# acdream — known issues + small deferred features

Rolling tactical list. What goes here:

- **Bugs**: user-visible defects we've observed but haven't fixed yet.
- **Small deferred features**: work that fits in one or two commits.
  Anything larger should be a named Phase in the [roadmap](plans/2026-04-11-roadmap.md).

What does NOT go here:

- Large multi-commit work → add a Phase to the roadmap instead.
- Ideas / wishlist → `docs/plans/`.
- Design questions → open a `docs/research/*.md` note.

## Conventions

- Sequential integer IDs (`#1`, `#2`, …). Commits that close an issue reference the ID in the message (e.g. `fix #3: periodic TimeSync parsing`).
- `Status` is `OPEN`, `IN-PROGRESS`, or `DONE`. DONE items move to the **Recently closed** section at the bottom with closed-date + commit SHA.
- Every session: scan OPEN issues at start; promote/close anything we touched during the session before ending.
- Promoting to a Phase: mark as `DONE (promoted to Phase X)` + commit SHA where the Phase entry landed.

# Active issues

## #L.1 — Hotbar UI panel

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** ui / hotbar

**Description:** Number keys 1-9 are bound to `UseQuickSlot_1..9`
actions but no panel exists. Actions fire (visible via the `[input]`
console log) but produce no visible result. Phase L feature: drag-drop
hotbar with up to 5 bars × 9 slots, drag spell/skill icons to slots,
key activates the slot's contents. Server-side: `CreateShortcutToSelected`
(action 0x0A9 in retail motion table) sends a `UseSelected` on slot
fire.

**Files:** `src/AcDream.UI.Abstractions/Panels/Hotbar/` (TBC).

**Acceptance:** Drag an item or spell into slot 1, press `1`, server
responds as if the user clicked the item.

---

## #L.2 — Spellbook favorites panel

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** ui / magic

**Description:** In `MagicCombat` scope, 1-9 should fire
`UseSpellSlot_1..9` (distinct from hotbar). Requires a small UI to
pin favorite spells + a spellbook tab nav. Cross-references issue
#L.3 (combat-mode dispatch).

---

## #L.3 — Combat-mode tracking + scope-aware Insert/PgUp/Delete/End/PgDn dispatch

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** input / combat

**Description:** Insert/PgUp/Delete/End/PgDn mean different things in
melee / missile / magic combat modes (per retail keymap MeleeCombat /
MissileCombat / MagicCombat blocks). Phase K has the bindings and the
scope stack; what's missing: `CombatState.CurrentMode` field +
listener for the server-side `SetCombatMode` packet (likely 0x0053 or
similar — confirm against ACE source). When mode arrives, push the
appropriate scope; when leaving combat, pop.

---

## #L.4 — F-key panels: Allegiance / Fellowship / Skills / Attributes / World / SpellComponents

**Status:** OPEN
**Severity:** LOW
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** ui

**Description:** Retail F3-F6, F8-F12 toggle UI panels for various
character data. Phase K has the bindings (`ToggleAllegiancePanel`,
`ToggleFellowshipPanel`, `ToggleSpellbookPanel`,
`ToggleSpellComponentsPanel`, `ToggleAttributesPanel`,
`ToggleSkillsPanel`, `ToggleWorldPanel`, `ToggleInventoryPanel`); the
panels themselves don't exist. Each is its own design feature.
Inventory (F12) is the most-requested.

---

## #L.5 — Floating chat windows (Alt+1-4)

**Status:** OPEN
**Severity:** LOW
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** ui / chat

**Description:** Alt+1..4 toggle four floating chat windows in retail.
Phase K binds the actions; `ChatPanel` currently is a single window.
Floating windows would need filtered-by-channel-type chat tail
rendering.

---

## #L.6 — UI layout save/load (saveui / loadui / lockui)

**Status:** OPEN
**Severity:** LOW
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** ui

**Description:** Retail had `@saveui <name>`, `@loadui <name>`,
`@lockui` commands for persisting ImGui-style window layouts. ImGui
has built-in `LoadIniSettingsFromMemory` /
`SaveIniSettingsToMemory` — wire these to per-named-layout files,
plus chat-command parsing for the `@` prefixes.

