fix(api): enable querying of CLI-created community corpus items

## Problem
CLI-created community corpus items (tier 3) were stored correctly but
invisible via API queries. Two issues blocked discoverability:

1. **Prefix mismatch**: API hardcoded 'community://pattern/' for
   aggregated patterns, but CLI creates 'community://rust/http/...' URIs
2. **Query parameter parsing**: Axum's default parser doesn't support
   bracket notation (?sources[]=value) used by the dashboard

Result: 0/22 CLI-created items were queryable.

## Solution

### Fix 1: Broaden Community Prefix
- Changed: 'community://pattern/' → 'community://' in corpus handler
- Impact: Now matches both aggregated patterns AND CLI-created items
- Backward compatible: Broader prefix includes narrower results

### Fix 2: Add QsQuery Extractor
- Added: serde_qs dependency + custom QsQuery extractor
- Supports: Bracket notation for array parameters (?sources[]=a&sources[]=b)
- Compatible: Works with JavaScript URLSearchParams standard
- Tested: 3 new unit tests for extractor behavior

## Verification
- ✅ All 22 CLI-created community items now queryable (was 0)
- ✅ Source filtering works: community (22), RFC (2), vendor (5)
- ✅ Multi-source queries work: ?sources[]=community&sources[]=rfc → 24
- ✅ All 89 API tests pass + 3 new extractor tests
- ✅ Clippy clean (0 warnings)
- ✅ No regressions in existing functionality

## Files Changed
- crates/stemedb-api/Cargo.toml: Add serde_qs dependency
- crates/stemedb-api/src/extractors.rs: New QsQuery extractor (117 lines)
- crates/stemedb-api/src/handlers/aphoria/corpus.rs: Use QsQuery, broaden prefix
- crates/stemedb-api/src/lib.rs: Export extractors module

Also includes: Scale-adaptive thresholds, wiki corpus extraction,
documentation updates, and dashboard UI improvements from prior work.

+
+The repository includes automatic git hooks to rebuild binaries when source code changes:
+
+- **post-merge**: Runs after `git pull` or `git merge`
+- **post-checkout**: Runs after `git checkout` (branch switches only)
+
+These hooks detect changes to:
+- Aphoria CLI and core logic
+- StemeDB API server
+- StemeDB simulator
+- Core libraries (affects all binaries)
+
+When changes are detected, the hooks automatically run `cargo build --release --workspace` to rebuild all binaries. This prevents "command not found" errors from stale binaries.
+
+The hooks are installed in `.git/hooks/` and are already executable. If you need to disable them temporarily, you can use `--no-verify` with git commands or rename the hook files.

+
+# Wiki Corpus Extraction Skill
+
+## Identity
+
+You are an intelligent claim extraction engine that reads technical documentation and extracts factual, verifiable claims for the Aphoria knowledge corpus.
+
+Your job is to:
+1. Read wiki markdown files
+2. Extract factual claims using LLM reasoning
+3. Generate CLI commands to persist claims in the corpus database
+4. Report comprehensive results with success/failure breakdown
+
+## Core Principles
+
+1. **Factual over Normative**: Extract what IS (not what SHOULD BE)
+2. **Context-Aware Authority**: Infer sources from GitHub URLs, paper citations, official docs
+3. **Hierarchical Subjects**: Build semantic paths (ml/dependencies/basicsr/version)
+4. **Intelligent Chunking**: Break at headings when possible, ~4K token chunks
+5. **Batch Processing**: Extract all claims, then execute CLI commands
+6. **Bundle Errors**: Collect all errors and report them together
+
+## Workflow Overview
+
+```
+Phase 1: Discover & Read
+    ↓
+Phase 1.2: Verify Commands
+    ↓
+Phase 2: Intelligent Chunking
+    ↓
+Phase 3: Claim Extraction (Per Chunk)
+    ↓
+Phase 4: Validation
+    ↓
+Phase 5: CLI Execution
+    ↓
+Phase 6: Summary Report
+```
+
+---
+
+## Phase 1: Discover & Read
+
+### Step 1.1: Check Input
+
+- If file passed via CLI args: use that file
+- If directory passed: walk to find all `.md` files
+- Use Read tool to get full content of each file
+
+### Step 1.2: Verify Aphoria Binary and Commands
+
+Before proceeding, verify that the required commands exist:
+
+```bash
+# Check Aphoria version
+aphoria --version
+
+# Verify corpus create command exists
+if ! aphoria corpus --help 2>&1 | grep -q "create"; then
+    echo "❌ ERROR: 'aphoria corpus create' command not available"
+    echo ""
+    echo "This suggests the aphoria binary is out of date."
+    echo ""
+    echo "Fix options:"
+    echo "  1. Rebuild: cargo build --release -p aphoria"
+    echo "  2. Check git status: git status"
+    echo "  3. Pull latest: git pull && cargo build --release -p aphoria"
+    echo ""
+    exit 1
+fi
+
+echo "✅ Aphoria binary up to date (corpus create available)"
+```
+
+**Decision Gate:** Command exists? → Proceed to token estimation
+
+### Step 1.3: Estimate Token Count
+
+Rough estimate: **1 token ≈ 4 characters**
+
+```
+token_count = len(content) / 4
+```
+
+If `token_count > 4000`, proceed to Phase 2 (chunking).
+If `token_count <= 4000`, treat as single chunk.
+
+---
+
+## Phase 2: Intelligent Chunking
+
+### Goal
+Split content into ~4K token chunks, preferring heading boundaries.
+
+### Algorithm
+
+1. **Try splitting on `## ` (level 2 headings)**
+   - Sections should be roughly 4K tokens each
+   - If a section is still > 4K, split on `### ` (level 3 headings)
+
+2. **Include context in each chunk**
+   - Document title (from `# ` heading)
+   - Section path (breadcrumb of headings)
+   - Example: "Document: ML Dependencies Guide / Section: Critical Compatibility Solutions / Subsection: BasicSR Fix"
+
+3. **Maintain overlap**
+   - Include previous heading for context
+   - This helps LLM understand relationships
+
+### Chunk Metadata Format
+
+```json
+{
+  "chunk_id": 1,
+  "total_chunks": 3,
+  "document_title": "ML Dependencies Guide",
+  "section_path": "Critical Compatibility Solutions / BasicSR Fix",
+  "content": "..."
+}
+```
+
+---
+
+## Phase 3: Claim Extraction (Per Chunk)
+
+### Prompt the LLM
+
+For each chunk, use a structured extraction prompt:
+
+````
+You are extracting factual claims from technical documentation for a knowledge corpus.
+
+**Context:**
+- Document: {document_title}
+- Section: {section_path}
+- Chunk: {chunk_id}/{total_chunks}
+
+**Content:**
+{chunk_content}
+
+**Task:**
+Extract all factual claims as JSON array. Each claim must be:
+1. Factual (not opinion or speculation)
+2. Verifiable from the text
+3. Useful for developers
+
+**Authority Inference Rules:**
+- GitHub URLs/commits → "Repository/Project@hash"
+- Research papers → "Author et al. (Year)"
+- Official documentation → "Project Documentation"
+- Empirical observation → "Community consensus"
+
+**Tier Assignment:**
+- 0: RFC, W3C spec, ISO standard (regulatory)
+- 1: OWASP, CWE, security advisory (clinical)
+- 2: Project docs, compatibility notes (observational)
+- 3: Blog posts, forum consensus (community)
+
+**Output Format:**
+```json
+[
+  {
+    "subject": "hierarchical/path/to/concept",
+    "predicate": "relationship_type",
+    "value": "constraint_or_value",
+    "explanation": "full sentence with context",
+    "authority": "inferred_source",
+    "category": "compatibility|performance|security|architecture|quality",
+    "confidence": 0.95,
+    "tier": 2
+  }
+]
+```
+
+Return ONLY the JSON array, no additional text.
+````
+
+### Expected Output Structure
+
+```json
+[
+  {
+    "subject": "ml/dependencies/basicsr/torchvision",
+    "predicate": "incompatible_with",
+    "value": ">=0.15",
+    "explanation": "basicsr 1.4.2 imports from torchvision.transforms.functional_tensor which was removed in torchvision 0.15+",
+    "authority": "XPixelGroup/BasicSR GitHub",
+    "category": "compatibility",
+    "confidence": 0.95,
+    "tier": 2
+  }
+]
+```
+
+---
+
+## Phase 4: Validation
+
+### Step 4.1: Filter by Confidence
+
+Only keep claims where `confidence >= 0.7`
+
+### Step 4.2: Check Required Fields
+
+Each claim must have:
+- `subject` (non-empty string)
+- `predicate` (non-empty string)
+- `value` (any type)
+- `explanation` (non-empty string)
+- `authority` (non-empty string)
+- `category` (one of: compatibility, performance, security, architecture, quality)
+- `tier` (0-3)
+
+### Step 4.3: Validate Tier
+
+Tier must be 0, 1, 2, or 3. If invalid, record error and skip claim.
+
+### Step 4.4: Check for Duplicates
+
+**Important**: The corpus database is **append-only**. Multiple sources can create the same `subject+predicate` pair. This is **allowed and expected**. Do NOT filter duplicates — just warn about them in the report.
+
+---
+
+## Phase 5: CLI Execution
+
+### Step 5.1: Construct CLI Commands
+
+For each validated claim, construct:
+
+```bash
+aphoria corpus create \
+  --subject "{subject}" \
+  --predicate "{predicate}" \
+  --value "{value}" \
+  --explanation "{explanation}" \
+  --authority "{authority}" \
+  --category "{category}" \
+  --tier {tier}
+```
+
+**Important**: Use proper shell escaping for strings with quotes or special characters.
+
+### Step 5.2: Execute Commands
+
+Use the Bash tool to execute each command.
+
+### Step 5.3: Collect Results
+
+For each execution:
+- **Success**: Record the corpus ID (e.g., "corpus://ml/foo/bar/predicate")
+- **Failure**: Record the full error message
+
+---
+
+## Phase 6: Summary Report
+
+### Report Structure
+
+```markdown
+# Wiki Corpus Extraction Report
+
+**File:** /path/to/wiki/article.md
+**Chunks Processed:** 3
+**Claims Extracted:** 23
+**Claims Stored:** 20
+**Errors:** 3
+
+## Stored Claims
+
+| Subject | Predicate | Value | Authority | Tier |
+|---------|-----------|-------|-----------|------|
+| ml/basicsr/torchvision | incompatible_with | >=0.15 | XPixelGroup/BasicSR | 2 |
+| ... | ... | ... | ... | ... |
+
+## Errors
+
+### Validation Errors (2)
+
+1. **ml/foo/bar** - Invalid tier '5' (must be 0-3)
+2. **api/rest/foo** - Missing explanation field
+
+### Storage Errors (1)
+
+1. **net/http/timeout** - Database write failed: connection refused
+
+## Next Steps
+
+View corpus items: http://localhost:3000/corpus
+Query API: curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=community&limit=100'
+```
+
+---
+
+## Predicate Naming Conventions
+
+Use consistent predicate names to enable effective querying:
+
+| Relationship | Predicate |
+|--------------|-----------|
+| Version constraint | `requires`, `incompatible_with`, `compatible_with` |
+| Recommendation | `recommends`, `discourages` |
+| Performance | `faster_than`, `slower_than`, `optimal_for` |
+| Security | `vulnerable_to`, `mitigates`, `exposes` |
+| Configuration | `default_value`, `max_value`, `required_for` |
+
+---
+
+## Subject Path Guidelines
+
+Build hierarchical paths that reflect the domain structure:
+
+### Examples
+
+- `ml/dependencies/{package}/{aspect}`
+  - Example: `ml/dependencies/basicsr/torchvision`
+- `api/{protocol}/{feature}`
+  - Example: `api/rest/authentication`
+- `security/{category}/{vuln_type}`
+  - Example: `security/input-validation/xss`
+- `performance/{component}/{metric}`
+  - Example: `performance/database/connection-pool`
+
+### Principles
+
+- Start general, get specific
+- Use lowercase with forward slashes
+- Use hyphens for multi-word segments
+- Keep paths under 6-7 levels
+
+---
+
+## Category Guidelines
+
+Choose the most appropriate category:
+
+| Category | Use When |
+|----------|----------|
+| `compatibility` | Version constraints, breaking changes, API compatibility |
+| `performance` | Optimization, resource usage, latency, throughput |
+| `security` | Vulnerabilities, mitigations, attack vectors |
+| `architecture` | Design patterns, module structure, dependencies |
+| `quality` | Code quality, maintainability, best practices |
+
+---
+
+## Authority Tier Guidelines
+
+| Tier | Name | Examples | When to Use |
+|------|------|----------|-------------|
+| 0 | Regulatory | RFC 7231, W3C spec, ISO 27001 | Official standards bodies |
+| 1 | Clinical | OWASP Top 10, CWE-79, NVD | Security advisories, vulnerability databases |
+| 2 | Observational | PyTorch docs, GitHub project READMEs | Official project documentation |
+| 3 | Community | Blog posts, Stack Overflow, forum threads | Community wisdom, empirical observations |
+
+---
+
+## Error Handling
+
+### Validation Errors
+
+Collect all validation errors and report them together. Do NOT stop on the first error.
+
+Example validation errors:
+- Invalid tier (not 0-3)
+- Missing required field
+- Confidence below threshold (< 0.7)
+
+### Storage Errors
+
+If a CLI command fails:
+- Capture the full error message
+- Continue with remaining commands
+- Report all failures at the end
+
+### LLM Extraction Errors
+
+If the LLM returns invalid JSON:
+- Log the chunk that failed
+- Continue with remaining chunks
+- Report the parsing error in summary
+
+---
+
+## Do's and Don'ts
+
+### Do
+
+- ✅ Extract factual claims (not opinions)
+- ✅ Verify command availability before execution
+- ✅ Infer authority from context
+- ✅ Generate semantic subject paths
+- ✅ Include full explanation context
+- ✅ Bundle errors for batch reporting
+- ✅ Use Read tool to get file content
+- ✅ Use Bash tool to execute CLI commands
+- ✅ Filter by confidence >= 0.7
+- ✅ Allow duplicate subject+predicate (append-only DB)
+
+### Do Not
+
+- ❌ Extract opinions or speculative claims
+- ❌ Assume binary is up to date
+- ❌ Lose source attribution
+- ❌ Hardcode authority (infer from content)
+- ❌ Stop on first error (collect all errors)
+- ❌ Modify files (read-only skill)
+- ❌ Use placeholder values
+- ❌ Skip validation
+- ❌ Filter duplicates (append-only allows them)
+

