Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 12]

▼Naiming
CAimCommand	Result of one policy update. For Aim and Home, angles is the new target pose. For Hold, angles is the current commanded pose (the last Aim or Home, or the Home pose before any lock); consumers act only on Aim and Home
CAimMap	Pan = pan_a * x + pan_b, tilt = tilt_a * y + tilt_b
CAimPolicy
CAngles	Turret pose: pan degrees from home (positive = right), tilt servo degrees (larger = up)
CButtonClassifier
CButtonConfig
CCalibrationSession
CCalPoint	One calibration sample: the target's pixel and the turret angles that pointed at it
CPixel	An image position in pixels; not clamped, so it can lie outside the frame
CPlannerConfig
CPolicyConfig
CReachBox	Rectangle of frame pixels (inclusive corners) with x0 <= x1 and y0 <= y1
CStepPlanner
CTrackView
▼Ncontrol
CControlLogic	The control loop's decisions, one pass per run() call: button gestures, HUD requests, the three modes and the status counters
CControlPorts	Everything ControlLogic reads from or commands on the device, called from the loop task
CHudRequests	The HUD's one-shot requests, taken from the inbox together once per pass
CLogRecord	One log event and its arguments; fields other than the event's own are left at their defaults
CStickDeflection	Joystick deflection per axis, -255..255 (Joystick::get_speed_x / get_speed_y); y positive = up
▼Nframes
CFrameLease	Move-only handle on a published frame. Releases its slot exactly once, on release() or destruction
CFrameMeta
CFrameSlots
CReadyList	Fixed-capacity result so the stream path never allocates per frame
CSlotReleaser	Whatever a FrameLease must notify when it is released (FrameSlots natively, FrameStore on device)
CViewerSet
▼Nhud
CHomeState	AI return-home state read from the aiming::AimPolicy. Ignored unless ai_mode is set
CReplyInput	Inputs of one reply. Null pointers mean that part is not available
▼Nprov
CAction
CCandidates	Saved networks present in a scan, strongest first
CNetworkEntry	One saved network. Strings are NUL-terminated
CNetworkList	Up to kMaxNetworks saved networks; the least recently added or joined one is evicted when full
CPinGuard	Guards the PIN. The 5th consecutive wrong PIN starts a lockout of min(60 s * 2^k, 3600 s), k = lockouts since the last success; the failure count then resets. Lockout state lives in RAM only
CPinRecord	Salted PIN hash as stored in NVS
CPinResult
CScanResult	One access point seen by a scan
CWifiPlan	Decides what the WiFi glue should do next. Events that do not apply to the current state return Action{None} and change nothing. All time arithmetic is wrap-safe
▼Nremote
CAimPixel	Image pixel requested by an Aim command
CBaseRemoteSink	Receives parsed commands; implemented by the controller (device) and fakes (tests)
CCommand	One parsed message. Only the fields matching kind are meaningful
CJog	Jog request in the same units as Joystick/Turret::jog
CRemoteInbox	Stores the latest Move (with timeout), the jog speed and the pending mode, calibration and aim requests
▼Nstats
CWindowedCounter	Remembers the previous reading of a free-running unsigned counter; sample() returns the delta since
▼Ntelemetry
CSources	The objects the stats lines read. All references must outlive the program (they are globals)
▼Ntracking
CBlob	One connected region of foreground cells
CBox	Inclusive cell rectangle. A default-constructed box is empty
CDetectionResult	What the detector found in one frame. Blobs are sorted by area, largest first
CDetectorConfig	Motion detector tunables. Defaults are tuned for an indoor scene 1-3 m away
CMotionDetector
CTracker
CTrackerConfig	Tracker tunables (frame counts assume ~17 fps)
CTrackState	The tracked target. Positions in cells, velocity in cells per frame. id 0 = no target
▼Nvsync
CMutexLock	Scoped lock on a FreeRTOS mutex; takes it forever on construction and gives it back on destruction
CSpinGuarded	A value of type T that owns its own spinlock; every access is one short critical section
CBaseDetectionModule	An abstract base class (Interface) that defines the contract for detection algorithms. This class allows the Controller to remain agnostic of the specific detection method (e.g., Color, AI, or Motion) by providing a consistent interface
CBaseStatusProvider	Interface for anything that can report a ControlStatus (the Controller). Lets the network layer read state without depending on the Controller
CBaseTurret
CCamera	Camera setup and sensor tuning
Ccamera_buffer_t
CCameraDiffDetection	Motion detection and persistent single-target tracking on camera frames
CCameraTaskStats
CCommandsWebSocketHandler	The /commands WebSocket: parses each HUD message, hands it to the remote sink and replies with JSON metrics
CController	Runs the control loop on the device: the clock, the HUD inbox, NVS, logging and the published status around the pure control::ControlLogic
CControlStatus	Snapshot of the controller, published once per control pass
CDetectionStats
CFrameStore
CFrameStoreStats
CHttpServer	Manages the ESP32-CAM web interface and control API
CJoystick	High-level interface for 12-bit analog joystick input
CMoveDirection	Base template providing common logic for movement directions
CMoveX	Encapsulates horizontal movement states and utility methods
CMoveY	Encapsulates vertical movement states and utility methods
▼CStreamBroadcaster
CSendStats	How long frame sends block the httpd task (every /stream send runs on it, and so does /commands)
CTestDetection
CTrackSnapshot
CTurret	Non-blocking turret: callers post commands, a 1 kHz motor task executes them
▼CWifiManager	Glue between the pure prov::WifiPlan and the Arduino WiFi stack
COutcome	Outcome with the lockout time for Result::LockedOut
CStatus	Snapshot for /api/wifi/status
CWifiStore	Reads and writes the `wifi` NVS namespace (keys `nets`, `pin`, `appw`) using the pure blob formats
