+# API Changes (Not Yet Reflected in `backend/openapi/openapi.json`)
+
+This document lists additive API changes currently implemented in the Go backend.
+
+## Summary
+
+Existing endpoints remain compatible.
+
+Added capabilities:
+
+1. Position board persistence for live/admin ordering.
+2. Stage session control (`start`/`end`) for event flow.
+3. Stage history retrieval.
+4. New state fields (`positionBoards`, `current_stage`, `last_stage`).
+
+## 1) Position Board Endpoint
+
+- Method: `PUT`
+- Path: `/api/admin/positions/:board`
+- Auth: admin bearer token (`Authorization: Bearer <token>`)
+
+### Supported `:board` values
+
+- `preliminary`
+- `final`
+- `prelim_tiebreak`
+- `final_tiebreak`
+
+### Request body
+
+```json
+{
+  "slots": [
+    { "playerId": 12, "groupKey": "A", "position": 1 },
+    { "playerId": 15, "groupKey": "A", "position": 2 },
+    { "playerId": 20, "groupKey": "B", "position": 1 }
+  ]
+}
+```
+
+Fields:
+
+- `playerId` (integer, required)
+- `groupKey` (string, required)
+- `position` (integer > 0, required)
+
+Notes:
+
+- The request replaces all saved slots for the target board.
+- For `preliminary`, `players.group_code` is synchronized from `groupKey`.
+- Special value `UNASSIGNED` maps to empty player group.
+
+### Response
+
+- `200 OK` with full updated admin state payload.
+
+## 2) Stage Session Control Endpoints
+
+### Start stage
+
+- Method: `POST`
+- Path: `/api/admin/stage/start`
+- Auth: admin bearer token
+
+Request body:
+
+```json
+{
+  "phase": "preliminary",
+  "group": "A",
+  "round": 2
+}
+```
+
+Rules:
+
+- `phase` must be one of:
+  - `preliminary`
+  - `prelim_tiebreak`
+  - `final`
+  - `final_tiebreak`
+- `group` validation depends on phase:
+  - `preliminary`: group code string (or `UNASSIGNED`)
+  - `final`: `"1"` or `"2"`
+  - tie-break phases: positive numeric string
+- `round` normalization:
+  - `preliminary`: `1..3`
+  - `final`: `1..2`
+  - tie-break phases: always `1`
+- If another stage is active (started, not ended), API returns `409`.
+
+Response:
+
+- `200 OK` with full updated admin state payload.
+
+### End stage
+
+- Method: `POST`
+- Path: `/api/admin/stage/end`
+- Auth: admin bearer token
+
+Rules:
+
+- Ends the currently active stage by setting `ended_at`.
+- If no active stage exists, API returns `400`.
+
+Response:
+
+- `200 OK` with full updated admin state payload.
+
+## 3) Stage History Endpoint
+
+- Method: `GET`
+- Path: `/api/admin/stage/history`
+- Auth: admin bearer token
+
+Response:
+
+```json
+{
+  "items": [
+    {
+      "id": 1,
+      "phase": "preliminary",
+      "group": "A",
+      "round": 2,
+      "startedAt": "2026-04-30T08:27:13Z",
+      "endedAt": "2026-04-30T08:28:01Z"
+    }
+  ]
+}
+```
+
+## 4) New State Fields
+
+Both endpoints now include these fields:
+
+- `GET /api/state`
+- `GET /api/admin/state`
+
+```json
+{
+  "positionBoards": {
+    "preliminary": {
+      "12": { "groupKey": "A", "position": 1 }
+    },
+    "final": {
+      "12": { "groupKey": "1", "position": 3 }
+    },
+    "prelim_tiebreak": {},
+    "final_tiebreak": {}
+  },
+  "current_stage": {
+    "id": 7,
+    "phase": "preliminary",
+    "group": "A",
+    "round": 2,
+    "startedAt": "2026-04-30T09:00:00Z"
+  },
+  "last_stage": {
+    "id": 6,
+    "phase": "final",
+    "group": "1",
+    "round": 1,
+    "startedAt": "2026-04-30T08:45:00Z",
+    "endedAt": "2026-04-30T08:55:00Z"
+  }
+}
+```
+
+Notes:
+
+- `positionBoards` keys are player IDs as strings.
+- `current_stage` is `null` when no stage is active.
+- `last_stage` is `null` when no stage session has ever started.
+- `last_stage` is the most recently started session (ended or still active).
+
+## Compatibility Impact
+
+- Additive only; existing consumers remain functional.
+- Consumers can ignore unknown fields safely.
+- Consumers needing control/monitoring can use new stage endpoints and fields.

