Methodology
How this record is built
Every figure Luminory publishes is either read directly from the U.S. Federal Register API or derived from it. This page says which is which, because a number whose derivation is unstated is an assertion rather than a measurement.
1. Source
The Federal Register API, federalregister.gov/api/v1/documents.json. Public, free, no key. Documents of type=RULE only: final rules that carry an effective date. Proposed rules, notices and presidential documents are excluded, because none of them binds.
Federal Register content is a work of the United States Government and is in the public domain.
2. The query
Rules whose effective_on falls between the record date and 400 days after it. The current window is 19 October 2026 to 23 November 2027, and the API reported 227 matching documents when it was read.
3. Fields read directly from the source
| Field | Source key | Coverage |
|---|---|---|
| Effective date | effective_on | 227 of 227 |
| Promulgating agency | agencies[] | 227 of 227 |
| CFR reference | cfr_references[] | 227 of 227 |
| RIN | regulation_id_numbers[] | 187 of 227 |
| Docket ID | docket_ids[] | where present |
| Source document | html_url | 227 of 227 |
4. ⚠️ What is derived, and therefore weaker
Figures computed here rather than reported by the source are marked as derived. The following are computed by Luminory rather than reported by the source.
- Days until binding. The effective date minus the record date. Arithmetic, but it goes stale: it is correct as of 19 October 2026 and is not recalculated when you load the page.
- Sector. Mapped from the promulgating agency's name against a pattern list. ⛔ Where no mapping is certain the record is left unclassified rather than guessed: 19 of 227 records are unclassified today. A wrong sector on a legal record is a silent error, and silence is where rigidity belongs.
- Prior state. Detected by pattern match on the source abstract, and present for 146 of 227 records. ⛔ Luminory never writes a prior state the source did not state. Where the document is silent, the record says not stated in the source document.
5. What does not ship
A record with no source URL is dropped rather than published. 0 were dropped from the current pull.
Per-rule pages are earned, not automatic. A rule earns its own page only when there is enough sourced material to say something a calendar row does not already say; otherwise it appears as a calendar row and links to its Federal Register document. This is deliberate: a fan-out of thin near-duplicate pages is the shape that demotes a domain, and it would not serve a reader either.
6. Refresh and staleness
The record was generated 2026-10-19. Rules are added to the Federal Register daily, and effective dates are themselves amended by later rules, so the window moves. Every figure on this site carries the date it was read. Nothing here is re-checked at page load.
7. ⛔ What this record is not
Not legal advice, and not a determination of coverage. Luminory records what binds and when. It does not state whether a rule applies to any person or organisation, and it does not interpret obligations. For applicability, read the rule and take advice.
