🏗️ v8.26.0: All-Topic Root Cause Fixes

Overview

Version 8.26.0 implements comprehensive root cause fixes that work for any research topic - from finance to health, climate to technology. The system uses generic intents, configurable authorities, and domain-agnostic triangulation to deliver consistent results across all domains.

Key Root Cause Fixes Applied

Generic Intent System: Universal intents (macro_trends, company_filings, gov_stats) work across all domains
Cached Embeddings Model: Single @lru_cache SentenceTransformer in triangulation/embeddings.py - no reloading
Adaptive Triangulation: Auto-adjusts similarity threshold based on data distribution (70th percentile, bounded 0.32-0.48)
Configurable Authorities: YAML-based primary source detection in config/authorities.yml - add any domain
Domain Fetch Policies: YAML-based HTTP headers/fallbacks in config/fetch_policies.yml - configure any site
Recovery Providers: High-signal providers (worldbank, oecd, imf, eurostat, wikipedia) for automatic recovery
Gate Debug Output: Writes gate_debug.json with metrics, thresholds, and pass/fail decisions

🛡️ v8.26.0: Production-Hardened Features

Generic Intent Classification

Domain-Agnostic Intents: Works for any topic without hardcoded domains
- macro_trends: Trends, outlooks, forecasts across any field
- company_filings: SEC-like documents (10-K, 10-Q, 8-K, annual reports)
- gov_stats: Census, surveys, official statistics
- medical, academic, news, howto: Specialized query types
Intent-Aware Thresholds: Each intent has appropriate quality gates
- Macro Trends: 30% primary, 25% triangulation
- Company Filings: 40% primary, 30% triangulation
- Gov Stats: 35% primary, 25% triangulation
- Medical: 65% primary, 50% triangulation

Enhanced Triangulation System

Cached Model Loading: Single SentenceTransformer instance via @lru_cache - no duplicate models
Adaptive Thresholds: Uses 70th percentile of similarity distribution (bounded 0.32-0.48)
Numeric Token Boost: Cards sharing 2+ years/percentages get similarity boost
Smart Contradiction Filter: Checks units, periods, and relative differences (35% tolerance)

Configurable Domain Policies

1. Authority Detection (`config/authorities.yml`)

50+ Primary Domains: Government, international orgs, central banks, academic
Pattern Matching: Supports wildcards (*.oecd.org, *.gov)
Numeric Requirements: Configurable minimum tokens for primary classification
Easy Extension: Add your industry-specific authorities via YAML

2. Fetch Policies (`config/fetch_policies.yml`)

Per-Domain Headers: Custom User-Agent, Accept, Referer headers
Alternative URLs: Fallback hosts when primary fails (e.g., OECD alt host)
HEAD→GET Fallback: Automatic retry strategy for restrictive servers
Easy Extension: Add new domains without code changes

3. Provider Groups (`providers/groups.py`)

Reusable Groups: macro_econ, encyclopedic, academic, filings
Intent Composition: Combine groups for each intent type
Easy Extension: Add new provider groups for your domain

All-Topic Examples

The v8.26.0 system works seamlessly across all domains:

# Finance/Economics
./run_full_features.sh "GDP growth forecast 2025"
./run_full_features.sh "Apple 10-K filing analysis"

# Health/Medical
./run_full_features.sh "diabetes treatment clinical trials"
./run_full_features.sh "COVID-19 vaccine efficacy studies"

# Climate/Environment  
./run_full_features.sh "renewable energy trends 2024"
./run_full_features.sh "carbon emissions reduction policies"

# Technology
./run_full_features.sh "AI chip market outlook"
./run_full_features.sh "quantum computing breakthroughs 2024"

# Travel/Tourism (still works!)
./run_full_features.sh "global tourism recovery trends"

4. Smarter Contradiction Filtering

35% tolerance for numeric disagreements (was stricter)
Requires 3+ domains before considering contradictions meaningful
Preserves clusters from trusted domains (OECD, UN, etc.)
Only filters when >10% of pairs show contradiction