---

## #L.7 — Joystick / gamepad bindings

**Status:** OPEN
**Severity:** LOW
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** input

**Description:** Retail keymap declares 11 Joystick devices in the
`Devices` block but no actions are bound by default. acdream uses
Silk.NET keyboard+mouse only. Adding Silk.NET joystick support + a
`JoystickInputSource` adapter would unlock controller play.
`KeyChord.Device` byte already supports values >1, so the binding
side is ready.

---

## #L.8 — Plugin / scripting / macro input subscription

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-26 (deferred from Phase K)
**Component:** plugin / input

**Description:** CLAUDE.md goal: "Build acdream's plugin API to
support scripting/macros for player automation." Plugins should be
able to register custom actions (with namespaced IDs like
`mymacro.heal-rotation`) and subscribe to `InputAction` events. Phase K
foundation supports this via the multicast `InputDispatcher`; what's
missing is the plugin-API surface.

## #1 — Rain falls only to horizon, not to the player's feet

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-25
**Component:** weather / particles

**Description:** During Rainy DayGroups, rain particles are visible in the upper sky band but fade out before reaching the camera / ground level. Retail's rain falls all the way past the camera to the terrain.

**Root cause / status:** Unknown. Likely one of: (a) particle emitter volume too short in Z, (b) particle lifetime shorter than the time it takes to traverse emitter-top → ground, (c) emitter anchored in world-space so particles escape the player's reference frame as they fall, (d) camera-relative spawn origin is offset too high above the player.

**Files:**
- `src/AcDream.App/Rendering/GameWindow.cs` — `UpdateWeatherParticles` (~line 4591)
- `src/AcDream.Core/Vfx/ParticleSystem.cs` — emitter spawn config + lifetime integration

**Research:** `docs/research/deepdives/r12-weather-daynight.md` (rain mechanism — but does not pin volume / lifetime values).

**Acceptance:** Standing at 9,115 in Holtburg during a Rainy DayGroup, rain drops visibly fall all the way from the sky band past the camera to the ground level.

---

## #2 — Lightning visual not wired (dat-baked PES triggers)

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-25
**Component:** weather / sky / vfx

**Description:** Retail's Rainy DayGroup in the Dereth Region dat contains 12+ `SkyObject` entries with non-zero `PesObjectId` and narrow visibility windows (5–70 ms at keyframe-boundary moments) that drive PhysicsScript-authored flash + thunder effects. We render the sky meshes but ignore the PES path, so no lightning flashes appear during storms. The fragment-shader flash bump on `uFogParams.z` is already wired in `sky.frag` — only the CPU-side PES→runner wire is missing.

**Root cause / status:** Research complete. Implementation is: in `SkyRenderer.Render`, detect visibility-window entry on any SkyObject with `obj.PesObjectId != 0`, call `PhysicsScriptRunner.Play(pesObjectId, ownerId: sky-owner, anchorPos: camera)`, and route any `SetFlash` / `Sound` hooks from the script into `uFogParams.z` + audio.

**Files:**
- `src/AcDream.App/Rendering/Sky/SkyRenderer.cs` — add per-SkyObject PES dispatch inside the visibility loop
- `src/AcDream.Core/Vfx/PhysicsScriptRunner.cs` — already shipped (Phase 6a); exposes `Play(scriptId, entityId, anchorWorldPos)`
- `src/AcDream.Core/Lighting/SceneLightingUbo.cs` — `FogParams.Z` is the flash slot; needs a sink that bumps it and decays
- `src/AcDream.App/Rendering/Shaders/sky.frag` — flash bump already wired (`rgb += flash * vec3(1.5, 1.5, 1.8)`)

**Research:**
- `docs/research/2026-04-23-lightning-real.md` (decompile trace + dat discovery)
- `docs/research/2026-04-23-physicsscript.md` (runtime semantics)
- `docs/research/2026-04-23-lightning-crossfade.md` (crossfade mechanism)

**Acceptance:** During a Rainy DayGroup's storm window, visible flashes appear in the sky at the dat-scripted moments, the fragment-shader flash bump briefly brightens the scene, and (later, once thunder audio is wired) a thunder clap plays with a short propagation delay.

