+# Command system and optional Discord feature
+
+## Purpose
+
+Commands were originally implemented as part of the Discord bot. Web chat support was later added by adapting site chat messages into Discord-shaped messages and reusing the Discord command router. This leaves an important server capability owned by an optional external integration and creates inconsistent behavior between transports.
+
+The command system should instead be an always-available server capability. Web chat and Discord should both be adapters for the same command system, while Discord itself becomes an optional feature that can be disabled without affecting commands or the rest of the server.
+
+This is an internal architecture change. Existing behavior on the outside must remain unchanged unless this plan explicitly introduces a new command.
+
+## Non-negotiable behavior
+
+- Existing command names and syntax continue to work.
+- Existing permission and lockdown rules continue to work.
+- Existing web-chat command messages and replies continue to look and behave the same.
+- Existing Discord replies and embeds retain the same content, titles, field ordering, colors, timestamps, mention behavior, attachment names, progress updates, and edit behavior.
+- Existing Discord chat bridge, presence, moderation workflows, announcements, and other integrations continue to work when Discord is enabled.
+- Disabling Discord does not disable site-chat commands, replay generation, or unrelated server features.
+- Discord.js types, messages, embeds, guilds, channels, and configuration do not leak into the shared command implementation.
+- Replay hosting requires no new configuration. It must be automatic, conservative, and functional.
+- Backwards compatibility for obsolete internal architecture is not required after migration. Temporary migration adapters should be deleted when the new path is complete.
+
+## Target dependency direction
+
+```text
+Web chat adapter ---------+
+                          |
+                          v
+                 Operator command service ----> Existing server services
+                          ^
+                          |
+Optional Discord adapter -+
+```
+
+The operator command service owns parsing, command discovery, permission policy, execution, and neutral results. It does not know how a web-chat message or Discord message is represented.
+
+The name `operatorCommandService` avoids confusion with the existing rover `commandService`, which sends operational commands to individual rovers.
+
+## Command configuration
+
+Command naming belongs to the command system rather than Discord:
+
+```yaml
+commands:
+  prefix: "rs"
+  timeStatusCommand: "ts"
+```
+
+Both web chat and Discord must read these same values. Prefix matching remains case-insensitive and must match a whole token so a prefix such as `rs` does not treat a word such as `rsvp` as a command.
+
+Discord becomes an explicitly optional feature:
+
+```yaml
+discord:
+  enabled: false
+  token: ""
+```
+
+The existing Discord channel, role, site URL, and other settings stay under `discord`. `discord.enabled` is authoritative: a stored token must not silently enable the feature. If Discord is enabled but required credentials are missing or login fails, the failure is clearly logged and must not prevent the rest of the server from operating.
+
+### Existing server feature system is authoritative
+
+Use `server/src/helpers/features.js` as the single source of truth for whether optional features are configured and enabled. Do not add a command-specific feature registry, duplicate configuration checks inside command handlers, or infer availability independently from individual config fields.
+
+- Add Discord to `buildFeatureFlags()` using the same explicit feature-gating pattern as the other optional server features. Discord is enabled only when `discord.enabled` is explicitly true and the required token is present.
+- Discord service bootstrap, command-adapter registration, integrations, presence, bridge behavior, alerts, and Discord replay delivery all consult the shared Discord feature flag.
+- Command definitions use `requiredFeature` metadata, and the command dispatcher resolves that metadata through `isFeatureEnabled()` or a feature-flags snapshot from the same helper.
+- Help availability and command execution use the same feature result so help cannot advertise a command as available when execution considers it disabled.
+- Lift and Neato availability comes from the existing `lift` and `neato` feature flags. Commands must not reproduce their Home Assistant, switch, device, or enabled-field checks.
+- Configuration-level feature availability is separate from runtime health. For example, an enabled lift may currently be disconnected, and configured Discord may fail login. The shared feature helper answers whether the feature is enabled and configured; the owning service remains authoritative for runtime readiness and returns a clear operational failure.