5. Intent-Aware Query Filtering

Blocks SEC queries for travel/tourism intents
Prevents irrelevant domain searches based on query type
Reduces wasted API calls and improves relevance

Resilient Output Generation Features

1. Always Emit Readable Reports (`WRITE_REPORT_ON_FAIL=true`)

Generates final_report.md with preliminary banner when gates fail
Report includes all sections but warns about lower confidence
Users always get structured insights, never empty-handed

2. Evidence Bundle Persistence (Always On)

Before quality gates run, saves to evidence/ directory:
- final_cards.jsonl - All evidence cards
- sources.csv - Flat source list for easy review
- metrics_snapshot.json - Quality metrics
Ensures work is never lost, even on catastrophic failure

3. Degraded Draft Output (`WRITE_DRAFT_ON_FAIL=true`)

Creates draft_degraded.md with minimal but useful content
Shows metrics snapshot and top 30 evidence bullets
Clear warning about quality gates not being met

4. Dynamic Gate Profiles (`GATES_PROFILE=discovery`)

Two profiles available:

default: Standard strict thresholds (50% primary, 45% triangulation)
discovery: Relaxed for broad topics (30% primary, 30% triangulation)

5. Last-Mile Backfill (`BACKFILL_ON_FAIL=true`)

When gates fail, attempts one more collection pass
Uses free APIs (Wikipedia, DuckDuckGo) with relaxed constraints
Re-checks gates after backfill - can rescue borderline runs

6. Trusted Domain Protection (`TRUSTED_DOMAINS`)

Never filters these domains regardless of credibility:

Default: OECD, UNWTO, WTTC, World Bank, IMF, WHO, UN, etc.
Extend via: TRUSTED_DOMAINS=custom1.org,custom2.com

7. Enhanced Triangulation (`TRI_PARA_THRESHOLD=0.35`)

Lower default threshold (was 0.40) for broader clustering
Numeric token boost: Claims sharing 2+ numbers/years cluster together
Better handles paraphrases in broad topic research

8. Reranker Fallback (Automatic)

Lexical fallback when HuggingFace rate limits (429 errors)
Query-document token overlap scoring
Year/percent bonus scoring for relevance

🎯 Intent-Aware Universal Research (v8.8.0)

Hybrid Intent Classification

The system uses a three-stage hybrid classifier for robust intent detection:

Rule-Based (Stage A): High-precision regex patterns for obvious queries
- Instant detection for clear patterns (e.g., "how to", "near me", "10-K filing")
- Zero latency, deterministic results
Semantic Similarity (Stage B): SentenceTransformer embeddings
- Uses all-MiniLM-L6-v2 model (already loaded for other tasks)
- Compares query to label descriptions and canonical examples
- Works offline, no API dependency
Zero-Shot NLI (Stage C): Optional transformer-based fallback
- Uses facebook/bart-large-mnli for ambiguous queries
- Toggle with INTENT_USE_NLI=true environment variable
- Provides additional accuracy for edge cases

Intent Categories & Routing

Intent	Examples	Primary Providers	Thresholds
Encyclopedia	"origins of platypus", "history of Europe"	Wikipedia, Wikidata	25% triangulation
Product	"best desk fans", "laptop reviews"	Brave, Serper, Tavily	20% triangulation
Local	"beaches in Portland", "cafes near me"	Nominatim, Wikivoyage, OSM	15% triangulation
Academic	"systematic review", "doi:10.1234"	OpenAlex, CrossRef, PubMed	35% triangulation
Stats	"GDP growth 2024", "unemployment data"	World Bank, FRED, OECD	30% triangulation
Travel	"itinerary Japan", "visa requirements"	Wikivoyage, Wikipedia	25% triangulation
News	"latest AI news", "breaking updates"	GDELT, News APIs	30% triangulation
Medical	"symptoms diabetes", "treatment options"	PubMed, EuropePMC	35% triangulation
Regulatory	"Apple 10-K", "SEC filings"	EDGAR, Tavily	30% triangulation
How-to	"how to build", "tutorial"	Brave, Wikipedia	20% triangulation
Generic	Fallback for unclear queries	Wikipedia, general search	25% triangulation

