Identifies repeated storage reads

Recommends single storage read

Identifies stored computed value

Recommends lazy evaluation

Identifies O(n) vector lookup

Recommends Table for O(1) lookup

Identifies large event structs

Recommends minimal event data

Does NOT remove security checks

Table replaces vector listings

O(1) lookup in find_listing

Bitwise flags replace bool fields

Named flag constants defined

Consolidated storage reads

Redundant listing_fee field removed

Stored total_value_locked removed or lazily computed

Reduced event struct size

Security checks preserved

Appropriate integer types

Table/SmartTable for stakers

No vector linear lookup

Lazy reward calculation

Struct fields use small integer types

Bitwise flags for state

Minimal event data

Single storage read per function

Security checks NOT removed

gas_notes.md documents costs

Early return in validation
