Types

type Counter 

type Counter struct {
	// contains filtered or unexported fields
}

Counter atomically admits and releases concurrent resources such as Edge or browser WebSocket connections. A release function is idempotent.

func NewCounter 

func NewCounter() *Counter

func (*Counter) Acquire 

func (c *Counter) Acquire(tenant string, resource Resource, limit int) (release func(), err error)

func (*Counter) Usage 

func (c *Counter) Usage(tenant string, resource Resource) int

type Policy 

type Policy struct {
	Retention RetentionDays
	Quotas    Quotas
}

Policy is the resolved policy used by runtime enforcement.

func Defaults 

func Defaults() Policy

Defaults returns the fail-safe v0.1 policy.

func (Policy) Limit 

func (p Policy) Limit(resource Resource) (int, error)

Limit returns the resolved limit for resource.

func (Policy) Validate 

func (p Policy) Validate() error

Validate rejects unlimited, negative, or unreasonably large settings.

type QuotaError 

type QuotaError struct {
	Tenant   string
	Resource Resource
	Limit    int
	Usage    int
}

QuotaError carries only non-sensitive usage facts.

func (*QuotaError) Code 

func (e *QuotaError) Code() string

func (*QuotaError) Error 

func (e *QuotaError) Error() string

func (*QuotaError) Unwrap 

func (e *QuotaError) Unwrap() error

type Quotas 

type Quotas struct {
	Devices         int
	Edges           int
	BrowserWS       int
	Tokens          int
	Users           int
	EventsPerMinute int
	PluginInstances int
}

Quotas contains resolved hard limits. Zero/unlimited is deliberately invalid.

type Resource 

type Resource string

Resource is a stable machine identifier used by HTTP error codes and audit. 

const (
	ResourceDevices         Resource = "devices"
	ResourceEdges           Resource = "edges"
	ResourceBrowserWS       Resource = "browser_ws"
	ResourceTokens          Resource = "tokens"
	ResourceUsers           Resource = "users"
	ResourceEventsPerMin    Resource = "events_per_min"
	ResourcePluginInstances Resource = "plugin_instances"
)

type RetentionDays 

type RetentionDays struct {
	Events             int
	TerminalCommands   int
	Audit              int
	RevokedTokens      int
	PluginObservations int
}

RetentionDays contains resolved, non-null retention values.

type WindowLimiter 

type WindowLimiter struct {
	// contains filtered or unexported fields
}

WindowLimiter is an in-memory fixed-window limiter for high-rate resources such as events. It is tenant/resource scoped and uses an injectable clock.

func NewWindowLimiter 

func NewWindowLimiter(window time.Duration, now func() time.Time) *WindowLimiter

func (*WindowLimiter) Allow 

func (l *WindowLimiter) Allow(tenant string, resource Resource, limit int) error
