[v1.13.5] (2026-08-05) - Offline test suite, and the ten defects it found

Bug Fixes

• The Interface Options "Defaults" button raised a Lua error and, had it not, would have done nothing. Interface.lua:GreenWallInterfaceFrame_SetDefaults calls gw.settings:reset() with no arguments, but GwSettings:reset(svtable, meta) required the settings table and indexed it immediately — so the first key it looked at raised attempt to index local 'svtable' (a nil value). Underneath that was a second defect that would have surfaced the moment the first was fixed: the body only assigned a default if svtable[k] == nil or self:validate(k, svtable[k]), i.e. only for keys that were absent or invalid. That guard is correct in initialize(), which fills gaps, and was copied into reset(), whose whole job is to overwrite values that are present and valid — making it a no-op on any real settings store. Now defaults svtable to the store for the current mode and assigns unconditionally, stamping updated. Location: Settings.lua:reset.
• Third-party addons that registered an API handler with '*' never received a single message. API.md documents '*' as "messages from all addons will be handled", but gw.APIDispatcher tested addon == e[2] or addon == '*' — asking whether the sending addon was literally named '*' rather than whether the registration was the wildcard. Both GreenWallAPI.SendMessage and AddMessageHandler assert addon == C_AddOns.GetAddOnInfo(addon), so no real sender can ever be named '*' and that clause was dead: every wildcard handler was registered, sorted, and never called. Now tests e[2] == '*'. Location: API.lua:APIDispatcher.
• A single mistyped version line in the Guild Information panel aborted the entire configuration parse for every member of the confederation. The GW:v: and GW:o:mv= handlers gated on strmatch(field[2], '^%d+%.%d+%.%d+%w*$'), which is looser than the vendored semantic-version parser accepts — that parser requires a - before a pre-release suffix. So GW:v:1.2.3beta passed the regex, semver() returned nothing at all, and tostring() with no argument raised, unwinding out of GwConfig:load() before the channel, peer and officer directives on the following lines were ever read. Validation is now done by parsing rather than by regex: an unparseable version is logged and skipped, and the rest of the page still loads. Location: Config.lua:load.
• GwConfig:is_container() raised on every call. It opened with if guild == self:GetGuildName(), but GwConfig has no such method — the helper is gw.GetGuildName() — so any call died with attempt to call method 'GetGuildName' (a nil value). Fixed, and the guild-tag test tightened to reject the empty string as well as nil, so a confederation whose GW:p: list omits the local guild is correctly reported as not configured rather than claiming membership on an empty tag. Location: Config.lua:is_container.
• The bridge channel was never hidden from the chat windows, and the code that tried would have raised if it had ever matched. Channel.lua:join scanned GetChatWindowMessages(i) looking for the bridge channel's name, but that API returns message group names (GUILD, SAY, SYSTEM) — the channel list is the separate GetChatWindowChannels(i), and Blizzard reads the two into RegisterForMessages and RegisterForChannels respectively. A group name can never equal a channel name, so the loop matched nothing and the hide step silently did nothing. Inside it, ChatFrame_RemoveChannel(frame, self.name) passed the frame's name string; since patch 1.15.9 that global is only a deprecation alias for ChatFrameMixin.RemoveChannel, which takes the frame as self, so a match would have raised on pairs(self.channelList). This is the fourth site broken by the same 1.15.9 refactor (after v1.13.2, v1.13.3 and v1.13.4) and the only one not reported by a player. Now scans the channel list with the correct stride and passes the frame object, over NUM_CHAT_WINDOWS rather than a hard-coded 10. Location: Channel.lua:join.
• Hold-down timers could stop firing silently, and leaked a frame on every start. GwHoldDown:start created its OnUpdate frame into a bare local that went out of scope the moment the method returned; nothing else referenced it, because the handler takes frame as a parameter rather than capturing it. Whether the timer survived therefore depended entirely on the client never reclaiming the frame — and when it does not fire there is no error, the callback simply never runs. Since refresh_channels restarts these timers for the whole session, the flip side was that every start created a new frame that is never released. The frame is now created once, kept on the instance, and reused. Found by the new suite, which fails deterministically under the coverage runner and passes without it. Location: HoldDown.lua:start.
• /gw logsize lots (and any non-numeric value for a numeric setting) threw a Lua error instead of printing the message explaining the mistake. gw.Error('%s setting must be numeric: %s', key) supplies two format specifiers and one argument, so string.format raised before the message could be written. Location: GreenWall.lua:GwSettingCmd.
• Three defects in the vendored semantic-version library, all in the pre-release comparison layer that had never executed offline. Found once the vendored Lib/ files were brought under test. (1) A version carrying build metadata but no pre-release was rejected outright — the suffix pattern required a leading -, so 1.0.0+20130313144700, which semver 2.0.0 section 10 explicitly permits, parsed to nothing and a GW:v: line using it was silently discarded. (2) The comparison was not antisymmetric: an alphanumeric-versus-numeric identifier returned "less than" in both directions, so 1.0.0-alpha < 1.0.0-1 and 1.0.0-1 < 1.0.0-alpha were both true and any ordering built on it depended on argument order. (3) A shorter pre-release outranked a longer one — running out of fields on the left returned "greater than", making 1.0.0-alpha rank above 1.0.0-alpha.1, the reverse of the specification's own worked example. The library is GreenWall's own (Copyright 2010-2020 Mark Rogaski) and its output never crosses the wire — the minimum-version check is evaluated independently by each client — so fixing it changes no peer-visible behaviour. VERSION_MINOR is bumped from 1 to 2, and that bump is load-bearing rather than bookkeeping: LibStub:NewLibrary returns nil when oldminor >= minor, so at an unchanged minor this corrected copy would lose to any other addon vendoring the same very generic SemanticVersion-1.0 major that happened to load first — the fixes would ship and never execute. At minor 2 GreenWall's copy upgrades an older one in place, on the same table, so references captured by whoever registered first pick up the corrected behaviour. Location: Lib/SemanticVersion.lua.

