Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
This "evasion-to-solution" framework highlights how innovations such as dual-antigen CARs, low-affinity designs, NK-specific signaling, iPSC-derived NK platforms, and multiplex gene editing directly mitigate known mechanisms that lead to therapeutic failure.

Operational role: regulator. Implementation mode: genetically encoded. Cofactor status: cofactor requirement unknown.
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.

Compared with CAR-NK cells
low-affinity designs and CAR-NK cells address a similar problem space because they share editing, signaling.
Shared frame: same top-level item type; shared target processes: editing, signaling
Relative tradeoffs: appears more independently replicated; looks easier to implement in practice.
