+# Sprint 29: Body Catalog — Copy Team Briefing
+
+**Sprint goal:** Complete body catalogs for all 258 remaining systems across all corridors.
+**Agents:** Miri (naming), Paula (narrative review), Ozzie (astrophysical + experience review)
+**Scope:** 258 systems, hops 4-12, all 5 corridors
+
+## Pipeline
+
+Each system follows the `/atlas author-system` pipeline:
+
+1. Read wiki (index.md + gttr.md) — build context
+2. Generate astrophysical skeleton — `tooling/atlas author "{system_id}"`
+3. Spawn Miri for naming — wiki-derived register, collision avoidance
+4. Paula narrative review — names, population, stations vs wiki coherence
+5. Paula + Ozzie dual review — narrative integrity + astrophysical sanity
+6. Integrity check — automated verification
+7. Commit — one system per git commit
+
+See `.claude/skills/atlas/references/author-system.md` for full details.
+
+## Work Order
+
+Process by corridor, hop-order within each corridor (closest to Gateway first).
+5 parallel tracks can run simultaneously on separate worktree branches.
+
+| Track | Story | Corridor | Systems | Hop Range |
+|-------|-------|----------|---------|-----------|
+| A | #739 | North Reach | 43 | 4-12 |
+| B | #740 | South Reach | 47 | 4-10 |
+| C | #741 | East Reach | 47 | 4-10 |
+| D | #742 | West Reach | 48 | 4-11 |
+| E | #743 | Deep Frontier | 73 | 5-12 |
+
+Use `tooling/atlas next {hop}` to get the system list per hop.
+Use `tooling/atlas unfinished` to see all remaining systems.
+
+## PR Strategy
+
+One PR per corridor track. Each track runs on its own worktree branch.
+~50 systems per PR is reviewable; 258 in one PR is not.
+
+| Branch | PR scope |
+|--------|----------|
+| copy-north | Track A: 43 north_reach systems |
+| copy-south | Track B: 47 south_reach systems |
+| copy-east | Track C: 47 east_reach systems |
+| copy-west | Track D: 48 west_reach systems |
+| copy-frontier | Track E: 73 deep_frontier systems |
+
+Merge order: any order, but run name collision check before each merge.
+
+## Quality Standards (from hops 0-3)
+
+- **Body count:** G/F stars 8+, K stars 7+, M dwarfs 6+, A/B stars 6+
+- **Always include:** oort cloud, asteroid belt, gas giant (most systems), horizon station
+- **Names:** Inhabited bodies + all stations get proper_name. Uninhabited bodies = null. Wiki names override Miri.
+- **Population:** Hub 1-5B, junction 500M-2B, loop/through 200M-1B, dead end 10M-500M. Adjust for wave + role.
+- **No translations in notes** — translations flatten names into labels
+- **One commit per system** — never batch
+
+## Tickets