+
+## Example Extraction
+
+### Input Text
+
+```markdown
+## BasicSR and Torchvision Compatibility
+
+The BasicSR library (v1.4.2) has a critical compatibility issue with torchvision >= 0.15.
+The library imports from `torchvision.transforms.functional_tensor`, which was removed
+in torchvision 0.15+.
+
+Source: https://github.com/XPixelGroup/BasicSR/issues/123
+
+Recommended workaround: Pin torchvision to 0.14.1 or earlier.
+```
+
+### Extracted Claims

+  {
+    "subject": "ml/dependencies/basicsr/torchvision",
+    "predicate": "incompatible_with",

+- **aphoria-suggest**: Suggest claims from existing patterns
+- **aphoria-claims**: Author claims from diffs
+
+---
+
+## Implementation Notes
+
+### Token Counting
+
+Use rough heuristic: `token_count = len(content) / 4`
+
+This is approximate but good enough for chunking decisions.
+
+### Shell Escaping
+
+When constructing CLI commands, properly escape strings:
+
+```python
+import shlex
+
+escaped_explanation = shlex.quote(explanation)
+```
+
+Or in bash:
+```bash
+explanation="${explanation//\"/\\\"}"  # Escape quotes
+```
+
+### Confidence Threshold
+
+Only extract claims with `confidence >= 0.7`. This filters out:
+- Speculative statements
+- Uncertain inferences
+- Low-quality extractions
+
+### Append-Only Semantics
+
+The corpus database is append-only. Multiple sources can contribute claims for the same `subject+predicate`. This enables:
+- Cross-validation from multiple sources
+- Community consensus building
+- Evolving knowledge over time
+
+Do NOT filter duplicates. Just warn about them in the report.
+
+---
+
+## Success Criteria
+
+A successful extraction should:
+
+1. ✅ Read all markdown files in the input directory
+2. ✅ Extract factual claims with proper structure
+3. ✅ Infer authority from context (GitHub URLs, docs, etc.)
+4. ✅ Assign appropriate tiers (0-3)
+5. ✅ Execute CLI commands successfully
+6. ✅ Report comprehensive summary with errors bundled
+7. ✅ Handle validation errors gracefully
+8. ✅ Handle storage errors gracefully
+9. ✅ Generate semantic subject paths
+10. ✅ Use consistent predicate naming
+
+---
+
+## Troubleshooting
+
+### "Command not found" or "unrecognized subcommand 'create'" Errors
+
+If you see `error: unrecognized subcommand 'create'` or similar errors:
+
+**Diagnosis:**
+1. **Check binary date**: `ls -lh target/release/aphoria`
+2. **Check CLI code date**: `ls -lh applications/aphoria/src/cli/mod.rs`
+3. **If CLI is newer**: The binary is out of date
+
+**Solutions:**
+```bash
+# Option 1: Rebuild the binary
+cargo build --release -p aphoria
+
+# Option 2: Pull latest changes and rebuild
+git pull && cargo build --release -p aphoria
+
+# Option 3: Check if there are uncommitted changes
+git status
+```
+
+**Prevention:**
+See Fix #1 for setting up git hooks that automatically rebuild binaries on pull.
+
+### "Database already open" error
+
+The corpus database at `~/.aphoria/corpus-db` is locked by another process (probably the API server).
+
+**Solution**: Stop the API server temporarily:
+```bash
+pkill -f stemedb-api
+```
+
+### "Invalid tier" error
+
+Tier must be 0, 1, 2, or 3.
+
+**Solution**: Review tier assignment rules and fix the extracted tier value.
+
+### "Missing required field" error
+
+All claims must have: subject, predicate, value, explanation, authority, category, tier.
+
+**Solution**: Review the LLM extraction prompt and ensure all fields are present.
+
+### LLM returns invalid JSON
+
+The LLM might return markdown formatting or extra text.
+
+**Solution**: Update the extraction prompt to be more explicit about returning ONLY the JSON array.

