Summary

#45 made the code compatible with the strict Agda flag set. This PR declares the flags in the files. --cubical-compatible is coinfective: a module that declares it may only import modules that also declare it. So choreographic-types cannot adopt the strict set while the epistemic-types modules it imports lack the flag.

• All 22 source modules and all 13 rejection fixtures: the OPTIONS pragma gains --cubical-compatible --exact-split --no-sized-types --no-guardedness, keeping --safe --without-K.
• tests/check-proofs.sh and tests/check-rejections.sh: both now also pass -W noUnsupportedIndexedMatch.
  • Under --cubical-compatible, Agda emits an UnsupportedIndexedMatch warning at 23 clauses that match on indexed constructors. It means those functions would not compute on Cubical transports.
  • That is irrelevant under --without-K. The estate strict set silences it, as agda-stdlib's own library file does.
  • Both scripts run with -W error, so without the flag the warning would be fatal.

• tests/integration/CanonicalEcho.agda is unchanged. It imports echo-types at pin 46cd1a3, whose modules do not yet declare the flag. A file without the flag may still import ones that have it, so it keeps building. Add the flag after the pin moves to an echo-types commit that carries proofs: declare the strict flag set in every module that can take it echo-types#357's change.

Verification (Agda 2.6.3 locally; CI checks the pinned 2.6.4.3)

• tests/check-proofs.sh: PASS, 22 source modules.
• tests/check-rejections.sh: PASS, all 13 rejected for the expected type mismatch.
• CanonicalEcho.agda, built against echo-types 46cd1a3 exactly as the workflow does: compiles.

📝 Summary

Summary by CodeRabbit

• Chores
  • Updated proof modules and validation checks to use consistent Agda compiler settings.
  • Adjusted warning handling in the proof and rejection checks.

Production modules and rejection fixtures add Agda compiler options for cubical compatibility, exact splitting, and disabling sized types and guardedness. Test commands disable the UnsupportedIndexedMatch warning.

Changes: Agda compiler option alignment

Layer / File(s)	Summary
Production module options src/EpistemicTypes/*.agda, src/EpistemicTypes/Applications/*.agda, src/EpistemicTypes/Kripke/*.agda	Production module option pragmas add --cubical-compatible, --exact-split, --no-sized-types and --no-guardedness. Existing --safe and --without-K options remain enabled.
Test commands and rejection fixtures tests/check-proofs.sh, tests/check-rejections.sh, tests/reject/*.agda	The test commands disable the UnsupportedIndexedMatch warning. Rejection fixtures add the new module options.

Merge Risk: Low · up to c9ab6

The proof gates may accept code with unsupported Cubical transport computation; keep the suppression scoped to the canonical integration.
