paulandClaude Opus 4.8 902758ce67 Build stock-deep-evaluation v1: single-stock equity evaluation app
Next.js 15 + TypeScript app implementing the fully-specced first change.
Pipeline: resolve -> market data -> pure evaluation engine -> budget guard
-> analysis agent -> report.

- market-data: DataProvider interface, offline FixtureProvider (DE/SPY seeded
  from the reference example), FmpProvider (FMP free tier), TTL cache + retry.
- technicals: pure MA/volatility/swing/52-week math.
- evaluation: instrument-aware pure engine; equity branch built, ETF gated to
  "not yet supported". Reproduces the DE example (P/E 34.5, fwd 29.3, $167.6B).
- agent: AnalysisAgent interface; default Claude Code CLI transport (headless,
  subscription-backed, web-grounded), Anthropic API alternate via config.
- cost-controls: price table, spend store, monthly budget guard.
- UI: ticker search + deep-dive toggle, report view, price chart with marked
  entry/exit/stop levels, cost/budget display, ETF/not-found states.

31 vitest tests, typecheck, production build, and lint all pass. Verified
end-to-end via the API for DE, SPY, and an unknown ticker. Live Claude CLI
agent test is the documented pick-up point (see README).