+- **Import CLI:** `aphoria corpus import wiki <path>`
+- **API Config:** Set `STEMEDB_DB_DIR` to choose database
+
+## Troubleshooting
+
+**Dashboard shows empty results?**
+- Check API is running on port 18180
+- Verify API is using corpus database: `ps aux | grep stemedb-api`
+- Check API logs for database path
+
+**API won't start?**
+- Make sure corpus DB exists: `ls ~/.aphoria/corpus-db/`
+- Check port not in use: `lsof -i :18180`
+- View logs: `tail -f /tmp/api-corpus.log`
+
+**Need to reimport wiki?**
+```bash
+rm -rf ~/.aphoria/corpus-db
+target/release/aphoria corpus import wiki <path>

+# Documentation Audit Summary: Corpus Endpoint & Multi-Project Architecture
+
+**Date:** 2026-02-09
+**Trigger:** Implemented Phase 1-3 (corpus endpoint, per-project databases, corpus database)
+**Files Analyzed:** 39 markdown files, 12,104 total lines
+
+---
+
+## Changes Implemented
+
+### Code Changes (Already Complete)
+- ✅ Phase 1: `/v1/aphoria/corpus` endpoint (returns RFC/OWASP/Community best practices)
+- ✅ Phase 2: Per-project database default (`.aphoria/db` instead of `~/.aphoria/db`)
+- ✅ Phase 3: Corpus database architecture (`~/.aphoria/corpus-db` for aggregated patterns)
+
+### Documentation Updates (This Session)
+
+#### UPDATED Files
+
+1. **`guides/the-first-scan.md:45`** ✅
+   - **Before:** `~/.aphoria/db` (stale path)
+   - **After:** `.aphoria/db` + note about override for shared mode
+   - **Impact:** Users no longer misled about default database location
+
+2. **`cli-reference.md`** ✅
+   - **Added:** Database architecture explanation in `aphoria init` section
+   - **Added:** Configuration section at end with quick example
+   - **Added:** Link to new `configuration.md`
+   - **Impact:** Users can discover configuration options
+
+#### CREATED Files
+
+3. **`configuration.md`** ✅ (NEW - 397 lines)
+   - **Purpose:** Complete `aphoria.toml` reference
+   - **Sections:**
+     - Database configuration (per-project vs shared)
+     - All config sections with examples
+     - Environment variables
+     - Migration guide from legacy home-based database
+   - **Impact:** Canonical configuration documentation
+
+---
+
+## Issues Found
+
+### High Priority (Fixed)
+- ✅ **Stale database path** in `the-first-scan.md` - Fixed
+- ✅ **Missing configuration docs** - Created `configuration.md`
+- ✅ **No CLI reference link to config** - Added
+
+### Medium Priority (Deferred)
+- ⚠️ **Dashboard references** (6 mentions in `phase-17-summary.md`)
+  - **Status:** Dashboard exists but not documented as user-facing feature
+  - **Decision Needed:** Is dashboard production-ready for user docs?
+  - **Recommendation:** Add to CLI reference when ready, or mark as "internal/beta"
+
+- ⚠️ **Multi-project architecture guide** (not created yet)
+  - **Status:** Configuration explains database paths, but no dedicated architecture guide
+  - **Decision Needed:** Is a separate guide needed, or is `configuration.md` sufficient?
+  - **Recommendation:** Defer until users ask for it (YAGNI)
+
+### Low Priority (No Action)
+- **No stale planning docs found** - All planning docs appear current or properly archived
+- **No duplicate content detected** - "Claims vs Observations" appears once (README.md)
+- **No old terminology** - No references to deprecated terms found
+
+---
+
+## Verification
+
+### Examples Tested
+✅ All bash examples in updated docs tested:
+```bash
+aphoria init           # ✓ Creates .aphoria/db/ by default
+aphoria scan .         # ✓ Works
+aphoria claims create  # ✓ Works
+```
+
+### Cross-Links Verified
+✅ All new cross-links resolve:
+- `cli-reference.md` → `configuration.md` ✓
+- `the-first-scan.md` references correct path ✓
+- `configuration.md` → `cli-reference.md`, `scale-adaptive-thresholds.md`, etc. ✓
+
+### Terminology Check
+✅ No old terminology found:
+```bash
+! grep -r "~/.aphoria/db" applications/aphoria/docs/guides/*.md
+# Only 1 reference in the-first-scan.md (correctly documented as override)
+```
+
+---
+
+## Files Modified
+
+### Updated (3 files)
+1. `applications/aphoria/docs/guides/the-first-scan.md` (+2 lines)
+2. `applications/aphoria/docs/cli-reference.md` (+19 lines)
+
+### Created (2 files)
+3. `applications/aphoria/docs/configuration.md` (+397 lines, NEW)
+4. `applications/aphoria/docs/DOC-UPDATE-2026-02-09.md` (audit plan, reference only)
+
+### Total Impact
+- **Lines added:** 418 lines
+- **Stale references fixed:** 1
+- **New canonical documentation:** 1 (configuration.md)
+
+---
+
+## Outstanding Decisions
+
+### 1. Dashboard Documentation
+
+**Question:** Should we create `guides/dashboard-setup.md`?
+
+**Options:**
+- **A. Yes** - If dashboard is user-facing and production-ready
+- **B. Add brief section to CLI reference** - If dashboard is beta/internal
+- **C. No** - If dashboard is for developers only
+
+**Current State:** Dashboard is mentioned in implementation docs but not user guides.
+
+**Recommendation:** Option B - Add brief section to CLI reference:
+```markdown
+## Dashboard (Beta)
+
+Start the Aphoria dashboard:
+```bash
+cd applications/aphoria-dashboard
+npm install
+npm run dev
+```
+
+**Note:** Dashboard is in beta. For production use, query via API.
+```
+
+### 2. Multi-Project Architecture Guide
+
+**Question:** Do we need a dedicated guide explaining dual-database architecture?
+
+**Options:**
+- **A. Yes** - Create `guides/multi-project-architecture.md`
+- **B. No** - `configuration.md` already explains database paths
+
+**Current State:** Configuration guide covers database paths with examples.
+
+**Recommendation:** Option B (YAGNI) - Only create if users request it. Current docs are sufficient.
+
+### 3. Migration Guide
+
+**Question:** Do we need a migration guide for upgrading from old `~/.aphoria/db`?
+
+**Options:**
+- **A. Yes** - Create migration guide
+- **B. No** - Users can override via config
+
+**Current State:** `configuration.md` includes "Migration Guide" section explaining override.
+
+**Recommendation:** Option B - Current approach (override via config) is simple and documented.
+
+---
+
+## Quality Metrics
+
+### Before
+- Stale references: 1 (database path in `the-first-scan.md`)
+- Configuration coverage: Partial (scattered across CLI reference)
+- Cross-references: Some broken (config not documented)
+
+### After
+- Stale references: 0 ✅
+- Configuration coverage: Complete (dedicated `configuration.md`) ✅
+- Cross-references: All working ✅
+
+### Coverage
+- Database architecture: **100%** (configuration.md, cli-reference.md, the-first-scan.md)
+- Corpus endpoint: **0%** (API-only, not user-facing yet)
+- Multi-project workflows: **50%** (config explains, no workflow guide)
+
+---
+
+## Next Steps
+
+### Immediate (Complete)
+- ✅ Fix stale database path
+- ✅ Create configuration reference
+- ✅ Update CLI reference with config section
+
+### Follow-Up (When Dashboard Ready)
+- [ ] Decide on dashboard documentation strategy (user-facing vs internal)
+- [ ] Add dashboard section to CLI reference (if beta) or create guide (if production)
+
+### Future (As Needed)
+- [ ] Consider `guides/multi-project-architecture.md` if users request workflow examples
+- [ ] Update when `/v1/aphoria/corpus` becomes user-facing (CLI wrapper or dashboard integration)
+
+---
+
+## Testing Checklist
+
+Completed:
+- ✅ All bash examples tested and working
+- ✅ Cross-links verified (configuration.md ↔ cli-reference.md)
+- ✅ No old terminology (`~/.aphoria/db` only mentioned as override)
+- ✅ Examples match current CLI output
+- ✅ Configuration options match code (verified against `config/defaults.rs`)
+
+---
+
+## Conclusion
+
+**Documentation is now aligned with Phase 1-3 implementation.**
+
+Key improvements:
+1. ✅ Stale database path fixed (users won't be confused)
+2. ✅ Complete configuration reference created (canonical source)
+3. ✅ CLI reference updated to guide users to config docs
+
+**No regressions detected:**
+- All existing docs still accurate
+- No broken cross-links introduced
+- No old terminology found
+
+**Outstanding work is low-priority:**
+- Dashboard docs (when ready)
+- Multi-project architecture guide (if requested)
+
+The documentation now correctly reflects the new per-project database architecture and provides clear guidance for users who need to customize it.

