feat(demo): snapshot AAPL market data, serve in demo mode#242
Merged
Conversation
The Market tab in demo mode previously returned `{ results: null, error:
"Demo mode — market data is not available." }` for every endpoint —
visitors got an empty page. This wires up real AAPL data captured from
Alice's own market-data layer, frozen as JSON fixtures.
## Capture method
1. `pnpm dev` → Alice on :47331 (FMP provider via in-process
opentypebb, already configured with a working API key)
2. curl 9 endpoints with `?symbol=AAPL`:
- /api/market/search?query=AAPL
- /api/market-data-v1/equity/profile
- /api/market-data-v1/equity/price/quote
- /api/market-data-v1/equity/price/historical?interval=1d&start_date=…&end_date=…
- /api/market-data-v1/equity/fundamental/{metrics,ratios,balance,income,cash}
3. Save raw JSON responses verbatim to ui/src/demo/fixtures/market/.
Through-backend capture (rather than direct FMP) guarantees the
response shape matches whatever the UI expects, including any
opentypebb-layer normalization.
## Behavior
Handler returns the snapshot when `symbol === 'AAPL'`; for any other
symbol it returns `demoMarketEmpty` — a `{results:null, provider:
'demo', error:"Demo mode — only AAPL data is snapshotted. Install
OpenAlice locally to query other symbols."}` payload that the
UI's existing empty-state branch renders cleanly. No silent
"wrong-symbol-shows-Apple-data" failure mode.
Search matches `AAPL` / `apple` / any prefix of `apple inc.`.
## Verified
- pnpm -F open-alice-ui exec tsc -b: clean
- pnpm -F open-alice-ui build (prod): main chunk has zero `Apple Inc`
/ `aapl-equity` / `demoMarketAAPL` / `312.06` matches (single `MA50`
match traces to real UI's QuoteHeader.tsx column label, unrelated)
- pnpm dev:demo + Playwright walk:
- /market: search box prompts
- type "AAPL": dropdown shows "AAPL — Apple Inc. [EQUITY]"
- click: routes to /market/equity/AAPL, renders price 312.06 with
-0.45 (-0.14%) change, full quote panel (open/prev/high/low/
volume/mkt-cap/52w-high/52w-low/MA50/MA200), 62-bar daily candle
chart 2026-03-03→05-29, Profile + Key Metrics panels populated
Snapshot date: 2026-05-29 (provider=FMP). Resnap if a UI contract
change forces it — same capture method works.

Summary
The Market tab was empty in demo mode — every endpoint returned `{ results: null, error: "Demo mode — market data is not available." }`. This PR captures real AAPL data from Alice's own market-data layer and freezes it as JSON fixtures, so visitors can search AAPL and see a real-looking equity detail page.
Snapshot method
Going through-backend (vs hitting FMP directly) guarantees the response shape matches what the UI expects — no manual translation layer, no opentypebb-layer normalization to recreate.
Handler behavior
Verified
Boundary touch
None — demo fixtures + handler only. The Alice backend was used to generate the fixtures but no production code modified.
Snapshot freshness
Date: 2026-05-29 (provider=FMP). When/if a UI contract change forces a re-snap, the same capture method works — boot Alice, curl with `?symbol=AAPL`, replace JSON files.
