… guard Closes LabsCrypt#421 — stream_count() -> u64 - Add stream_count() read-only function that returns the global StreamCounter value (monotonically increasing, equals the highest stream ID ever issued, never decrements on cancel/complete). - Returns 0 on a freshly-deployed contract with no streams. - Add TypeScript binding fetchStreamCount() in frontend/src/lib/soroban.ts that simulates the view call without wallet auth. - Unit tests: stream_count_returns_zero_on_fresh_contract, stream_count_increments_by_one_per_create, stream_count_is_not_decremented_by_cancel, stream_count_matches_last_stream_id. Closes LabsCrypt#787 — resume_stream status guard - resume_stream now checks stream.status == Paused (not just stream.paused), so a stream cancelled while paused (status=Cancelled, paused=true) correctly returns StreamInactive instead of being resurrected to Active. - cancel_stream now explicitly clears stream.paused = false and stream.paused_at = None when settling a cancellation, ensuring no stale pause state survives into the Cancelled record. - Unit tests: resume_after_cancel_while_paused_returns_stream_inactive, cancel_while_paused_clears_pause_fields, cancel_normal_stream_also_clears_pause_fields.
…tream The pause state clearance (paused=false, paused_at=None) was placed after the CEI-refactored save_stream call, putting it inside the interactions block where token_client/contract_address are in scope but stream state mutations should not happen. Move the two lines up into the effects block, before save_stream, consistent with the existing is_active/status/last_update_time assignments.
