Steve Hanlon 1782e52504 Central history server + plugin write-through sync (epic hc-0p1)
Adds a PHP/SQLite history server in server/ and refactors the plugin to
write every session change through it. Healthcheck history now survives
plugin uninstall and groups across dev + live URLs for the same engagement
via an editable site_key (defaults to the normalised host).

Server (server/):
- Front controller + hand-rolled autoloader, no framework, no composer
- SQLite default DSN; swap to MySQL by changing config.php
- Schema: healthchecks (PK id, UNIQUE (site_key, started_at)) + step_updates
  (PK (healthcheck_id, step_id)) + request_log; auto-migration runner
- 8 endpoints: POST/GET/PUT healthchecks, PUT/GET step rows, GET step history
  with exclude_id, GET /sites (recent), GET /step-counts (badge data)
- Bearer auth via hash_equals; HTTPS expected (plugin enforces client-side)
- DEPLOY.md with Apache/nginx vhosts, Let's Encrypt, SQLite backup cron,
  and the /home/www/ perm gotcha
- dev-router.php works around PHP -S 405-ing dotted uniqid paths

Plugin:
- ATT_HC_Api HTTP client reads ATT_HC_API_URL/ATT_HC_API_KEY constants
  from wp-config.php; refuses non-HTTPS with a loopback dev exception
- ATT_HC_Session is now write-through: every start/update_step/finish/
  set_autocheck POSTs or PUTs to the server first, then updates the local
  WP option cache. No drift possible — failures throw ATT_HC_Api_Exception
- previous() now reads from /healthchecks?include=steps and reconstructs;
  the old att_hc_previous_session local option is gone
- ATT_HC_Session::resume(id) hydrates a server session into the local cache
- Start screen: editable site_key (defaults to normalise_site_url()),
  datalist of recent engagements, table of in-progress sessions for the
  chosen key with Resume buttons. Double-click guard on start + resume
  handlers short-circuits if a session is already active
- Per-step <details> disclosure shows "Previous notes (N)" badge from
  /step-counts; lazy-loads detail rows on first expand via admin-ajax,
  caches via data-loaded, resets on error so user can retry
- All admin handlers catch ATT_HC_Api_Exception and surface via
  att_hc_api_error transient → admin notice
- Hard config-error gate at the top of the admin page blocks the UI when
  ATT_HC_API_URL/ATT_HC_API_KEY are missing or malformed

Site Healthcheck

Internal WordPress plugin that walks a technician through a structured healthcheck. Companion to wp-site-recovery, which it expects to be installed as step 0.

Install

ln -s ~/dev/wp-healthcheck /path/to/wp/wp-content/plugins/att-site-healthcheck

Then activate from Plugins. Settings appear under Tools → Site Healthcheck.

Use

  1. Open Tools → Site Healthcheck.
  2. Confirm the recovery plugin status panel shows ✓ active.
  3. Click Start new healthcheck.
  4. Work through each step card. For each: choose a status (done / skipped / blocked / n/a) and add notes.
  5. Click Finish & generate report.
  6. Download the Markdown report or copy it to clipboard.

One in-progress session per site at a time. Reports are not stored in the database (the plugin is meant to be uninstalled at the end of each engagement) — download them.

Adding, removing, reordering steps

Each step is a single file under includes/steps/ named <order>-<slug>.php.

<?php
// includes/steps/45-staging.php
return new class extends ATT_HC_Step {
    public function id(): string { return 'staging'; }
    public function title(): string { return 'Step 4.5 — Verify Staging Sync'; }
    public function sub_items(): array {
        return ['Re-deploy from production', 'Run smoke tests'];
    }
};
  • Add: drop a new file.
  • Remove: delete the file.
  • Reorder: rename the numeric prefix (steps are loaded in natsort order).
  • Conditionally drop on one install: use the att_hc_steps filter to unset the step by id.

Stable string IDs (returned by id()) are what's stored in session data, so renaming a file does not break in-progress sessions as long as the id stays the same.

Phase roadmap

Phase 1 (this) is a checklist + Markdown report. Phase 3 will add per-step automation — backup detection, env auto-collect, plugin update intelligence, PageSpeed Insights, SSL checks, etc. See beads epic hc-5ix for the full plan.

Distribution

Internal/agency tool — not a WP.org plugin (decision hc-5ix.26). Distributed as a built ZIP. A self-hosted update channel is hc-5ix.27 on the phase-3 backlog.