+# Documentation Update: Corpus Endpoint & Multi-Project Architecture
+
+**Date:** 2026-02-09
+**Scope:** Align docs with Phase 1-3 implementation (corpus endpoint, per-project databases, corpus database)
+
+---
+
+## Changes Implemented (Code)
+
+### Phase 1: Dashboard Corpus Endpoint ✅
+- **New endpoint:** `/v1/aphoria/corpus` (replaces `/v1/aphoria/patterns` for valuable content)
+- **DTOs:** `CorpusItemDto`, `GetCorpusRequest`, `GetCorpusResponse`
+- **Purpose:** Return RFC/OWASP/Community best practices instead of statistical aggregates
+
+### Phase 2: Per-Project Database Configuration ✅
+- **Old default:** `~/.aphoria/db` (home-based, shared across all projects)
+- **New default:** `.aphoria/db` (project-local, isolated per-project)
+- **Override:** Users can set `[episteme] data_dir = "~/.aphoria/db"` for shared mode
+
+### Phase 3: Corpus Database Architecture ✅
+- **New field:** `EpistemeConfig.corpus_data_dir`
+- **Default:** `~/.aphoria/corpus-db` (home-based, shared across projects)
+- **Purpose:** Aggregated pattern data from multiple projects for community corpus building
+
+---
+
+## Documentation Issues Found
+
+### 1. Stale Database Path Reference ❌
+
+**File:** `applications/aphoria/docs/guides/the-first-scan.md:45`
+
+**Current (WRONG):**
+```markdown
+This downloads strict security requirements (RFC 7519 for JWT, RFC 5246 for TLS, etc.) into your local database (`~/.aphoria/db`).
+```
+
+**Problem:** References old home-based path. Default is now `.aphoria/db` (project-local).
+
+**Fix Required:**
+```markdown
+This downloads strict security requirements (RFC 7519 for JWT, RFC 5246 for TLS, etc.) into your project database (`.aphoria/db`).
+
+> **Note:** By default, each project has its own isolated database. To share a database across all projects on your machine, set `data_dir = "~/.aphoria/db"` in `aphoria.toml`.
+```
+
+---
+
+### 2. Missing Corpus Architecture Documentation ❌
+
+**Issue:** No documentation explaining:
+- Per-project databases (observations)
+- Shared corpus database (aggregated patterns)
+- How community learning works across projects
+- The `/v1/aphoria/corpus` endpoint
+
+**Action Required:** Create new guide: `applications/aphoria/docs/guides/multi-project-architecture.md`
+
+**Outline:**
+```markdown
+# Multi-Project Architecture
+
+## Overview
+Aphoria now uses a dual-database architecture:
+- **Per-project databases** (`.aphoria/db/`) - Store observations from each project
+- **Shared corpus database** (`~/.aphoria/corpus-db/`) - Aggregate patterns across projects
+
+## Per-Project Isolation
+
+Each project gets its own database:
+```
+~/projects/
+├── maxwell/
+│   └── .aphoria/db/        # Maxwell's observations
+├── billing-api/
+│   └── .aphoria/db/        # Billing API's observations
+└── frontend/
+    └── .aphoria/db/        # Frontend's observations
+```
+
+## Community Corpus Building
+
+When you run `aphoria scan --persist --sync`:
+1. Observations are written to your project database (`.aphoria/db/`)
+2. Pattern aggregates are pushed to the corpus database (`~/.aphoria/corpus-db/`)
+3. Patterns with 95%+ adoption + authority backing auto-promote to corpus
+
+The corpus database accumulates patterns from all your projects on this machine.
+
+## Configuration
+
+**Default (per-project isolation):**
+```toml
+# .aphoria/config.toml (default)
+[episteme]
+# data_dir defaults to ./.aphoria/db (project-local)
+# corpus_data_dir defaults to ~/.aphoria/corpus-db (shared)
+```
+
+**Shared mode (legacy behavior):**
+```toml
+[episteme]
+data_dir = "~/.aphoria/db"  # All projects share one database
+```
+
+## API Endpoints
+
+For hosted/dashboard mode:
+- `/v1/aphoria/corpus` - Query RFC/OWASP/Community best practices
+- `/v1/aphoria/patterns` - Query statistical pattern aggregates (project counts)
+```
+
+---
+
+### 3. Dashboard References (Stale/Future) ⚠️
+
+**Files:**
+- `applications/aphoria/docs/phase-17-summary.md` - References "dashboard" 6 times
+- `applications/aphoria/docs/scale-adaptive-thresholds.md:163` - "empty dashboard"
+
+**Issue:** These docs reference a dashboard that exists but isn't documented as a user-facing feature yet.
+
+**Action:**
+- **If dashboard is user-facing:** Create `applications/aphoria/docs/guides/dashboard-setup.md`
+- **If dashboard is internal only:** Add note to phase-17 that dashboard is "not yet production-ready"
+
+**Recommendation:** Dashboard is mentioned in implementation docs but not in user guides. Add to CLI reference:
+
+```markdown
+## Dashboard (Beta)
+
+Start the Aphoria dashboard:
+```bash
+cd applications/aphoria-dashboard
+npm install
+npm run dev
+```
+
+Navigate to `http://localhost:3000` to view:
+- Scan results
+- Corpus items (RFC/OWASP/Community)
+- Claims coverage
+
+**Note:** Dashboard is in beta. For production use, query via API (`/v1/aphoria/*`).
+```
+
+---
+
+### 4. Configuration Guide Missing ❌
+
+**Issue:** No comprehensive configuration reference showing all `aphoria.toml` options.
+
+**Action Required:** Create `applications/aphoria/docs/configuration.md`
+
+**Outline:**
+```markdown

+```
+
+## Key Settings
+
+### Database Paths
+
+**Per-project (default):**
+```toml
+[episteme]
+data_dir = ".aphoria/db"
+```
+
+**Shared (legacy):**
+```toml
+[episteme]
+data_dir = "~/.aphoria/db"
+```
+
+**Corpus database:**
+```toml
+[episteme]
+corpus_data_dir = "~/.aphoria/corpus-db"  # Default
+# Or disable: corpus_data_dir = null
+```
+
+### Thresholds
+
+**Scale-Adaptive (default):**
+```toml
+[corpus]
+use_legacy_thresholds = false
+```
+
+Auto-detects team size (Micro: 1-5 projects → Enterprise: 501+) and adjusts promotion thresholds accordingly.
+
+**Legacy (fixed thresholds):**
+```toml
+[corpus]
+use_legacy_thresholds = true
+```
+
+See [scale-adaptive-thresholds.md](scale-adaptive-thresholds.md) for details.
+```
+

+
+## Summary of Required Changes
+
+### DELETE
+- None (no stale planning docs found related to this change)
+
+### UPDATE
+1. **`the-first-scan.md:45`** - Change `~/.aphoria/db` → `.aphoria/db` + add override note
+2. **`README.md:39`** - Add note about per-project databases (optional, keep lean)

+
+---
+
+## Testing Checklist
+
+Before committing:
+
+- [ ] All bash examples tested and working
+- [ ] Cross-links verified (configuration.md ↔ cli-reference.md ↔ guides/)
+- [ ] No old terminology (`~/.aphoria/db` as default)
+- [ ] Examples match current CLI output
+- [ ] Dashboard references accurate (production vs beta)
+
+---
+
+## Questions for User
+
+1. **Dashboard Status:** Is the Aphoria dashboard ready for user-facing docs, or should it remain "internal/beta" for now?
+
+2. **Corpus Database:** Should we document how to disable corpus aggregation (`corpus_data_dir = null`), or is it always-on?
+
+3. **Migration Guide:** Do we need a migration guide for users upgrading from old `~/.aphoria/db` to new per-project databases?
+   - **Recommendation:** Not needed. Old users can override to `data_dir = "~/.aphoria/db"` for legacy behavior.

+# Aphoria Configuration Reference
+
+Complete reference for `aphoria.toml` configuration options.
+
+---
+
+## File Location
+
+`.aphoria/config.toml` - Created by `aphoria init` in your project root.
+
+---
+
+## Quick Start
+
+**Minimal configuration (defaults work for most projects):**
+```toml
+[project]
+name = "my-project"
+```
+
+That's it! Aphoria uses sensible defaults for everything else.
+
+---
+
+## Database Configuration
+
+### Per-Project Databases (Default)
+
+**New in 2026-02-09:** Each project now has its own isolated database by default.
+
+```toml
+[episteme]
+# Project database (observations from this project)
+# Default: .aphoria/db (project-local)
+data_dir = ".aphoria/db"
+
+# Corpus database (aggregated patterns across all projects)
+# Default: ~/.aphoria/corpus-db (home-based, shared)
+corpus_data_dir = "~/.aphoria/corpus-db"
+```
+
+**Architecture:**
+```
+~/projects/
+├── maxwell/
+│   └── .aphoria/db/        # Maxwell's observations
+├── billing-api/
+│   └── .aphoria/db/        # Billing API's observations
+└── ~/.aphoria/
+    └── corpus-db/          # Shared corpus (all projects)
+```
+
+### Legacy Shared Mode
+
+To use the old behavior (single shared database for all projects):
+
+```toml
+[episteme]
+data_dir = "~/.aphoria/db"
+```
+
+### Disable Corpus Aggregation
+
+To disable cross-project pattern aggregation:
+
+```toml

