feat(spell): count set bonuses in GetSpellBonusHealing

Set-bonus spells are applied server-side as auras the client never sees
as buffs or known spells, so the derived healing sum missed them —
Lawbringer (3) is "Increase Healing 31" (9317), Judgement (3) is 57
(18037). Add a pass that counts the equipped members of each set from
the item record's set id (OFF_ITEMSTATS_ITEM_SET), reads ItemSet.dbc's
bonus spells and member thresholds, and runs every met bonus through
the same aura decoder — the rule the item tooltip's set-bonus lines use
at 0x52DFB9.

The Ironclad (aura 199) armor conversion stays on
UNIT_FIELD_RESISTANCES[0]: the server's SpellBaseHealingBonusDone uses
GetArmor(), the full total, even though the talent text says "Armor
from items".

--- ClassicAPI's own entry in the AddOn Options window

--- Where retail's Settings shows a setting, the option copies its label,
--- tooltip and value mapping (Blizzard_SettingsDefinitions_Frame: Controls,
--- Combat, Accessibility; the TTS options use the Text To Speech window's
--- labels). Retail has no labels for the player cache, the cast settings or
--- friendly soft targeting, so those strings are ClassicAPI's own.

--- Changes apply at once. Cancel (and Escape) restores what each page held

---   - 1.12 has no taint or Secure-Templates system, so the entire
---     AttributeDelegate/SetForbidden machinery for inserting event keys
---     into the callback tables is unnecessary. Sub-tables are allocated
---     lazily inside RegisterCallback instead.
---   - securecallfunction/secureexecuterange don't exist; they reduce to
---     direct calls / explicit for-loops here.
---   - EnumUtil.MakeEnum is inlined as a plain string table.
---   - GenerateClosure doesn't exist in 1.12; provide a local one that
---     captures registration-time varargs via SafePack-style storage.
---   - Lua 5.0 has no select() or `wipe()`; we use the implicit `arg`

--- Backport of 3.3.5 FrameXML/ItemUtil.lua to vanilla 1.12 / Lua 5.0.

---     ClassicAPI.dll. We shim the missing ones at the top using the
---     stock 1.12 globals (GetItemInfo, GetInventoryItemLink,
---     GetContainerItemLink/Info). DLL-provided functions are left alone
---     via `or` guards so we never clobber a real implementation.

---     return values instead.
---   - CallErrorHandler isn't in 1.12; we route through geterrorhandler().
---   - In 1.12 OnEvent scripts, event name + payload are exposed via the
---     `event`, `arg1`, `arg2`... globals rather than as function args.
---   - 1.12 has no concept of an item GUID and no public item-lock API,
---     so those return nil / no-op.

---
--- Implementation differences from the modern source:
---   - 1.12 has no taint/secure system, so the entire Secure*/Proxy
---     machinery (SecureTypes, ProxyUtil, securecallfunction,
---     CreateForbiddenFrame) is dropped. Only the Unsecured pools and
---     pool collections exist; the canonical `CreateObjectPool` /
---     `CreateFramePool` / etc. globals are aliased to them at the
---     bottom of the file.
---   - FrameUtil.SpecializeFrameWithMixins isn't a thing in 1.12; the
---     "table specialization" branch is inlined as a plain Mixin().
---   - CreateMaskTexture and CreateActor aren't in 1.12 — the
---     corresponding pool creators are kept as stubs so chunk-load of
---     consumer addons doesn't fail; they'll error at Acquire() time

---   - Lua 5.0 has no select() and no `...` outside a vararg function

---   - 1.12 has no global wipe(); we ship a local Wipe() helper instead.

-This utility creates and returns a table of elements that are sorted by value "priority".
-
-Arguments:
-comparator - comparator(A, B) returns whether A has higher priority than B
-isAssociative - whether the table should be associative (true) or array-like (false). Only values have priorities for associative tables, not keys.
-
-Return usage:
-t[k]/t:Get(k)  - returns the value stored with key/index k
-t[k] = v       - (Associative only) stores the value v at key k, sorting accordingly
-t:Insert(v)    - (Array-like only) inserts the value v, sorting accordingly
-t:Remove(k)    - removes the element at key/index k
-t:Iterate(cb)  - calls function cb on each key/index value pair in sorted priority order
-t:GetTop()     - returns the highest priority element
-t:Pop()        - returns and removes the highest priority element
-t:GetBottom()  - returns the lowest priority element
-t:Size()       - returns the number of stored elements
-t:Clear()      - removes all elements

