Space-Time and the Speed of Light
Introduce the relationship between spatial extension, temporal order, and the limiting speed. Use it as a bridge between the original cosmological discussion and later DTT reconstruction work.

Connecting generated geometry with relativity
A causal cone, a material clock, and a symmetry of physical observers are related but distinct structures. The relativity programme asks how one source could generate their agreement, while keeping each quantity independently measurable throughout the reconstruction.
A finite update can supply a propagation bound, and suitable geometric assumptions can express that bound through a Lorentzian form. Further calibration is needed to select a metric scale, while physical clock and transport laws determine whether real apparatus realizes the corresponding transformations. Mathematical cone symmetry alone does not establish that operational agreement.
The clock studies make this issue concrete. A protected readout can ignore branching, while an ungated clock can respond to the same work differently. Both can accompany one record geometry. The central challenge is therefore a source-derived selection principle that removes this freedom and connects matter propagation, clock readings, and observer transformations.
Limiting speed
Distinguish a finite-update bound, a band group velocity, and a physical signal cone before asking whether the same source fixes their shared conversion.
Clock selection
Explore exact and finite-calibration criteria for resolution-only clocks, together with countermodels showing why one realizable clock does not prove physical universality.
Lorentzian reconstruction
Follow cone geometry, conformal calibration, and physical boost realization as separate steps toward a common account of spacetime and material observers.
