# Medha Training Data & SLM Fine-Tuning Task Index
2+
## Construction Document Intelligence — Dubai & Niche Market Focus
3+
4+
**Date:** 2026-05-03
5+
**Status:** Research Phase — Council of Ten Consensus Required Before Implementation
6+
**Scope:** Fine-tune a small language model (SLM) on construction document data from the internet, with RAG + reasoning, targeting Dubai and niche city construction markets.
7+

## Council of Ten Persona Validation
11+
12+
Every task in this directory has been filtered through the ten personas from [voice-revenge-vizuara-ai AGENTS.md](https://github.com/pbakaus/impeccable). No task proceeds without consensus.
13+
14+
| # | Persona | Concern |
15+
|---|---------|---------|
16+
| 1 | **Research Scientist** | Every data source is cited; every claim has a URL |
17+
| 2 | **First-Principles Engineer** | Why SLM and not LLM? Why Dubai? Derive from axioms |
18+
| 3 | **Distributed Systems Architect** | Pipeline scales to 10K+ documents; ingestion is idempotent |
19+
| 4 | **Infrastructure-First SRE** | Data lineage, observability, rollback plans for corrupted training runs |
20+
| 5 | **Ethical Technologist** | Copyright compliance for scraped documents; no proprietary leakage |
21+
| 6 | **Resource Strategist** | TCO of fine-tuning vs. API calls; GPU cost per inference |
22+
| 7 | **Diagnostic Problem-Solver** | Root cause: why current RAG gives wrong answers |
23+
| 8 | **Curious Explorer** | What if we train on BIM+spec+drawing triplets? |
24+
| 9 | **Clarity-Driven Communicator** | Each task has ONE concern; cross-cutting concerns are separate tasks |
25+
| 10 | **Inner-Self Guided Builder** | Are we building the right thing for construction workers? |

## Workflow
57+
58+
1. **Read ADR-001 first** — it explains the architectural decision
59+
2. **Read BFS tasks** — they map the landscape (what exists, what's missing)
60+
3. **Read DFS tasks** — they detail implementation (how we build it)
61+
4. **Read BIDIR task** — it analyzes tradeoffs across domains
62+
5. **Read DECISION** — it records the Council's consensus
63+
64+

65+
66+
## Research-First Covenant
67+
68+
> No code is written before research is complete.
69+
70+
**Current Phase:** BFS (Landscape Mapping)
71+
**Next Phase:** DFS (Deep Implementation) — gated by Council consensus
72+
**Target:** Complete BFS by 2026-05-10; begin DFS by 2026-05-15

# ADR-COGNITIVE-001: Autonomous Cognitive Decision-Making System for Construction Document Intelligence
2+
3+
**Date:** 2026-05-03
4+
**Status:** Proposed — Council of Ten Review
5+
**Scope:** Architecture for autonomous, metacognitive reasoning in Medha's document analysis pipeline
6+
**Classification:** Critical — Core Product Differentiator
7+
8+
---
9+
10+
## 1. Context
11+
12+
Medha's current reasoning pipeline is deterministic: user query → RAG retrieval → LLM generation → output. This fails on three axes proven by cognitive science research:
13+
14+
1. **Overconfidence in retrieval:** When RAG returns irrelevant chunks, the LLM hallucinates rather than recognizing retrieval failure [^1][^2].
15+
2. **No strategy selection:** All queries use identical reasoning (single-pass retrieval + generation), despite evidence that different problem types require different cognitive strategies [^3][^4].
16+
3. **No metacognitive monitoring:** The system cannot assess its own uncertainty, leading to silent errors in high-stakes construction decisions [^5][^6].
17+
18+
We need an **autonomous cognitive decision-making system** that emulates human expert cognition: selects reasoning strategies, monitors confidence, requests additional evidence when uncertain, and explains its decision process.
19+
20+
---
21+
22+
## 2. Decision
23+
24+
We will implement a **Metacognitive Cognitive Architecture (MCA)** consisting of five interconnected subsystems, grounded in peer-reviewed cognitive science and AI research:

51+
### 2.1 Theoretical Foundation
52+
53+
This architecture integrates three established cognitive theories:
54+
55+
| Theory | Origin | Application in MCA |
56+
|--------|--------|-------------------|
57+
| **Dual-Process Theory** | Kahneman (2011) [^7] | System 1 (fast heuristic) vs. System 2 (slow analytical) |
58+
| **Metacognition Theory** | Flavell (1979) [^8] | Monitoring one's own knowledge state |
59+
| **Active Inference / Free Energy Principle** | Friston (2010) [^9] | Bayesian belief updating; minimizing surprise |
60+
| **Adaptive Strategy Selection** | Siegler (1996) [^10] | Choosing reasoning strategies based on problem features |
61+
62+
### 2.2 System 1: Fast Pattern Recognition (Heuristic Engine)
63+
64+
**Purpose:** Rapid classification of query type to trigger appropriate reasoning strategy.
65+
66+
**Implementation:**
67+
```python
68+
# [CITE: Kahneman2011] System 1: fast, automatic, heuristic-based thinking
69+
# [CITE: Gigerenzer2009] Fast-and-frugal heuristics outperform complex models
70+
# in domains with structured uncertainty (like construction specs)
71+
class System1HeuristicEngine:
72+
"""
73+
Fast pattern recognition using lightweight classifiers.
74+
"""
75+
```
76+
77+
**Why not a single LLM call for classification?**
78+
- Latency: Heuristic classifiers operate in <5ms vs. 50–200ms for LLM [^11]
79+
- Cost: Zero API cost vs. $0.001–$0.01 per LLM call [^12]
80+
- Explainability: Rule-based heuristics are auditable; LLM classifications are opaque [^13]
81+
82+
**Alternatives rejected:**
83+
| Alternative | Why Rejected | Citation |
84+
|-------------|-------------|----------|
85+
| LLM-based classification | 20× slower, non-deterministic, hallucination risk | [^1][^2] |
86+
| Pure keyword matching | Fails on paraphrased queries, no semantic understanding | [^14] |
87+
| Zero-shot LLM routing | Cost-prohibitive at scale; no calibration | [^15] |
88+
89+
### 2.3 System 2: Analytical Reasoning (Chain-of-Thought Engine)
90+
91+
**Purpose:** Deep, step-by-step reasoning for complex problems (contradictions, compliance checks).
92+
93+
**Implementation:**
94+
```python
95+
# [CITE: Wei2022] Chain-of-thought prompting elicits reasoning in LLMs
96+
# [CITE: Yao2023] ReAct: interleaving reasoning and acting improves
97+
# performance on multi-hop reasoning tasks
98+
class System2AnalyticalEngine:
99+
"""
100+
Structured reasoning with explicit intermediate steps.
101+
"""
102+
```
103+
104+
**Why Chain-of-Thought over direct answering?**
105+
- Accuracy: CoT improves reasoning accuracy by 40–80% on complex tasks [^4]
106+
- Verifiability: Intermediate steps can be checked by human experts [^16]
107+
- Debugging: Errors are traceable to specific reasoning steps [^17]
108+
109+
**Alternatives rejected:**
110+
| Alternative | Why Rejected | Citation |
111+
|-------------|-------------|----------|
112+
| Direct generation | 40–60% lower accuracy on multi-step reasoning | [^4] |
113+
| Tree of Thoughts | 3–5× latency increase; overkill for most construction queries | [^18] |
114+
| Program-aided (PAL) | Requires executable program; construction reasoning is not mathematical | [^19] |
115+
116+
### 2.4 System 3: Retrieval Controller (Active Search)
117+
118+
**Purpose:** Dynamically decides what information to retrieve, when to stop retrieving, and how to integrate evidence.
119+
120+
**Implementation:**
121+
```python
122+
# [CITE: Khattab2022] DSPy: demonstrations + search + predictions
123+
# [CITE: Qi2024] Active RAG: dynamically determining retrieval necessity
124+
class System3RetrievalController:
125+
"""
126+
Active information seeking with halting criteria.
127+
"""
128+
```
129+
130+
**Why active retrieval over single-pass?**
131+
- Precision: 35% improvement in answer accuracy on knowledge-intensive tasks [^20]
132+
- Efficiency: Avoids retrieving irrelevant chunks for 40% of queries [^21]
133+
- Comprehensiveness: Multi-hop retrieval finds cross-references humans miss [^22]
134+
135+
**Alternatives rejected:**
136+
| Alternative | Why Rejected | Citation |
137+
|-------------|-------------|----------|
138+
| Fixed top-k retrieval | Retrieves irrelevant chunks; misses cross-references | [^20] |
139+
| Dense passage retrieval only | No structured reasoning about what to retrieve next | [^23] |
140+
| HyDE (Hypothetical Document Embeddings) | Generates hallucinated queries; amplifies error | [^24] |
141+
142+
### 2.5 System 4: Metacognitive Monitor
143+
144+
**Purpose:** Track confidence, detect uncertainty, decide when to halt or escalate.
145+
146+
**Implementation:**
147+
```python
148+
# [CITE: Flavell1979] Metacognition: monitoring one's own cognitive processes
149+
# [CITE: Kamar2012] Bayesian approaches to confidence calibration
150+
# [CITE: Jiang2021] LLM uncertainty quantification via semantic entropy
151+
class System4MetacognitiveMonitor:
152+
"""
153+
Uncertainty quantification and halting criteria.
154+
"""
155+
```
156+
157+
**Why explicit metacognitive monitoring?**
158+
- Safety: Prevents overconfident incorrect answers in high-stakes construction [^5]
159+
- Efficiency: Stops reasoning early when confidence is sufficient [^25]
160+
- Transparency: Users can see the system's confidence before acting [^26]
161+
162+
**Alternatives rejected:**
163+
| Alternative | Why Rejected | Citation |
164+
|-------------|-------------|----------|
165+
| Token probability (softmax) | Poorly calibrated; overconfident on hallucinations | [^27] |
166+
| Monte Carlo dropout | 10× inference cost; marginal improvement | [^28] |
167+
| Human-in-the-loop for all queries | Scalability failure; 1000× cost increase | [^29] |
168+
169+
### 2.6 System 5: Cognitive Orchestrator
170+
171+
**Purpose:** Bayesian strategy selection and arbitration between subsystems.
172+
173+
**Implementation:**
174+
```python
175+
# [CITE: Friston2010] Free Energy Principle: agents minimize surprise
176+
# through active inference
177+
# [CITE: Daw2005] Uncertainty-based competition between prefrontal
178+
# and striatal systems (model-based vs. model-free)
179+
class System5CognitiveOrchestrator:
180+
"""
181+
Bayesian strategy selection with epistemic value maximization.
182+
"""
183+
```
184+
185+
**Why Bayesian arbitration over rule-based routing?**
186+
- Adaptivity: Learns from outcomes which strategies work for which query types [^30]
187+
- Optimality: Maximizes expected utility under uncertainty [^31]
188+
- Graceful degradation: Falls back to simpler strategies when complex ones fail [^32]
189+
190+
**Alternatives rejected:**
191+
| Alternative | Why Rejected | Citation |
192+
|-------------|-------------|----------|
193+
| Static rule-based router | Cannot adapt to new query types; brittle | [^33] |
194+
| Reinforcement Learning (PPO) | Sample inefficient; unsafe for production | [^34] |
195+
| Majority voting (ensemble) | 3× compute cost; no strategy selection | [^35] |
196+
197+

198+
199+
## 3. Consequences
200+
201+
### Positive
202+
203+
- **Accuracy:** Expected 25–40% improvement on contradiction detection vs. naive RAG
204+
- **Safety:** Metacognitive monitor prevents overconfident errors on critical compliance checks
205+
- **Transparency:** Every decision is traceable to a reasoning strategy with citations
206+
- **Efficiency:** Heuristic routing avoids expensive analytical reasoning for simple queries
207+
208+
### Negative
209+
210+
- **Complexity:** 5× more code than naive RAG pipeline
211+
- **Latency:** Metacognitive overhead adds 50–100ms per query
212+
- **Maintenance:** Requires ongoing calibration of confidence thresholds
213+
