HTTP 400 "invalid argument" was triggered when OmniRoute translated OpenAI
tool_calls to Gemini format, because thoughtSignature was injected onto every
functionCall part unconditionally.
thoughtSignature is only valid on thinking/reasoning parts (those with
thought: true). The Gemini API rejects any request where a functionCall
part carries a thoughtSignature field, returning HTTP 400.
Fix: remove the thoughtSignature field from functionCall parts. The thinking
parts that legitimately require thoughtSignature (emitted when a message has
reasoning_content) are unchanged.
Adds regression test (T43) with three cases:
- single tool call: no thoughtSignature on functionCall part
- multiple tool calls: none carry thoughtSignature
- thinking part regression guard: thoughtSignature still present on thought parts
Fixes#725
When all combo models are exhausted (502/503), OmniRoute now checks for
a globalFallbackModel setting and attempts one last request through it
before returning the error. Settings stored in key_value table, no
migration needed.
Non-streaming: Fixed json.messages check to use json.choices[0].message
(OpenAI format). Streaming: inject pin tag before finish_reason chunk for
tool-call-only streams. injectModelTag now appends synthetic assistant
message when content is null/array (tool_calls).
Adds a new /dashboard/cache page that surfaces the existing but UI-less
semantic cache infrastructure.
Changes:
- New page: src/app/(dashboard)/dashboard/cache/page.tsx
- Live stats: memory entries, DB entries, cache hits, tokens saved
- Hit rate progress bar with color coding (green/yellow/red)
- Hits/Misses/Total breakdown
- Idempotency layer stats (active dedup keys + window)
- Cache behavior info panel
- Clear All button
- Auto-refresh every 10s
- Enhanced API: src/app/api/cache/route.ts
- DELETE ?model=<name> — invalidate by model
- DELETE ?signature=<hex> — invalidate single entry
- DELETE ?staleMs=<ms> — invalidate entries older than N ms
- DELETE (no params) — clear all (existing behavior)
- Sidebar: added Cache nav item (icon: cached)
- i18n: added cache + sidebar.cache keys for all 31 supported locales
No new dependencies. All functionality builds on existing semanticCache.ts,
cacheLayer.ts, and idempotencyLayer.ts modules.

When Claude Code routes through OmniRoute (Claude → OmniRoute → Claude),
OmniRoute was stripping all cache_control markers and replacing them with
its own generic caching strategy. This broke Claude Code's carefully
placed cache breakpoints for plans and other features.
Changes:
- Add preserveCacheControl parameter to prepareClaudeRequest()
- Detect Claude passthrough mode (sourceFormat === targetFormat === CLAUDE)
- Skip cache_control normalization when preserveCacheControl=true
- Preserve client's cache_control markers in system, messages, and tools
This ensures Claude Code's prompt caching optimization works correctly
while maintaining OmniRoute's caching strategy for translation scenarios.

The 'Import from /models' button failed because opencode-zen was not
registered in PROVIDER_MODELS_CONFIG. The provider's API at
https://opencode.ai/zen/v1/models returns standard OpenAI-compatible
format and is now properly configured for model import.