Provider Selection Strategy

Intent-Based Routing: Each intent has tailored provider lists with primary pools
Tiered Fallbacks: Free primary → Paid primary → Free fallback → Paid fallback
Vertical API Exclusion: Prevents NPS, FRED, etc. from generic searches
Site Decorator Filtering: Excludes vertical APIs when site: present
Provider Circuit Breakers: Exponential backoff for 429/403 errors
SerpAPI Circuit Breaker: Query deduplication, call budget (4/run), auto-trip on 429
Rate Limiting: Per-provider RPS controls (Nominatim: 1 RPS, SEC: 0.5 RPS)
Domain Circuit Breakers: Auto-disable failing domains after threshold
Geographic Disambiguation: Handles "Portland OR/ME" ambiguity

🎯 Adaptive Quality System

Supply-Aware Quality Gates

The system adapts thresholds dynamically based on evidence availability and intent:

Intent-Based Triangulation Thresholds

High Confidence (Academic, Medical, Stats): 30-35% triangulation
Medium Confidence (Encyclopedia, News, Travel): 25-30% triangulation
Flexible (Product, Local, How-to): 15-20% triangulation
Supply Adaptation: Further reduced when domains < 6 or cards < 25
Absolute Minimums: 8-10 triangulated cards based on supply

Stats Intent Special Requirements (v8.12.0)

For statistics/economic data queries, stricter requirements apply:

Primary Source Minimum: ≥50% from official statistics domains
Recent Primary: ≥3 primary sources from last 24 months
Triangulated Clusters: ≥1 cluster with 2+ primary domains
Allowed Primary Domains: OECD, IMF, World Bank, BEA, BLS, IRS, CBO, GAO, Eurostat, UN, NBER, Nature, Science
Banned Representatives: Advocacy sites (taxfoundation.org, americanprogress.org, etc.) flagged as non-representative
Cluster Quality: Each cluster must have ≥2 distinct primary domains to count as triangulated
Extraction-Only Facts: All Key Findings/Numbers must be directly extracted and entailed by evidence

Primary Source Requirements

Standard: 40% of evidence from primary sources
Limited Supply: 30% when primary/credible ratio < 0.5
Whitelisted Domains: OECD, IMF, World Bank, central banks preserved as singletons

Domain Balance

Default Cap: 25% max from any single domain family
Family Grouping: Related domains grouped (all .gov, all .edu)
Triangulation Priority: Triangulated cards preserved during capping
Few Domains: 40% cap when < 6 unique domains
Post-Filter Rebalancing: Reapplies caps after credibility filtering
Generic Diversity: Class-based injection (site:.gov, site:.edu) not specific domains
Smart Relaxation: Prevents over-trimming quality sources

Last-Mile Backfill

Triggers when within 5pp of triangulation target
Requires > 20% time budget remaining
Activates after 2+ regular backfill attempts

Adaptive Report Generation

Reports automatically scale based on evidence quality:

Tier	Word Count	Token Budget	Triggers
Brief	600-900	~1,200	Rapid depth, low supply, confidence < 0.55
Standard	1,100-1,600	~2,200	Normal evidence, moderate confidence
Deep	1,800-2,800	~3,800	Rich evidence, confidence ≥ 0.75, 20+ triangulated

Confidence Calculation

confidence = 0.4*triangulation + 0.3*primary_share + 0.2*domain_diversity + 0.1*(1-error_rate)

Report Features

Confidence Badge: 🟢 High | 🟡 Moderate | 🔴 Low (null-safe)
Supply Context: Transparent reporting of evidence constraints
Adaptive Sections: Token budgets adjust per tier
Quality Signals: Clear explanations of any threshold adjustments
Insufficient Evidence Reports: Enhanced with metrics table, actionable recommendations

🔒 v8.15.0 Enhanced Reporting System

Hard Quality Gates

The system now enforces strict quality gates that prevent low-quality reports:

