+## PII scrubbing
+
+Same options as the web tracker's `pii` (#482). Scrubbing runs **when you call
+`track()`, before the event is queued**, so a raw value never reaches the
+on-device queue (NSUserDefaults / SharedPreferences) or the network.
+
+- **Denylist:** remove matching keys.
+- **Classify:** a per-key action. The first rule for a key wins.
+  - `DROP`: remove the key.
+  - `REDACT`: replace the value with `"<redacted>"`.
+  - `TOKENIZE`: replace it with `t:1`, `t:2`, …, stable for the tracker's lifetime.
+  - `HASH`: `h:` plus FNV-1a 32-bit hex. It's identical to the web tracker, so
+    the same value hashes the same on both platforms. **Not** cryptographic.
+
+Keys match exactly (case-sensitive) at any depth, including inside lists.
+
+```kotlin
+// Android
+val score = newScoreTracker(
+    context, config,
+    pii = PiiOptions.Classify(listOf(
+        PiiRule("email", PiiAction.HASH),         // joinable across web + app

+// queued and sent as {"email":"h:141e28bb","favouriteTeam":"home-club"}

+    publishableKey: "pk_…", siteId: "app.example.com-1a2b3c",
+    endpoint: "https://api.example.com",

+        PiiRule(field: "email", action: .hash_),     // `hash_`, not `hash`: that name is NSObject's
+        PiiRule(field: "phone", action: .redact),
+        PiiRule(field: "memberNumber", action: .tokenize),
+        PiiRule(field: "dateOfBirth", action: .drop),
+    ])
+)
+```
+
+To remove keys without per-field actions, use
+`PiiOptions.Denylist(listOf("email", "phone"))`.
 
 ## Auth0 (JWT)
 
-Mirrors the web tracker (#109): supply a token provider — it's consulted before
+Mirrors the web tracker's `getToken` (#109, #483): supply a token provider. It's
-each flush, so flushes carry a fresh access token. Failure → anonymous, never
+consulted before each flush, so flushes carry a fresh access token. It is
-halts.
+**async**, so hand it Auth0's own refresh call directly; there's nothing to block
+on or cache yourself.
 
 ```swift
-score.setTokenProvider { Auth0Session.shared.accessToken } // called before each flush
+// iOS — Auth0.swift's CredentialsManager renews the token when it's expired.
+score.setTokenProvider { try await credentialsManager.credentials().accessToken }
 score.identify(userId: "auth0|abc123")   // optional: set userId now
 ```
 ```kotlin
-score.setTokenProvider { auth0.credentials?.accessToken }
+// Android — Auth0.Android's CredentialsManager has a suspend awaitCredentials().
+score.setTokenProvider { credentialsManager.awaitCredentials().accessToken }
 score.identify("auth0|abc123")
 ```
 
+### Signing in: traits and replay (#488)
+
+`identify` takes the fan's traits, sent on an `identify` event (consent-gated
+and PII-scrubbed like any props). Pass `replayAnonymousEvents` to re-send the
+events the app already sent while the fan was signed out, now with the fan
+attached, so a poll vote cast before sign-in still earns its karma:
+
+```swift
+score.identify(userId: "auth0|abc123", traits: ["team": "urc-leinster"], replayAnonymousEvents: true)
+```
+```kotlin
+score.identify("auth0|abc123", traits = mapOf("team" to "urc-leinster"), replayAnonymousEvents = true)
+```
+
+Replay is opt-in. It re-sends at most the last 100 anonymously sent events
+(`identifyReplayBufferSize` on the factory / `ScoreClient` init), only those
+current consent still allows, marked `_backfill: true` with `_originalEventId`.
+Events still waiting in the queue aren't replayed: they go out with the fan on
+the next flush. The buffer lives in memory only, so it's empty after a cold
+start.
+
+How the provider is used:
+- **Before each flush**, and **single-flight**: overlapping flushes share one
+  in-flight call instead of starting several.
+- **Bounded:** if it hasn't answered within 5 s, the flush goes ahead without
+  waiting. The call keeps running, and its token is used once it arrives.
+  Android can change this with the `tokenRefreshTimeoutMs` parameter on
+  `ScoreTracker`.
+- **Never halts tracking:** if the provider throws or returns null, the flush
+  uses the last known token, or goes anonymous if there isn't one.
+- A synchronous closure still works (`{ cachedToken }`), so existing code
+  compiles unchanged.
+
 ## Offline & flushing
 
 - **Durable queue:** events persist (NSUserDefaults / SharedPreferences), survive
   cold start, are FIFO-capped (oldest dropped), and clear only on a successful
   POST (a failed flush retains them for retry).
-- **Auto-flush:** `score.startAutoFlush(everySeconds: 30)` (iOS) /
+- **Lifecycle & connectivity — one call (#484).** Bind the tracker once at
-  `score.startAutoFlush(scope, intervalMs)` (Android).
+  startup and it flushes when it should:
-- **Lifecycle hooks:** call `onForeground()` / `onNetworkAvailable()` to flush
+
-  promptly — wire them to `UIApplication`/`NWPathMonitor` (iOS) or
+  ```swift
-  `ProcessLifecycleOwner`/connectivity callbacks (Android).
+  // iOS — in application(_:didFinishLaunchingWithOptions:)
+  score.bindToAppLifecycle()
+  ```
+  ```kotlin
+  // Android — in Application.onCreate(), on the main thread
+  score.bindToAppLifecycle(this)
+  ```
+
+  | When | What the tracker does |
+  |---|---|
+  | App comes to the foreground (or is already there when you bind) | Flush, and flush every 30 s while it stays there |
+  | App goes to the background | Stop the periodic flush; one **best-effort flush bounded to 5 s**, so it can't hold up suspension (on iOS, inside a background task that ends as soon as the flush does) |
+  | Network comes back | Flush |
+
+  Both platforms run the same shared logic. Options: `autoFlushEverySeconds` /
+  `autoFlushIntervalMs` (`nil`/`null` to run your own auto-flush) and
+  `backgroundBudgetSeconds` / `backgroundBudgetMs`. Undo with
+  `unbindAppLifecycle()` (iOS) or `close()` on the returned binding (Android).
+  Android declares `ACCESS_NETWORK_STATE` in the library manifest, a normal
+  permission with no prompt. A bounded flush that runs out of time loses
+  nothing: events leave the queue only after their POST succeeds.
+- **Delivery tiers (#487).** Mark an event that must not be lost as critical:
+
+  ```swift
+  score.track(Events.shared.PollVote, props: […], delivery: .critical)        // iOS
+  ```
+  ```kotlin
+  score.track(Events.PollVote, mapOf(…), delivery = DeliveryMode.CRITICAL)    // Android
+  ```
+
+  Critical events go out first in every flush, survive app restarts as
+  critical, and are the last to go when the queue is full: best-effort
+  events, including new ones, are shed before any critical event. If a
+  critical event is lost anyway, because it aged past 72 h or the queue was
+  entirely critical, the SDK sends a `delivery_failed` event naming it
+  (`originalEventId`, `originalEventName`, `reason`: `age_evicted` or
+  `queue_full`), the same event the web tracker sends. The tier is local:
+  it never appears on the wire.
+- **Manual control instead:** binding is opt-in. Skip it and call
+  `onForeground()`, `onBackground()` and `onNetworkAvailable()` yourself, plus
+  `startAutoFlush(everySeconds: 30)` (iOS) / `startAutoFlush(scope, intervalMs)`
+  (Android).
