@@ -36,6 +36,11 @@ APIs change between minors without a deprecation period.
   `ctl model plan` and `ctl model serve` take those repositories too, and the explorer names a `strata-ple`
   repository for what it is: part of a pack Strata knows, or one Strata 0.2.7 does not.
 
+### Fixed

+- **A repository that keeps each quantisation in a directory of its own** (ISTA-DASLab's `IQ2_XS/`, `IQ3_S/`) listed
+  no weights: its file tree is now read recursively, by the explorer, the plan and `ctl model serve`.

 ## v0.16.0 — 2026-10-30
 
 Weights pinned to the commit they were added at and checked, by the nodes and the mirror, against the sha256