## #3 — Client clock drifts from retail after ~10 minutes (periodic TimeSync missing)

**Status:** OPEN
**Severity:** MEDIUM
**Filed:** 2026-04-25
**Component:** net / sky

**Description:** Our `WorldTimeService.DayFraction` syncs with the server once at login via `ConnectRequest + TimeSync`, then advances from the local wall-clock. Retail receives periodic `TimeSync` refreshes (header flag `0x1000000`) carrying a fresh `PortalYearTicks double` and re-anchors its clock. Without those, acdream's keyframe state drifts from retail's over 10+ minutes — observed during the 2026-04-24 sky-color debug sessions where retail was at DayFraction 0.976 while acdream was at 0.634.

**Root cause / status:** Mechanism is well-understood (see research). `WorldTimeService.SyncFromServer(double)` already exists — we just need to detect the periodic flag in the packet header and call it whenever a fresh tick arrives.

**Files:**
- `src/AcDream.Core.Net/WorldSession.cs` — header-flag parsing; currently only the initial sync is consumed
- `src/AcDream.Core/World/WorldTimeService.cs` — `SyncFromServer(double ticks)` ready; needs caller wiring

**Research:** `docs/research/deepdives/r12-weather-daynight.md` §TimeSync (line ~563). References retail packet-header flag `0x1000000` carrying `PortalYearTicks double`.

**Acceptance:** Probe retail via `tools/RetailTimeProbe` and acdream's ACDREAM_DUMP_SKY log at the same wall-clock moment after a 20-minute session without re-login; `abs(acdream.DayFraction - retail.DayFraction) < 0.01`.

## #13 — PlayerDescription trailer past enchantments (options / shortcuts / hotbars / desired_comps / spellbook_filters / options2 / gameplay_options / inventory / equipped)

**Status:** OPEN
**Severity:** LOW (no current user-visible bug; future panels will need the data)
**Filed:** 2026-04-25
**Component:** net / player-state

**Description:** `PlayerDescriptionParser` walks through enchantments (Phase H, 2026-04-25). The trailer beyond that — Options1 / Shortcuts / HotbarSpells (8 lists) / DesiredComps / SpellbookFilters / Options2 / GameplayOptions blob / Inventory / Equipped — is not yet parsed. Required for future Spellbook UI panel, hotbar UI, inventory UI, character options panel.

**Root cause / status:** Holtburger `events.rs:462-625` has the full layout. The trickiest piece is `gameplay_options` — a variable-length opaque blob; holtburger uses a heuristic forward search (`find_inventory_start_after_gameplay_options`) for plausibly-aligned inventory-count + GUID pairs to find the inventory start. Other sections are well-formed.

**Files:**
- `src/AcDream.Core.Net/Messages/PlayerDescriptionParser.cs` — extend `Parsed` record + walker.
- `tests/AcDream.Core.Net.Tests/PlayerDescriptionParserTests.cs` — add fixtures per section.
- `src/AcDream.Core.Net/GameEventWiring.cs` — route `parsed.Inventory` + `Equipped` to ItemRepository.

**Research:** holtburger `events.rs:462-625`; `references/actestclient/TestClient/messages.xml`.

**Acceptance:** All sections of a real-world PlayerDescription parse to completion (no truncation). New tests cover synthetic fixtures per section. `ItemRepository.Count` after login > 0.

## #4 — Sky horizon-glow disabled (fog-mix skipped on sky meshes)

**Status:** OPEN
**Severity:** LOW (aesthetic feature-parity, not regression from pre-session state)
**Filed:** 2026-04-25
**Component:** sky

**Description:** Phase 8.1 (commit `593b76f`) disabled the fog-mix on sky meshes to fix the "entire dome swallowed by fog color" regression. Dereth's keyframe `FogEnd` values (0–2400 m) are calibrated for terrain; sky meshes are authored at radii 1050–14271 m so every sky pixel was past `FogEnd`, saturated to `uFogColor`, destroying stars / moon / dome texture. Disabling the mix restored visibility but we lost retail's horizon-glow effect (gradient from clear zenith to fog-tinted horizon band at dusk/dawn).

