v0.9.2

register_hex_tiles no longer advertises GeoJSON output (#434, #219)

The GeoJSON output path was removed in #241, but the tool description still told models the server picks "a single GeoJSON file for small/bounded results". It now says the server always builds a vector tile pyramid. There is no behaviour change. The matching client-side fix to add_hex_tile_layer is in geo-agent v3.36.0 (SchmidtDSE/glen#404).

v0.9.1

Bounded, per-connection DuckDB spill (#423, #426)

• Spill cap: each DuckDB connection's max_temp_directory_size is set to 50% of the container's ephemeral-storage limit (POD_EPHEMERAL_LIMIT, via the Downward API; override with DUCKDB_MAX_TEMP_DIRECTORY_SIZE). An oversized spill now fails its own query with a DuckDB error, instead of the kubelet evicting the pod.
• Private spill directories: each query and tile connection spills into its own /tmp/duckdb-<uuid> (root set by DUCKDB_TEMP_ROOT). Concurrent spills into a shared /tmp used to overwrite each other's files and segfault the server.

Deployments must add the POD_EPHEMERAL_LIMIT env (resourceFieldRef: limits.ephemeral-storage) to get the cap. Without it, only the private directories apply.
