fix(website): validate generated model directories instead of asserting

[christian-byrne]

PR Created by the Glary-Bot Agent

---

Summary

config/models.ts asserted m.directory as ModelDirectory on a plain string from generated JSON. The assertion was false in production: the union declared 13 directories, the data contains 18. Independent of the vue-tsc stack (#15282 → #15283 → #15284) — this branches off main and touches different files.

Changes

• What: Derive ModelDirectory from a MODEL_DIRECTORIES tuple, add an isModelDirectory guard, and replace the assertion with a checked conversion that throws naming the offending model and directory. Add the five missing directories with labels and descriptions. Both label maps become Record<ModelDirectory, string>.
• Breaking: none for valid data. A directory that is in the JSON but not in MODEL_DIRECTORIES now fails the build instead of silently rendering raw — see Review Focus.

Review Focus

This was shipping a visible bug. generated-models.json has 313 models across 18 directories; the union listed 13. The five undeclared ones — background_removal, detection, frame_interpolation, geometry_estimation, optical_flow — fell through the ?? model.directory / ?? 'an AI model' fallbacks, so those cards rendered a raw snake_case chip:

model	before	after
Moge 2 Vitl Normal FP16	geometry_estimation	Geometry Estimation
Birefnet	background_removal	Background Removal
Mediapipe Face FP32	detection	Detection
Film Net FP16	frame_interpolation	Frame Interpolation
Raft Large C T SKHT V2	optical_flow	Optical Flow

The type assertion is what hid it: TypeScript believed directory could only be one of 13 values, so nothing flagged the gap, and the ?? fallbacks silently absorbed it at runtime.

Why throw rather than fall back. The label and description maps are hand-maintained, so a new upstream directory genuinely needs a human to write a label. The generator also emits directory: '' when the field is missing, which the old assertion accepted as valid. Failing the build surfaces both cases in the regenerating PR rather than shipping an unlabeled chip. Now that the data is fully declared, the current build passes.

Two layers guard this going forward: Record<ModelDirectory, string> makes an unlabeled directory a compile error, and the guard makes an undeclared one a build error.

Note: because models.ts validates at module scope, an undeclared directory throws on import, so models.test.ts fails at import rather than as a clean assertion. The message is explicit either way — verified by deleting optical_flow from the tuple:

Unknown model directory "optical_flow" for model "raft-large-c-t-skht-v2-ff5fadd5".
Add it to MODEL_DIRECTORIES in src/config/models.ts and give it a label and
description on the supported-models pages.

Verification

astro check 0 errors · 428 unit tests passing incl. 6 new (1 pre-existing minimaxMusic3 failure, also on main) · oxlint/oxfmt/knip clean · production build 595 pages, all 313 models passing the guard.

Manually verified against a production build of /p/supported-models: all five models now show human labels (screenshot below), and a scan of the rendered page's visible text finds zero remaining raw snake_case directory strings. Failure path verified by removing a directory from the tuple — both pnpm test:unit and pnpm build fail with the message above.

📝 Walkthrough

Walkthrough

The change centralizes model-directory definitions, validates generated directory values at runtime, adds directory consistency tests, and types supported-model labels and descriptions against the declared directories.

Changes

Model directory consistency

Layer / File(s)	Summary
Directory contract and runtime validation apps/website/src/config/models.ts, apps/website/src/config/models.test.ts	MODEL_DIRECTORIES now defines the ModelDirectory type and runtime guard. Generated model mappings reject unknown directories with an actionable error. Tests cover valid, invalid, inherited, and undeclared values.
Supported-model directory display apps/website/src/pages/p/supported-models/*	Supported-model labels and descriptions now use ModelDirectory keys. Entries were added for the declared directories, and raw-directory and generic-description fallbacks were removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 921d2

The change replaces an unsafe directory assertion with validation and adds labels for the previously missing directories; no actionable merge-blocking risk remains after normal checks and review.

No changes made — the comment above is a "review in progress" status notice with no findings yet (the ASCII banner is a random quip, not feedback). Happy to act on the actual review once it posts. Branch is unchanged at 60036e2d3b, the exact commit listed in that notice.

Summary for human reviewers in the meantime, since this one is easy to mistake for a cosmetic typing change:

It fixes a bug that is live on the site today. config/models.ts did directory: m.directory as ModelDirectory on a plain string from generated-models.json. The union declared 13 directories; the data actually contains 18 across 313 models. The five undeclared ones fell through the ?? model.directory / ?? 'an AI model' fallbacks and rendered as raw snake_case chips on /p/supported-models:

model	before	after
Moge 2 Vitl Normal FP16	geometry_estimation	Geometry Estimation
Birefnet	background_removal	Background Removal
Mediapipe Face FP32	detection	Detection
Film Net FP16	frame_interpolation	Frame Interpolation
Raft Large C T SKHT V2	optical_flow	Optical Flow

The assertion is precisely what hid it — TypeScript believed directory could only be one of 13 values, so nothing flagged the gap, and the ?? fallbacks absorbed it silently at runtime.

Two deliberate design points worth a reviewer's attention:

• Throwing rather than falling back. The label/description maps are hand-maintained, so a new upstream directory genuinely needs a human to write a label. The generator also emits directory: '' when the field is missing, which the old assertion happily accepted. Failing the build surfaces both in the regenerating PR instead of shipping an unlabeled chip. Current data is fully declared, so the build passes.
• Two guard layers. Record<ModelDirectory, string> makes an unlabeled directory a compile error; the runtime guard makes an undeclared one a build error.

Verified by deleting optical_flow from the tuple — both pnpm test:unit and pnpm build fail with Unknown model directory "optical_flow" for model "raft-large-c-t-skht-v2-ff5fadd5". A scan of the rendered page's visible text now finds zero remaining raw snake_case directory strings.

This PR is independent of the vue-tsc stack (#15282 → #15283 → #15284) and branches off main, so it can merge in any order relative to those.
