@@ -11,9 +11,21 @@ Format based on [Keep a Changelog](https://keepachangelog.com/).
 - Star map gate topology — 300-node network with 334 edges across 6 sectors, generated and hand-tuned for natural corridor structure in frontier space
 - Star map generation pipeline — seed-based generator, sculpting script, core sector patcher, topology tuner with bridge-safe connectivity guarantees
 - d2 sector diagrams — 6 sector maps + overview visualization of gate network
+- Multi-table star systems DB schema with GJ catalog IDs as primary keys — 8 tables covering identity, gates, history, economy, factions, culture
+- Full wiki prose for 10 core systems — Sirius, Ran, Tau Ceti, Sol, Arbour, Groombridge, Struve, Cygni B, ACB, Bastion
+- Corporation wiki pages — Gate Corporation, Mastroianni Vehicle Group, Prometheus Labs
+- Wiki category index pages for star-systems, corporations, factions, technology, contraband, concepts
+- 10 next-tier systems named and assigned roles — Renaissance, Nova Roma, Prometheus, Proxima, Rigil Kentaurus, Barnard's Star, Lacaille, Cairn, Meridian, Aurelius
+- `hop_distance_from_gateway` column in system_gates table
 
 ### Changed
 - D-095 aperture range amended from 4-8 to 1-8 — single-aperture dead-end systems valid for isolated frontier outposts
+- D-095 amended: inter-system gates are alien-built (aperture count alien-determined), intra-system span gates are human-built (Institute reverse-engineering, Gate Corporation license)
+- All system identifiers migrated from arbitrary S-numbers to GJ astronomical catalog IDs
+- Q-039 (gate topology generation) resolved by 301-system star map
+
+### Removed
+- Redundant `astronomical_id` column from star systems schema (system_id IS the GJ number)
