Discuss this taskWhat is needed to advance this task?
There is an effective-equation target for a free longitudinal mode; detector coupling and signal strength remain undetermined.
Derive a response function from perturbation to measurable frequency or length and construct a noise budget.
Source and detector models, transfer function, polarization or direction features, sensitivity and systematics.
01Why the problem matters
Find a response distinguishable from thermal noise, acoustic disturbance and electromagnetic cross-talk.
02Known structure and progress
There is an effective-equation target for a free longitudinal mode; detector coupling and signal strength remain undetermined.
03Research task
Derive a response function from perturbation to measurable frequency or length and construct a noise budget.
04Deliverables
Source and detector models, transfer function, polarization or direction features, sensitivity and systematics.
05Routes to avoid
Absence of dissipation implies neither absence of geometric spreading nor unlimited penetration or an available communication technology.

07Space Dynamics v1.0 handoff
The formal OP-SD task develops this guide's research direction with existing derivations, missing work and reviewable deliverables. The earlier entrance is retained. Current continuum definitions and candidate status follow the Space Dynamics module.
