Struct ShardContext 

pub struct ShardContext {
    pub entity_code: String,
    pub entity_seed: [u8; 32],
    pub extra_journal_entries: Vec<JournalEntry>,
    pub opening_balances: Vec<EntityOpeningBalance>,
}

Context for shard-mode generation.

When EnhancedOrchestrator.shard_context == None (the default), the orchestrator behaves byte-for-byte like the pre-v5.0 single-entity flow. When Some(ShardContext { extra_journal_entries, .. }), those JEs are appended to Phase 4’s accumulator just before the post-journal-entries resource check.

Fields

entity_code: String

This shard’s entity code. Informational in v5.0 (the orchestrator already carries the entity via GeneratorConfig); future phases may use it for routing or logging.

entity_seed: [u8; 32]

32-byte per-entity seed from manifest.ownership_graph.entities[i].entity_seed. Informational in v5.0.

extra_journal_entries: Vec<JournalEntry>

IC journal entries pre-built by the shard runner before calling EnhancedOrchestrator.generate(). Appended to the JE accumulator at the end of phase 4.

opening_balances: Vec<EntityOpeningBalance>

v5.3 — Opening-balance carryover from a prior period. When non-empty, the orchestrator’s Phase 3b (opening balances) replaces its generated openings with these carryover values for this entity, seeding period-N+1 from period-N’s closing TB instead of generating a fresh opening from the industry-mix generator.

Empty by default — engagements that don’t supply a prior period (the v5.0–v5.2 default) see no behaviour change: the orchestrator generates openings via OpeningBalanceGenerator as before.

Callers prepare these by reading the prior period’s per-entity period_close/trial_balances.json and projecting onto BS-only positions via datasynth_group::aggregate::extract_opening_balances.