--- AoE Loot Test

--- with whatever's left.
---

--- succession, so the Blizzard LootFrame flickers during the scan. This

--- TableInspector.lua
---
--- Vanilla 1.12 backport of the modern Blizzard_TableInspector UX,
--- scoped to the "minimal" feature set: one navigable window with a
--- breadcrumb showing the current path, a scrollable list of (key,
--- value) rows for the current table, and click-to-drill / Back-to-pop
--- navigation through sub-tables.
---
--- Trade-offs vs the modern source:
---   * No DataProvider / ScrollBox infrastructure — we use the same
---     fixed-row + slider pattern EventTraceFrame uses (vanilla
---     FauxScrollFrame works too but we already validated the slider
---     approach in this addon).
---   * No anchor / attribute providers, no live polling — open once
---     against the current snapshot.
---   * No multi-tab or pinning — one window, navigate via Back.
---
--- API:
---   TableInspector_Show(tbl, label)   -- open with `tbl` as root, `label` shown in breadcrumb
---   TableInspector_Push(tbl, label)   -- drill in (called by row click)
---   TableInspector_Back()             -- pop one level
---   TableInspector_Refresh()          -- re-read the current level's live table (scroll kept)
---   TableInspector_Close()            -- hide the window
---   /tinspect <luaexpr>               -- evaluate `<luaexpr>` as Lua and open if result is a table

 existing addons benefit without any code changes. The complete per-function
 reference is in **[docs/API.md](docs/API.md)**.
 
