Phase 3 v2: all step automations + cross-cutting UI
Step automations (six more): - Step 3 (Core): current vs latest WP version, db upgrade flag, auto- update policy, safe-update sequence reminder. - Step 5 (Theme): parent/child detection, customisation warning when non-default theme without child, theme update available, inactive theme list. - Step 6 (Visual): mShots screenshot URL, key-page HEAD checks (home, login, posts page, WC shop/cart/checkout), mixed-content scan. - Step 7 (Performance): keyless PageSpeed Insights v5 API (mobile + desktop, cached 12h, skipped on .local), caching plugin detection, heavy-image scan (>500KB). - Step 10 (Uptime): monitoring plugin detection (ManageWP, MainWP, Jetpack, WP Umbrella, UptimeRobot), www/non-www canonical check. - Step 12 (Wrap-up): cross-step rollup — bad/warn counts, blocked steps, top examples for the technician's final glance. Cross-cutting: - Sticky step-index sidebar with status dots per step (the linear- stepper alternative that keeps the overview). - 'Stop & escalate' summary card at top listing blocked steps with escalation guidance and notes. - Previous-session snapshot stored on finish; diff banner on the next session shows new/resolved/changed counts. - HTML report builder (printable, inline-styled). Download HTML, Download Markdown, Copy, and Email actions on the finish panel. Email uses wp_mail with text/html. Smoke-tested on testsite: all 12 steps return findings (5/9/4 by level on a fresh local install), admin page renders with all UI markers, HTML report is 26KB, Markdown report is 13KB, prev-session diff banner appears on second session. Deferred: - hc-5ix.27 self-hosted update channel — needs hosting infra. - Full PDF report — would need vendoring Dompdf. - Step 3 safe-mode update wizard — worth its own bead.
