Changelog

0.8.1 - 2026-08-16

• Stop a taunt or aggro rip from briefly reading as a deep deficit. The client can flip isTanking up to one threat push before the percentage pair refreshes, and the stale sub-100 rawPercentage inferred a phantom contender at playerThreat / (stale% / 100) — a deficit that grew with the player's own fresh threat. A sub-100 percentage while tanking now joins the exactly-100 self-reference branch, so the badge reads the lead over the exact observable contenders instead.
• Keep every verified inference behavior unchanged: tanking percentages above 100 still infer the second-place reference, the tanking 255 sentinel stays suppressed, non-tanking readings (including sub-100 and the fixate 255 case) are untouched, and an exact observable leader still produces a real deficit while tanking.
• Add pure-math boundary coverage and a mocked-runtime aggro-flip regression for the stale tuple.

0.8.0 - 2026-07-31

• Add an enabled-by-default Smooth number transitions setting that eases same-sign live counter changes over 180 milliseconds while keeping the exact threat target unchanged.
• Snap sign changes, newly shown or recycled plates, configurator/test samples, and safety colors immediately so animation never obscures a current semantic state.
• Advance all active transitions from one reusable 30 Hz list on the existing scheduler frame, without additional frames, threat queries, or per-refresh persistent tables.
• Keep the General transition toggle independent from Reset Appearance while including it in Revert and Reset All, and avoid layout or style work for behavior-only changes.
• Add database, configurator, lifecycle, query-isolation, sign-change, toggle, and simultaneous 40-nameplate regression coverage for the new behavior.

0.7.2 - 2026-07-31

• Treat the verified TBC Anniversary 2.5.6 tanking rawPercentage=255 value as an unusable self-reference sentinel, preventing a sole player from acquiring a phantom contender at 1/2.55 of the player's threat.
• Retain exact queryable contenders and non-tanking percentage inference, including a potentially meaningful non-tanking 255% value during forced-target mechanics.
• Add pure-math and mocked-runtime regression coverage for the captured true, 3, 100, 255, 116421 client tuple.

0.7.1 - 2026-07-31

• Split role detection, nameplate presentation, threat scheduling/lifecycle, and client probes into focused runtime modules with explicit internal interfaces.
• Split the configurator's preview mechanics, controls, and window integration so each module owns one frame-lifecycle boundary without changing saved settings or user behavior.
• Load the mocked runtime from the TOC during tests, keeping shipped-file order in one manifest.

0.7.0 - 2026-07-31

• Report an exact tie with an unqueryable reference actor as +0 instead of the player's entire threat total. The raw percentage is now only treated as self-referential while the player is actually tanking, removing a discontinuity where 99.999999%, 100%, and 100.000001% produced -1, +5k, and +1.
• Read the nameplate unit token from unitToken, the field Blizzard's NamePlateBaseMixin:SetUnit actually writes, before the legacy namePlateUnitToken and UnitFrame.unit fallbacks.
• Keep /threatplating test from permanently re-enabling a disabled addon: the sample now flips the runtime flag only and restores the saved disabled state when the eight seconds expire.
• Print usage for unknown subcommands instead of silently toggling the configurator, so a typo can no longer close the editor.
• Stop a resize-grip press with no movement from ratcheting the saved minimum badge width up by the current text width on every touch.
• Keep the periodic editor refresh from overwriting a slider's edit box while it has keyboard focus, and restore an abandoned partial entry when focus is lost.
• End an open color-picker session before Reset Layout, Reset Appearance, Reset All, and Revert replace the color tables, so a later cancel cannot resurrect a discarded color.
• Disable the preview badge's hit box while it sits outside its canvas, and raise every footer button above it, so a badge placed at an extreme offset cannot swallow their clicks.
• Clear an in-flight preview drag when the editor is hidden mid-drag, which previously froze the passive baseline refresh until the next completed drag.
• Clear every mirrored text key between baseline reads, so a plate with no readable name is no longer drawn with the previous plate's font, offset, and color.
• Fail closed when the shapeshift API returns a non-numeric spell ID rather than silently grading bear druids and defensive-stance warriors as non-tanks.
• Refuse to install over the checkout itself, which previously deleted the working tree and its history when the checkout lived at the documented Interface\AddOns\ThreatPlating path.
• Validate the TOC manifest and load order, pin the toolchain to Lua 5.1, declare read-only Blizzard APIs as read-only, and route tank-role precedence through a single implementation.
• Add /threatplating probe, which prints the raw return tuples of every client API whose slot layout the addon depends on next to the addon's reading of each, so a client patch that shifts a slot is diagnosable immediately instead of appearing as inverted raid colors.
• Add tools\link.ps1 to deploy the checkout as a junction for fast iteration, and document that it cannot coexist with the publishing guarantee that only pushed commits reach the client.
• Make ThreatPlating.toc the single source of truth for the shipped file set: check.ps1 and install.ps1 both derive their lists from it, install.ps1 reads the manifest belonging to the revision it installs, and validation now fails if a root Lua file is missing from the TOC or a test suite on disk is never run.
• Teach the test mock the client's frame-template rules, so a backdrop call without BackdropTemplate or a misspelled template name fails locally instead of in game.
• Add a deterministic 600-step editor interaction fuzz pass covering the interleavings that produced four of this release's bugs, asserting after every step that no interaction can persist a setting startup validation would rewrite and that live color-picker edits reach the current database.

