control_wrap() puts a register file in front of any self-describing core — but the traffic is one-way: configuration in, nothing back. Cores already carry state worth reading — the bayerlink receiver's sticky overflow flag, frame counters — and today that state exists as wires with nowhere to go. A Reg(source=...) should bind a core output to a read-only register, with sticky/clear semantics declared rather than hand-wired.
Done means: an example where a core sets a sticky flag, the host reads it over AXI4-Lite, the clear semantics behave as declared, and the register map documents it like any config register.
What it unlocks downstream: bring-up that reads answers instead of guessing — did pixels arrive, did the FIFO overflow, how many frames passed — which is the first thing anyone asks of new hardware.
This is a sponsorable capability target (see the README's funding section). Sponsored work lands in the open tree immediately, MIT like everything else — sponsorship buys ordering and named credit, not exclusivity. Scope by email: s.rabykin@gmail.com.