-### Lua 5.1 compatibility
-
-The flagship feature: run modern Lua 5.1 addon code on 1.12's Lua 5.0 VM.
-
-| Feature | Effect |
-|---------|--------|
-| [Syntax](docs/API.md#lua-51-syntax) | Compiles the Lua 5.1 length (`#`), modulo (`%`), `...`-expression, `0x` hex-literal, and leveled long bracket (`[=[ ]=]`) syntax that vanilla's Lua 5.0 rejects, by rewriting addon source before it compiles. Each addon file also receives its `(name, table)` through `...` (`local name, tbl = ...`). |
-| [Upvalue limit](docs/API.md#upvalue-limit) | A function can use up to 60 upvalues, the outer locals it refers to, matching Lua 5.1. Lua 5.0 stops at 32 and rejects the whole file, so a large handler that reads many file-level locals can be valid 5.1 and still fail to load here. Nothing changes for a function within 32. |
-| [`for` loop variables](docs/API.md#for-loop-variables-per-pass) | Each pass of a `for` loop has its own loop variables, as in Lua 5.1, so a function made in the loop keeps that pass's values. On Lua 5.0 every such function sees the loop's last value, which is `nil` for a `for ... in` loop. |
-| [String methods](docs/API.md#string-methods-supper-sformat) | Every string value accepts method calls — `("asd"):upper()`, `("%d gold"):format(n)`, `msg:match("^!(%w+)")` — resolving through the `string` table, the way Lua 5.1 works. Works on literals and variables, in-world and on the login screen, and inside coroutines. |
-| [Script-handler arguments](docs/API.md#setmodernscriptargsenable--getmodernscriptargs) | Frame-script handlers receive their values as positional arguments — `OnMouseWheel(self, delta)`, `OnClick(self, button, down)`, `OnEnter(self, motion)`, `OnEvent(self, event, ...)`, etc. — so modern addon ports work unmodified. The `this` / `arg1` globals stay set. A handler that declares no parameters is unaffected. A frame method that you give directly as a handler gets `self`, so `f:SetScript("OnDragStart", f.StartMoving)` works. A handler that declared a parameter and expected nil now receives its real value. On by default. `SetModernScriptArgs(false)` restores exact vanilla dispatch. |
-| [XML script bodies](docs/API.md#xml-script-bodies-see-self-and-their-arguments) | An XML script body written for later clients, such as `<OnLoad>self:Init()</OnLoad>`, sees `self` and its script's arguments by name (`elapsed`, `button`, ...). Bodies that read `this` / `arg1` compile as before. |
-
-### Modern client behaviors
-
 | Feature | Effect |
 |---------|--------|
+| Lua 5.1 code | Addon code written for Lua 5.1 runs on the 1.12 Lua 5.0 VM. It covers the [5.1 syntax](docs/API.md#lua-51-syntax) (`#`, `%`, `...` expressions, `0x` hex, `[=[ ]=]` long brackets), [method calls on strings](docs/API.md#string-methods-supper-sformat) (`msg:match("^!(%w+)")`), [up to 60 upvalues](docs/API.md#upvalue-limit) for each function, and [new `for` loop variables](docs/API.md#for-loop-variables-per-pass) on each pass. Each addon file also gets its `(name, table)` through `...`. |
+| [Modern script handlers](docs/API.md#setmodernscriptargsenable--getmodernscriptargs) | Frame scripts get their values as arguments, for example `OnClick(self, button, down)` and `OnEvent(self, event, ...)`. [XML script bodies](docs/API.md#xml-script-bodies-see-self-and-their-arguments) such as `<OnLoad>self:Init()</OnLoad>` see `self` and their arguments by name. The `this` / `arg1` globals stay set. `SetModernScriptArgs(false)` restores the vanilla behavior. |
 | Inline textures | Draws inline texture markup (`\|T…\|t`) and atlas markup (`\|A…\|a`) as icons in FontStrings, chat, and tooltips. This covers item and spell icons, raid-target markers, and the coin icons in money strings. `GetStringWidth` and `GetStringHeight` count the icons, so measured width and text wrapping stay correct. Done in pure C++ by hooking the engine's text pipeline — no addon. |
-| [Soft targeting](docs/API.md#soft-interact-softinteract--anyinteract) | The Interact Key, and soft targets for enemies and friendly units. After you bind **Interact With Target** to a key, the key interacts with the nearest object in front of you. The object can be an NPC with a service, a corpse to loot or skin, a mailbox, a chest, or an herb or mining node. The [`softenemy` and `softfriend`](docs/API.md#soft-enemy-and-soft-friend-softenemy--softfriend--anyenemy--anyfriend) unit tokens point at the nearest enemy and the nearest friendly unit, and your target does not change. With no target, an attack or a harmful spell goes to `softenemy`, and a helpful spell goes to `softfriend`. Addons and macros use the picked units through the `softinteract`, `softenemy` and `softfriend` tokens. `anyenemy` and `anyfriend` use your target first. `PLAYER_SOFT_INTERACT_CHANGED`, `PLAYER_SOFT_ENEMY_CHANGED` and `PLAYER_SOFT_FRIEND_CHANGED` fire when the units change. The `SoftTargetEnemy` and `SoftTargetFriend` CVars turn on soft enemy and soft friend. The `SoftTargetIcon*` CVars show an icon over each unit. |
+| [Soft targeting](docs/API.md#soft-interact-softinteract--anyinteract) | The Interact Key and soft targets. Bind **Interact With Target** to a key to interact with the nearest NPC, corpse, mailbox, chest or gathering node in front of you. The [`softenemy` and `softfriend`](docs/API.md#soft-enemy-and-soft-friend-softenemy--softfriend--anyenemy--anyfriend) tokens point at the nearest enemy and friendly unit without a change of target. With no target, harmful spells go to `softenemy` and helpful spells go to `softfriend`. `PLAYER_SOFT_*_CHANGED` events fire when the units change. |
 | [Animations](docs/API.md#animation) | Animation groups on frames, textures and font strings, made in Lua or XML: `CreateAnimationGroup`, looping, smoothing, scripts and templates, with `Alpha`, `Translation`, `Scale`, `Rotation` and `Path` applied. |
 | Tooltip line cap | Removes `GameTooltip`'s 30-line limit for every `GameTooltipTemplate` frame (`GameTooltip`, `ShoppingTooltip1/2`, `ItemRefTooltip`, AtlasLoot, …). A tooltip adds a new line pair when it needs one, so long tooltips and comparison blocks (for example, pfUI's eqcompare) keep all their lines. |
-| [XML attributes](docs/API.md#parentkey-in-xml) | More XML attributes work: `parentKey="Name"` makes `parent.Name` point to a frame, texture or font string, `<OnLoad function="Name"/>` uses a global function as a script handler, `<OnLoad method="Name"/>` uses the frame's own function, `mixin="A, B"` copies mixins onto the object, `<KeyValues>` sets fields on the object, a button's `<NormalFont style="..."/>` sets its font, and `inherits="A, B"` applies more than one template. |
