Vivado 26.1 still doesn't understand `view`s, or at least `converse`

Description
@nathanaelhuffman I think we'd found this somewhere else prior and thought it was supposedly fixed? I found this while updating my own system from 2024.1 to 2026.1 today. While building cosmo_seq:
stderr:
ERROR: [Synth 8-10561] cannot update object 'ready' of mode 'in' [/home/aaron/Oxide/git/quartz/hdl/ip/vhd/sha3/sha3_256.vhd:164]
ERROR: [Synth 8-12189] Failed to read vhdl '/home/aaron/Oxide/git/quartz/hdl/ip/vhd/sha3/sha3_256.vhd'
ERROR: [Common 17-69] Command failed: Synthesis failed - please see the console or run log file for details

Research direction
Reproduce the cosmo_seq build with Vivado 26.1 and start at hdl/ip/vhd/sha3/sha3_256.vhd:164, where synthesis reports the failure. Compare how the view or converse construct is handled during VHDL synthesis. Done means the design builds without the reported Vivado errors.
