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

Demonstrates the drop-in pattern: adding a step with a form is a single
new file under includes/steps/, plus one small extension to the base
abstraction.
WPH_Step gains:
- render_extra($session_state) — emit extra HTML inside the step card
- handle_action($name, $input) — handle a step-specific POST and
return a finding to record
New generic admin-post handler wph_step_action routes form submissions
to the matching step's handle_action() with nonce verification.
The email step (includes/steps/115-email.php):
- Detects 7 known SMTP plugins, surfaces default From address
- Renders a To: input prefilled with the current admin's email
- Sends via wp_mail() with wp_mail_failed capture so failures show the
underlying error
- Records the outcome as a 'last_send' finding so it appears on the
step card, in the summary, and in the downloadable report
Infrastructure:
- WPH_Step::autocheck($session_state) returns an array of findings
shaped {id, level: ok/warn/bad/info, label, value, detail}.
- WPH_Session stores results keyed by step id (persisted in the option-
backed session).
- WPH_Step::has_autocheck() reflection check so the UI only renders the
panel for steps that implement automation.
- 'Run checks' / 'Refresh' button per step, admin-post handler runs
autocheck() and stashes the result on the session.
- Findings rendered as a coloured table on the step card; included
verbatim in the Markdown report with status icons.
Step automations implemented:
- Step 1 (Backup): detection of 11 known backup plugins by slug;
active/inactive state; UpdraftPlus last-backup timestamp.
- Step 2 (Environment): PHP version + EOL, WP version vs latest, disk
usage, wp-config flags, file perms on wp-config/wp-content/uploads,
error-log sizes.
- Step 4 (Plugins): WP.org API enrichment with 24h transient cache —
last_updated, active_installs, abandonment flag, removed-from-repo
flag, update-available count. Summary line at the top.
- Step 8 (Security): SSL cert expiry via stream_socket_client +
openssl_x509_parse, administrator audit, xmlrpc reachability, login
URL hardening detection.
- Step 9 (Database): spam comments, post revisions, autoload size (WP
6.6+ value handling), top 3 largest tables.
- Step 11 (Small fixes): deactivated-but-installed plugin list,
homepage alt-text scan.
Smoke-tested on testsite — all six steps return findings with
correctly-classified levels. Report regenerated with automated findings
section.
Plugin skeleton, drop-in step registry, option-backed session, single-page
checklist UI, downloadable Markdown report. Steps live as one file each
under includes/steps/ — adding/removing one is a single file change.
Step IDs are stable strings so renaming files preserves session data.
Architecture (hc-5ix.3): WPH_Steps singleton globs includes/steps/*.php,
natsort-orders by filename, requires each file (which returns a WPH_Step
instance), then applies a 'wph_steps' filter so installs can drop steps.
Session (hc-5ix.4): option-backed (per decision — plugin is installed
per-engagement, so DB-resident history would be lost on uninstall).
Single in-progress session per site; finished sessions render a report
that the user downloads/copies.
Recovery bootstrap (hc-5ix.1): detects whether wp-site-recovery is
installed + active, surfaces state on the start panel and in every
active session. Manual install for now; private update channel deferred
to hc-5ix.27.
Smoke-tested on testsite: registry discovery (13 steps in correct order),
start → update_step → progress count → finish → 8KB Markdown report →
discard cycle.