+
+## Key Sections
+
+### Project
+
+Basic project metadata.
+
+```toml
+[project]
+name = "my-project"       # Optional: auto-detected from directory name
+language = "rust"          # Optional: auto-detected from file extensions
+```
+
+### Episteme
+
+Database and storage configuration.
+
+```toml
+[episteme]
+data_dir = ".aphoria/db"              # Per-project observations
+corpus_data_dir = "~/.aphoria/corpus-db"  # Shared corpus (optional)
+url = null                            # Remote Episteme (future)
+```
+
+**Key Options:**
+- `data_dir` - Where to store this project's observations
+  - Default: `.aphoria/db` (project-local)
+  - Override to `~/.aphoria/db` for legacy shared mode
+- `corpus_data_dir` - Where to store aggregated patterns
+  - Default: `~/.aphoria/corpus-db` (home-based, shared)
+  - Set to `null` to disable cross-project aggregation
+
+### Thresholds
+
+Conflict severity thresholds.
+
+```toml
+[thresholds]
+block = 0.7  # High severity (blocks CI)
+flag = 0.4   # Medium severity (warns)
+```
+
+Conflict scores range from 0.0 (no conflict) to 1.0 (total conflict).
+
+### Extractors
+
+Control which extractors run.
+
+```toml
+[extractors]
+enabled = ["tls_verify", "jwt_config", ...]
+disabled = []
+```
+
+See [cli-reference.md](cli-reference.md) for the full list of 42 available extractors.
+
+### Scan
+
+Control which files are scanned.
+
+```toml
+[scan]
+exclude = ["target/", "node_modules/"]
+max_file_size = 1_048_576  # 1MB
+include_tests = false
+```
+
+You can also use `.aphoriaignore` files (gitignore syntax).
+
+### Corpus
+
+Control corpus building and thresholds.
+
+```toml
+[corpus]
+include_rfc = true
+include_owasp = true
+include_vendor = true
+use_community = true
+aggregation_enabled = true
+use_legacy_thresholds = false  # Use adaptive thresholds
+```
+
+**Scale-Adaptive Thresholds (default):**
+
+Automatically adjusts promotion thresholds based on team size:
+- Micro (1-5 projects): Patterns visible with 2/3 adoption
+- Small (6-25 projects): Patterns visible with 5+ projects
+- Enterprise (501+): Unchanged behavior
+
+See [scale-adaptive-thresholds.md](scale-adaptive-thresholds.md) for details.
+
+**Legacy Thresholds:**
+
+```toml
+[corpus]
+use_legacy_thresholds = true
+```
+
+Fixed thresholds regardless of team size (old behavior).
+
+### Hosted Mode
+
+For team collaboration and pattern sharing.
+
+```toml
+[hosted]
+url = "https://aphoria.example.com"
+project_id = "billing-api"
+team_id = "platform-team"
+sync_mode = "push_only"
+```
+
+Requires hosted Aphoria server (future feature).
+
+### Community Sharing
+
+**CRITICAL:** Opt-in only. Anonymous pattern contribution.
+
+```toml
+[community]
+enabled = false  # Must explicitly opt-in
+anonymize = true # Project names are wildcarded
+```
+
+When enabled with `--sync`, observations are anonymized and shared with the community corpus.
+
+**Privacy Guarantees:**
+- Project names are wildcarded in paths
+- No file paths, line numbers, or source code
+- Only pattern aggregates (subject + predicate + value)
+
+### LLM Extraction
+
+Use LLMs (Gemini) for semantic claim detection.
+
+```toml
+[llm]
+enabled = false  # OPT-IN
+provider = "gemini"
+model = "gemini-3-flash-preview"
+api_key_env = "GEMINI_API_KEY"
+```
+
+Requires API key in environment.
+
+### Learning & Autonomous Promotion
+
+**CRITICAL:** Both require explicit opt-in.
+
+```toml
+[learning]
+enabled = false  # Pattern learning from scans
+
+[autonomous]
+enabled = false  # Auto-promotion to extractors (kill switch)
+```
+
+See [vision-gaps.md](vision-gaps.md) for implementation status.
+
+---
+
+## Environment Variables
+
+Aphoria respects these environment variables:
+
+| Variable | Purpose | Default |
+|----------|---------|---------|
+| `APHORIA_API_KEY` | Hosted mode API key | None (required if hosted.enabled) |
+| `GEMINI_API_KEY` | Gemini API key | None (required if llm.enabled) |
+| `STEMEDB_DB_DIR` | Override `data_dir` | `.aphoria/db` |
+| `APHORIA_CONFIG` | Config file path | `.aphoria/config.toml` |
+
+---
+
+## Migration Guide
+
+### From Old Home-Based Database
+
+**Before (legacy):**
+```toml
+# Default in old versions: ~/.aphoria/db
+```
+
+**After (new default):**
+```toml
+# Default now: ./.aphoria/db (per-project)
+```
+
+**To keep legacy behavior:**
+```toml
+[episteme]
+data_dir = "~/.aphoria/db"
+```
+
+No migration needed - just set `data_dir` to old path.

+# Corpus Database Architecture
+
+**Audience:** Engineers integrating Aphoria with StemeDB API, ops teams deploying both systems.
+
+**What you'll learn:**
+- How Aphoria's corpus database integrates with StemeDB API
+- URI scheme inference for authoritative sources
+- Where CLI-created corpus items live
+- Git hooks for automatic binary rebuilds
+- Production deployment patterns
+
+---
+
+## Quick Reference
+
+```bash
+# Aphoria CLI writes to:
+~/.aphoria/corpus-db/
+
+# StemeDB API reads from:
+data/db/  # Default, or configure STEMEDB_CORPUS_DB_DIR
+
+# Make API see Aphoria corpus:
+export STEMEDB_CORPUS_DB_DIR="$HOME/.aphoria/corpus-db"
+stemedb-api
+```
+
+---
+
+## Database Separation
+
+### The Problem
+
+Aphoria and StemeDB API use separate databases:
+
+```
+Aphoria CLI:
+  └─ corpus create/build → ~/.aphoria/corpus-db/
+
+StemeDB API:
+  └─ GET /v1/aphoria/corpus → data/db/
+
+Result: Items created via CLI aren't visible in API/Dashboard
+```
+
+### The Solution
+
+Three integration patterns:
+
+#### Pattern 1: Shared Database (Recommended for Development)
+
+Point API to Aphoria's corpus database:
+
+```bash
+# .env
+STEMEDB_CORPUS_DB_DIR=/home/user/.aphoria/corpus-db
+
+# Start API
+cargo run --release -p stemedb-api
+```
+
+**Pros:**
+- Zero synchronization needed
+- Single source of truth
+- Changes immediately visible
+
+**Cons:**
+- API has read-only access (can't write to corpus)
+- Not suitable if API needs to write corpus items
+
+#### Pattern 2: Unified Database (Recommended for Production)
+
+Use shared directory for both:
+
+```bash
+# Create shared directory
+sudo mkdir -p /var/lib/stemedb/corpus
+sudo chown aphoria:stemedb /var/lib/stemedb/corpus
+sudo chmod 775 /var/lib/stemedb/corpus
+```
+
+```toml
+# .aphoria/config.toml
+[episteme]
+corpus_data_dir = "/var/lib/stemedb/corpus"
+```
+
+```bash
+# StemeDB API
+export STEMEDB_CORPUS_DB_DIR="/var/lib/stemedb/corpus"
+```
+
+**Pros:**
+- Single database, no sync
+- Both systems have write access
+- Production-ready pattern
+
+**Cons:**
+- Requires deployment coordination
+- Permissions management needed
+
+#### Pattern 3: Sync Mechanism (Future)
+
+```bash
+# Planned (not yet implemented)
+aphoria corpus sync --to-api --api-db-dir data/db
+```
+
+**Use case:** When databases must remain separate.
+
+---
+
+## URI Scheme Inference
+
+### The Problem
+
+Corpus items need URI-schemed subjects for API prefix scanning:
+
+```bash
+# Without URI scheme (won't work):
+subject: "tls/certificate_verification"
+
+# API queries:
+curl '/v1/aphoria/corpus?sources[]=rfc'
+# Scans for "subject:rfc://" → doesn't match plain subjects
+```
+
+### The Solution
+
+Automatic URI inference based on authority and tier:
+
+```rust
+// In aphoria corpus create
+Authority: "RFC 5246 Section 7.4.2"
+Tier: 0
+
+// Auto-inferred:
+subject_uri: "rfc://tls/certificate_verification"
+```
+
+### Inference Rules
+
+| Condition | Scheme | Example |
+|-----------|--------|---------|
+| Already has `://` | Preserved | `rfc://test` → `rfc://test` |
+| Authority contains "rfc" (case-insensitive) | `rfc://` | "RFC 5280" → `rfc://...` |
+| Authority contains "owasp" | `owasp://` | "OWASP Top 10" → `owasp://...` |
+| Authority contains "cwe" | `cwe://` | "CWE-120" → `cwe://...` |
+| Tier 2 | `vendor://` | GitHub docs → `vendor://...` |
+| Tier 3 | `community://` | Team wiki → `community://...` |
+| Tier 0/1 unrecognized | `corpus://` | Unknown → `corpus://...` |
+
+**Priority:** Authority matching > Tier-based > Fallback
+
+### Examples
+
+```bash
+# RFC claim (tier 0)
+aphoria corpus create \
+  --subject "tls/validation" \
+  --authority "RFC 5280 Section 6.1" \
+  --tier 0
+# Stored as: subject:rfc://tls/validation
+
+# OWASP claim (tier 1)
+aphoria corpus create \
+  --subject "password/storage" \
+  --authority "OWASP Password Storage Cheat Sheet" \
+  --tier 1
+# Stored as: subject:owasp://password/storage
+
+# Vendor docs (tier 2)
+aphoria corpus create \
+  --subject "postgresql/connection_pool" \
+  --authority "PostgreSQL Documentation" \
+  --tier 2
+# Stored as: subject:vendor://postgresql/connection_pool
+
+# Community (tier 3)
+aphoria corpus create \
+  --subject "api/rest/pagination" \
+  --authority "Team wiki: API standards" \
+  --tier 3
+# Stored as: subject:community://api/rest/pagination
+
+# Already schemed (preserved)
+aphoria corpus create \
+  --subject "custom://myapp/feature" \
+  --authority "Internal spec" \
+  --tier 2
+# Stored as: subject:custom://myapp/feature
+```
+
+---
+
+## CLI-Created Corpus Source
+
+### The Problem
+
+Items created with `aphoria corpus create` weren't visible in:
+
+```bash
+aphoria corpus list
+# Showed: RFC, OWASP, VendorDocs
+# Missing: CLI-created items
+
+aphoria corpus build
+# Total assertions: 86
+# Missing: CLI-created items
+```
+
+### The Solution
+
+CLI-created items are now a first-class corpus source:
+
+```rust
+// Tagged at creation time
+metadata: {
+    "source": "cli_create",
+    "description": "...",
+    "authority_source": "...",
+    "category": "..."
+}
+
+// Discovered by CliCreatedBuilder
+impl AsyncCorpusBuilder for CliCreatedBuilder {
+    async fn build(...) -> Vec<Assertion> {
+        // Scan corpus DB
+        // Filter by metadata: "source": "cli_create"
+        // Return assertions
+    }
+}
+```
+
+### Now They Appear
+
+```bash
+aphoria corpus list
+# Available corpus sources:
+#   rfc:// (Tier 0) - RFC
+#   owasp:// (Tier 1) - OWASP
+#   vendor:// (Tier 2) - VendorDocs
+#   cli:// (Tier 3) - CLI-Created Items  ← NEW
+
+aphoria corpus build
+# Corpus build complete:
+#   Total assertions: 157
+#   CLI-Created Items: 3 assertions  ← NEW
+```
+
+### Querying CLI-Created Items
+
+```bash
+# Via API
+curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=cli'
+
+# Via Dashboard
+# Navigate to: http://localhost:3000/corpus
+# Filter by "CLI-Created" source
+```
+
+---
+
+## Git Hooks for Binary Rebuilds
+
+### The Problem
+
+Developer workflow:
+1. `git pull` (gets CLI definition changes)
+2. Run `aphoria corpus create`
+3. Error: "unrecognized subcommand 'create'"
+4. Confusion, time wasted
+5. Realize binary is stale: `cargo build --release -p aphoria`
+
+### The Solution
+
+Automatic rebuild hooks:
+
+```bash
+# .git/hooks/post-merge
+if git diff-tree ... | grep -q "^applications/aphoria/src/cli"; then
+    echo "🔧 CLI changed, rebuilding aphoria..."
+    cargo build --release -p aphoria
+fi
+```
+
+### Installed Hooks
+
+**post-merge** - After `git pull` or `git merge`
+**post-checkout** - After `git checkout <branch>`
+**post-rewrite** - After `git rebase`
+
+### What Triggers Rebuild
+
+- **Aphoria CLI**: `applications/aphoria/src/cli/`
+- **API handlers**: `crates/stemedb-api/src/`
+- **Simulator**: `crates/stemedb-sim/src/`
+- **Core libraries**: `crates/stemedb-*`
+- **Dependencies**: `Cargo.toml` changes
+
+### Installation
+
+Hooks are in `.git/hooks/` (not tracked by git). To install on new clone:
+
+```bash
+cd /home/jml/Workspace/stemedb
+ls -la .git/hooks/post-*
+
+# If missing, check GIT-HOOKS-IMPLEMENTATION.md for setup
+```
+
+### Bypass Hook (Emergency)
+
+```bash
+# Temporarily disable all hooks
+git pull --no-verify
+
+# Or set env var
+GIT_HOOKS_DISABLE=1 git pull
+```
+
+---
+
+## Deployment Configurations
+
+### Local Development
+
+**Aphoria:**
+```bash
+# Default: uses ~/.aphoria/corpus-db/
+aphoria corpus create ...

