Adds native Command Center features (no new containers) integrated as sub-tabs
in the existing Data Explorer and Data Quality views:
- Continuous Data Quality (dq_monitor.py): live completeness/uniqueness/validity/
freshness scorecards via Trino with rolling trends → DataQuality "Live Monitoring".
- Ownership & stewardship (catalog_governance.py): owner/steward/tier matrix,
orphan detection, business glossary; local store best-effort synced to
OpenMetadata (owner PATCH) → Data Explorer "Ownership".
- Access & policy posture: per-dataset compliance combining PII masking, ownership,
live DQ and observability alerts vs data contracts → Data Explorer "Access & Policies".
- Lineage (lineage.py): staged source→CDC→Spark→S3→Iceberg→Trino→serving graph with
live row counts and column-level PII/masking tracing → Data Explorer "Lineage".
- Observability (observability.py): volume/freshness/schema-drift monitoring with
alerts → Data Explorer "Observability".
- Shared lake_meta.py dataset registry + bounded Trino client; fast native row-count
and PK-indexed freshness so monitors stay cheap on 25-54M-row tables.
- LLM context (lab_context.py) enriched with DQ scores, ownership and active alerts.
Agent terminals were idle (one-shot probe) while agents were busy in the
background. Now every agent streams what it is actually doing:
- agent_terminal: emit_threadsafe() so background threads can stream lines.
- agent_ops: Data Custodian DML loop logs the real INSERT/UPDATE/DELETE SQL
(+ Mongo ops) and Hadoop-offload Trino CTAS/INSERT to its terminal; ETL
Guardian announces each orchestrated movement.
- movements: trigger_and_watch streams the Airflow DAG / API call, conf,
before/after Trino counts and result to the owning agent terminal.
- etl_offload: per-dataset read + pyarrow->S3 parquet writes and cycle
summaries stream to the ETL Guardian terminal.
- agent_activity (new): round-robin live probes for Lakehouse Ops, Hadoop
Ranger (NameNode JMX + YARN), Infra Sentinel (Dockhand inventory + host
load) and Network Watcher (VLAN 20/21 path checks).
- fix: YARN ResourceManager runs on 10.0.21.62:8088 (was .61).
- ui: terminal dock merges the selected agent ops stream with the node probe.
lab_context now includes an in-process governance section so the LLM knows the
live CDC volume, data movements + last-run state, the PII catalog (OM+heuristic)
with masked/unmasked status, and source->masked lineage.
