Replaces NullCommandBus.Instance in PanelContext with a real
LiveCommandBus when a live session is active. Panels publish
SendChatCmd; the host routes it to the right wire opcode + emits
a ChatLog.OnSelfSent local echo (optimistic; retail-equivalent
for Talk).
Pieces:
- ChatChannelKind enum (UI.Abstractions) - mirrors holtburger's
ChatChannelKind (references/holtburger/.../client/types.rs:35-49).
- SendChatCmd record (UI.Abstractions) - (Channel, TargetName?, Text).
- LiveCommandBus (UI.Abstractions) - single-handler-per-type;
Register<T> throws on double-register; Publish<T> logs missing
handler but does not throw.
- ChannelResolver (UI.Abstractions) - port of holtburger's
resolve_legacy_channel (client/commands.rs:50-62) mapping
ChatChannelKind to legacy ChatChannel ids verbatim from
holtburger-protocol/.../chat/types.rs:8-24 (Fellow=0x0800,
AllegianceBroadcast=0x02000000, Vassals=0x1000, Patron=0x2000,
Monarch=0x4000, CoVassals=0x01000000).
- WorldSession.SendTalk / SendTell / SendChannel - 3-line wrappers
around existing ChatRequests.Build* + SendGameAction. Internal
GameActionCapture seam + InternalsVisibleTo for tests.
- GameWindow registers SendChatCmd handler: Say -> SendTalk +
ChatLog echo, Tell -> SendTell + echo, channel kinds ->
ChannelResolver.Resolve -> SendChannel + echo.
12 new tests across SendChatCmd + LiveCommandBus + ChannelResolver
+ WorldSessionChat. NullCommandBus.Instance retained for back-compat
when no live session.
Solution total: 893 green (51 + 229 + 613).

Central registration helper that wires every parsed GameEvent from the
Phase F.1 dispatcher into the appropriate Core state class:
- ChannelBroadcast / Tell / CommunicationTransientString / PopupString
→ ChatLog (H.1)
- UpdateHealth / Victim / Defender / Attacker / EvasionAttacker /
EvasionDefender / AttackDone → CombatState (E.4)
- MagicUpdateSpell / MagicRemoveSpell / MagicUpdateEnchantment /
MagicRemoveEnchantment / MagicDispelEnchantment /
MagicPurgeEnchantments → Spellbook (E.5)
- WieldObject / InventoryPutObjInContainer → ItemRepository (F.2)
This is the piece that makes the dispatcher go from "thing that routes
opcodes" to "thing that populates state the UI can redraw from". Before
this, every handler had to be wired at each call site; now one call
at startup (or per-reconnect) does the whole map.
Project graph: added AcDream.Core.Net → AcDream.Core ProjectReference
so the wiring can see both the dispatcher (Net) and the state classes
(Core). Net's own tests already pull in Core indirectly, so test scope
is unchanged.
Tests (6 new, in Core.Net.Tests): verify round-trip via the actual
dispatcher. Build envelope → dispatch → assert the correct Core state
change. Covers ChannelBroadcast, UpdateHealth, MagicUpdateSpell,
WieldObject, PopupString, MagicPurgeEnchantments.
Build green, 602 tests pass (up from 596).

First step of Phase 4 (networking). Adds a new AcDream.Core.Net project
for the AC UDP protocol implementation and a matching AcDream.Core.Net.Tests
project. Keeps networking isolated from rendering and the dat layer,
which also keeps the AGPL-reference-material hygiene cleaner.
AcDream.Core.Net/NOTICE.md documents the attribution policy: we read
ACE's AGPL network code (and holtburger's Rust ac-protocol crate) to
understand AC's wire format, but we reimplement everything in acdream's
own style. Wire-format facts aren't copyrightable; specific code is.
This commit adds one component: IsaacRandom — AC's variant of Bob
Jenkins' ISAAC PRNG, used to XOR a keystream into the CRC field of
every outbound packet for authentication. Clean-room reimplementation
based on reading:
- references/ACE/Source/ACE.Common/Cryptography/ISAAC.cs (AGPL oracle)
- Bob Jenkins' public ISAAC algorithm description
Implementation notes:
- 256 uint32 mm[] state, 256 uint32 rsl[] output buffer, a/b/c regs
- Initialize() runs 4 golden-ratio Mix() warmup rounds then two fold-in
passes over rsl[] and mm[] (fresh instance → both start as zeroes)
- AC variant: seed is exactly 4 bytes, interpreted as little-endian
uint32 assigned to a = b = c before the first Scramble()
- Scramble() produces 256 output words in one pass; Next() consumes
them backwards from offset 255 → 0, re-scrambling at offset -1
- Test seed 0x12345678 matches ACE's reference output byte-for-byte
across the first 16 values (golden vectors transcribed from a
throwaway oracle harness that compiled ACE's ISAAC.cs and printed
its output; the harness was deleted after extracting the values)
Tests (5, all passing):
- Next_Seed12345678_MatchesAceGoldenVectors: 16 golden uint32 values
- Next_TwoInstancesSameSeed_ProduceIdenticalSequence: 1000 outputs
- Next_DifferentSeeds_ProduceDifferentFirstOutput
- Next_512Calls_SpansTwoScrambleBatches: >400 distinct values in 512
outputs (catches all-zero / stuck-at-one bugs at scramble boundary)
- Ctor_ShortSeed_Throws
Both test projects still green: 77 core + 5 net = 82/82.
Phase 4.2 (packet framing + checksum) next.
