Technical implementation skill for 4_0-ELSIAN-INVEST Module 1. Use when Codex needs to change code, config, tests, or cases in this repo: pipeline implementation, extractor or fetcher debugging, ticker onboarding, expected.json curation, canonical-field expansion, CLI changes, regression fixes, or technical validation. Prefer bounded subagents for disjoint slices, independent verification, and parallel implementation or review. Do not use for governance decisions, backlog prioritization, or independent audit.
docs/project/ROLES.md is the only source of truth for contracts, routing, gates, anti-fraud, and Vision Enforcement.
docs/project/MODULE_1_ENGINEER_CONTEXT.md is the technical manual for this role.
This skill is a thin Codex wrapper for the current Module 1 engineer.
