"""Session 76: Performance, scale, error recovery, and edge cases in Catholic usage contexts.

12 scenarios testing mmap memory behavior, bulk search, Strong's chaining,
MCP tool chains, network failure degradation, canon boundaries, reference
parsing disambiguation, translation comparisons, reading-plan integrity,
index rebuild reliability, and multi-module stress loading.

Scenarios:
  S1  — Full Tobit Retrieval with Verse-Level Strong's (mmap flat heap)
  S2  — Search 60 Commentaries + 31 Lexicons for "mercy" at Scale
  S3  — Bulk Strong's Lookup for All Unique Words in Judith 16
  S4  — 10-Tool MCP Chain: Eucharistic Discourse (John 6:53-58)
  S5  — Network Failure Graceful Degradation
  S6  — Canon Boundary Exhaustive: All Deuterocanonical Books
  S7  — Catholic Reference Parsing: Aliases + Comma-Skip Combinations
  S8  — Search Edge Cases: Greek + Multi-Word Catholic Phrases
  S9  — 10+ Translation Comparison: 2 Maccabees 12:44-46
  S10 — Catholic 358-Day Reading Plan Full Integrity
  S11 — Index Rebuild + Immediate Unicode Search
  S12 — Simultaneous 10-Module Load Stress
