# StaffTraveler Firestore schema (live-extracted)

Captured 2026-04-22 via Playwright MCP on `https://app.stafftraveler.com` while logged in as `stafftraveler@treymail.com` (uid `3NNPesQMiMRNYnPmuQzh6w2YKyh1`, airline `st_SWA`). All queries/docs below are copied from the web client's `firestore.googleapis.com/.../Listen/channel` `addTarget` bodies — not guessed.

## Why iOS mitm didn't show this

The iOS Firebase SDK and Android SDK both use the gRPC transport to `firestore.googleapis.com` (HTTP/2 with protobuf frames). Many mitm setups decode HTTPS but not gRPC framing, so the requests appear as opaque binary. **The web client uses the `VER=8 TYPE=xmlhttp` long-poll fallback — plain HTTP POST with URL-encoded JSON bodies** — which is fully readable. That's why we only saw this via the browser.

## Required headers for REST access

Direct REST (`/v1/projects/.../documents:runQuery` or `/documents/...`) works with:

```
Authorization: Bearer <firebase id token>
X-Firebase-GMPID: 1:628258099825:web:35b20eaab4d441894041d0
X-Goog-Api-Client: gl-js/ fire/12.12.0
?key=AIzaSyD82Hiqx-jAbHF8faMGSveqLw8CdX8a-Uc      (URL query param)
```

Note: **web API key** (`AIzaSyD82...`), not the Android key from strings.xml. Omitting `?key=...` or the GMPID header causes `403 PERMISSION_DENIED` — the rules consult the key for the project consumer context before evaluating `allow read`.

## Single-document subscriptions

These are fetched as `addTarget.documents.documents`:

| Path | What |
|------|------|
| `__system/maintenance` | Server maintenance flags |
| `__system/version` | Required client versions (public) |
| `users/{uid}` | Profile: airlineStCode, airlineId, firstName, gender, … |
| `userHints/{uid}` | UI hints the user has dismissed |
| `userRequestCounters/{uid}` | Regular-request quota state |
| `userPriorityRequestCounters/{uid}` | Priority-request quota state |
| `userCredits/{uid}` | Credit balance |
| `userAchievements/{uid}` | Unlocked achievements |
| `userMetrics/{uid}` | Usage telemetry |
| `userFlightSearchHistory/{uid}` | Recent searches |
| `airportsByIata/{IATA}` | Public airport lookup (DFW, LAS, …) |
| `airlinesBySt/{stCode}` | Airline lookup by StaffTraveler code (`st_AAL`, `st_SWA`, …) |
| `airlineNotesBySt/{stCode}` | Non-rev agreement notes per airline |
| `flightEquipment/{iataOrId}` | Aircraft type info (`32Q`, `321`, `738`, …) |
| `conversations/{flightId_v3}` | Flight-level comment thread |
| `derivedLoadsReports/{reportId}` | **Individual load report doc — see below** |
| `trackedFlights/{flightId_v3}` | User's tracked flight state |

## Collection queries

### `derivedLoadsReports` — THE LOADS DATA

```json
{
  "from": [{"collectionId": "derivedLoadsReports"}],
  "where": {
    "fieldFilter": {
      "field": {"fieldPath": "flightId"},
      "op": "EQUAL",
      "value": {"stringValue": "AA_2178_DFW_2026_04_22"}
    }
  },
  "orderBy": [
    {"field": {"fieldPath": "createdAt"}, "direction": "DESCENDING"},
    {"field": {"fieldPath": "__name__"}, "direction": "DESCENDING"}
  ]
}
```

**This is the query you want for the Flights integration.** Pass the flight `id_v3` (e.g. `AA_2178_DFW_2026_04_22` — format is `{airlineId}_{flightNumber}_{departureIata}_{YYYY}_{MM}_{DD}`).

**Access control (verified 2026-04-22):** this query returns `403 PERMISSION_DENIED` unless the user has an active `trackedFlights/{flightId_v3}` doc, which is created only by `POST /v1/commands/user/createLoadsRequests`. That call spends a credit on flights the user has never requested; replay on an already-requested flight is idempotent (no charge). So:

- Freely re-read `derivedLoadsReports` for any flight you've already requested — no cost, no rate limit observed.
- You cannot peek at loads without first requesting — the "instant results" in the app for flights with recent community reports rely on the user having previously paid the credit.
- On the 15 DFW-LAS flights tested, only `AA_2178_DFW_2026_04_22` (the one with an open request) returned 200; the other 14 all returned 403. Same for 29 LAX-JFK flights the user hadn't requested — all 403.

Example doc (captured AA2178 2026-04-22 12:42 PM CT):
```json
{
  "flightId": "AA_2178_DFW_2026_04_22",
  "openSeats": {
    "first":   {"count": 3},
    "eco":     {"count": 9}
  },
  "staffListing": {
    "type": "available",
    "count": 6,
    "countByClass": {}
  },
  "responseTimeSeconds": 196,
  "numberOfCreditsRewarded": 1,
  "isFlagged": false,
  "isFlaggedConfirmed": false,
  "seatsAvailabilityScore": 0.79,
  "hasClosedRequest": true,
  "isJackpotHit": false,
  "isPriorityRequest": false,
  "createdAt": "2026-04-22T18:42:51.313Z",
  "expireAt":  "2026-07-21T21:45:00Z",
  "creatorName":      "M",
  "creatorImageUrl":  "https://images.stafftraveler.com/avatars/happysuitcase.png",
  "creatorImagePath": "avatars/happysuitcase.png"
}
```

Field notes:
- `openSeats.<class>.count` — **exactly what the app shows as "OPEN SEATS"**. Classes seen: `first`, `business`, `premiumEconomy`, `eco`. Absent class = 0 or unknown.
- `staffListing.count` — **the "LISTED NON-REV PASSENGERS" number**.
- `staffListing.type` — `"available"` means loads were given; other types likely include `"upgrade"` variants (see `checkForLoads` heuristic in `bundle.hasm`).
- `seatsAvailabilityScore` — 0-1, app uses this to color-code the flight.
- `creatorName` is the first letter only (privacy).
- `expireAt` — ~90 days out, so load reports stay queryable.

