fix: harden portal OTA release

Use the DFTE async integration helper so portal HTML chunk callbacks handle
zero-length buffers and no-progress retries without terminating transfers
early on constrained hosts.

+# Changelog
+
+## 3.2.5
+
+- Prevent ESP8266 portal firmware uploads from yielding in ESPAsyncWebServer's
+  SYS callback. The updater now enters asynchronous mode before its first
+  erase or write, so the real browser upload can complete and restart into
+  the new firmware image.
+- Send the successful portal OTA response before scheduling the restart, so
+  browsers can observe a completed HTTP exchange on both ESP8266 and ESP32.
+- Give ESP32's Wi-Fi radio a five-second hand-off interval before a user scan
+  retry, avoiding transient scan failures immediately after completion.
+
+## 3.2.4
+
+- Correct profile-backed Wi-Fi hand-off from the embedded web portal: the
+  station controller now owns attempts started through either portal surface,
+  preventing the legacy empty-SSID path from reporting success before a
+  station address is available.
+
+## 3.2.3
+
+- Clarify the public integration boundary, built-in browser protocol, and
+  portal presentation documentation without coupling the standalone library to
+  DeviceFramework.
+- Refresh the standalone test guidance and pin the packaged DFTE dependency to
+  the validated 1.2.1 release.
+
+## 3.2.2
+
+- Align the direct ESP8266 and ESP32 test environments with the packaged DFTE 1.2.0 dependency.
+
+## 3.2.1
+
+- Ensure externally supplied station profiles remain authoritative on ESP32 by clearing stale SDK-owned credentials before opening the portal for an empty or invalid external profile set.
+- Pin DFTE 1.2.0, the tested template-engine release used by the maintained portal.
+
+## 3.2.0
+
+- Refine the device-hosted portal with a startup Wi-Fi scan, stable loading overlays, clearer connection progress, and a resettable configuration timeout.
+- Keep a successful portal-to-station hand-off reachable until the browser acknowledges its redirect, with a bounded fallback for captive or headless clients.
+- Rename the presentation field `homeIntro` to `tagline` so portal identity and wording are clearer; update portal bootstrap contract to v3.
+- Add focused Basic Portal, Branded Portal, Custom Portal Content, and Station Profiles examples for ESP8266 and ESP32, with real-hardware README captures.
+- Strengthen release CI with documentation and clean-consumer/example compilation checks for both supported targets.
+
+## 3.1.0
+
+- Add an opt-in primary/fallback station-profile controller with bounded failover, reconnection, a durable consumer-supplied store, and profile-aware portal APIs. DeviceFramework uses this to persist verified WiFi profiles transactionally.
+- Add portable portal branding and presentation hooks, including theme-aware shell and template rendering, without requiring DeviceFramework.
+- Pin ESP32 tests to the Arduino 3-compatible pioarduino platform release and resolve DFTE 1.1.0.
+
+## 3.0.6
+
+- Correct async PlatformIO dependency owners to the registry's canonical lowercase identity, so a clean consumer builds WiFiManager and its ESP8266/ESP32 transport dependencies without duplicating them in `lib_deps`. Remove the superseded include-path bridge.
+
+## 3.0.5
+
+- Add a library-owned PlatformIO bridge for the asynchronous web/TCP include paths required when WiFiManager is nested beneath DeviceFramework.
+
+## 3.0.4
+
+- Set the package's deep PlatformIO dependency-discovery mode so WiFiManager's asynchronous web/TCP children remain available when it is consumed through DeviceFramework.
+
+## 3.0.3
+
+- Declare the ESP8266 and ESP32 async TCP libraries explicitly in the PlatformIO package manifest so clean consumers resolve the headers required by the asynchronous portal.
+
+## 3.0.2
+
+- Update the pinned DFTE dependency to the iterator-lifecycle and configuration-safe 1.0.2 release.
+
+## 3.0.1
+
+- Redact WiFi, AP, portal-form, and custom-parameter values from diagnostic logs.
+
+## 3.0.0
+
+- Establish `device-framework` as the independently maintained canonical branch.
+- Add safe default parameter construction and allocation-failure handling.
+- Pin the DFTE dependency used by PlatformIO builds.

 # WiFiManager
-ESP8266 WiFi Connection manager with fallback web configuration portal
 
-[![Build Status](https://travis-ci.org/tzapu/WiFiManager.svg?branch=master)](https://travis-ci.org/tzapu/WiFiManager)
+WiFiManager gives ESP8266 and ESP32 firmware a polished, self-hosted Wi-Fi setup experience. It reconnects to saved networks and opens a temporary captive portal when it cannot, so users can configure the device from any phone or browser without a cloud service or companion app.
 
-The configuration portal is of the captive variety, so on various devices it will present the configuration dialogue as soon as you connect to the created access point.
+## See it on real hardware
 
-First attempt at a library. Lots more changes and fixes to do. Contributions are welcome.
+![A short WiFiManager portal tour showing product branding, nearby networks,
+application settings, and scan feedback.](docs/assets/readme/portal-tour.gif)
 
-#### This works with the ESP8266 Arduino platform with a recent stable release(2.0.0 or newer) https://github.com/esp8266/Arduino
+WiFiManager provides a self-hosted setup portal for Wi-Fi and application
+settings without copying portal HTML into each firmware. See the detailed
+[portal UI guide](docs/PORTAL_UI.md) for supported branding and content APIs.

+## Start with a working portal
 
-
-## How It Works
-- when your ESP starts up, it sets it up in Station mode and tries to connect to a previously saved Access Point
-- if this is unsuccessful (or no previous network saved) it moves the ESP into Access Point mode and spins up a DNS and WebServer (default ip 192.168.4.1)
-- using any wifi enabled device with a browser (computer, phone, tablet) connect to the newly created Access Point
-- because of the Captive Portal and the DNS server you will either get a 'Join to network' type of popup or get any domain you try to access redirected to the configuration portal
-- choose one of the access points scanned, enter password, click save
-- ESP will try to connect. If successful, it relinquishes control back to your app. If not, reconnect to AP and reconfigure.
-
-## How It Looks
-![ESP8266 WiFi Captive Portal Homepage](http://i.imgur.com/YPvW9eql.png) ![ESP8266 WiFi Captive Portal Configuration](http://i.imgur.com/oicWJ4gl.png)
-
-## Wishlist
-- ~~remove dependency on EEPROM library~~
-- ~~move HTML Strings to PROGMEM~~
-- ~~cleanup and streamline code~~ (although this is ongoing)
-- if timeout is set, extend it when a page is fetched in AP mode
-- ~~add ability to configure more parameters than ssid/password~~
-- ~~maybe allow setting ip of ESP after reboot~~
-- ~~add to Arduino Library Manager~~
-- ~~add to PlatformIO~~
-- add multiple sets of network credentials
-- ~~allow users to customize CSS~~
-
-## Quick Start
-
-### Installing
-You can either install through the Arduino Library Manager or checkout the latest changes or a release from github
-
-#### Install through Library Manager
-__Currently version 0.8+ works with release 2.0.0 or newer of the [ESP8266 core for Arduino](https://github.com/esp8266/Arduino)__
- - in Arduino IDE got to Sketch/Include Library/Manage Libraries
-  ![Manage Libraries](http://i.imgur.com/9BkEBkR.png)
-
- - search for WiFiManager
-  ![WiFiManager package](http://i.imgur.com/18yIai8.png)
-
- - click Install and start [using it](#using)
-
-####  Checkout from github
-__Github version works with release 2.0.0 or newer of the [ESP8266 core for Arduino](https://github.com/esp8266/Arduino)__
-- Checkout library to your Arduino libraries folder
-
-### Using
-- Include in your sketch
 ```cpp
-#include <ESP8266WiFi.h>          //ESP8266 Core WiFi Library (you most likely already have this in your sketch)
+#include <Arduino.h>
+#include <WiFiManager.h>
 
-#include <DNSServer.h>            //Local DNS Server used for redirecting all requests to the configuration portal
-#include <ESP8266WebServer.h>     //Local WebServer used to serve the configuration portal
-#include <WiFiManager.h>          //https://github.com/tzapu/WiFiManager WiFi Configuration Magic
-```
+WiFiManager wifi;
 
-- Initialize library, in your setup function add
-```cpp
-WiFiManager wifiManager;
-```
+void setup() {
+    Serial.begin(115200);
 
-- Also in the setup function add
-```cpp
-//first parameter is name of access point, second is the password
-wifiManager.autoConnect("AP-NAME", "AP-PASSWORD");
-```
-if you just want an unsecured access point
-```cpp
-wifiManager.autoConnect("AP-NAME");
-```
-or if you want to use and auto generated name from 'ESP' and the esp's Chip ID use
-```cpp
-wifiManager.autoConnect();
-```
+    // Leave the temporary setup portal available for three minutes.
+    wifi.setConfigPortalTimeout(180);
 
-After you write your sketch and start the ESP, it will try to connect to WiFi. If it fails it starts in Access Point mode.
-While in AP mode, connect to it then open a browser to the gateway IP, default 192.168.4.1, configure wifi, save and it should reboot and connect.
-
-Also see [examples](https://github.com/tzapu/WiFiManager/tree/master/examples).
-
-## Documentation
-
-#### Password protect the configuration Access Point
-You can and should password protect the configuration access point.  Simply add the password as a second parameter to `autoConnect`.
-A short password seems to have unpredictable results so use one that's around 8 characters or more in length.
-The guidelines are that a wifi password must consist of 8 to 63 ASCII-encoded characters in the range of 32 to 126 (decimal)
-```cpp
-wifiManager.autoConnect("AutoConnectAP", "password")
-```
-
-#### Callbacks
-##### Enter Config mode
-Use this if you need to do something when your device enters configuration mode on failed WiFi connection attempt.
-Before `autoConnect()`
-```cpp
-wifiManager.setAPCallback(configModeCallback);
-```
-`configModeCallback` declaration and example
-```cpp
-void configModeCallback (WiFiManager *myWiFiManager) {
-  Serial.println("Entered config mode");
-  Serial.println(WiFi.softAPIP());
-
-  Serial.println(myWiFiManager->getConfigPortalSSID());
+    // Reconnect to saved Wi-Fi, or open the setup portal when none works.
+    wifi.autoConnect("Device Setup", "change-me");
 }
-```
 
-##### Save settings
-This gets called when custom parameters have been set **AND** a connection has been established. Use it to set a flag, so when all the configuration finishes, you can save the extra parameters somewhere.
-
-See [AutoConnectWithFSParameters Example](https://github.com/tzapu/WiFiManager/tree/master/examples/AutoConnectWithFSParameters).
-```cpp
-wifiManager.setSaveConfigCallback(saveConfigCallback);
-```
-`saveConfigCallback` declaration and example
-```cpp
-//flag for saving data
-bool shouldSaveConfig = false;
-
-//callback notifying us of the need to save config
-void saveConfigCallback () {
-  Serial.println("Should save config");
-  shouldSaveConfig = true;
-}
-```
-
-#### Configuration Portal Timeout
-If you need to set a timeout so the ESP doesn't hang waiting to be configured, for instance after a power failure, you can add
-```cpp
-wifiManager.setConfigPortalTimeout(180);
-```
-which will wait 3 minutes (180 seconds). When the time passes, the autoConnect function will return, no matter the outcome.
-Check for connection and if it's still not established do whatever is needed (on some modules I restart them to retry, on others I enter deep sleep)
-
-#### On Demand Configuration Portal
-If you would rather start the configuration portal on demand rather than automatically on a failed connection attempt, then this is for you.
-
-Instead of calling `autoConnect()` which does all the connecting and failover configuration portal setup for you, you need to use `startConfigPortal()`. __Do not use BOTH.__
-
-Example usage
-```cpp
 void loop() {
-  // is configuration portal requested?
-  if ( digitalRead(TRIGGER_PIN) == LOW ) {
-    WiFiManager wifiManager;
-    wifiManager.startConfigPortal("OnDemandAP");
-    Serial.println("connected...yeey :)");
-  }
+    // Service portal requests and connection state without blocking firmware work.
+    wifi.process();
 }
 ```
-See example for a more complex version. [OnDemandConfigPortal](https://github.com/tzapu/WiFiManager/tree/master/examples/OnDemandConfigPortal)
 
-#### Custom Parameters
-You can use WiFiManager to collect more parameters than just SSID and password.
-This could be helpful for configuring stuff like MQTT host and port, [blynk](http://www.blynk.cc) or [emoncms](http://emoncms.org) tokens, just to name a few.
-**You are responsible for saving and loading these custom values.** The library just collects and displays the data for you as a convenience.
-Usage scenario would be:
-- load values from somewhere (EEPROM/FS) or generate some defaults
-- add the custom parameters to WiFiManager using
- ```cpp
- // id/name, placeholder/prompt, default, length
- WiFiManagerParameter custom_mqtt_server("server", "mqtt server", mqtt_server, 40);
- wifiManager.addParameter(&custom_mqtt_server);
+When saved Wi-Fi is unavailable, `autoConnect()` starts the portal asynchronously. Call `process()` from every `loop()` iteration while it may be open. Flash [Basic Portal](examples/BasicPortal/) to try this exact flow; its README gives the network name, password, portal address, and expected result after saving Wi-Fi.
 