+| [XML attributes](docs/API.md#parentkey-in-xml) | More XML attributes work: `parentKey="Name"` makes `parent.Name` point to a frame, texture or font string, `<OnLoad function="Name"/>` uses a global function as a script handler, `<OnLoad method="Name"/>` uses the frame's own function, `mixin="A, B"` copies mixins onto the object, `<KeyValues>` sets fields on the object, a button's `<NormalFont style="..."/>` sets its font, and `inherits="A, B"` applies more than one template. `parentArray="Name"` adds the object to a list on its parent. An `<Anchor>` takes `x` and `y` offsets and `relativeKey="$parent.Key"`. `<OnEnter inherit="prepend">` runs the template's handler and then its own, and `inherit="append"` runs them in the other order. A frame with `intrinsic="true"` makes a new frame type. Frames take `scale`, `registerForDrag`, `clipChildren`, `useParentLevel`, `dontSavePosition`, `propagateKeyboardInput`, `propagateMouseInput`, `enableMouseClicks`, `enableMouseMotion` and `motionScriptsWhileDisabled`, and buttons take `registerForClicks`. Textures take `alpha`, `atlas`, `useAtlasSize`, `mask`, `desaturated`, `rotation`, `horizTile`, `vertTile`, `hWrapMode` and `vWrapMode`. Font strings take `alpha`, `wordwrap`, `indented`, `degrees` and `radians`. Status bars take `reverseFill`, `rotatesTexture` and `fillStyle`, and edit boxes take `countInvisibleLetters`. |
 | [Macro conditions](docs/API.md#more-commands-with-conditions) | `[conditions]` and `@unit` work on 38 slash commands, from `/cast` and `/use` to `/target`, `/follow`, `/cancelaura` and the `/pet` family. With `/cast [@mouseover,harm][] Fireball`, the spell goes to the mouseover unit. With no mouseover unit, it goes to your target. `@cursor` places a ground-target spell or item under the mouse and `@player` places it at your feet. A character name works where a unit token does (`[target=Feral]`). Addons read the same rules through `SecureCmdOptionParse`. |
-| [`#showtooltip`](docs/API.md#showtooltip-and-show) | A macro button shows what the macro does. The icon, tooltip, cooldown, range, usable state and auto-repeat glow all follow the spell or item that the directive resolves to, conditions included. They update as the conditions change. The result goes into the engine field that action-bar addons already read, so they need no code of their own. An addon with its own macro parser can publish its result through `C_Macro.SetMacroDisplay`. It then does not need to replace the action globals. |
+| [`#showtooltip`](docs/API.md#showtooltip-and-show) | A macro button shows the spell or item that its directive resolves to, conditions included: icon, tooltip, cooldown, range, usable state and auto-repeat glow. Action-bar addons get this with no code of their own. Addons with their own macro parser can publish through `C_Macro.SetMacroDisplay`. |
 | [Event-driven nameplates](docs/API.md#nameplate) | The modern `C_NamePlate` API, driven by real events. `NAME_PLATE_UNIT_ADDED` / `NAME_PLATE_UNIT_REMOVED` fire as plates appear and vanish, `nameplate1`..`nameplateN` tokens resolve with every `UnitX` function (and fire `UNIT_HEALTH`, `UNIT_AURA`, … as `arg1 == "nameplateN"`), and `C_NamePlate.GetNamePlateForUnit` / `GetNamePlates` hand back the live frames. |
 | [Focus target](docs/API.md#focus) | A sticky focus unit. `FocusUnit("target")` pins it and `ClearFocus()` drops it, with `PLAYER_FOCUS_CHANGED` on every change. The `focus` / `focustarget` tokens resolve with every `UnitX` function and fire unit events (`UNIT_HEALTH`, `UNIT_AURA`, … as `arg1 == "focus"`), and the predefined `FOCUSTARGET` / `TARGETFOCUS` keybinds are ready to set. |
-| [Combat log events](docs/API.md#combat_log_event_unfiltered--combat_log_event-events) | `COMBAT_LOG_EVENT_UNFILTERED` fires for each combat log event: a hit, a miss, a heal, a cast, an aura that starts or ends, a dispel, a death. Its values identify units by GUID and `COMBATLOG_OBJECT_*` flags. The values do not depend on the client language. As a result, damage meters and combat addons do not need to parse chat text. `CombatLogGetCurrentEventInfo` returns the same values. `COMBAT_LOG_EVENT` fires only for the events that match the `CombatLogAddFilter` filters. Addons can read recent events again as kept entries. The combat lines in the chat frames do not change. |
+| [Combat log events](docs/API.md#combat_log_event_unfiltered--combat_log_event-events) | `COMBAT_LOG_EVENT_UNFILTERED` and `CombatLogGetCurrentEventInfo` give each combat event with GUIDs and `COMBATLOG_OBJECT_*` flags. The values do not depend on the client language, so damage meters do not need to parse chat text. `COMBAT_LOG_EVENT` fires for the events that pass the `CombatLogAddFilter` filters. |
 | [Retail-like `/reload`](docs/API.md#reload-picks-up-new-addons-and-new-files) | `/reload` picks up addon changes made while the game runs. A new folder under `Interface\AddOns\` registers and loads as a normal addon, new files added to an existing addon's TOC load, a newly installed addon's first SavedVariables save survives `/reload`, `##` metadata edits (`## SavedVariables:`, `## Dependencies:`, `## Title:`, …) take effect, and a deleted addon folder drops from the addon list. |
 | [Multi-flavor & conditional TOC](docs/API.md#conditional-and-multi-flavor-toc-loading) | Loads modern multi-flavor addons that ship one folder. Selects a version-specific TOC (`<Name>_ClassicAPI.toc` or `<Name>_Turtle.toc`) and the matching keybinding file (`Bindings_ClassicAPI.xml` / `Bindings_Turtle.xml`), accepts a comma-separated `## Interface:` version list (compatible when it includes the client version `11200`), and honors per-line `[AllowLoadGameType]` / `[AllowLoadTextLocale]` conditions and `[Family]` / `[Game]` / `[TextLocale]` path variables inside a TOC. |
 | [Launch switches](docs/API.md#launch) | Options you add to the shortcut that starts the game. `-config <name>` reads and writes `WTF\<name>` in place of `WTF\Config.wtf`, so one install can hold several settings profiles. `-gluescript` and `-gluescriptFile` run Lua at the login and character-select screens, every time those screens appear. `-gamescript` and `-gamescriptFile` run it one time, after you enter the world. Each script runs after the interface has loaded, so it can call interface functions and use frames. |

