Implementation Spec for Issue #7: Convert researcher to Rust

Objective

Rewrite hero_researcher from TypeScript/Bun to Rust, using herolib_ai for AI calls, following hero crate workspace conventions.

Current Architecture

The existing TypeScript project is an AI-powered research assistant that:

  1. Takes a person's name/context as input (CLI or web API)
  2. Generates search queries across multiple providers (Brave, DuckDuckGo, SearXNG, Exa, Serper, SerpAPI)
  3. Scrapes web pages with 8 platform-specific scrapers
  4. Disambiguates evidence using LLM calls
  5. Synthesizes findings into reports with confidence scoring
  6. Outputs markdown, JSON, or HTML reports
  7. Provides web UI with SSE streaming and SQLite persistence

Requirements

  • Replace OpenRouterClient with herolib_ai::AiClient
  • Rust edition 2024, rust-version 1.92.0
  • Workspace layout: root Cargo.toml + crates/ directory
  • Hero conventions: buildenv.sh, Makefile, scripts/
  • All search providers ported
  • All 8 platform scrapers ported
  • CLI, web server, and report formatters ported
  • SQLite persistence via rusqlite

Workspace Structure

hero_researcher/
  Cargo.toml (workspace root)
  Makefile
  buildenv.sh
  scripts/
  crates/
    hero_researcher_lib/     (core library)
    hero_researcher_server/  (web server + DB)
    hero_researcher/         (CLI binary)

Implementation Plan (10 Steps)

Step 1: Scaffold Workspace and Build Infrastructure

Create workspace Cargo.toml, all crate Cargo.tomls, Makefile, buildenv.sh, scripts, .gitignore, minimal stubs.

Step 2: Core Types, Error Handling, and Config

Port types.ts, config.ts, validation.ts, logger.ts → error.rs, types.rs, config.rs, logger.rs

Step 3: Search Providers

Port all 6 search providers + aggregator + key rotator + factory

Step 4: Scraper and Platform Scrapers

Port generic scraper + 8 platform scrapers + evidence building

Step 5: Research Prompts and Audit Log

Port prompt templates + audit logging

Step 6: Core Researcher Logic

Port the main Researcher struct with full research pipeline using herolib_ai

Step 7: Report Formatter

Port markdown/JSON/HTML formatters

Step 8: CLI Binary

Port CLI with clap, matching current interface

Step 9: Web Server and Database

Port web server with SSE + SQLite persistence

Step 10: Testing, Documentation, and Cleanup

Tests, docs, README, remove TypeScript files

Acceptance Criteria

  • cargo check --workspace passes
  • cargo test --workspace passes
  • Uses herolib_ai::AiClient for all LLM calls
  • All search providers work
  • All platform scrapers work
  • CLI and web server functional
  • Reports in all 3 formats
  • Hero crate conventions followed
  • TypeScript files removed

Notes

  • herolib_ai is sync (ureq-based, no tokio) — use thread pools for concurrency
  • Use AiClient::chat_raw() for arbitrary OpenRouter model IDs
  • rusqlite with bundled feature for SQLite (matches hero_code_indexer pattern)

Updated Implementation Spec for Issue #7: Convert researcher to Rust

Updated Plan — Added Phase 0: Expand herolib_ai

Based on gap analysis, herolib_ai at /Volumes/T7/code0/hero_lib/crates/ai needs the following additions before we can port hero_researcher:

Critical Gaps to Fix in herolib_ai:

  1. Missing Claude models — Add Claude Opus 4.6, Claude Sonnet 4.5 to Model enum (needed for synthesis phase)
  2. Missing Gemini models — Add Gemini 3 Flash Preview, Gemini 3 Pro Preview (needed for extraction)
  3. Custom/passthrough model support — Allow arbitrary string model IDs for OpenRouter (hero_researcher uses 15+ models)
  4. Online mode — Support :online suffix for models that support online search
  5. Structured JSON output — Add response_format support for JSON mode
  6. Rate limiting — Add token bucket rate limiter (60 RPM default)

What herolib_ai already supports (no changes needed):

  • Chat completions with system + user messages ✓
  • Temperature and max_tokens control ✓
  • PromptBuilder with retry logic ✓
  • Multi-provider failover (DeepInfra, Groq, OpenRouter, SambaNova) ✓
  • Token tracking in responses ✓
  • Error handling ✓

Revised 12-Step Plan

Step 0A: Add missing models to herolib_ai

Add Claude Opus 4.6, Claude Sonnet 4.5, Gemini 3 Flash Preview, Gemini 3 Pro Preview to Model enum with provider mappings. Write tests.

Step 0B: Add custom model ID support to herolib_ai

Allow passing arbitrary model ID strings (e.g., "anthropic/claude-opus-4.6") alongside the Model enum. Needed for OpenRouter's full model catalog. Write tests.

Step 0C: Add online mode support to herolib_ai

Support :online suffix for models that enable online search capability. Write tests.

Step 0D: Add structured JSON output to herolib_ai

Add response_format parameter support for JSON mode output. Write tests.

Step 0E: Add rate limiting to herolib_ai

Token bucket rate limiter, configurable RPM (default 60). Write tests.

Steps 1-10: Same as original spec

  1. Scaffold Workspace and Build Infrastructure
  2. Core Types, Error Handling, and Config
  3. Search Providers (6 providers + aggregator + key rotator)
  4. Scraper and Platform Scrapers (8 scrapers)
  5. Research Prompts and Audit Log
  6. Core Researcher Logic (using expanded herolib_ai)
  7. Report Formatter (markdown/JSON/HTML)
  8. CLI Binary (clap)
  9. Web Server and Database (SQLite)
  10. Testing, Documentation, and Cleanup

Key Change

All herolib_ai improvements (Steps 0A-0E) will be done first with independent tests, in the hero_lib repo. Then hero_researcher conversion (Steps 1-10) proceeds using the expanded AI client.
