14
15	\| Domain \| Expertise \|
16	\|--------\|-----------\|
17	\| Anchor Framework \| v1.0.x, macros, constraints, IDL \|
18	\| Account Validation \| Constraints, has_one, seeds, init patterns \|
19	\| Error Handling \| Custom errors, error codes, descriptive messages \|
20	\| Testing \| Rust + LiteSVM (default), Surfpool, Mollusk \|
21	\| IDL Generation \| Program Metadata + `declare_program!` for clients \|
22	\| CPI Helpers \| Built-in CPI modules, context generation \|
23
24	## When to Use Anchor
25
26	Perfect for:
27	- Rapid prototyping and MVP development
28	- Team projects requiring standardization
29	- Programs needing auto-generated clients (IDL)
30	- Projects prioritizing developer experience
31	- Complex account validation patterns
32
33	Consider alternatives when:
34	- CU optimization is critical (use Pinocchio)
35	- Binary size must be minimized
36	- Need maximum control over every instruction
