## Central HTTP client singleton (autoload name: "ApiClient").
##
## Every network call in the game flows through this class. Callers use the
## high-level helpers ([method login], [method register], [method get_worlds],
## [method health_check], [method get_me]) or the generic [method request]
## primitive. All results conform to the result-dictionary contract below.
##
## [b]Result Dictionary Contract[/b]
## Every public method returns (after `await`) a Dictionary with this shape:
##
## {
## "ok": bool, # true for HTTP 2xx, false otherwise
## "status": int, # HTTP status code (0 on network failure)
## "data": Variant, # parsed JSON body on success (null otherwise)
## "detail": String, # human-readable message
## }
##
## Network failures (timeout / DNS / refused connection) return `status == 0`
## with a `detail` describing the transport failure. Non-2xx responses return
## the real HTTP status and the backend's `detail` field from the JSON error
## body when present. No caller can crash on a failed request.
##
## [b]Token storage[/b]
## JWTs are kept in memory. [method set_token] is the single seam for future
## disk persistence (override it to save to `user://`).
##
## [b]Usage[/b]
## var result: Dictionary = await ApiClient.login("alice", "secret")
## if result.ok:
## print("Logged in!")
## else:
## print("Error: ", result.detail)

class_name ChunkStreamManager
extends Node
## Manages loading and unloading of world chunks based on player position.
##
## This is the central orchestrator for the chunk streaming system. It monitors
## the player's position, determines which chunks should be loaded, requests
## chunk data from the server, instantiates ChunkScene nodes, and unloads
## chunks that fall outside the streaming radius.
##
## ## Design
##
## - **Streaming radius** defines how many chunks around the player are kept
## loaded. Chunks beyond this radius are unloaded to save memory and CPU.
## - **Load priority** ensures chunks closer to the player are loaded first,
## preventing visual pop-in at the edge of the view.
## - **Server communication** uses the RPCs defined in docs/architecture/world.md
## (§5.3): `request_chunk`, `chunk_data`, `chunk_invalidated`.
##
## ## Usage
##
## Add this node to your scene tree and set the `player` reference:
## ```gdscript
## var stream_manager: ChunkStreamManager = $ChunkStreamManager
## stream_manager.player = $Player
## stream_manager.streaming_radius = 4 # chunks
## ```
## Number of chunks (radius) to keep loaded around the player.
## A radius of 2 means a 5x5 grid of chunks centered on the player.
## Higher values increase memory usage but reduce streaming pop-in.
@export var streaming_radius: int = 3
## Maximum number of chunks to load per frame. Prevents frame spikes during
## rapid movement or when entering a new area.
@export var max_loads_per_frame: int = 4
## Maximum number of chunks to unload per frame.
@export var max_unloads_per_frame: int = 4
## Distance (in chunks) from the streaming radius edge before a chunk is
## considered for unloading. Prevents rapid load/unload cycling.
@export var unload_margin: int = 1

extends Control
## Main menu with login/register UI wired to the backend auth API.
##
## The AuthPanel is hidden by default. When the user clicks the LoginButton or
## RegisterButton (AuthButtonsRow, above the panel), the auth panel slides in.
## The Login and Register buttons on the AuthButtonsRow directly set the panel's
## mode, so the user can switch between Login and Register at any time while
## the panel is open.
##
## On successful auth the token is stored via ApiClient, AuthButtonsRow hides,
## the welcome label shows the username, and the Play button becomes enabled.
## The auth form fields are hidden, leaving only the welcome message visible.
##
## When returning from another scene (e.g. world_list), _ready() checks whether
## ApiClient already holds a valid token. If so, it restores the authenticated
## UI state (Play enabled, welcome message visible) instead of forcing the user
## back to the login form.
## Emitted once _ready()'s session check (has_token() + the awaited
## get_me() call) has actually resolved, whichever way -- lets a test (or
## anything else) know the UI state is trustworthy now, rather than
## guessing from a frame count or from UI properties that are ambiguous
## mid-await (e.g. AuthButtonsRow.visible is true both before the check
## resolves AND in a genuine logged-out end state).

## Regression test for the Play -> Back navigation bug.
##
## The reported bug: after logging in and clicking Play, the user lands on
## world_list.tscn; clicking Back returns to main_menu.tscn, but the menu
## reset to a fully logged-out state (Play disabled, login form showing)
## even though ApiClient still held a valid token. main_menu.gd's _ready()
## used to unconditionally reset the UI on every scene load.
##
## This test drives the real navigation flow (change_scene_to_file) against
## a live backend:
## 1. Register a unique user so ApiClient holds a valid token.
## 2. Load main_menu.tscn and assert it restores the authenticated state.
## 3. Click Play -> world_list.tscn.
## 4. Click Back -> main_menu.tscn.
## 5. Assert the menu is STILL authenticated (Play enabled, welcome label
## actually visible in the tree, login/register buttons hidden).

## Headless smoke test for the world list screen.
##
## Run with:
## godot --headless --path . --script res://scripts/smoke_test_world_list.gd
##
## Requires the backend to be running (default base URL
## `application/agp/api_base_url` -> http://127.0.0.1:8000, override with
## AGP_API_BASE_URL).
##
## Unlike a pure API-level test, this actually instantiates scenes/
## world_list.tscn as a real scene and adds it to the tree -- catches
## @onready node-path bugs (a node reference pointing at the wrong path
## errors right here, not just "looks right" from reading the script) that
## an API-only test would miss entirely.
##
## Tests:
## 1. Register + log in a fresh user (so get_worlds() has a valid token).
## 2. POST a real world via the API so the populated-card path actually
## gets exercised -- run_checkpoint_tests.py always starts from a
## genuinely empty DB, so without this the card-rendering code below
## would never run in CI at all, only the empty-list path would.
## 3. Instantiate world_list.tscn, add to tree -- @onready resolution
## must not error.
## 4. Wait for _refresh_worlds()'s awaited request to complete.
## 5. Confirm it actually reached the populated (not empty) state, and
## that the rendered card has a real width -- not just non-zero
## child_count. 2026-08-20: a real bug shipped where every card
## technically existed in the tree (child_count > 0, no error, no
## crash) but rendered at 1.0px wide because size_flags_horizontal/
## vertical used the raw integer 4 (Control.SIZE_SHRINK_CENTER)
## instead of 3 (Control.SIZE_EXPAND_FILL) on ScrollContainer -- a
## child-count check alone would never catch that, only a real size
## assertion does.
