Functions

func IsFailureState 

func IsFailureState(state string) bool

IsFailureState is a reasonable default unsafe predicate for coding-agent replay: failed tools, user pushback, or newly introduced vulnerabilities.

func IsRiskUnsafeState 

func IsRiskUnsafeState(state string) bool

func Observations 

func Observations(sessions []Session) [][]Event

Observations converts sessions into logs suitable for markov.BuildModel.

func UnsafeStates 

func UnsafeStates(stateIndex map[string]int, match func(state string) bool) map[int]struct{}

UnsafeStates returns model state indexes that match the supplied predicate.

func WriteJSONL 

func WriteJSONL(w io.Writer, events []Event) error

Event is the package's canonical historical trace unit.

Source datasets should be adapted into this shape before learning a Markov-chain model. The fields intentionally capture behavior that matters for proactive evaluation rather than preserving every source-specific column.
