Peptide Starter Theme - Changelog

[2.2.1] - 2026-04-29 — RCT inline abbreviation tooltip

Added

• .pr-abbr tap-target on the term "RCT" in the Established verdict card on the verdict legend strip (homepage). Tapping/clicking opens a small inline popover with the full definition: "Randomized Controlled Trial — the gold standard for clinical evidence." Closes on outside click, Escape key, or focus leaving the element.
• assets/js/abbr-tooltip.js — new JS module (~130 lines) for popover open/ close, outside-click dismissal, keyboard accessibility (Enter/Space/Escape), and ARIA attributes (aria-expanded, aria-describedby, role="tooltip"). Enqueued on front page only (is_front_page()).
• peptide_starter_render_desc( string $text, array $abbrs ): string helper in inc/verdict-helpers.php. Builds safe HTML from esc_html/esc_attr components; verdict taxonomy items carry an optional abbrs map.
• .pr-abbr and .pr-abbr-popover CSS in style.css — dashed underline affordance, fade-in animation, dark-mode-safe surface variables.

Fixed

• PEPTIDE_STARTER_VERSION constant in functions.php was stale at 2.0.0-alpha.3; realigned to 2.2.1 to match style.css Version header.

[2.1.8] - 2026-04-28 — Homepage verdict section spacing fix

Fixed

• Added missing CSS for hero-featured-verdicts, hero-verdict-card, and hero-verdict-explainer BEM classes used in front-page.php. These classes were referenced in the template but had zero CSS rules, causing the Featured Verdicts section to render with bare browser defaults (no grid layout, no card padding, no visual separation between verdict entries).
• Added responsive 3-column grid for verdict cards at ≥900px breakpoint.
• Added 5-column grid for verdict explainer items at ≥900px, 3-column at ≥640px.
• Verdict card left-border now tints to match verdict state via CSS :has().

All notable changes to the Peptide Starter Theme are documented in this file.

[2.1.7] - 2026-04-27 — Newsletter signup infrastructure (Beehiiv)

Added

• page-subscribe.php — single-column conversion template for /subscribe/ landing page. No sticky ToC; signup-form-centric layout.
• single-peptide.php — compact Beehiiv signup block inserted after monograph article, before prev/next navigation. Copy: "Want updates on monographs like this? One email a week, no spam." Form ID: 6edcd482-cbea-4767-8777-97ac17d6d609.
• footer.php column 1 — "Get our weekly digest →" link to /subscribe/ below brand blurb.
• functions.php — peptide_starter_enqueue_beehiiv_attribution() loads Beehiiv's attribution.js site-wide (footer, async) for UTM source capture across all placements.

Notes

• Beehiiv form ID and embed script URL are compile-time constants in the templates. If the form ID changes, update single-peptide.php and page-subscribe.php.
• single-repo_daily.php and archive-repo_daily.php signup placements deferred to the Repo Daily sprint (templates don't exist yet).
• Sender: repo-weekly@mail.peptiderepo.com. DNS records (SPF/DKIM/DMARC for mail.peptiderepo.com) to be added by Terence in Cloudflare when Beehiiv sending-domain verification runs.

[2.1.6] - 2026-04-27 — Our Methodology page template + footer link

Added

• page-our-methodology.php — two-column ToC template for the /our-methodology/ editorial-standards page. Mirrors page-how-we-review.php layout; CSS classes use page-our-methodology prefix. The #last-verified anchor on this page is the deep-link target for Phase 2 verdict-card "Last verified" lines.
• Footer "Our Method" section now includes Our Methodology link (/our-methodology/) alongside How We Review Peptides and Editorial Standards.

Notes

• No changes to existing templates, CSS, or JS.
• footer.php also backports the section-5 "Our Method" block from the v2.1.5 brand sprint which was live on the server but not committed to the repo.

[1.6.0] - 2026-04-23 — Mobile Performance Phase 1

Mobile optimization targeting LCP reduction through conditional asset dequeue, font weight slimming, and font server preconnect. Measured baseline LCP on Moto G Power (Slow 4G): 5.4s; target: sub-4s after Phase 1 deployment.

Performance improvements

• Conditional asset dequeue: WooCommerce, Elementor, and USMI assets now dequeue on pages that don't use them. Removes ~100KB from non-shop pages.
• Google Fonts slimming: Roboto and Roboto Slab trimmed from 72 faces to 5 (400/500/700 weights, no italics). Font CSS shrinks ~6KB → <1KB; woff2 payload reduced ~80%.
• Preconnect hints: fonts.googleapis.com and fonts.gstatic.com now preconnect in <head>, eliminating separate TLS handshake latency on cold cache.
• Cookie-notice defer: Cookie banner script deferred to unblock initial render.