-## Bundled addon: DebugTools
+## Lua errors
 
-A 1.12.1 / Lua 5.0 backport of Blizzard's `Blizzard_DebugTools` addon
-lives in [`AddOns/DebugTools/`](AddOns/DebugTools/).
-It's an independent addon — it doesn't use anything ClassicAPI adds, and
-ClassicAPI works fine without it. It's bundled here because it's the
-natural companion for testing and debugging anything written against the
-1.12 Lua surface (with or without the ClassicAPI extensions).
+ClassicAPI replaces the game's Lua error box with a Lua error window. The
+window opens when an error occurs. It shows the message, the time, the count,
+the stack and the local variables of each error. You can select and copy the
+text. The arrow buttons show the previous and the next error. The
+**Reload UI** button reloads the interface.
 
-Slash commands provided:
+If you use `!BugGrabber` (with BugSack), BugGrabber gets the errors and the
+window does not open. If an addon sets its own error handler, the window also
+does not open.
 
 | Command | Purpose |
 |---------|---------|
-| `/dump <expr>` | Pretty-print any Lua value, including tables and multi-return tuples. The right tool for inspecting return values from `GetSpellInfo`, `C_Item.GetItemInfoInstant`, etc. |
-| `/etrace` | Event tracer window. `/etrace start`, `/etrace stop`, `/etrace add EVENT`, etc. |
-| `/framestack` (or `/fstack`) | Tooltip showing the frame hierarchy under the mouse cursor. |
-| `/luaerrors` (or `/scripterrors`) | Lua error display window. |
+| `/luaerrors` (or `/scripterrors`) | Opens or closes the Lua error window. |
+| `/luaerrors clear` | Removes all errors from the window. |
 
-Lua globals provided (backports of Blizzard helpers):
+## Debug tools
 
-| Global | Purpose |
-|--------|---------|
-| `print(...)` | Backport of Blizzard's `print` — concats varargs with `" "` and pushes to `DEFAULT_CHAT_FRAME`. Routes through `setprinthandler`'s handler; falls back via `geterrorhandler` if the handler errors. |
-| `setprinthandler(func)` / `getprinthandler()` | Install / query a custom print handler. Useful for redirecting print output in tests. |
-| `tostringall(...)` | Apply `tostring()` to every vararg, preserving the count. Lua 5.0-compatible (uses `arg.n` since `select` doesn't exist in 5.0). |
+ClassicAPI contains backports of two Blizzard addons: `Blizzard_DebugTools`,
+with the name `ClassicAPI_DebugTools`, and `Blizzard_EventTrace`, with the
+name `ClassicAPI_EventTrace`. The DLL contains these addons, so you do not
+install them. They are not in the AddOns list, and you cannot disable them.
 
