Full rewrite of Flights/Services/JSXWebViewFetcher.swift implementing a
19-step WKWebView flow that drives the jsx.com one-way search UI, then
calls POST /api/nsk/v4/availability/search/simple directly via fetch()
from within the page context using the anonymous auth token read from
sessionStorage["navitaire.digital.token"].
Why the direct call instead of clicking Find Flights: WKWebView's
synthetic MouseEvents have isTrusted=false, and JSX's custom datepicker
commits its day-cell selection into the Angular FormControl only on
trusted user gestures. The result is that the date input displays
"Sat, Apr 11" but the underlying FormControl stays null, so Angular's
search() sees form.invalid === true and silently returns without
firing a request. Playwright sidesteps this because CDP's
Input.dispatchMouseEvent produces trusted events; WKWebView has no
equivalent. The fix is to drive the UI steps (for page warm-up and
smoke testing) but then call the API directly — the same-origin fetch
inherits the browser's cookies and TLS fingerprint so Akamai sees it
as legitimate traffic, same as the lowfare/estimate GET that already
works through the page.
Every step has an action and one or more post-condition verifications.
On failure the runner dumps the action's returned data fields, page
state (URL, selector counts, form error markers), and both the last
initiated AND last completed api.jsx.com calls so network-level blocks
and form-validation bails can be distinguished.
New return type JSXSearchResult exposes every unique flight from the
search/simple response as [JSXFlight] with per-class load breakdowns
(classOfService, productClass, availableCount, fareTotal, revenueTotal)
so callers can see all flights, not just one.
Flights/Services/AirlineLoadService.swift: fetchJSXLoad now consumes
the [JSXFlight] array, logs every returned flight, and picks the
requested flight by digit-match. Deleted 495 lines of dead JSX helpers
(_fetchJSXLoad_oldMultiStep, parseJSXResponse, findJSXJourneys,
extractJSXFlightNumber, extractJSXAvailableSeats,
collectJSXAvailableCounts, parseJSXLowFareEstimate, normalizeFlightNumber).
scripts/jsx_playwright_search.mjs: standalone Playwright reference
implementation of the same flow. Launches real Chrome with --remote-
debugging-port and attaches via chromium.connectOverCDP() — this
bypasses Akamai's fingerprint check on Playwright's own launch and
produced the UI-flow steps and per-flight extractor logic that the
Swift rewrite mirrors.