### `trackedFlights` — your open requests

```json
{
  "from": [{"collectionId": "trackedFlights"}],
  "where": {
    "compositeFilter": {"op": "AND", "filters": [
      {"fieldFilter": {"field": {"fieldPath": "status"}, "op": "EQUAL", "value": {"stringValue": "open"}}},
      {"fieldFilter": {"field": {"fieldPath": "hasDeparted"}, "op": "EQUAL", "value": {"booleanValue": false}}},
      {"fieldFilter": {"field": {"fieldPath": "scheduledFlight.airlineStCode"}, "op": "EQUAL", "value": {"stringValue": "st_SWA"}}}
    ]}
  },
  "orderBy": [
    {"field": {"fieldPath": "priority"}, "direction": "DESCENDING"},
    {"field": {"fieldPath": "scheduledFlight.departureTimeUtc"}, "direction": "ASCENDING"},
    {"field": {"fieldPath": "__name__"}, "direction": "ASCENDING"}
  ],
  "limit": 25
}
```

Returns the logged-in user's open requests filtered by their airline. Doc ID = flight id_v3. `scheduledFlight` is the embedded full flight object (matches `searchFlightsByRoute` item shape).

### `trackedFlights/{flightId}/statusUpdates`

```json
{
  "from": [{"collectionId": "statusUpdates"}],
  "orderBy": [
    {"field": {"fieldPath": "createdAt"}, "direction": "DESCENDING"},
    {"field": {"fieldPath": "__name__"}, "direction": "DESCENDING"}
  ],
  "parent": "projects/stafftraveler-prod/databases/(default)/documents/trackedFlights/AA_2178_DFW_2026_04_22"
}
```

Delay / gate / equipment changes for that flight over time.

### `users/{uid}/pinnedFlights`, `users/{uid}/connectingFlights`

Subcollections under the user doc. Empty for this account.

### `autoRequestRecords` where `subscribedUserIds ARRAY_CONTAINS {uid}` AND `isActive`

Auto-request subscriptions — flights the user has set up to auto-request loads for on a recurring schedule.

### `trackedFlights` where `subscribedUsers.{uid} == true` AND `isDeleted == false`

Other users' requests that THIS user has subscribed to (so they also see the loads when answered).

## Idempotent REST access pattern (integration recipe)

```bash
# 1. sign in (you already do this)
TOKEN=$(curl -sX POST "https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=$WEB_KEY" \
  -d "{\"email\":\"$EMAIL\",\"password\":\"$PW\",\"returnSecureToken\":true}" | jq -r .idToken)

# 2. read loads for any flight
BASE='https://firestore.googleapis.com/v1/projects/stafftraveler-prod/databases/(default)/documents'
KEY='AIzaSyD82Hiqx-jAbHF8faMGSveqLw8CdX8a-Uc'
curl -sX POST "$BASE:runQuery?key=$KEY" \
  -H "Authorization: Bearer $TOKEN" \
  -H "X-Firebase-GMPID: 1:628258099825:web:35b20eaab4d441894041d0" \
  -H "Content-Type: application/json" \
  -d '{"structuredQuery":{"from":[{"collectionId":"derivedLoadsReports"}],"where":{"fieldFilter":{"field":{"fieldPath":"flightId"},"op":"EQUAL","value":{"stringValue":"AA_2178_DFW_2026_04_22"}}},"orderBy":[{"field":{"fieldPath":"createdAt"},"direction":"DESCENDING"}]}}'
```

Returns empty array if no report exists yet (meaning you'd need `createLoadsRequests` first to ask the crew). If a report exists, you get it without spending a credit.

## Integration plan for the iOS Flights app (final)

1. Secondary `FirebaseApp` configured against `stafftraveler-prod` with the web API key + GMPID above.
2. `Auth.auth(app: stApp).signIn(withEmail:password:)` with user's StaffTraveler credentials, refresh token stored in Keychain.
3. Use `Firestore.firestore(app: stApp)` and wire:
   - `collection("derivedLoadsReports").whereField("flightId", isEqualTo: flightIdV3).addSnapshotListener { ... }` — live load updates per flight
   - `collection("trackedFlights").whereField("status", isEqualTo: "open")....whereField("scheduledFlight.airlineStCode", isEqualTo: userStCode).limit(to: 25).addSnapshotListener` — user's open requests list
   - `document("airlinesBySt/\(stCode)")` — airline metadata
   - `document("airportsByIata/\(iata)")` — airport metadata
4. For writes (request loads, submit report, etc.), keep using the HTTP commands API at `https://api.stafftraveler.com/v1/commands/user/<cmd>`.

No App Check enforcement observed from the web client — plain Firebase ID token + API key is sufficient.
