## 1. LaTeX & Title Issues

### I-01: Title extraction fails on `##` headings (FIXED)
- **Severity**: High
- **Status**: FIXED — v9 patch
- **Root Cause**: `_extract_paper_title()` in `executor.py:242` only matched `# ` (H1). When LLM generates `## Title ...` (H2), no candidates were found → returned `"Untitled Paper"`.
- **Affected Runs**: Run 12 (`\title{Untitled Paper}`)
- **Files**:
  - `researchclaw/pipeline/executor.py:240-253` — regex now matches `#{1,2}`, strips "Title " prefix
  - `researchclaw/templates/converter.py:429-451` — `_extract_title()` now handles level 1 and 2
- **Fix**: Added H2 fallback; handles `## Title <actual title>` pattern by stripping literal "Title " prefix.

### I-02: Converter `_extract_title` also level-1 only (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9 patch (same fix as I-01)
- **File**: `researchclaw/templates/converter.py:434,442,447` — `sec.level in (1, 2)` + "Title " prefix strip
- **Note**: Both I-01 and I-02 fixed together.

### I-03: LaTeX outer fence not stripped (FIXED)
- **Severity**: High
- **Status**: FIXED — commit `3792fd6`
- **File**: `converter.py:107-117`
- **Fix**: Greedy regex + boundary strip

### I-04: Metric values 16 decimal places (FIXED)
- **Severity**: Medium
- **Status**: FIXED — commit `3792fd6`
- **File**: `converter.py:119-133`
- **Fix**: `_round_raw_metrics()` rounds to 4 places

### I-05: Duplicate tables in LaTeX output (FIXED)
- **Severity**: Medium
- **Status**: FIXED — IMP-30, commit `b88aba2`
- **File**: `converter.py:542-575`
- **Fix**: `_deduplicate_tables()` by header row matching

---

## 2. Experiment Quality Issues

### I-06: Experiments only run n=1 seeds (FIXED)
- **Severity**: High
- **Status**: FIXED — v9 patch
- **Evidence**: Run 11 (n=1), Run 12 (n=1), Run 13 (n=1)
- **Root Cause**: Time budget pressure + weak enforcement in prompts.
- **Fix**: Added `multi_seed_enforcement` block in `prompts.py` with mandatory implementation pattern (3-5 seeds), adaptive seed count, and concrete code template. Injected into code_generation for all sandbox/docker experiments via `executor.py`.
- **Files**: `prompts.py` (new `multi_seed_enforcement` block), `executor.py:2145-2149`

### I-07: Ablation methods produce identical outputs (FIXED)
- **Severity**: High
- **Status**: FIXED — v9.1 patch
- **Evidence**: Run 12 — ablation checker flagged many identical conditions
- **Files**:
  - `executor.py:3838-3866` — identical condition detection (WORKS)
  - `executor.py:3876+` — zero-variance detection across all conditions (NEW)
  - `validator.py:607-658` — deep AST ablation override check (NEW)
  - `prompts.py:969+` — stronger ablation guidance
- **Fix**: Added Check 5 in `validate_experiment_classes()` — compares AST dumps of overridden methods between child and parent classes. If all overrides are identical AST, warns that ablation is fake. Also added R13-1 zero-variance detection in executor analysis stage.

### I-08: RL training steps insufficient (FIXED)
- **Severity**: High
- **Status**: FIXED — v9 patch
- **Evidence**: Run 13 PPO/SAC/TD3 all near-zero reward after 60k steps
- **Root Cause**: RL algorithms need 500k-1M+ steps for MuJoCo tasks
- **Fix**: Added `rl_step_guidance` block in `prompts.py` with per-algorithm minimum steps table (PPO MuJoCo: 500K min / 1M-3M recommended, SAC/TD3: 300K min, etc.), step budget allocation strategy, and evaluation protocol. Auto-detected via topic keywords and injected into both experiment_design and code_generation prompts.
- **Files**: `prompts.py` (new `rl_step_guidance` block), `executor.py:2161-2174` (code_gen), `executor.py:1960-1963` (exp_design)

### I-09: All experiment methods fail (zero metrics) (FIXED)
- **Severity**: Critical
- **Status**: FIXED — Run 7-10 all had this, Runs 11-12 improved
- **Fixes applied**: Docker deps (commit `787172d`), training epochs (commit `787172d`), anti-simulation rules (commit `44151b1`)
- **Verification**: Run 11 still has 0 metrics (QLoRA instability), Run 12 has valid metrics

