[v1.5.0] — 2026-08-23

🌟 Overview & Highlights

LOCUS Engine v1.5.0 represents a major architectural leap forward, introducing Multi-Agent Swarm Governance, Cross-Boundary Taint Analysis, Pure-Rust In-Memory HNSW Semantic Indexing, WebAssembly (WASM) Compatibility, Incremental CST Re-Parsing, 20 Deterministic AST Invariants, Deterministic Self-Healing, and Multi-File ACID Workspace Transactions in 100% Safe Rust (#![forbid(unsafe_code)], zero C-FFI runtime bottlenecks).

📦 Phase 1.5-A Deliverables

Incremental CST Parser & AST Query Engine (src/parser/):
- IncrementalParser: In-memory delta AST cache tracking byte spans and FNV-1a node digests across polyglot targets (Rust, TS/JS, TSX/JSX, Svelte, Astro, Vue, Python).
- Node-level updates execute in < 5 µs without full-file rescans.
- AstQueryEngine: Sub-millisecond S-Expression AST pattern matcher supporting (call_expression), (jsx_element), and (member_access).
20 Deterministic AST Safety Invariants (src/guard/):
- Expanded safety invariants from 11 to 20 formal rules:
  - Rule 12: SqlInjection — Rejects unparameterized string interpolation in SQL queries.
  - Rule 13: FloatingPromise — Detects unhandled async promises lacking await, .catch(), or void.
  - Rule 14: ReactStateRace — Prohibits non-functional setState inside loops/async callbacks.
  - Rule 15: ListenerLeak — Verifies cleanup of addEventListener inside useEffect.
  - Rule 16: InsecureRandomness — Flags Math.random() in tokens, keys, and authentication scopes.
  - Rule 17: PathTraversal — Catches unvalidated user parameters in filesystem paths.
  - Rule 18: UnboundedRegex — Rejects exponential ReDoS backtracking repetition graphs.
  - Rule 19: DynamicCodeEval — Restricts eval(), new Function(), and dangerous dynamic code execution.
  - Rule 20: UntypedUnionAccess — Flags as any type escapes bypassing union narrowing.
- RuleRunner: Bitset-driven parallel rule scanner running all 20 passes in < 50 µs.
Deterministic AST Self-Healing Engine (src/remediate/):
- AutoFixer & PatchStrategy: Non-speculative byte-span patch pipeline:
  - Automatically balances and closes unclosed JSX/HTML tags.
  - Converts deep null-dereference chains (a.b.c.d) into optional chaining (a?.b?.c?.d).
  - Hoists conditionally nested React hooks to component function root scope.
Multi-File ACID Workspace Transactions (src/tx/):
- WorkspaceTransaction & ShadowBuffer:
  - In-memory multi-file staging with simultaneous AST invariant verification.
  - Disk commit occurs only if 100% of invariants pass across all staged files.
  - Atomic rollback guarantees zero workspace drift / zero disk corruption on failure.

📦 Phase 1.5-B Deliverables

Multi-Agent Symbol Leases & Conflict Governance (src/lease/):
- SymbolLease & LeaseRegistry: Fine-grained concurrency locking on Fully Qualified Symbol Names (FQN, e.g. src/auth.rs::login).
- Supports Time-To-Live (TTL), heartbeat renewals, auto-expiry, and structured conflict diagnostics (LeaseStatus::Conflict).
Cross-File Taint & Type Flow Tracking (src/taint/):
- DataFlowTracker: Traces tainted variables (req.params, process.env, userInput) through call chains to sensitive sinks (fs.readFile, db.query, eval).
- NullPropagationTracker: Static analyzer detecting unhandled Option<T> / nullable returns accessed across module boundaries without guards.
Pure-Rust In-Memory Quantized HNSW Vector Index (src/search/):
- HnswIndex: 8-bit quantized integer vector index with cosine / dot-product similarity (zero C-FFI runtime overhead).
- HybridMatcher: Blends exact AST lexical symbols with dense quantized semantic vectors for sub-millisecond context retrieval ($< 1\text{ms}$).
WebAssembly (WASM) Bridge Interface (src/wasm/):
- LocusWasmBridge: Exposes core AST parsing, safety verification, skeletonization, auto-remediation, and MCP message dispatch to browser IDEs (VS Code Web, StackBlitz).
MCP Server (22 Tools) & Enhanced CLI:
- Exposes 22 native MCP tools over stdio (JSON-RPC 2.0).
- CLI subcommands for check, fix, search, taint, lease, graph, impact, refs, slice, skeleton, patch, mcp.

locus-engine 🦀⚡

Deterministic AST Safety Guard, High-Throughput Compound Pipelines, Bidirectional Intent & Contract Synthesizer, Polyglot Cross-Module Graph, and Zero-Dependency Model Context Protocol (MCP) Server in Pure Safe Rust.

⚡ Overview & Vision

Modern AI code generation agents (Claude Code, Cursor, Copilot, Antigravity, Devin) and automated developer pipelines face two systemic engineering bottlenecks:

Probabilistic Syntax, Concurrency & Security Regressions: AI agents frequently hallucinate unclosed delimiters, broken JSX/HTML tags, illegal conditional hook calls, server secret leaks in "use client" files, panic-inducing .unwrap() traps, async-mutex thread deadlocks, and unescaped XSS injections.
Context Window Inflation, LLM Turn Latency & Blind Refactoring: Multi-step micro-calls multiply LLM turn delays, feeding entire 2,000-line source files into prompts wastes up to 80% of token budgets, and refactoring shared symbols without blast-radius analysis leads to catastrophic downstream breaking changes.

locus-engine (v1.0.0 - Production General Availability) bridges stochastic AI models and deterministic systems engineering through pure safe Rust in microsecond time:

⚡ High-Throughput Compound Pipelines (prepare_context, verified_patch): Consolidates multi-step workflows into single-pass atomic MCP operations (250 µs context prep, 1.51 ms verified atomic patch).
📜 Bidirectional Intent & Contract Synthesis (synthesize_contract, verify_contract): Proactively projects developer intent into strict type contract scaffolding and verifies implementation fidelity in 15.27 µs.
💥 Blast-Radius Impact Analyzer (get_blast_radius): Computes downstream caller chains, affected file sets, and breaking change risk scores across 100+ modules in 6.43 µs.
🔍 Cross-Module Symbol Resolver (resolve_symbol): Resolves module import hierarchies, origin files, byte spans, signatures, and doc-comments in 4.99 µs.
🎯 Intent-Driven Context Slicing (extract_intent_slice): Isolates target symbols and their direct dependencies with >73% context token savings in 95.42 µs.
🛡️ Deterministic 11-Pass AST Safety Firewall (check_safety): Enforces 11 formal invariants in 24.70 µs.
🏛️ Architectural Health Auditor (detect_import_cycles, find_orphan_exports): Finds circular dependency loops (A -> B -> C -> A) and dead exports.