**Root cause / status:** Three competing hypotheses, none pinned down: (a) retail uses a **different** fog range for sky than terrain; (b) retail applies fog with an **elevation-angle** weighting rather than linear distance; (c) retail's sky meshes **don't participate** in the global fog and the "horizon glow" comes from a different atmospheric-scatter path. Need to identify retail's actual sky-fog behaviour before re-enabling with correct parameters.

**Files:**
- `src/AcDream.App/Rendering/Shaders/sky.frag` — line ~55, `rgb = mix(uFogColor.rgb, rgb, vFogFactor)` currently commented out
- `src/AcDream.App/Rendering/Shaders/sky.vert` — lines 109-114, `vFogFactor` computation

**Research:** `docs/research/2026-04-23-sky-fog.md`. Partial; doesn't pin the sky-specific fog path.

**Acceptance:** At dusk in Holtburg, the sky dome shows a clear zenith and a warm fog-tinted horizon band that matches retail's appearance, with stars / moon / sun / clouds all still visible at their correct brightnesses elsewhere in the frame.

**Closed:** 2026-04-26
**Commit:** `af74eac`
**Resolution:** Auto-enter player mode at login (one-shot guard
reusing the existing Tab handler logic); MMB-hold mouse-look

**Closed:** 2026-04-26
**Commit:** `da18910`
**Resolution:** ~149 retail-faithful bindings byte-precise to
`docs/research/named-retail/retail-default.keymap.txt`;
`%LOCALAPPDATA%\acdream\keybinds.json` with merge-over-defaults
migration; acdream debug F-keys relocated to `Ctrl+F*`.

**Closed:** 2026-04-26
**Commit:** `256e962`
**Resolution:** Drop the legacy mouse-X-character-yaw path; fix
`WantCaptureMouse` gating; single input path via the multicast
`InputDispatcher`.

---

**Closed:** 2026-04-26
**Commit:** `84512d3`
**Resolution:** Action enum, multicast `InputDispatcher` with scope
stack, `KeyChord` / `Binding` / `KeyBindings`, Silk.NET adapters;
parallel to existing handlers (no behavior change).

---

## #20 — [DONE 2026-04-25] CombatChatTranslator — retail-faithful combat-text formatters

**Closed:** 2026-04-25
**Commit:** `3d26c8e`
**Resolution:** Retail-faithful combat-text formatters into `ChatLog` ("You hit drudge for 50 slashing damage"). Subscribes to `CombatState`'s `DamageTaken` / `DamageDealtAccepted` / `EvadedIncoming` / `MissedOutgoing` / `AttackDone` / `KillLanded` events; templates ported verbatim from holtburger `panels/chat.rs:221-308`.

---

## #19 — [DONE 2026-04-25] TurbineChat codec (0xF7DE) + ChatChannelInfo

**Closed:** 2026-04-25
**Commit:** `ca968fc`
**Resolution:** Full `0xF7DE` codec with three payload variants (`EventSendToRoom`, `RequestSendToRoomById`, `Response`), UTF-16LE strings with variable-length prefix, `SetTurbineChatChannels (0x0295)` parser, unified `ChatChannelInfo` (Legacy + Turbine variants), `TurbineChatState`. **Note: ACE doesn't run a TurbineChat server — codec is ready for retail-server-emulating setups.**

---

## #18 — [DONE 2026-04-25] Holtburger inbound chat parity + Windows-1252 codec

**Closed:** 2026-04-25
**Commit:** `ff5ed9e`
**Resolution:** `EmoteText (0x01E0)` / `SoulEmote (0x01E2)` / `ServerMessage (0xF7E0)` / `PlayerKilled (0x019E)` parsers + `WeenieError` routing through `GameEventWiring`. Global codec switch from `Encoding.ASCII` to `Encoding.GetEncoding(1252)`; matches retail + holtburger; accented names round-trip correctly.

