+Save data lives under `src/dusk/save/` (`save.h`/`savefile.h`/
+`saveplatform.h`). Slots are fixed-count (`SAVE_FILE_COUNT_MAX`), each
+holding a yyjson document persisted with its byte size and a CRC32
+checksum. `saveLoad`/`saveSave` read/write the JSON fresh every call —
+callers own the returned/passed `yyjson_doc`/`yyjson_mut_doc` and must
+free it themselves. Actual file I/O goes through platform-specific
+`saveplatform_t`/stream hooks (one implementation per platform under
+`src/dusk<platform>/save/`) — do not add direct filesystem calls to the
+core `save.c`, extend the platform stream hooks instead.
+
+## Network system
+`src/dusk/network/` (`network.h`) is a connection-state layer only — a
+`networkstate_t` state machine (`DISCONNECTED`/`CONNECTING`/`CONNECTED`/
+`DISCONNECTING`) plus an HTTP client (`network/http/`) used for one-off
+requests. It is not a multiplayer/replication protocol — that layer
+doesn't exist yet (see `ROADMAP.md` items on the socket server/client
+and packet handlers). Platform-specific connection logic (e.g. PSP's
+`sceNetApctl` polling, GameCube/Wii's `if_config()`) lives under
+`src/dusk<platform>/network/`, wired through `networkplatform.h` macros
+the same way display/input are. Whenever this eventually grows a
+multiplayer protocol, apply `ROADMAP.md`'s principle: never trust
+incoming packet data — validate defensively with `errorret_t`/
+`errorThrow()`, not asserts.

+Found during a full-codebase inventory pass (2026-07-30, see `STATUS.md`
+for the full survey). These aren't new feature milestones so much as
+loose ends worth closing, roughly in order of how cheap/safe they are to
+fix:
+
+1. Re-enable `test/item` (currently commented out in
+   `test/CMakeLists.txt`) -- confirm it still passes and turn it back on.
+2. Restore `itemgive.c/h` in `src/duskrpg/item/CMakeLists.txt` -- the
+   textbox UI dependency it was waiting on (`ui/textbox/`) is already
+   back.
+3. Decide the fate of the `vita` target: `scripts/build-vita.sh` and
+   `docker/vita/` reference `-DDUSK_TARGET_SYSTEM=vita`, but no
+   `cmake/targets/vita.cmake` exists, so the build is currently broken.
+   Either implement it or remove the dangling scripts/Dockerfile.
+4. Add per-PR CI build coverage for at least one non-Linux target (PSP,
+   Knulli, GameCube, Wii currently only build on tag push, so
+   regressions there are invisible until a release).
+5. Tackle milestone 4 above (poor UI rendering performance) with a
+   concrete lead: extend `uiconsole.c`'s cached-mesh pattern (rebuild
+   only on dirty) to the general widget framework
+   (`uiframe.c`/`uilabel.c`/buttons/menus), which currently rebuilds and
+   re-uploads geometry via `spriteBatchBuffer`/`meshFlush` every frame.
+6. Revisit the GameCube/Wii networking static-IP workaround in
+   `networkdolphin.c` -- it's standing in for an unresolved suspected
+   memory-corruption bug in `if_config()`'s DHCP path.
+7. Decide whether the PSP dialog-based network connect UI needs to come
+   back -- it was removed entirely (not fixed) when the original
+   dialog-tearing bug proved hard to resolve.
+8. Backfill unit tests for the biggest untested surfaces: `ui/` (whole
+   widget framework), `save/`, `script/` (JerryScript bindings), `event/`.

 - Never trust the network implicitly. Neither side (server or client)

