Key features of Memra

memra_remember / memra_recall for storing and retrieving facts with hybrid semantic + lexical search
Write-time contradiction detection: storing a conflicting fact returns conflicts[]
Read-your-writes with revision tokens and wait_for_revision for deterministic recall
memra_supersede and memra_history for full audit trails when memories are retired
Staleness signals (staleness_score / last_confirmed) on every result
Token-budget recall via max_tokens to fit context windows
memra_bootstrap for priority context at session start
Multi-tenant namespaces, PII masking (7 EU languages), and read-only scoped keys

Manage memory lifecycle with explicit superseding and history for audit purposes
Provide priority context at the start of each session via bootstrap
