hide_archive_links is only honored by Gitea on release edit, not create —
add the PATCH step after create/lookup so auto-generated source archive
links actually stay hidden (coa-template 90874c5).
WoW 3.3.5 Lua 5.1 runtime has table.setn as an error stub ("'setn' is obsolete")
and table.getn missing/erroring. The embedded Ace2 libs (AceLibrary, AceOO, AceEvent,
AceConsole, AceDebug, AceDB, Tablet-2.0) all assign table_setn = table.setn at module
scope when GetBuildInfo() does not start with "2." — causing AceOO-2.0 to crash at
line 546 before any library can register, then cascading to AceConsole/FuBarPlugin.
Add Lua50Compat.lua as the first TOC entry to unconditionally overwrite table.setn
(no-op) and table.getn (returns #t) before any lib loads. Also shims
table.foreach/foreachi in case future libs need them. Verified with LuaJIT 5.1:
AceLibrary + AceOO load cleanly; all other libs stop only at WoW-API boundaries
(not at obsolete-call errors).
Walk testers through cloning into a folder named VanillaGuide (the
.toc filename, not the repo name) under Interface/AddOns/, and ask
them to install BugSack + !BugGrabber so any Lua errors come back as
copy-pasteable stacks instead of vibes.
GuideTable.lua:88 used the Lua 5.0 global getn() to size the color-
substitution table opentext. In Lua 5.1 (WoW 3.3.5) the bare getn is
gone and table.getn is deprecated, so this would have crashed with
'attempt to call global getn (a nil value)' before any guide could
render. Replaced with the # length operator.
Also record the fix and the upstream README cleanup under 'Files we
touched' in README-CoA.md.
