Struct ObservationResult 

pub struct ObservationResult {
    pub k: u64,
    pub residual_norm: f32,
    pub sign: SignTuple,
    pub grammar: GrammarState,
    pub motif: MotifClass,
    pub semantic: SemanticDisposition,
    pub dsa_score: f32,
    pub policy: PolicyDecision,
    pub lyapunov: LyapunovResult,
    pub sub_threshold: bool,
    pub suppressed: bool,
}

Full deterministic trace for one observation — the audit chain.

Every field in this struct corresponds to a stage in the DSFB pipeline. The complete chain can be serialized to dsfb_traceability.json by the output module (requires serde feature).

Fields

k: u64

Observation index k.

residual_norm: f32

Raw residual norm ‖r(k)‖.

sign: SignTuple

Sign tuple σ(k) = (‖r‖, ṙ, r̈). Stage 1 output.

grammar: GrammarState

Grammar state after hysteresis. Stage 2 output.

motif: MotifClass

Motif class from syntax layer. Stage 3 output.

semantic: SemanticDisposition

Semantic disposition from heuristics bank. Stage 4 output.

dsa_score: f32

DSA score. Stage 5 output.

policy: PolicyDecision

Final policy decision. Stage 6 output.

lyapunov: LyapunovResult

Lyapunov stability result: finite-time Lyapunov exponent λ(k), stability classification, and estimated time-to-envelope-exit.

sub_threshold: bool

Sub-threshold flag (SNR < floor → drift/slew forced to zero).

suppressed: bool

Suppressed flag (waveform transition → grammar forced to Admissible).