### I-10: `.ptp()` NumPy 2.0 API removed (FIXED)
- **Severity**: High
- **Status**: FIXED — commit `44151b1`
- **File**: `validator.py` — forbidden patterns detection
- **Fix**: Detect and replace deprecated NumPy APIs before execution

### I-11: Experiment results not framed correctly in paper (FIXED)
- **Severity**: Medium
- **Status**: FIXED — IMP-10 contradiction detection
- **File**: `executor.py:_detect_result_contradictions()`
- **Fix**: Auto-frames null results, warns about negative results

## 3. Code Generation Issues

### I-12: Code too simplistic / lazy implementations (FIXED)
- **Severity**: Critical
- **Status**: FIXED — commit `cb4af26`
- **Files**: `validator.py` (AST analysis), `executor.py` (LLM code review stage 10.5)
- **Fix**: Minimum 50 lines per algorithm class, empty subclass detection

### I-13: dict[key] crashes without .get() (FIXED)
- **Severity**: Medium
- **Status**: FIXED — commit `44151b1`
- **File**: `validator.py` — forbidden patterns
- **Fix**: Detect unsafe dict access in generated code

### I-14: LLM tasks use synthetic simulation (FIXED)
- **Severity**: Critical
- **Status**: FIXED — commit `44151b1`
- **File**: `prompts.py` — CRITICAL NO SIMULATION rule
- **Fix**: Prohibit fake training loops with synthetic loss values

### I-15: Missing experiment harness integration (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9.1 patch
- **File**: `docker_sandbox.py:215-222` — `_inject_harness()`, `prompts.py:288-302` — harness guidance
- **Fix**: Changed harness from "RECOMMENDED" to "MANDATORY" in compute_budget prompt block. Added explicit `check_value()` NaN detection and `finalize()` requirement with code examples.

- **Status**: FIXED — commit `63c5a7d`
- **Files**: `arxiv_client.py` (circuit breaker), `openalex_client.py` (new), `semantic_scholar.py` (batch API)

---

## 6. Infrastructure Issues

### I-25: Docker missing ML packages (FIXED)
- **Status**: FIXED — transformers, peft, trl, bitsandbytes, MuJoCo, etc.
- **Commits**: `e72a818`, `787172d`

---

## 7. Pipeline Logic Issues

### I-30: Pipeline proceeds after MAX_DECISION_PIVOTS=2 — quality gate added (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9.1 patch (quality gate added, MAX_PIVOTS=2 kept by design)
- **Files**: `runner.py:299-321` — quality gate check, `runner.py:697-756` — `_check_experiment_quality()`
- **Fix**: Added `_check_experiment_quality()` function that runs before forced PROCEED. Checks: (1) all metrics zero, (2) all conditions identical primary_metric (R13-1), (3) too many ablation warnings, (4) analysis quality score < 3. If any check fails, writes `quality_warning.txt` to run directory and logs QUALITY WARNING. Pipeline still proceeds but the warning is preserved for review.

### I-31: LLM code review JSON parsing failure (FIXED)
- **Status**: FIXED — commit `44151b1`
- **File**: `executor.py:2300-2330`
- **Fix**: Markdown fence stripping, graceful fallback

### I-32: Topic quality not validated against trends (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9.1 patch
- **File**: `prompts.py:986-996` — topic_init prompt
- **Fix**: Added TREND VALIDATION requirement to topic_init prompt: must identify 2-3 recent papers (2024-2026) for relevance, name specific benchmark/dataset, state SOTA results, and include a 'Benchmark' subsection.