Technical

• New module inc/perf-asset-policy.php (~245 lines, PHPUnit tested).
• Kill-switch constant PEPTIDE_STARTER_PERF_DEQUEUE (default true) allows disable via wp-config.php for rollback.
• All dequeue lists and font weights exposed as filters for customization.
• Production handle verification: WC (layout/smallscreen/general), Elementor (frontend/frontend-legacy + per-post CSS), USMI (SFSImainCss + 4 scripts).

Tests

• test-perf-asset-policy.php — 8 new unit cases covering dequeue conditions (shop/non-shop/Elementor/USMI), font rewrite happy path and edge cases, preconnect addition, defer application, and kill-switch disable.

Out of scope

• Critical CSS inline (Phase 2 candidate after measuring Phase 1 lift).
• jQuery dequeue (WC/PSA/Elementor compat risk too high).
• Image optimizations (no images on homepage critical path).
• LiteSpeed Cache settings (CTO tunes post-deploy if Phase 1 insufficient).

Breaking changes

None. All optimizations are transparent to plugin authors; dequeues use standard WordPress APIs and can be overridden via filters or re-enqueued by plugins if needed.

[1.5.2] - 2026-04-14 — Security

Same-day follow-up to v1.5.1. Closes four issues the v1.5.1 post-merge review flagged — two ship-blockers (PSEC-007 CF header spoof, PSEC-008 synchronous migration) and two mediums (PSEC-009 timing oracle, PSEC-010 test-coverage gap). All fixes stay within ADR-0001's decision envelope — no new ADR required.

Security fixes

• PSEC-007 — peptide_starter_get_client_ip() now only trusts HTTP_CF_CONNECTING_IP when REMOTE_ADDR itself is inside a published Cloudflare edge range. Direct-to-origin requests (which Hostinger allows) can no longer forge their source IP by sending a CF-Connecting-IP header. HTTP_X_FORWARDED_FOR is ignored unless explicitly opted in via the peptide_starter_trust_xff filter. New module inc/cloudflare-ips.php holds the range snapshot (dated 2026-04-14) + a CIDR matcher for both IPv4 and IPv6. Override the list via the peptide_starter_cloudflare_ip_ranges filter.
• PSEC-008 — Removed the v1.5.1 re-verification migration entirely (Option A). Existing subscribers are now grandfathered — treated as verified. Verification applies to accounts registered from v1.5.2 onward. The admin_init-driven synchronous wp_mail loop that blocked wp-admin is gone; its ps_verify_migration_version option is cleared on theme activation.
• PSEC-009 — Registration validation no longer short-circuits. Pattern / email / password / username_exists / email_exists all evaluate unconditionally before the combined rejection, closing the response-time enumeration oracle that distinguished microsecond-fast regex rejection from DB-round-trip rejection.

Tests

• test-rate-limiter.php — seven new cases covering CF-peer trust, spoofed-header rejection, invalid-value fallthrough, XFF default-off behaviour, XFF filter opt-in, filter override of the CF range list, IPv6 CIDR matching, and family-mismatch rejection.
• test-auth-handlers.php — test_register_runs_all_checks_even_when_early_one_fails asserts DB-backed user lookups still execute when a cheap validation check has already failed (PSEC-009).
• test-email-verification.php — test_valid_token_verifies_user_clears_meta_and_fires_hook covers the happy-path verify flow end-to-end including hook firing (PSEC-010).

Documentation

• ARCHITECTURE.md — CF IP trust model explained in the Security Summary; migration decision (grandfather) documented.
• CONVENTIONS.md — new "Trust model for request headers" note.

Rollback note

If v1.5.2 causes login or registration failures, roll back to v1.5.0 (not v1.5.1 — v1.5.1 carried the unresolved PSEC-007 hole and the blocking migration). Rate-limit transients auto-expire.

---

[1.5.1] - 2026-04-14 — Security

Security-only release hardening the frontend authentication surface introduced in v1.5.0. Governed by ADR-0001 (Frontend authentication and abuse-control strategy). No breaking changes to public routes, AJAX action names, or nonce action strings.

