dodoxandClaude Sonnet 5 3bbf524ebb Add simulator replica, persistence, planet scan, README; split empire state out of the repo
- tools/simulate.py + puga/simulate.py: replica of PRUNplanner's simulator (flows and
  efficiency verified against screenshots), reports real new capex (planned minus built)
- tools/scan.py: staffing variants, freight, HQ/experts, --planet mode, demolish-later,
  --min-n as a pure market-size filter, --json output
- tools/history.py, tools/persistence.py: margin history and short-horizon payback checks
- tools/plan_push.py: guarded delete; tools/state.py: syncs to empire/
- README with features and setup; CLAUDE.md made generic
- Own-empire material (profile, state, plans, notes) moved to gitignored empire/;
  generic examples in plans/examples and state/company.example.yaml

# Roadmap
Legend: [ ] todo, [x] done. Build order matters; each step is usable on its own.
1. [x] Repo skeleton, git (master), venv, CLAUDE.md, mechanics from PRUNplanner.
2. [x] `puga/fio.py`: cached FIO client (TTL per endpoint, keys from `.env`), plus `puga/prunplanner.py` for `api.prunplanner.org/data/*`. Inspect what `exchanges/` adds (VWAP?) vs FIO `/exchange/all`.
3. [x] (price + book tools done; cxpc trend history not needed, PRUNplanner has vwap7/30) `puga/market.py` + `tools/price.py`, `tools/book.py`: prices across all CX, trends from cxpc, order-book walk for real fill price at quantity N.
4. [x] `puga/econ.py` (22 tests pass, expected values from PRUNplanner's suite): efficiency stack, workforce consumption, hab LP, extraction (port the formulas from `docs/mechanics.md`, with tests against PRUNplanner values).
5. [x] (v1 done; see saturation-design.md for refinements) `tools/scan.py` (replaces prun_scan.py): depth-aware ROI. Per recipe report: buildings the market can absorb (output demand + traded volume, input supply), ROI at fill price for N buildings, absorbable profit/day. Filter `--min-buildings`. Both CX-local and universe.
5b. [ ] `tools/arb.py` (replaces prun_cxarb.py): inter-CX arbitrage on `market.walk` at real fill size; capital required, fuel/shipping cost from state, profit per trip within cash. Reason: old script uses top-of-book spread x min(supply,demand); on 2 of 4 top hits it overstated profit 7 to 11x (WAI, SCN).
6. [x] `tools/chain.py`: full bill of materials, make-vs-buy per node.
7. [ ] `tools/whatif.py`: marginal ROI of adding a building to the actual state (uses `state/company.yaml`, efficiency stack, imports).
8. [ ] `tools/planet.py`, `tools/found.py`: rank planets for a resource; founding cost including environment extras.
9. [ ] `tools/route.py`, `tools/haul.py`: jump graph, fuel, profit per trip.
9b. [x] (dry-run default, --apply after user yes) `tools/plan_push.py`: create/update `[PuGa]` plans in PRUNplanner from YAML (Api-Key auth; see decisions.md for guardrails).
10. [x] `tools/state.py sync` (sites, production efficiency, storage, ships, cash, permits): inventory, production, ships into `state/`.
11. [ ] Docs to fill: `docs/apex.md`, `docs/fio.md`, `docs/playbook.md` (question type -> tool), `docs/decisions.md`.
12. [ ] `tools/portfolio.py`: choose the set of 1-building opportunities for one base that maximises total profit given shared whole-building housing (HB1/HB2/...), capex, permits and (for demolish-later) 60-day value decay. Persistence check exists (`tools/persistence.py`); wire it into the ranking.
## Open questions
- PRUNplanner auth is known (`Authorization: Api-Key <key>`). FIO REST and FIO API are separate services with separate keys (separate services with separate keys; an earlier "one API" reading was wrong). Keys are in `.env`. Verified 2026-09-18: FIO_REST_KEY works on rest.fnar.net as `Authorization: <key>` (own /sites, /storage etc. readable); FIO_API_KEY gives 401 there, host unknown. PRUNplanner key works (plans 0, empires 1, cx prefs 1 on his account). Still unknown: the OpenAPI spec at https://doc.fnar.net/api.json has no securitySchemes. Probe with read-only calls.
- (resolved) PRUNplanner `exchanges/` has vwap_daily/7d/30d and traded volume; merged into `puga/market.py`. Trend history via cxpc still todo.
- Extraction: concentration to daily rate formula.