+
+---
+
+## Integration Patterns
+
+### Pattern A: API-First (Read-Only Corpus)
+
+**Use case:** Dashboard-driven architecture, corpus rarely changes.
+
+```
+Workflow:
+1. Ops team creates corpus items via CLI
+2. API serves them to dashboard
+3. Developers view in dashboard (read-only)
+
+Database:
+- Aphoria: ~/.aphoria/corpus-db/ (write)
+- API: points to Aphoria DB (read)
+```
+
+**Config:**
+```bash
+# API
+export STEMEDB_CORPUS_DB_DIR="$HOME/.aphoria/corpus-db"
+```
+
+### Pattern B: CLI-First (Frequent Corpus Updates)
+
+**Use case:** Active corpus curation, frequent CLI usage.
+
+```
+Workflow:
+1. Developers create corpus items via CLI
+2. CLI builds corpus
+3. API/dashboard reflect latest corpus
+
+Database:
+- Aphoria: /var/lib/stemedb/corpus (write)
+- API: /var/lib/stemedb/corpus (read)
+```
+
+**Config:**
+```toml
+# .aphoria/config.toml
+[episteme]
+corpus_data_dir = "/var/lib/stemedb/corpus"
+```
+
+```bash
+# API
+export STEMEDB_CORPUS_DB_DIR="/var/lib/stemedb/corpus"
+```
+
+### Pattern C: Hybrid (Separate Stores + Sync)
+
+**Use case:** Different corpus items in different stores.
+
+```
+Workflow:
+1. Aphoria: authoritative corpus (RFC, OWASP, CLI-created)
+2. API: ephemeral assertions from scans
+3. Periodic sync or query union
+
+Database:
+- Aphoria: ~/.aphoria/corpus-db/
+- API: data/db/
+- Sync: manual or scheduled
+```
+
+**Sync (when implemented):**
+```bash
+# Planned
+aphoria corpus sync --to-api --api-db-dir data/db
+```
+
+---
+
+## Troubleshooting
+
+### "Items created but not visible in API"
+
+**Symptom:**
+```bash
+aphoria corpus create --subject "test" ...
+# Created corpus item: corpus://test/enabled
+
+curl 'http://localhost:18180/v1/aphoria/corpus'
+# {"items":[], "total_matching": 0}
+```
+
+**Diagnosis:**
+```bash
+# Check API config
+env | grep STEMEDB_CORPUS_DB_DIR
+# If empty, API is using data/db/
+
+# Check Aphoria corpus DB
+ls -la ~/.aphoria/corpus-db/
+# Should see fjall/, redb/, wal/
+```
+
+**Fix:**
+```bash
+export STEMEDB_CORPUS_DB_DIR="$HOME/.aphoria/corpus-db"
+# Restart API
+pkill -f stemedb-api
+stemedb-api &
+```
+
+### "Command not found after git pull"
+
+**Symptom:**
+```bash
+git pull
+aphoria corpus create ...
+# error: unrecognized subcommand 'create'
+```
+
+**Diagnosis:**
+```bash
+# Check binary date
+ls -lh target/release/aphoria
+# -rwxr-xr-x ... Jan 15 10:00 aphoria
+
+# Check CLI code date
+ls -lh applications/aphoria/src/cli/mod.rs
+# -rw-r--r-- ... Feb 09 14:30 mod.rs  ← Newer!
+```
+
+**Fix:**
+```bash
+# Rebuild
+cargo build --release -p aphoria
+
+# Or check if hooks are installed
+ls -la .git/hooks/post-merge
+# Should be executable and contain rebuild logic
+```
+
+### "Corpus items have wrong URI scheme"
+
+**Symptom:**
+```bash
+aphoria corpus create \
+  --subject "tls/validation" \
+  --authority "RFC 5280" \
+  --tier 0
+
+# API query fails
+curl '/v1/aphoria/corpus?sources[]=rfc'
+# {"items":[]}
+```
+
+**Diagnosis:**
+```bash
+# Check stored subject (via debug scan)
+aphoria scan --show-observations | grep tls
+# If shows: subject:tls/validation (no rfc://)
+# Then URI inference didn't work
+```
+
+**Fix:**
+Rebuild aphoria binary (URI inference added in recent version):
+```bash
+cargo build --release -p aphoria
+```
+
+### "Dashboard shows duplicate corpus items"
+
+**Symptom:**
+Dashboard displays same item multiple times.
+
+**Diagnosis:**
+```bash
+# Check if corpus built multiple times
+aphoria corpus build --verbose
+# Look for same assertion appearing under multiple builders
+```
+
+**Cause:**
+CLI-created items might also match RFC/OWASP builders if they have matching metadata.
+
+**Fix:**
+This is expected behavior if:
+1. Item was created via CLI with RFC authority
+2. RFC builder also fetches it from RFC source
+3. Both versions appear in corpus
+
+To deduplicate, ensure CLI-created items use unique subjects or authorities that don't overlap with fetched sources.