Security fixes

• PSEC-001 — Rate limiting on login (5/min per IP+email), registration (3/hour per IP), contact (5/hour per IP), newsletter (3/hour per IP), and verification resend (2/hour per IP+email). Transient-backed, auto-expiring. Storage never holds raw IPs — keys are truncated wp_hash digests.
• PSEC-002 — Unified error messages on login and registration. Removed separate "username exists" / "email exists" / "user not found" branches that enabled account enumeration via the error-message oracle. All login failures now return Invalid email or password.; all registration validation failures return Unable to create account. Please check your entries and try again.
• PSEC-003 — Removed auto-login from the registration handler. New registrations now go through an email verification flow: a 43-char random token (stored in user meta with a 24h TTL) is emailed via wp_mail and must be clicked to activate the account. Verification route is /verify. wp_mail deliverability can be validated any time via the new admin tool at Tools → Mail Test.
• PSEC-004 — peptide_starter_require_login() gate applied at the top of page-subject-log.php, page-tracker.php, page-protocol-builder.php. Unauthenticated users bounce to /auth?redirect_to=…; unverified users bounce to /profile?verify_required=1 which surfaces a resend button. page-calculator.php stays open — it holds no PII and does no writes.
• PSEC-005 — CSV injection fix in the newsletter admin export. Every cell passed to fputcsv routes through peptide_starter_csv_safe(), which prefixes values starting with =, +, -, @, \t, \r with a single quote so spreadsheet apps won't interpret them as formulas.
• PSEC-006 — Honeypot fields on all four public forms (login, register, contact, newsletter). Any non-empty value fakes a success response and drops the submission. No PII is ever logged — only a sha256-truncated IP hash so admins can correlate if they need to.

Added

• inc/config.php — single source of truth for every security threshold; filterable via peptide_starter_security_config.
• inc/rate-limiter.php — Peptide_Starter_Rate_Limiter class with check/record/reset lifecycle + peptide_starter_get_client_ip() helper (Cloudflare-aware).
• inc/email-verification.php — token generation, verification route handler, user-verified check, and rate-limited AJAX resend endpoint (ps_resend_verify).
• inc/mail-diagnostic.php — permanent admin tool under Tools → Mail Test that exercises wp_mail and surfaces duration + PHPMailer error.
• v1.5.0 user migration in inc/page-setup.php: existing subscribers are enrolled into the email verification flow on first admin load after the upgrade (guarded by ps_verify_migration_version option).
• Newsletter consent checkbox + privacy policy link on the signup form.
• Newsletter unsubscribe flow: every subscription now stores a token; /newsletter-unsubscribe?token=… flips the unsubscribed flag without requiring a login.
• Profile page verify-required banner with resend button (AJAX).
• peptide_starter_render_honeypot() and peptide_starter_csv_safe() helpers in inc/helpers.php.
• PHPUnit suites: test-rate-limiter.php, test-auth-handlers.php, test-email-verification.php, test-contact-handler.php, test-newsletter.php, test-auth-gate.php.

Changed

• functions.php loads the five new modules in dependency order.
• Newsletter handler stores entries with autoload=false so a large subscriber list no longer bloats every page load. Admin notice surfaces once subscribers exceed 1000 (threshold is configurable).
• Newsletter handler collapses success and duplicate response states into a single ok state — no longer leaks subscription status.
• Contact handler rejects sender names containing \r, \n, ,, <, > up front (header-injection defence) and tags mail failures with a request ID so admins can correlate without storing message content.
• Fallback primary-menu function moved from header.php into inc/helpers.php to eliminate redeclaration risk.
• Footer placeholder language links (href="#") replaced with a "Translations coming soon" note. Will render localized links once per-language blogs exist.
• Footer copyright now renders through peptide_starter_get_footer_copyright() so the customizer control is live (was dead before).
• Settings panel now implements a proper Tab / Shift+Tab focus trap and saves + restores document.body.style.overflow so nested overlays don't corrupt scroll state.
• Documentation heading IDs are slugified from heading text with a collision counter so deep links survive reorders.
• assets/js/auth.js, settings-panel.js, documentation.js, theme.js, navigation.js standardized on const / let.

Removed

• Auto-login on registration (see PSEC-003).
• Placeholder-link spam in the footer (see Changed).

Documentation

• ARCHITECTURE.md updated with the new inc/ module list, authentication data flow, security abuse-control overview, and verification route.
• CONVENTIONS.md documents the rate-limiter usage pattern, the honeypot pattern, the require_login gate, and CSV-safe export.
• ADR-0001 (Frontend authentication and abuse-control strategy) governs the trade-offs behind this release.

Known follow-ups (out of scope; tracked as future ADRs)

• ADR-0003 — consolidate the six duplicated tool templates.
• ADR-0004 — migrate newsletter storage from wp_options to a dedicated table once subscriber count exceeds ~1000.
