Route ACE server commands through the existing chat path, bind the retail paperdoll hit mask instead of its obscured viewport, and prefer authoritative private health vitals. Record the user-confirmed live gate and pin the production DAT widget type in tests.
Three fixes to the Vitals HUD path:
1. EnchantmentMask Vitae/Cooldown bit values (parser regression).
ACE's enum at references/ACE/Source/ACE.Entity/Enum/EnchantmentCategory.cs
has Vitae=0x4 and Cooldown=0x8. I had them swapped — when ACE wrote
the Vitae singleton with mask bit 0x4 set, my parser read it as
"Cooldown" and tried to consume a count-prefixed list (no count
present), blowing up with FormatException, returning null from
TryParse. PlayerDescription consequently failed to parse on every
live login. Fix: swap the bit values + bucket constants to match ACE.
2. Vitae applies regardless of StatModKey. Live trace showed:
vitals: PD-ench spell=666 layer=0 bucket=Vitae key=0 val=0.95
ACE's Vitae enchantment serializes with key=0 (meaning "any vital")
per retail. EnchantmentMath was filtering Vitae by key like other
buffs, so the 5% death penalty never applied to Health/Stam/Mana
max — the Vitals percent read 95% because current=276 / max=290
(server already reduced current; our max didn't match). Fix:
Vitae bucket short-circuits the per-key check and applies its
multiplier to all vitals.
3. Absolute current/max in HUD overlay. VitalsVM exposes
HealthCurrent/Max, StaminaCurrent/Max, ManaCurrent/Max from
LocalPlayerState. VitalsPanel overlay format is now
"current / max (percent%)" when absolutes are available; falls
back to percent-only pre-PlayerDescription. Matches the retail
look the user requested ("HP 400/400" style).
Test deltas (841 -> 842):
- Existing Vitae test still passes (key matches statKey case).
- New Vitae key=0 test pins the "any vital" semantics.
- Existing PlayerDescription Vitae singleton test updated to
write mask=0x4 (was 0x8 with the swapped enum).
Live verification: with +Acdream's Vitae-666 active and Endurance.current=290:
HP : current=138, max=145×0.95≈138 → bar 100% (was 95%)
Stam : current=276, max=290×0.95≈276 → bar 100%
Mana : current=190, max=200×0.95≈190 → bar 100%
Overlay reads e.g. "276 / 276 (100%)".

Closes ISSUES.md #5. The Vitals devtools window now draws three bars
(HP / Stamina / Mana) once the server sends the first PlayerDescription
(0x0013), instead of HP only. Built test-first per CLAUDE.md TDD rule —
16 new tests went red before the implementation went in.
New AcDream.Core.Player.LocalPlayerState (cache):
- {CurrentStamina, MaxStamina, CurrentMana, MaxMana} as uint? — null
until first received.
- StaminaPercent / ManaPercent: 0..1 fraction or null when either
field is missing or max is zero. Clamps to 1.0 if current > max
(server can briefly report this during buff transitions).
- OnPlayerDescription preserves any previously known good value when
an incoming field is null — partial profiles don't wipe state.
- Changed event for future subscribers.
GameEventWiring.WireAll:
- New optional 6th parameter: LocalPlayerState? localPlayer = null.
Existing 5-arg call sites still work; without the parameter the new
PlayerDescription handler still parses + feeds the spellbook but
skips the cache update.
- PlayerDescription (0x0013) shares AppraiseInfo wire format with
IdentifyObjectResponse (0x00C9) per AppraiseInfoParser docstring,
so the new handler reuses the existing parser and pulls
CreatureProfile.{Stamina, StaminaMax, Mana, ManaMax}.
- Player's full learned spellbook also lands here (previously only
item-scoped Identify responses fed the spellbook).
VitalsVM:
- Constructor adds optional LocalPlayerState? parameter (default null
keeps every existing caller compiling).
- StaminaPercent / ManaPercent now read through to LocalPlayerState
every access — no VM-side caching, so a server-side delta to the
cache surfaces next frame without any explicit refresh.
GameWindow:
- Public readonly LocalPlayer field alongside Combat / Chat / Items /
SpellBook so plugins + future panels can bind directly.
- WireAll call updated to pass LocalPlayer.
- VitalsVM construction passes LocalPlayer so the existing
VitalsPanel automatically picks up the two new bars.
Test counts:
- AcDream.Core.Tests: 550 → 561 (+11 LocalPlayerStateTests)
- AcDream.UI.Abstractions.Tests: 23 → 26 (+3 VitalsVM through-cache)
- AcDream.Core.Net.Tests: 192 → 194 (+2 PlayerDescription wiring)
- Total: 765 → 781
Build: 0 warnings, 0 errors.

Adds the backend-agnostic UI contract layer called for by the 2026-04-24
staged UI strategy (docs/plans/2026-04-24-ui-framework.md). This is the
stable layer both the Phase D.2a Hexa.NET.ImGui backend and the later
D.2b custom retail-look backend implement.
New module `src/AcDream.UI.Abstractions/`:
* IPanel — a drawable panel (id/title/visible/Render)
* IPanelHost — owns the panel list, drives per-frame dispatch
* IPanelRenderer — drawing primitives (Begin/End/Text/SameLine/
Separator/ProgressBar). Kept small + retail-friendly
on purpose — if a widget can't be expressed with
dat-sourced sprites+fonts later, don't add it here.
* ICommandBus — user-intent publisher; NullCommandBus is D.2a default
* PanelContext — per-frame record struct (DeltaSeconds + Commands)
* Panels/Vitals/
VitalsVM — reads CombatState.GetHealthPercent for the local
player. Stamina/Mana return null in D.2a; they await
a LocalPlayerState cache of PlayerDescription (0x0013)
which is filed as a follow-up issue.
VitalsPanel — first real panel. HP bar always drawn; Stam/Mana
appear automatically when the VM returns non-null.
Invariant documented in IPanel's XML doc: no `using Hexa.NET.ImGui` in
panel files, ever. If a widget needs something IPanelRenderer can't
express, the interface grows; panels never reach through.
References AcDream.Core for CombatState. Zero runtime/UI dependencies
— this project compiles headless, perfect for unit testing the
ViewModels.
No visible change yet. Next commits: (2) tests, (3) ImGui backend,
(4) GameWindow hookup + visible panel behind ACDREAM_DEVTOOLS=1.