-To install: copy [`AddOns/DebugTools/`](AddOns/DebugTools/) into your
-`Interface/AddOns/` directory like any other addon.
+The slash commands are always available. Each addon loads the first time
+that you use one of its commands:
+
+| Command | Purpose |
+|---------|---------|
+| `/dump <expr>` | Shows a Lua value in the chat frame. It shows tables and all return values. Use it to examine the return values of `GetSpellInfo`, `C_Item.GetItemInfoInstant`, and other functions. |
+| `/etrace` (or `/eventtrace`) | Opens or closes the event trace window. The window logs each event with its time and its arguments. Move the mouse over an event to see its arguments, and the contents of each table argument. You can search the log, hide events with the filter, and pause the log. `/etrace mark <text>` adds a line of text to the log. |
+| `/framestack [showHidden [showRegions]]` (or `/fstack`) | Shows a tooltip with a list of the frames under the cursor. A `-->` mark shows one frame, with its anchors and the file and line that made it. Left Alt and Right Alt move the mark. Ctrl opens the marked frame in the table inspector. Shift shows its texture files. The tooltip also shows the addon that made the marked frame. When `scriptProfile` is `1`, it shows the CPU time of the frame scripts. |
+| `/tinspect [expr]` (or `/tins`) | Opens a table inspector on the result of `expr`. With no table, it opens on the frame under the cursor. The window shows the anchors and the fields of the table, grouped by type. You can edit numbers, strings and booleans, filter the lines, and open a child table or frame. |
+| `/profiler` (or `/prof`) | Opens the profiler. The profiler shows the Lua memory, the allocations and the CPU time of each addon, frame, event and global function. `/profiler widget` shows a small window with the Lua memory, the frame rate and the addons that use the most. `/profiler reset` sets the counters to zero. CPU times need `scriptProfile` `1`. `/profiler profile on` sets it and reloads the UI. |

-The original TODO note ("engine maintains a completed-quests bitfield in

-equivalent: neither `QueryQuestsCompleted` nor `GetQuestsCompleted`
-exists, the protocol has no `CMSG_QUERY_QUESTS_COMPLETED`, and the
-client doesn't track historical completions. The polyfill at
-`Util/C_QuestLog.lua:5-8` works on Frostmourne (3.3.5a) where those
-functions exist; on the 1.12 Octo client they're absent.
+Stock 1.12 has no completed-quests query and keeps no quest history, so
+this exists only where the server offers the list another way. Turtle WoW
+and its forks answer the player command `.queststatuses` with `TWQUEST`
+guild addon messages from the player, split at 2000 characters, the last
+message always shorter (probed: 2003, 2004, 0) - an exact end marker.
 
-Servers that want to expose this in 1.12 (notably Turtle WoW) do it
-via the `CHAT_MSG_ADDON` channel — the addon sends `.queststatus` over
-guild/whisper chat and the server replies with addon-channel messages
-the addon parses. Fundamentally async, server-specific, and requires
-SavedVariables-style persistence across sessions to amortize the
-round-trip — all of which belong on the Lua side, not in this DLL.
-There's nothing the DLL can usefully add here.
+[src/quest/Completed.cpp](src/quest/Completed.cpp) does it all in the DLL,
+Turtle clients only: it sends the request itself (on
+SMSG_LOGIN_VERIFY_WORLD, after each turn-in, and from

+must be the player), and keeps the live list behind `GetQuestsCompleted`,

-  synchronously; the icon regions are separate objects whose placement is only
-  known once the line builds mid-paint, after the frame's texture pass already

-  pre-render from the frame's own methods) forces each icon-bearing line to
-  resolve+build and applies its icon placement synchronously — before the frame
-  draws — so icons move in lockstep with their text. It reuses the engine's own
-  `Realize(0)` → `RebuildString` → ensure-built path and the same placement math
-  the paint flush uses (`ComputePlacementsForNode`), so the later flush dedups to
-  a no-op. Additive and best-effort: any line whose rect isn't resolvable in time
-  falls back to the paint + tick pipeline (correct, one-frame lagged). A pure
-  scroll or drag never lagged — the icons are anchored to the line and the engine
-  moves them for free; only content changes on a reused line needed this.
+- **Rendering** — 4.3.4's `CSimpleEmbeddedTexture` model. Each icon is a
+  pooled `CSimpleTexture` with no frame, anchored to its fontstring: it is in

+  (`FUN_FONTSTRING_EMIT` `0x00772E50`, 4.3.4's `CSimpleFontString::Draw` →
+  `QueueTextures`) adds the icons right after its text, and only when the text

+  screen, or scrolled off the top of a chat frame — in the same frame.
+- **No one-frame lag** — 4.3.4 sets the embedded textures up in `UpdateString`,

+  ensure-built call the paint makes) and applies the placements at once, so a
+  string's icons draw with its text wherever it was rebuilt (a chat line laid
+  out by its frame, a tooltip line, a rect change). The paint-pass co-hook

