@@ -101,6 +101,8 @@
 - **fix(memory):** extract system role messages in semantic passthrough path to prevent 400 on memory injection — system messages were being passed as-is to providers that reject mixed roles. ([#2474](https://github.com/diegosouzapw/OmniRoute/pull/2474) — thanks @Tentoxa)
 - **fix(@omniroute/opencode-provider):** include `limit.context` in model entries for OpenCode context window detection — previously OpenCode couldn't determine model context size. ([#2482](https://github.com/diegosouzapw/OmniRoute/pull/2482) — thanks @herjarsa)
 - **fix(mimo):** add `supportsVision` flag to Kimi K2.6 in providerRegistry + comprehensive vision tests for MiMo V2.5/V2.5-Pro/V2-Omni. ([#2600](https://github.com/diegosouzapw/OmniRoute/pull/2600) — thanks @herjarsa)
+- **fix(proxy):** prefer scoped proxies over registry global fallback — legacy provider-specific proxy was being shadowed by a registry-global fallback across both storage backends. Resolution now follows strict specificity: account → provider → combo → global. ([#2606](https://github.com/diegosouzapw/OmniRoute/pull/2606) — thanks @terence71-glitch)
+- **fix(@omniroute/opencode-plugin):** canonical-twin dedup + alias-fallback enrichment — `/v1/models` returned the same model under both alias (`cc/claude-opus-4-7`) and canonical (`claude/claude-opus-4-7`) names; now drops ~75 canonical duplicates and rescues ~88 raw-id rows with proper provider prefix via alias-index fallback. Also emits `cost`, `release_date`, `modalities` fields in static catalog and raises provider label threshold to 12 chars (preserves `AssemblyAI`, `Antigravity` verbatim). ([#2607](https://github.com/diegosouzapw/OmniRoute/pull/2607) — thanks @mrmm)
