+## 2026-09-23 (formats cleanup)
+
+The previous section's next action: `formats` values that are not formats. One commit,
+`40a6010`, 20 entries.
+
+- Removed where real formats were already listed: `many`, `runtime`, `shaders`,
+  `spreadsheet`, `Kinect`, `model` (beside `ONNX`), `config`, `examples`, `binary`.
+- Software with no file format of its own now names a **delivery type**: `desktop-app`
+  (5 entries), `mobile-app`, `cli` (2); `JS API` became the `JavaScript` target.
+- Moved to `tags`: `windows`, `macos`, `ios`, `heightfield`, and `variable` as
+  `variable-font` on 5 fonts (Inter's existing `variable` tag renamed to match).
+- CONTRIBUTING now defines four kinds of `formats` value (file formats, engine or
+  language targets, delivery types, `various` for aggregators) and no longer claims every
+  extension is upper case, which `gdshader`, `tmx` and `ktx2` already contradicted.
+- Nothing invented: Gaea and Piper name no output format in their entries, so they get a
+  delivery type rather than a guessed file type.
+- Not enforced by a check. The delivery-type list is short and could become a V13-style
+  vocabulary later if it drifts.
+- **The review queue is now empty of work that does not need the maintainer.** What is
+  left is three decisions, carried since the first run.
+- Next highest-value action: **the three maintainer decisions**, with a recommended
+  default for each so a yes is enough:
+  - `og:image`: a first-party 1200x630 PNG of the site under `docs/images/readme/`, the
+    path the validator already allows for first-party stills. Hard rule 3 covers
+    third-party binaries, not the project's own screenshot.
+  - `data.json` (297 KB, unused by the page): keep it and document it in `site/README.md`
+    as the catalog's public JSON endpoint. Removing it breaks anyone already using it.
+  - `camera_perspective`: keep it 2D-only, and say so in TEMPLATE. `characters` and `3d`
+    have no perspective in the 2D sense, and the View filter already explains itself.
