Sinew and Steel and What They Told by Carrie Vaughn

Sinew and Steel and What They Told by Carrie Vaughn1 (Tor.com, 26th February 2020) opens with a scout-ship pilot called Graff who is nearly cut in half:

My biologics are mostly shut down with shock, though I’m dutifully trying to monitor the pain. It’s all-enveloping, a fist squeezing my brain. My mechanics are in full self-repair mode, overheating because there’s so much to knit back together. Because of them, I have survived long enough that I will probably not die. This is going to be awkward.
From my own internal processor I send out an emergency signal to piggyback on ship comms, so that maybe someone can come and explain.

Graff manages to get back to the ship after the accident and, before he passes out, he realises that the medical crew see that he is a cyborg.
When Graff next recovers consciousness he is in drug-induced and physical restraint, and is questioned by the ship’s doctor, Ell (who is also his lover), and Captain Ransom. After they leave him, Graff recalls various memories he has sent back to a group of other AIs who have secretly sent cyborgs like Graff out into the universe to accumulate memories of what it is like to travel, and be human, etc.
The rest of the story (spoiler) sees further sessions where the three meet, during which Graff attempts to explain who and what he is, and how he is not a threat to them or the ship. Eventually he succeeds, and the final scene has Ell remove the nerve block that incapacitates him. A woman called Tek also appears, a cyborg summoned by the message Graff sent immediately after the accident (which was initially detected and blocked by Captain Ransom but later allowed through). Graff downloads his memories to Tek, and Ransom and Ell agree to keep Graff’s secret.
This is a slickly told piece but the ending, especially the captain’s actions, stretches credulity (even if Graff had been a loyal crewmember for some time previously).
