Tyre #1: Added Rust-generated input_batch_two.msgpack fixture for
bidirectional D-030 Layer 1 symmetry (Vec<PlayerInput>).
Tyre #2: Added all_fixtures_deserialize Rust test that reads every
.msgpack fixture and verifies it deserializes (corruption guard).
Hoshe #3: Added test_decode_snapshot_malformed_entities_counted test
verifying the decode_errors counter on D-010 boundary violations.
45 client tests, 54 server tests pass.

Hoshe #1: E2E test now uses random ephemeral port (49152-65535) with
port rotation on bind failure, avoiding conflicts in parallel CI.
Hoshe #2: Documented intentional input drop on encode failure in
SimBridge — re-queuing would retry bad data and server tick has
already advanced.

D-030 Layer 3: E2E test spawns the Rust server binary, connects via
LocalBridge, sends a batched MoveNorth input, and verifies the player
moved to (16.5, 15.5). Also adds batch encoding roundtrip tests,
framed batch test, and Player entity fixture decode test. 43/43 pass.

Server team added EntityKind::Player variant. Added snapshot_player
fixture and updated snapshot_multi_entity to include all 4 entity kinds
(Player, Npc, Object, Terrain) for complete D-030 Layer 1 coverage.

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

12 new tests covering framing roundtrips, cross-layer Protocol+framing
integration, and diagonal wire mapping. 4 new diagonal movement
fixtures generated from Rust for D-030 Layer 1 cross-language
verification. 33/33 tests pass.

- 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

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
.msgpack files using rmp_serde::to_vec_named for cross-language testing.
Fixtures cover: snapshots (empty, one NPC, multi-entity with all
EntityKind variants) and player inputs (unit + data enum variants).

- Fix input_mapper double-check bug (redundant InputEventKey + pressed filter)
- Add bounds checking for position arrays in entity_renderer and game_state
- Make test snapshot deterministic (incrementing counter, not wall clock)
- Fix tween overlap in monologue_display (cancel active tween before new one)
- Extract TILE_SIZE constant from magic number 32
- Add 5 D-030 Layer 1 fixture tests for snapshot parsing (7/7 total passing)

Set up the complete Godot 4.6 client foundation as a pure renderer (D-020):
- project.godot with 2D rendering, autoloads, input actions
- Main scene: Game > World (TileMapLayer, Entities, FogOverlay) + Camera2D + UILayer
- Autoloads: SimBridge (connection state machine + test mode), GameState, InputMapper
- Rendering stubs: WorldRenderer, EntityRenderer, FogRenderer
- UI stubs: HUD (health/perception/time), Minimap, MonologueDisplay
- Input mapping: WASD/arrows, E (interact), Tab (perception), Esc (menu), Space (pause)
- gdUnit4 smoke tests: scene loads, autoloads registered (2/2 passing)