+# Dusk Engine - Status Snapshot
+
+This is a point-in-time inventory of the codebase's maturity, test coverage,
+and known gaps. It is not auto-maintained -- re-survey periodically (or
+whenever picking a new roadmap milestone) rather than trusting it blindly.
+See `ROADMAP.md` for the ordered feature milestones this status feeds into,
+and `CLAUDE.md` for coding conventions.
+
+Last surveyed: 2026-07-30, at commit `e61914ba`.
+
+## Core engine (`src/dusk/`)
+
+| Subsystem  | Maturity                          | Notes |
+|------------|------------------------------------|-------|
+| asset      | Mature, fully wired                | Model loading's "async" path is actually synchronous (`assetmodelloader.h`) -- only real stub found in core. |
+| script     | Mature for its current scope       | Registered modules: `modulePlatform`, `moduleComponent`, `moduleEntity`, `moduleScene` only. No typed per-component JS wrappers (all components go through the generic `Component`). No unit tests. |
+| entity     | Mature                             | Engine-level prefab lists are empty sentinels; all real prefabs live in `duskrpg`. |
+| scene      | Mature                             | Same prefab-delegation pattern as entity. No JSON serialize/deserialize (removed by design). |
+| save       | Mature, but undocumented           | Slot-based, yyjson + CRC32, platform stream hooks. Not covered in `CLAUDE.md`, no tests. |
+| network    | Connection-state layer only        | HTTP client + connection state machine; no multiplayer/replication protocol (expected -- that's roadmap items 8-17). Not covered in `CLAUDE.md`, has HTTP tests only. |
+| physics    | Mature, recently churned           | Recent revert/re-disable of "old ent code" suggests component wiring around physics isn't fully settled. Well tested. |
+| animation  | Early/mid-stage                    | Keyframes + easing only, no blend trees or state machines. Terse commit history ("ANIM") suggests still iterating. |
+| display    | Most mature/battle-tested          | Backbone of the engine; dominated by platform optimization commits. |
+| ui         | Actively churning                  | Widget framework has had features added and ripped out repeatedly (story/battle UI added then removed). Rendering path is the likely root cause of roadmap item 4 (see below). No tests at all. |
+| console    | Small, finished for its scope      | Already has the cached-mesh optimization pattern the rest of `ui/` lacks. |
+| event      | Clean, small, finished             | Pub/sub, rebuilt to replace the old input system. |
+| game       | Intentionally header-only          | Real implementation lives in `duskrpg/game/game.c`. |
+
+### UI rendering performance (roadmap item 4)
+Confirmed root-cause candidate: `src/dusk/ui/debug/uiconsole.c` caches a
+persistent mesh and only rebuilds on dirty/scroll change. The rest of the
+widget framework (`uiframe.c`, `uilabel.c`, buttons, menus, settings
+screens) still goes through `spriteBatchBuffer`/`spriteBatchFlush` and
+re-uploads vertex data via `meshFlush` every frame, with a full flush
+forced on every shader/material change. This is almost certainly what
+"tanks framerate" on PSP. Fix direction: extend the console's cached-mesh
+pattern to the general widget path (rebuild only on dirty, not every
+frame).
+
+## Game layer (`src/duskrpg/`)
+
+Actively maintained, not orphaned (despite an old "remove rpg" commit deep
+in history) -- last touched the same day as this survey.
+
+- **cutscene/** -- actively developed, matches `CLAUDE.md`'s documented
+  recipe exactly. 16 registered item types.
+- **entity/, scene/** -- overworld player/camera/interactable components
+  and prefabs, active.
+- **item/** -- `item.c`/`inventory.c`/`backpack.c` built via a working
+  `item.json` -> `itemdef.h` codegen pipeline. `itemgive.c/h` exist on
+  disk but are explicitly excluded from the CMake build pending textbox
+  UI restoration -- **that UI (`ui/textbox/`) is already restored**, so
+  this looks like an overdue follow-up, not a real blocker.
+- **input/** -- headers only, no implementation. Contains the one
+  genuine TODO found in the whole `duskrpg` tree: `// TODO: Wiimote, USB
+  Keyboard, probably more.`
+- **ui/** -- textbox restored and built; `uitestlabel.c/h` is an
+  intentional smoke-test scaffold, not dead code.
+
+## Platform layers
+
+| Platform     | Status |
+|--------------|--------|
+| duskgl / dusksdl2 | Complete, shared by Linux/Knulli/PSP, no gaps found. |
+| dusklinux    | Complete, well-trodden. |
+| duskpsp      | Complete for current design. The historical dialog/tearing bug (see memory `project_psp_dialog_tearing` etc.) was **not fixed -- the dialog-based connect UI was removed entirely** (commit `d7982599`, "Simplified PSP network") in favor of a silent profile-based connect. Revisit if the dialog UX is still wanted. |
+| duskdolphin (GameCube/Wii) | Functional, not a stub -- real GX-based display/mesh/shader/texture. Wii input uses only the GameCube `PAD_*` library; no WPAD/Wiimote support (`inputdolphin.h` has `#error "Wii not implemented"` gated behind macros that are never defined, so currently dormant, not a live build break). `networkdolphin.c` hardcodes a static IP as an explicit temporary workaround for a suspected DHCP-related memory-corruption bug in `if_config()` -- root cause still open. |
+| vita         | **Referenced by `scripts/build-vita.sh` and `docker/vita/` but no `cmake/targets/vita.cmake` exists** -- the build target is broken/unfinished at the CMake level. |
+
+### CI coverage gap
+`.github/workflows/test.yml` only builds+tests Linux, on PRs to `main`.
+`build.yml` builds all other platforms (PSP, Knulli, GameCube, Wii +
+ISO variants) but **only on tag push** (release time). Vita and Dolphin
+aren't in CI at all. Net effect: regressions on 4+ platforms can land
+silently until a release tag is cut.
+
+## Test coverage gaps
+
+Core `src/dusk/` subsystems with **zero** unit tests: `console`,
+`engine`, `event`, `game`, `input`, `log`, `save`, `script` (+ all JS
+module bindings), `system`, `ui` (entire widget framework).
+
+`src/duskrpg/` has almost no test coverage: `test/item/test_inventory.c`
+exists but **`add_subdirectory(item)` is commented out in
+`test/CMakeLists.txt`**, so even that one test never runs. `cutscene`,
+`entity`, `game`, `input`, `scene`, `ui` under `duskrpg` have no tests at
+all.
+
+No stale tests were found referencing deleted systems (old JSON
+serialize/deserialize, old event/cutscene modules) -- the test suite is
+internally consistent with current code, just incomplete in coverage.
+
+## Build/tooling gaps worth knowing about
+
+- `assetsraw/` -> `assets/` (chunk JSON -> `.dcf`) is a manual/editor-only
+  step (`tools.asset.chunk`), not part of the CMake build -- committed
+  `.dcf` files can silently drift from their raw source.
+- Several Python tool packages exist but aren't wired into any build:
+  `tools/color/csv/`, `tools/asset/chunk_json/`, `tools/asset/dmf/`,
+  `tools/asset/tiles/`, `tools/input/csv/`. Some may be superseded by
+  `tools/color.py`/`tools/item.py`; worth a pass to confirm which are
+  live vs leftover.