+- Replay generation and automatic local replay hosting are core server capabilities and are not feature-gated. Only the optional Discord delivery provider depends on the Discord feature flag and live Discord readiness.
+
+When Discord is disabled:
+
+- Do not construct a Discord client.
+- Do not attempt login.
+- Do not register Discord event handlers or event-bus integrations.
+- Do not register Discord chat bridge subscriptions.
+- Do not start Discord presence behavior.
+- Keep the shared command service and all site-chat commands active.
+
+## Neutral command request
+
+Every transport converts its native user/message state into one normalized request:
+
+```js
+{
+  text: 'rs lock alpha',
+  source: 'web-chat',
+  actor: {
+    id: 'stable actor id',
+    label: 'display name',
+    role: 'admin',
+    isAdmin: true,
+    isLockdownAdmin: false,
+  },
+  context: {}
+}
+```
+
+The web adapter derives the actor from the authenticated socket, identity, and role services. The Discord adapter derives it from the Discord user and configured administrator mapping. Command handlers consume the normalized actor and never inspect a socket or `message.author`.
+
+Transport-specific context is allowed only for transport-specific extension commands. For example, the Discord-only bridge command needs guild and channel context, but shared commands must not depend on it.
+
+## Command registry
+
+Replace the large dispatcher switch and scattered help definitions with a command registry. A command definition should contain enough metadata to drive parsing, authorization, availability, and help:
+
+```js
+{
+  name: 'lift',
+  category: 'feature',
+  summary: 'Control the rover lift.',
+  description: 'Show lift state or request upward or downward movement.',
+  usage: ['lift status', 'lift up', 'lift down'],
+  examples: ['rs lift status', 'rs lift down'],
+  access: 'admin',
+  lockdownAccess: 'lockdown-admin',
+  requiredFeature: 'lift',
+  execute,
+}
+```
+
+The dispatcher should be responsible for common authorization. Individual handlers may perform finer-grained checks when subcommands truly require different access, but they should not duplicate the ordinary admin and lockdown gates.
+
+## Command categories
+
+Categories organize registration and help. Existing syntax must not be changed merely to add categories; for example, `rs mode` stays `rs mode` rather than becoming `rs admin mode`.
+
+### System commands
+
+General server information and server-wide user actions:
+
+- `rs help`
+- `rs status`
+- `rs replay`
+- The configured time-status command, currently `ts`
+- Future health, session, or informational commands that do not belong to one optional feature
+
+### Admin commands
+
+Operational, access, and moderation controls:
+
+- `rs lock`
+- `rs unlock`
+- `rs mode`
+- `rs kick`
+- `rs goal`
+- `rs reason`
+- `rs verify`
+- `rs deter`
+- `rs lights`
+
+Existing admin and lockdown-admin policies remain authoritative.
+
+### Feature commands
+
+Commands belonging to optional hardware or server features. Initial additions should include:
+
+- `rs lift status`
+- `rs lift up`
+- `rs lift down`
+- `rs neato status`
+- `rs neato start`
+- `rs neato home`
+- `rs neato locate`
+- `rs neato clear-errors`
+
+Feature command handlers must call the existing feature services. They must not reimplement lift interlocks, cooldowns, connectivity checks, Home Assistant calls, Neato state rules, or other hardware safety logic. The feature service remains the source of truth and the command reports its result.
+
+The dispatcher checks each command's `requiredFeature` against the existing server feature system before execution. The owning feature service then performs runtime availability and safety checks. This deliberately keeps configuration eligibility centralized in `helpers/features.js` while keeping live device state and operational rules inside the service that controls the feature.
+
+Commands for an unavailable or disabled feature return a clear unavailable response rather than throwing or silently doing nothing.
+
+### Discord-only commands
+
+Discord bridge configuration is not a general server command. Keep `bridge` as a Discord extension command registered by the Discord adapter:
+
+- `rs bridge`
+- `rs bridge here`
+- `rs bridge mode`
+- `rs bridge off`
+
+These commands retain their current syntax and Discord behavior but do not appear as available commands in web chat.
+
+## Organized help
+
+Help is generated from registry metadata so command definitions and documentation cannot drift apart.
+
+The default help should be detailed but scannable, grouped into System, Admin, and Features. Discord-only commands can appear in a Discord section when help is requested from Discord. Help should respect the configured prefix and time-status command.
+
+Support focused help:
+
+- `rs help system`
+- `rs help admin`
+- `rs help features`
+- `rs help status`
+- `rs help replay`
+- `rs help lift`
+- `rs help neato`
+- The same pattern for every registered command
+
+Focused command help should include:
+
+- A clear description
+- Required permission level
+- Availability or required feature
+- Accepted usage forms
+- Useful examples
+- Subcommand explanations where applicable
+
+The registry provides neutral help data. Web chat renders readable plain text. Discord uses its own renderer and must preserve the established outward style. Improving organization must not accidentally change unrelated Discord embeds such as rover status and time status.
+
+## Neutral command results and transport rendering
+
+Shared handlers return neutral results instead of calling `message.reply()`:
+
+```js
+{
+  handled: true,
+  ok: true,
+  messages: [
+    {
+      kind: 'text',
+      text: 'Locked Alpha.',
+    },
+  ],
+}
+```
+
+Simple commands should return text results. Structured results should be used only where transports benefit from different faithful presentations, such as rover status, time status, help, administrative lists, or replay progress.
+
+Discord renderers translate neutral results into the same Discord.js reply and embed objects used today. Existing embed builders should be extracted and retained where possible instead of visually rewriting them during this architecture change.
+
+The web adapter translates the same results into the existing `Rover bot` system messages. The current behavior where the user's command remains visible in the chat transcript should remain unchanged.
+
+## Replay architecture
+
+Replay generation and replay delivery are separate responsibilities:
+
+```text
+Replay request
+    |
+    v
+Replay engine builds one completed MP4
+    |
+    v
+Replay delivery coordinator
+    |-- Discord is enabled, ready, and replay channel works
+    |      -> upload MP4 to Discord
+    |      -> use returned Discord attachment URL
+    |
+    `-- Discord unavailable, unconfigured, or upload fails
+           -> store MP4 under the server data directory
+           -> use server-hosted media URL
+    |
+    v
+Publish the playable replay media payload to clients
+```
+
+Discord remains the preferred host when it is configured for replay delivery. A Discord upload failure after a successful replay build must fall back to local hosting instead of failing the replay. The Discord failure should be logged clearly, while clients still receive a working replay.
+
+The common client media payload should remain compatible with the current payload so `/mini`, `/display`, spectator clients, and other replay consumers behave the same. Discord-specific metadata remains present when Discord hosted the media. Locally hosted media supplies the same common playable URL and media fields without pretending to be a Discord attachment.
+
+### Automatic local replay hosting
+
+No replay-hosting configuration is added. Use conservative internal constants chosen after checking typical generated replay sizes.
+
+The local media service should:
+
+- Store completed files in `data/replays/` through the canonical data-directory helper.
+- Use random, non-guessable IDs in public filenames.
+- Expose a deliberate route such as `/media/replays/:id.mp4` rather than placing runtime media in built web assets.
+- Support HTTP range requests so browsers can seek and play MP4 files normally.
+- Set the correct media type and safe cache headers.
+- Write atomically by completing a temporary file and renaming it into place.
+- Never expose or delete a file that is still being written.
+- Remove abandoned temporary files.
+- Delete expired replay files during server startup.
+- Run one lightweight periodic cleanup while the server is running.
+- Stop the cleanup timer during graceful shutdown if the server has a shutdown lifecycle.
+- Enforce both a conservative age limit and a conservative total storage ceiling.
+- Delete the oldest completed files first when the storage ceiling is exceeded.
+- Treat cleanup errors as logged, nonfatal maintenance failures.
+- Prevent path traversal and serve only known replay filenames from the replay directory.
+
+Cleanup must operate only on the hosted replay directory and must not touch replay frame caches, unrelated data files, or active replay builds.
+
+## Optional Discord feature boundary
+
+The Discord feature owns:
+
+- Discord client creation and login
+- Intents and partials
+- Discord message-to-command adaptation
+- Neutral-result-to-Discord rendering
+- Existing embed presentation
+- Discord replay upload delivery
+- Chat bridge and webhook behavior
+- Guild bridge storage and bridge commands
+- Presence
+- Discord announcements and alerts
+- DM verification and private-access moderation workflows
+- Reactions and Discord event handling
+
+Discord must be added to and activated through the existing server feature system. The Discord entrypoint must not maintain a separate interpretation of `discord.enabled` and token availability. Runtime client readiness may still be tracked inside the Discord feature for operations such as replay upload, but that readiness supplements rather than replaces the shared configuration feature flag.
+
+The Discord feature may import the operator command service. The operator command service, replay engine, chat service, and feature command handlers must not import the Discord feature or Discord.js.
+
+## Focused regression protection
+
+The existing implementation is the reference for current command wording and behavior. Read and preserve that behavior while moving each handler; do not first catalogue every reply or build exhaustive snapshots for all commands.
+
+Use focused tests and practical checks at the boundaries most likely to cause meaningful regressions:
+
+- Discord status and time-status embeds retain their existing content, structure, colors, field order, timestamps, and links.
+- Discord replay progress edits, attachment upload, filename, URL extraction, and client media publication continue to work.
+- A failed or unavailable Discord replay delivery falls back to working locally hosted media.
+- Commands remain operational when Discord is disabled or fails login.
+- Web chat and Discord use the same configured prefix and whole-token matching behavior.
+- Admin and lockdown permissions are enforced consistently from both transports.
+- Disabled feature commands return a clear unavailable result, while enabled feature commands use their owning service's runtime safety checks.
+- Hosted replay routes support playback and seeking, reject invalid paths, and cleanup only expired completed media.
+
+Use direct inspection and practical command checks for ordinary response wording. Additional tests are appropriate when complex logic is extracted, but exhaustive output transcription is not a prerequisite for the refactor.
+
+## Implementation sequence
+
+Build directly toward the final architecture. It is acceptable to move commands in logical groups while working, but avoid investing in a durable old/new compatibility framework. Once a replacement path works, remove the obsolete adapter and duplicated implementation.
+
+1. Add the operator command request, actor, result, parser, registry, authorization, and help foundations.
+2. Extract existing Discord formatting and embed construction into transport-owned renderers without changing their output.
+3. Move existing system and admin commands into the registry, using their current code as the behavioral reference.
+4. Move status and time status while separating neutral data collection from unchanged Discord embed rendering.
+5. Add organized registry-driven help with transport-specific output.
+6. Add lift and Neato feature command families using the existing feature flags, services, and safety rules.
+7. Add the automatic local replay media store, HTTP route, range serving, startup cleanup, periodic cleanup, and storage limits.
+8. Split replay generation from delivery and add the Discord-preferred/local-fallback delivery coordinator.
+9. Move replay onto the shared command service while preserving existing Discord progress and upload behavior.
+10. Convert web chat and Discord to the shared command service and move bridge commands into the Discord-only extension registry.
+11. Add Discord to the existing feature system and gate all Discord bootstrap and integrations through it.
+12. Remove the Discord-owned shared router, fake Discord message objects, web replay command injection, result-flattening workaround, and duplicate replay paths.
+13. Add or update focused tests for the high-risk boundaries listed above.
+14. Run server tests, practical command checks, the web UI build, and targeted lint for touched files.
+
+## Completion criteria
+
+- The server has one transport-neutral command registry and execution path.
+- Web chat commands work with Discord completely disabled.
+- Discord consumes the shared command service as an optional adapter.
+- The configured command prefix behaves consistently everywhere.
+- Help is organized by System, Admin, Features, and Discord-only extensions where applicable.
+- Detailed per-command and per-category help is available.
+- Lift and Neato commands use existing service safety and availability behavior.
