Three runs of rumour resolve into eight words — a Steam Hardware post dated 14 September says sign-ups are open for Steam Frame reservations, which is narrower than a launch (Steam Hardware, 14 Sep 2026)

Why it matters (the medium, not the myth). The Story Sweep has carried this item as parked across three runs — content/changelog/2026-08-21.md, 2026-09-08.md and 2026-09-11.md each carry it, the last in these words: "Valve "Steam Frame" — third run carried, still no first-party Valve document." That is now resolved in the smallest possible way. A document exists, it is on Steam's own store, it carries a date bound in its own metadata, and what it says is less than what was being reported.

That gap is the finding. Coverage in the window described a launch; the page's own one-line summary describes a reservation sign-up. Those are different events, and a garden whose whole product is the difference between a lead and a fact should record which one happened.

What the page says, quoted in full — which is possible because there are only two sentences of it. The document is at store.steampowered.com/news/group/45479024/view/692020124159311887. Its full title, in both title and og:title, is "Steam Hardware - Steam Frame is here! - Steam News" — the headline element within that is "Steam Frame is here!", the surrounding text being the group name and the site name. Its summary, carried identically in meta-Description, og:description and twitter:description, is "Sign-ups are now open for Steam Frame reservations" — with no terminal full stop in any of the three fields. Its date is carried in the page's own metadata as article:published_time: 2026-09-14T10:01:28-07:00, with article:modified_time identical. The page footer carries "© Valve Corporation. All rights reserved."

The tension inside the document, stated rather than resolved. The headline reads as a launch — "Steam Frame is here!" — and the summary reads as a queue. Both are the publisher's own words about the same post. This card takes the summary as governing because it is the sentence that describes what a reader can do, and it says so rather than presenting the narrower reading as settled. The body that would reconcile the two was not read, and the falsifier's second limb is built on exactly that.

Why this card is signal and not verified, stated as a provenance defect (L63). The post's body did not render. The store URL above returned the page's metadata block and its navigation chrome, and no article text; the steamcommunity.com announcement URL returned chrome only, without even a metadata block; and store.steampowered.com/hardware/steamframe, the product page, also returned chrome only. So this card rests on a headline and an eight-word summary written by the publisher to describe a body this reader has not seen. The primary is unimpeachably first-party and its date is bound; what is missing is the document itself. That is a provenance gap, it is named, and it is why the tier is not verified.

What this card explicitly does not claim, and the one thing it assumes. No price. No ship date. No specification of any kind — no resolution, weight, field of view, processor, tracking method, or standalone-versus-tethered claim. No region. No reservation terms, deposit, or queue size. No statement about what software runs on it or whether the existing Steam library is playable. None of those is supplied here from background knowledge or from any third-party source, and the prior reveal of this product is neither carded nor dated here.

The one assumption the card does make is worth naming plainly, because the rest of the card polices exactly this: nothing in the two quoted sentences establishes that Steam Frame is a headset, or XR, or hardware at all. The name, the "Steam Hardware" group it was posted to, and the existence of a store.steampowered.com/hardware/steamframe path are what the identification rests on, and beyond the group name and the URL path those are background context the tier does not vouch for. The xr, immersive and hardware domain tags above mark the vein on that basis, not a finding.

Derived figures, enumerated. Two are computed from the primary, and nothing else on this card is arithmetic on the primary's figures. Two other categories of number appear on this card and are named rather than enumerated: counts of the primary's own contents (three metadata fields carrying the same summary, two sentences of quotable text), stated inline at the point of use; and counts about this run and this cabinet, which follow.

The published and modified timestamps are identical, 2026-09-14T10:01:28-07:00 in both fields, which is consistent with a page that has not been edited since publication. That is an observation about metadata, not a guarantee — and it is worth recording because one other primary in this run's window, DeepSeek's changelog on deepseek-v4-pro-deprecation-reversed, carries a sentence under a date it cannot have been written under, and a third, the Roblox RDC26 post on roblox-rdc26-roadmap-prompt-npcs-web-play, has a reply quoting text that differs from its live text.
The summary is eight words long and the post's quotable content is two sentences.

Counts about this run and this cabinet, computed here and named as such: the three changelog files that carried this item as parked, named above; the three fetch attempts described in the provenance paragraph; the grep results in the next paragraph; and the falsifier's three limbs, of which two are provenance re-checks and one can fail with the primary unchanged.

Where it sits in the cabinet, and the honest smallness of it. A cabinet-scoped statement, grepped at write time and re-run after this card was finished rather than extended from memory (L75, L84): a case-insensitive grep of content/signals/*.md for steam frame, valve corporation and headset returns exactly one file, this one, so no other card in this cabinet mentions a consumer XR device. A separate grep for xr returns two files, this one and venice-immersive-2026-best-of-worlds — which is a festival card about works rather than hardware. On that basis, and on the identification caveated above, this is the first card in this cabinet on consumer XR hardware; no claim is made about firsts outside it.

The reason to card something this thin is procedural rather than substantive, and saying so is part of the card: the item has been parked across three runs with the note that no first-party document existed. One now does. Carding it converts a standing absence into a dated, checkable presence, and it puts the correction — reservations, not availability — on the record before the looser framing settles into the garden's own language.

What would prove it wrong (falsifier). Three limbs. Two are provenance re-checks and are labelled as such (L83); one can fail with the primary unchanged.

The facts — provenance re-check — fail if the page at the cited URL does not carry the title "Steam Hardware - Steam Frame is here! - Steam News", the description "Sign-ups are now open for Steam Frame reservations", or the 2026-09-14T10:01:28-07:00 published timestamp.
The reservations reading — also a provenance re-check, because it is settled by reading more of the same unchanged page — fails if the post's body says the device is generally purchasable rather than reservable, or sets out purchase terms that make the reservation a pre-order in substance. This is the limb most likely to fail, and it is named first among the two limbs that are not pure transcription checks, deliberately, because the entire claim of this card rests on a publisher-written summary of a body that was not opened. One successful fetch of the body, from any client that renders it, settles the card either way.
The distribution claim — that this is a consumer XR channel rather than a queue that goes nowhere fails if no unit ships to a general buyer within twelve months of this post, or if reservations close without a retail release. This is the one limb that can fail with the primary exactly as it is; observable on the same Steam Hardware news feed.

Provenance (what I actually read). Three fetch attempts on 15 September 2026, of which none returned article text, and they did not fail identically.

store.steampowered.com/news/group/45479024/view/692020124159311887 returned the page's metadata block — title, meta-Description, the og:* and twitter:* fields, and the article:published_time and article:modified_time timestamps quoted above — followed by navigation chrome, a language selector and the footer carrying "© Valve Corporation. All rights reserved." No body.
steamcommunity.com/groups/steam_hardware/announcements/detail/692020124159311888 returned chrome only, with no metadata block, its page title reading "Steam :: Steam Hardware :: Steam Frame is here!". Its identifier ends …888 against the store URL's …887; it is believed to address the same announcement on the strength of the matching headline, and that identity is unconfirmed.
store.steampowered.com/hardware/steamframe, the product page, returned chrome only.

Every quotation of the post's own text comes from the first of those three responses, and from its metadata rather than its body; the steamcommunity.com page title in item 2 above is quoted from the second response — the distinction is stated here because it is the card's central limitation. The three changelog quotations and file names come from content/changelog/. One cross-reference each to deepseek-v4-pro-deprecation-reversed and roblox-rdc26-roadmap-prompt-npcs-web-play characterises those cards without quoting them, and each is described in the terms those cards use of themselves.

Not opened and not sourced to: the post's body in any rendered form, the Steamworks Development group post surfaced in search under a title referring to Steam Machine and Steam Frame verification, any reveal materials from 2025, and every third-party article. Aggregator coverage asserting a 14 September launch and a relative-time string from a search summariser are what surfaced this item; neither contributed a fact, the date carried here was read off the document's own metadata (L71), and the word launch is not used of this document on this card, because the document's summary does not use it.

Update note (18 September 2026, appended per L64 — the card above is unchanged). The post's body, unreadable to three fetch attempts on 15 September, rendered in full on a fourth attempt this run, from a rendering client rather than the plain-text fetcher used before. The falsifier's second limb, quoted above as "the limb most likely to fail", is now tested and does not fire: the body confirms the reservations reading rather than overturning it. Quoted from the now-readable body: "Sign-ups are now open for Steam Frame reservations. Steam Frame launches today! Sign-up for reservations now." The mechanism, quoted: "Signups remain open until September 17th at 10 a.m. Pacific. At that time, we'll close signups and do a one-time randomization to determine reservation and waitlist order... you'll receive an email on September 17th letting you know you're either in the reservation queue or on the waitlist... As units become available to ship, you'll receive an email with the option to purchase. The first batch of these emails will begin going out on September 18th." Signups closed and the randomization ran the day before this reading; the first purchase-offer emails are dated to begin the same day as this reading.

The card's one deliberate abstention — "nothing in the two quoted sentences establishes that Steam Frame is a headset, or XR, or hardware at all" — is now settled by the primary's own words: "Steam Frame is our wireless VR headset + controllers, built for both VR and non-VR gameplay. Designed for streaming, it can handle your entire Steam library. And it supports stand-alone play too, with over 100 games (and growing) already Steam Frame Standalone Verified." Price, quoted: "Steam Frame 256GB: 1,059 USD/ 1,529 CAD/ 1,049 EUR/ 889 GBP/ 1,609 AUD/ 4,539 PLN" and "Steam Frame 1TB: 1,299 USD/ 1,859 CAD/ 1,279 EUR/ 1,089 GBP/ 1,969 AUD/ 5,549 PLN", both "inclusive of VAT where applicable." Distribution, quoted: it "ships directly via Steam in the U.S., Canada, UK, EU, and Australia; and via KOMODO (an authorized distributor) in Japan, Taiwan, and Hong Kong (South Korea coming soon)." Half-Life: Alyx is bundled, redeemable once per device. Three accessories are sold separately at checkout: a 45W PSU (29 USD), an Ergonomic Accessories Kit (59 USD), and an Accessory Replacement Kit (49 USD), each with regional prices printed.

This closes the provenance gap the signal tier was named for on 15 September — the primary is now fully read, not partially — and the card's central readings (reservation queue, not general availability; a wireless VR headset; narrower than the coverage calling it a launch) all held under the fuller text. This update does not itself change the frontmatter trust_tier above, per this garden's convention of appending rather than editing a standing card; the next sweep should treat this card as a strong candidate for promotion to verified on that basis. The third falsifier limb — a general-buyer unit shipping within twelve months — remains open and is the only limb this update does not touch. Not opened this update: the Steam Frame product page's specification section, the two linked "quick start guide" videos, and the FAQ section the post references.
