HTTP response framing incomplete

Vibe & agenticNetworking & APIsAlgorithms & data structuresSenior~20 min

An AI wrote this Python code to read an HTTP response off a raw socket for a lightweight client. It works against curl-friendly servers. Explain the framing bug, when bodies come back wrong, and the fix.

Implement
bytes_still_to_read(headers: list[str], buffered: int) → int
Examples
in[["Content-Length: 120","Content-Type: application/json"],40]out80
in[["Transfer-Encoding: chunked"],0]out-2
in[["Connection: close","Server: nginx"],100]out-1
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