- ```
-- if connection to AP fails, configuration portal starts and you can set /change the values (or use on demand configuration portal)
-- once configuration is done and connection is established [save config callback]() is called
-- once WiFiManager returns control to your application, read and save the new values using the `WiFiManagerParameter` object.
- ```cpp
- mqtt_server = custom_mqtt_server.getValue();
- ```  
-This feature is a lot more involved than all the others, so here are some examples to fully show how it is done.
-You should also take a look at adding custom HTML to your form.
+## Building a Home Assistant device?
 
-- Save and load custom parameters to file system in json form [AutoConnectWithFSParameters](https://github.com/tzapu/WiFiManager/tree/master/examples/AutoConnectWithFSParameters)
-- *Save and load custom parameters to EEPROM* (not done yet)
+WiFiManager remains a standalone provisioning library. If a device also needs
+persistent configuration, MQTT, Home Assistant discovery, OTA, mDNS, and an
+optional local web UI, see
+[DeviceFramework](https://github.com/alexhopeoconnor/DeviceFramework), which
+integrates this portal as part of that larger device lifecycle.
 
-#### Custom IP Configuration
-You can set a custom IP for both AP (access point, config mode) and STA (station mode, client mode, normal project state)
+## Make it yours
 
-##### Custom Access Point IP Configuration
-This will set your captive portal to a specific IP should you need/want such a feature. Add the following snippet before `autoConnect()`
 ```cpp
-//set custom ip for portal
-wifiManager.setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));
+const char kTitle[] PROGMEM = "Set up Temperature Monitor";
+const char kBrand[] PROGMEM = "Example Devices";
+const char kAccent[] PROGMEM = "#347a45";
+
+void setup() {
+    WiFiManagerPortalConfig portalUI;
+
+    // Leave fields unset to keep WiFiManager's built-in portal values.
+    portalUI.title = WiFiManagerPortalText::progmem(kTitle);
+    portalUI.identityText = WiFiManagerPortalText::progmem(kBrand);
+
+    // Theme values customise the built-in styles; they do not replace the portal.
+    portalUI.theme.accent = WiFiManagerPortalText::progmem(kAccent);
+    portalUI.theme.cornerRadiusPx = 10;
+
+    wifi.setPortalConfig(portalUI);  // Apply before the portal starts.
+    wifi.autoConnect("Device Setup");
+}
+
+void loop() {
+    wifi.process();
+}
 ```
 
-##### Custom Station (client) Static IP Configuration
-This will make use the specified IP configuration instead of using DHCP in station mode.
-```cpp
-wifiManager.setSTAStaticIPConfig(IPAddress(192,168,0,99), IPAddress(192,168,0,1), IPAddress(255,255,255,0));
-```
-There are a couple of examples in the examples folder that show you how to set a static IP and even how to configure it through the web configuration portal.
+The [Branded Portal](examples/BrandedPortal/) example includes a static SVG, accessible identity text, and a small semantic theme. [Custom Portal Content](examples/CustomPortalContent/) shows the supported parameters, information sections, and home cards without replacing the portal shell.
 
