+## 2026-09-14 New-character PC bars and missing-spell borders
+
+- A temporary browser fixture used the real desktop bars, ability controls,
+  spellbook, combat store, and character UI activation with memory-only saves.
+  Fresh Priest and Mage profiles populated their PC bars automatically. The
+  Mage started with Frostbolt, Fire Blast, Frost Nova, and Arcane Intellect.
+- Clearing Lesser Heal gave its spellbook entry and ability-picker entry a
+  visible light blue border, including the icon border. Both computed border
+  colors were `rgb(146, 213, 255)`. Assigned and locked spells kept their usual
+  borders. Reassigning Lesser Heal removed the missing-spell border.
+- Switching to the fresh Mage and back retained the Priest's cleared slot.
+  Screenshots of both missing-spell menus were inspected during the playtest.
+  The temporary fixture was removed afterward.
+- Validation: 62 focused tests, TypeScript, production build including bundle
+  verification, and the release-candidate check passed. Full-game verification
+  was limited by a persistent opening-expedition loading screen in both local
+  development and production; menu visuals were verified in the fixture.
+
+## 2026-09-14 Ability hover tooltips
+
+- Entered Stormwind Stockade with the existing offline level-17 Priest through
+  the normal roster, dungeon, and role screens. Hovering Smite on the controller
+  bar displayed its description, Mana cost, cast time, cooldown, range, and
+  target. Leaving the button removed the tooltip.
+- Opened Ability controls and its ability picker. Hovering Shadow Word: Pain
+  displayed its own description without assigning it. Flash Heal was readable
+  by hover and keyboard focus despite its level-20 lock. Switching from keyboard
+  inspection to another hovered ability left exactly one tooltip visible.
+- Checked the picker at the default 650 x 490 viewport and at 1280 x 800.
+  Tooltip DOM bounds remained inside the viewport. The in-app screenshot
+  scales unusually with a viewport override; reset the override afterward.
+- Enabled desktop bars in an unsaved UI-layout draft. Hovering the leftmost
+  Smite button showed the tooltip above the bar, clamped to the left edge and
+  outside the HUD's transformed layout container. Discarded the layout draft.
+- A temporary Flash Heal assignment during input testing was restored to the
+  original Smite assignment. No character or template was created or deleted.
+- Screenshot evidence: `playtest-artifacts/ability-tooltips/desktop-bar.png`
+  and `playtest-artifacts/ability-tooltips/locked-picker.png`.
+- Automated verification: all 64 UI tests passed, including nine tooltip
+  content, unavailable-control, and viewport-placement regression tests.
+  TypeScript, the production build, and the release candidate check passed.

+
+## Account-wide boss card collections — 2026-09-14
+
+- Moved boss card counts and reward receipts out of character profiles into one
+  collection per account owner. Gameplay starts with that account collection;
+  menu and in-game collection screens show the same account totals.
+- Migrates existing character logs by summing their rarity counts, retaining the
+  newest reward receipts, and removing the old character fields. Reloading or
+  downloading an old cloud roster again does not repeat the migration.
+- Cloud uploads now include the account collection, including accounts with an
+  empty roster. Migrated cloud logs upload without waiting for another boss kill.
+  Higher cached counts and newer receipts survive an older cloud download.
+- Automated integration checks verified earning on a second character,
+  switching back, account sign-out isolation, character deletion, and restoration
+  into a separate device cache. Collection markup identifies the account scope.
+- Validation: 164 tests passed across 19 files, with six shelved-mode tests
+  skipped. This persistence change did not alter character models or equipment.
+- TypeScript, prebuild asset audits, and release hygiene passed. The first
+  shared-output bundle check encountered a missing staged asset; an isolated
+  production build and complete bundle check passed with all 5,529 objects.
+  Validation output is under `artifacts/boss-cards/account-build`.
+
+## Main-menu talents and controls — 2026-09-14
+
+- Added Talents, Keybinds, and Button assignments destinations using the existing
+  editors. RoM characters show their automatically ranked Skills instead of
+  a talent-point editor. Closing a panel or using Back returns to the main menu.
+- A menu-only character subscription initializes the selected character and
+  saves talent ranks and controller ability assignments without mounting the
+  dungeon simulation. Level, experience, inventory, and equipment are preserved.
+  Keyboard bindings and WoW bar assignments retain the existing profile saving
+  behavior; keybind drafts require Save changes.
+- Live offline browser QA at 1280x720 opened all three editors for the level-17
+  Priest Rolecheck. The talent tree showed eight available points, controls
+  showed the character's skill names, and the assignment picker showed current
+  Smite and future unlock levels. Canceling a keybind edit and using Done returned
+  correctly; Escape first canceled the ability picker and then closed the editor.
