feat(SPEC_11): finalize transition to Sexual Health Research Specialist

This commit completes the transition of DeepBoner to a dedicated Sexual Health Research Agent by removing all references to "general" and "drug repurposing" domains. Key changes include:

- Updated domain defaults to exclusively use "sexual_health".
- Replaced all example queries and documentation to reflect a focus on sexual health topics.
- Removed any lingering references to non-sexual health concepts in code and tests.
- Ensured all tests are aligned with the new domain focus, passing successfully.

This change reinforces the project's identity and simplifies the codebase, enhancing clarity and usability for users focused on sexual health research.

Closes #89.

-# SPEC_11: Narrow Scope to Sexual Health Only
-
-## Problem Statement
-
-DeepBoner has an **identity crisis**. Despite being branded as a "pro-sexual deep research agent" (the name is literally "DeepBoner"), the codebase currently supports three domains:
-
-1. **GENERAL** - Generic research (default!)
-2. **DRUG_REPURPOSING** - Drug repurposing research
-3. **SEXUAL_HEALTH** - Sexual health research
-
-This happened because Issue #75 recommended "general purpose with domain presets", but that was the **wrong decision** for this project's identity.
-
-### Evidence of the Problem
-
-**Current examples in Gradio UI:**
-```python
-examples=[
-    ["What drugs improve female libido post-menopause?", "simple", "sexual_health", ...],
-    ["Metformin mechanism for Alzheimer's?", "simple", "general", ...],  # <-- NOT SEXUAL HEALTH!
-    ["Clinical trials for PDE5 inhibitors alternatives?", "advanced", "sexual_health", ...],
-]
-```
-
-**Default domain is "general":**
-```python
-value="general",  # <-- WRONG! Should be sexual_health
-```
-
-## The Decision
-
-**DeepBoner IS a Sexual Health Research Specialist (Option B from Issue #75)**
-
-Reasons:
-1. **Brand identity**: "DeepBoner" is unmistakably sexual health themed
-2. **Hackathon differentiation**: A focused niche beats generic competition
-3. **Prompt quality**: Domain-specific prompts are more effective
-4. **Simplicity**: Less code, less confusion
-
-## Implementation Plan
-
-### Phase 1: Simplify Domain Enum
-
-**File: `src/config/domain.py`**
-
-```python
-# BEFORE
-class ResearchDomain(str, Enum):
-    GENERAL = "general"
-    DRUG_REPURPOSING = "drug_repurposing"
-    SEXUAL_HEALTH = "sexual_health"
-
-DEFAULT_DOMAIN = ResearchDomain.GENERAL
-
-# AFTER
-class ResearchDomain(str, Enum):
-    SEXUAL_HEALTH = "sexual_health"
-
-DEFAULT_DOMAIN = ResearchDomain.SEXUAL_HEALTH
-```
-
-**Also remove:**
-- `GENERAL_CONFIG`
-- `DRUG_REPURPOSING_CONFIG`
-- Their entries in `DOMAIN_CONFIGS`
-
-### Phase 2: Update Gradio Examples
-
-**File: `src/app.py`**
-
-Replace examples with 3 sexual-health-only queries:
-
-```python
-examples=[
-    [
-        "What drugs improve female libido post-menopause?",
-        "simple",
-        "sexual_health",
-        None,
-        None,
-    ],
-    [
-        "Testosterone therapy for hypoactive sexual desire disorder?",
-        "simple",
-        "sexual_health",
-        None,
-        None,
-    ],
-    [
-        "Clinical trials for PDE5 inhibitors alternatives?",
-        "advanced",
-        "sexual_health",
-        None,
-        None,
-    ],
-],
-```
-
-### Phase 3: Simplify or Remove Domain Dropdown
-
-**Option A: Remove dropdown entirely**
-- Remove the `gr.Dropdown` for domain selection
-- Hardcode `domain="sexual_health"` in the function
-
-**Option B: Keep but simplify** (recommended for backwards compat)
-- Only show `["sexual_health"]` in choices
-- Default to `"sexual_health"`
-- Keeps the parameter in case we want to add domains later
-
-```python
-gr.Dropdown(
-    choices=["sexual_health"],  # Only one choice
-    value="sexual_health",
-    label="Research Domain",
-    info="Specialized for sexual health research",
-    visible=False,  # Hide since there's only one option
-),
-```
-
-### Phase 4: Update Tests
-
-Update domain-related tests to only test SEXUAL_HEALTH:
-
-```python
-# BEFORE
-def test_get_domain_config_general():
-    config = get_domain_config(ResearchDomain.GENERAL)
-    assert config.name == "General Research"
-
-# AFTER
-def test_get_domain_config_default():
-    config = get_domain_config()
-    assert config.name == "Sexual Health Research"
-```
-
-### Phase 5: Update Documentation
-
-- `CLAUDE.md`: Update description to focus on sexual health
-- `README.md`: Update if needed
-- Remove references to "drug repurposing" or "general" modes
-
-## Files to Modify
-
-| File | Changes |
-|------|---------|
-| `src/config/domain.py` | Remove GENERAL, DRUG_REPURPOSING; change DEFAULT_DOMAIN |
-| `src/app.py` | Update examples; simplify/hide domain dropdown |
-| `src/utils/config.py` | Change default `research_domain` field |
-| `tests/unit/config/test_domain.py` | Update to test only SEXUAL_HEALTH |
-| `tests/unit/utils/test_config_domain.py` | Update enum tests |
-| `tests/unit/test_app_domain.py` | Update to use SEXUAL_HEALTH |
-| `CLAUDE.md` | Update project description |
-
-## Example Queries (All Sexual Health)
-
-1. **Female libido**: "What drugs improve female libido post-menopause?"
-2. **Low desire**: "Testosterone therapy for hypoactive sexual desire disorder?"
-3. **ED alternatives**: "Clinical trials for PDE5 inhibitors alternatives?"
-
-Alternative options:
-- "Flibanserin mechanism of action and efficacy?"
-- "Bremelanotide for hypoactive sexual desire disorder?"
-- "PT-141 clinical trial results?"
-- "Natural supplements for erectile dysfunction?"
-
-## Success Criteria
-
-- [ ] Only `SEXUAL_HEALTH` domain exists in enum
-- [ ] Default domain is `SEXUAL_HEALTH`
-- [ ] All 3 Gradio examples are sexual health queries
-- [ ] Domain dropdown is hidden or removed
-- [ ] All tests pass with 227+ tests
-- [ ] No references to "Metformin for Alzheimer's" or "general" domain

