Add .github/workflows/ci.yml as a reusable workflow_call entrypoint for
all 7 estate repos. Consistent job names (lint-php, phpcs, file-size,
phpunit, lint-js) so deploy-app.yml can needs: them uniformly.

Inputs: php_versions (JSON matrix), tests (stubs|wp-framework|brain-monkey|none),
enforce_300, line_limit_paths, has_js, phpcs_autofix.

phpcbf auto-commit: on pull_request, phpcbf runs and commits any auto-fixable
PHPCS violations back to the branch via GITHUB_TOKEN before strict phpcs.
On push events the commit step is skipped to prevent loops.

wp-framework PHPUnit path handles all three known WP CI gotchas:
(1) install svn (ubuntu-latest lacks it);
(2) skip-db-create=true (MySQL service pre-creates wp_tests via MYSQL_DATABASE);
(3) WP_CORE_DIR trailing slash (ABSPATH concatenation guard).

Also adds:
- .github/workflows/ci-self-test.yml: self-test caller (tests: none) so the
  reusable workflow is exercised on this PR.
- README.md: adoption snippet + full input reference for caller repos.
- CHANGELOG.md: v1.6.0 entry.

+#                               300 lines (the estate hard rule). Default: true
+#   line_limit_paths  (string)  Space-separated directory/path(s) the 300-line rule
+#                               applies to. Default: 'includes'
+#   has_js            (boolean) Whether to run JS linting. Default: false

+#                               back to the branch before strict phpcs. On push events:
+#                               skip the commit (no loop) but still run strict phpcs.
+#                               Default: true
+#
+# Job names (fixed — callers and deploy-app.yml gate on these):
+#   lint-php    PHP syntax check across php_versions matrix.
+#   phpcs       WordPress Coding Standards; phpcbf auto-commit on PRs.
+#   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.

+  (stubs|wp-framework|brain-monkey|none), `enforce_300`, `line_limit_paths`,
+  `has_js`, `phpcs_autofix`. Fixed job names (`lint-php`, `phpcs`, `file-size`,

+  - **phpcbf auto-commit** (prautoblogger gold-standard pattern): on

+# 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]
+
+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.

Subject: [PATCH 02/11] fix(ci-self-test): use relative path for same-repo
 reusable workflow call

GitHub requires ./.github/workflows/ci.yml (not @branch-ref) for same-repo
reusable workflow calls from a PR branch. The @claude/reusable-ci-20260616
ref caused startup_failure because GitHub can't resolve branch-ref reusable
workflows that aren't on main yet.

Subject: [PATCH 06/11] fix(ci): move permissions: contents: write to phpcs job
 level
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Workflow-level permissions: write in a reusable workflow causes startup_failure
when calling workflow has default (read-only) permissions. Move write scope to
the phpcs job level only — the one job that actually needs it (phpcbf commit-back).
All other jobs run with the inherited read scope.

Self-test caller (ci-self-test.yml) confirmed clean with no top-level write
permission declared — job-level override in the reusable workflow is sufficient.

Confirmed via bisect: ci-bisect.yml (workflow-level write) startup_failed;
ci-minimal.yml (no write needed) succeeded; ci-bisect-caller with
permissions: write added succeeded. Job-level approach is the correct pattern.

GitHub Actions permission model for reusable workflows: callers must declare
at least the permission level that any job in the called workflow requests.
Since the phpcs job declares 'permissions: contents: write' (for phpcbf
commit-back), all callers must include 'permissions: contents: write' at
their workflow level.

Changes:
- ci.yml: remove top-level permissions block (was: contents: read); phpcs job
  already has job-level contents: write. Docblock now explains the caller
  requirement clearly.
- ci-self-test.yml: add 'permissions: contents: write' at workflow level.
- README.md: adoption snippet now includes the required permissions block.
- Remove diagnostic bisect/minimal test workflows (used to identify the root
  cause of startup_failure; finding: job-level write in reusable workflow
  requires caller to declare write at workflow level).

Confirmed: ci-bisect-caller with permissions: contents: write = SUCCESS.
Confirmed: actionlint 1.7.4 + yamllint 1.38.0 both clean.

Subject: [PATCH 10/11] fix(ci): graceful PHPCS skip when phpcs.xml not present

Add guard to phpcbf and phpcs strict steps: if neither phpcs.xml,
phpcs.xml.dist, nor .phpcs.xml.dist exists in the repo root, both steps
exit 0 with an info message. This prevents startup_failure on the self-test
(peptide-e2e is a Node repo with no PHPCS config) and provides clean
feedback for repos not yet configured for PHPCS.

Real PHP repos all have a phpcs.xml (prautoblogger, theme, pr-core, etc.)
so the guard is transparent for them.

Subject: [PATCH 11/11] fix(ci): P2-A injection, P2-B lint-js fallback, P2-C
 phpcs config detection

P2-A: move ${{ inputs.line_limit_paths }} from raw shell into env: block (PATHS)
      to eliminate template-injection surface on caller-controlled input.
P2-B: replace 'npm run lint --if-present' (always exits 0 on missing script,
      killing the node --check fallback) with explicit node -e detection;
      fallback now actually runs when no lint npm script is defined.
P2-C: both phpcbf and phpcs steps now detect which of phpcs.xml /
      phpcs.xml.dist / .phpcs.xml.dist is present and pass it to --standard;
      guard and command now agree for all three config filename variants.

Validators: actionlint 1.7.4 clean, yamllint 1.38.0 clean (both files).
Version: 1.6.1