Changes

• gw.IsOfficer() no longer takes a target. Its documented target parameter had been silently ignored since the rank lookup was replaced by the GM-officer-note check (a workaround for 7.3.0 making GuildControlSetRank() protected). The rank-based helper it left behind was unreachable dead code and has been removed, along with the parameter — a signature that advertises a contract it does not honour is worse than none, and no caller passed one. Location: Utility.lua:IsOfficer.

Repo Tooling

• Added an offline test suite: 427 examples, 100% line coverage across all 13 addon files and the three vendored libraries GreenWall owns. Built on the shared WoWAPITesting harness, carried as a git submodule at Tests/wowapi. It needs nothing but a Lua 5.1 interpreter — no LuaRocks, no busted, no C modules — and runs in well under a second: lua Tests/wowapi/run.lua from the addon root, with lua Tests/wowapi/coverage.lua <files> gating coverage at 100%. Every one of the defects above was found by writing the spec for how the code should behave and then reading the failure. Nothing here ships: Tests is ignored by the packager.
• Removed the previous tests/ suite. The luaunit-based cases, the vendored luaunit.lua, MockAPI.lua, Loader.lua and run-tests.ps1 are gone, their coverage folded into the new specs. That suite needed the bitlib C module (and therefore a C toolchain) to run at all; the harness supplies bit in pure Lua. The upstream PR branches (pr/era-fixes-tests and friends, cut from upstream-*) keep their own copy and are unaffected.
• Fixed .pkgmeta, which was shipping the entire development tree to players. Every folder entry carried a trailing slash (docs/, tests/) and the script globs used **/ (**/*.ps1). The BigWigs packager trims a trailing /* and not a bare /, so docs/ became docs//* and matched nothing; its case-based glob matching has no recursive **, so those globs never matched either. Both folders and both script globs were therefore being packaged. Rewritten to bare folder names and single-star repo-relative globs, with the no-op dot-entries dropped — the packager prunes those unconditionally.
• Raised eight harness contracts and adopted the answers. Tests/HARNESS_CONTRACT.md records what GreenWall needed that the harness did not model: the chat-window subscription queries, the chat frames and their edit boxes, a steerable time(), the four missing ERR_GUILD_* strings, C_GuildInfo.GetInfoText, GetChannelDisplayInfo/GetChannelList, getglobal, and C_AddOns.GetAddOnInfo/IsAddOnLoaded. All eight were delivered upstream and the local stand-ins deleted; the submodule is pinned at 65de3af.
• Added the .busted shim, taught .luarc.json the spec globals, and normalised the test directory to Tests — it had been tracked as lowercase tests, which the case-sensitive Linux packager would not have matched against the .pkgmeta entry.

Notes

• No behaviour visible to players changed except the fixes above; the TOC, wire protocol and configuration grammar are untouched.
• Lib/ is now under test too, with one deliberate exception and one structural limit. Lib/LibStub.lua is the canonical public-domain stub and GreenWall's copy correctly stands down in favour of whichever identical copy registered first, so almost none of it is reachable in a suite — that is the file working as designed, not a gap. Lib/SemanticVersion.lua sits at 98.86%: the single remaining line is a cmp(nil, nil) guard that cannot be reached, since the loop that calls it never runs past the longer operand. Left in place rather than deleted to keep the diff minimal for the upstream offer.
• Lib/Base64BCA.lua is deliberately not changed. Its output is the only vendored library's that crosses the wire (a sender encodes an API payload and a peer decodes it), so a behavioural change there would break interop between GreenWall versions across a confederation. It is now covered at 100% and round-trips every byte value, so the encoding is pinned rather than merely assumed.

[v1.13.4] (2026-07-22) - Restore inbound bridging after the 1.15.9 chat-frame refactor

Bug Fixes

• Co-guild messages stopped displaying on the stock UI after patch 1.15.9, throwing Chat.lua:110: attempt to call a nil value on every inbound message. The same chat-frame refactor that broke outbound bridging in v1.13.3 also removed the global ChatFrame_MessageEventHandler outright — it is now a method on each chat frame (ChatFrameMixin:MessageEventHandler), with no deprecation-fallback shim. GreenWall bound that global once at load in Compat.lua and uses it in Chat.lua:ReplicateMessage to inject received peer messages into the chat windows, so on the default UI it captured nil and every decoded peer message errored instead of displaying. Inbound receipt and decoding still worked (the debug log showed opcode=C segments arriving from peers) — only the final display call failed. This is why the breakage looked partial in the field: GreenWall overrides that same binding with ElvUI's and Prat's own handlers (Compat.lua), which still exist, so ElvUI/Prat users' inbound kept working while stock-UI users saw nothing (matching the reported "only some people can see messages" pattern). Now feature-detects: uses the global ChatFrame_MessageEventHandler where it still exists, otherwise adapts to the frame method (frame:MessageEventHandler(...)); the ElvUI/Prat overrides are untouched. Location: Compat.lua.

Notes

• This completes the trio of WoW 1.15.9 (interface 11509) breakages, all stemming from the same client refactor of the chat frame and add-on APIs: v1.13.2 fixed the GetAddOnInfo login crash, v1.13.3 fixed outbound /g and /o bridging (the dead ChatEdit_ParseText hook), and this fixes inbound display of co-guild messages on the stock UI.

[v1.13.3] (2026-07-22) - Restore outbound bridging after the 1.15.9 chat-frame refactor

Bug Fixes

• Guild and officer chat stopped bridging outbound after WoW patch 1.15.9 — messages reached local guild chat but were never sent to co-guilds. 1.15.9 (interface 11509) rebuilt the chat edit box into the mixin-based Blizzard_ChatFrameBase system. GreenWall forwarded your outgoing /g and /o messages to the bridge via hooksecurefunc("ChatEdit_ParseText", ...), but in the new system the global ChatEdit_ParseText is only a deprecation-fallback alias (ChatEdit_ParseText = ChatFrameEditBoxMixin.ParseText) — the client now calls the edit box's own ParseText method, so the hook on the global never fired. The addon still loaded and the bridge channel still connected (inbound worked), which is why /gw status showed connected=true while nothing you typed ever crossed; a debug 5 capture confirmed the type=GUILD, message=... hook line was absent on send. Verified against the 1.15.9 UI source that the new ChatFrameEditBoxBaseMixin:ParseText(send, ...) still exposes GetAttribute("chatType") and the stripped message via GetText(), so GreenWall's handler body is unchanged — only the hook target was wrong. Now hooks each chat edit box instance's ParseText method where the mixin exists (if ChatFrame1EditBox and ChatFrame1EditBox.ParseText then ... hooksecurefunc(editbox, 'ParseText', ...) ... end), and falls back to the legacy global hook on older clients — so every supported flavor keeps working. This same refactor already shipped on Retail (11.0) and Mists Classic, where the global hook was likewise dead. Location: GreenWall.lua.