---

## #17 — [DONE 2026-04-25] ChatPanel input field + slash commands

**Closed:** 2026-04-25
**Commit:** `f14296c`
**Resolution:** `ChatPanel` gains Enter-to-submit input field; `ChatInputParser` recognises `/say` `/t` `/tell` `/r` `/g` `/f` `/a` `/m` `/p` `/v` `/cv` `/lfg` `/trade` `/role` `/society` `/olthoi`; `ChatVM` tracks `LastIncomingTellSender` for `/r` reply.

---

## #16 — [DONE 2026-04-25] LiveCommandBus + WorldSession chat senders

**Closed:** 2026-04-25
**Commit:** `8e6e5a0`
**Resolution:** Real `ICommandBus` impl + `WorldSession.SendTalk` / `SendTell` / `SendChannel` wrappers + `SendChatCmd` record + `ChannelResolver` legacy-id mapping per holtburger.

---

## #15 — [DONE 2026-04-25] DebugPanel migration

**Closed:** 2026-04-25
**Commit:** `56037a4`
**Resolution:** Migrates the 473-LOC StbTrueTypeSharp `DebugOverlay` to an ImGui `DebugPanel` with collapsing-headers + checkbox diagnostics + combat-event tail. Deletes `DebugOverlay.cs`; `TextRenderer` + `BitmapFont` kept for future HUD-in-world (D.6 damage floaters, name plates).

---

## #14 — [DONE 2026-04-25] IPanelRenderer widget extension

**Closed:** 2026-04-25
**Commit:** `b131514`
**Resolution:** Adds 14 widget signatures (`TextColored` / `Checkbox` / `Combo` / `InputTextSubmit` / `BeginTable` / etc.) to `IPanelRenderer` + `ImGuiPanelRenderer` impl. Foundation for I.2 DebugPanel and I.4 ChatPanel input.

---

## #7 — [DONE 2026-04-25] PlayerDescription parser stops after spells (enchantment block parsed)

**Closed:** 2026-04-25
**Commit:** `feat(net): #7 PlayerDescriptionParser — enchantment block walker + StatMod flow`
**Resolution:** Extended `PlayerDescriptionParser` past the spell block to parse the Enchantment trailer per holtburger `events.rs:462-501`. Added `EnchantmentEntry` record with full wire payload (16 fields including the `StatMod` triad — type/key/val) + `EnchantmentBucket` (Multiplicative / Additive / Cooldown / Vitae per `EnchantmentMask`). `Parsed` now exposes `IReadOnlyList<EnchantmentEntry> Enchantments`. `GameEventWiring` routes each entry through the new `Spellbook.OnEnchantmentAdded(ActiveEnchantmentRecord)` overload with `StatModType` / `StatModKey` / `StatModValue` / `Bucket` populated. 2 new parser tests cover the enchantment block schema + Vitae singleton.

The remaining trailer sections (options / shortcuts / hotbars / inventory / equipped) are not yet parsed; filed as #13. Stopping after enchantments is intentional — it covers the highest-value section (issue #6 lights up) and avoids the heuristic `gameplay_options` walker that #13 needs.

---

## #12 — [DONE 2026-04-25] Capture full Enchantment wire payload (StatMod) on ActiveEnchantmentRecord

**Closed:** 2026-04-25
**Commit:** `feat(net): #7 PlayerDescriptionParser — enchantment block walker + StatMod flow`
**Resolution:** Closed alongside #7 in the same commit. `ActiveEnchantmentRecord` extended with optional `StatModType`, `StatModKey`, `StatModValue`, `Bucket` fields. `Spellbook` got an `OnEnchantmentAdded(ActiveEnchantmentRecord)` overload that accepts the full record. `EnchantmentMath.GetMod` aggregator now consumes the StatMod data: multiplicative bucket (1) → multiplier ×= val; additive bucket (2) → additive += val; vitae bucket (8) → multiplier ×= val (applied last, matching retail `CEnchantmentRegistry::EnchantAttribute` semantics). 5 new EnchantmentMath StatMod-aware tests cover: multiplicative buffs aggregate, additive buffs sum, stat-key mismatch is filtered out, vitae applies multiplicatively, family-stacking picks the higher spell-id buff.

