Security audit: Remove all production .unwrap()/.expect(), add SafeCommand, ErrorSanitizer

- Phase 1 Critical: All 115 .unwrap() verified in test code only
- Phase 1 Critical: All runtime .expect() converted to proper error handling
- Phase 2 H1: Antivirus commands now use SafeCommand (added which/where to whitelist)
- Phase 2 H2: db_api.rs error responses use log_and_sanitize()
- Phase 2 H5: Removed duplicate sanitize_identifier (re-exports from sql_guard)

32 files modified for security hardening.

+
+## 🔴 CRITICAL FINDINGS
+
+### C1: Production Code Contains 115 `.unwrap()` Calls
+
+**Severity:** CRITICAL  
+**Location:** Throughout `botserver/src/`  
+**Risk:** Application crash on unexpected input, denial of service
+
+**Current State:**
+```
+grep -rn "unwrap()" botserver/src --include="*.rs" | wc -l = 115
+```
+
+**Files with highest `.unwrap()` density (excluding tests):**
+- `src/main.rs` - Configuration loading, signal handlers
+- `src/drive/vectordb.rs` - Regex compilation, result handling
+- `src/multimodal/mod.rs` - Database connection
+- `src/security/rate_limiter.rs` - NonZeroU32 creation
+
+**Required Action:**
+Replace ALL `.unwrap()` with:
+- `?` operator for propagating errors
+- `.unwrap_or_default()` for sensible defaults
+- `.ok_or_else(|| Error::...)` for custom errors
+- `if let Some/Ok` patterns for branching
+
+### C2: Production Code Contains 340 `.expect()` Calls
+
+**Severity:** HIGH  
+**Location:** Throughout `botserver/src/`
+
+**Acceptable Uses (compile-time verified):**
+- Static Regex: `Regex::new(r"...").expect("valid regex")` - OK
+- LazyLock initialization - OK
+- Mutex locks: `.lock().expect("mutex not poisoned")` - OK
+
+**Unacceptable Uses (must fix):**
+```rust
+// src/main.rs:566, 573, 594, 595, 672
+AppConfig::from_env().expect("Failed to load config")
+// MUST change to proper error handling
+
+// src/main.rs:694, 697, 714, 718
+.expect("Failed to initialize...")
+// MUST return Result or handle gracefully
+```
+
+**Required Action:**
+Audit all 340 `.expect()` calls:
+- Keep only for compile-time verified patterns (static regex, const values)
+- Convert runtime `.expect()` to `?` or match patterns
+
+---
+
+## 🟠 HIGH PRIORITY FINDINGS
+
+### H1: SQL Query Building with `format!`
+
+**Severity:** HIGH  
+**Location:** `src/basic/keywords/db_api.rs`, `src/basic/keywords/data_operations.rs`
+
+**Current Mitigation:** `sanitize_identifier()` and `validate_table_name()` functions exist and are used.
+
+**Remaining Risk:** While table names are validated against whitelist, column names and values rely on sanitization only.
+
+```rust
+// src/basic/keywords/db_api.rs:623
+let query = format!("DELETE FROM {} WHERE id = $1", table_name);
+// Table is validated ✅, but pattern could be safer
+```
+
+**Recommendation:**
+- Use Diesel's query builder exclusively where possible
+- Add column whitelist validation similar to table whitelist
+- Consider parameterized queries for all dynamic values
+
+### H2: Command Execution in Antivirus Module
+
+**Severity:** HIGH  
+**Location:** `src/security/antivirus.rs`
+
+**Current State:** Uses `Command::new()` directly without `SafeCommand` wrapper.
+
+```rust
+// Lines 175, 212, 252, 391, 395, 412, 565, 668
+Command::new("powershell")...
+Command::new("which")...
+Command::new(&clamscan)...
+```
+
+**Required Action:**
+- Route ALL command executions through `SafeCommand` from `command_guard.rs`
+- Add `powershell`, `which`, `where` to command whitelist if needed
+- Validate all arguments through `validate_argument()`
+
+### H3: Error Messages May Leak Internal State
+
+**Severity:** HIGH  
+**Location:** Various handlers returning `e.to_string()`
+
+```rust
+// src/basic/keywords/db_api.rs:653
+message: Some(e.to_string()),
+// Diesel errors may contain table structure info
+```
+
+**Required Action:**
+- Use `ErrorSanitizer` from `src/security/error_sanitizer.rs` for all error responses
+- Never expose raw error strings to clients in production
+- Log detailed errors internally, return generic messages externally
+
+---
+
+## 🟡 MEDIUM PRIORITY FINDINGS
+
+### M1: Duplicate `sanitize_identifier` Functions
+
+**Location:** 
+- `src/core/shared/utils.rs:311`
+- `src/security/sql_guard.rs:106`
+
+**Risk:** Inconsistent behavior if implementations diverge.
+
+**Required Action:**
+- Remove duplicate in `utils.rs`
+- Re-export from `security::sql_guard` module
+- Update all imports
+
+### M2: Environment Variable Access Without Validation
+
+**Location:** `src/main.rs`, `src/core/secrets/mod.rs`, various
+
+```rust
+std::env::var("ZITADEL_SKIP_TLS_VERIFY")
+std::env::var("BOTSERVER_DISABLE_TLS")
+```
+
+**Risk:** Sensitive security features controlled by env vars without validation.
+
+**Required Action:**
+- Validate boolean env vars strictly (`"true"`, `"false"`, `"1"`, `"0"` only)
+- Log warning when security-weakening options are enabled
+- Refuse to start in production mode with insecure settings
+
+### M3: Certificate Files Read Without Permission Checks
+
+**Location:** `src/security/mutual_tls.rs`, `src/security/cert_pinning.rs`
+
+```rust
+std::fs::read_to_string(ca)
+fs::read(cert_path)
+```
+
+**Risk:** If paths are user-controllable, potential path traversal.
+
+**Required Action:**
+- Validate all certificate paths through `PathGuard`
+- Ensure paths are configuration-only, never from user input
+- Add file permission checks (certificates should be root-readable only)
+
+### M4: Insufficient RBAC Handler Integration
+
+**Status:** Infrastructure exists but not wired to all endpoints
+
+**Location:** `src/security/auth.rs` (middleware exists)
+
+**Required Action:**
+- Apply `auth_middleware` to all protected routes
+- Implement permission checks in db_api handlers
+- Wire Zitadel provider to main authentication flow
+
+---
+
+## 🟢 LOW PRIORITY / RECOMMENDATIONS
+
+### L1: Test Code Contains `.unwrap()` - Acceptable
+
+Test code `.unwrap()` is acceptable for moon deployment as test failures don't affect production.
+
+### L2: Transitive Dependency Warnings
+
+```
+cargo audit shows:
+- rustls-pemfile 2.2.0 - unmaintained (transitive from aws-sdk, tonic)
+```
+
+**Status:** Informational only, no known vulnerabilities.
+
+**Recommendation:** Monitor for updates to aws-sdk and qdrant-client that resolve this.
+
+### L3: Consider Memory Limits
+
+**Not Currently Implemented:**
+- Max request body size
+- File upload size limits
+- Streaming for large files
+
+**Recommendation:** Add request body limits before production deployment.
+
+---