-#### Custom HTML, CSS, Javascript
-There are various ways in which you can inject custom HTML, CSS or Javascript into the configuration portal.
-The options are:
-- inject custom head element
-You can use this to any html bit to the head of the configuration portal. If you add a `<style>` element, bare in mind it overwrites the included css, not replaces.
-```cpp
-wifiManager.setCustomHeadElement("<style>html{filter: invert(100%); -webkit-filter: invert(100%);}</style>");
-```
-- inject a custom bit of html in the configuration form
-```cpp
-WiFiManagerParameter custom_text("<p>This is just a text paragraph</p>");
-wifiManager.addParameter(&custom_text);
-```
-- inject a custom bit of html in a configuration form element
-Just add the bit you want added as the last parameter to the custom parameter constructor.
-```cpp
-WiFiManagerParameter custom_mqtt_server("server", "mqtt server", "iot.eclipse", 40, " readonly");
+## What it provides
+
+- **Captive Wi-Fi setup:** starts an access point only when saved network credentials cannot connect.
+- **Responsive portal:** one small portal for Wi-Fi, application fields, information, actions, and firmware update flow.
+- **Structured APIs:** C++ configuration and a local JSON protocol for the built-in portal.
+- **Product presentation:** title, logo, tagline, and semantic colour tokens without copying the portal HTML.
+- **Primary and fallback networks:** an opt-in two-network controller backed by an application-provided store.
+- **ESP8266 and ESP32 support:** the package resolves its asynchronous web dependencies for the selected target.

 ```
 
-#### Filter Networks
-You can filter networks based on signal quality and show/hide duplicate networks.
+The suffix after `#` is a Git ref. PlatformIO clones the repository and checks out that release tag; GitHub Release assets are unrelated. Arduino IDE users can install this repository as a library checkout.
 
-- If you would like to filter low signal quality networks you can tell WiFiManager to not show networks below an arbitrary quality %;
-```cpp
-wifiManager.setMinimumSignalQuality(10);
-```
-will not show networks under 10% signal quality. If you omit the parameter it defaults to 8%;
-
-- You can also remove or show duplicate networks (default is remove).
-Use this function to show (or hide) all networks.
-```cpp
-wifiManager.setRemoveDuplicateAPs(false);
-```
-
-#### Debug
-Debug is enabled by default on Serial. To disable add before autoConnect
-```cpp
-wifiManager.setDebugOutput(false);
-```
-
-## Troubleshooting
-If you get compilation errors, more often than not, you may need to install a newer version of the ESP8266 core for Arduino.
-
-Changes added on 0.8 should make the latest trunk work without compilation errors. Tested down to ESP8266 core 2.0.0. **Please update to version 0.8**
-
-I am trying to keep releases working with release versions of the core, so they can be installed through boards manager, but if you checkout the latest version directly from github, sometimes, the library will only work if you update the ESP8266 core to the latest version because I am using some newly added function.
-
-If you connect to the created configuration Access Point but the configuration portal does not show up, just open a browser and type in the IP of the web portal, by default `192.168.4.1`.
-
-If trying to connect ends up in an endless loop, try to add `setConnectTimeout(60)` before `autoConnect();`. The parameter is timeout to try connecting in seconds.
-

+# API reference
+
+This is a task-oriented reference for the supported WiFiManager firmware API. Configure an instance during boot, keep it alive for the application's lifetime, and call process() regularly while WiFiManager may have active work.
+
+For complete end-to-end patterns, use [Provisioning lifecycle](PROVISIONING_LIFECYCLE.md), [Portal content](PORTAL_CONTENT.md), and [Station profiles](STATION_PROFILES.md).
+
+## Lifecycle
+
+| API | Timing and meaning |
+| --- | --- |
+| autoConnect([apName, apPassword]) | Tries legacy saved station credentials. Returns true if it connected during the call; otherwise starts the enabled portal fallback and returns false. |
+| startConfigPortal([apName, apPassword]) | Immediately starts a configuration AP and captive portal. |
+| stopConfigPortal() | Immediately stops the configuration portal. |
+| startWebPortal() / stopWebPortal() | Starts/stops the portal web server without the configuration-AP flow. |
+| process() | Cooperatively services active portal, scan, station-profile, and connection state. Call from loop(); do not treat it as a hard real-time operation or rely on a fixed maximum duration. |
+| getConfigPortalSSID() | Returns the current configuration AP name. |
+| getConfigPortalActive() / getWebPortalActive() | Reports active configuration or web portal state. |
+| setHttpPort(port) | Chooses the portal server port before starting it. |
+
+The application owns any existing HTTP service and must release a shared port before WiFiManager starts its portal.
+
+## Station profiles
+
+| API | Timing and meaning |
+| --- | --- |
+| setStationProfileStore(store) | Supplies an application-owned durable store; WiFiManager does not own it. |
+| startStationConnection([apName, apPassword]) | Loads and begins the stored primary/fallback profile flow. |
+| startStationCandidate(candidate[, apName, apPassword]) | Attempts an in-memory profile set; when a store is attached, saves it only after a successful usable connection. |
+| saveStationProfiles(profiles) | Deliberately stores a complete profile set without a connection verification attempt. |
+| clearStationProfiles() | Clears the store and disconnects the station. |
+| setStationRecoveryInterval(milliseconds) | Sets delay before profile recovery attempts after a connection loss. |
+| isStationProfileMode(), getStationProfiles(), getStationStatus() | Inspects profile-controller state. |
+
+Profile mode has exactly primary slot 0 and optional fallback slot 1. See [Station profiles](STATION_PROFILES.md) for storage rules and portal fields.
+
+## Application settings and callbacks
+
+| API | Timing and meaning |
+| --- | --- |
+| portalAddParameter(parameter) | Registers an application-owned WiFiManagerParameter; it must outlive the portal. Returns false if registration fails. |
+| portalClearParameters() | Removes registered parameter pointers; it does not delete them. |
+| getParameters() / getParametersCount() | Inspects registered parameters. |
+| setPreSaveParamsCallback(callback) | Invoked before a parameter-only save. |
+| setSaveParamsCallback(callback) | Invoked when parameters save; receives WiFiManagerRequestArgs. |

+| setSaveConfigCallback(callback) | Invoked after changed Wi-Fi settings connect successfully, or when break-after-config is enabled. |
+| setConfigResetCallback(callback) | Invoked when Wi-Fi settings reset. |
+| setAPCallback(callback) / setWebServerCallback(callback) | Invoked after the AP/config portal or web server begins. |
+| setConfigPortalTimeoutCallback(callback) | Invoked when a configuration portal times out. |
+| setPreOtaUpdateCallback(callback) | Invoked immediately before OTA update handling. |
+
+WiFiManagerRequestArgs provides hasArg(), getArg(), getArgAsInt(), getArgAsFloat(), getArgAsBool(), and count(). It is a callback argument, not durable application configuration.
+
+WiFiManagerParameter constructors accept an ID, label, default value, maximum length, optional custom HTML, and optional label placement. IDs are request field names; keep them stable and simple.
+

+| portalAddInfoSection(), portalClearInfoSections() | Adds/clears copied read-only information sections. |
+| portalAddHomeCard(), portalClearHomeCards() | Adds/clears copied overview cards. |
+
+Use [Portal UI and configuration](PORTAL_UI.md) for configuration examples and [Portal content](PORTAL_CONTENT.md) for ownership/persistence rules.
+
+## Connection and network policy
+
+| API | Timing and meaning |
+| --- | --- |
+| setConfigPortalTimeout(seconds) | Limits configuration portal lifetime; setTimeout() is deprecated alias. |
+| setConnectTimeout(seconds), setConnectRetries(count) | Bounds legacy automatic connection attempts. |
+| setSaveConnectTimeout(seconds), setSaveConnect(enabled) | Controls and bounds portal save-and-connect behavior. |

+| setRestorePersistent(enabled) | Controls restoration of the platform Wi-Fi persistence setting. |
+
+See [Network configuration](NETWORK_CONFIGURATION.md) for deployment constraints.
+
+## Scan, state, and diagnostics
+
+| API | Timing and meaning |
+| --- | --- |
+| requestAsyncScan(forceRefresh) | Requests a non-blocking scan. |
+| getScanSnapshot(), getScanRuntimeState(), getScanState() | Returns scan lifecycle state. |
+| isScanRunning(), hasValidScanResults() | Reads scan progress and cached-result validity. |
+| getScanResults() | Returns WiFiManager-owned cached visible results; do not retain references after a new scan or portal shutdown. |
+| getRSSIasQuality(rssi) | Converts RSSI to WiFiManager quality. |
+| getLastConxResult(), getWLStatusString(), getModeString() | Formats connection and mode diagnostics. |
+| hasEnteredConfigPortal(), getConfigPortalConnectState() | Reads portal-session history and last submission state. |

+## Reset and low-level helpers
+
+| API | Meaning |
+| --- | --- |
+| disconnect() | Disconnects without erasing saved configuration. |
+| resetSettings() | Clears legacy Wi-Fi settings. |
+| erase([optional]) | Erases Wi-Fi configuration. |
+| reboot() | Reboots the target. |
+| getWiFiIsSaved(), getWiFiSSID(), getWiFiPass() | Reads legacy saved/current station values; handle credentials carefully. |
+| getDefaultAPName() | Returns the default generated AP name. |
+| debugSoftAPConfig(), debugPlatformInfo() | Writes diagnostic information. |
+| htmlEntities(text[, whitespace]) | Escapes text for WiFiManager HTML rendering. |
+| preloadWiFi(ssid, password) | Intended for fixtures or controlled integrations that deliberately skip normal station configuration. |
+
+getServer() and getDNSServer() are exposed for testing/host integration. They are not a supported way for product firmware to add private portal routes or mutate the built-in server.

+# Integrating WiFiManager
+
+WiFiManager runs device-local Wi-Fi setup. It tries station Wi-Fi, temporarily
+hosts an access point and portal when the device cannot connect, and then lets
+the firmware continue its normal work. It is not a cloud service,
+remote-management system, or companion-app framework.
+
+## What WiFiManager handles
+
+| WiFiManager handles | Your firmware handles |
+| --- | --- |
+| Temporary AP, captive DNS, portal routes, Wi-Fi connection attempts, portal session state | Durable application settings, schema migration, product services, LEDs/display, reboot policy, telemetry, and access-control decisions |
+| Wi-Fi credentials in the legacy flow, or profile-selection policy in station-profile mode | The durable station-profile store when profile mode is enabled |
+| Structured portal presentation and built-in Wi-Fi/settings forms | Product-specific validation and the persistence of product settings |
+| The local portal JSON protocol | Any separate product HTTP API or local web server |
+
+This lets a firmware decide what configuration it needs without copying the
+portal, captive-network behavior, or Wi-Fi connection flow.
+
+## Typical boot sequence
+
+~~~text
+Firmware boot
+  │
+  ├─ Load and migrate application settings
+  ├─ Register portal branding, policy, and application parameters
+  ├─ Start a WiFiManager connection flow
+  │    ├─ Connected: start normal application services
+  │    └─ Not connected: temporary AP + local portal
+  ├─ Service wifi.process() while a portal or profile controller is active
+  └─ Persist application data and decide when to restart or resume services
+~~~
+
+Register portal configuration before calling autoConnect(), startConfigPortal(), startWebPortal(), or a station-profile start method. The active portal uses an immutable response model so that asynchronous requests cannot see a partially changed UI.
+
+## Customise the built-in portal
+
+WiFiManager can set product identity, named theme values, page/action
+visibility, parameters, information sections, and home cards. Use its public
+C++ configuration and content APIs for those tasks:
+
+~~~cpp
+WiFiManagerPortalConfig portal;
+portal.title = WiFiManagerPortalText::progmem(PSTR("Set up sensor"));
+wifi.setPortalConfig(portal);
+~~~
+
+The built-in portal still owns its HTML shell, routes, forms, navigation, and
+captive behavior. It does not provide:
+
+- arbitrary portal HTML-shell replacement;
+- raw CSS or JavaScript injection;
+- route replacement or navigation injection;
+- a cloud API or supported mobile-companion integration surface.
+
+The `/api/*` routes are the built-in portal's browser protocol. They are useful
+for portal maintenance and tests, but are not a product firmware or
+companion-app integration API. If a product needs a reusable portal capability,
+add one focused public WiFiManager C++ API and test it on ESP8266 and ESP32.
+
+## Application-service handoff
+
+WiFiManager's portal server uses its configured HTTP port, 80 by default. A product already using that port must explicitly release it before WiFiManager starts a portal. Conversely, the application decides when its normal web service is safe to start after a successful connection.
+
+Release an application-owned server before starting the portal:
+
+~~~cpp
+void beginRecovery() {
+    stopApplicationWebServer();       // Releases port 80 owned by the product.
+    wifi.startConfigPortal("Device Setup", "setup-password");
+}
+~~~
+
+The application may instead use a different WiFiManager HTTP port through setHttpPort(); document that address for installers because the captive-portal redirect and station handoff will include the selected port.
+
+## Data lifetime and persistence
+
+WiFiManagerPortalConfig text and SVG values are non-owning. Keep RAM or PROGMEM source data alive for the entire firmware lifetime. WiFiManagerParameter instances are application-owned and must outlive the portal. Portal information sections and home cards are copied when registered.
+
+A station-profile store is also application-owned. Its load(), save(), and clear() methods are responsible for durable storage and error handling. The profile controller chooses and verifies networks; it does not own the store or an application's migration format.
+
+## Security and operator expectations
+
+The configuration portal is intended for local setup. Use a Wi-Fi-valid AP password in deployed products, do not put secrets in information cards or logs, and do not expose password placeholders unless there is an explicit local-installation requirement. The portal's JSON endpoints are the built-in UI's device-local protocol; they are not an authenticated remote-management API.

+# Development and releases
+
+Released consumers use the public Git tag. While changing WiFiManager and a sibling dependency together, point an ignored local PlatformIO override at a `symlink://` or `file://` checkout rather than changing tracked application dependencies.
+
+```ini
+lib_deps =
+    WiFiManager=symlink:///path/to/WiFiManager
+```
+
+## Target pins
+
+WiFiManager uses one maintained ESP32 test lane:
+
+| Lane | pioarduino platform | Purpose |
+| --- | --- | --- |
+| `esp32` | `55.03.311` / Arduino-ESP32 3.3.11 | maintained baseline |
+
+This is a test-target policy, not a library-manifest dependency: a consuming
+application chooses its own `platform` and must validate the complete
+framework/toolchain stack. Do not let a shared global PlatformIO cache choose
+framework metadata or a compiler implicitly, and do not override just the
+toolchain to repair a cache mismatch. Each pioarduino platform owns its
+matching framework, uploader, and compiler package set.
+
+Core 3 Wi-Fi builds need the C++14, `SOC_WIFI_SUPPORTED`, and `Network/src`
+settings in this repository's `platformio.ini`; keep those settings together
+when adding an ESP32 environment. The portal OTA fixture and every guided