`ParseMagicUpdateEnchantment` (the live-update opcode 0x02C2) is **not** yet extended — it still uses the 4-field summary. That's a separate refactor; PlayerDescription's enchantment block is the load-bearing path for issue #6, and that's now flowing.

---

## #6 — [DONE 2026-04-25 architecture; data flowing as of #12] Vital max ignores enchantment buffs + vitae

**Closed:** 2026-04-25
**Commit:** `feat(player): #6 fold enchantment buffs into vital max via EnchantmentMath`
**Resolution:** Ported `CEnchantmentRegistry::EnchantAttribute` (PDB `0x00594570`) as `EnchantmentMath.GetMod(IEnumerable<ActiveEnchantmentRecord>, SpellTable, statKey)` returning `(Multiplier, Additive)`. Family-stacking dedup via `SpellTable.Family` (only one buff per family bucket wins, by highest spell-id as a generation proxy). `Spellbook.GetVitalMod(statKey)` delegates. `LocalPlayerState.GetMaxApprox` reworked to apply `(unbuffed × mult) + add` with retail's min-vital clamp (`>= 5` if base ≥ 5 else `>= 1`, matches `CreatureVital::GetMaxValue` at PDB `0x0058F2DD`). Stat-key constants (`MaxHealth=1`, `MaxStamina=3`, `MaxMana=5`) verified against `docs/research/named-retail/acclient.h` line 37287-37301.

**Architecture in place; data still flat.** Until ISSUES.md #12 lands the wire-format extension that captures `StatMod (type/key/val)` on `ActiveEnchantmentRecord`, the per-enchantment modifier value isn't aggregated yet — `EnchantmentMath.GetMod` returns `Identity (1.0, 0.0)` for every stat key. Once #12 wires the data, the existing aggregator + formula light up automatically. Live `+Acdream` Stam/Mana percent will continue to read ~95% until #12 lands.

6 new EnchantmentMathTests cover: empty list returns Identity, no-table-entries returns Identity, stat-key constants match ACE enum, Identity is `(1, 0)`, family-stacking dedup, family=0 (no-bucket) treated as separate.

## #11 — [DONE 2026-04-25] Spell metadata loader (spells.csv → SpellTable)

**Closed:** 2026-04-25
**Commit:** `feat(spells): #11 SpellTable — hydrate metadata from spells.csv at startup`
**Resolution:** Added `SpellMetadata` record + `SpellTable` CSV loader (hand-rolled RFC 4180-ish parser for the quoted Description column with embedded commas). Wired into `Spellbook` constructor as optional metadata source; `Spellbook.TryGetMetadata(spellId, out)` returns the static record when found. `GameWindow` loads `data/spells.csv` from bin output at construction (file copied via `<None Include>` in `AcDream.App.csproj` from `docs/research/data/spells.csv`). Falls back to `SpellTable.Empty` + console warning if the file is missing (e.g. tooling contexts). 10 new tests covering: empty table, header-only, simple row, quoted description with commas, blank lines skipped, bad spell-id rows skipped, lookup hit/miss, RFC 4180 escaped-quote parsing.

---

## #9 — [DONE 2026-04-25] Address-correction sweep on `acclient_function_map.md`

**Closed:** 2026-04-25
**Commit:** `docs(research): #9 sweep acclient_function_map.md against PDB symbols`
**Resolution:** Wrote `tools/pdb-extract/check_function_map.py` that cross-checks 63 hand-curated entries against `docs/research/named-retail/symbols.json`. Findings: **zero entries matched address-and-name exactly** (confirms ~0x800-0xC10 byte delta vs the binary that produced our Ghidra chunks — different build revision). 38 entries corrected by PDB name lookup; 25 entries either lack PDB symbol records (inlined / non-public) or had wrong class assignments (e.g. `0x5387C0` claimed as `CTransition::find_collisions` was actually `CPolygon::polygon_hits_sphere`). Updated `acclient_function_map.md` with corrected addresses, kept legacy addresses in a "Was" column for traceability, added a top-of-file sweep summary.