+- Discord-hosted replays behave exactly as before when Discord delivery succeeds.
+- Replays automatically fall back to maintained server-hosted media without configuration.
+- Existing clients continue receiving compatible replay media payloads.
+- Existing Discord embeds and outward behavior remain unchanged.
+- Temporary adapters and duplicated command logic are removed.

+# the inter-instance API and system
+A single API endpoint that returns one json object with information about this instance of this server, meant to display on other servers.
+A centralized json file pulled from a simple link on the internet which contains a list of public server instances
+Basically, designed so that everyone's rover servers can show on everyone else's rover servers in some way.
+In the end once its all working, users will be able to see rovers from other instances on any other instance, click on a rover, and just via a simple href with a few URL params, it will put you on that instance, that rover, and transfer your cookie object through a URL parameter.
+
+## centralized json file of public instances
+- contains a list of simple URLs, like:
+```["https://rover.otter.land"], ["http://14.84.27.47:8080]```
+- all servers will use the same link to the same json file by default (this will be to a file on github or something)
+- there is an option for multiple links, for redundancy. but it only comes with one in the config.
+- this should be ONLY a list of links, maybe with placeholder names to show in the UI if one of them is offline
+- if my server had the two example links above, it would contact both info API endpoints from both of those separate instances for information about them.
+- if a new server is to be added, add it to the centralized json file and that instance will show on all other instances, and it will show all other instances on itself.
+
+## the general concept of the inter-instance API system
+- every server hosts the same API endpoint which returns one big json object for that instance
+- every server automatically gets the list of instances from the centralized json file
+- every server automatically requests all of the other inter-instance information from all the other servers
+- every server will show the info from all the other servers on it's web UI.
+
+## what information will the servers get from the other servers?
+- servers will get a bunch of info from the other servers which they poll the APIs of
+- this information will, for the most part, just be sent straight to the web UI where most of the data moving will happen
+- at least these things will need to be communicated
+  - is the server open? (turns/open access mode)
+  - server name
+  - server color for UI
+  - non-optional description
+  - an object of rovers containing, for each rover,
+    - rover name
+    - rover battery level
+    - any users on it?
+    - rover color
+    - rover description
+    - locked?
+    - locked reason
+    - basically, all the info that the webui uses now to show a rover in the rover roster
+  - maybe an object containing feature states, from the system of features.js in the server, so people can see what features that instance does and doesn't have
+  - MAYBE could even have images that are derived from that instance's URL that the web UI can use to show room cameras if they exist or rover snapshots
+
+## what will this look like in the web UI?
+- a button at the bottom of the rover roster that says show external rovers or something
+  - when you hit this button it shows the external rovers in the same roster stuff as the local instance rovres
+  - when this is expanded theres a button to open the shared inter-instance component in a popup
+- a new component, a cardframe, which will be a component shared in multiple spots. contains:
+  - the instances
+    - the instance info, name, description, etc
+    - the rovers in the instances and their statuses
+    - the features that the instance has
+- ALSO show this same cardframe on the admin lock overlay, so people can see other instances while their current one is locked
+- all new UI has to be mobile friendly.
+
+
+## switching to a different instance from a previous one
+- users should be able to click on a rover from the listing of another instance, and be put on that rover on that instance.
+  - this should just be a thing that takes you to a new link to the new instance, with a couple of URL params.
+- when switching, have a URL param for the rover that theyre requesting, 
+  - this URL param should just make the web UI automatically request the rover from the param.
+- and another URL param, which:
+  - takes their ENTIRE identity / settings cookie over to the new instance, by encoding the json in base64 in the URL. 
+    - when the web UI takes this URL in, it should replace the cookie with the one from the URL. maybe with a popup first that asks to transfer your identity from previous instance to the new one?