+# SPEC_11: Sexual Health Research Specialist (Final Polish)
+
+**Status**: APPROVED
+**Priority**: P0 (Critical Fix)
+**Effort**: Low (Cleanup & Polish)
+**Related Issues**: #75, #89
+
+## 1. Executive Summary
+
+DeepBoner is **exclusively** a Sexual Health Research Agent. The codebase is currently in a transitional state where "General" and "Drug Repurposing" modes were architecturally removed, but significant artifacts (docstrings, default arguments, variable names, and examples) remain.
+
+This specification dictates the **complete eradication** of non-sexual-health concepts from the codebase to ensure a consistent, focused, and professional product identity.
+
+## 2. The Rules of Engagement
+
+1.  **No "General" Defaults**: The string literal `"general"` shall not exist as a default value for any `domain` parameter.
+2.  **No "Drug Repurposing" References**: Terms like "metformin", "alzheimer", "cancer", "aspirin" in examples must be replaced with sexual health examples.
+3.  **Single Source of Truth**: `src.config.domain.ResearchDomain.SEXUAL_HEALTH` is the *only* valid domain.
+4.  **Ironclad Tests**: Tests must use sexual health queries (e.g., "libido", "testosterone", "PDE5") to ensure the domain logic is actually exercising the production paths.
+
+## 3. Implementation Plan
+
+### 3.1. Code Cleanup (`src/`)
+
+#### `src/app.py`
+- **Logic Fix**: Change `domain_str = domain or "general"` to `domain_str = domain or "sexual_health"`.
+- **Signature Fix**: Change `domain: str = "general"` to `domain: str = "sexual_health"`.
+- **Docstring Fix**: Remove `(e.g., "general", "sexual_health")`.
+
+#### `src/mcp_tools.py`
+- **Signature Fix**: Update `search_pubmed` and `search_all_sources` to default `domain="sexual_health"`.
+- **Docstring Fix**: Update examples from "metformin alzheimer" to "testosterone libido".
+- **Argument Description**: Remove `(general, drug_repurposing, sexual_health)` list.
+
+#### `src/tools/*.py`
+- **`clinicaltrials.py`, `query_utils.py`, `tools.py`**: Replace all "metformin/alzheimer" example strings with sexual health examples.
+
+#### `src/config/domain.py`
+- **Comment Fix**: Remove `# Get default (general) config`.
+
+### 3.2. Test Suite Alignment (`tests/`)
+
+#### `tests/unit/agent_factory/test_judges.py`
+- Replace `metformin alzheimer` test queries with `sildenafil efficacy`.
+
+#### `tests/unit/tools/test_query_utils.py`
+- Ensure synonym expansion tests use relevant terms (or generic ones that don't imply a different domain).
+
+#### `tests/unit/mcp/test_mcp_tools_domain.py`
+- Verify defaults are "sexual_health", not "general".
+
+## 4. Verification Checklist
+
+- [ ] **Grep Audit**: `grep -r "general" src/` should return zero results where it refers to a domain default.
+- [ ] **Grep Audit**: `grep -r "metformin" src/` should return zero results.
+- [ ] **Functionality**: `src/app.py` runs without crashing when `domain` is `None` (defaults to sexual_health).
+- [ ] **Tests**: All 237+ tests pass.
+
+## 5. Success State
+
+When this spec is implemented, a developer reading the code should see **zero evidence** that this agent was ever intended for anything other than Sexual Health research.