+  This browser pass did not change the character's build or saved controls.
+- At a 390x844 viewport, the talent dialog's measured bounds fit the screen,
+  with no horizontal content overflow and a visible main-menu Back button.
+  Browser screenshot scaling was unreliable at this override; visual evidence
+  below covers the default desktop viewport. Physical gamepads and cloud saves
+  were not exercised.
+- Persistence tests cover allocation, reset, assignment, reopening, storage
+  failure, and owner/selection/phase/close isolation. UI and profile regressions
+  passed. TypeScript, production bundling, and complete release-bundle validation
+  passed after retrying a shared-output staging race; release hygiene passed.

+## AYN Thor physical-size UI review — 2026-09-14
+
+- Browser profiles use the Thor's 6-inch 1920x1080 upper panel and 3.92-inch
+  1240x1080 lower panel. Panel sizes come from
+  [AYN's specifications](https://www.ayntec.com/products/ayn-thor); resolutions
+  are also documented in the
+  [Thor manual](https://ae-pic-a1.aliexpress-media.com/kf/S21d979b6c8d840ddaebfeb976094e0cfP.pdf).
+  Derived physical rectangles are 132.8x74.7 mm and 75.1x65.4 mm. At a common
+  160 CSS pixels per inch, browser viewports are 837x471 and 473x412, with
+  independent device scale factors. A 44-pixel control represents about 7 mm
+  on either panel. The combined preview uses these relative physical sizes.
+- Dungeon defaults put party/self health, targets, minimap, and encounter
+  information upstairs. Controller actions, cast bar, buffs/debuffs, experience,
+  and DPS meter appear downstairs. Shared HUD components render once on their
+  assigned panel; the old duplicate tactical party-health panel is replaced.
+- Every HUD element has Top / Bottom / Hidden in the mobile UI editor. Touch
+  dragging from the lower page updates the upper page's authoritative draft.
+  Selection raises the widget above overlapping controls. Save, cancel,
+  reset, rapid reopening, and a full reload/dungeon reentry were verified.
+  Legacy templates without a screen field retain their defaults. Single-screen
+  play keeps visible elements on its primary display.
+- Enlarged text, icons, and touch controls; corrected roster, creator, class
+  hall, downloads, and dungeon/role layouts for the actual panel dimensions.
+  Character creation uses the lower model preview. Editor controls scroll with
+  Save and Cancel kept visible. Buff tooltips and the completion banner use
+  readable text; a lower-screen completion banner wraps its buttons below it.
+- Edge browser QA uses two Android/touch-emulated pages in one isolated offline
+  context. BroadcastChannel carries actual snapshots and touch commands between
+  pages. Covered login, empty/populated roster, both creation steps, main menu,
+  class hall, menu talents/keybinds/button assignments, reports, downloads,
+  dungeon/role selection, gameplay, pause, map, party, boss guide, spellbook,
+  talents, ability controls, inventory, boss cards, options, keybinds, issue
+  reporting, UI editor, defeat/respawn, completion/results, and combined preview.
+- Verified lower action casting changes the upper combat cooldown; party frames
+  can move downstairs, hide, save, reload, and select the player remotely.
+  Buff inspection opens by touch. Results open automatically and can reopen
+  from the banner; finishing through the lower banner returns both pages to
+  the main menu. Completion uses an isolated presentation fixture, rather than
+  a live boss clear. Dungeon captures include equipped fallback bodies; this
+  review does not establish authentic race-model loading.
+- All 42 layout, keybind, HUD-layering, display, snapshot, and dual-screen
+  regressions passed. A complete production build with asset audits and release
+  bundle validation passed; final UI edits also passed production compilation.
+  Browser captures have no unscrollable controls clipped outside their panel
+  and no uncaught UI errors. Physical hardware, Android WebView installation,
+  live online grouping, and shelved game modes were not exercised.
+- Reproduce with `node scripts/playtest-thor-ui.cjs` while Vite runs at port
+  5176, or set `THOR_TEST_URL`. Evidence is in
+  `playtest-artifacts/thor-ui/results.json` and paired PNGs, including
+  `14-final-defaults`, `14d-results`, `14e-complete-bottom`, and
+  `15-combined-preview.png`.
+
+## Boss Testing (2026-09-14)
+
+- Main menu now opens a searchable boss catalog with game and readiness
+  filters, selected-boss fights, and random fights. Selecting a boss installs
+  its missing dungeon content pack and dependencies automatically.
+- Testing uses an empty procedural room with one initial boss. Existing
+  combat, encounter phases, summoned adds, and relevant mechanic objects are
+  retained. Tests grant no experience, loot, or boss cards, and do not persist
+  changes to the character's progression or inventory.
