Given the time, the string likely decodes to something like {"deep_link":"...","maker_auto":true} or similar, with feature as a clue to extract a flag.

Let's step back.

I notice cm1ha2Vy is part of the string. cm1ha2Vy in Base64 decodes to "rmaker" ? Actually: cm1ha2Vy → base64 decode: c=0x63, r=0x72, m=0x6d, a=0x61, h=0x68, 2=0x32, V=0x56, y=0x79 → no, that doesn't work because 2 is not valid base64 char unless it's part of cm1h (c r m h? Wait, let’s do properly). Given the time, the string likely decodes to

Instead, let's try: URL-decode %3D is = , but here no % signs. Could this be a misinterpretation? Possibly not.

Given the puzzle nature, and your — feature instruction, the likely intended answer is:

The string length and structure strongly suggests . Reason: jt and ji appear often — these are %7B and %7D in URL encoding if we map jt → %7B ? Not exactly. But jt could be %7B if j = %7 and t = B ? No. Base64 length should be multiple of 4

Actually, let me do a direct base64 decode using known tools in mind: I can’t run code here, but pattern cm1ha2Vy appears again in middle: cm1ha2Vy = base64 of rmaher ? That’s nonsense. So maybe cm1ha2Vy is cmF + something? No.

Another thought: jtdc might be { in some encoding?

Let me try the whole string:

Better: take the string as a whole — but first, does it contain % signs? No, it’s plain text. But %3D would be = . If it's double-encoded, %25 is % . So %3D becomes = in first decode.

But cm1ha2Vy — that is rmaker only if it's cmFrZXI= (maker) — wait cmFrZXI= is maker in base64. Yes: cmFrZXI= base64 → maker . So cm1ha2Vy with 1 instead of F ? No, cmFrZXI= has Fr not 1h .

The string you provided appears to be encoded or obfuscated. Let me analyze it step by step. cm1ha2Vy in Base64 decodes to "rmaker"