0.6.3 - 2026-07-31

• Preserve exact raw-threat ordering below one displayed threat unit, so a real contender lead can no longer be hidden by the former comparison tolerance while compact formatting remains unchanged.
• Fail closed when legacy talent or shapeshift APIs return malformed numeric values, and extend the raid suite across early add events, queued recycling, sustained event pressure, party/pet source topology, restricted recovery, and scheduler-state bounds.
• Normalize saved configurator window offsets and expand automated coverage across all saved settings, display controls, preview fallbacks, session restores, and independent close paths.
• Lint every Lua test, enforce synchronized client/source metadata, validate clean main before publishing, and make local installation stage-verified and rollback-capable.

0.6.2 - 2026-07-31

• Reduce the independent nameplate reconciliation fallback from 0.20 to 0.10 seconds so missed threat events and pooled-frame changes recover sooner during ordinary combat.
• Retain the five-plate per-frame scheduler cap, so the faster cadence increases update frequency without increasing the maximum amount of exact threat work performed in one frame.

0.6.1 - 2026-07-31

• Resolve threat events that identify the player or another threat actor back to that actor's current hostile target, instead of dropping them and waiting for the 0.20-second fallback poll.
• Keep direct hostile-unit events targeted, deduplicate actor/hostile aliases through the urgent queue, and retain the five-plate per-frame query budget.

0.6.0 - 2026-07-31

• Fix raid deficits by scanning every existing group member, group pet, player pet, and non-duplicate enemy target before using the API percentage to account for an unqueryable reference actor.
• Decouple color from the sign: tanks are green while actually tanking and red after losing aggro; non-tanks are green below the pull threshold and red while tanking or at/above it. Orange still overrides both roles inside the scaled pull-threshold warning bracket.
• Validate every required threat tuple, accept the API's valid nil-threat result as zero, and hide safely on restricted, malformed, or meaningless data.
• Resolve roles through main-tank and explicit assignments, form/stance rules, Blizzard's guarded effective-tank helper, and legacy talent trees in that order.
• Stagger exact work through reusable urgent and poll queues, deduplicate overlapping requests, verify pooled ownership when dequeuing, and cap processing at five complete plates per frame.
• Hide configurator samples immediately on close, then queue restoration of real threat values.
• Add a deterministic 25-player, 25-pet, 40-nameplate raid suite covering exact third-actor deficits, sign-independent safety colors, pets, aliases, roster changes, restrictions, recycling, event priority/coalescing, the 255-query frame budget, and stable scheduler/frame counts.

0.5.1 - 2026-07-30

• Preserve one database table identity through ADDON_LOADED, adopt the client's final SavedVariables table into it, and point ThreatPlatingDB back to the table held by the editor.
• Fix 0.5 settings reverting on /reload because the editor could mutate a startup table other than the global table serialized by WoW.
• Add runtime coverage for late SavedVariables replacement, legacy adoption, and subsequent editor mutations reaching the serialized global.

