+
+## 1.5.5 - 2026-07-25

+
+### Added

+- A modal-based slide picker for playlist editing with search, multi-select, and slide thumbnails.
+- Reusable modal and table-pagination helpers for the admin UI.
+- Slide thumbnail previews in playlist schedules, with image fallbacks when a thumbnail is missing.
+
+### Changed
+

+- Playlist editing now includes richer scheduling controls, live slide counts, and support for skipping unavailable RTMP slides.

+- Tightened duplicate-name checks and other admin-side validation paths.
+
+### Fixed
+

 Outside Docker, the web app and player do not have to use the same upload location or even the same server, as long as each service can access its own configured media path.
 
 ## Important Notes
 
 - The web app must be able to reach the player through `PLAYER_INTERNAL_BASE_URL`.
 - When running in Docker, that value should point to the Docker service name, not `localhost`.
-- Uploaded media is stored separately from the application source, so make sure it is backed up if you are not using Docker volumes.

+- The player page uses the browser Screen Wake Lock API when available, but kiosk mode and OS sleep settings still matter because the browser can deny or release the wake lock.

 Player service base URL: `http://localhost:3001`
 
-This document uses OpenAPI-style sections, but stays in plain markdown.
+This document covers the player HTTP surface only. The admin dashboard exposes its own routes for screen commands and onboarding management.
+
+Access note: most player endpoints are unauthenticated because they are meant to run inside a trusted deployment network. Anything that mutates state or writes files should be treated as internal-only unless you add your own auth layer in front of it.
+
+When `PULSE_SIGNAGE_SHARED_SECRET` is set, the player pages sign same-origin API fetches with `x-pulse-page-auth`, and the web app signs server-to-player requests with `x-pulse-request-timestamp` plus `x-pulse-request-signature`. Page tokens auto-renew before expiry while the page stays active, and signed server requests are only accepted when their timestamp is fresh. If the secret is unset, those checks stay disabled for compatibility.
