 - New expression semantics must be declared as `domain_expression_*` contracts in `components/domain/include/domain.h` and mapped in the domain runtime adapter catalog.
 - Upper layers must request expressions through `domain_runtime_request_expression()`; they must not call `platform_lcd_*` playback APIs directly.
 - Platform LCD code must expose playback primitives only and must not reference `DOMAIN_EXPRESSION_*` semantic IDs.
-- Asset-backed expressions should place `.bin` frames under `components/platform/assets/lvgl_animations/<asset_dir>/`; custom playback order belongs in the domain catalog, not in duplicated asset files or control-plane logic.
+- Asset-backed expressions should use the platform-owned direct LCD asset path documented in `docs/lcd-expressions.md`; custom playback order belongs in the domain catalog, not in duplicated asset files or control-plane logic.
 - Do not add one-off expression APIs for each emotion/state unless an ADR explicitly justifies a new contract family.

 ## Playback Scheduling
 
 The platform LCD presentation scheduler is non-blocking:
 
 - Requests are copied at API entry.
-- LVGL objects are created, deleted, and mutated only inside the LCD render task.
+- Panel drawing is serialized by the LCD render task.
 - Same active or pending requests are coalesced.
 - Higher-priority interrupting requests replace the active presentation.
 - Lower-priority requests are ignored while a higher-priority presentation is
   active or pending.
-- Asset-backed expressions are cached after their frames are decoded. The LCD
-  task preheats the `spin` asset after startup and preheats the selected wealth
-  direction reveal while the fixed spin intro is playing.
-- Preheat requests do not change the active display. They decode incrementally
-  during the render loop, and playback finishes any remaining decode work
-  synchronously if a reveal is requested before preheat completes.
 
 Current priorities:
 
 | Presentation | Priority | Interrupts current |
 | --- | --- | --- |
 | Wi-Fi disconnected / idle restore | `120` | Idle restore interrupts Wi-Fi disconnected. |
-| Wealth spin / wealth-direction reveal | `110` | Yes (spin interrupts current; the reveal follows after the spin completes). |

 | Server error | `100` | Yes |

-The wealth spin/reveal pair is requested by the model-command direction worker
-(`control_plane_model_command_task`): the spin plays exactly twice as a blocking
-intro while the selected reveal is preheated, then the reveal is requested and
-the motor rotation starts together. At priority `110` a Wi-Fi-disconnected
-screen (`120`) still wins, so the reveal is suppressed while STA is down —

-This section reflects the actual state of the repository and takes precedence over older assumptions.
-
-### 0.1 Scope approved in this round
-
-- Introduce LVGL using `lvgl/lvgl = 9.2.0`.
-- Use a single ST7789V panel.
-- Do not use shared SPI for multiple LCD panels.
-- Follow LCD GPIO mapping from `docs/gpio-map.md`.
-- Keep layered architecture unchanged: `app_composition -> control_plane -> domain -> platform`.
-
-### 0.2 Completed progress
-
-1. LVGL dependency was added and locked to `9.2.0`.
-   Evidence: `main/idf_component.yml:3`, `dependencies.lock:64`, `dependencies.lock:70`.
-2. LCD runtime was migrated from JPEG demo rendering to `esp_lcd + lvgl`.
-   Evidence: `components/platform/CMakeLists.txt:13`, `components/platform/CMakeLists.txt:49`, `components/platform/CMakeLists.txt:58`, `components/platform/src/lcd.c:367`, `components/platform/src/lcd.c:401`, `components/platform/src/lcd.c:429`, `components/platform/src/lcd.c:543`.
-3. Single ST7789V panel path is active.
-   Evidence: `components/platform/src/lcd.c:2`, `components/platform/src/lcd.c:401`, `components/platform/src/lcd.c:496`.
-4. LCD pin mapping matches the GPIO map document.
-   Evidence: `docs/gpio-map.md:16`, `docs/gpio-map.md:18`, `docs/gpio-map.md:19`, `docs/gpio-map.md:20`, `docs/gpio-map.md:24`, `docs/gpio-map.md:26`, `components/platform/src/lcd.c:35`, `components/platform/src/lcd.c:36`, `components/platform/src/lcd.c:37`, `components/platform/src/lcd.c:38`, `components/platform/src/lcd.c:39`, `components/platform/src/lcd.c:40`, `sdkconfig.defaults:81`.
-5. Build passed after integration.
-   Evidence: local run `idf.py fullclean && idf.py build` completed successfully.
-6. No runtime `gc9a01` dependency remains under `components` and `main`.
-   Evidence: `rg -n "gc9a01|GC9A01" components main` returned no matches.
-
-### 0.3 Still missing
-
-1. GIF business pipeline is not implemented yet in the current codebase.
-   Missing modules include `components/gifdisplay/*`, GIF package loading, preload, and runtime switching.
-2. Emotion-driven GIF switching path is not implemented (`components/emotion/*` is absent).
-3. The current LVGL UI is a baseline default screen, not GIF playback UI.
-4. Device-side GIF runtime logs are not available yet (`Switching gifs...` class logs are not present in runtime code).
-
-### 0.4 Differences vs the original baseline description
-
-1. Panel topology:
-   Original baseline: dual GC9A01.
-   Current implementation: single ST7789V.
-2. LVGL version:
-   Original baseline: `9.4.0`.
-   Current implementation: `9.2.0` (explicitly requested in this round).
-3. Display stack:
-   Original baseline references an older code layout and line map.
-   Current repository uses the layered runtime path and a rewritten `components/platform/src/lcd.c` implementation.
-4. GIF status:
-   Original baseline assumes full GIF chain exists.
-   Current repository does not yet include GIF runtime components.
-
-### 0.5 Environment note
-
-- `AGENTS.md` requires ESP-IDF `5.5.2` setup instructions.
-  Evidence: `AGENTS.md:31`.
-- The actual local verification in this round used ESP-IDF `5.5.1` because that environment path exists locally.
-  Evidence: `dependencies.lock:63`.
-
-## Section A: Reality Check + Runtime Call Graph (Current Repository)
-
-### A.1 Reality Check
-
-1. LVGL runtime path is now present in production LCD code (not only a test utility).
-   Evidence: `components/platform/src/lcd.c:415`, `components/platform/src/lcd.c:429`, `components/platform/src/lcd.c:479`, `components/platform/src/lcd.c:543`.
-2. GIF playback path is not present in runtime code.
-   Evidence: `rg -n "gifdisplay|lv_gif|gifpack" components main` has no runtime hits.
-3. `app_main` still starts LCD through layered interfaces.
-   Evidence: `main/main.c:285`, `components/app_composition/src/app_composition_runtime_support.c:65`, `components/control_plane/src/control_plane_runtime_support.c:39`, `components/domain/src/domain_runtime_support.c:39`, `components/platform/src/platform_runtime_support.c:176`.