+# ONVIF first, reolink specifics second PTZ camera integration
+
+## what where who how
+- adding support for a reolink PTZ camera
+- ideally control everything over ONVIF
+  - if needed for some of the special features, use https://github.com/verheesj/reolink-api
+- VIP (verified user) feature only
+- due to upload bandwidth limitations (ONLY UPLOAD TO USERS MATTERS HERE NOT INTERNAl NETWORK STUFF), only one person should be on the camera at a time. only one person at a time should view 
+  - the ptz camera should have a queue and turns that are like 5 mintues long or so, so no one can hog it
+  - if you are the camera operator, you are not on a rover. ever.
+  - if you are a spectator, you can see the snapshots for it
+    - local spectators should get full video like they already do now though
+- the camera needs to be a replay source
+- camera video needs to go through the same pipeline as rover video does and get to the client over webRTC
+
+## camera learnings
+- scan for all onvif features that the camera has
+
+## UI flow:
+- whole UI should be very technical and utilitarian
+  - use cardframe for everything
+  - match global styling
+- new card in VIP tab
+  - shows whoevers on the camera
+  - a very slow snapshot of the camera view
+  - maybe some other stats
+  - a big button to open the camera controller
+- the fullscreen camera interface
+  - the rest of the site needs to go away when this is open
+  - when its open, it takes over your rover controls. whatever they are
+    - easy route for this could be to intercept it right before the control goes to the server, so any control gets converted to a ptz control
+  - desktop
+    - movement controls pan and tilt
+    - camera up / down controls zoom
+    - headlight and laser buttons hopefully control spotlight and IR light or something
+    - fullscreen inteface
+    - right sidebar with info and controls info
+  - mobile
+    - uhhh idk
+    - obviously, camera on the screen
+    - probably add a variant of the mobile controls just to retitle the things from the rover controls to the camera controls
+    - and just use the same control columns
+
+-- slop generated below --
+
+## clarified implementation direction
+
+This is not intended to become a generic ONVIF camera framework. The camera integration is for one specific Reolink PTZ camera. Once the camera arrives, we will run a one-time ONVIF capability discovery against that exact camera, record what it exposes, and then build the integration around those known capabilities.
+
+The one-time discovery should capture:
+- ONVIF services exposed by the camera
+- media profiles and stream URIs
+- snapshot URI support
+- PTZ support and movement modes
+- pan/tilt/zoom ranges and speed ranges
+- preset/home support
+- imaging controls
+- any ONVIF-exposed spotlight, IR, or night-vision controls
+- whether PTZ status reporting is reliable
+
+After that, runtime code should assume this known camera profile instead of trying to dynamically support every possible ONVIF camera.
+
+## claiming and operator rules
+
+The PTZ camera is a single scarce controllable resource.
+
+Only verified/VIP users can claim it during normal operation. Only one user can operate it at a time. The active operator gets live WebRTC video and PTZ control for a limited turn, probably around five minutes. Other remote users should only receive slow snapshots. Local spectators may be allowed live video because LAN traffic is not the bandwidth problem.
+
+A user operating the PTZ camera must not also be operating a rover. When a user tries to move from a rover to PTZ, the existing rover-switch safety rule should be reused: switching is allowed if another driver remains on that rover, or if the current rover is docked and charging. Otherwise, the server should block the PTZ handoff and tell the user to dock and charge their rover first.
+
+This should be implemented by refactoring the existing rover switching check into a shared helper, such as `canLeaveCurrentRover(socket)`, then using that helper from both rover switching and PTZ claiming.
+
+## streaming model
+
+Camera video should come from the Reolink camera over the local network, likely RTSP into MediaMTX. Browser playback should use the existing MediaMTX WHEP/WebRTC pipeline.
+
+The existing video session and MediaMTX auth system should be extended with a `ptz` source type. Remote live WHEP access should be allowed for the current PTZ operator, local spectators, and authorized admins according to normal server rules. Remote non-operators should not get live video.
+
+Slow snapshots should use a PTZ-specific snapshot path or socket gateway, modeled after the existing room camera snapshot system, but with PTZ-specific authorization rules.
+
+## lockdown behavior
+
+No extra UI work is needed for lockdown because the app already visually blocks things in lockdown mode.