Changes

• Bumped the Classic Era TOC to interface 11509 for WoW 1.15.9. Only GreenWall.toc (Era) changed; the other five per-flavor TOCs keep their own interface versions. Location: GreenWall.toc.

Notes

• This is the second half of the 1.15.9 breakage. v1.13.2 fixed the GetAddOnInfo login crash that the same patch introduced; this release fixes the separate, quieter outbound-bridging regression from the chat-frame refactor. Inbound replication (peer messages arriving in your guild window) was unaffected — it flows through CHAT_MSG_CHANNEL / ChatFrame_MessageEventHandler, not the edit-box hook.

Repo Tooling

• Added ChatFrame1EditBox to the .luarc.json known-globals list so the new feature-detect reads clean under the Lua language server.

[v1.13.2] (2026-07-22) - Fix GetAddOnInfo nil-call crash and migrate deprecated chat/guild globals

Bug Fixes

• GreenWallAPI crashed with attempt to call a nil value whenever a third-party addon touched the API — a WoW client update removed the loose global GetAddOnInfo, which now exists only as C_AddOns.GetAddOnInfo (confirmed in the generated AddOnsDocumentation under Namespace = "C_AddOns", with no deprecation-fallback shim, so the bare global is simply nil). Unlike the softer guild/chat deprecations below, this one is a hard removal: any caller reaching GreenWallAPI.SendMessage / AddMessageHandler / ClearMessageHandlers for a non-'*' addon id hit assert(addon == GetAddOnInfo(addon)) and threw immediately — observed in the wild as VersionCheck-1.0 calling AddMessageHandler at login. The rest of the addon had already migrated to the C_AddOns namespace in v1.12.0 (Globals.lua, Compat.lua); API.lua was the one file missed. Replaced all three call sites with C_AddOns.GetAddOnInfo. Location: API.lua.

Changes

• Proactively migrated two now-deprecated globals off the client deprecation-fallback path. The same client update that removed GetAddOnInfo also demoted GetGuildInfoText and SendChatMessage to deprecated shims that live in Blizzard_DeprecatedGuildScript / Blizzard_DeprecatedChatInfo — they are now thin aliases for C_GuildInfo.GetInfoText and C_ChatInfo.SendChatMessage, load only when the loadDeprecationFallbacks CVar is set, and are documented in-client as "will be removed in the future." GreenWall still worked because that CVar defaults on, but the fork should not depend on a fallback that can be switched off or dropped in a later patch. Migrated both using the same feature-detect-with-fallback idiom v1.13.1 introduced for C_GuildInfo.GuildRoster: if C_GuildInfo and C_GuildInfo.GetInfoText then ... else GetGuildInfoText() end in Config.lua:load, and if C_ChatInfo and C_ChatInfo.SendChatMessage then ... else SendChatMessage(...) end in Channel.lua:tl_flush. The namespaced call is used wherever it exists (Era 1.15.x and every other current flavor) and the original global is preserved as the fallback, so no flavor regresses. The namespaced C_ChatInfo.SendChatMessage is the same restricted function as the global — this is a rename, not a taint/protection change — so the wire protocol and CRC-16 loopback accounting are unaffected. Locations: Config.lua, Channel.lua.

Notes

• Full audit of the addon's WoW API surface against the updated Classic Era docs. Every loose global the addon calls was cross-checked against the generated API docs, the GlobalAPI.lua enumeration, and the Blizzard_Deprecated* shim files. Results: GetAddOnInfo was the only hard removal (fixed above); GetGuildInfoText and SendChatMessage were the only two deprecations (migrated above). Everything else the addon uses is still a first-class global with no namespaced-only replacement — GetChannelName, JoinTemporaryChannel, LeaveChannelByName, GetChannelList, GetChatWindowMessages (Channel.lua / Chat.lua / GreenWall.lua); GetGuildInfo, GetNumGuildMembers, GetGuildRosterInfo (Utility.lua); GetRealmName, UnitName, GetBuildInfo (Globals.lua / Utility.lua / SystemEventHandler.lua); and GetCVar (a real global defined in Blizzard_SharedXMLBase/CvarUtil.lua, GreenWall.lua). No further changes were required.
• This supersedes the v1.13.0 note that listed GetGuildInfoText and SendChatMessage as "verified portable" loose globals — that was accurate when written, before Blizzard moved them behind the deprecation-fallback CVar.

Repo Tooling

• Added TestConfigInfoText regression coverage for the new guild-info-text source selection, mirroring the existing TestConfigReload cases: verifies GwConfig:load() prefers C_GuildInfo.GetInfoText when present, and falls back to the GetGuildInfoText global both when C_GuildInfo is absent and when the table exists but lacks the method. Updated TestAPI's setUp to stub C_AddOns.GetAddOnInfo instead of the removed global. Full offline harness green (60 cases). Locations: tests/TestConfig.lua, tests/TestAPI.lua.

[v1.13.1] (2026-05-19) - Fix GuildRoster() nil-call crash on non-Era flavors

Bug Fixes

• GuildRoster() crashed on TBC Classic / Wrath / Cata / Mists / Retail with attempt to call global 'GuildRoster' (a nil value) — v1.13.0 added per-flavor TOCs but did not audit the Lua source for API calls that were Era-only. Blizzard moved GuildRoster() into the C_GuildInfo namespace years ago (it remains as a loose global only on Classic Era 1.15.x); on every other flavor the global is nil, so GwConfig:reload() threw on the very first config load and the addon was unable to bootstrap its bridge configuration. Replaced the bare GuildRoster() call with if C_GuildInfo and C_GuildInfo.GuildRoster then C_GuildInfo.GuildRoster() else GuildRoster() end — modern API on flavors that have it, original global preserved for Era so existing 1.15.x users see no behavior change. Reported on TBC/Anniversary. Location: Config.lua:reload.

Repo Tooling

• Refreshed CLAUDE.md to match post-v1.12.0 / post-v1.13.0 reality. The "Changelog rules" section described the legacy ## X.Y.Z -- YYYY-MM-DD / ### Fixed format, but the project switched to the togpm format (## [vX.Y.Z] (YYYY-MM-DD) - Title headers with prose-rich ### Bug Fixes / ### New Features / ### Changes / ### Notes / ### Lint Pass / ### Repo Tooling sections) in v1.12.0; updated the rules to document the togpm format. Added a new TOC rules section: TOCs now use the GreenWall-v1.13.5 packager substitution token (no manual ## Version: bump), there is no ## X-Date: line, and there are 6 flavor-specific TOC files to keep in sync — the previous CLAUDE.md still instructed bumping ## Version: and ## X-Date: in a single GreenWall.toc, neither of which exists anymore.
• Fixed three pre-existing markdownlint errors in CLAUDE.md so the file lints clean under the project's .markdownlint.json config. (1) Saved-variables and GW: directive tables used the compact alignment-row style (|---|---|---|) while their data rows used padded pipes — mismatched style flagged as MD060/table-column-style. Normalized both alignment rows to padded style (| --- | --- | --- |). (2) The GreenWallMeta row contained an unescaped | inside a code span (mode = 'account' | 'character') which MD056/table-column-count parsed as an extra column separator. Escaped the pipe to \|. (3) The wire-segment example fence had no language hint — flagged as MD040/fenced-code-language. Tagged it as text.

[v1.13.0] (2026-04-30) - Multi-flavor support: per-flavor builds for Classic Era, BCC, Wrath, Cata, Mists, and Retail

GreenWall has been Classic-Era-only since the fork started, by virtue of a single-flavor TOC. The Lua source itself was already portable — every API the addon touches has been present on Retail and the intermediate Classic flavors for years. This release is the packaging change that lets the BigWigs packager produce a build per flavor from one source tree.

New Features

• Per-flavor TOC files added. The CurseForge / BigWigs packager auto-detects flavor-suffixed TOCs and builds one zip per flavor on every tagged release. The unsuffixed GreenWall.toc remains the Classic Era 1.15.x build (Interface 11508). New siblings:

  • GreenWall_TBC.toc — Burning Crusade Classic / Anniversary 2.5.x (Interface 20505)
  • GreenWall_Wrath.toc — Wrath Classic 3.4.x (Interface 30405)
  • GreenWall_Cata.toc — Cataclysm Classic 4.4.x (Interface 40402)
  • GreenWall_Mists.toc — Mists Classic 5.5.x (Interface 50503)
  • GreenWall_Mainline.toc — Retail 11.x (Interface 110207)

  All TOC bodies are byte-for-byte identical except for ## Interface: and ## X-Min-Interface:. The packager workflow at .github/workflows/release.yml is unchanged and picks them up automatically.

