NASA RW / Group trajectory signatures

Individual signatures are read above group trajectory, not as standalone health labels.

The randomized-workload substrate supports a clear distinction: trajectory-level co-drift can be shown, pair-level coupling is not resolved, and RW12 is a single-cell cross-projection survivor above its group trajectory.

Claim boundary. Raw values preserved in native units; reference-cycle and random-window features keep their own clocks. Observation layer only: not SOH, RUL, safety, fault, remaining-life, warranty, underwriting, mechanism, or investment advice.

What can be shown

Three visual layers.

Trajectory level

Co-drift discipline

Matched random-window and reference-cycle deviation series can be shown as monotone biography trajectories under the audited wording; that wording names the exceptions (one cell’s random-window lens is flat).

Null

No pair-level coupling resolved

Trend-partialled pair-level coupling is a powered null; do not upgrade co-movement into coupling.

Individual

RW12 signature above group

RW12 carries a cross-projection individual signature above its group trajectory (paraphrase; the canonical wording lives in the audited sheet). It remains a single-cell freeze, not a class claim.

Figures

Existing source figures.

NASA RW path-C cross-projection figure — Path-C figure supporting the cross-projection signature lens; the figure predates the final audit, and verdicts follow the audited sheet.

NASA RW v2 figure — v2 figure retained as context for co-drift and null development.
