TSMM Maturity Model

TSMM can model systems that are incomplete, emerging, or experimental. Inclusion in TSMM means a system is structurally analyzable within the meta-model. It does not by itself imply production readiness, normative endorsement, or cross-ecosystem maturity.

This maturity model is the repo-wide taxonomy for bindings, crosswalks, and other comparison surfaces that need a governance signal.

Maturity states

Status Meaning Typical use
experimental Modeled for analysis, comparison, and early testing Early-stage or still-evolving ecosystems that are worth comparing without overstating maturity
candidate Structurally coherent and ready for broader ecosystem review Comparison surfaces likely to stabilize soon but not yet treated as fully settled
supported Stable enough for normal TSMM comparison use Published and maintained comparison surfaces suitable for routine use
deprecated Retained for reference, not recommended for new work Historical or superseded surfaces kept to preserve traceability

Stability states

Stability Meaning
draft Early or provisional documentation and machine-readable mapping
review Ready for wider review but still open to material change
stable Expected to change only in bounded and traceable ways
sunset Being retained for continuity while active use winds down

Production recommendation values

Value Meaning
not-yet Do not treat inclusion as a production-readiness signal
conditional Use only with explicit caveats and composition requirements
yes Normal comparison use is fine within the stated scope
no-new-adoption Keep for reference, but do not expand new usage

How to apply this taxonomy

AIS-1 now

AIS-1 is currently treated as experimental in TSMM. That means it is useful to model and compare as a bonded identity and accountability substrate, but TSMM is not claiming that AIS-1 is already a mature or complete trust-stack profile.