---

## #10 — [DONE 2026-04-25] Wire `KillerNotification (0x01AD)`

**Closed:** 2026-04-25
**Commit:** `docs(issues): #8/#9/#11 filed; #10 wired (KillerNotification)`
**Resolution:** Orphan parser at `GameEvents.ParseKillerNotification` existed but was never registered for dispatch in `GameEventWiring.cs`. Added a `combat.OnKillerNotification(victimName, victimGuid)` method on `CombatState` that fires a new `KillLanded` event, then registered the handler. One-line dispatch + 12-line CombatState method + one regression test fixture in `GameEventWiringTests`.

---

## #8 — [DONE 2026-04-25] pdb-extract tool: PDB → symbols.json + types.json

**Closed:** 2026-04-25
**Commit:** `tools(pdb-extract): #8 PDB -> symbols.json + types.json sidecar`
**Resolution:** Pure-Python (no deps) MSF 7.00 PDB parser at `tools/pdb-extract/pdb_extract.py`. Reads `refs/acclient.pdb` (Sept 2013 EoR build), extracts S_PUB32 records from the symbol stream + named class/struct types from TPI, and writes JSON sidecars to `docs/research/named-retail/`:
- `symbols.json` — 18,366 named functions (`address` + demangled `name` + raw `mangled`)
- `types.json` — 5,371 named class/struct records (`name` + `size` + `kind`)

Best-effort MSVC C++ demangler handles the common `?Method@Class@@<sig>` patterns + ctors (`??0`) + dtors (`??1`); operator overloads and vtables left mangled. Spot-check verified: `CEnchantmentRegistry::EnchantAttribute` resolves to `0x00594570` exactly as the discovery agent reported. Runtime <1s.

Regen workflow: `py tools/pdb-extract/pdb_extract.py refs/acclient.pdb`. The committed JSON outputs are stable + ~3 MB combined; ripgrep/jq on them is faster than re-parsing.

## #5 — [DONE 2026-04-25] VitalsPanel stamina/mana bars always null

**Closed:** 2026-04-25
**Commit:** `feat(player): #5 PlayerDescription parser — Stam/Mana via attribute block`
**Resolution:** First attempt (commit `d42bf57`) used `AppraiseInfoParser` for `PlayerDescription (0x0013)` — wrong wire format. ACE source confirmed via `GameEventPlayerDescription.WriteEventBody`: PlayerDescription is hand-written (DescriptionPropertyFlag-driven property hashtables, vector flags, attribute block, skills, spells, options/inventory tail) — distinct from `IdentifyObjectResponse (0x00C9)`'s `AppraiseInfo.Write`. Pivoted to a real port: new `PlayerDescriptionParser.cs` that walks property hashtables (Int32/Int64/Bool/Double/String/Did/Iid + Position) gated on the property flags, then reads vector flags + has_health + the attribute block where vitals 7/8/9 carry `ranks/start/xp/current`. Also redesigned `LocalPlayerState` to track per-vital snapshots (replacing the sentinel-API of attempt 1) plus per-attribute snapshots, with `GetMaxApprox` applying the retail formula `vital.(ranks+start) + attribute_contribution` (Endurance/2 for Health, Endurance for Stamina, Self for Mana). Live verified: `+Acdream` shows three bars; ~95% reading on Stam/Mana traced to active buff multipliers (filed as #6). Wire-port also added `PrivateUpdateVital (0x02E7)` + `PrivateUpdateVitalCurrent (0x02E9)` for delta updates per holtburger `UpdateVital`. ~700 LOC C#, 30+ new tests.

## #0 — [DONE 2026-04-24 · 593b76f] Sky cube edges visible as cross in daytime sky

**Closed:** 2026-04-24
**Commit:** `593b76f sky(phase-8.1): CLAUDE_TO_EDGE on static sky meshes`
**Resolution:** Switched to `GL_CLAMP_TO_EDGE` wrap mode for static sky
meshes; scrolling cloud layers kept `GL_REPEAT`. The 5 dome walls were
sampling opposite-edge pixels via UV wrap + LINEAR filtering, producing
visible seam lines that formed a cube outline across the view.
