created DB is reused; (3) WP_CORE_DIR trailing slash.
+  - **Self-test caller** (`.github/workflows/ci-self-test.yml`): exercises
+    the reusable workflow on this repo with `tests: none` so the workflow is
+    validated on this PR itself.
+  - **README.md**: adoption snippet documenting how any repo becomes a caller.

+# peptide-e2e
+
+Playwright smoke tests and shared CI/CD pipelines for the [peptiderepo.com](https://peptiderepo.com) estate.
+
+## Reusable workflows
+
+This repo hosts shared GitHub Actions workflows called by all 7 app repos.
+
+### `deploy-app.yml` — shared deploy pipeline
+
+Handles staging rsync → Playwright smoke → production rsync → inventory guard →
+LiteSpeed cache purge → health check. Called by every app's `deploy.yml` via
+`uses: peptiderepo/peptide-e2e/.github/workflows/deploy-app.yml@main`.
+
+### `ci.yml` — reusable CI (PHP lint, PHPCS, 300-line, PHPUnit, JS lint)
+
+Standardised CI for every estate repo. Consistent job names so `deploy-app.yml`
+can gate on them uniformly.
+
+**Adopt in any repo** — create `.github/workflows/ci.yml` in the caller repo:
+
+```yaml
+name: CI
+
+on:
+  push:
+    branches: [main]
+  pull_request:
+    branches: [main]
+
+# Required: the called ci.yml phpcs job declares contents: write for phpcbf
+# commit-back. GitHub enforces that callers must grant at least the permission
+# level the reusable workflow's jobs request.
+permissions:
+  contents: write
+
+jobs:
+  ci:
+    uses: peptiderepo/peptide-e2e/.github/workflows/ci.yml@main
+    with:
+      tests: stubs        # stubs | wp-framework | brain-monkey | none
+      has_js: false       # set true if the repo ships JS
+    secrets: inherit
+```
+
+**Full input reference:**
+
+| Input | Type | Default | Description |
+|-------|------|---------|-------------|
+| `php_versions` | string | `'["8.1","8.2","8.3"]'` | JSON array of PHP versions to matrix over |
+| `tests` | string | `stubs` | PHPUnit environment: `stubs`, `wp-framework`, `brain-monkey`, or `none` |
+| `enforce_300` | boolean | `true` | Fail if any tracked `*.php` file under `line_limit_paths` exceeds 300 lines |
+| `line_limit_paths` | string | `includes` | Space-separated paths the 300-line rule applies to |
+| `has_js` | boolean | `false` | Whether to run JS linting (`npm run lint` or `node --check`) |
+| `phpcs_autofix` | boolean | `true` | On PRs: run phpcbf and commit fixes back before strict PHPCS |
+
+**PHPUnit `tests` values explained:**
+
+- `stubs` — WP stubs only (fast, no DB); just runs `composer test`.
+- `brain-monkey` — Brain Monkey mocking; no DB; runs `composer test`.
+- `wp-framework` — Full WordPress test framework: provisions MySQL service,
+  installs svn, runs `bin/install-wp-tests.sh`, then `composer test`. Handles
+  the three known gotchas: svn install, `--skip-db-create` with MySQL service,
+  `WP_CORE_DIR` trailing slash.
+- `none` — Skips the `phpunit` job entirely (temporary; repos without a suite
+  yet; remove at rollout).
+
+**phpcbf auto-commit:** on `pull_request` events, phpcbf runs first and commits
+any auto-fixable violations back to the PR branch via `GITHUB_TOKEN`. GitHub
+prevents loops — bot commits do not trigger a new CI run. Strict PHPCS then
+runs and fails only on non-auto-fixable violations.
+
+**Job names** (fixed — callers and `deploy-app.yml` `needs:` these):
+`lint-php`, `phpcs`, `file-size`, `phpunit`, `lint-js`.
+
+## Smoke tests
+
+The `tests/` directory contains Playwright specs that run against
+`https://staging.peptiderepo.com` (via `deploy-app.yml`) and can also target
+production. See `playwright.config.ts` for environment configuration.
