**Still reproduces as of 2026-06-30** (independent of LakeSail — different
tenant, North Europe region), so adding a data point to the "is it fixed on the
OneLake side?" question.
`deltalake` 1.6.0 (object_store Azure) reads still fail with `Generic delta
kernel error: No files in log segment`. I captured the actual wire traffic via
a TLS-intercepting proxy. The kernel's log listing is:
```
GET /<workspace>?restype=container&comp=list
&prefix=<lakehouse>/Tables/<schema>/<table>/_delta_log/
&startFrom=<lakehouse>/Tables/<schema>/<table>/_delta_log/00000000000000000000
```
Replaying that exact `List Blobs` by hand, varying only `startFrom`, against
an unmodified token:
| `startFrom` | blobs returned |
|---|---|
| *(omitted)* | `…/_delta_log/00000000000000000000.json`, `…0001.json` |
| `…/_delta_log/00000000000000000000` (what object_store sends) | **none** |
| `…/_delta_log/` (the prefix itself) | **none** |
Any non-empty `startFrom` yields an empty result — including values that
sort *before* the target files (`…00000000000000000000` <
`…00000000000000000000.json`), which a compliant response must still return.
The empty response is **HTTP 200 with `<Blobs />` and an empty `<NextMarker
/>`** — i.e. a final page, not a pagination continuation, so this is
server-side and not object_store under-fetching.
Reproduces identically on two different table types:
- a Lakehouse schema-shortcut table (GUID-form abfss URL), and
- a Warehouse table (friendly-name abfss URL).
So whatever was deployed, `startFrom` on this region/tenant still returns
empty for `_delta_log` listings. Happy to provide more captures if useful.