## 8. New Feature Requests

### F-01: Training Framework Documentation Retrieval (FIXED — Phase 1)
- **Severity**: High — impacts LLM fine-tuning code quality
- **Status**: FIXED (Phase 1: static docs) — v9 patch
- **Description**: When the pipeline needs to generate code using training frameworks (LlamaFactory, TRL, Axolotl), the backbone LLM may not know the correct API usage. The pipeline should:
  1. Detect which framework is needed based on the experiment design
  2. Fetch the framework's official API documentation and example code
  3. Inject relevant documentation into the code generation prompt
  4. Generate code that correctly uses the framework APIs
- **Current Problem**: Generated training code may use incorrect or outdated API calls, leading to experiment failures (e.g., Run 11 QLoRA training diverged)
- **Proposed Approaches**:
  - **Option A: Static doc snippets** — Bundle curated API reference snippets for common frameworks in `researchclaw/data/framework_docs/`. Simple, fast, but requires manual updates.
  - **Option B: Context7-style MCP** — Use Context7 (upstash/context7) to fetch live documentation at runtime via MCP protocol. Always up-to-date, but adds network dependency.
  - **Option C: Git clone + extract** — Clone framework repos at pipeline startup, extract README/docs/examples, summarize via LLM, inject into prompts. Most complete, but slow and requires network.
  - **Option D: Hybrid** — Bundle static docs for top frameworks + fallback to web fetch for unknown ones.
- **Reference Tools**: Cursor `@Docs`, Context7 MCP, Aider web context, OpenHands SDK
- **Target**: Phase 4 or Phase 5
- **Dependencies**: Network access during code generation stage

### F-01 Detailed Design: Framework Doc-RAG

#### Problem Statement

When the pipeline generates experiment code that uses ML training frameworks (LlamaFactory, TRL, Axolotl, transformers Trainer), the backbone LLM (GPT-5.1/GPT-4.1) may not know current API signatures, default parameters, or correct usage patterns. This leads to:

1. **Incorrect API calls** — using removed or renamed functions
2. **Missing config fields** — e.g. LlamaFactory YAML missing required keys
3. **Wrong training patterns** — e.g. calling `Trainer.train()` without `TrainingArguments`
4. **Version mismatch** — framework APIs change between versions installed in Docker vs LLM training data

Evidence: Run 11 (QLoRA) — all 8 methods diverged; likely caused by incorrect training setup.

#### Industry Survey

| Tool | Approach | Pros | Cons |
|------|----------|------|------|
| **DocPrompting** (ICLR 2023) | BM25/dense retrieval over docs → inject into code gen prompt | Academic validation (+2.85% pass@1), open source | Requires pre-built index |
| **Cursor @Docs** | User adds doc URLs, IDE crawls/indexes, injects relevant snippets into LLM context | Real-time, version-aware | Requires IDE, manual URL management |
| **Context7 MCP** | MCP server with 9000+ pre-indexed libraries, `resolve-library-id` + `query-docs` tools | Automatic, 9k libraries, version-specific | Network dependency, closed backend |
| **DSPy DocLearner** | BeautifulSoup scraper → LLM analysis → code generation chain | Fully automated pipeline | Slow, brittle scraping |
| **llms.txt** | Standardized `/llms.txt` markdown file in project root for LLM consumption | Simple, no crawling needed | Requires framework authors to adopt |
| **AI Scientist v2** | No templates, relies purely on LLM knowledge + tree search debugging | Zero setup | Lower success rate, no doc awareness |
| **Continue + MCP** | DeepWiki for GitHub repos + Context7 for docs + `.continue/rules` | Extensible MCP ecosystem | Complex setup |
| **AGENTS.md** | Project-level instructions for AI agents (60k+ projects adopted) | No infra needed | Only project conventions, not API docs |

**Key finding**: No existing autonomous research agent (AI Scientist v1/v2, CodeScientist) dynamically reads documentation at runtime. They all rely on pre-built templates or LLM training data. **Doc-RAG would be a differentiating feature for AutoResearchClaw.**

**Academic evidence**: IBM study shows well-structured documentation improves AI response accuracy by up to **47%**.

#### Available Framework Documentation

| Framework | Docs URL | Format | Key Content |
|-----------|----------|--------|-------------|
| **TRL** | `huggingface.co/docs/trl` | HTML/MD | SFTTrainer, DPOTrainer, GRPOTrainer, RewardTrainer |
| **LlamaFactory** | `llamafactory.readthedocs.io` | HTML/RST | YAML config, CLI, SFT/DPO/RLHF/KTO/ORPO |
| **Axolotl** | `docs.axolotl.ai` | HTML/MD | YAML config, LoRA/QLoRA/GPTQ, full/DPO/GRPO |
| **PEFT** | `huggingface.co/docs/peft` | HTML/MD | LoRA/QLoRA config, get_peft_model |
| **transformers** | `huggingface.co/docs/transformers` | HTML/MD | Trainer, TrainingArguments, AutoModel |