Notes

• No Lua source changes. Surfaces verified portable across all supported flavors: Settings.RegisterCanvasLayoutCategory / Settings.RegisterAddOnCategory (GreenWall.lua), C_AddOns.GetAddOnMetadata (Globals.lua), C_AddOns.IsAddOnLoaded (Compat.lua), C_ChatInfo.RegisterAddonMessagePrefix (GreenWall.lua), the channel API surface (JoinTemporaryChannel, LeaveChannelByName, GetChannelName, GetChannelDisplayInfo, SendChatMessage/'CHANNEL', ChatFrame_RemoveChannel, Channel.lua/Utility.lua), the localized ERR_* constants used by SystemEventHandler.lua, GetGuildInfoText and the rest of the guild-roster API used by Config.lua and Utility.lua, and the hooksecurefunc("ChatEdit_ParseText", ...) outbound hook in GreenWall.lua. Defensive compat shims (Settings.* or InterfaceOptions_AddCategory, C_AddOns or _G) were considered and skipped — there is no live flavor where any of these is absent.
• Transport is unchanged and works on every flavor. The custom-chat-channel transport (JoinTemporaryChannel + SendChatMessage(..., 'CHANNEL', ...)) carries across connected-realm clusters on every flavor of WoW. Guild membership is itself bounded to a cluster, so no cross-cluster transport rework was needed for Retail.

[v1.12.0] (2026-04-29) - First Pimptasty fork release: long-standing bug fixes, dead-code cleanup, modernized TOC

This is the first release of the Pimptasty fork. Mark Rogaski's original work covers releases 0.9.00 (2010-11-01) through 1.11.18 (2025-05-24); see LICENSE for full attribution.

Bug Fixes

• Roster announcements duplicating for every co-guild member crossing the bridge channel — GwHoldDownCache:hold had an inverted comparison since v1.5.3 (2014-11-11): if self.cache[s] > t + self.interval then rv = true is structurally never true (a stored timestamp can't be greater than a later timestamp plus an interval), so the comember-cache that was supposed to dedupe online/offline announcements always returned false. Every member of every co-guild logging in produced two notifications: one from the natural CHAT_MSG_SYSTEM event (ERR_FRIEND_ONLINE_SS), and one generated by GreenWall's CHAT_MSG_CHANNEL_JOIN handler. The cache's pruning logic was also broken: #self.cache > self.soft_max always evaluates 0 because the cache is hash-keyed by player name, and table.remove(self.cache, k) is the wrong API for a string key. Replaced the comparison with t - self.cache[s] < self.interval, the length check with a pairs() enumeration, and the deletion with self.cache[k] = nil. Location: HoldDown.lua:GwHoldDownCache:hold.

• Stale channels not cleared after Guild Information edits — GwConfig:load()'s cleanup loop used for _, channel in ipairs(self.channel) do over self.channel = { guild = ..., officer = ... }. ipairs only iterates contiguous numeric keys starting at 1, so the loop body never ran. When officers edited Guild Information to remove a channel directive, the addon would keep transmitting on the now-orphaned channel until the player ran /gw reset or relogged. Switched to pairs. Location: Config.lua:load.

• GreenWallAPI.RemoveMessageHandler was broken since the API was introduced in v1.7.0 — the function had three bugs in its 14 lines: rv = false was a leaked global; the if addon ~= '*' then addon = GetAddOnInfo(addon); assert(addon ~= nil) end block referenced addon, which is not a parameter of this function (it was copy-pasted from ClearMessageHandlers); and gw.api_table[i] = nil left a hole that stopped subsequent ipairs walks at the gap. Any third-party caller using the documented API hit undefined behavior on every call. Rewrote to match the documented contract and switched to table.remove. Location: API.lua:RemoveMessageHandler.

