```

GLBs keyed by URL as written in the scene model, before `assetBaseUrl` (a twin by its stored
name). A node walks spec section 6.4's chain: `optGlbUrl`, its plain twin, `glbUrl`, its plain
twin (a twin only for a `.holo`). A URL other than `glbUrl` with no entry is skipped, with no
Problem. An entry whose `load.fail` is set fails as that URL's fetch, decrypt or key would and
the chain goes on: a later entry that loads records 'asset-degraded' (`url` the first URL that
failed); none records 'asset-failed' (`url` the last URL tried). A `.holo` entry needs no key
material. A `glbUrl` with no entry fails as a load does, and its 'asset-failed' message says
the entry is missing, its `didYouMean` the keys with the same or a close file name (an
absolute `glbUrl` beside a bare key, a typo); a node with no or empty `glbUrl` needs none and
loads nothing.

**Default:** {}

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `models` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
