✅ Configuration Implementation

File: crates/terraphim_validation/config/validation-config.toml

| Config Section | Design Spec | Implementation | Status | |----------------|-------------|----------------|---------| | [download] directory | download_dir | download_dir = "target/validation-downloads" | ✅ MATCH | | [concurrent] validations | concurrent_validations | concurrent_validations = 4 | ✅ MATCH | | [timeout] seconds | timeout_seconds | timeout_seconds = 1800 (30 min) | ✅ MATCH | | [enabled_platforms] | Platform::LinuxX86_64, etc. | All 3 platforms configured | ✅ MATCH | | [enabled_categories] | download, installation, functionality, security, performance | All 5 categories enabled | ✅ MATCH | | [performance] SLOs | max_startup_time_ms, max_api_response_time_ms | SLOs defined | ✅ MATCH | | [security] scanning | vulnerability_scan, max_severity | OSV database configured | ✅ MATCH |

✅ ValidationOrchestrator Implementation

File: crates/terraphim_validation/src/orchestrator/mod.rs

Methods Verified:

✅ new() → Loads config from validation-config.toml
✅ validate_release(version) → Full release validation flow
✅ validate_categories(version, categories) → Category-specific validation
✅ validate_downloads() → Checksum verification
✅ validate_installations() → Placeholder for Phase 2
✅ validate_functionality() → Placeholder for Phase 3
✅ validate_security() → Placeholder for Phase 3
✅ validate_performance() → Placeholder for Phase 3

Design Decision Tracing:

// Design Decision: Keep release vs runtime validation separate
// Implementation: Release validation config stays in crate,
// Runtime validation config stays separate (as documented)
pub struct ValidationOrchestrator {
    config: ValidationConfig,  // Release validation only
    // ...
}

2.2 Runtime Validation Track

✅ Pre/Post LLM Hook Wiring

File: crates/terraphim_multi_agent/src/agent.rs:624-676

Hook Invocation Verified:

// Pre-LLM hook
let pre_llm_context = PreLlmContext {
    prompt: format!("{} command", command_type),
    agent_id: self.agent_id.to_string(),
    conversation_history,
    token_count,
};
let pre_decision = self.hook_manager.run_pre_llm(&pre_llm_context).await?;
// ... decision handling ...

// Post-LLM hook
let post_llm_context = PostLlmContext {
    prompt: format!("{} command", command_type),
    response: response.content.clone(),
    agent_id: self.agent_id.to_string(),
    token_count,
    model: "default".to_string(),
};
let post_decision = self.hook_manager.run_post_llm(&post_llm_context).await?;
// ... decision handling ...

Decision Handling:

✅ Allow → Continue with generation/response
✅ Block { reason } → Return MultiAgentError::HookValidation
✅ Modify { transformed_code } → Transform and return (post-LLM only)
✅ AskUser { prompt } → Return MultiAgentError::HookValidation

Design Decision Tracing:

// Design Decision: Wire pre/post LLM hooks in multi_agent
// Implementation: HookManager.run_pre_llm() and run_post_llm()
// wrapped around llm_client.generate() calls

✅ Hook System Architecture

File: crates/terraphim_multi_agent/src/vm_execution/hooks.rs

Components Verified:

✅ Hook trait with pre_llm() and post_llm() methods
✅ HookManager with hook registration and execution
✅ HookDecision enum (Allow, Block, Modify, AskUser)
✅ PreLlmContext and PostLlmContext structs
✅ Default implementations that return Allow

2.3 Guard+Replacement Flow

✅ Guard Stage Documentation

File: .docs/runtime-validation-hooks.md:9-34

Guard Logic Verified:

#!/bin/bash
# Extract command from JSON input
COMMAND=$(echo "$1" | jq -r '.tool_input.command // empty')

# Strip quoted strings to avoid false positives
CLEAN_COMMAND=$(echo "$COMMAND" | sed 's/"[^"]*"//g')

# Check for dangerous bypass flags
if [[ "$CLEAN_COMMAND" =~ (--no-verify|-n)(?=.*\bgit\s+(commit|push)) ]]; then
    # Return deny decision
    echo '{"decision": "deny", "reason": "Git bypass flags detected"}'
    exit 0
fi

# Continue to replacement stage
cd ~/.config/terraphim
terraphim-agent hook "$1"

Design Decision Tracing:

// Design Decision: Preserve guard stage for --no-verify
// Implementation: Documented in .docs/runtime-validation-hooks.md
// Actual shell hook expected at ~/.claude/hooks/pre_tool_use.sh

✅ Replacement Stage Documentation

File: .docs/runtime-validation-hooks.md:41-75

Replacement Flow Verified:

✅ Knowledge graph replacements via rolegraph.apply_replacements()
✅ Connectivity validation via automata.validate_connectivity()
✅ Thesaurus and autocomplete for consistency

2.4 CI Integration

✅ Performance Benchmarking Workflow

File: .github/workflows/performance-benchmarking.yml

Workflow Features:

✅ Triggers on workflow_dispatch, PR, and push
✅ Baseline comparison support
✅ Artifact caching for dependencies
✅ System dependencies installation
✅ Configurable iterations

Design Decision Tracing:

# Design Decision: CI & Release Validation Entry
# Implementation: .github/workflows/performance-benchmarking.yml
# with baseline_ref and iterations parameters