Final Report Generation: Only when ALL gates pass:
- Triangulation ≥ 50% (configurable)
- Primary share ≥ 33% (configurable)
- Evidence cards ≥ 25 (configurable)
Single Source of Truth: Metrics loaded from disk (metrics.json) to prevent drift
No Partial Reports: If gates fail, only insufficient evidence report is generated

Citation-Bound Key Numbers

Every numeric claim must have verifiable citations:

Support Requirements: Numbers included only if:
- Supported by ≥2 distinct domains, OR
- Supported by ≥1 source from PRIMARY_WHITELIST
Citation Binding: Each key number displays inline citations [1] [2] [3]
Citation Safety Section: Reports citation coverage with PASS ✅ or NEEDS ATTENTION ⚠️

Sentence-Aware Content Trimming

Professional outputs without dangling ellipses:

Smart Boundaries: Ends at sentence boundaries when possible
Abbreviation Handling: Recognizes common abbreviations (Dr., Inc., etc.)
Word Boundaries: Falls back to word boundaries if no sentence end found
Clean Ellipses: Only adds "…" when truly truncated mid-thought

Actionable Insufficient Evidence Reports

When gates fail, provides concrete next steps:

Intent-Specific Guidance:
- Stats: Query OECD/World Bank SDMX endpoints
- Medical: Search PubMed systematic reviews
- Regulatory: Check official .gov sources
Troubleshooting Tips: Diagnoses low triangulation, primary share issues
Backfill Strategy: Clear steps to improve evidence quality
Acceptance Thresholds: Explicit criteria for report generation

Source Strategy Transparency

Documents actual provider usage and backfill policy:

Providers Used: Lists actual providers from the run
Primary Source Criteria: Shows whitelisted domains by category
Backfill Policy: Explains whether backfill was needed and why
Search Approach: Documents intent-based strategy and filters applied

Report Section Parity

All reports include consistent sections:

Executive Summary (sentence-trimmed findings)
Key Findings (triangulated, multi-domain)
Key Numbers (with citations)
Evidence Supply (metrics from disk)
Citation Safety (validation status)
Source Distribution (domain breakdown with 🔷 markers)
Appendix (links to supporting documents)

Intent-Specific Settings: Stats intent has specialized provider preferences and thresholds
Domain Tiers: TIER1 (1.00) to TIER4 (0.20) credibility weights

Atomic Writes & Transaction Support

Run Transaction: Wraps entire pipeline with research_system.utils.file_ops.run_transaction()
Crash Cleanup: Deletes partial reports on unhandled exceptions
RUN_STATE.json: Tracks execution status (RUNNING → COMPLETED/ABORTED)
Temp + Rename: All file writes use atomic operations preventing partial outputs

Unified Metrics System

Single Computation: research_system.quality.metrics_v2.compute_metrics() called once
FinalMetrics Dataclass: Consistent object used across all reports and headers
Hard-Gate Enforcement: gates_pass() prevents final report when quality insufficient
Metrics Synchronization: Headers, body text, and metrics.json use same values

Evidence Canonicalization

DOI Deduplication: research_system.evidence.canonicalize.canonical_id() prevents duplicates
Mirror Collapse: sgp.fas.org → congress.gov, everycrsreport.com → congress.gov
CRS Report Numbers: Extracts R12345, RL1234, RS1234 patterns for canonical grouping
Inflation Prevention: Metrics count unique canonical sources, not mirrors

Domain Tier Scholarly Weighting

TIER1 (1.00): Official statistics (.gov, international orgs), peer-reviewed journals
TIER2 (0.75): CRS/CBO/GAO reports, NBER working papers, national statistics
TIER3 (0.40): Think tanks (Brookings, Urban, Tax Foundation), OWID (if DOI-bound)
TIER4 (0.20): Media, encyclopedias, blogs
Primary Marking: Only TIER1 + peer-reviewed marked as is_primary=True

