Struct Trajectory 

pub struct Trajectory {
    pub id: String,
    pub target_findings: Vec<String>,
    pub deposited_by: String,
    pub created: String,
    pub steps: Vec<TrajectoryStep>,
    pub notes: String,
    pub review_state: Option<ReviewState>,
    pub retracted: bool,
    pub access_tier: AccessTier,
}

Fields

id: String

vtr_<16hex>, content-addressed at creation.

target_findings: Vec<String>

vf_* findings this trajectory describes the search for. May be empty when the trajectory leads nowhere yet — the search can be deposited before its target finding exists.

deposited_by: String

Stable actor id of the depositor (the lab / curator / agent that opens the trajectory).

created: String

RFC 3339 creation timestamp (also folded into the id).

steps: Vec<TrajectoryStep>

Append-only ordered list of steps. Reproduced by replay from trajectory.step_appended events.

notes: String

Free-text reviewer note on the trajectory as a whole.

review_state: Option<ReviewState>

Optional review verdict — same ReviewState enum the rest of the kernel uses.

retracted: bool

True once a trajectory.retracted event has been applied.

access_tier: AccessTier

v0.51: Read-side access tier. See FindingBundle.access_tier for the doctrine. Search paths can be especially sensitive when they document protocols that capability-gate downstream; the substrate accommodates this through the same tier machinery as findings and nulls.

Implementations

impl Trajectory

pub fn content_address( target_findings: &[String], deposited_by: &str, created: &str, ) -> String

Compute the content-addressed trajectory id per v0.50 spec: SHA-256(target_findings.join(",") | deposited_by | created). Returns first 16 hex chars prefixed with “vtr_”.

Note: target_findings is sorted before concatenation so the id is stable under permutations of an unordered input set. Steps are NOT folded into the id — they’re append-only and would otherwise force a new id every append.

pub fn new( target_findings: Vec<String>, deposited_by: impl Into<String>, notes: impl Into<String>, ) -> Self

Construct a new Trajectory with a freshly-derived id and empty steps. Steps are appended via trajectory.step_appended events through the reducer.

Trait Implementations

impl Clone for Trajectory

fn clone(&self) -> Trajectory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Trajectory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Trajectory

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Trajectory

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