0.5.0 - 2026-07-30

• Replace the fixed configurator with a responsive Blizzard-native editor that reflows between side-by-side and stacked layouts from 520 × 520 through 1000 × 800.
• Derive the preview baseline from the current visible target nameplate when available, including its health texture/color/fill, dimensions, unit-name text, health text, fonts, colors, and text placement; follow target changes while the editor remains open.
• Add a pinned live preview, tank/non-tank and safe/danger/warning scenarios, nine health-bar anchor presets, exact numeric entry, independent badge and font sizing, and a scrollable controls pane.
• Add stock Blizzard font presets, text shadow, configurable padding, background RGB/opacity, semantic/custom/off borders, three built-in threat palettes, and fully custom semantic colors.
• Add versioned saved-variable migration and independent validation for every boolean, enum, numeric range, color component, collapsed section, and editor geometry field.
• Add Reset Layout, Reset Appearance, Reset All, Revert, and Done actions. Ordinary closing keeps live changes; Revert restores the display and enabled-state snapshot captured when the editor opened.
• Keep Options → AddOns lightweight with a synchronized enable control, detected-role summary, and Open Editor action.
• Coalesce continuous layout and style changes to 20 real-overlay restyles per second, commit final interaction values immediately, and avoid additional threat queries during styling.
• Track ownership of Blizzard's shared color picker and clean up only Threat Plating's active session.
• Preserve the 0.4.1 pooled-nameplate, targeted-refresh, restricted-query, and allocation reliability work.

0.4.1 - 2026-07-30

• Detach an existing NPC overlay immediately when Blizzard reassigns its pooled nameplate to a player or player-controlled unit, rather than waiting for the fallback reconciliation poll.
• Refresh only the affected visible plate after nameplate-specific threat events while retaining the independent 0.20-second correctness fallback.
• Eliminate per-scan contender-list allocation, reuse pooled overlay records and hide hooks, and skip unchanged text, width, and color assignments.
• Treat any truthy Classic main-tank assignment result as an explicit tank signal.
• Add adversarial runtime coverage for restricted threat queries, direct eligible-to-ineligible plate recycling, targeted refresh query counts, and unchanged render-state caching.

0.4.0 - 2026-07-30

• Show an orange warning when the player has surpassed the enemy's current target in raw threat but remains below the aggro pull threshold.
• Use the API's scaled threat percentage so the warning automatically respects the 110% melee and 130% ranged-distance thresholds without class or range guessing.
• Keep the signed raw-threat lead or deficit unchanged while orange temporarily overrides the tank/non-tank role color.
• Add /threatplating test orange for visual validation.

0.3.0 - 2026-07-30

• Detect tank intent from explicit group assignments, Protection talents, warrior Defensive Stance, and druid Bear or Dire Bear Form.
• Keep threat signs unchanged while making colors role-aware: green marks the desired threat state and red marks the dangerous state for the detected role.
• Refresh role colors immediately after role, talent, roster, and shapeshift changes.
• Show the detected tank or non-tank color mode in the configurator and status command.

0.2.2 - 2026-07-29

• Keep the 0.20-second fallback scan independent from event refreshes so sustained threat events cannot starve nameplate reconciliation.
• Verify every overlay against the API's current unit-to-nameplate mapping and clean up missed removal events or recycled plates.
• Stop nameplate scans and threat queries while the addon is disabled.
• Preserve raw-threat semantics during taunts and fixates by using valid reference percentages even while the player has aggro.
• Reject non-finite saved settings and threat values, keep the restored badge tall enough for its font, and improve compact rounding at sub-unit, 1k, and 1m boundaries.
• Clarify both the fallback poll and minimum event-refresh interval in /threatplating status.
• Expand mocked lifecycle coverage for event cadence, pooled frames, missed removals, disabled mode, and invalid saved variables.

0.2.1 - 2026-07-29

• Prevent the draggable preview badge from overlapping configurator controls.
• Raise the title and footer close buttons above editor content.
• Add Escape and /threatplating close as independent recovery paths.

0.2.0 - 2026-07-29

• Add a movable and resizable visual configurator opened by /threatplating.
• Add a draggable and resizable badge preview anchored to a 2.5.6 nameplate health-bar mock.
• Apply layout changes live to currently visible real nameplates.
• Persist anchor, offsets, dimensions, font size, background, automatic width, enabled state, and configurator placement.
• Register an Options → AddOns category and AddOn Compartment action.
• Add anchor presets, reset behavior, and configurator testing guidance.

0.1.0 - 2026-07-29

• Add signed threat lead/deficit badges to visible enemy NPC nameplates.
• Add group, pet, current-target, and raw-percentage threat resolution.
• Add event-driven refresh with a 0.20-second polling fallback.
• Add a temporary visual test command.
• Add Lua 5.1 tests, lint configuration, and in-game validation guidance.
