+# ISO 3166-1 alpha-3 country-code table (ledger)
+
+**Topic:** ISO 3166-1 alpha-3 (three-letter) country codes mapped to their
+English short names.
+**Lane:** Extract — data extraction and tables
+**Artifact:** iso3_alpha3.csv (primary), iso3_alpha3.json (machine-readable),
+iso3_alpha3.md (rendered table)
+
+## Source
+
+- Wikipedia — "ISO 3166-1 alpha-3", "Officially assigned code elements"
+  `https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3`
+- Extracted from the live page via `web_extract` (real fetch, no stale cache).
+  → cached raw page:
+  `/root/.hermes/profiles/ledger/cache/web/en.wikipedia.org-8325609c44.md`
+- Parser: `extract_iso3.py`
+- Verification (exit-code verdict): `check_iso3.py`
+
+## Schema
+
+| Column        | Meaning                                        |
+|---------------|------------------------------------------------|
+| `alpha_3`     | ISO 3166-1 alpha-3 code (three uppercase letters) |
+| `country_name`| English short name of the country/territory as listed |
+
+## Provenance & counts
+
+- Officially assigned codes: **249**
+- No duplicate codes; all codes are exactly three uppercase letters
+- Sorted alphabetically by `country_name`
+- Sections intentionally excluded: user-assigned codes (AAA–ZZZ), reserved
+  and deleted codes
+
+## Verification
+
+```
+python3 /root/.hermes/wizard-outputs/ledger/check_iso3.py
+```
+Exit code 0 = correct, 1 = any check failed.
+
+## Notes
+
+- The country names are the title-case English short names used by the ISO
+  3166/MA on the source page.
+- The adjacent `iso3_codes.txt` (plain code-only list) is superseded by this
+  table, which adds the country name for every code.
