ecta-identification
Use when the bottleneck is identification and inference for an Econometrica manuscript — identification conditions and asymptotic distribution theory for an estimator, or axioms and existence/uniqueness for a theory model. Stress-tests the formal foundations before the proofs and simulations are written.

# Identification, Asymptotics, and Axiomatic Foundations (ecta-identification)
## When to trigger
- An estimator is defined and shown consistent, but its **limiting distribution** is missing
- Identification is asserted ("the parameter is identified") without a proof or counterexample analysis
- A theory model posits behavior but the **axioms** are not isolated, or existence/uniqueness is unproven
- Inference is proposed (standard errors, tests) without the asymptotic theory that justifies it
This is the formal spine. Econometrica referees check it first; a gap here sinks the paper.
**Re-slant for Econometrica.** Identification here is *not* primarily "do I have a credible
research design for a causal estimate" (that framing belongs to AER / QJE / JPE / REStud).
Econometrica's core is **identification and estimator validity inside structural and