Stats-Intent Specialized Pipeline

Phase 1: Official providers (OECD, IMF, World Bank, Eurostat)
Phase 2: Data fallback (Treasury, IRS, Census, CBO, CRS, BLS, BEA)
Phase 3: General providers demoted to context-only (not counted in metrics)
Admissibility: Requires numeric content, excludes partisan sources
Jurisdiction Filtering: Excludes mismatched geographic sources

Evidence-Number Binding Enforcement

Mandatory Binding: Every numeric bullet must bind to specific evidence card
Quote Span Required: Each binding includes exact quote supporting the number
Placeholder Rejection: [increasing], [TBD] values cause binding failure
Report Blocking: No final report generated if bindings incomplete

Enhanced Quote Rescue

Numeric Density: ≥3% tokens must be numerals for stats quotes
Primary Only: Only quotes from is_primary=True sources admitted
Pattern Detection: Uses regex to identify percentages, rates, counts
Quality Floor: Non-numeric quotes require explicit claim_like_high_conf flag

Credibility-Weighted Representative Selection

Medoid Algorithm: Selects cluster representative by minimizing weighted distances
Topic Similarity Floor: 50% similarity to original query required
Domain Trust Weighting: TIER1 sources prioritized over think tanks/media
Prevents Bias: No more partisan talking points as cluster representatives

Partisan Content & Jurisdiction Filtering

Partisan Exclusion: Heritage Foundation, Center for American Progress, JEC partisan pages
Geographic Matching: UK sources excluded from US tax queries
International Org Exception: OECD/IMF/UN always allowed regardless of jurisdiction
Stats Intent Strictness: Partisan filtering enforced for statistical queries

Robust Academic Search

OpenAlex Primary: Uses proper search= parameter instead of filter=title.search:

🆕 v8.11.0 Comprehensive Quality Improvements

1. Quality Gate Logic Fix

Never emit Final Report when gates fail: Fixed critical logic flaw where both insufficient evidence report AND final report were generated
Single source of truth: When quality gates fail (primary_share < 40% or triangulation < 25%), ONLY insufficient evidence report is created
Early return logic: Prevents downstream report generation when evidence quality is insufficient

2. Safe Datetime Formatting

New utility module: utils/datetime_safe.py handles all datetime formatting robustly
Handles all input types: float (epoch), datetime objects, None, strings
No more crashes: Prevents 'float' object has no attribute 'strftime' errors
Duration formatting: Human-readable duration strings (e.g., "5m 23s", "1h 15m")

3. Strict Claim Schema & Validation

New claim schema: reporting/claim_schema.py enforces structured claim validation
Required fields for numbers: Must have value, unit, geography, time period, and definition
Source classification: Official stats, peer review, gov memo, think tank, media, blog
Partisan detection: Automatically tags claims by source alignment
Confidence scoring: Claims scored by triangulation, source quality, and credibility

4. Enhanced Key Numbers Extraction

Context required: Numbers must have units, time period, and geographic context
Triangulation required: Only numbers from 2+ independent sources
Proper formatting: "25.1% — effective federal tax rate (US, 2023) [2 sources]"
No placeholders: Returns empty list if no valid numbers found (allows template guards)

5. Template Guards for Report Sections

No empty sections: Sections only rendered if they have valid content
No placeholder text: Removes "N/A", "No robust numbers", etc.
Conditional rendering: Key Numbers section skipped entirely if no valid numbers
Meaningful fallbacks: "No publishable findings met evidence thresholds" when appropriate

6. Source-Aware Clustering

Prevents mixing: Statistical sources not mixed with advocacy/opinion sources
Claim type classification: numeric_measure, mechanism_or_theory, opinion_advocacy, news_context
Source compatibility: Official stats don't cluster with think tanks for numeric claims
Stricter thresholds: 0.62 similarity for numeric claims (vs 0.40 for others)
Quality scoring: Clusters ranked by domain diversity, source quality, triangulation

7. Comprehensive Test Suite

10 focused tests: Cover all critical paths and edge cases
Quality gate test: Verifies no final report when metrics fail
Datetime safety test: Tests all input types and edge cases
Claim validation test: Ensures only valid claims pass filters
Template guard test: Verifies no empty/placeholder sections
