- decide_approval now executes the underlying data movement when an approved
request carries an executor=movement payload (real human-gated executor).
- rag-api service gets OPENMETADATA_* (via atc.env) + COMMAND_CENTER_URL so it can
sync the catalog and call platform tools.
- Knowledge Chat gains an Agent-mode toggle (SSE tool-loop with step chips) and a
'Sync catalog' button.
Add OpenMetadata node (atc-docker02 .47) to node_registry with UI links.
pii_catalog now reads OM column PII tags (Presidio auto-classification) as the
authoritative source, merged with the name heuristic; OPENMETADATA_URL wired
into the api service (token via atc.env).
Deploys Apache Hive 3.1.3 (Derby metastore + external table over the HDFS
historical CSV, MapReduce exec) on the Hadoop master, so the engine comparison
shows a REAL measured Hive latency (~5.2s) next to live Trino (~0.3s); Impala
stays clearly-labelled representative. The API re-measures Hive over SSH on a
30-min TTL (cached + persisted, with a committed seed). Adds filters
(year/region/category/channel), a region×category heatmap, Trino exec stats,
and a "where is this data read from" lineage panel (Trino->S3/Iceberg/Parquet
with snapshot+files, Hive->HDFS/CSV with namenode+files). Mounts host SSH key
read-only into the api container for the live Hive benchmark.
