+- `wp_bootstrap_should_render_template` filter in `TemplateController::render()` — allows plugins and child themes to prevent the theme from rendering a specific request, enabling clean separation of concerns when plugins handle their own page rendering

+## [1.0.3] - 2026-02-11
+
+### Fixed
+
+- Double `<h1>` headings on pages where plugins provide their own titles — `page.html.twig` now wraps `<h1>` in `{% if post.title is not empty %}` guard so plugins can suppress it by passing empty `post.title`

 ## Session History
 
+### Session 12 — v1.0.4 Template Render Filter (2026-02-11)
+
+**Completed:** Added `wp_bootstrap_should_render_template` filter to `TemplateController::render()` for clean plugin/theme separation.
+
+**What was added:**
+
+- New `wp_bootstrap_should_render_template` filter at the top of `TemplateController::render()` — returns `true` by default, but plugins can return `false` to prevent the theme from rendering a request
+- Enables the wp-jobroom plugin to handle its own custom post types and routes without the theme's `TemplateController` racing to render first
+- Theme remains 100% standalone — the filter is a no-op when no plugin hooks into it
+
+**Key learnings:**
+
+- WordPress `template_redirect` hook priority ordering is the primary mechanism for plugin/theme rendering coordination: plugin Router at priority 5, theme TemplateController at default priority 10
+- Adding a simple filter check (`apply_filters('wp_bootstrap_should_render_template', true)`) is the cleanest decoupling mechanism — no cross-project class detection needed
+
+### Session 11 — v1.0.3 Conditional Page Title (2026-02-11)
+
+**Completed:** Made `<h1>` on page template conditional to prevent double headings when plugins provide their own titles.
+
+**What was fixed:**
+
+- `views/pages/page.html.twig` now wraps `<h1>{{ post.title }}</h1>` in `{% if post.title is not empty %}` guard
+- When a plugin passes empty `post.title` via `render_via_theme_twig()`, the theme's `<h1>` is skipped
+- Prevents duplicate headings on pages where plugin templates render their own `<h1>` with richer context (icons, badges, meta)
+
+**Key learnings:**
+
+- Plugins that delegate rendering to the parent theme via `TwigService` should be able to opt out of the theme's `<h1>` by passing empty `post.title`
+- The `is not empty` Twig test correctly handles both `null` and empty string `''`
+
 ### Session 10 — v1.0.2 Title Tag Fix (2026-02-10)
 
 **Completed:** Fixed missing HTML `<title>` tag on all pages rendered by the theme's Twig pipeline.

+The `TemplateController` intercepts frontend requests and renders the appropriate Twig template with data gathered by `ContextBuilder`. Plugins can hook into the `wp_bootstrap_should_render_template` filter to prevent rendering for specific requests (e.g., when a plugin handles its own custom post types).