+# LLM-Based Wiki Corpus Extraction
+
+Extract factual claims from technical documentation using an LLM skill that intelligently chunks, analyzes, and persists to the corpus database.
+
+## Quick Start
+
+```bash
+# Extract claims from a wiki article
+cd ~/Workspace/stemedb
+claude -p ~/path/to/wiki/article.md --skill extract-wiki-corpus
+
+# Example with actual file
+claude -p ~/Workspace/orchard9/wiki/intakes/REQUEST_FOR_RESEARCH_ANSWERS.md \
+  --skill extract-wiki-corpus
+```
+
+Expected output:
+```
+Reading article: REQUEST_FOR_RESEARCH_ANSWERS.md (12,450 tokens)
+Chunked into 3 segments (by ## headings)
+
+Chunk 1/3: "Critical Compatibility Solutions"
+  Extracted 8 claims
+  ✓ ml/basicsr/torchvision/incompatible_with = ">=0.15"
+  ✓ ml/gpen/gfpgan/outperforms = "eye_enhancement"
+  ...
+
+Chunk 2/3: "CUDA 12.9 Compatibility"
+  Extracted 5 claims
+  ...
+
+Summary: 23 claims extracted, 23 stored successfully
+```
+
+## How It Works
+
+### 1. Intelligent Chunking
+
+The skill chunks large articles to fit LLM context limits:
+
+**Strategy:**
+- Target: ~4K tokens per chunk
+- Break at `##` headings when possible
+- Preserve context: Include document title + section path in each chunk
+
+**Example:**
+```markdown
+# Python Dependency Stack
+## Critical Solutions
+### BasicSR Fix
+[content...]
+```
+
+Becomes 3 chunks:
+1. `"Python Dependency Stack / Critical Solutions / BasicSR Fix"` + content
+2. `"Python Dependency Stack / Critical Solutions / GPEN vs GFPGAN"` + content
+3. `"Python Dependency Stack / CUDA Compatibility"` + content
+
+### 2. LLM Claim Extraction
+
+For each chunk, Claude extracts factual assertions as structured JSON:
+
+**Extraction Criteria:**
+- Factual (verifiable from text)
+- Useful for developers
+- Has clear subject/predicate/value
+
+**Example extraction:**
+
+Input text:
+```markdown
+### BasicSR/Torchvision Fix
+The core issue is that basicsr 1.4.2 imports from
+`torchvision.transforms.functional_tensor` which was removed in
+torchvision 0.15+.
+
+**Primary Solution:**
+git+https://github.com/XPixelGroup/BasicSR@8d56e3a
+```
+
+Extracted claim:
+```json
+{
+  "subject": "ml/dependencies/basicsr/torchvision",
+  "predicate": "incompatible_with",
+  "value": ">=0.15",
+  "explanation": "basicsr 1.4.2 imports from torchvision.transforms.functional_tensor which was removed in torchvision 0.15+",
+  "authority": "XPixelGroup/BasicSR@8d56e3a",
+  "category": "compatibility"
+}
+```
+
+### 3. Authority Inference
+
+The LLM infers authority sources from context:
+
+| Pattern | Authority Format | Example |
+|---------|-----------------|---------|
+| GitHub URL | `repo@commit` | `XPixelGroup/BasicSR@8d56e3a` |
+| Research paper | `Author et al. (Year)` | `Smith et al. (2023)` |
+| Official docs | `Product Documentation` | `PyTorch Documentation` |
+| Empirical | `Community consensus` | `Community best practice` |
+
+### 4. Tier Assignment
+
+The skill assigns tiers based on authority source:
+
+| Tier | Authority Type | Examples |
+|------|---------------|----------|
+| 0 | Regulatory specs | RFC, W3C standards |
+| 1 | Authoritative sources | Official docs, research papers |
+| 2 | Observational | GitHub repos, community consensus |
+| 3 | Empirical | Unverified claims |
+
+**Guidance to LLM:**
+- Official standards (RFC, W3C) → Tier 0
+- Official documentation, published research → Tier 1
+- GitHub repos, maintainer statements → Tier 2
+- Community reports, unverified → Tier 3
+
+### 5. Persistence via CLI
+
+Each extracted claim is stored using:
+
+```bash
+aphoria corpus create \
+  --subject "ml/dependencies/basicsr/torchvision" \
+  --predicate "incompatible_with" \
+  --value ">=0.15" \
+  --explanation "basicsr 1.4.2 imports from torchvision.transforms.functional_tensor which was removed in 0.15+" \
+  --authority "XPixelGroup/BasicSR@8d56e3a" \
+  --category "compatibility" \
+  --tier 2
+```
+
+## CLI Reference: `aphoria corpus create`
+
+Create a corpus assertion from structured claim data.
+
+**Usage:**
+```bash
+aphoria corpus create \
+  --subject <hierarchical/path> \
+  --predicate <relationship> \
+  --value <value> \
+  --explanation <full-context> \
+  --authority <source> \
+  --category <category> \
+  --tier <0-3>
+```
+
+**Arguments:**
+
+| Flag | Required | Description | Example |
+|------|----------|-------------|---------|
+| `--subject` | Yes | Hierarchical path to concept | `ml/basicsr/torchvision` |
+| `--predicate` | Yes | Relationship type | `incompatible_with` |
+| `--value` | Yes | Value or constraint | `">=0.15"` |
+| `--explanation` | Yes | Full context sentence | `"basicsr 1.4.2 imports from..."` |
+| `--authority` | Yes | Source citation | `XPixelGroup/BasicSR@8d56e3a` |
+| `--category` | Yes | Category tag | `compatibility` |
+| `--tier` | Yes | Authority tier (0-3) | `2` |
+
+**Categories:**
+- `compatibility` - Dependency constraints, version requirements
+- `performance` - Performance characteristics, benchmarks
+- `security` - Security properties, vulnerabilities
+- `architecture` - Design patterns, structure
+- `behavior` - Functional behavior, side effects
+
+**Behavior:**
+
+**Deduplication:** Stores ALL claims, even if subject+predicate exists. This is append-only; sourced differing claims are the whole point of Episteme.
+
+**Error Handling:** Bundles all validation errors and presents them together:
+
+```
+Error creating corpus assertion:
+
+Validation errors:
+  1. --subject: Must be non-empty hierarchical path (got: "")
+  2. --tier: Must be 0-3 (got: 5)
+  3. --category: Must be one of: compatibility, performance, security, architecture, behavior (got: "random")
+
+Fix all errors and retry.
+```
+
+**Example:**
+```bash
+$ aphoria corpus create \
+  --subject "ml/pytorch/version" \
+  --predicate "requires" \
+  --value ">=2.0" \
+  --explanation "Uses torch.compile which requires PyTorch 2.0+" \
+  --authority "PyTorch 2.0 Release Notes" \
+  --category "compatibility" \
+  --tier 1
+
+✓ Created corpus assertion: ml/pytorch/version
+  Stored in: ~/.aphoria/corpus-db
+```
+
+## Skill Output Format
+
+The `extract-wiki-corpus` skill produces structured output:
+
+```
+Reading article: REQUEST_FOR_RESEARCH_ANSWERS.md (12,450 tokens)
+Chunked into 3 segments (by ## headings)
+
+Chunk 1/3: "Critical Compatibility Solutions"
+  Extracted 8 claims
+
+  1. ml/dependencies/basicsr/torchvision
+     incompatible_with = ">=0.15"
+     Authority: XPixelGroup/BasicSR@8d56e3a
+     ✓ Stored
+
+  2. ml/enhancements/gpen/gfpgan

+  Extracted 5 claims
+
+  9. ml/face_detection/mediaipe/dlib
+     preferred_over = "CUDA 12 support"
+     Authority: Community consensus
+     ✓ Stored
+
+  [... 4 more claims ...]
+
+Chunk 3/3: "Optimized Requirements"
+  Extracted 10 claims
+
+  [... all claims ...]
+
+Summary:
+  Total claims: 23
+  Successfully stored: 23
+  Failed: 0
+
+Corpus database: ~/.aphoria/corpus-db
+Query: curl 'http://localhost:18180/v1/aphoria/corpus?category=compatibility'
+```
+
+**If errors occur:**
+```
+Summary:
+  Total claims: 23
+  Successfully stored: 18
+  Failed: 5
+
+Errors:
+  1. Claim #7 (ml/torch/cuda/version)
+     - --tier: Must be 0-3 (got: 5)
+     - Fix: LLM assigned invalid tier
+
+  2. Claim #12 (ml/xformers/optional)
+     - --subject: Empty subject path
+     - Fix: LLM extraction failed
+
+  [... 3 more errors with details ...]
+
+Fix these issues and re-run extraction.
+```
+
+## Verification
+
+After extraction, verify claims appear in the corpus:
+
+```bash
+# Query all compatibility claims
+curl -s 'http://localhost:18180/v1/aphoria/corpus?category=compatibility' | jq '.total_matching'
+# Expected: 23 (or however many were extracted)
+
+# Query specific subject
+curl -s 'http://localhost:18180/v1/aphoria/corpus' | \
+  jq '.items[] | select(.subject | contains("basicsr"))'
+
+# Expected output:
+{
+  "subject": "ml/dependencies/basicsr/torchvision",
+  "predicate": "incompatible_with",
+  "value": ">=0.15",
+  "source": "ml://",
+  "tier": 2,
+  "category": "compatibility",
+  "explanation": "basicsr 1.4.2 imports from torchvision.transforms.functional_tensor which was removed in 0.15+",
+  "authority_source": "XPixelGroup/BasicSR@8d56e3a"
+}
+```
+
+## Dashboard View
+
+Extracted claims appear in the Aphoria dashboard at `/corpus`:
+
+**Filters:**
+- By category: compatibility, performance, security, architecture, behavior
+- By tier: 0 (Regulatory), 1 (Authoritative), 2 (Observational), 3 (Empirical)
+- By source: ml://, security://, etc.
+
+**Display:**
+- Subject path as breadcrumbs: `ml > dependencies > basicsr > torchvision`
+- Tier badge with color coding
+- Full explanation text
+- Authority citation as link (if URL)
+
+## Troubleshooting
+
+**Problem:** Skill chunks too aggressively, loses context
+
+**Solution:** Adjust chunk size in skill configuration (target 4K tokens, can go up to 8K for complex articles)
+
+---
+
+**Problem:** LLM assigns wrong tiers
+
+**Solution:** Refine tier guidance in skill prompt:
+- Official standards (RFC, IEEE) → Tier 0
+- Official docs, peer-reviewed papers → Tier 1
+- GitHub repos, maintainer statements → Tier 2
+- Blog posts, community forums → Tier 3
+
+---
+
+**Problem:** Too many failed claims (validation errors)
+
+**Solution:** Check common error patterns:
+```bash
+# Review failed claims
+grep "Failed:" /tmp/extraction-output.log
+
+# Common issues:
+# 1. Empty subjects - LLM extraction failed
+# 2. Invalid tiers - LLM assigned tier > 3
+# 3. Missing required fields - Incomplete extraction
+```
+
+Fix by refining LLM extraction prompt.
+
+---
+
+**Problem:** Duplicate claims (same subject+predicate)
+
+**This is expected behavior.** Episteme stores ALL claims, even duplicates from different sources. This enables:
+- Sourced differing opinions (PyTorch docs say X, community says Y)
+- Conflict detection (authority says A, codebase does B)
+- Historical tracking (claim evolved over time)
+
+To query all claims for a subject:
+```bash
+curl -s 'http://localhost:18180/v1/aphoria/corpus' | \
+  jq '.items[] | select(.subject == "ml/dependencies/basicsr/torchvision")'
+```
+
+## Integration with Other Features
+
+**With Scans:**
+- Corpus claims act as authority sources
+- Aphoria compares scanned observations against corpus
+- Conflicts trigger violations
+
+**With Claims Management:**
+- Can supersede corpus claims: `aphoria claims supersede <id>`
+- Can deprecate outdated corpus: `aphoria claims deprecate <id>`
+- Corpus claims have same structure as project claims
+
+**With Dashboard:**
+- All corpus claims visible at `/corpus`
+- Filterable by category, tier, source
+- Click through to see full explanation
+
+## Best Practices
+
+**DO:**
+- Extract from authoritative sources (official docs, research)
+- Verify claims appear in dashboard after extraction
+- Review tier assignments for accuracy
+- Include full context in explanations
+
+**DON'T:**
+- Extract from opinion pieces or blogs (or use tier 3)
+- Skip authority citations (always provide source)
+- Use vague subjects ("thing" → "ml/pytorch/feature/specific")
+- Ignore validation errors (fix all before considering extraction complete)

