refactor: unified weighted lexicon + centroid layer
- CryptoSentimentCalibrator: 2,086-term weighted lexicon (-100 to +100) * Priority-based span matching (longest-first, no double-count) * Whale phrases ±50, compounds ±30, dot-separated ±20, singles ±10-25 - Calibration logic: lexicon wins on disagreement, amplifies on agreement - CentroidManager: 6 params × 1024-dim built from lexicon via e5-large-v2 - ScoringEngine._refine_with_centroids: fixed attribute access bug - config/centroids/*.npy: padded to 1024-dim (e5-large-v2 output) - lexicon_weights.json: generated unified lexicon - Unit tests: 46/46 core NLP tests pass - Labeling pipeline: 22 samples processed - All 19 critical crypto semantic tests + 6 calibration scenarios pass

|
||||
|
||||
| Requirement | Spec | Implemented | Gap |
|
||||
|-------------|------|-------------|-----|
|
||||
| High-level pipeline | 7 stages (Ingest → NLP → Event → Signal → Scoring → Aggregation → Sink) | NLP → Event → Signal → Scoring → Aggregation ✅ | Missing Ingestion + Sink |
|
||||
| Ingestion Service | Kafka/Pulsar/Celery/RQ | ❌ | Not implemented |

|
||||
| Signal Processing | Event strength, velocity, decay, fusion | ✅ Core logic | Real-time streaming not implemented |
|
||||
| Scoring Engine | fear/greed/hype/pub/pump/dump | ✅ | Good |

|
||||
| Output Sink | Hazelcast ExF + ClickHouse | ❌ | Not implemented |
|
||||
| Deployment | Separate worker pool + co-located scoring | ❌ | Not deployed |
|
||||
|
||||
**Conformance:** 90% of *core* architecture present, but **ingestion and sinks are 0%**.
|
||||
|
||||

|
||||
|
||||
### 2. Ingestion Contract — Section 3
|
||||
|
||||
| Requirement | Spec | Implemented | Gap |
|
||||
|-------------|------|-------------|-----|
|
||||
| Source Categories | 9 categories (crypto news, tradfi, social, exchange, on-chain, regulatory, corporate) | ❌ | No source registry |
|
||||
| Normalized Payload Schema | 12-field JSON with engagement_metrics | ⚠️ | Schema exists but not validated |
|
||||
| Source Credibility Registry | Per-source base_credibility + decay | ✅ `source_credibility.yaml` | Registry loaded but not updated via feedback loop |
|
||||
| Poll Cadences | Defined per category | ❌ | Not implemented |
|
||||
|
||||
**Conformance:** 15% — Only the credibility registry exists.
|
||||
|
||||

|
||||
|
||||
### 3. NLP Processing Pipeline — Section 4
|
||||
|
||||
| Stage | Spec Requirement | Implemented | Gap |
|
||||
|-------|------------------|-------------|-----|
|
||||
| **4.1 Preprocessing** | HTML strip, lang detect (fasttext/CLD3), tokenization | ❌ | No preprocessing |
|
||||
| **4.2 Entity Extraction** | NER (RoBERTa), ticker regex, contract regex, alias resolution (Vitalik→ETH) | ✅ `EntityExtractor` | Uses spaCy (mock) + rule-based; alias map works |
|
||||
| **4.3 Sentiment Polarity** | FinBERT + emotion (DistilRoBERTa), prompt-based LLM fallback | ✅ `SentimentEmotionAnalyzer` | Models mock; FinBERT calibration works |
|
||||

|
||||
| **4.5 Temporal Anchoring** | HeidelTime + event-type duration priors | ✅ `TemporalAnchorer` | Basic implementation |
|
||||
| **4.6 Credibility Scoring** | Multi-factor formula (source × recency × detail × author × cross-source × engagement) | ⚠️ `CredibilityScorer` | Partial; missing detail_score, author_rep, engagement_quality |
|
||||
|
||||
**Conformance:** 60% — Pipeline structure exists; models are placeholders; event types severely limited.

|
||||
|
||||
### 4. Event Catalogue — Section 5
|
||||
|
||||

|
||||
| Tokenomics | 16 (unlock, burn, mint, inflation, etc.) | 0 | — |
|
||||
| Security & Risk | 13 (hack, exploit, audit, rug pull, etc.) | 1 (`hack`) | 12 missing |
|
||||
| Technology & Dev | 16 (mainnet, fork, upgrade, SDK, etc.) | 0 | — |
|
||||
| Governance | 10 (proposal, vote, DAO, etc.) | 0 | — |
|
||||
| Financial Performance | 19 (earnings, guidance, dividend, analyst, etc.) | 0 | — |
|
||||
| Market Structure | 24 (listing, delisting, halt, ETF, whale, etc.) | 0 | — |
|
||||
| Regulatory & Legal | 18 (ban, clampdown, SEC, EU, etc.) | 0 | — |

|
||||
| Macro | 15 (Fed, CPI, GDP, geopolitical, etc.) | 0 | — |
|
||||
| M&A | 10 (announcement, acquisition, partnership, etc.) | 0 | — |
|
||||
| **TOTAL** | **150+** | **1** | **149 missing** |
|
||||
|
||||
**Critical Gap:** Only `EventType.HACK` is implemented. The catalogue is extensible via YAML but no catalogue file exists.
|
||||
|
||||
**Conformance:** 30% (structure exists, but content is 99% missing).

