 Replace hardcoded provider-specific behavior with data-driven configuration.
 Same model, different provider → different parameters.

 **Provider Profiles**
-- [ ] `provider_profiles` JSONB column on `provider_configs` table (or separate table if schema cleaner)
-- [ ] Profile schema per provider type: defines available settings, types, defaults, validation
-- [ ] Built-in profile schemas for: openai, anthropic, venice, openrouter (others inherit openai-compatible)
-- [ ] System prompt injection: provider-specific preambles (e.g. Venice character system prompt)
-- [ ] Thinking mode toggle: per-provider `think` parameter mapping (Venice `venice_parameters.include_venice_system_prompt`, Anthropic `thinking.type=enabled`, etc.)
+- [x] Profile schema per provider type: defines available settings, types, defaults, validation, dependency rules (`providers/profile.go`)
+- [x] Built-in profile schemas for: openai, anthropic, venice, openrouter (unknown types fall back to openai-compatible)
+- [x] System prompt injection: `system_prompt_prefix` setting prepended to first system message (all providers)
+- [x] Thinking mode toggle: Anthropic `extended_thinking` + `thinking_budget` → injects `thinking.type=enabled`; Venice `enable_thinking` → disables Venice system prompt
+- [ ] _(not needed)_ `provider_profiles` JSONB column — existing `provider_configs.settings` JSONB already serves this purpose
 
 **Request/Response Transforms**
-- [ ] `PreRequestHook(providerType string, profile JSONB, req *CompletionRequest)` — decorate request before dispatch
-- [ ] `PostResponseHook(providerType string, profile JSONB, resp *StreamEvent)` — normalize provider-specific response fields
-- [ ] Hook implementations: Venice thinking extraction, Anthropic extended thinking, OpenRouter model routing headers
-- [ ] Preset-level overrides: Persona can override provider-specific settings ("always enable thinking for this Persona")
-- [ ] `ProviderConfig.Settings` fully utilized: hooks read from config, not hardcoded switch statements
+- [x] `Hooks.PreRequest(cfg, req)` — decorate request before dispatch (system prompt prefix, ExtraBody injection)
+- [x] `Hooks.PostStreamEvent(cfg, event)` — normalize provider-specific response fields (Venice thinking extraction)
+- [x] Hook implementations: Venice web search + thinking, Anthropic extended thinking + beta header, OpenRouter routing preferences + require_parameters, OpenAI frequency/presence penalty
+- [x] Preset-level overrides: `MergePresetSettings()` merges persona overrides onto provider settings, respecting `ProviderOnly` fields
+- [x] `ProviderConfig.Settings` fully utilized: hooks read from config, not hardcoded switch statements
+- [x] `CompletionRequest.ExtraBody` field + `mergeExtraBody()` for provider-specific wire fields
+- [x] Anthropic extended thinking stream support: `thinking_delta` content blocks → `Reasoning` field
 
-**Provider Type Registry** (prep for v0.22.2)
-- [ ] `providers.Init()` reads provider type → adapter mapping from registry instead of hardcoded list
-- [ ] New provider types registrable via config (openai-compatible endpoint + custom profile schema)
-- [ ] `GET /api/v1/admin/provider-types` endpoint: list available provider types with their profile schemas
+**Provider Type Registry**
+- [x] `providers.Init()` uses `RegisterType()` with full metadata (name, description, default endpoint, profile schema)
+- [x] `ProviderTypeMeta` struct: ID, name, description, default_endpoint, profile_schema
+- [x] `GET /api/v1/admin/provider-types` endpoint: list available provider types with their profile schemas
+- [ ] _(deferred → v0.22.3)_ New provider types registrable via config file (openai-compatible endpoint + custom profile schema)
+
+**Search Provider Health** (carried from v0.22.0)
+- [ ] _(deferred → v0.22.2)_ `RecordOutcome` for web_search and url_fetch tool calls
+- [ ] _(deferred → v0.22.2)_ Rate limit tracking per provider config