+// C_AutoComplete: the player names an edit box can complete.
+//
+// 4.3.4's CGAutoCompleteName keeps its own list of names, each with flag bits
+// that the party, raid, guild, friend list and chat code add and remove as
+// those lists change. 1.12 has no such list, but it keeps every list the bits
+// come from, so a query reads them where the engine keeps them:
+//   - party: the four VAR_PARTY_GUIDS, the name from the name cache, online
+//     from the member stats block (Group::MemberStats) - InGroup;
+//   - raid: the VAR_RAID_MEMBER_PTRS slots and their online bit - InGroup;
+//   - guild roster: each GuildMemberInfo's GUID, name and online word, read
+//     only while the player is in a guild, the test Script_IsInGuild
+//     (0x00516DE0) makes, because the engine keeps the old roster after a
+//     /gquit - InGuild;
+//   - friends list: the social singleton's slots (FriendList.h) - Friend.
+// The one list the engine does not keep is ours: the players this character
+// whispered or was whispered by (Chat::Dispatch reports each line), in the
+// order they were last heard from - InteractedWith. Logging out clears it,
+// as 4.3.4's ShutdownGame clears its list.
+//
+// A player on several lists is one entry with every list's bit. A list that
+// holds the player decides Online; a player known only from a whisper is
+// Online, as 4.3.4 sets Online together with InteractedWith.
+//
+// Matching is 4.3.4's NodeMatchesParams (the same in 3.3.5's binary,
+// 0x0057ACA0), with two differences:
+//   - a cursorPosition outside 1..length means the end of the text. Retail's
+//     tell-target extraction (ChatFrameEditBox.lua) passes 0 and expects a
+//     whole-text match;
+//   - the edit-from-center search also tries the last place. The engine's
+//     loop stops one place early, so it never finds the text after the
+//     cursor at the end of a name.
+// Order is 3.3.5's SortNameNode (0x0057B130): with
+// autoCompleteResortNamesOnRecency on, the most recent whisper first, then by
+// name. Retail's client cannot be read, so each result's priority is the
+// highest Enum.AutoCompletePriority its bits reach, in the enum's own order:
+// Friend, Guild, InGroup, Interacted, else Other.

+//     error function sets none, but while a handler runs that function's
+//     level is on the stack (ErrorCallstack::ErrorFunctionLevel).
+//   - `level` counts as lua_getstack and debugstack do: 1 is the caller.
+//     Less than 1 is 1.
+//   - A table prints as `name=<table>{`, or with the frame's name for a
+//     frame (t[0], as FrameScript_GetObject reads it), then its fields one
+//     space in at the top level only, then `}`. A function prints where it

+// A number key in int range prints truncated with %d, as 4.3.4's
+// IsIntegerNumber tests only the range: 2.5 prints as 2. Two departures from
+// 4.3.4, both where it would fail inside the handler: a number key outside
+// that range is formatted from a copy, not converted in place (that breaks
+// lua_next), and a key that is not a number or string prints as its type in
+// angle brackets (4.3.4 formats a null string).
+//
+// Retail also lists `(*temporary)` lines: 5.1's lua_getlocal names each stack
+// slot past a level's locals so, a C level's arguments included (an
+// `error("x")` report shows `(*temporary)="x"`). 1.12's lua_getlocal

+// failed, however many functions sit between that code and the handler:
+//     debugstack(GetCallstackHeight() - (GetErrorCallstackHeight() - 1))
+// A height counts call levels as lua_getstack does, and so as debugstack
+// does: C functions and lost tail calls count, and level 1 is the caller of

+//
+// 1.12 records no error height, and needs none. Every error report runs the
+// engine's error function (FUN_FRAMESCRIPT_CALL_ERROR_HANDLER) as a C
+// closure: each script pcall passes it as the errfunc, so Lua calls it at
+// the point of the error before the stack unwinds, and a chunk that fails
+// to compile is reported by a pcall of it (FUN_LUA_RUN_STRING). It calls the
+// seterrorhandler function with lua_call. So while any handler runs, that
+// closure's level is on the stack directly above the code that failed, and
+// GetErrorCallstackHeight answers the height below the innermost one.
+// Nothing is recorded, so a handler that fails part way leaves nothing

+// `string.gsub` takes 5.1's string and table replacements.
+//
+// 1.12's str_gsub (0x7FD0E0) is Lua 5.0's, and differs from 5.1 in its
+// replacement argument:
+//   - it takes a string or a function, not a table;
+//   - `%0` in a replacement string, and `%1` when the pattern has no
+//     captures, raise "invalid capture index" (5.1: the whole match);
+//   - a function that returns nil or false deletes the match (5.1 keeps it),
+//     and one that returns a table deletes it too (5.1 raises an error).
+//
+// The first two only ever raised errors, so 5.1's behavior cannot break a
+// 1.12 addon. The third does: SuperAPI's CombatText_AddMessage returns nil
+// to delete the player's own " [0x...]" GUID from heal text. A function
+// replacement therefore stays the engine's own add_s.
+//
+// str_gsub itself stays: its match loop, anchor, count and buffer are the
+// same in both. Two parts are replaced:
+//   - the argument gate (SITE_LUA_STR_GSUB_REPL_CHECK) becomes CheckReplacement;
+//   - the one add_s call (CALL_LUA_STR_GSUB_ADD_S) goes to AddValue: 5.1's
+//     add_s for a string or number, 5.1's table lookup for a table, and the
+//     engine's add_s for a function. They use the engine's capture helpers.