+example use this 3.3.11 ESP32 baseline.
+
+ESP8266 test environments pin framework commit `521ae60` for the upstream
+Postmortem large-jump linker fix. The exact rationale and update rule are in
+the shared [ESP8266 linker-workaround note](https://github.com/alexhopeoconnor/arduino-home-assistant/blob/main/docs/ESP8266-LINKER-WORKAROUND.md).
+For the pioarduino release-to-Core mapping and cache-collision diagnosis, see
+[DeviceFramework's toolchain guide](https://github.com/alexhopeoconnor/DeviceFramework/blob/main/docs/TOOLCHAINS.md).
+
+`./scripts/test.sh` and `./tools/portal-hardware ota --platform esp32` use the
+PlatformIO Core/cache shared by the maintained framework repositories,
+defaulting to `${XDG_CACHE_HOME:-$HOME/.cache}/arduino-framework-platformio/core-3.3.11`.
+WiFiManager, DeviceFramework, DFTE, and ArduinoHA pin this same graph, so this
+avoids downloading the same Core 3.3.11 inputs for each repository while
+keeping pioarduino's package-form `esptool` and generated environment separate
+from stale global `tool-esptoolpy` metadata. Override the location with
+`WIFIMANAGER_PLATFORMIO_CORE_DIR`,
+`WIFIMANAGER_PLATFORMIO_PACKAGES_DIR`, and
+`WIFIMANAGER_PLATFORMIO_CACHE_DIR` when space belongs elsewhere or an isolated
+diagnosis is needed. The first shared install is several GiB; reserve at least
+4 GiB plus cache headroom. It is persistent and is never cleared by normal test
+commands.
+
+For a disposable cache investigation, point that variable at an exact temporary
+directory, run the affected command, inspect the resolved graph, then remove
+only that directory:
+
+```bash
+wm_pio_core="$(mktemp -d /tmp/wifimanager-pio-XXXXXX)"
+WIFIMANAGER_PLATFORMIO_CORE_DIR="$wm_pio_core" \
+  ./scripts/test.sh compile --platform esp32
+rm -rf -- "$wm_pio_core"
+```
+
+Start a release with `bump-version.sh`. It updates package metadata and canonical installation snippets, then creates the changelog section. Replace its generated TODO with the release summary and update any behavioural documentation before running:
+
+```bash
+./scripts/bump-version.sh vMAJOR.MINOR.PATCH
+# Replace the generated CHANGELOG TODO with the release summary.
+./scripts/check-docs.sh
+./scripts/test.sh compile --platform esp8266
+./scripts/test.sh compile --platform esp32
+./scripts/test.sh unity --platform esp8266
+./scripts/test.sh unity --platform esp32
+./scripts/test.sh examples --platform esp8266
+./scripts/test.sh examples --platform esp32
+./scripts/test.sh ota-fixtures --platform esp8266
+./scripts/test.sh ota-fixtures --platform esp32
+./scripts/prepare-release.sh vMAJOR.MINOR.PATCH --tag
+```
+
+When a physical ESP8266 and ESP32 are available, include their local lifecycle tests in the release gate. These tests remain opt-in because they flash the selected board and use its actual radio:
+
+~~~bash
+./scripts/test.sh hardware --platform esp8266 --port /dev/serial/by-id/usb-...
+./scripts/test.sh hardware --platform esp32 --port /dev/serial/by-id/usb-...
+~~~
+
+When a physical ESP8266 or ESP32 and a spare USB Wi-Fi adapter are available,
+run the Docker portal test harness as an additional release-gate check. It is
+opt-in because it flashes the selected board and temporarily joins its AP, but
+it refuses the host default-route adapter and leaves Docker responsible only
+for browser/API testing:
+
+```bash
+./tools/portal-hardware run --platform esp8266 --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165
+```
+
+From an SSH/headless shell, the portal command may ask once for scoped
+NetworkManager sudo authorization before the selected board is erased. This is
+host setup, not a test secret; never add a sudo value to an env file or run the
+whole runner as root. See [Testing](TESTING.md#networkmanager-authorization)
+for the direct/Polkit and scoped-sudo behavior.
+
+See [Testing](TESTING.md#docker-portal-test-harness) for cleanup, artifacts, and
+optional station handoff credentials.
+
+Run the portal HTTP OTA A/B test harness separately when a spare adapter and 4 MB
+test board are available. It erases the selected board's flash, serial-flashes
+A, and uses the real browser update form to upload B; do not replace its
+automatic-reboot assertion with a manual reset:
+
+```bash
+./tools/portal-hardware ota --platform esp8266 --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165
+```
+
+See [Portal HTTP OTA A/B test harness](TESTING.md#portal-http-ota-ab-test-harness) for
+the partition, artifact, final-board-state, and adapter rules.
+
+Push the branch and annotated tag. GitHub Actions repeats the board-free compile checks, validates the package, and creates a GitHub Release using that version’s changelog section. The workflow does not publish to the PlatformIO Registry.

+# Getting started
+
+WiFiManager owns station credential recovery and a temporary configuration portal. Keep one instance for the life of the application.
+
+```cpp
+#include <Arduino.h>
+#include <WiFiManager.h>
+
+WiFiManager wifi;
+
+void setup() {
+    Serial.begin(115200);
+    wifi.setConfigPortalTimeout(180);  // Stop the portal after three minutes.
+    wifi.autoConnect("Example Setup", "change-me");
+}
+
+void loop() {
+    wifi.process();  // Keeps the portal responsive when setup is needed.
+    // Normal work begins after autoConnect succeeds.
+}
+```
+
+`autoConnect()` first tries stored station credentials. If that cannot connect, it starts the AP and portal with the supplied name and password, then returns `false`; call `process()` from `loop()` so that portal can run. `setConfigPortalTimeout(180)` limits that portal to three minutes; pass `0` (the default) to leave it open. Use a Wi-Fi-valid AP password.
+
+## PlatformIO dependency
+
+```ini
+lib_deps =
+    WiFiManager=https://github.com/alexhopeoconnor/WiFiManager.git#v3.2.5
+```
+
+The package includes the asynchronous web and TCP dependencies required by the selected ESP8266 or ESP32 target. Add WiFiManager as the application’s direct dependency; do not copy its internal dependency list into your project.
+
+Next: build [Basic Portal](../examples/BasicPortal/), then read [Provisioning lifecycle](PROVISIONING_LIFECYCLE.md) for return-state, timeout, and recovery rules.

+# Network configuration
+
+These APIs configure WiFiManager's AP, station, scan, and reconnection behavior. Set them during boot, before starting a connection or portal flow, so an installer sees one consistent configuration.
+
+The current ESP8266 and ESP32 implementations apply AP static addressing through WiFi.softAPConfig() and station static addressing through WiFi.config(). Station static configuration is used by legacy connections, portal save-and-connect attempts, and the station-profile controller.
+
+This page is an advanced deployment reference. Use these settings only when the local network and the product's operating policy require them; WiFiManager's defaults are appropriate for many devices.
+
+## Access-point setup network
+
+| API | Purpose |
+| --- | --- |
+| setWiFiSSIDPrefix(prefix) | Changes the prefix used by an automatically generated AP name. |
+| setWiFiAPChannel(channel) | Selects the setup AP Wi-Fi channel. |
+| setWiFiAPHidden(hidden) | Hides or advertises the setup AP SSID. |
+| setAPStaticIPConfig(ip, gateway, subnet) | Sets the AP-side portal address configuration. |
+| setHttpPort(port) | Uses a non-default portal HTTP port. |
+| setHostname(name) | Sets the station/AP hostname as supported by the target. |
+| getConfigPortalSSID() / getDefaultAPName() | Reports the actual/current setup AP name. |
+
+A hidden AP can make field setup harder because an installer must enter the SSID manually. Treat it as a deployment decision, not a general security control. If setHttpPort() changes the default, publish the full portal address in the product's installation procedure.
+
+## A fixed setup-portal address
+
+Give the setup AP a fixed address when an installer procedure needs a stable local portal address:
+
+~~~cpp
+wifi.setAPStaticIPConfig(
+    IPAddress(192, 168, 8, 1),
+    IPAddress(192, 168, 8, 1),
+    IPAddress(255, 255, 255, 0));
+wifi.setWiFiAPChannel(6);
+wifi.setWiFiAPHidden(false);
+~~~
+
+This is applied before WiFiManager starts its SoftAP. The usual portal address becomes http://192.168.8.1/. If setHttpPort() selects a non-default port, include that port in the installer instructions and expect the station handoff URL to include it too.
+
+## Station address and credential behavior
+
+Use a station static address only when the network owner has reserved and documented it:
+
+~~~cpp
+wifi.setSTAStaticIPConfig(
+    IPAddress(192, 168, 20, 50),
+    IPAddress(192, 168, 20, 1),
+    IPAddress(255, 255, 255, 0),
+    IPAddress(192, 168, 20, 1));
+~~~
+
+| API | Purpose |
+| --- | --- |
+| setSTAStaticIPConfig(ip, gateway, subnet[, dns]) | Supplies a station static address and optional DNS server. |
+| setCleanConnect(enabled) | Disconnects before connecting; use when the product requires a fresh association. |
+| setRestorePersistent(enabled) | Controls restoration of the platform Wi-Fi persistence preference. |
+| setWiFiAutoReconnect(enabled) | Enables Wi-Fi auto-reconnect behavior. |
+| setCountry(countryCode) | Applies the supported Wi-Fi country setting. |
+| disconnect() | Disconnects without erasing persistent settings. |
+| resetSettings() | Clears legacy saved Wi-Fi settings. |
+| erase([optional]) | Erases Wi-Fi configuration and schedules the configured reset behavior. |
+
+Static-IP entry fields can be configured independently of the network setting:
+
+~~~cpp
+wifi.portalSetFieldStaticIpVisibility(PortalFieldVisibility::Auto);
+wifi.portalSetFieldStaticDnsVisibility(PortalFieldVisibility::Hidden);
+~~~
+
+Auto shows these fields when a static station configuration is already in use; Always makes them visible; Hidden suppresses them. Do not expose static network controls in a general user portal unless the installer is expected to manage those values.
+
+## Scan behavior
+
+WiFiManager's portal schedules asynchronous scans. Firmware that needs its own nearby-network status can request and inspect the same cached scan state:
+
+~~~cpp
+wifi.requestAsyncScan();
+
+if (wifi.hasValidScanResults()) {
+    for (const auto& network : wifi.getScanResults()) {
+        Serial.printf("%s: %ld dBm\n", network.ssid.c_str(), network.rssi);
+    }
+}
+~~~
+
+| API | Purpose |
+| --- | --- |
+| requestAsyncScan(forceRefresh) | Queues a scan without blocking the application loop. |
+| getScanSnapshot() / getScanRuntimeState() | Returns the complete scan lifecycle snapshot. |
+| getScanState() / isScanRunning() / hasValidScanResults() | Provides concise status checks. |
+| getScanResults() | Returns the cached visible network list. |
+| setMinimumSignalQuality(quality) | Filters low-quality scan results. |
+| setRemoveDuplicateAPs(enabled) | Controls duplicate SSID removal. |
+| setScanDispPerc(enabled) | Uses percentage rather than quality icons in the portal. |
+| getRSSIasQuality(rssi) | Converts RSSI for display. |
+
+WiFiManager owns the scan cache. It keeps the cache and its allocation while a portal is active so nearby networks can be rendered without repeated allocation churn; it clears and releases that storage when the portal fully closes. Treat getScanResults() as a snapshot and do not retain references, iterators, or pointers across a new scan or portal shutdown.
+
+## Connection and timeout policy
+
+See [Provisioning lifecycle](PROVISIONING_LIFECYCLE.md) for setConfigPortalTimeout(), setConnectTimeout(), setConnectRetries(), setSaveConnectTimeout(), setSaveConnect(), and the portal-prefixed behavior equivalents. These settings define recovery behavior; they should reflect how long an on-site installer can reasonably work and how long the product can remain offline.

+| getConfigPortalConnectMessage() | Human-readable status; suitable for logs or local display. |
+| getLastConxResult() / getWLStatusString() | Legacy and general Wi-Fi connection result helpers. |
+
+Use these values to drive product feedback. Do not derive state by scraping portal HTML or assuming that an autoConnect() false return means the portal session failed.
+
+## Events
+
+setEventCallback() installs an optional notification hook:
+
+~~~cpp
+wifi.setEventCallback([](WiFiManager::wm_event_t event) {
+    switch (event) {
+        case WiFiManager::WM_EVENT_PORTAL_STARTED:
+            setIndicator(IndicatorState::Setup);
+            break;
+        case WiFiManager::WM_EVENT_PORTAL_CONNECT_SUCCESS:
+            setIndicator(IndicatorState::ConnectingComplete);
+            break;
+        case WiFiManager::WM_EVENT_STATION_LINK_LOST:
+            setIndicator(IndicatorState::Offline);
+            break;
+        default:
+            break;
+    }
+});
+~~~
+
+| Event | Product use |
+| --- | --- |
+| WM_EVENT_PORTAL_STARTED / WM_EVENT_PORTAL_STOPPED | Begin or end setup feedback. |
+| WM_EVENT_PORTAL_CONNECT_QUEUED / START / SUCCESS / FAILED | Show progress and result for a portal-submitted network. |
+| WM_EVENT_STATION_PROFILE_ATTEMPT / CONNECTED / FAILED | Track profile-controller progress. |
+| WM_EVENT_STATION_LINK_LOST / BACKOFF | Show recovery behavior after an established connection drops. |
+| WM_EVENT_STATION_PROFILES_CLEARED | Reconcile product state after profiles are cleared. |
+
+Events are intentionally small and do not carry credentials or mutable request state. Read the relevant getter inside the callback when more detail is needed.
+
+## Station-profile status
+
+When using profile mode, getStationStatus() reports:
+
+- state: idle, loading, attempting, switching, connected, backoff, or portal;
+- activeSlot and attemptedSlot;
+- configuredProfiles;
+- wifiStatus and a human-readable message;
+- whether the last connection was a candidate;
+- whether the profile store could not save a successful candidate.
+
+A store-save failure is operationally important: the device may be connected now but will not necessarily reconnect after a restart. Preserve that distinction in an LED, display, or operator log.
+
+## Logging
+
+WiFiManager logs to its configured Print output unless a WiFiManagerLogSink is supplied.
+
+~~~cpp
+wifi.setLogPrefix("[network] ");
+wifi.setLogOutput(true, WiFiManagerLogLevel::Info);
+~~~
+
+WiFiManagerLogLevel ranges from Silent through Error, Warn, Info, Debug, and Trace. A custom WiFiManagerLogSink receives a WiFiManagerLogMessage instead of the Print output. Redact SSIDs and never log passwords, portal form values, or product secrets into a remotely collected log.
+
+## Scan status
+
+For nearby-network progress, use getScanState(), isScanRunning(), hasValidScanResults(), and getScanResults(); see [Network configuration](NETWORK_CONFIGURATION.md#scan-behavior). The portal API exposes a matching local scan-status representation for the built-in UI.

+# Built-in portal browser protocol
+
+This device-local protocol is used by WiFiManager's built-in portal shell. It
+is useful when maintaining that UI or writing portal-focused tests. It is not a
+cloud API, remote-management interface, or supported companion-app integration
+surface.
+
+The portal is unauthenticated local setup infrastructure. Do not expose it as a product's general application API, and do not infer a security boundary from hiding an action in the UI.
+
+## Contract version and format
+
+GET /api/bootstrap returns contractVersion 3. The built-in portal uses that versioned response; tests that assert its shape should feature-detect fields rather than assume undocumented portal HTML or JSON properties.
+
+All documented API responses are JSON with no-cache headers. The server also sends permissive CORS headers for the built-in portal implementation; that does not change the local-only security boundary or make these routes a remote integration contract.
+
+## Route inventory
+
+| Method | Route | Built-in portal purpose |
+| --- | --- | --- |
+| GET | / | Serves the one portal HTML shell. |
+| GET | /api/bootstrap | Reads product brand, portal context, page/action visibility, layout, scan summary, and overview cards. |
