 ## Error and Repair Pipelines

 ### htmx — `#include <htmx.h>`
-Serves the runtime as the `{{> htmx }}` partial; sets `is_htmx` on requests with the `HX-Request` header. Return a fragment to htmx and full page to direct visits via `.if_context`/`.unless_context`. Use `hx-boost='true'` to upgrade links/forms. Put `{{> htmx }}` once in `<head>`.

 ### datastar — `#include <datastar.h>`
-Serves `{{> datastar }}` partial; `datastar_sse()` pushes reactive patches over an SSE channel (page opens a resource `.sse` channel; pipelines push patches). First value (by order) = channel (interpolation ok). Named:
-- `.target` — CSS selector to patch (interpolation ok).
-- `.mode` — `mode_outer mode_inner mode_replace mode_prepend mode_append mode_before mode_after mode_remove`.
-- `.elements` — context key with the rendered HTML fragment (not needed for `mode_remove`).
+Serves `{{> datastar }}` partial; `datastar()` pushes reactive patches over an SSE channel (page opens a resource `.sse` channel; pipelines push patches). First value (by order) = channel (interpolation ok). Named:
+- `.target` — target element to patch, an element id or CSS selector (interpolation ok).
+- `.mode` — `ds_outer ds_inner ds_replace ds_prepend ds_append ds_before ds_after ds_remove`.
+- `.elements` — context key with the rendered HTML fragment (not needed for `ds_remove`).
 - `.signals` — context key with signal state to merge into the client store.
 - `.js` — JavaScript to run on the client.

 ## Safety Guarantees (handled by the framework — do not reimplement)
 
-- Memory: per-request arena allocators; no `malloc`/`free` in app code (use `allocate()`/`defer_free()`). All framework structures bounds-checked; OOB reads / missing keys return `nullptr` rather than faulting. Pipeline memory cap (default 5MB) aborts with 500.

 - SQL injection: `{{interpolation}}` in query SQL is bound as prepared-statement parameters.
 - XSS: `mustache()`/`mdm()` auto-escape; raw HTML requires explicit `{{{field}}}`/`{{&field}}`.
 - CSRF: state-changing requests verified against a per-session token; emit via `{{csrf:input}}` / `{{csrf:param}}`.
