EX-NIHILO-CODE-001 — Public Sample Dictionary
Sample grain: one public GitHub repository per row
Sample size: 100 of 339 full-index rows
Order: stars descending
Composition: 97 verified-cut rows; 3 below the 100-merged-PR threshold
Data pull: 2026-09-16

This is a public dictionary excerpt for the  sample, not the complete paid documentation.

Core fields
Field	Meaning
repo_id	Stable GitHub repository identifier
owner	Repository owner or organization
repo_name	Repository name
source_url	Canonical public GitHub URL
language	Named language used for the language-share gate
stars	GitHub star count at pull time
forks	GitHub fork count at pull time
license_spdx	SPDX identifier returned by GitHub
commercial_use_ok	Derived allowlist flag; not a legal opinion or relicense
size_kb	Git disk usage reported by GitHub; not LOC
estimated_loc	Linguist language bytes divided by language-specific bytes per line
primary_language_pct	Named-language bytes divided by total linguist bytes
merged_pr_count	GitHub merged PR count when successfully queried
pr_verified	Whether the PR count was successfully verified
has_tests	Test-directory signal when inspected
has_ci	CI-file or CI-directory signal when inspected
last_commit_date	Repository push date used for recency screening
data_pull_date	UTC date of the index observation
Admission rules
license_spdx is MIT, Apache-2.0, BSD-2-Clause, or BSD-3-Clause
estimated_loc is 100,000–10,000,000
primary_language_pct is at least 0.40
Repository is current, not archived, and not a fork
Verified cut additionally requires merged_pr_count >= 100 and pr_verified=true
Premium cut additionally requires stars >= 1000 and estimated_loc >= 250000
LOC methodology
estimated_loc is calculated from GitHub linguist language bytes:

Rust: bytes ÷ 42
Go: bytes ÷ 38
C++: bytes ÷ 48
Java: bytes ÷ 52
COBOL: bytes ÷ 72
MATLAB: bytes ÷ 44
size_kb is Git disk usage and can include repository history and objects. It must not be multiplied by 30 or represented as source line count. See size_kb_vs_estimated_loc.svg.

Important interpretation notes
A permissive SPDX identifier is an index admission signal, not a relicense or substitute for legal review.
Empty optional fields are allowed; do not advertise “no nulls.”
golang/go uses Gerrit. Its GitHub merged-PR count is not its total contribution volume.