-## API Highlights
+## API Documentation (OpenAPI)
 
-Public:
+Interactive docs are now built in:
 
-- `GET /api/health`
+- Swagger UI: `GET /api/docs`
-- `GET /api/state`
+- OpenAPI JSON: `GET /api/openapi.json`
 
-Admin:
+### Testing with Auth in Swagger UI
 
-- `POST /api/admin/login`
+1. Open `/api/docs`.
-- `POST /api/admin/logout`
+2. Use the **Login & Authorize** form at the top:
-- `POST /api/admin/players`
+   - Username: `datwyler` (default)
-- `PUT /api/admin/players/:id`
+   - Password: `datwyler` (default)
-- `DELETE /api/admin/players/:id`
+3. The page calls `POST /api/admin/login`, retrieves the token, and auto-authorizes Swagger.
-- `PUT /api/admin/scores/:stage/:id`
+4. Use **Try it out** on any admin endpoint.
-- `POST /api/admin/scores/:stage/:id/advice`
-- `POST /api/admin/scores/:stage/reset`
 
-Stages:
+### Stage Values
+
+For score update/proof/advice endpoints (`/api/admin/scores/{stage}/...`), use:
+
+- `prelim_r1`
+- `prelim_r2`
+- `prelim_r3`
+- `final_r1`
+- `final_r2`
+- `prelim_tiebreak`
+- `final_tiebreak`
+
+For reset endpoint (`POST /api/admin/scores/{stage}/reset`), use:
 
 - `preliminary`

+This is a web application written using the Phoenix web framework.
+
+## Project guidelines
+
+- Use `mix precommit` alias when you are done with all changes and fix any pending issues
+- Use the already included and available `:req` (`Req`) library for HTTP requests, **avoid** `:httpoison`, `:tesla`, and `:httpc`. Req is included by default and is the preferred HTTP client for Phoenix apps
+
+### Phoenix v1.8 guidelines
+
+- **Always** begin your LiveView templates with `<Layouts.app flash={@flash} ...>` which wraps all inner content
+- The `MyAppWeb.Layouts` module is aliased in the `my_app_web.ex` file, so you can use it without needing to alias it again
+- Anytime you run into errors with no `current_scope` assign:
+  - You failed to follow the Authenticated Routes guidelines, or you failed to pass `current_scope` to `<Layouts.app>`
+  - **Always** fix the `current_scope` error by moving your routes to the proper `live_session` and ensure you pass `current_scope` as needed
+- Phoenix v1.8 moved the `<.flash_group>` component to the `Layouts` module. You are **forbidden** from calling `<.flash_group>` outside of the `layouts.ex` module
+- Out of the box, `core_components.ex` imports an `<.icon name="hero-x-mark" class="w-5 h-5"/>` component for hero icons. **Always** use the `<.icon>` component for icons, **never** use `Heroicons` modules or similar
+- **Always** use the imported `<.input>` component for form inputs from `core_components.ex` when available. `<.input>` is imported and using it will save steps and prevent errors
+- If you override the default input classes (`<.input class="myclass px-2 py-1 rounded-lg">)`) class with your own values, no default classes are inherited, so your
+custom classes must fully style the input
+
+
+<!-- usage-rules-start -->
+
+<!-- phoenix:elixir-start -->
+## Elixir guidelines
+
+- Elixir lists **do not support index based access via the access syntax**
+
+  **Never do this (invalid)**:
+
+      i = 0
+      mylist = ["blue", "green"]
+      mylist[i]
+
+  Instead, **always** use `Enum.at`, pattern matching, or `List` for index based list access, ie:
+
+      i = 0
+      mylist = ["blue", "green"]
+      Enum.at(mylist, i)
+
+- Elixir variables are immutable, but can be rebound, so for block expressions like `if`, `case`, `cond`, etc
+  you *must* bind the result of the expression to a variable if you want to use it and you CANNOT rebind the result inside the expression, ie:
+
+      # INVALID: we are rebinding inside the `if` and the result never gets assigned
+      if connected?(socket) do
+        socket = assign(socket, :val, val)
+      end
+
+      # VALID: we rebind the result of the `if` to a new variable
+      socket =
+        if connected?(socket) do
+          assign(socket, :val, val)
+        end
+
+- **Never** nest multiple modules in the same file as it can cause cyclic dependencies and compilation errors
+- **Never** use map access syntax (`changeset[:field]`) on structs as they do not implement the Access behaviour by default. For regular structs, you **must** access the fields directly, such as `my_struct.field` or use higher level APIs that are available on the struct if they exist, `Ecto.Changeset.get_field/2` for changesets
+- Elixir's standard library has everything necessary for date and time manipulation. Familiarize yourself with the common `Time`, `Date`, `DateTime`, and `Calendar` interfaces by accessing their documentation as necessary. **Never** install additional dependencies unless asked or for date/time parsing (which you can use the `date_time_parser` package)
+- Don't use `String.to_atom/1` on user input (memory leak risk)
+- Predicate function names should not start with `is_` and should end in a question mark. Names like `is_thing` should be reserved for guards
+- Elixir's builtin OTP primitives like `DynamicSupervisor` and `Registry`, require names in the child spec, such as `{DynamicSupervisor, name: MyApp.MyDynamicSup}`, then you can use `DynamicSupervisor.start_child(MyApp.MyDynamicSup, child_spec)`
+- Use `Task.async_stream(collection, callback, options)` for concurrent enumeration with back-pressure. The majority of times you will want to pass `timeout: :infinity` as option
+
+## Mix guidelines
+
+- Read the docs and options before using tasks (by using `mix help task_name`)
+- To debug test failures, run tests in a specific file with `mix test test/my_test.exs` or run all previously failed tests with `mix test --failed`
+- `mix deps.clean --all` is **almost never needed**. **Avoid** using it unless you have good reason
+
+## Test guidelines
+
+- **Always use `start_supervised!/1`** to start processes in tests as it guarantees cleanup between tests
+- **Avoid** `Process.sleep/1` and `Process.alive?/1` in tests
+  - Instead of sleeping to wait for a process to finish, **always** use `Process.monitor/1` and assert on the DOWN message:
+
+      ref = Process.monitor(pid)
+      assert_receive {:DOWN, ^ref, :process, ^pid, :normal}
+
+   - Instead of sleeping to synchronize before the next call, **always** use `_ = :sys.get_state/1` to ensure the process has handled prior messages
+<!-- phoenix:elixir-end -->
+
+<!-- phoenix:phoenix-start -->
+## Phoenix guidelines
+
+- Remember Phoenix router `scope` blocks include an optional alias which is prefixed for all routes within the scope. **Always** be mindful of this when creating routes within a scope to avoid duplicate module prefixes.
+
+- You **never** need to create your own `alias` for route definitions! The `scope` provides the alias, ie:
+
+      scope "/admin", AppWeb.Admin do
+        pipe_through :browser
+
+        live "/users", UserLive, :index
+      end
+
+  the UserLive route would point to the `AppWeb.Admin.UserLive` module
+
+- `Phoenix.View` no longer is needed or included with Phoenix, don't use it
+<!-- phoenix:phoenix-end -->
+
+<!-- phoenix:ecto-start -->
+## Ecto Guidelines
+
+- **Always** preload Ecto associations in queries when they'll be accessed in templates, ie a message that needs to reference the `message.user.email`
+- Remember `import Ecto.Query` and other supporting modules when you write `seeds.exs`
+- `Ecto.Schema` fields always use the `:string` type, even for `:text`, columns, ie: `field :name, :string`
+- `Ecto.Changeset.validate_number/2` **DOES NOT SUPPORT the `:allow_nil` option**. By default, Ecto validations only run if a change for the given field exists and the change value is not nil, so such as option is never needed
+- You **must** use `Ecto.Changeset.get_field(changeset, :field)` to access changeset fields
+- Fields which are set programmatically, such as `user_id`, must not be listed in `cast` calls or similar for security purposes. Instead they must be explicitly set when creating the struct
+- **Always** invoke `mix ecto.gen.migration migration_name_using_underscores` when generating migration files, so the correct timestamp and conventions are applied