+
+Server-side lockdown enforcement is still required everywhere. In lockdown mode, only lockdown admins/users may claim, queue, operate, subscribe to snapshots, request live PTZ video, or use PTZ replay sources. If lockdown starts while a normal user is operating PTZ, the server should immediately revoke their operator state, remove them from the PTZ queue if needed, revoke PTZ video sessions, and stop accepting PTZ commands from them.
+
+## reusable existing systems
+
+Strong reuse targets:
+- rover switch safety logic from `roverManager/roverLifecycle.js`
+- `videoSessions`
+- `videoSocketService`
+- `videoAuthService`
+- `WhepPlayer`
+- `sessionService` session sync
+- VIP panel/card structure
+- alert system
+- replay source validation and replay worker architecture
+
+Adapted reuse targets:
+- turn queue/timer structure from `turnService`
+- turn alert listener behavior
+- room camera snapshot socket/feed pattern
+- `RoomCameraFeed` for slow preview display
+- replay source catalog and ffmpeg workers
+- existing control input concepts, but with a PTZ-specific command pipeline
+
+Do not directly merge PTZ into `roomCameraService` or `commandService`. PTZ should have its own service boundary because it has ownership, queueing, ONVIF control, video authorization, and camera-specific state.
+
+## operator UI and controls
+
+The VIP tab should get a PTZ camera card. The card should be technical/utilitarian and match the existing site style. It should show:
+- current camera operator
+- queue/turn state
+- turn time remaining when relevant
+- whether the current user can claim or must wait
+- whether the current user must dock and charge before switching
+- a slow snapshot preview
+- a button to open the fullscreen PTZ controller when the user is the active operator
+
+The fullscreen PTZ controller should take over the whole app surface while open. It should not feel like a normal side panel. When active, the user is in camera-operation mode, not rover-driving mode.
+
+Desktop controls:
+- movement input pans and tilts the camera
+- camera up/down or equivalent camera tilt controls zoom in/out
+- available special controls expose only what the one-time ONVIF probe proved exists
+- if ONVIF exposes presets/home, provide those controls
+- if ONVIF exposes spotlight, IR, or night mode, provide those controls
+- if those features are not exposed through ONVIF, leave them out until a Reolink-specific fallback is intentionally added
+- include a compact right-side status/control panel with operator, queue, camera state, and available controls
+
+Mobile controls:
+- reuse the existing mobile control layout concept where practical
+- relabel/re-map rover movement controls for PTZ movement
+- keep the camera view as the main screen
+- use the existing mobile control columns/pads as inspiration, but send PTZ commands instead of rover commands
+
+Input/control implementation:
+- do not send PTZ through the existing rover `commandService`
+- create PTZ-specific socket events/handlers owned by the PTZ camera service
+- use a PTZ-specific client command pipeline that maps existing input intent into PTZ commands
+- server must enforce that only the active PTZ operator can send movement/zoom/control commands
+- client-side input interception is only for UX; server-side operator checks are the real authority
+- all movement controls should send stop commands on key/button release, blur, disconnect, controller close, or turn loss
+
+## NEW UI STUFF
+- desktop:
+  - sidebar like there is now
+  - replay panel in sidebar
+  - better indicators of light and OR modes
+  - list of controls using keybind things
+- mobile:
+  - one sidebar on the right
+  - reuse rover drive control panel for camera movement
+  - reuse gpio toggle buttons for spotlight and IR
+  - reuse camera tilt slider for zoom
+  - relabeled variants where needed for reused mobile controls
+  - scroll sidebar down to see replay panel
+- both:
+  - the VIP panel
+    - sucks. 
+    - wasted space
+      - put snapshot and everything else side by side
+    - add a display of ptz's turn queue
+    - camera should open when you request control over it. no need to have it be another button to press
+    - should show state of camera
+  - the fullscreen interface
+    - should be inside a cardframe, with no title bar
+    - reuse anything whereever possible
+    - needs to be ACTUALLY FULLSCREEN, not with space around the edges anywhere
+    - needs to match the global styling, and use cardframes internally for stuff.