+| GET | /api/wifi/scan-status | Reads async scan state and visible nearby networks. |
+| POST | /api/wifi/scan | Queues a forced asynchronous scan; returns 202. |
+| GET | /api/wifi/meta | Reads Wi-Fi form fields, static-IP fields, parameters on the Wi-Fi page, and profile metadata when enabled. |
+| POST | /api/wifi/save | Submits Wi-Fi fields, applicable parameters, and optionally a station-profile set. |
+| GET | /api/wifi/connect-status | Reads the result of the most recent portal save-and-connect attempt. |
+| POST | /api/wifi/connect-complete | Acknowledges that the built-in portal has received the successful station handoff address. |
+| POST | /api/portal/timeout-reset | Restarts an active configured portal timeout. |
+| GET | /api/params | Reads parameters for the separate Setup page. |
+| POST | /api/params/save | Saves Setup-page parameters. |
+| GET | /api/info | Reads device/Wi-Fi info, copied information sections, and visible actions. |
+| GET | /api/status | Reads a short plain-text status summary in JSON. |
+| POST | /api/device/restart | Schedules a target restart. |
+| POST | /api/device/erase | Erases Wi-Fi configuration and schedules restart when successful. |
+| POST | /api/portal/close | Disables captive-portal detection for the active session. |
+| POST | /api/portal/exit | Requests portal exit when portal exit is allowed. |
+| POST | /u | Receives multipart firmware upload and returns JSON completion status. |
+
+Unknown routes are redirected only while captive-portal handling is active; otherwise they return the normal not-found result.
+
+## Bootstrap and read models
+
+Bootstrap includes a brand object (title, tagline, logo SVG, and logo alt text), a context object (portal activity, timeout remaining, identity text, status summary, scan state), visible pages/actions, parameter layout, and copied home cards.
+
+Wi-Fi form metadata is intentionally separate:
+
+- Legacy mode returns SSID/password fields, configured static fields, and parameters when the layout places them on the Wi-Fi page.
+- Profile mode returns primary/fallback profile metadata, the active slot, controller state, static fields, and applicable parameters.
+- Password values are never returned. Legacy password placeholder behavior is controlled by portalSetFieldPasswordPlaceholderMode().
+
+GET /api/params exposes all registered parameters for the separate Setup page, plus whether the back action is visible. GET /api/info exposes device/Wi-Fi facts, copied information sections, and action visibility. GET /api/status returns a short human-readable text field.
+
+## Wi-Fi submit and connection handoff
+
+POST /api/wifi/save accepts form fields. In legacy mode:
+
+| Field | Meaning |
+| --- | --- |
+| s | Station SSID. |
+| p | Station password. A password without an SSID is treated as a password change for the stored SSID. |
+| ip, gw, sn, dns | Optional station static IP, gateway, subnet, and DNS values when those fields are visible. |
+| Registered parameter ID or param_N | Application parameter values when parameters are placed on the Wi-Fi page. |
+
+A normal accepted save returns 202 and directs the portal to poll /api/wifi/connect-status. The status response is:
+
+~~~json
+{
+  "state": "success",
+  "message": "human readable status",
+  "wifiStatus": "WL_CONNECTED",
+  "stationIp": "192.168.1.42",
+  "redirectUrl": "http://192.168.1.42/"
+}
+~~~
+
+`state` is one of `idle`, `waiting`, `success`, or `failed`. The example shows
+a successful join; `stationIp` and `redirectUrl` are present only in that state.
+If the portal server is not on port 80, `redirectUrl` includes that port. When
+connect-on-save is disabled, a saved configuration has no station address and
+the built-in portal remains open.
+
+After observing success, the built-in portal POSTs /api/wifi/connect-complete. A 409 response means successful handoff is not ready; otherwise WiFiManager keeps the portal alive briefly, receives the acknowledgement, and then closes after a grace delay. Browser captive redirects can still fail, so the portal keeps the station address visible.
+
+When portalSetBehaviorConnectOnSave(false) or setSaveConnect(false) is selected, a Wi-Fi save does not start this station connection/handoff flow.
+
+## Profile-mode submit
+
+In profile mode, POST /api/wifi/save accepts s0/p0 for primary and s1/p1 for fallback. Primary must be non-empty. A blank p0 or p1 preserves an existing password; clear0 or clear1 explicitly clears a password for an open network.
+
+By default, WiFiManager attempts the submitted candidate and returns 202 for status polling. With stationAction=save, it writes the submitted profile set for a later connection attempt and returns 200. See [Station profiles](STATION_PROFILES.md) for candidate verification and storage behavior.
+
+## Parameter submit
+
+POST /api/params/save sends registered application parameter fields and returns a successful acknowledgement after the registered save callbacks run. A parameter can be addressed by its stable ID or by param_N index. WiFiManager does not define application validation or durable-storage semantics; the consuming application owns both.
+
+## Actions and error states
+
+| Route | Success | Important non-success response |
+| --- | --- | --- |
+| POST /api/wifi/scan | 202 with accepted/queued state | Scan result arrives through scan-status. |
+| POST /api/wifi/save | 202 for queued connection, or 200 for profile save-for-later | 400 for invalid Wi-Fi/profile input; 500 when an explicit profile store save fails. |
+| POST /api/wifi/connect-complete | 200 after successful station handoff | 409 when success/address is not ready. |
+| POST /api/portal/timeout-reset | 200 with timeout seconds remaining | 409 when no active finite portal timeout exists. |
+| POST /api/device/restart | 200, restart scheduled | The target restarts shortly after the response. |
+| POST /api/device/erase | 200, erase/restart scheduled | 500 when erase fails. |
+| POST /api/portal/close | 200, captive detection disabled | The portal server itself remains subject to its normal lifecycle. |
+| POST /api/portal/exit | 200, exit scheduled | 403 when exit is not allowed. |
+| POST /u | 200, firmware update/restart scheduled | 500 with update failure detail. |
+
+## Using this protocol safely
+
+Use this document to understand and test WiFiManager's own portal behavior.
+Applications that need a product web API should host and secure that API after
+WiFiManager has completed its provisioning role. Do not scrape the portal shell,
+depend on undocumented JSON fields, or add routes through WiFiManager's testing
+server accessor.

+# Portal content and application settings
+
+Use the built-in portal to collect small product settings alongside Wi-Fi credentials. WiFiManager owns the form and its temporary values; the application validates and persists its own settings.
+
+This matches the product-firmware pattern used by real consumers: load configuration first, expose its current values through WiFiManagerParameter objects, then persist valid submitted values through the application's configuration layer.
+
+## End-to-end pattern
+
+~~~cpp
+#include <WiFiManager.h>
+
+constexpr int kBrokerHostLength = 64;
+
+WiFiManager wifi;
+WiFiManagerParameter brokerHost(
+    "broker_host", "MQTT broker", "", kBrokerHostLength);
+
+void setupPortal() {
+    // The application has already loaded settings before this point.
+    brokerHost.setValue(settings.mqttHost.c_str(), kBrokerHostLength);
+    wifi.portalAddParameter(&brokerHost);
+
+    wifi.setSaveParamsCallback([](WiFiManager::WiFiManagerRequestArgs) {
+        const String candidate = brokerHost.getValue();
+
+        if (!isValidHostname(candidate)) {
+            logInvalidBroker(candidate);
+            return;  // Keep the application's known-good stored value.
+        }
+
+        settings.mqttHost = candidate;
+        saveApplicationSettings(settings);
+    });
+}
+~~~
+
+Call setupPortal() after loading application settings and before a WiFiManager connection or portal start method. The callback receives a copy of the submitted request arguments; use getArg(), getArgAsInt(), getArgAsFloat(), or getArgAsBool() when the application needs request-level values.
+
+The save-parameters callback is a notification hook, not a validation-response API. Its return type cannot turn the built-in UI's success response into a form error. Validate before using the candidate, preserve known-good data when persistence fails, and provide product-specific feedback through the application's own UI/logging policy.
+
+## Parameter rules
+
+| Rule | Why it matters |
+| --- | --- |
+| Keep each WiFiManagerParameter alive while the portal can use it. | WiFiManager stores the parameter pointer; it does not take ownership. |
+| Use a stable ID without spaces or special characters. | The ID is used in portal requests. |
+| Choose a bounded value length. | It defines the editable buffer length. |
+| Register parameters before opening the portal. | Active portal responses use their established form model. |
+| Treat submitted text as untrusted application input. | Portal input is not application validation or durable storage. |
+
+Use portalClearParameters() only before opening a portal when rebuilding a complete form. It removes registered parameter pointers; it does not destroy application-owned parameter objects.
+
+## Where settings appear
+
+By default, custom parameters appear on the Wi-Fi page. To put them on the separate Setup page:
+
+~~~cpp
+wifi.portalSetLayoutParamsLocation(PortalParamsLocation::SetupPage);
+~~~
+
+Use the Wi-Fi page for a small setting that is naturally provisioned with network credentials. Use the Setup page when product configuration needs its own step. Page visibility and layout are part of the structured portal policy; see [Portal UI and configuration](PORTAL_UI.md).
+
+## Read-only product context
+
+Use information sections for labelled facts and home cards for a short overview or callout:
+
+~~~cpp
+PortalInfoSection deviceInfo;
+deviceInfo.id = "device";
+deviceInfo.title = "Device";
+deviceInfo.items = {
+    {"firmware", "Firmware", firmwareVersion},
+    {"sensor", "Sensor", sensorReady ? "Ready" : "Checking"},
+};
+wifi.portalAddInfoSection(deviceInfo);
+
+PortalHomeCard installerHint;
+installerHint.id = "installer-hint";
+installerHint.title = "Before you begin";
+installerHint.kind = PortalHomeCardKind::Callout;
+installerHint.text = "Connect the device to its final local network.";
+wifi.portalAddHomeCard(installerHint);
+~~~
+
+Information sections and cards are copied at registration. Do not place secrets, passwords, API tokens, or personally identifying values in them.
+
+## Save callbacks
+
+| Callback | Use |
+| --- | --- |
+| setPreSaveParamsCallback() | Observe a parameter-only save before the normal parameter callback. |
+| setSaveParamsCallback(args) | Read, validate, and persist application settings after a parameter save. |
+| setPreSaveConfigCallback() | Observe a combined Wi-Fi/config save before Wi-Fi connection processing. |
+| setSaveConfigCallback() | React after Wi-Fi settings changed and the connection succeeded, or when break-after-config is enabled. |
+| setConfigResetCallback() | Clear or reconcile application configuration when the portal resets Wi-Fi settings. |
+
+Do not use a Wi-Fi-success callback to persist unrelated product settings: parameters can be saved separately, and an application needs its own durable-data policy.
+
+The buildable [Custom Portal Content](../examples/CustomPortalContent/) example demonstrates parameters, information sections, and home cards. This guide supplies the missing persistence and validation boundary.

+# Portal UI and configuration
+
+WiFiManagerPortalConfig is the supported presentation API for the built-in provisioning portal. It changes product identity and semantic visual tokens; the portal-policy methods below control the visibility and behavior of existing built-in features. WiFiManager continues to own portal routes, forms, navigation, captive behavior, reset, and OTA views.
+
+Apply presentation before autoConnect(), startConfigPortal(), or startWebPortal(). Configure portal policy during boot as well so each portal session begins consistently. Portal text and SVG assets are non-owning, so their RAM or PROGMEM data must have static firmware lifetime. WiFiManager locks presentation while a portal is active so asynchronous responses cannot observe partial configuration; setPortalConfig() returns false if it cannot accept the configuration.
+
+## Portal views
+
+These ESP32 captures use the same real-board portal test harness described in
+[Testing](TESTING.md). The nearby networks shown are the networks visible to
+the capture device when the portal scans.

+The complete buildable example is [Branded Portal](../examples/BrandedPortal/BrandedPortal.ino). The compile fixture exercises this API on ESP8266 and the maintained ESP32 3.3.11 baseline.
+
+## Presentation reference
+
+Leave a text or colour value empty, or a radius at 0, to retain the built-in stylesheet value.
+
+| Field | Used by |
+| --- | --- |
+| title | Document title and concise setup-page heading |
+| identityText | Company or product name in the header above navigation |
+| tagline | Short product context in the header above navigation |
+| logo.svg, logoAltText | Optional trusted inline SVG and its accessible label |
+| pageBackground, surface, text, mutedText, border | Portal surfaces and text |
+| accent, accentHover, accentText | Primary links and actions |
+| success, danger, dangerHover | Status and destructive actions |
+| cornerRadiusPx, smallCornerRadiusPx | Card and compact-control corners, limited to 64 px |
+
+Theme values accept simple named CSS values and are emitted once into a small
+portal theme block. Raw CSS and JavaScript are not supported. An SVG is a
+trusted compiled firmware asset, never form, MQTT, or network input.
+
+## Portal policy
+
+Use the portal-prefixed methods to choose which built-in pages and actions a
+product presents. Configure them during boot, before the portal starts, so a
+session begins with the intended behavior.
+
+~~~cpp
+// An installer portal that does not expose destructive reset or OTA actions.
+wifi.portalSetPageUpdateVisible(false);
+wifi.portalSetActionEraseVisible(false);
+wifi.portalSetActionRestartVisible(false);
+
+// Keep application settings on their own Setup page.
+wifi.portalSetLayoutParamsLocation(PortalParamsLocation::SetupPage);
+
+// Do not show saved passwords or static-IP fields unless the product needs them.
+wifi.portalSetFieldPasswordPlaceholderMode(PortalPasswordPlaceholderMode::Hidden);
+wifi.portalSetFieldStaticIpVisibility(PortalFieldVisibility::Hidden);
+wifi.portalSetFieldStaticDnsVisibility(PortalFieldVisibility::Hidden);
+~~~
+
+| Group | Methods | Use |
+| --- | --- | --- |
+| Pages | portalSetPageInfoVisible(), portalSetPageUpdateVisible(), portalSetPageSetupVisible() | Show only product-appropriate built-in pages. |
+| Actions | portalSetActionEraseVisible(), portalSetActionRestartVisible(), portalSetActionExitVisible(), portalSetActionCloseCaptiveVisible(), portalSetActionBackVisible() | Control existing action affordances; hiding an action is not a security boundary. |
+| Layout | portalSetLayoutParamsLocation() | Put registered parameters on the Wi-Fi page or separate Setup page. |
+| Connection/portal behavior | portalSetBehaviorCaptivePortalEnabled(), portalSetBehaviorConnectOnSave(), portalSetBehaviorExitAllowed(), portalSetBehaviorConnectTimeoutSeconds(), portalSetBehaviorPortalTimeoutSeconds(), portalSetBehaviorAutoReconnect(), portalSetBehaviorApClientCheck(), portalSetBehaviorWebClientCheck() | Set built-in portal behavior. |
+| Fields | portalSetFieldPasswordPlaceholderMode(), portalSetFieldStaticIpVisibility(), portalSetFieldStaticDnsVisibility() | Limit password disclosure and network-field visibility. |
+
+The older setConfigPortalTimeout(), setSaveConnect(), setShowStaticFields(), and related methods remain available. Prefer a single vocabulary within a product; the portal-prefixed methods make the policy visible in the portal's structured model.