+- Pause and victory review offer Ready, Needs testing, and Not ready labels,
+  boss-specific reports, retry, and return to the main menu. Labels persist
+  through the server, with local pending saves retained while offline.
+- Regression checks passed: 98 focused client tests, 19 server tests, and a
+  complete production build with asset audits and release bundle validation.
+- Production Edge playtest passed selection, active Lady Anacondra mechanics,
+  all three readiness labels, report submission, retry, victory review,
+  persistence, random selection, and a 390-pixel mobile layout without
+  horizontal overflow. Victory uses deterministic damage through the combat
+  store; this is not a natural full-fight clear. Experience and saved character
+  data were unchanged, and no uncaught browser errors occurred.
+- Selecting Taragaman the Hungerer from an uninstalled Ragefire Chasm pack
+  downloaded the pack and dependencies, then loaded the boss model and active
+  mechanics in the test room. A second browser page received the testing room
+  snapshot and opened boss review through the lower-display button. Physical
+  dual-screen hardware was not exercised.
+- Reproduce with `node scripts/playtest-boss-testing.cjs`; the script starts
+  an isolated production server and test database. Evidence is in
+  `playtest-artifacts/boss-testing/results.json` and screenshots
+  `01-main-menu.png` through `12-bottom-display-review.png`.
+
+### Boss Testing health correction
+
+- Testing rooms now use the boss's authored health at the scaled enemy level,
+  without the campaign durability floor or final-boss bonus. A lone testing
+  objective previously made every selected boss qualify as a campaign finale.
+  At character level 1 this produced a 10,987 HP minimum instead of Celebras
+  the Cursed's 575 HP from his level-2 native stats and authored multiplier.
+- Regression checks passed: 24 tests covering testing, campaign boss balance,
+  level scaling, asset preparation, and display snapshots. A full production
+  build passed its asset audits and release bundle validation.
+- Production Edge playtest confirmed a level-1 WoW Priest fighting a level-2
+  Celebras with 575 maximum health. The boss model and active mechanics were
+  visible, and readiness labels, reports, retries, victory review, random
+  selection, mobile layout, automatic downloads, and lower-display review
+  passed without uncaught errors. Victory still uses deterministic damage;
+  natural time to defeat was not measured.
+- Reproduce in PowerShell with `$env:BOSS_TEST_BOSS = 'Celebras the Cursed'`
+  followed by `node scripts/playtest-boss-testing.cjs`. Evidence is in
+  `playtest-artifacts/boss-testing-scaling/results.json` and paired screenshots.
+
+### Regular dungeon health correction
+
+- Regular dungeon scaling now selects the durability minimum using the
+  character's game. WoW uses an interpolated level curve, RoM uses 1.15 times
+  the expanded-class baseline, and CoA uses 1.75 times that baseline. These
+  independently calibrated floors keep every canonical class-role build above
+  the same 25-second ordinary and 45-second final-boss mechanic windows. Native
+  authored health can still exceed the floor. Final-boss and difficulty bonuses
+  remain part of campaign scaling. Boss Testing continues using scaled authored
+  health without a campaign minimum.
+- On Easy, a level-3 WoW Priest now encounters a level-4 Targorr the Dread with
+  1,300 HP in regular Stockades, compared with the prior shared 10,766 HP
+  minimum. The WoW final boss has a 2,340 HP minimum at that level; equivalent
+  RoM and CoA parties receive 7,074.8 and 10,766 HP ordinary-boss floors.
+- Level-3 WoW Priest simulations with three companion seeds cleared the opening
+  boss in 25.7-43.6 seconds and the final boss in 48.2-79.6 seconds. These timing
+  samples assume companions are in range and omit boss attacks; a separate
+  level-3 test verifies real boss attacks execute during the shortened fight.
+- Validation passed for all 271 application test files: 1,759 tests passed and
+  six were skipped. The shared balance cohort covers every WoW, RoM, and CoA
+  class-role build at levels 8, 20, 40, and 80 with three deterministic seeds.
+- The earlier production Edge capture recorded the intermediate 1,200 HP WoW
+  floor and is superseded by the final 1,300 HP calibration. The browser script
+  now checks the final value; a new live screenshot has not been recorded.
+- Reproduce with `node scripts/playtest-dungeon-health.cjs`. Browser evidence is
+  in `playtest-artifacts/dungeon-health-scaling/results.json` and
+  `stockades-level-three.png`. Run the scaling tests with `BOSS_BALANCE_REPORT=1`
+  to record companion timing samples in `artifacts/boss-difficulty/ragefire-balance.json`;
+  the all-class report is `artifacts/boss-difficulty/wow-rom-coa-balance.json`.
