techstack-correlation

name	techstack-correlation
description	Correlation, confidence scoring, and conflict resolution across all tech-stack signals. Cross-validates and assigns High/Medium/Low confidence per technology.

Tech-Stack Correlation

Scope

The Phase 4 layer that consumes all detection outputs (frontend, backend, infra, security, OSINT) and produces the final vetted technology list:

• Cross-validate signals from independent sources for corroboration
• Score confidence per technology (multi-factor weighted scoring)
• Resolve conflicts between signals (version mismatch, mutually exclusive frameworks, temporal inconsistencies, categorical ambiguity)
• Flag unresolvable conflicts for manual review

Signals (input)

• Raw signals grouped by category: http, dns, tls, javascript, html, repository, job, archive
• Inferred technologies from each detection domain (frontend / backend / infra / security)
• Asset inventory (domains, subdomains, IP map) for URL-context resolution

Inferences (output)

• correlated_technologies[] — each with sources, source_count, agreement_score, corroborating_signals
• conflicts[] — typed (version_mismatch / mutually_exclusive / temporal_inconsistency / categorical_ambiguity), with severity
• technologies_with_confidence[] — confidence level (High / Medium / Low), score (0-1), reasoning breakdown
• confidence_summary — counts, overall score, per-category breakdown, recommendations
• confidence_gaps[] — technologies needing additional evidence with suggested actions

Techniques

See reference/patterns.md.

When to use

• Always — last analysis stage before report generation
• Required to decide what makes the final tech-stack list and at what confidence
• Pure computation; no external requests