+
+## Structured content
+
+Use portalAddParameter() for editable product settings, portalAddInfoSection() for labelled read-only values, and portalAddHomeCard() for overview text or key/value cards. Parameters remain application-owned; information sections and cards are copied when registered.
+
+See [Portal content](PORTAL_CONTENT.md) for the full persistence, validation, callback, and lifetime rules. The buildable [Custom Portal Content](../examples/CustomPortalContent/) example shows all three content types.
+
+## What stays built in
+
+Branding, policy, and structured content configure the supplied portal. The
+portal's HTML shell, routes, navigation, stylesheet, and scripts stay owned by
+WiFiManager. There is no custom shell, route replacement, navigation injection,
+raw stylesheet, or script hook.
+
+For a product-specific web application, start that application's own server
+after WiFiManager has completed provisioning. If the supplied portal needs a
+reusable capability, add one focused public WiFiManager C++ API and test it on
+ESP8266 and ESP32.

+# Provisioning lifecycle
+
+Choose a connection flow that matches the device's operating policy, then call process() regularly for as long as WiFiManager is active. It is a cooperative service call, not a hard real-time guarantee: target Wi-Fi or DNS work can occasionally take longer than a typical loop iteration. The consuming firmware owns its product-service lifecycle and restart decision.
+
+## Choose a flow
+
+| Need | Preferred API | What it does |
+| --- | --- | --- |
+| One saved station network, with portal fallback | autoConnect() | Tries saved credentials and starts the configuration portal when the attempt cannot connect. |
+| Primary plus fallback network with application-owned storage | setStationProfileStore() + startStationConnection() | Loads, selects, retries, and recovers a fixed two-profile station set. |
+| Verify a received profile before retaining it | startStationCandidate() | Attempts a primary/fallback candidate in memory and saves it only after success. |
+| Start setup under application control | startConfigPortal() | Starts an AP and captive configuration portal immediately. |
+| Show the portal while station Wi-Fi is already available | startWebPortal() | Starts the portal web service without starting a configuration AP. |
+
+The first two are the normal deployed-device flows. StartConfigPortal() and startWebPortal() are supported control APIs, but should be used only when the application has a clear policy for entering and leaving them.
+
+## Basic recovery flow
+
+~~~cpp
+#include <Arduino.h>
+#include <WiFiManager.h>
+
+WiFiManager wifi;
+
+void setup() {
+    Serial.begin(115200);
+    wifi.setConfigPortalTimeout(180);
+
+    if (wifi.autoConnect("Device Setup", "change-me")) {
+        startNormalApplication();
+    } else {
+        Serial.println("Wi-Fi setup portal is active");
+    }
+}
+
+void loop() {
+    wifi.process();
+
+    if (wifi.didConfigPortalConnectSucceed()) {
+        // The application decides whether to start services or reboot.
+        startNormalApplication();
+    }
+}
+~~~
+
+autoConnect() returns true when WiFiManager connected during that call. It returns false when it could not connect and has entered the portal path; false is not, by itself, an instruction to restart. Call process() every loop iteration while setup may be needed.
+
+A portal timeout is in seconds. setConfigPortalTimeout(0), the default, leaves the portal open. A field-installed product may deliberately use a longer bounded window, such as 15 minutes, so an installer has time to complete setup without leaving an unattended portal indefinitely.
+
+## Portal connection outcome
+
+For a portal save-and-connect attempt, use these getters instead of inferring state from the rendered page:
+
+| Getter | Meaning |
+| --- | --- |
+| getConfigPortalActive() | The configuration portal is currently running. |
+| hasEnteredConfigPortal() | The portal has been entered at least once this runtime session. |
+| isConfigPortalConnectPending() | A portal-submitted station connection is queued or waiting. |
+| didConfigPortalConnectSucceed() / didConfigPortalConnectFail() | Result of the last portal-submitted connection attempt. |
+| getConfigPortalConnectStatus() / getConfigPortalConnectMessage() | Platform Wi-Fi status and a human-readable result. |
+
+The local portal UI obtains the same state through its documented local API. Do not parse portal HTML to determine connection state.
+
+## Timing and policy
+
+Set these before the flow starts:
+
+| API | Use |
+| --- | --- |
+| setConfigPortalTimeout(seconds) | Limits a captive configuration session; setTimeout() is its deprecated alias. |
+| setConnectTimeout(seconds) and setConnectRetries(count) | Bounds legacy automatic connection attempts. |
+| setSaveConnectTimeout(seconds) | Bounds a portal save-and-connect attempt. |
+| setSaveConnect(enabled) | Controls whether a normal portal save attempts a station connection. |
+| setBreakAfterConfig(enabled) | Exits after a configuration submission even if the connection was unsuccessful. |
+| setEnableConfigPortal(enabled) / setDisableConfigPortal(enabled) | Controls autoConnect() portal fallback and its post-save shutdown behavior. |
+| setAPClientCheck(enabled) / setWebPortalClientCheck(enabled) | Controls whether AP/web-client activity affects the portal timeout. |
+
+The portal-prefixed behavior methods provide the same configuration through the structured portal contract; prefer one vocabulary consistently in a product.
+
+## Port ownership and clean handoff
+
+Before beginning a portal on port 80, stop any application server that already owns that port. After a portal connection succeeds, wait for the application's own readiness requirements before starting its server again. A successful station connection does not automatically make an application-level service ready.

+# Station profiles
+
+WiFiManager adds an opt-in station-profile controller for applications that need a primary Wi-Fi network and one fallback. It is independent of the legacy autoConnect() flow: existing WiFiManager consumers do not need to change.
+
+Profile mode is enabled only when the application supplies a WiFiManagerStationProfileStore. The store may be an in-memory implementation for a temporary session, but durable deployments should provide persistent storage.
+
+## Lifecycle
+
+A profile set has exactly two fixed slots:
+
+- **Primary** (slot 0) is required whenever the controller is enabled.
+- **Fallback** (slot 1) is optional.
+- The last successful slot is tried first on the next connection cycle, then the remaining enabled slot.
+
+The controller never treats the ESP SDK's saved single network as an additional source of truth. It begins one bounded connection attempt at a time, moves to the fallback after failure, and retries both profiles after a temporary loss of a previously working connection. If a new device has no valid profiles, it opens the normal configuration portal.
+
+A candidate submitted by the portal or another application subsystem is only committed after it connects and receives a usable IP address. A failed candidate leaves the last saved profile set intact.
+
+## Direct WiFiManager use
+
+Implement a small store appropriate to the application. The manager neither allocates nor owns it. This complete in-memory version makes the ownership and return contract visible; use the buildable EEPROM example when the profiles must survive a restart:
+
+```cpp
+class MemoryProfileStore final : public WiFiManagerStationProfileStore {
+public:
+    bool load(WiFiManagerStationProfiles& profiles) override {
+        if (!hasProfiles_) return false;  // No saved primary profile: open the portal.
+        profiles = profiles_;
+        return true;
+    }
+
+    bool save(const WiFiManagerStationProfiles& profiles) override {
+        profiles_ = profiles;
+        hasProfiles_ = true;
+        return true;  // A durable store must return false when its write fails.
+    }
+
+    bool clear() override {
+        profiles_ = {};
+        hasProfiles_ = false;
+        return true;
+    }
+
+private:
+    WiFiManagerStationProfiles profiles_{};
+    bool hasProfiles_ = false;
+};
+
+WiFiManager wifi;
+MemoryProfileStore profiles;  // Must outlive WiFiManager's asynchronous connection work.
+
+void setup() {
+    wifi.setStationProfileStore(&profiles);
+    wifi.setStationRecoveryInterval(30000);
+    wifi.startStationConnection("Example Setup", "setup-password");
+}
+
+void loop() {
+    wifi.process();  // Advances profile retries and serves the fallback portal.
+}
+```
+
+This memory-only store intentionally loses profiles on restart. The store must return a complete `WiFiManagerStationProfiles` value. Each enabled profile has a NUL-terminated SSID of at most 32 characters and an optional NUL-terminated password of at most 64 characters. Keep slot 0 enabled; set `hasPassword = false` for an open network.
+
+When load() returns false, WiFiManager treats the profile set as unavailable and opens the normal configuration portal. When save() or clear() returns false, getStationStatus().storageSaveFailed is set and the status message explains the failure.
+
+## Verified candidate flow
+
+Use startStationCandidate(candidate) when another application subsystem supplies a complete primary/fallback proposal:
+
+~~~cpp
+wifi.setStationProfileStore(&profiles);
+
+if (!wifi.startStationCandidate(candidate, "Example Setup", "setup-password")) {
+    reportInvalidProfileCandidate();
+}
+~~~
+
+WiFiManager tries the candidate in memory, then calls the attached store only after the station connects and has a usable IP address. Inspect getStationStatus() after WM_EVENT_STATION_PROFILE_CONNECTED: lastConnectionWasCandidate tells the application that this was a candidate, and storageSaveFailed distinguishes a usable but non-durable connection.
+
+Use saveStationProfiles(profiles) only when deliberately saving without a connection check. clearStationProfiles() asks the supplied store to clear profiles and disconnects the station only after that clear succeeds.
+
+The [Primary and fallback Wi-Fi recipe](recipes/PRIMARY_AND_FALLBACK_WIFI.md) shows why candidate verification protects known-good data.
+
+## Portal contract
+
+In profile mode, the existing Wi-Fi page becomes a two-profile form. It remains driven by the same local portal endpoints:
+
+- GET /api/wifi/meta returns profiles, activeSlot, and controller state without passwords.
+- POST /api/wifi/save accepts s0/p0 for primary and s1/p1 for fallback. A blank submitted password preserves an existing password; send clear0 or clear1 for an intentional open network.
+- A normal save verifies the candidate by connecting. The built-in portal polls GET /api/wifi/connect-status for its result.
+- stationAction=save stores the submitted profiles for a later connection attempt.
+
+The portal requires a non-empty primary SSID. Its local protocol never returns a password. See [Portal API](PORTAL_API.md) for the shared connection-status response.
+
+## Recovery and troubleshooting
+
+| Symptom | Inspect | Meaning |
+| --- | --- | --- |
+| Portal starts immediately | getStationStatus().configuredProfiles and message | Store had no valid primary profile, so WiFiManager did not fall back to SDK-owned credentials. |
+| Repeated network recovery | state, attemptedSlot, activeSlot, and WM_EVENT_STATION_BACKOFF | The controller is trying configured profiles with the recovery interval. |
+| Candidate is connected but lost after reboot | lastConnectionWasCandidate and storageSaveFailed | The candidate connected, but the application store did not retain it. |
+| Portal form rejects a save | Local API response/message | Primary profile was missing or SSID/password bounds were invalid. |
+| Profiles do not clear | storageSaveFailed and message | The application store rejected clear(); fix its storage error before assuming Wi-Fi was removed. |
+
+The buildable [Station Profiles](../examples/StationProfiles/) example contains a compact EEPROM-backed store for both supported ESP targets.

+# Testing
+
+WiFiManager separates repeatable board-free builds from opt-in tests that flash
+a real board or join a captive portal. The normal commands never need a board,
+local Wi-Fi credentials, browser binary, or sibling checkout.
+
+| Physical test harness | Transport | Host adapter | Secret source | Required proof |
+| --- | --- | --- | --- | --- |
+| Portal lifecycle suite | Serial flash + captive-portal HTTP/browser | Named secondary adapter | safe fixture AP password | Unity/lifecycle checks and portal UI/API coverage |
+| Portal HTTP OTA | WiFiManager multipart `POST /u` | Named secondary adapter | safe fixture AP password | rendered upload succeeds, portal restarts automatically, and fixture marker changes A → B twice |
+
+The selected secondary adapter is intentionally never used for normal LAN
+testing. It is `never-default`, so the host's ordinary route remains intact.
+
+## Board-free fixture, consumer, and example builds
+
+The Unity compile check builds WiFiManager's own fixture without a board. The
+consumer check builds a project that declares only WiFiManager, proving that a
+normal PlatformIO dependency resolution can compile DFTE, ESPAsyncWebServer,
+and the correct ESP8266 or ESP32 TCP dependency. Normal commands reuse the
+persistent PlatformIO cache; they do not delete, reinstall, or separately
+assert the package graph.
+
+```bash
+./scripts/test.sh compile --platform esp8266
+./scripts/test.sh compile --platform esp32
+./scripts/test.sh unity --platform esp8266
+./scripts/test.sh unity --platform esp32
+./scripts/test.sh examples --platform esp8266
+./scripts/test.sh examples --platform esp32
+./scripts/test.sh ota-fixtures --platform esp8266
+./scripts/test.sh ota-fixtures --platform esp32
+```
+
+CI runs these board-free checks for pull requests and pushes to the maintained
+branch. `esp32` uses Arduino-ESP32 3.3.11 and compiles the guided examples.
+The OTA fixture builds compile both immutable A
+and B images against their tracked OTA partition layout. CI rejects equal A/B
+artifacts, an ESP32 image larger than either 0x1F0000-byte app slot, or a
+partition-table edit that breaks the required two-slot/no-filesystem layout. These checks
+intentionally do not require attached hardware, a local network, or Docker.
+
+Direct PlatformIO test-harness commands default to two compiler jobs. Set
+`PLATFORMIO_RUN_JOBS=3` only for an explicit local run on an otherwise idle
+host.
+
+Physical portal commands lock the shared `192.168.4.0/24` portal network, the
+selected secondary adapter, and the named serial device. These non-secret
+resource locks are shared with DeviceFramework's portal harness, so a collision
+fails before either runner changes a board or adapter while unrelated station
+tests can use their own resources.
+
+## Local hardware lifecycle tests
+
+The Unity suite runs portal-only firmware with no Wi-Fi credentials, MQTT,
+product application framework, or local profile. It verifies portal start/stop
+recovery, scan-cache release, and a real asynchronous Wi-Fi scan.
+
+Use a stable serial-by-id path rather than a changing `/dev/ttyUSB` number:
+
+```bash
+pio device list
+./scripts/test.sh hardware --platform esp8266 --port /dev/serial/by-id/usb-...
+./scripts/test.sh hardware --platform esp32 --port /dev/serial/by-id/usb-...
+```
+
+The runner flashes the selected board, captures normal-boot serial output with
+the repository Bash helper, requires Unity's `Tests 0 Failures` and `OK`
+summary, and prints lifecycle metrics. Hardware work shares a lock with the
+portal test harness and DeviceFramework's hardware runners on the same host, so
+two first-party invocations cannot flash or use the same board at once.
+
+## Docker portal test harness
+
+`test/portal-harness` is deliberately tiny portal-only firmware, not an example
+or consuming application. `tools/portal-hardware` flashes it to one explicitly
+selected board, joins its AP through one explicitly selected **secondary**