|
||||
|
||||
### 5. Signal Processing Layer — Section 6
|
||||
|
||||

||||
|---------------|--------------|-------------|-----|
|
||||
| **6.1 Event Strength** | `strength = SOURCE_CRED × NUM_SOURCES × DETAIL_FACTOR`<br>SOURCE_CRED = base × recency × author_trust<br>NUM_SOURCES: cross-cluster confirmation<br>DETAIL_FACTOR: dates, amounts, addresses, names, terms, URL | ⚠️ `SignalProcessor._compute_event_strength` | Missing: author_trust, cross-cluster NUM_SOURCES, detail detector model, rumor penalty |
|
||||
| **6.2 Velocity** | hype_velocity = d(log(mentions_weighted))/dt<br>pub_velocity = d(log(pub_count))/dt<br>EMA α=0.3 | ⚠️ `VelocityComputer` | Uses simplified computation; no real sliding window |
|
||||

## Gaps Requiring Action
|
||||
|
||||
### P0 — Critical (Blockers for Production)
|
||||
1. **Ingestion Service** — No way to feed real data
|
||||
2. **Event Catalogue** — 149/150 event types missing; no YAML catalogue
|
||||
3. **Output Sinks** — No Hazelcast/ClickHouse persistence
|
||||
4. **Real Models** — All NLP models are mock/placeholder
|
||||
4. **Cross-Source Intelligence** — No NUM_SOURCES clustering, no bot detection
|
||||
5. **Deployment** — No worker pool, no co-located scoring
|
||||
|
||||
### P1 — High (Major Spec Divergence)
|
||||
6. **Event Flags Format** — Missing FLAG_TYPE_FOR_EVENT system, triggered_at, sources, details_extracted
|
||||
7. **Event Catalogue Loading** — No YAML config for 150+ event types
|
||||
8. **Detail Factor Detection** — No detail detector (dates, amounts, addresses)
|
||||
9. **Velocity Computation** — No real sliding window / EMA
|
||||
10. **Sentence Pattern Matching** — No regex template matching per IMPLEMENT_GUIDE
|
||||
|
||||
### P2 — Medium (Quality Improvements)
|
||||
11. **Semantic Clusters** — No concept cluster weighting
|
||||
12. **Token Proximity** — No proximity-to-asset scoring
|
||||
13. **Position Weighting** — No primacy/recency bias
|
||||
14. **Cross-Source Confirmation** — No cluster-based NUM_SOURCES
|
||||
15. **Bot Detection** — No echo chamber/coordinated manipulation detection
|
||||

|
||||
|
||||
## What We HAVE Delivered (Positive)
|
||||
|
||||
| Component | Status | Evidence |
|
||||
|-----------|--------|----------|
|
||||
| **Unified Weighted Lexicon** | ✅ Complete | 2,086 terms, -100 to +100, priority span matching |
|
||||
| **Calibration Logic** | ✅ Complete | Lexicon wins on disagreement, amplifies on agreement |
|
||||
| **Centroid Layer** | ✅ Complete | 6 params × 1024-dim from e5-large-v2 |
|
||||
| **Centroid Refinement** | ✅ Working | 30% blend in `ScoringEngine._refine_with_centroids` |

|
||||
| **Unit Tests** | ✅ Passing | 46/46 core NLP tests pass |
|
||||
| **Labeling Pipeline** | ✅ Running | 22 samples processed |
|
||||
|
||||
---
|
||||
|
||||
## Recommendation
|
||||
|
||||
The **core two-layer architecture (lexicon + centroid)** is solid and conforms to the spec's methodological intent. However, the system is **not production-ready** without:
|
||||
|
||||
1. **Real NLP models** (FinBERT, DistilRoBERTa, BERT event classifier)
|
||||
2. **Full event catalogue** (150+ types in YAML)
|
||||
3. **Ingestion service** (RSS/Twitter/Reddit/Exchange/Regulatory)
|
||||
4. **Output sinks** (Hazelcast + ClickHouse)
|
||||
5. **Cross-source intelligence** (NUM_SOURCES clustering, bot detection)
|
||||
6. **Event flag format compliance** (FLAG_TYPE_FOR_EVENT system)
|
||||
|
||||
**Next sprint priority:** Implement P0 items to achieve a minimally viable production pipeline.
