Summary

Documents the challenge token construction version (v: 1), the Argon2id salt entropy fix, and the clarification that both argonProfile tiers currently share the same tuning.

Changes

  • Added the v field to the challenge token payload table and explained fail-closed behavior for unknown versions
  • Updated the invalid-token warning reason to cover unknown construction versions
  • Clarified that 'mobile' and 'standard' Argon2id profiles currently resolve to the same parameters, and why picking a tier now is safe
  • Added an Argon2id non-goals warning (it raises attack cost, it is not human verification)
  • Added a v0.2.6 changelog entry

Context

Ribaunt v0.2.6 strengthens challenge entropy to 16 random bytes, embeds a v: 1 construction version in every token so future changes cannot break in-flight tokens, and keeps legacy tokens verifying. Both Argon2id profile tiers intentionally share the same conservative tuning for now.
