 Interpret the two together:
 
-- **Failing model absent from the `curl` output** → it was delisted upstream (for example `ox-alpha-free`, removed from the relay on 2026-09-09). A picker can still offer it from a **stale catalog merge**: Hermes core merges its own curated Go list into the live result, and Agent releases *between* v0.20.5 and the 2026-09-09 catalog sync (through v0.21.1) still carry the delisted id in that list — verified at runtime against v0.21.0, where the live path serves 37 ids including `ox-alpha-free`. **Upgrade the Agent** past the 2026-09-09 sync (or pin an allowlist below) so the dead id stops being offered.
+- **Failing model absent from the `curl` output** → it was delisted upstream (for example `ox-alpha-free`, removed from the relay on 2026-09-09). A picker can still offer it from a **stale catalog merge**: Hermes core merges its own curated Go list into the live result, and every Agent release *through v0.21.1 (tag `v2026.9.7`)* still carries the delisted id in that list — verified at runtime against v0.21.0, where the live path serves 37 ids including `ox-alpha-free`. The removal is committed on core `main` (2026-09-09 sync) but **no released Agent version includes it yet** — and `main` reports the same `0.21.1` version string as the stale tag, so a version number alone cannot tell you whether the fix is in. Until a release notes the 2026-09-09 catalog sync, the **verified workaround is the config allowlist** (below); selecting the dead entry is harmless to other models (it errors on send, nothing else).
 - **Failing model present in the `curl` output** → the relay lists it but your tier/region cannot serve it; the picker is behaving correctly. Pin the models you actually use with an explicit allowlist in `config.yaml`, which takes precedence over both the live catalog and the fallback:
