Where the Revolutionary FAR Overhaul (RFO) stands — official rulemaking status by FAR part (final / proposed / legacy) and verified agency adoption, in one scannable view. Built by former Contracting Officers; grounded in official sources.
The RFO, directed by Executive Order 14275 ("Restoring Common Sense to Federal Procurement"), is rolling out on two tracks. First, agencies issued class deviations on the commercial-buying path (FAR Parts 12, 13, 19) ahead of formal rulemaking. Second, the FAR Council has now opened formal notice-and-comment rulemaking — the first batch of proposed rules published June 23, 2026, with comments due July 23, 2026.
Read this in two layers. The first table is the government's official rulemaking status (what the Federal Register and acquisition.gov say). The second is ArcClause coverage — what A-Frame's clause engine has independently encoded and verified. The two are not the same thing: ArcClause coverage is our data, not the regulation's status, and is necessarily narrower than the full overhaul.
Source: Federal Register (June 23, 2026) and acquisition.gov/far-overhaul. The FAR Council has stated it intends to issue a total of 12 proposed rules that will collectively revise the entire FAR; the batch below is the first four (covering ~20 parts). Parts not listed below are not yet in a published proposed rule and remain legacy FAR unless an agency has issued a class deviation (see Layer 2).

FAR Case 2026-005 covers Parts 5, 24, 29 (and conforming Part 52 changes). We confirmed the four published rules and the July 23, 2026 deadline against the Federal Register and an industry summary; we did not independently re-read the full text of every rule, so treat the per-part groupings as the published case scope, not a clause-level mapping. Final rules had not been issued for any RFO part as of this stamp. Verify the live list at acquisition.gov/far-overhaul.
This is A-Frame's own data, not the government's status. ArcClause is a deterministic clause-selection engine that resolves a "regime" (legacy vs. RFO deviation) per FAR part, per agency, per solicitation date.
ArcClause has encoded and CO-verified RFO deviation clause text for the commercial path — FAR Parts 12, 13, and 19 (plus one Part 22 clause). For every other part it carries the legacy FAR text and, where an agency is on RFO for a part it hasn't yet encoded, the engine resolves to legacy and raises a review flag rather than asserting a clause is correct. That is a deliberate integrity choice, not full RFO coverage.
ArcClause tracks adoption only for agencies whose posture it has researched ("verified agencies"). An agency not on this list triggers an unverified-posture banner instead of a possibly-wrong legacy assumption. The table below reflects exactly what is encoded in ArcClause's adoption data as of June 14, 2026 (the data file's own as-of date) for the three commercial-path parts.

Source: ArcClause agency-adoptions.json (as-of 2026-06-14). Dates are the agency class-deviation effective dates for new solicitations, drawn from agency memos posted to acquisition.gov; several were extracted from the deviation PDFs and the data notes flag them to verify against the exact effective language before relying on edge dates. The DoD dates (RFO Phase 1, eff. 2026-02-01) are corroborated across industry summaries; the data notes that the primary OSD memo was not machine-fetchable when recorded, so re-confirm at the source.
*HHS Part 12 shows legacy because the HHS class deviation on file did not cover Part 12; an HHSAR deviation implies alignment but ArcClause has not recorded a Part-12 RFO date for HHS.
Agencies not listed (e.g., DHS, DOI, DOJ, State, DOT, Education, EPA, HUD, Energy, Labor) have deviations whose effective dates ArcClause could not reliably confirm; the engine shows an unverified-posture banner for them rather than guessing. Absence here is not evidence an agency has not adopted RFO.
How ArcClause uses this. For a given solicitation, the engine takes your agency, FAR part, and solicitation date, finds the latest adoption record effective on or before that date, and selects the matching clause regime — defaulting to legacy with a review flag when it can't verify RFO. Same inputs always yield the same output; AI never picks clauses.
If you contract for one of the verified agencies above and your solicitation is dated after that agency's adoption date for Parts 12, 13, or 19, you are likely on the RFO deviation regime for that part — different provisions and clauses than legacy FAR. For the parts now in proposed rulemaking (1, 2, 3, 4, 5, 6, 7, 10, 18, 24, 26, 29, 33, 37, 39, 40, 41, 49, 53), nothing is final yet; legacy FAR still governs unless your agency has a separate deviation. When in doubt, the cognizant Contracting Officer determines what applies.

ArcClause picks the legacy or RFO-deviation provisions and clauses for your solicitation — by agency, part, and date — with the prescription behind every row. Free, no login.
