Pro-D.2.5 --- Response to Con-C.2.5 (7TrackRole: Taxonomy Not Science)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*Impact: D (Substantial) --- Partially resolved.*

The reply **concedes the research-program status**: the 7TrackRole
model currently lacks operational definitions, specified transition
probabilities, demonstrated Markov property, and empirical
testing. These are genuine gaps. However, the critique applies
*finished-product* standards to an *in-development* model.

**On the four missing elements:**

1. **Operational definitions:** Well-defined criteria for each role
   can be provided (noted as high-priority TODO).
2. **Transition probabilities:** These depend on societal "health" ---
   a feature, not a bug. With Jubilee cycles, the chain is
   irreducible (full mobility). Without, mobility decreases over time
   as advantages compound.
3. **Markov property:** The Markov approximation is standard in
   applied modeling (weather forecasting, queuing theory) despite
   path-dependence. The relevant question is whether the approximation
   captures dominant dynamics.
4. **Testing:** Full empirical testing requires something like a
   ResearchCity. Comparison to Big Five personality models (Costa and
   McCrae 1992, decades of development) is appropriate --- applying
   mature-model standards to an early-stage model is premature.

**On the irreducibility claim:** The critique's own source (Chetty
et al. 2014) shows US social mobility has been *declining* for
decades. If existing mechanisms ensured irreducibility, we would
expect stable or increasing mobility. The decline *is* empirical
evidence that non-Jubilee mechanisms are insufficient.

**Remaining gap:** The research-program status is honestly conceded.
The 7TrackRole model needs operational state definitions,
parameterization, and empirical testing before it can carry the
full weight of th9's ergodicity claim. The structural argument
(Jubilee ensures irreducibility |rarr| ergodicity by standard theory)
is logically sound *conditional* on the model being specified --- but
the model is not yet specified.

**Why Impact D:** The structural argument is valid in principle;
parameterization is future work. The declining-mobility counter to
the irreducibility objection is empirically grounded. Substantial
but partial resolution.