• gw.IsLegendary leaked _ and rarity globals on every call — _, _, rarity = GetItemInfo(item) had no local declaration. Function was an orphan from the legendary-loot-replication feature removed in v1.11.0 (Blizzard made SendChatMessage partially protected in patch 8.2.5, killing the feature). Deleted gw.IsLegendary and gw.GetItemString. Also deleted other v1.11.0 orphans missed at the time: GwPromoteSystemEventHandler (never dispatched by the factory), the rank field destructured from GW_MTYPE_BROADCAST payloads in gw.handlerGuildChat, and an unused local semver = LibStub:GetLibrary(...) import. Locations: Utility.lua, SystemEventHandler.lua, Chat.lua.

• Invalid Lua 5.1 escape sequence in the gw.Debug call-stack parser — the pattern string 'in function \`([%a_-]+)\'' used a backslash followed by a backtick, which is not a valid escape sequence per the Lua 5.1 spec (only \a \b \f \n \r \t \v \\ \" \' \[ \] \xxx are recognized). WoW's interpreter accepted it (treating unknown escapes as the literal char), but lua-language-server flagged it as an error-severity diagnostic. Replaced with a literal backtick — runtime behavior unchanged. Location: Utility.lua:gw.Debug.

• Malformed 'id=%, addon=%s, priority=%d' debug format string in two gw.Debug calls in API.lua — %, is not a valid format specifier; string.format would error if the message was ever logged at debug level 4+ (GW_LOG_INFO for the add API handler / remove API handler messages). Replaced with %s. Location: API.lua.

• GreenWallAPI.ClearMessageHandlers left holes when removing multiple matching handlers — gw.api_table[i] = nil while iterating with ipairs causes the iterator to stop at the first nil. If two handlers for the same addon were registered, only the first one would be cleared. Switched to reverse-iteration with table.remove so deletions properly compact the array. Location: API.lua:ClearMessageHandlers.

• Redundant self:initialize_param(true) argument in GwConfig:reset() — the method takes no parameters; the true was silently ignored. Cosmetic but flagged as a redundant-parameter warning by lua-language-server. Location: Config.lua:reset.

Lint Pass

• Cleaned trailing whitespace, dead local declarations, and unused loop variables (_ substitution) across Config.lua, Utility.lua, Channel.lua, and Chat.lua. All Lua source files now lint clean under the bundled .luarc.json configuration.

Changes

• Updated TOC for WoW Classic 1.15.8 (Interface 11508).
• Modernized the TOC. Switched ## Version to the CurseForge packager substitution token GreenWall-v1.13.5. Replaced legacy ## X-Category: Guild with the modern ## Category: Guild. Added ## X-Min-Interface: 11508, ## OptionalDeps: ElvUI, Prat-3.0, Identity-2, Name2Chat, Incognito (one per chat-addon GreenWall has compat shims for in Compat.lua), ## X-License: MIT, and ## X-Curse-Project-ID. Dropped ## DefaultState: enabled (default behavior anyway), ## X-Date: 2025-05-24 (CHANGELOG is the source of truth), and the two ## URL: lines (now declared via X-Curse-Project-ID and .pkgmeta). Location: GreenWall.toc.
• Future changelog entries use the togpm format — ## [vX.Y.Z] (YYYY-MM-DD) - Short Title headers, prose-rich Bug Fixes / New Features / Changes / Improvements sections, root-cause + symptom + fix structure, file-link locations. Older entries (v1.11.18 and below) keep their original format.

Repo Tooling

• Filled in LICENSE. It was the unfilled MIT template (Copyright (c) <year> <copyright holders>) since the project began. Mark Rogaski credited for 2010-2025 (releases 0.9.00 through 1.11.18); Pimptasty credited for 2026+ modifications. The MIT license body is unchanged.
• Added CLAUDE.md — architectural guidance for working in the codebase: file load order, GwChannel / GwConfig / GwSettings class roles, the GW: configuration-directive grammar, the hidden-channel wire protocol with CRC-16 loopback detection, the public GreenWallAPI surface, and the changelog/commit conventions used by this fork.
• Added docs/curseforge_description.html — CurseForge listing copy, the source of truth for the project's listing page. Updated on every release alongside the changelog.
• Added repo configs: .pkgmeta (CurseForge packager), .luarc.json (lua-language-server config tuned to GreenWall's API surface), .markdownlint.json, .markdownlintignore.
• Author line in GreenWall.toc now reads Mark Rogaski <stigg@aie-guild.org>, Pimptasty.
