[0.7.3] - 2026-08-27

Performance - 0.7.3

• Single GetItemInfo Fetch Per Item Tooltip:
  • Item tooltips previously called GetItemInfo once for the ilvl line, again inside TT_GS:GetItemScore, and a third time inside TT_GS:GetItemHunterScore on every hover of every equippable item.
  • Added TT_GS:GetItemScoreFromInfo(info) which scores from an already-fetched GetItemInfo result table; the item tooltip hook now performs exactly one fetch shared by ilvl, GearScore and HunterScore.
  • TT_GS:GetItemScore(link) and TT_GS:GetItemHunterScore(link, info?) remain fully backward compatible for frame overlays and other callers.
• Memoized ItemMixin Allocation in LibClassicInspector:
  • GetInventoryItemMixin allocated a fresh ItemMixin per slot per call (~19 allocations on every player hover from GearScore + Pawn scoring loops).
  • Mixins are now memoized per cached user and slot, keyed by item identity so a gear change in the same slot rebuilds its mixin instead of returning stale data. Entries die with their cache user on FIFO eviction.
• Overlay Offset Clamping:
  • Typed offset edit boxes now clamp keyboard-entered values to the ±300 slider range (setOffsetValue), so a typo cannot push an overlay permanently offscreen.
  • SafeSanitizeConfig repairs out-of-range or corrupt saved offsets (including "corrupt" strings, NaN and ±infinity) back to defaults on every load.

Fixed - 0.7.3

• Options OnShow Lifecycle (order-dependent overwrite):
  • Page builders no longer assign panel:SetScript("OnShow"); the load-tail safeCall-wrapped handlers own that slot and already invoke panel:Refresh(). Assigning inside the builder silently replaced them after first build.
• Library Hardening (LibClassicInspector):
  • GetTalentInfoByClass returns nil past a tab's real talent count instead of raising "attempt to index a nil value"; the same guard was applied to both the player and inspected-unit branches of GetTalentInfo.
  • The event dispatcher logs-and-continues via geterrorhandler() when a registered event has no matching handler method, keeping the frame alive instead of erroring on first fire.
  • Achievement validity probes use Blizzard's documented 14th isStatistic return instead of the undocumented 15th return that classic clients do not provide.
  • addCacheUser now returns the created user table so first-use callers (e.g. GetInventoryItemMixin) never operate on a nil cache entry.

Documentation & Testing - 0.7.3

• Accurate Backdrop Comments: Corrected stale "pre-2.5.3" notes across main.lua and memory bank — NineSlice-equipped tooltips are verified present on all supported clients (Classic Era, TBC Anniversary, Wrath); backdrop handling is runtime-detected via tooltip.NineSlice, not build-gated.
• New Regression Tests: Added SanitizeOffsetBounds (offset repair incl. NaN/infinity) and GetItemScoreFromInfoMatchesLink (single-fetch path produces identical scoring to the link path) WoWUnit tests — run with /tttest.
• Version metadata bumped to 0.7.3 across TacoTip.toc, main.lua, options.lua, README.md, CHANGELOG.md, AGENTS.md, and memory bank.
