 ## [Unreleased]
 
 ### Added
+- Economics schema extension (#804): 5 new tables in systems.db (gate_links, commodities, production_chains, chain_inputs, corp_presence) + currency_zone and corporation archetype columns
+- Economics import pipeline (`tooling/economy-db/import_economics.py`): reads TOML/JSON source data, populates systems.db. Idempotent via `make economy-db`
 - Planet generator pipeline (`tooling/planet-gen/`) — procedural terrain simulation, Whittaker biome classification, equirectangular heightmap + 512px globe rendering from wiki data
 - Externalized biome/color configuration (`tooling/planet-gen/biomes.toml`) — single source for all classification tables, palettes, and rendering parameters
 - Batch runner with error handling, resume support, determinism verification, and 50% error rate circuit breaker

 - Sprint worktree creation no longer spawns a spurious "None" team tab when tickets have no team assigned
 
 ### Changed
+- Renamed `commission_certified` → `commission_certifiable` across all TOML, schema, and decision files — flag is a susceptibility marker, not an absolute state
 - Pre-push hook now validates JSON syntax on changed files (python3 -m json.tool)
 - HUD status panel: merged TimeDisplay into ImplantPanel — time, health, perception in one themed panel (#786)
 - HUD moved from UILayer (20) to InsertOverlay (10) for bloom treatment per D-049