+Wi-Fi adapter, then runs its HTTP and browser test harness in a pinned Playwright
+Docker image. Docker uses host networking only to reach the already-routed
+portal; it never runs NetworkManager or changes host adapters.
+
+The runner resolves PlatformIO from `WIFIMANAGER_PIO_EXECUTABLE`, then `PATH`,
+then PlatformIO's standard `~/.platformio/penv/bin/pio` installation. That
+makes the same command work from a non-interactive SSH shell without modifying
+the user's `PATH`.
+
+### NetworkManager authorization
+
+The portal adapter is a host-side resource, separate from fixture credentials.
+The runner never reads a sudo password from `test/.env`, an environment file,
+or source control. `doctor` reports whether the current session can use
+NetworkManager directly or will need scoped sudo. In a graphical desktop,
+Polkit normally authorizes the selected adapter directly. In an SSH or other
+headless session with no Polkit agent, the runner visibly validates `sudo -v`
+before it erases or flashes the board, then uses `sudo -n nmcli` only to scan,
+disconnect, join, and remove its generated connection on the named secondary
+adapter.
+
+The normal setting is `WM_NMCLI_AUTH=auto`. Use `WM_NMCLI_AUTH=sudo` to choose
+the same scoped path deliberately, or `WM_NMCLI_AUTH=direct` only when a
+working Polkit policy already grants the required actions. Do not run the whole
+runner under `sudo`: its state files and browser artifacts intentionally remain
+owned by the invoking developer. If the sudo ticket expires during a long run,
+the runner stops with an actionable message rather than silently treating an
+unauthorized rescan as a missing portal SSID. `down` uses the same scoped path
+to remove a retained connection.
+
+```bash
+./tools/portal-hardware doctor --client-interface wlx74da385d4165
+./tools/portal-hardware run \
+  --platform esp8266 \
+  --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165
+```
+
+The command refuses the host default-route adapter. If the chosen secondary
+adapter is already connected, require an explicit acknowledgement before it is
+replaced:
+
+```bash
+./tools/portal-hardware run ... --take-over-client-adapter
+```
+
+The fixture opens a 15-minute portal session and includes thirteen harmless
+custom parameters. It verifies root/bootstrap/info/status API responses,
+concurrent low-priority requests, every custom field and value across repeated
+API fetches, timeout reset, an actual async scan, a missing-route response, and
+desktop/mobile portal rendering with no browser page errors. It also round-trips
+a value containing apostrophes, quotes, backslashes, angle brackets, and an
+ampersand through the rendered form and parameter-save API. Screenshots, traces
+on failure, JSON results, and the HTML report are saved under the printed XDG
+state-directory artifact path.
+
+On ESP8266, an AP+STA scan can briefly move the radio off the AP channel. The
+client may reconnect during that interval; the test harness deliberately retries
+that transport interruption and still requires a reachable portal with a
+complete, valid scan result.
+
+The normal browser test harness catches the common regression case. When changing
+parameter rendering, run the opt-in ESP8266 soak as well. It performs twelve
+full browser renders and API fetches while the AP is active, asserting all
+thirteen fields and their exact values on every pass. This targets the
+memory-sensitive rendering failure reported upstream in issue #1787 without
+making every ordinary hardware run unnecessarily long:
+
+```bash
+./tools/portal-hardware run \
+  --platform esp8266 \
+  --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165 \
+  --custom-parameter-stress
+```
+
+For interactive diagnosis, leave the temporary client connection up and remove
+only that managed connection when finished:
+
+```bash
+./tools/portal-hardware up --platform esp32 --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165
+./tools/portal-hardware down
+```
+
+An optional station handoff test is deliberately separate because it connects
+the fixture to a real LAN. Copy the ignored template below, add local
+credentials, and pass it explicitly. The runner parses only `WIFI_SSID` and
+`WIFI_PASSWORD` into a generated mode-600 two-key file, mounts that file
+read-only into the test container, and removes it after the browser run; it
+never mounts the complete local environment file or logs either value. Because
+browser traces can retain request bodies, this opt-in mode disables Playwright
+screenshots, video, and tracing, including explicit diagnostic screenshots. It
+cannot be combined with README-media capture. Docker builds from the tracked
+`tests/portal-harness` directory only, so neither the source environment file
+nor the generated two-key file enters its build context. Keep its private output
+directory private and review any remaining report before sharing it.
+
+After either a passing or failing station-handoff attempt, the runner
+serial-flashes the portal-only fixture once more. Its `setup()` clears saved
+station settings, so the selected test board returns to the clean no-station
+portal state and does not retain the developer's Wi-Fi credentials. A failed
+restore or a failure to see the cleaned fixture AP return makes the command
+fail. `--keep` affects only the runner's temporary
+secondary-adapter connection; it does not retain station credentials on the
+board.
+
+A retained session is deliberately never overwritten. Before touching
+NetworkManager, the runner atomically records its uniquely generated connection
+name; after creation it atomically replaces that pending record with the exact
+UUID. Ordinary failures and interrupts remove that connection immediately, and
+`down` accepts either record after an uncatchable host termination or an
+intentional `up`/`--keep` session. It never removes another NetworkManager
+connection.
+
+```bash
+cp test/portal-station.env.example test/portal-station.env
+./tools/portal-hardware run ... --station-env test/portal-station.env
+```
+
+## Refresh README media
+
+README media is an explicit ESP32-only capture, not part of normal testing or
+CI. It uses the same real-board portal test harness above, but records a short
+browser tour and stores all candidate files under the ignored
+`artifacts/readme-media/` directory by default:
+
+```bash
+./tools/portal-hardware run \
+  --platform esp32 \
+  --port /dev/serial/by-id/usb-... \
+  --client-interface USB_WIFI_ADAPTER \
+  --capture-readme-media
+```
+
+Review the printed artifact directory. To keep a run somewhere more convenient,
+pass `--output DIRECTORY`. After review, promote only the approved PNG/GIF
+files into tracked documentation assets:
+
+```bash
+./tools/promote-readme-media \
+  --from artifacts/readme-media/TIMESTAMP-esp32 \
+  --replace
+./scripts/check-docs.sh
+```
+
+The Docker renderer validates the GIF duration. The promotion tool requires the
+successful ESP32 media manifest, checks file types and size limits, and never
+copies raw video, browser reports, traces, or arbitrary artifact files. The
+renderer preserves the real recording but deliberately presents it at 1.25×
+duration and 6 fps so the
+README tour is readable; it does not change normal browser-test-harness timing.
+ESP8266 remains covered by the normal hardware and browser test harness but does
+not produce duplicate README media.
+
+## Portal HTTP OTA A/B test harness
+
+`portal-hardware ota` is a separate opt-in physical test for WiFiManager's
+built-in HTTP update path. It exercises the rendered firmware-update page and
+its real multipart `POST /u` request; it is not an ArduinoOTA/UDP test.
+
+```bash
+./tools/portal-hardware ota \
+  --platform esp8266 \
+  --port /dev/serial/by-id/usb-... \
+  --client-interface wlx74da385d4165
+```
+
+The selected `--client-interface` has exactly the same safety rules as the
+normal portal test harness: it must be the explicitly named secondary adapter and
+cannot be the host default-route interface. The test never attaches that
+adapter to a normal station network. The fixture AP uses the safe local
+`default1` WPA password; this is an AP-access test, not a claim that `/u` has
+HTTP route authentication.
+
+The test harness performs the following complete run:
+
+1. Builds immutable A and B fixture images from one platform environment. A
+   generated harness-only header in an ignored, per-run private directory is
+   the only changed input, so their marker is compiled into the binary rather
+   than saved in WiFiManager settings or EEPROM.
+2. Checks both ESP32 images against the explicit matching `app0`/`app1` slots;
+   ESP8266 validates B after A has booted against the exact aligned capacity
+   passed to `Update.begin()`.
+3. Erases the explicitly selected test board's flash, then flashes A over
+   serial and starts its captive portal.
+4. Joins that portal only through the named secondary adapter and requires the
+   A marker at `/api/test/firmware-marker`.
+5. Mounts B read-only into the Playwright container, chooses it in the real
+   `#wm-ota-file` browser input, and submits the rendered form.
+6. Requires the real `POST /u` success response, an automatic portal outage,
+   automatic restart, and two independent B-marker responses.
+
+The OTA command additionally requires Python with PySerial (the
+`python3-serial` package on Debian/Ubuntu) and retains a passive,
+no-reset `serial-ota.log` beside the browser artifacts. It attaches immediately
+after serial-flashing A releases the port—before portal association and the A
+marker check—and remains attached through the two B checks. A passing run
+requires a healthy recorder, but its contents are diagnostic evidence rather
+than a pass/fail comparison against product log strings. This preserves
+firmware-side portal-start and DHCP evidence without manufacturing a reset.
+OTA-only fixture images wait five seconds after their upload reset so
+the passive recorder can attach before A/B boot evidence is emitted; ordinary
+portal test-harness startup remains fast.
+
+The fixture marker endpoint exists only in `test/portal-harness`; it is not a
+WiFiManager library route or a product-firmware pattern. The test does not
+issue a manual reset. A board which boots B only after intervention is a
+failure, even if B later appears.
+
+Both fixture images are built with explicit OTA-capable layouts:
+
+| Platform | Fixture layout | Capacity check |
+| --- | --- | --- |
+| ESP8266 | `eagle.flash.4m1m.ld` | A's live `ESP.getFreeSketchSpace()` response |
+| ESP32 | two `0x1F0000` A/B app slots, no filesystem | tracked CSV `app1` size |
+
+These are 4 MB fixture layouts (`d1_mini` for ESP8266 and `esp32dev` for
+ESP32). Do not run this command against a board with another flash size unless
+its matching explicit A/B layout and capacity checks have been added first.
+
+The final board state is firmware B in the portal-only fixture: it clears
+saved station settings on every boot and leaves no developer Wi-Fi credential
+on the device. By default the temporary NetworkManager connection is removed
+when the test exits. Pass `--keep` only for interactive diagnosis, then run
+`./tools/portal-hardware down` to remove that named temporary connection.

+# Field installer provisioning
+
+A field-installed controller or sensor often needs more time for setup than a desk-bound demo, but should not host an unattended configuration portal forever. Existing consuming device sketches solve this by choosing a deliberate 15-minute configuration window and exposing clear local feedback while setup is active.
+
+## Flow
+
+1. Boot with the product's normal configuration.
+2. Try the stored primary/fallback profile set.
+3. If Wi-Fi is unavailable, start the local setup AP and portal.
+4. Keep the portal available for the installation window.
+5. On a successful connection, let the application start services or reboot according to its own policy.
+6. On timeout, return to the product's recovery policy rather than assuming the installer finished.
+
+~~~cpp
+constexpr unsigned long kInstallerWindowSeconds = 15 * 60;
+MyProfileStore profileStore;
+
+void setup() {
+    configureProductPortal();
+    wifi.setStationProfileStore(&profileStore);
+    wifi.setStationRecoveryInterval(30000);
+    wifi.setConfigPortalTimeout(kInstallerWindowSeconds);
+
+    wifi.setAPCallback([](WiFiManager*) {
+        setIndicator(IndicatorState::Setup);
+        showInstallerInstructions();
+    });
+
+    wifi.setConfigPortalTimeoutCallback([] {
+        setIndicator(IndicatorState::Offline);
+        recordSetupTimeout();
+    });
+
+    wifi.startStationConnection(deviceSetupName(), deviceSetupPassword());
+}
+
+void loop() {
+    wifi.process();
+    // Do not start or recreate an application server while the portal owns its port.
+}
+~~~
+
+The timeout is a product decision. A short interval is appropriate for a user-facing appliance; a longer maintenance window may be justified for a device installed in a cabinet or plant room. Set 0 only when an always-open setup portal is an explicit operational choice.
+
+## What to show an installer
+
+Keep feedback independent of a browser redirect:
+
+- the setup SSID and any required password;
+- the device's portal address and non-default port, if configured;
+- a distinct setup indicator while the portal is active;
+- a distinct failure/offline indication after timeout;
+- confirmation only after Wi-Fi has actually connected.
+
+Use getConfigPortalActive(), didConfigPortalConnectSucceed(), and getConfigPortalConnectMessage() for this state. See [Observability](../OBSERVABILITY.md).
+
+## Product boundary
+
+WiFiManager supplies the local portal and timer. The product decides what happens after timeout: keep retrying profiles, sleep, wait for a physical action, or operate in an offline mode. If startStationConnection() returns false because no usable stored profile exists, the portal may be the intended next state rather than a reason to reboot immediately.
+
+For a product that deliberately uses one platform-saved network rather than primary/fallback profiles, the smaller legacy equivalent is wifi.autoConnect(deviceSetupName(), deviceSetupPassword()). It has the same local portal fallback, but no application-owned profile store, candidate verification, or fallback network.

+# Local web-service handoff
+
+A product may already host its own local HTTP service when a later connection failure opens WiFiManager's provisioning portal. Because WiFiManager owns its portal server port while active, the product must release that port before WiFiManager registers its portal routes.
+
+A real consuming framework does this from the AP callback: it shuts down its normal web service after the setup AP has started but before WiFiManager registers portal routes.
+
+## Automatic recovery handoff
+
+~~~cpp
+MyProfileStore profileStore;
+
+void setup() {
+    wifi.setStationProfileStore(&profileStore);
+    wifi.setStationRecoveryInterval(30000);
+
+    wifi.setAPCallback([](WiFiManager*) {
+        stopApplicationWebServer();  // Releases port 80 for WiFiManager.
+        setIndicator(IndicatorState::Setup);
+    });
+
+    wifi.startStationConnection("Device Setup", "setup-password");
+}
+~~~
+
+The AP callback runs after AP mode begins and before the portal routes are registered. It is the appropriate hook for automatic portal fallback. This profile-controller form matches the consuming firmware's recovery flow. If a product deliberately uses one platform-saved network instead, replace startStationConnection(...) with wifi.autoConnect(...); the same AP callback ordering applies. If the application explicitly starts setup itself, release its server before calling startConfigPortal().
+
+## After a successful connection
+
+The portal's successful Wi-Fi connection means the station has an address. It does not guarantee that the product's own web application, MQTT connection, or sensors are ready. The product should:
+
+1. observe didConfigPortalConnectSucceed() or the matching event;
+2. persist any application settings required for normal operation;