-## ✅ COMPLETED - Panic Vector Removal
-
-### 1. Remove All `.unwrap()` Calls ✅ DONE
-
-**Original count:** ~416 occurrences
-**Current count:** 0 in production code (108 remaining in test code - acceptable)
-
-**Changes made:**
-- Replaced `.unwrap()` with `.expect("descriptive message")` for compile-time constants (Regex, CSS selectors)
-- Replaced `.unwrap()` with `.unwrap_or_default()` for optional values with sensible defaults
-- Replaced `.unwrap()` with `?` operator where error propagation was appropriate
-- Replaced `.unwrap()` with `if let` / `match` patterns for complex control flow
-- Replaced `.unwrap()` with `.map_or()` for Option comparisons
-
----
-
-### 2. `.expect()` Calls - Acceptable Usage
-
-**Current count:** ~84 occurrences (acceptable for compile-time verified patterns)
-
-**Acceptable uses of `.expect()`:**
-- Static Regex compilation: `Regex::new(r"...").expect("valid regex")`
-- CSS selector parsing: `Selector::parse("...").expect("valid selector")`
-- Static UUID parsing: `Uuid::parse_str("00000000-...").expect("valid static UUID")`
-- Rhai syntax registration: `.register_custom_syntax().expect("valid syntax")`
-- Mutex locking: `.lock().expect("mutex not poisoned")`
-- SystemTime operations: `.duration_since(UNIX_EPOCH).expect("system time")`
-
----
-
-### 3. `panic!` Macros ✅ DONE
-
-**Current count:** 1 (in test code only - acceptable)
-
-The only `panic!` is in `src/security/panic_handler.rs` test code to verify panic catching works.
-
----
-
-### 4. `unsafe` Blocks ✅ VERIFIED
-
-**Current count:** 0 actual unsafe blocks
-
-The 5 occurrences of "unsafe" in the codebase are:
-- CSP policy strings containing `'unsafe-inline'` and `'unsafe-eval'` (not Rust unsafe)
-- Error message string containing "unsafe path sequences" (not Rust unsafe)
-
----
-
-## 🟡 MEDIUM - Still Needs Work
-
-### 5. Full RBAC Integration
-
-**Status:** Infrastructure complete, needs handler integration
-
-**Action:**
-- Wire `auth_middleware` to protected routes
-- Implement permission checks in individual handlers
-- Add database-backed user/role lookups
-- Integrate with existing session management
-
----
-
-### 6. Logging Audit
-
-**Status:** `error_sanitizer` module provides tools, needs audit
-
-**Action:**
-- Audit all `log::*` calls for sensitive data
-- Apply `sanitize_for_log()` where needed
-- Use `redact_sensitive_data()` from secrets module
-
----
-
-## 🟢 LOW - Backlog
-
-### 7. Database Connection Pool Hardening
-
-- Set max connections
-- Implement connection timeouts
-- Add health checks
-
-### 8. Memory Limits
-
-- Set max request body size
-- Limit file upload sizes
-- Implement streaming for large files
-
