~anthropic/claude-sonnet-latest → A (6:4)

Side A fixes a concrete production bug (silent fallback to a blocked public Reddit endpoint), adds real retry-on-401/403 logic with tests, and improves error diagnostics — a focused, verifiable improvement. Side B is a large DSL syntax reshuffle (moving explanations before votes) whose diff is dominated by mechanical test/fixture rewrites across many files, which is churn-heavy relative to the core logic change in dsl.rs and lacks the same clear bugfix payoff for users in production today.