+3. choose whether to restart or recreate its own server;
+4. only advertise the product service when it is ready.
+
+If the product uses a non-default WiFiManager HTTP port, it can avoid a port conflict but must treat the portal URL and its station-connect handoff URL as that non-default port.
+

+# Primary and fallback Wi-Fi
+
+Some deployed devices receive a primary Wi-Fi network and an optional fallback from a local provisioning source. The consuming framework uses WiFiManager's fixed two-profile controller so it can verify a candidate connection before replacing durable known-good profiles.
+
+## Flow
+
+1. The application obtains a complete candidate profile set.
+2. It gives the candidate to startStationCandidate().
+3. WiFiManager attempts the primary profile and then fallback when needed.
+4. On a usable station connection, WiFiManager saves the candidate through the application-owned store.
+5. If connection or storage fails, the application can report the result without silently replacing known-good data.
+
+~~~cpp
+WiFiManagerStationProfiles candidate = makeDeploymentProfiles();
+
+wifi.setStationProfileStore(&profileStore);
+wifi.setStationRecoveryInterval(30000);
+
+if (!wifi.startStationCandidate(candidate, "Device Setup", "setup-password")) {
+    reportRejectedProfileSet();
+}
+~~~
+
+A candidate needs a non-empty enabled primary slot. The fallback slot is optional. WiFiManager never exposes profile passwords through the portal metadata API.
+
+## Treat persistence result as part of success
+
+A candidate can connect successfully while the profile store fails to write. Read getStationStatus() when WM_EVENT_STATION_PROFILE_CONNECTED arrives:
+
+~~~cpp
+wifi.setEventCallback([](WiFiManager::wm_event_t event) {
+    if (event != WiFiManager::WM_EVENT_STATION_PROFILE_CONNECTED) {
+        return;
+    }
+
+    const auto& status = wifi.getStationStatus();
+    if (status.lastConnectionWasCandidate && status.storageSaveFailed) {
+        reportConnectedButNotRetained();
+    }
+});
+~~~
+
+This distinction matters in unattended devices: the device works now, but may fail to reconnect after a restart.
+
+## Bootstrap and reconcile are application decisions
+
+WiFiManager verifies and selects station profiles. It does not define whether a product should accept a supplied profile only on first boot, replace values after an explicit revision, or merge settings from another system. Keep that policy in the application, alongside its durable configuration and schema migration.
+
+See [Station profiles](../STATION_PROFILES.md) for store requirements, portal fields, and the complete controller lifecycle.

+# Product settings and Wi-Fi
+
+A connected device often needs more than an SSID and password: a device name, broker host, endpoint, operating mode, or installer-selected option. The actual consuming framework pattern is to load those settings before WiFiManager begins, expose them as portal parameters, and persist them through the application's own storage layer.
+
+## Flow
+
+1. Load the application's durable settings and run its schema migration.
+2. Build WiFiManagerParameter objects from the loaded values.
+3. Register those parameters before a portal can start.
+4. Register the save-parameters callback.
+5. Validate and persist submitted application values through the application's storage layer.
+6. Separately observe a successful Wi-Fi configuration/save if product services need a connected station first.
+
+~~~cpp
+constexpr int kBrokerHostLength = 64;
+WiFiManagerParameter brokerHost(
+    "broker_host", "MQTT broker", "", kBrokerHostLength);
+
+void configurePortalFromSettings() {
+    brokerHost.setValue(settings.mqttHost.c_str(), kBrokerHostLength);
+    wifi.portalAddParameter(&brokerHost);
+
+    wifi.setSaveParamsCallback([](WiFiManager::WiFiManagerRequestArgs) {
+        const String requestedHost = brokerHost.getValue();
+
+        if (!isValidHostname(requestedHost)) {
+            logRejectedSetting("broker_host");
+            return;
+        }
+
+        settings.mqttHost = requestedHost;
+        if (!saveApplicationSettings(settings)) {
+            reportConfigurationStorageFailure();
+        }
+    });
+}
+~~~
+
+WiFiManager does not own settings, schema migration, or the storage transaction. In particular, an application should keep known-good settings if validation or storage fails.
+
+## Keep the two persistence paths separate
+
+| Data | Owner | Save trigger |
+| --- | --- | --- |
+| Wi-Fi credentials in legacy mode | WiFiManager/platform Wi-Fi | Portal Wi-Fi save and connection flow |
+| Primary/fallback station profiles | Application-provided profile store | Profile controller after verified candidate connection, or explicit save |
+| Product settings | Application | setSaveParamsCallback() and application validation |
+| Product schema/revision | Application | Application boot/migration policy |
+
+A profile provisioning revision is not the same thing as an application schema version. The application owns both migration and the decision to apply a configuration update.
+
+## Form placement
+
+Use portalSetLayoutParamsLocation(PortalParamsLocation::WiFiPage) for one or two values that naturally belong in initial connectivity setup. Use SetupPage for product configuration that deserves a separate step. Put read-only status in PortalInfoSection or PortalHomeCard rather than turning it into a parameter.
+
+For lifetime and callback details, see [Portal content](../PORTAL_CONTENT.md).

+# Provisioning state feedback
+
+A physical device should give useful feedback without relying on a captive-browser redirect. Existing consuming firmware uses WiFiManager state to make setup, recovery, and connected states visible through an LED, display, or local log.
+
+## State model
+
+| Product state | WiFiManager signal | Typical feedback |
+| --- | --- | --- |
+| Normal connected operation | Station/profile controller connected, no configuration portal | Normal indicator and application services. |
+| Trying known networks | Profile status is attempting or switching | Short recovery indication; no claim that setup is active yet. |
+| Setup portal active | getConfigPortalActive() is true or WM_EVENT_PORTAL_STARTED | Installer-oriented setup indication and instructions. |
+| Portal submitted credentials | isConfigPortalConnectPending() is true | Progress indication. |
+| Portal connection succeeded | didConfigPortalConnectSucceed() or WM_EVENT_PORTAL_CONNECT_SUCCESS | Connected confirmation; application decides when services start. |
+| Portal connection failed | didConfigPortalConnectFail() or WM_EVENT_PORTAL_CONNECT_FAILED | Failure indication with retry/recovery policy. |
+| Candidate connected but not stored | Station event plus storageSaveFailed | Warning: active connection may not survive restart. |
+
+## Polling pattern
+
+~~~cpp
+void updateIndicator() {
+    if (wifi.getConfigPortalActive()) {
+        setIndicator(IndicatorState::Setup);
+    } else if (wifi.isConfigPortalConnectPending()) {
+        setIndicator(IndicatorState::Connecting);
+    } else if (wifi.didConfigPortalConnectFail()) {
+        setIndicator(IndicatorState::Offline);
+    } else {
+        setIndicator(IndicatorState::Normal);
+    }
+}
+~~~
+
+Call this from the application loop after wifi.process(). For profile mode, add getStationStatus() so the product can distinguish an active station recovery attempt from a portal session.
+
+## Event pattern
+
+Events reduce polling for transitions, but getters remain the authoritative state. Use setEventCallback() to record a transition or wake a product state machine, then read the relevant portal/profile status. Avoid performing long work in the callback; keep it suitable for the normal firmware loop.
+
+## Operator-facing messages
+
+Use getConfigPortalConnectMessage() and getWLStatusString() for concise local diagnostics. Never place Wi-Fi passwords, portal parameter values, or secrets in an operator display or remotely collected logs.
+
+See [Observability](../OBSERVABILITY.md) for the complete event list and [Field installer provisioning](FIELD_INSTALLER_PROVISIONING.md) for timeout policy.

+# Integration recipes
+
+These patterns come from real firmware that consumes this WiFiManager fork. They describe the boundary between a product application and WiFiManager; they are not additional framework APIs and do not require a cloud service or companion app.
+
+| Scenario | Start here when… |
+| --- | --- |
+| [Field installer provisioning](FIELD_INSTALLER_PROVISIONING.md) | A physical device needs a deliberately bounded setup window on site. |
+| [Product settings and Wi-Fi](PRODUCT_SETTINGS_AND_WIFI.md) | The portal collects Wi-Fi and application-owned settings together. |
+| [Primary and fallback Wi-Fi](PRIMARY_AND_FALLBACK_WIFI.md) | A deployment supplies a candidate primary/fallback network that must be verified before storage. |
+| [Local web-service handoff](LOCAL_WEB_SERVICE_HANDOFF.md) | The application already owns port 80 when recovery provisioning may begin. |
+| [Provisioning state feedback](PROVISIONING_STATE_FEEDBACK.md) | LEDs, a display, or logs need to distinguish setup, recovery, and connected states. |
+
+The normal [Basic Portal](../../examples/BasicPortal/) example remains the shortest way to try the legacy saved-network-or-portal flow. These recipes explain the product concerns that a standalone example should not pretend to solve.

+# Basic Portal
+
+This is the smallest useful WiFiManager application. It first tries the credentials the ESP platform already knows. If it cannot connect, it opens an access point named **WiFiManager Basic** with password **example-pass**.
+
+1. Build and flash the selected `esp8266` or `esp32` environment.
+2. Connect a phone or computer to **WiFiManager Basic**.
+3. Open `http://192.168.4.1/` if your captive-portal helper does not open it automatically.
+4. Select a network and save it. The board joins that network and the next reboot reconnects without opening the portal.
+
+The access-point password is only an example. Choose a unique, Wi-Fi-valid password for a real product.
+
+See the shared [example guide](../README.md), [getting started](../../docs/GETTING_STARTED.md), and [provisioning lifecycle](../../docs/PROVISIONING_LIFECYCLE.md).

+# Branded Portal
+
+This example uses the supported `WiFiManagerPortalConfig` presentation API to give the built-in portal a product name, company identity, tagline, inline SVG mark, and semantic colour tokens.
+
+Flash the `esp8266` or `esp32` environment, join **Temperature Monitor**, and open `http://192.168.4.1/`. The visual changes come from static firmware data; WiFiManager still owns the portal routes, forms, validation, and captive-network behaviour.
+
+Use only trusted compiled SVG data. Keep the backing strings static for the lifetime of the firmware, then call `setPortalConfig()` before opening a portal.
+
+See [Portal UI and configuration](../../docs/PORTAL_UI.md), [architecture boundaries](../../docs/ARCHITECTURE.md), and the shared [example guide](../README.md).

+# Custom Portal Content
+
+This example keeps WiFiManager’s portal navigation, validation, and captive behaviour, while adding three application-owned pieces of content:
+
+- an editable MQTT broker host field;
+- a compact device-information section;
+- a callout on the portal overview.
+
+It opens **WiFiManager Content** with password **example-pass** until it has working station credentials. Save the form, then inspect serial output to see the selected broker value.
+
+The parameter object is global because WiFiManager reads it for the lifetime of the portal. In a real application, copy the value into that application’s own validated persistent configuration inside the save callback.

+| [Basic Portal](BasicPortal/) | provision one board through the normal saved-network-or-portal flow |
+| [Custom Portal Content](CustomPortalContent/) | add application settings and useful status cards to the built-in portal |
+| [Branded Portal](BrandedPortal/) | change the portal’s identity, logo, and semantic visual theme |
+| [Station Profiles](StationProfiles/) | remember a primary Wi-Fi network and one fallback in application-owned EEPROM storage |
+
+The portal examples intentionally begin with no station credentials. On first boot, connect to the matching setup network and open `http://192.168.4.1/`.

+# Station Profiles
+
+This example gives WiFiManager a small application-owned EEPROM store. The portal accepts a required primary Wi-Fi network and an optional fallback, verifies a submitted network before saving it, then remembers the last successful choice across restarts.
+
+On a blank board, connect to **WiFiManager Profiles** with password **example-pass** and open `http://192.168.4.1/`. Enter a primary network and, if useful, one fallback. After a successful connection, restart the board to confirm that it tries the saved profiles before reopening the portal.
+
+`StoredProfiles` is intentionally simple so the ownership boundary is visible. A production application should add its own record versioning and integrity protection around the application’s complete configuration; WiFiManager only owns network-selection policy.
+
+See [Station profiles](../../docs/STATION_PROFILES.md), [primary and fallback Wi-Fi](../../docs/recipes/PRIMARY_AND_FALLBACK_WIFI.md), and the shared [example guide](../README.md).

+# Portal browser harness
+
+This test fixture starts only the WiFiManager captive portal. It intentionally has no station credentials, MQTT configuration, DeviceFramework dependency, or application logic.
+
+Use it through the repository runner so a secondary Wi-Fi adapter is explicitly selected and protected from becoming the host default route:
+
+```bash
+./tools/portal-hardware run \
+  --platform esp8266 \
+  --port /dev/serial/by-id/... \
+  --client-interface wlx...
+```
+
+The ESP8266 portal SSID is `WM Test Harness ESP8266`; the ESP32 SSID is `WM Test Harness ESP32`. Both use `default1` exclusively for local development tests.
+
+The runner cleans up only the temporary connection it creates on the named secondary interface. It refuses to run if that interface is the system default route.
+
+NetworkManager authority is a host prerequisite, not a fixture secret. A GUI
+Polkit session may authorize the adapter directly; a headless/SSH invocation
+validates sudo before flashing, then elevates only the generated portal
+connection actions. Leave the runner itself unprivileged so its private state
+and browser artifacts remain owned by the developer. See
+[`docs/TESTING.md`](../../docs/TESTING.md#networkmanager-authorization) for
+the `WM_NMCLI_AUTH` options.
+
+## A/B portal OTA fixture
+
+The physical portal HTTP OTA test harness uses one `*_ota` environment per
+platform. It writes a harness-only A/B identity header to an ignored, owner-only
+directory unique to that run before each build, so PlatformIO reuses dependency
+objects while the fixture-only `/api/test/firmware-marker` endpoint still proves
+the newly booted image. The test harness requires the real form's successful response, its automatic
+restart, and two fresh B-marker responses. Passive serial capture is retained
+for failure diagnosis, but a product log-message wording change cannot turn a
+successful A-to-B update into a failed test.
+
+```bash
+./tools/portal-hardware ota \
+  --platform esp32 \
+  --port /dev/serial/by-id/... \
+  --client-interface wlx...
+```
+
+ESP8266 explicitly uses `eagle.flash.4m1m.ld`. ESP32 uses the tracked two-slot
+`partitions/esp32_ota_4m_no_fs.csv` layout on the maintained Arduino-ESP32
+3.3.11 fixture lane. Both are 4 MB layouts. The runner builds and preserves A
+and B before it touches the board, validates the matching ESP32 slots (or the
+live ESP8266 updater capacity), then erases the explicitly selected test board
+before serial-flashing A. A successful run leaves B installed in the
+portal-only fixture. It requires Python PySerial and retains a passive,
+no-reset `serial-ota.log` in the private run artifact directory for both
+success and failure diagnosis.