#### Recommended Implementation: Hybrid Static + Web Fetch

**Phase 1 (Static — immediate):**
- Create `researchclaw/data/framework_docs/` directory
- Bundle curated API snippets for top 5 frameworks:
  - `trl.md` — SFTTrainer, DPOTrainer, PPOTrainer usage + config
  - `llamafactory.md` — YAML config format, CLI usage, dataset format
  - `transformers_trainer.md` — TrainingArguments, Trainer, PEFT integration
  - `peft.md` — LoRA/QLoRA config, get_peft_model, prepare_model_for_kbit_training
  - `axolotl.md` — YAML config format, training modes
- In `executor.py:_execute_code_generation()`, detect framework from experiment design
- Inject matching doc snippet into code generation prompt as `{framework_reference}`
- **Effort**: ~4 hours, no network dependency

**Phase 2 (Web Fetch — later):**
- Add `FrameworkDocFetcher` class in `researchclaw/literature/framework_docs.py`
- On experiment_design detection of framework name:
  1. Check if `llms.txt` exists at framework's docs URL
  2. If yes, fetch and extract relevant sections
  3. If no, fall back to static bundle
- Cache fetched docs locally (`.researchclaw_cache/framework_docs/`)
- TTL: 7 days (frameworks don't change API that often)
- **Effort**: ~8 hours, requires network during code gen stage

**Phase 3 (Context7 MCP — optional):**
- Integrate Context7 MCP client for automatic library discovery
- `resolve-library-id("trl")` → `"/huggingface/trl"`
- `query-docs("/huggingface/trl", "SFTTrainer config")` → relevant docs
- Most complete solution but adds external service dependency

#### Phase 1 Implementation (COMPLETED — v9 patch)

- Created `researchclaw/data/framework_docs/` with 5 curated API reference files:
  - `trl.md` — SFTTrainer, DPOTrainer, GRPOTrainer, PPOTrainer, PEFT integration
  - `peft.md` — LoRA, QLoRA, DoRA configs, save/load, target_modules by model
  - `transformers_training.md` — TrainingArguments, Trainer, tokenization, causal LM
  - `llamafactory.md` — YAML config, CLI, dataset formats, DPO, export
  - `axolotl.md` — YAML config, dataset formats, DPO, multi-GPU
- Added `detect_frameworks()` and `load_framework_docs()` in `researchclaw/data/__init__.py`
- Injected into both `experiment_design` and `code_generation` stages in `executor.py`
- Auto-detection based on topic + hypothesis + experiment plan keywords
- Max 8000 chars for code_generation, 4000 chars for experiment_design (to avoid context overflow)

#### Integration Point in Pipeline

```
Stage 9: experiment_design → detects framework (e.g., "use TRL SFTTrainer")
                ↓
Stage 10: code_generation prompt += framework_reference doc snippet
                ↓
Stage 10.5: code_review → validates API calls against doc snippet
                ↓
Stage 12: execution → framework is already installed in Docker
```

#### Framework Detection Heuristics

```python
FRAMEWORK_KEYWORDS = {
    "trl": ["SFTTrainer", "DPOTrainer", "PPOTrainer", "trl", "RewardTrainer"],
    "llamafactory": ["LlamaFactory", "llama_factory", "llamafactory"],
    "peft": ["LoRA", "QLoRA", "get_peft_model", "PeftConfig"],
    "transformers": ["Trainer", "TrainingArguments", "AutoModelForCausalLM"],
    "axolotl": ["axolotl"],
}
```

## 9. Run 13 Findings (RL Benchmark — PPO/SAC/TD3 with PER on MuJoCo)

### R13-1: All conditions produce identical metrics (FIXED)
- **Severity**: Critical
- **Status**: FIXED — v9.1 patch
- **Evidence**: Run 13 — all 6 algorithm/PER conditions had identical primary_metric (0.1074)
- **Root Cause**: Condition → implementation mapping broken in generated code; ablation checker caught it but too late
- **Fix**: Added zero-variance detection in executor.py analysis stage (line 3876+). Added to `_check_experiment_quality()` gate in runner.py. AST validation in validator.py now catches fake ablation subclasses.

### R13-2: Gymnasium v4 environments deprecated (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9.1 patch
- **Evidence**: Run 13 warnings: "The environment HalfCheetah-v4 is out of date"
- **Fix**: Added v5 environment requirement to `rl_step_guidance` prompt block in prompts.py.

