+# US Federal Regulations — the CFR, held word for word
+**222,767 regulations** — 219,061 CFR sections and 3,706 appendices — across **all 49 titles
+of the Code of Federal Regulations**, each one as the agency publishes it.
+Statutes say what Congress wrote. The CFR says what the agencies actually require, and for most regulated
+work the regulation is the operative text: an employer's duty under 29 C.F.R. § 1910.1200, a broker's under
+17 C.F.R. § 240.10b-5. This is the other half of federal law, and it is here verbatim — a paraphrase is not
+usable in a filing.

+**All 49 CFR titles are complete.** CFR Title 35 does not appear because it is *Reserved* — the
+eCFR's own title index marks it `reserved: true`, so 49 titles is the whole Code, not a subset.
+Every count in that table was measured by reading the file in `data/` on 2026-09-11. Nothing is estimated and
+nothing is taken from an index page's own total.
+## As of
+The text is the **current** CFR as republished by the U.S. Government Publishing Office from the
+Electronic Code of Federal Regulations, pulled **2026-09-11**. The eCFR title index reported itself
+`up_to_date_as_of 2026-09-09` at pull time. GPO rebuilds a title's bulk file when that title
+changes, so each title carries its own build date — the right-hand column above, and
+`extra.bulk_last_modified` on every row. Titles that agencies rarely touch carry older build dates by
+design: Title 3 (*The President*) was last rebuilt 20-May-2024, and the eCFR title index gives its
+`latest_amended_on` as 2015-03-17.
+This is a snapshot, not a live feed. For a section that has been amended since its title's build date,
+check the eCFR URL in `source`.
+## How complete is it — checked against the live eCFR
+Completeness is not asserted, it is measured. For every one of the 49 titles we asked the eCFR's own
+structure endpoint (`/api/versioner/v1/structure/2026-09-09/title-{n}.json`, an allowed path) for the list of
+section identifiers it currently publishes, and compared it with what is in these files:
+| | count |
+|---|--:|
+| section identifiers the eCFR listed as live on 2026-09-09 | 220,526 |
+| section identifiers held here | 219,055 (99.33%) |
+| listed by eCFR, not held here | 1,520 |
+| held here, no longer listed by eCFR | 49 |
+Of the 1,520 not held, **1,476 carry no text of their own in the source** — they are undesignated
+group headings whose substance lives in their subsections (48 C.F.R. 1.105 *Issuance*, 29 C.F.R. 2530.200a
+*Scope*) or pure cross-reference headings (29 C.F.R. 1917.28). The remaining 44, together with the
+49 we hold that the eCFR no longer lists, are the lag between a title's GPO build date and 2026-09-09.
+No title is a partial pull. Every title is whole as of its build date.
+## The record
+Twelve columns, all strings — the same shape as `docketx/us-statutes`, so the two can be read together:
+`id`, `level` (`federal`), `jurisdiction` (`us`), `code` (e.g. `29 C.F.R.`), `section` (e.g. `1910.1200`),
+`citation` (e.g. `29 C.F.R. § 1910.1200`), `title`, `text` (verbatim), `source` (the eCFR URL for that
+section), `license`, `retrieved_at`, `extra`.
+`extra` is a JSON **string** (parse it with `json.loads`) carrying the place of the section in the Code —
+`cfr_title`, `cfr_title_name`, `chapter`, `chapter_name`, `subchapter`, `part`, `part_name`, `subpart`,
+`subpart_name`, `subject_group`, the eCFR `node` id, the `source_credit` (the Federal Register history note
+printed with the section), and the `bulk_file` / `bulk_last_modified` it came from.
+```python
+from datasets import load_dataset
+ds = load_dataset("docketx/us-regulations")                       # all 49 titles
+osha = ds["train"].filter(lambda r: r["code"] == "29 C.F.R.")     # one title
+```
+## Where it came from, and how
+- **Source:** the official bulk XML at `https://www.govinfo.gov/bulkdata/ECFR/title-{n}/ECFR-title{n}.xml`
+  — GPO's bulk republication of the current eCFR, one file per title, 824,347,237 bytes in total.
+- **robots first.** `https://www.govinfo.gov/robots.txt` places no `Disallow` on `/bulkdata/`, and GPO
+  publishes a bulkdata sitemap for the ECFR collection. Every request identified itself as
+  `DocketRouterBot/1.0 (+https://docketrouter.ai/bot)` and was paced at 1.5s.
+- **What we did not do.** eCFR's own full-text endpoints — `/api/versioner/v1/full/` and
+  `/api/renderer/v1/content/` — are `Disallow`ed in `https://www.ecfr.gov/robots.txt`, so they were not
+  used and no user-agent was switched to get around them. Only `…/api/versioner/v1/titles.json`, which no
+  rule covers, was read, for title names and the as-of date.
+- **Not text:** 7,171 sections and appendices marked `[Reserved]` in the source carry no text and are
+  not included;
+  a further 1,683 entries are heading-only stubs (an undesignated group heading such as 48 C.F.R. 1.105,
+  whose text lives in its subsections) or appendices that exist only as a scanned form image. Nothing was
+  dropped that had extractable text. Tables are rendered as pipe-separated rows; images are not
+  transcribed, and the figure filenames are kept in `extra.graphics`.
+- **Appendices follow the source.** Appendices attached to a *part* or *subpart* are their own records
+  (3,706 of them). Where the source nests an appendix inside a section — as it does with the mandatory
+  Appendices A-F to 29 C.F.R. § 1910.1200 — that text is part of that section's record, which is why the
+  1910.1200 row is 307,615 characters long.