+# Shooting Event Phoenix Backend
+
+This folder contains a Phoenix + SQLite implementation of the existing Go API contract used by the Vue frontend.
+
+## Run (dev)
+
+```bash
+cd phoenix
+mix deps.get
+mix ecto.create
+mix ecto.migrate
+PORT=8080 mix phx.server
+```
+
+Or from project root:
+
+```bash
+make phoenix-dev
+```
+
+## Build
+
+```bash
+make phoenix-build
+```
+
+## API compatibility
+
+The Phoenix app exposes the same `/api/*` endpoints currently used by the Vue app, including:
+
+- Public:
+  - `GET /api/health`
+  - `GET /api/state`
+  - `GET /api/events` (SSE)
+- Admin:
+  - `POST /api/admin/login`
+  - `POST /api/admin/logout`
+  - `GET /api/admin/state`
+  - `PUT /api/admin/settings`
+  - Player CRUD + auto-group
+  - Score/proof update/delete + reset
+  - AI score advice endpoint
+
+## Environment
+
+- `PORT` (default: `8080`)
+- `DB_PATH` (default: `../data/shooting_phoenix.db`)
+- `ADMIN_USER` (default: `datwyler`)
+- `ADMIN_PASS` (default: `datwyler`)
+- `GEMINI_API_KEY` (default follows existing project fallback)
+- `GEMINI_MODEL` (default: `gemini-3.1-flash-lite-preview`)
