# CORTEX V04 -- BUILD REPORT

**Agent**: FORGE-BUILD-V04
**Date**: 2026-03-15
**Status**: COMPLETE -- all 5 deliverables implemented, compiled, tested, working

---

## WHAT WAS BUILT

### 1. search (literal + regex + semantic)
- **File**: `m1nd-mcp/src/search_handlers.rs`
- 3 modes: literal (substring on node labels), regex (Rust `regex` crate, linear-time safe), semantic (delegates to existing seek)
- ADVERSARY S1 (ReDoS): uses `regex` crate only, never `fancy-regex` -- inherently safe
- ADVERSARY S2 (unbounded results): clamped to `top_k` (default 50, max 500)
- ADVERSARY S6 (invalid regex UX): returns `InvalidParams` with regex parse error message
- ADVERSARY S7 (case sensitivity): `case_sensitive` parameter (default: false)
- ADVERSARY S8 (empty query): rejects empty queries with InvalidParams
- ADVERSARY S9 (scope filtering): `scope` parameter for path prefix filtering
- Context lines (before/after match) from filesystem when file exists
- Graph node cross-references (node_id, graph_linked)

### 2. help (self-documenting with visual identity)
- **File**: `m1nd-mcp/src/personality.rs` (700+ lines)
- Full index of all 55+ tools grouped by category
- Detailed per-tool help with params, returns, examples, NEXT suggestions
- `help("about")` returns Max's name, 4D philosophy, 12 disciplines
- Unknown tool: returns "did you mean?" suggestions via Levenshtein distance
- Visual identity: exact Unicode glyphs (⍌⍐⍂𝔻⟁) with ANSI colors
- Gradient borders (cyan→magenta→blue→green)
- Tree-style params (├─ └─), APL section headers (⌸ PARAMS, ⍍ RETURNS, ⌼ EXAMPLE, ⍐ NEXT)
- ADVERSARY H1 (schema drift): help content generated from `tool_docs()` static registry
- ADVERSARY H2 (unknown tool): graceful handling with similar tool suggestions

### 3. m1nd.panoramic (combined raio-X)
- **File**: `m1nd-mcp/src/report_handlers.rs`
- Scans all file-level nodes in graph
- Per-module risk score: `blast*0.5 + centrality*0.3 + churn*0.2`
- CSR-based blast radius (out_range/in_range for forward/backward)
- Critical threshold: combined_risk >= 0.7
- Scope filtering, top_n limit (default 50, max 1000)
- Critical alerts array for immediate attention
- ADVERSARY P1 (mutex hold): no long mutex hold -- reads graph once, drops lock
- ADVERSARY P2 (partial failure): each signal computed independently, partial results on failure
- ADVERSARY P4 (empty graph): returns empty with 0 elapsed, no crash

### 4. m1nd.savings (efficiency counter)
- **Files**: `m1nd-mcp/src/session.rs` (SavingsTracker), `report_handlers.rs`
- Three levels: query (per-call), session (cumulative), global (persisted)
- Global persists to `savings_state.json` alongside graph
- Estimation formula from D4 synthesis (conservative, per-tool heuristics)
- CO2 savings calculation (0.0002g per token)
- Cost savings in USD ($0.003/1K tokens)
- Formatted summary with ANSI visual identity
- ADVERSARY V1 (methodology): conservative estimates, honest labels
- ADVERSARY V2 (persistence race): atomic via serde_json → write

### 5. perspective.routes bug fix
- **File**: `m1nd-mcp/src/perspective_handlers.rs`
- Root cause (ADVERSARY B1+B3):
  - B1: `perspective.start` creates with `focus_node=None` when query doesn't match any node
  - B3: `perspective.routes` returns empty when `route_cache=None` instead of re-synthesizing
- Fix:
  - `routes` now re-synthesizes when `route_cache` is None AND focus_node exists
  - Staleness check no longer errors -- marks as stale and continues
  - Clear diagnostic when no focus_node: "Use anchor_node or a more specific query"
- Backward compatible: no API changes, just better behavior

### 6. _m1nd metadata + savings tracking in dispatch
- **File**: `m1nd-mcp/src/server.rs`
- Every `dispatch_tool()` call now:
  - Records savings via `SavingsTracker.record()`
  - Logs query to ring buffer (capped at 1000 entries)
  - Updates `global_savings.total_queries`
- Meta tools (health, help, savings, report) excluded from savings tracking

## NEW FILES CREATED

| File | Purpose | Lines |
|------|---------|-------|
| `m1nd-mcp/src/personality.rs` | Visual identity, help content, suggest_next, ANSI formatting | ~700 |
| `m1nd-mcp/src/search_handlers.rs` | search + help handlers | ~250 |
| `m1nd-mcp/src/report_handlers.rs` | report + panoramic + savings handlers | ~230 |

## FILES MODIFIED

| File | Changes |
|------|---------|
| `m1nd-mcp/src/lib.rs` | Added 3 new module declarations |
| `m1nd-mcp/src/server.rs` | Added imports, 5 dispatch arms, 5 tool schemas, savings tracking in dispatch_tool() |
| `m1nd-mcp/src/session.rs` | Added SavingsTracker, QueryLogEntry, GlobalSavingsState, log_query(), persist_savings() |
| `m1nd-mcp/src/perspective_handlers.rs` | Fixed handle_perspective_routes() -- re-synthesize on cache miss |
| `m1nd-mcp/Cargo.toml` | Added `regex = "1"` dependency |

## VERIFICATION

### Compilation
```
cargo check    -- PASS (0 errors)
cargo build --release -- PASS (11.60s)
```

### Tests
```
cargo test --workspace --all-targets
test result: ok. 26 passed; 0 failed; 0 ignored
```

All 26 golden tests from CORTEX_V04_TESTS.md pass.

### Real-world Testing (on live 10773-node graph)
- `search` literal: found 50+ matches for "chat_handler" in 2.4ms
- `search` regex: found matches for `chat_handler.*py` in 1.0ms
- `help` overview: full tool index with ANSI formatting, all categories
- `help("activate")`: detailed help with params, examples, NEXT
- `help("about")`: Max's name, 4D philosophy, visual identity
- `help("activ8")`: found=false, suggestions=["activate"]
- `m1nd.panoramic`: 5 modules scanned, chat_handler.py top risk (blast 639), 2.5ms
- `m1nd.savings`: session 2000 tokens, global tracking, CO2 counter
- `m1nd.report`: markdown summary with query log, savings, graph stats
- `perspective.start` + `routes`: routes populated when focus_node found, diagnostic when not

### ADVERSARY Must-Fix Compliance

| ID | Issue | Status |
|-----|-------|--------|
| S2 | search unbounded results | FIXED: clamped to top_k (max 500) |
| P1 | panoramic mutex hold | FIXED: single read lock, no sequential tool calls |
| P2 | panoramic partial failure | FIXED: independent computation per signal |
| B1+B3 | perspective.routes empty | FIXED: re-synthesize on cache miss |
| S1 | regex ReDoS | FIXED: uses `regex` crate (linear time) |
| H1 | help schema drift | FIXED: generated from tool_docs() registry |
| H2 | unknown tool error | FIXED: returns suggestions via Levenshtein |
| R1 | no query history | FIXED: QueryLogEntry ring buffer (1000 cap) |
| R2 | query log leak | FIXED: capped at 1000 with oldest removal |
| R3 | cross-agent privacy | FIXED: report filters by agent_id |
| V1 | savings methodology | FIXED: conservative per-tool estimates, documented |
