"""Session 76 tests: CLI and REST API coverage in Catholic usage contexts.

Covers 12 scenarios spanning CLI subcommands and REST API endpoints:
  - S1: Catholic Reading Plan Traversal with Deuterocanonical Day Retrieval
  - S2: Canon-Boundary API Error Chain
  - S3: CLI Error Paths for Deuterocanonical Out-of-Bounds References
  - S4: Acc2 Harmony via REST API
  - S5: Morphology Pipeline Cross-Testament
  - S6: Search → Lexicon → Verse Chain (REST)
  - S7: CLI study → interlinear → verse with NABRE
  - S8: REST Lectionary → Verse Range → Interlinear for Epiphany
  - S9: Canon Resolve Latin Names + Books Enumeration
  - S10: REST Search with Type/Language Filters
  - S11: Module Registry → Health → Index Status
  - S12: CLI lexicon Unicode → REST lookup with summary levels

All tests use skipIf to guard missing dependencies (CLI binary, FastAPI app,
network connectivity). Subprocess tests use generous timeouts for module
loading overhead.
