Unrecoverable FC2 Activation-Residual Source

No exact FC2 activation-residual or residual-gate epilogue kernel source exists in the worktree diff, untracked files, reachable history, reflogs, or dangling objects. Current prose specifies the required BF16 operation order and identifies FC2 Stream-K behavior as a future target, but that is design evidence rather than recoverable implementation.
