Module event 

Zero-allocation event emission via sol_log_data.

Events are emitted as raw Pod bytes through the sol_log_data syscall. This is ~100 CU and zero-allocation. For unforgeable events, use emit_event_cpi which self-invokes the current program (~1000 CU).

Dual emission model

Function	CU Cost	Spoofable?	Use case
emit_event	~100	Yes (any program can log)	Fast indexer events
emit_event_cpi	~1000	No (verified via self-CPI)	Trustworthy audit trail

Functions

emit_event

Emit a Pod event via sol_log_data.

emit_event_cpi

Emit an unforgeable event via self-CPI (~1000 CU).

emit_event_tagged

Emit event with a discriminator prefix for easy client-side filtering.

emit_slices

Emit one or more byte slices as a single sol_log_data entry.
