identity

func BuildCanonicalID ¶

func BuildCanonicalID(platform, platformID string) string

BuildCanonicalID constructs a canonical "platform:id" identifier. Both platform and platformID are lowercased and trimmed.

func MatchAllowed ¶

func MatchAllowed(sender bus.SenderInfo, allowed string) bool

MatchAllowed checks whether the given sender matches a single allow-list entry. It is backward-compatible with all legacy formats:

• "123456" → matches sender.PlatformID
• "@alice" → matches sender.Username
• "123456|alice" → matches PlatformID or Username
• "telegram:123456" → exact match on sender.CanonicalID

func ParseCanonicalID ¶

func ParseCanonicalID(canonical string) (platform, id string, ok bool)

ParseCanonicalID splits a canonical ID ("platform:id") into its parts. Returns ok=false if the input does not contain a colon separator.
