Real client-side networking for the player controller, verified with a
genuine two-process integration test (an actual dedicated server process
+ a real ENet-connected client), per docs/architecture/networking.md §5.
scripts/network_client.gd: NetworkClient -- predicts movement locally on
input (same movement constants as scripts/player_spawner.gd), sends input
to the server via RPC, and reconciles against the server's authoritative
snapshots when they diverge beyond a threshold.
scripts/network_receiver_proxy.gd + network_player_proxy.gd: the RPC
plumbing that makes this actually route correctly, which took real
debugging to get right:
- Godot's rpc_id() resolves the receiving node by matching the sending
node's NodePath between peers. scripts/server.gd is the SceneTree root
node "Server" when the dedicated server runs, and spawns each player as
"Player_<peer_id>" under itself -- so the client needs its own node
tree at those same paths purely for RPC routing.
- Godot also enforces an RPC "node checksum": both peers must declare the
*same set* of @rpc methods at a matching path, or every RPC at that
path fails, not just a genuinely missing one. Every @rpc method on
scripts/server.gd's root and scripts/player_spawner.gd had to be
mirrored here (mostly as no-op stubs), not just the ones this class
actually calls.
Known, explicitly-scoped simplification (stated in the code, not hidden):
scripts/server.gd's snapshot doesn't currently echo back a per-peer "last
input seq processed", so reconciliation corrects against the most recent
prediction rather than true tick-exact rollback-and-replay
(networking.md §5.2 step 4). A real follow-up once the server echoes
that ack, not faked here.
Verified: real two-process test (godot --headless --path . scenes/
server.tscn as an actual persistent process, a second process running
scripts/smoke_test_network_client.gd against it over real ENet) --
4/4 passing: connects, predicts locally before any server round trip,
sends real input, and a deliberately-desynced position (moved 9999 units
away) gets corrected by the very next real snapshot. Full existing
client suite (10 suites) + 61 backend pytest still passing.

Two genuine bugs, found by reproducing rather than trusting the branch's
own state:
1. scenes/player.tscn collided with PC2's client-side player scene at the
exact same path (server-authoritative PlayerNode vs. the local
single-player character) -- whichever merged last would silently
overwrite the other. The branch's own last commit had literally
committed unresolved <<<<<<< conflict markers into the file instead of
resolving them. Renamed the server's version to
scenes/server_player.tscn, restored scenes/player.tscn to match main's
real client scene exactly, repointed scripts/server.gd's preload.
2. scenes/server.tscn's root Node had no script attached at all -- it only
ever worked before because project.godot had `Server` registered as a
project-wide autoload (the exact wholesale-overwrite this task was
already asked to fix). Once that autoload was correctly removed,
nothing attached server.gd to the scene tree anymore and the dedicated
server silently did nothing. Attached scripts/server.gd directly to
scenes/server.tscn's root node instead.
Verified: godot --headless --import/--quit both clean, full 10-suite
client smoke test all passing, and the dedicated server actually listens
on UDP port 7777 when launched explicitly (`godot --path . scenes/server.tscn`)
-- confirmed with `ss -ulnp`, not just trusting the startup print (first
checked with `ss -tlnp`, which only shows TCP and falsely suggested it
wasn't listening at all; ENet is UDP).

Both were verified (9/9 passing) before PR #50 merged but got lost in the
handoff between my push and the concurrent live agent session reusing the
same workspace -- PR #50's actual merged diff only had the world_list.gd/
player.gd code changes, missing the new test file and the doc update.
Caught while auditing everything feeding PC2 for real completeness.

_show_authenticated() (the session-restore path, used when returning to
main_menu.tscn -- e.g. after clicking Back from world_list) only hid
EmailEdit/Over18Check, unlike _on_auth_complete() (the fresh-login path)
which hides the full form: UsernameEdit, PasswordEdit, EmailEdit,
Over18Check, AuthButton, AuthModeLabel. Play was correctly enabled and
the welcome message was correctly visible, so a check that stopped at
those two passed clean -- but the actual login fields were still on
screen, which is what a real user sees as "it's making me log in again."
Confirmed via live PC1 playtest today.
Reported by: real playtest, 2026-08-20 (yesterday's automated regression
test for this exact Play -> Back flow only asserted Play/welcome/auth
buttons row -- strengthened smoke_test_main_menu_back.gd to also check
the individual form fields, and confirmed it fails exactly this way with
the bug reintroduced before restoring the fix).
Verified against a live backend: 61/61 pytest (unaffected), 8/8 Godot
smoke tests (including 20/20 on the strengthened back-nav test).

Two things, found together while investigating a stuck blocker task:
1. URGENT: main_menu.gd currently fails to parse at all on main
("Identifier '_dob_edit' not declared in the current scope"). PR #44
(hide-all-fields-on-auth-success) and PR #45 (DOBEdit -> Over18Check
checkbox) each merged cleanly on their own -- Gitea's merge reported
mergeable:true for both -- but together they left a reference to the
old _dob_edit var on a line neither PR's diff touched, so no conflict
was ever flagged. Same failure mode in smoke_test_main_menu_full_flow.gd
(dob_edit, would have failed to even parse in the checkpoint suite).
Fixed both to reference _over_18_check / over_18_check.
2. Lands the Play -> Back session-persistence fix (PR #43, task
28357bca192d) that was stuck behind review the whole time main didn't
have it yet: signal auth_state_ready, _show_authenticated() /
_reset_to_logged_out() helpers, and _ready() restoring the
authenticated UI (not resetting it) when ApiClient already holds a
valid token. Plus the real fix a review round caught on top of that
(task 9186405a6373): _show_authenticated() was hiding AuthPanel while
claiming the welcome label inside it was visible -- a no-op UI-wise,
since WelcomeLabel.visible=true does nothing once its parent is
hidden. AuthPanel now stays visible; the regression test
(smoke_test_main_menu_back.gd, new) asserts is_visible_in_tree(), not
just .visible, so this class of bug can't pass silently again.
Verified against a live backend: 61/61 pytest, 7/7 Godot smoke tests
(including the new smoke_test_main_menu_back.gd, 12/12).
