Module generation_session 

Models for the unified generation pipeline’s session state.

These types track the state of a multi-period generation run, including fiscal period decomposition, balance carry-forward, document ID sequencing, and deterministic seed advancement.

Structs

BalanceState

GL and sub-ledger balances carried forward between periods.

DocumentIdState

Sequential document-ID counters so IDs never collide across periods.

EntityCounts

Counts of master-data entities generated so far.

GenerationPeriod

A single period within a generation run.

PeriodLog

Summary of what was generated in a single period.

SessionState

Accumulated state for a multi-period generation session.

Functions

add_months

Add months calendar months to a NaiveDate, clamping the day to the last valid day of the target month.

advance_seed

Derive a deterministic per-period RNG seed from the master seed.