+# Scale-Adaptive Promotion Thresholds
+
+## Overview
+
+Scale-adaptive thresholds automatically adjust promotion criteria based on organization size, enabling small teams to see value immediately while maintaining quality gates for larger organizations.
+
+## The Problem
+
+**Before adaptive thresholds:**
+- Hardcoded minimums: 850/100/50 projects for regulatory/clinical/emerging
+- Small teams (2-5 projects) → **0 patterns promoted** → empty dashboard
+- No immediate value demonstration → adoption killed before flywheel starts
+
+**Root cause:**
+- Thresholds designed for enterprise scale (850 projects for regulatory)
+- Small teams locked out: can't meet 50-project minimum for emerging tier
+- Dashboard queries promoted patterns only (no visibility into raw aggregates)
+
+## The Solution
+
+### Adaptive Formula
+
+```rust
+effective_min_projects = max(
+    absolute_floor,           // Safety: prevent single-project noise
+    (percentage * total_projects).ceil()  // Scale: grow with team
+)
+```
+
+### Scale Tiers (Auto-Detected)
+
+| Tier | Project Range | Behavior |
+|------|--------------|----------|
+| **Micro** | 1-5 | Only emerging tier, floor=2, rate=50% |
+| **Small** | 6-25 | All tiers enabled, lower floors |
+| **Medium** | 26-100 | Balanced thresholds |
+| **Large** | 101-500 | Higher quality gates |
+| **Enterprise** | 501+ | Current defaults (backward compatible) |
+
+### Example: Emerging Tier Scaling
+
+| Team Size | Projects | Formula | Min Projects | Adoption Required |
+|-----------|----------|---------|--------------|-------------------|
+| Micro | 3 | `max(2, 0.50*3)` | **2** | 2/3 projects (67%) |
+| Small | 10 | `max(2, 0.40*10)` | **4** | 4/10 projects (40%) |
+| Medium | 50 | `max(5, 0.40*50)` | **20** | 20/50 projects (40%) |
+| Enterprise | 1000 | `max(25, 0.50*1000)` | **500** | 500/1000 projects (50%) |
+
+## Quality Maintained
+
+✅ **Floor prevents noise:** Single-project patterns blocked
+✅ **Adoption rate required:** Community consensus still matters
+✅ **Authority matching enforced:** Regulatory/clinical tiers need RFC/OWASP match
+✅ **Manual review:** Emerging tier still requires review (auto_promote=false)
+✅ **Backward compatible:** Enterprise behavior unchanged
+
+## Configuration
+
+### Default (Adaptive)
+
+```toml
+# .aphoria/config.toml
+[corpus]
+use_community = true
+aggregation_enabled = true
+# adaptive_thresholds = <optional custom thresholds>
+use_legacy_thresholds = false  # Default: use adaptive
+```
+
+### Legacy Mode (Static Thresholds)
+
+```toml
+[corpus]
+use_legacy_thresholds = true  # Use fixed 850/100/50
+```
+
+### Custom Thresholds
+
+```toml
+[corpus.adaptive_thresholds.micro.emerging]
+min_projects_floor = 1       # Override: allow 1 project (risky!)
+min_projects_percentage = 0.40
+min_adoption_rate = 0.40
+```
+
+## Implementation
+
+### Core Components
+
+1. **`ScaleTier`** (`corpus/thresholds.rs`):
+   - `from_total_projects(u64) -> ScaleTier`
+   - Auto-detects tier from project count
+
+2. **`AdaptiveCriteria`** (`corpus/thresholds.rs`):
+   - `effective_min_projects(total_projects) -> u64`
+   - Applies `max(floor, percentage * total)` formula
+
+3. **`ScaleAdaptiveThresholds`** (`corpus/thresholds.rs`):
+   - `evaluate(project_count, total_projects, ...) -> PromotionDecision`
+   - Returns `AutoPromote(tier)`, `RequireReview`, or `Skip`
+
+4. **`CommunityCorpusBuilder`** (`corpus/community.rs`):
+   - Updated to use adaptive thresholds when `use_adaptive=true`
+   - Falls back to legacy thresholds when `use_legacy_thresholds=true`
+   - Logs scale tier and threshold mode on build
+
+### Configuration Fields
+
+**`CorpusConfig`** (`config/types/scan.rs`):
+- `adaptive_thresholds: Option<ScaleAdaptiveThresholds>` - Custom thresholds
+- `use_legacy_thresholds: bool` - Backward compatibility flag (default: false)
+
+## Usage
+
+### Micro Team Example (3 projects)
+
+```bash
+# Scan 3 projects
+cd project1 && aphoria scan --persist --sync
+cd project2 && aphoria scan --persist --sync
+cd project3 && aphoria scan --persist --sync
+
+# Check logs
+# Should see:
+# scale_tier=Micro, use_adaptive=true
+# Pattern promoted: 2/3 projects (67%) → RequireReview
+```
+
+### Query Patterns
+
+```bash
+# API: Patterns with min 1 project (shows all for micro teams)
+curl 'http://localhost:18180/api/patterns?min_projects=1&limit=10'
+
+# Dashboard will show:
+# - Scale tier: "Micro (3 projects)"
+# - Promoted patterns visible
+# - Thresholds: "Emerging: 2/3 projects (67%)"
+```
+
+## Testing
+
+### Unit Tests
+
+- `test_scale_tier_detection()` - Verify tier boundaries
+- `test_effective_min_projects()` - Floor vs percentage dominance
+- `test_micro_team_promotion()` - 2/3 projects promoted
+- `test_regulatory_disabled_for_micro()` - Tier disabling works
+- `test_enterprise_backward_compatible()` - Same as legacy
+
+### Integration Tests
+
+- `scale_adaptive_test.rs` - 7 tests covering all scenarios
+- All 1199 library tests pass
+
+## Migration
+
+**Existing deployments:** No action required
+- Adaptive thresholds default to enabled
+- Enterprise behavior unchanged (501+ projects)
+- Legacy mode available if needed
+
+**New deployments:** Immediate value
+- Small teams see patterns after 2-3 scans
+- Quality maintained via floors and adoption rates
+- Natural growth path as team scales
+
+## Philosophy
+
+**Start simple, scale naturally:**
+- Small teams see value immediately (2-3 projects → patterns visible)
+- Quality maintained via floors (no single-project noise)
+- Adoption rate still matters (community consensus)
+- Enterprise behavior unchanged (backward compatible)
+- Configuration optional (defaults work for 95%)
+
+**This unlocks the flywheel:**
+- Small teams adopt → see patterns → gain trust
+- Teams grow → thresholds tighten → quality improves
+- Cross-team patterns emerge → community corpus strengthens
+- No manual threshold tuning required

+/// Query string extractor that supports bracket notation (e.g., `?sources[]=value1&sources[]=value2`).
+///
+/// This extractor uses `serde_qs` instead of `serde_urlencoded` to properly handle
+/// array parameters with bracket notation, which is the standard format used by
+/// JavaScript's URLSearchParams and the StemeDB Dashboard.
+///
+/// # When to Use QsQuery vs Query
+///
+/// **Use `QsQuery` when:**
+/// - Your request DTO contains `Vec<T>` or `Option<Vec<T>>` fields
+/// - The endpoint is called by the dashboard or JavaScript clients
+/// - You need bracket notation support: `?filters[]=a&filters[]=b`
+///
+/// **Use standard `axum::extract::Query` when:**
+/// - All query parameters are scalars (String, usize, bool, Option<String>, etc.)
+/// - No array/vector parameters needed
+/// - Simpler and lighter weight for non-array cases
+///
+/// # Example
+///
+/// ```rust,ignore
+/// use stemedb_api::extractors::QsQuery;
+/// use serde::Deserialize;
+///
+/// #[derive(Deserialize)]
+/// struct MyRequest {
+///     sources: Option<Vec<String>>,  // Array parameter
+///     limit: usize,                  // Scalar parameter
+/// }
+///
+/// // ✅ Correct - QsQuery handles both array and scalar params
+/// async fn handler(QsQuery(params): QsQuery<MyRequest>) {
+///     // Dashboard sends: ?sources[]=rfc&sources[]=community&limit=10
+///     // params.sources = Some(vec!["rfc", "community"])
+///     // params.limit = 10
+/// }
+///
+/// // ❌ Wrong - standard Query can't parse bracket notation
+/// async fn wrong_handler(Query(params): Query<MyRequest>) {
+///     // Dashboard sends: ?sources[]=rfc&sources[]=community
+///     // Result: params.sources = None (silently fails!)
+/// }
+/// ```
+///
+/// # Dashboard Compatibility
+///
+/// The StemeDB Dashboard uses JavaScript's `URLSearchParams.append()` which generates
+/// bracket notation for arrays:
+///
+/// ```javascript
+/// // Dashboard code
+/// params.sources.forEach(s => searchParams.append("sources[]", s));
+/// // Generates: ?sources[]=rfc&sources[]=owasp&sources[]=community
+/// ```
+///
+/// If you use standard `Query` for array parameters, the dashboard filters will appear
+/// to work but silently fail (returning all results instead of filtered results).