-// --- string.gsub table-replacement upgrade (Lua 5.1) ------------------------
-//
-// 5.1 allows a TABLE as gsub's replacement: each match looks up the first
-// capture (the whole match when the pattern declares no captures) in the
-// table; a nil/false value keeps the original match; string/number values
-// substitute. This engine's gsub (FUN_LUA_STR_GSUB) is stock 5.0 —
-// string/function only ("string or function expected" otherwise), and its
-// add_value appends NOTHING when a replacement function returns a
-// non-string (match → empty; verified by decode, see Offsets.h). So a
-// plain table→closure adapter would EAT unmatched tokens where 5.1 keeps
-// them, and the closure can't reconstruct the whole match from capture
-// args alone.
-//
-// The shim therefore rewrites the pattern with one OUTER capture —
-// `pat` → `(pat)`, keeping a leading `^` and an unescaped trailing `$`
-// outside (both are anchors only at their positional ends; inside the
-// parens they'd turn literal) — so the adapter closure always receives
-// the whole match as arg 1, the pattern's own first capture as arg 2, and
-// can hand arg 1 back to reproduce 5.1's keep-match for missing keys.
-// Patterns containing a `%1`..`%9` back-reference can't be wrapped (the
-// outer capture would renumber what `%N` refers to); those fall back to
-// an unwrapped adapter whose missing-key behavior is the engine's own
-// (match → empty) — the one documented divergence, and the combination
-// (table replacement + pattern back-references) is essentially absent
-// from real code. String/function replacements tail-call the engine gsub
-// untouched.
+// `string.byte(s [, i [, j]])` / `strbyte` — the codes of bytes i..j, as
+// 4.3.4's str_byte (j defaults to i). 1.12's (0x7FC210) is 5.0's: it reads
+// only `i` and pushes one code. With `j` absent the two give the same
+// result for every `i`. Positions truncate toward zero as the engine's
+// str_byte and str_sub do. The engine's lua_checkstack (0x6F2F30) refuses
+// more than 2048 stack slots, so the longest range is about 2000 bytes.

+//     teardown in CGGameUI::ShutdownGame, 0x00498700, clears the flag) stops
+//     both;
+//   - each time the flag turns on, a new file starts, named as retail names
+//     it: Logs\WoWCombatLog-MMDDYY_HHMMSS.txt, the local time logging started.
+//     1.12's own Logs\WoWCombatLog.txt keeps its chat-text lines, which 1.12
+//     log readers parse;
+//   - the file is a Storm log, opened as LoggingCombat opens its own (append)
+//     and written with SLogWrite (which stamps "M/D HH:MM:SS.mmm  " on each
+//     line, as in 4.3.4's file). When the flag turns off it is closed, which
+//     writes its buffered lines. Storm closes what is still open at exit;
+//   - the line is PackEvent's: no hideCaster, flags as hex, the spell school
+//     as a hex mask (the extra spell's in decimal), damage values as numbers,
+//     flags as 1 or nil, no isOffHand and no alternate power type.
+//
+// The flag is read once a frame (FrameTick, which also runs on the glue
+// screen, so a logout's cleared flag is seen there) and before each line.
+// LoggingCombat itself is not hooked: other DLLs add their own logs to it.

+// wow_turbo (github.com/athei/wow-mods) detours ~380 engine functions to Rust
+// reimplementations and yields any function another mod has already hooked:
+// its installer refuses a prologue that fails its signature. It installs from
+// DllMain, but ClassicAPI installs from `Load`, which VanillaFixes calls after
+// every DllMain, so wow_turbo never sees our hooks and always installs first.
+// MinHook then copies wow_turbo's jump into our trampoline, and our hook calls
+// the Rust body instead of the engine's. That loses everything that lives in
+// the stock body: Frame::ScriptArgs' pcall redirects in both script runners,
+// and InlineTexture / IndentedWordWrap in the text builder, whose Rust copy
+// calls its own emitter.
+//
+// `Reclaim` gives the stock prologue back before we hook, the state wow_turbo
+// itself produces when it loads after a mod that hooked first. wow_turbo keeps
+// its original in place, logs "prologue overwritten ... by ClassicAPI.dll"
+// and does not re-patch these entries.
+//
+// The DllMain core hooks need no reclaim: the only one wow_turbo also
+// replaces is the integrity scan, which both make the same no-op.