### R13-3: No learning curve logging for RL (FIXED)
- **Severity**: Medium
- **Status**: FIXED — v9.1 patch
- **Evidence**: Run 13 only reported final metrics, no step-by-step evaluation
- **Fix**: Added learning curve logging requirement to `rl_step_guidance` prompt: `EVAL:` lines every N_eval steps, `LEARNING_CURVE:` summary at end.

## 10. Feature Requests — Advanced Code Generation

### F-02: Advanced Coding Agent for Experiment Code Generation (OPEN)
- **Severity**: Critical (pipeline capability ceiling)
- **Status**: OPEN — research complete, implementation pending
- **Problem**: Current code generation stage produces relatively simple, single-file experiments. Cannot design large-scale multi-file projects (e.g., complex RL systems with custom environments, multi-component fine-tuning pipelines). This limits paper quality and experiment sophistication.
- **Goal**: Replace single-shot code generation with an agentic coding system capable of iterative development, debugging, and multi-file project design — analogous to how Claude Code or Devin can build complex projects from scratch.

#### Research Summary

**Design Patterns Identified** (from survey of 12+ systems: Claude Code, Cursor, Devin, SWE-Agent, OpenHands, Aider, MetaGPT, ChatDev, AI Scientist v2, AIDE, AgentCoder, AlphaCodium):

| Pattern | Description | Key Systems | Impact |
|---------|-------------|-------------|--------|
| A: Architect-then-Code | Separate planning step → architecture spec → code generation | Aider, MetaGPT | HIGH |
| B: Solution Tree Search | Solutions as tree nodes; branch, evaluate, prune | AI Scientist v2, AIDE | CRITICAL |
| C: Execution-in-the-Loop | Generate → execute → parse error → fix loop | Claude Code, SWE-Agent | HIGH |
| D: Multi-Agent Review | Coder + reviewer dialog with iterative refinement | ChatDev, AgentCoder | MEDIUM |
| E: Tool-Augmented Generation | File R/W, terminal, linting, search as LLM tools | Claude Code, SWE-Agent | HIGH |
| F: Context Engineering | Repo maps, compression, selective context inclusion | Aider, Claude Code | MEDIUM |

#### Implementation Plan — 4 Phases

**Phase 1: Architect-then-Code** (Priority: HIGH)
- Add architecture planning substage before code generation
- LLM produces file structure, class hierarchy, data flow diagram
- Code generation uses architecture spec as constraint
- Files: `researchclaw/pipeline/executor.py` (new substage), `researchclaw/prompts.py` (architecture prompt)

**Phase 2: Execution-in-the-Loop** (Priority: HIGH)
- After initial code generation, run code in sandbox
- Parse stderr/stdout for errors
- Feed errors back to LLM for iterative fix (max N iterations)
- Already partially exists in current REFINE loop — needs to be tightened into inner code-fix loop
- Files: `researchclaw/pipeline/executor.py`, `researchclaw/experiment/docker_sandbox.py`

**Phase 3: Solution Tree Search** (Priority: CRITICAL)
- Multiple candidate solutions generated in parallel
- Each evaluated via sandbox execution (runtime errors, metric quality)
- Best candidate selected or merged; backtrack on failures
- Inspired by AIDE/AI Scientist v2 tree search pattern
- Files: New `researchclaw/pipeline/code_agent.py`, `researchclaw/pipeline/executor.py`

**Phase 4: Multi-Agent Review** (Priority: MEDIUM)
- Coder agent generates code, reviewer agent critiques
- Dialog continues until reviewer approves or max rounds reached
- Catches logical errors, missing edge cases, poor experiment design
- Files: `researchclaw/pipeline/code_agent.py`

| T3 | Meta-Learning | GPT-5.1 (v2) | 10.0/10 | 1366 | 1140 | 9 | MAML functional_call, Reptile, ProtoNet |

**Key findings:**
- v1→v2 prompt fix: method_richness improved from 4.4/10 to 10/10 (thin wrapper elimination)
- GPT-5.1 consistently produces 1100-1250 effective lines with proper algorithmic depth
- MAML implementation uses `torch.nn.utils.stateless.functional_call` for correct second-order gradients
- SNGP implementation includes Random Fourier Features with diagonal GP posterior
- All generated code passes syntax validation; no runtime errors in static analysis

**Remaining observations (not blocking):**
- MAMLFirstOrderLearner has significant code duplication with MAMLLearner (could use flag)
- LinearClassifierHead flagged as thin (9 lines) — acceptable for utility module
- GPT-5.2 timed out on preflight check (reasoning model min 32768 tokens)