-## Section C: GIF Pipeline Status
-
-### C.1 Current status
-
-- `UNKNOWN` as implemented feature in this repository branch: full GIF runtime pipeline.
-- No `gifdisplay` component exists in current source tree.
-- No `emotion` component exists in current source tree.
-
-### C.2 Required future implementation (not done yet)
-
-1. Add GIF runtime owner component (recommended: `components/gifdisplay`).
-2. Add GIF asset packaging and partition-read path.
-3. Add GIF widget playback path in LVGL (`lv_gif_set_src` or equivalent strategy).
-4. Add business trigger path from runtime state to GIF switching.
-5. Add startup preload / timeout / rollback strategy consistent with target behavior.
-
-## Section D: Layering and Dependency Compliance
-
-Current layered dependency chain remains valid:
-- `app_composition` depends on `control_plane`.
-  Evidence: `components/app_composition/CMakeLists.txt:11`.
-- `control_plane` depends on `domain`.
-  Evidence: `components/control_plane/CMakeLists.txt:13`.
-- `domain` depends on `platform`.
-  Evidence: `components/domain/CMakeLists.txt:13`.
-- `platform` owns runtime LCD integration directly (no separate `lcd` component dependency).
-  Evidence: `components/platform/CMakeLists.txt:13`, `components/platform/src/platform_runtime_support.c:11`, `components/platform/src/platform_runtime_support.c:176`.
-
-## Section E: Verification Matrix
-
-### E.1 Completed in this round
-
-| Check | Command | Result |
-|---|---|---|
-| Build | `idf.py fullclean && idf.py build` | Passed |
-| LVGL dependency | lockfile inspection | `lvgl/lvgl = 9.2.0` |
-| GC9A01 runtime residue | `rg -n "gc9a01|GC9A01" components main` | No matches |
-
-### E.2 Pending for next round
-
-| Check | Command | Expected |
-|---|---|---|
-| Device runtime LVGL stability | `idf.py -p <PORT> flash monitor` | No frequent flush/panel failures |
-| GIF startup and switching | Same monitor run with GIF triggers | GIF load and switching logs present |
-| Long-run behavior | Continuous run test | Stable memory and frame updates |
-
-## Section F: Risks and Open Items
-
-1. The guide originally describes a complete GIF stack, but the current repository does not include those modules yet.
-2. The current implementation is LVGL-base-only; GIF behavior parity is still pending.
-3. Environment parity risk exists if strict ESP-IDF `5.5.2` compliance is mandatory.
-4. Performance targets (FPS/CPU/memory thresholds) are not yet defined in code-level acceptance criteria.
-
-## Section G: Minimal File Set (Current State)
-
-Implemented in this round:
-- `main/idf_component.yml`
-- `dependencies.lock`
-- `components/platform/CMakeLists.txt`
-- `components/platform/internal/lcd.h`
-- `components/platform/src/lcd.c`
-
-Not yet implemented but required for full GIF parity:
