Server expects a MessagePack array of PlayerInput objects in one framed
message per tick, not individual inputs per frame. Added
Protocol.encode_player_inputs() for batch encoding. Changed SimBridge to
buffer raw input dicts and batch-encode in _process(). Also fixed server
port default (9876) and positional arg format to match server CLI.

Replace expect() with unwrap_or_else that logs the bind address
and error via tracing before exiting.

Snapshot for tick N should show state at END of tick N. Reorder systems
so generate_snapshot runs after validate_movement but before
advance_tick. Previously snapshot.tick was the incremented tick,
not the tick whose inputs were processed. Also fix main.rs accept
error to log address context before exiting.

Replace string-matching disconnect detection with explicit
BridgeError::Disconnected variant. Add TcpBridge::accept_on(listener)
that takes a pre-bound TcpListener, eliminating the 100ms sleep hack
in TCP tests. Send errors now also trigger ServerRunning=false.
Add trace logging to generate_snapshot for entity count visibility.

Critical fixes from Hoshe review:
1. Race condition: defer TCP connect to _process() with retry logic
(MAX_CONNECT_RETRIES=20, 100ms interval) so server has time to bind.
2. Buffer corruption: disconnect on oversized message instead of
clearing valid buffered data (_corrupt flag, fail-safe).
3. Silent input drop: send_input() returns Error so callers can detect
encode/validation failures.
Warnings addressed:
- ServerProcess validates server_path exists before spawning
- SIGKILL and health check TODOs documented for future work
- Diagonal keybindings documented as intentional deferral
- send_message uses single put_data() call (no partial write risk)
- Static frame helpers documented as D-030 Layer 2 test-only
New tests (36 total, up from 33):
- Partial read scenario (chunked TCP delivery)
- Multi-message sequential decode (exercises buffer corruption fix)
- send_input error return on invalid action

Implements the full server-side tick pipeline:
- process_player_input drains InputQueue, converts PlayerActions to
MoveIntent components or pause/unpause toggles
- generate_snapshot builds ObserverSnapshot from ECS state with
render coordinate conversion
- receive_bridge_inputs/send_bridge_snapshot handle bridge I/O with
graceful disconnect detection via ServerRunning resource
- main.rs now accepts TCP connections and runs a proper game loop
- PlayerCharacter marker, Player EntityKind, SnapshotBuffer resource
Closes server side of #81, #82, #83.

Godot has no Unix socket API, so TCP localhost is required for
client-server IPC. TcpBridge implements SimBridge with the same
framing protocol as LocalBridge. Includes accept/connect methods
and three integration tests over TCP.

Client-side Protocol.gd expects rmp_serde::to_vec_named() (maps with
string keys), but LocalBridge was using to_vec() (compact positional
arrays). Fix send_snapshot and update all test serialization calls to
match actual wire format. Also change EOF from Ok(vec![]) to
BridgeError::Transport so bridge systems can detect disconnects.

12 new tests covering framing roundtrips, cross-layer Protocol+framing

Wire SimBridge to use LocalBridge for TCP transport in non-test mode:
_process() polls for incoming snapshots and flushes outbound inputs.
Add 4 diagonal movement variants (NE, SE, SW, NW) to InputMapper and
wire mapping, ordered clockwise. Register diagonal input actions in
project.godot.

LocalBridge wraps StreamPeerTCP with 4-byte big-endian length-prefix

validate_movement now checks both terrain walkability AND tile
occupancy. Builds a spatial index of occupied tiles from stationary
entities, then resolves movers in order — first valid claim wins.
Same spatial pattern needed for D-026 simulation tiers (30-80 active
NPCs) and future pathfinding occupied-tile awareness.

Add diagonal PlayerAction variants (MoveNortheast, MoveNorthwest,
MoveSoutheast, MoveSouthwest) and TilePosition::all_neighbors()
returning all 8 surrounding tiles. Genre-expected for immersive sim.
Establishes the movement pattern before pathfinding is built on top.

- decode_snapshot() reports dropped entities via push_error and returns
decode_errors count so callers can detect partial data (D-010
information boundary compliance)
- receive_bytes() warns when overwriting unconsumed snapshot, documents
latest-wins semantics
- Rename misleading test to test_encode_produces_nonempty_bytes
- Fix tick rate comment: 10 ticks/game-minute per D-031

Hoshe critical fixes:
- _action_enum_to_wire uses InputMapper.Action constants instead of
fragile integer literals; OPEN_MENU explicitly handled as client-only
- Remove int() coercion on tick/entity_id — use direct assignment since
GDScript int is signed 64-bit (safe for realistic tick values)
- Check encode result before buffering in send_input() — reject empty
bytes instead of corrupting the outbound stream
- Test snapshot now uses Protocol format {tick, entities} instead of
legacy schema; GameState updated to derive player position from
entity data; main.gd and world_renderer.gd updated accordingly
Hoshe warnings:
- 5 negative tests added (truncated bytes, wrong type, missing fields,
empty bytes, encode validation) — 20/20 tests pass
- receive_bytes signal is emitted at consume time in poll_snapshot by
design (documented in code)
Tyre suggestions:
- Remove duplicated root-level fixtures — single source of truth in
client/tests/fixtures/msgpack/
- gen_fixtures.rs writes directly to client/ directory
- Add `make fixtures` target for regeneration

SimBridge now encodes player inputs via Protocol.encode_player_input()
and exposes receive_bytes()/drain_outbound() for the transport layer.
Test mode still works unchanged. Transport (ticket #79) will call
these methods to complete the IPC pipeline.

Protocol.gd decodes ObserverSnapshot and PlayerInput from Rust's
rmp_serde wire format, and encodes PlayerInput for sending to server.
Handles rmp_serde enum encoding: unit variants as bare strings,
data variants as single-element maps.
8 fixture-based tests verify decode of Rust-generated fixtures,
GDScript encode/decode roundtrips, and cross-language compatibility.
All 15 tests pass (3 suites).

Install Godot4MessagePack (pure GDScript) for MessagePack encode/decode.
Add Rust fixture generator (gen_fixtures.rs) that produces canonical

EntityKind variants) and player inputs (unit + data enum variants).
