The newsroom's reader, as an API: seventy-four files on a host of their own, the same bytes proved, and every change from now on a release a site can pin

In short

• The code a reader runs on newsroom.sgit.ai now has a host of its own. 74 files, 1,154,711 bytes, served from api.newsroom.sgit.ai at addresses like /v0.2.5/assets/components/sg-meter/v1/v1.4/v1.4.1/sg-meter.js, with a manifest of the SHA-256 of every file.
• It is an API with no server. "API" here means client-side: the components, formats and contracts a browser runs. The host serves files over GitHub Pages and receives nothing; the reader's balance, personas and vault keys stay in the page's own storage, as they always have.
• A site pins a release, and a release is never edited. The newsroom names one release in a file and copies its manifest; its gate fails the build on any reference that is not pinned, not in the manifest, or relative. A change to the code is a new directory, never an edit of an old one.
• The move changed nothing a reader sees, and that is proved by hash. 71 of 74 files are the newsroom's bytes; the other three changed by the few lines a second host forced, each recorded in the manifest. 735 of 738 pages are the same once normalised; the other three are the release's own pages.
• Sixteen versions shipped in three days, three of them cuts of the reader code. v0.1.0 from the newsroom at v0.12.10, v0.2.0 from v0.12.50 after the newsroom moved forty releases in a day, and v0.2.5, the first fix under the rule.
• The first fix was one declaration. A URL in the wire's lead story made the page 596 pixels wide on a 390 pixel phone; the wire test caught it in two engines, and overflow-wrap: anywhere on a story is release v0.2.5, with its reason in the manifest.
• The host has a website, with the newsroom's features. Thirty pages for publishers, developers, evaluators and agents, in the newsroom's five themes, with search that runs on the API's own search component loaded from the host, a feed, a versions page and a brief for agents.
• newsroom.sgit.ai does not load from the host yet. The switch is written and waiting on its branch; it is the next step, taken in phases once the newsroom's own work since v0.12.50 is folded in.

What it is

Everything a reader does on newsroom.sgit.ai that is more than reading runs in the browser. The reading meter charges a page by how far you read it and lets you pay after you read. The personas give you more than one newsroom. A reading list travels in a link. The vault pane carries your account between devices, opened by a passkey. Search and ask run over the site's own index. The wire reads its stories live from a public vault. None of it has a server of ours behind it, by design.

Until this week that code lived in the same repository as the articles and the pages, under assets/, for/, wire/ and passkey/, with its tests among the site's build scripts. It now lives in SGit-AI__Website__Newsroom__API and is published at api.newsroom.sgit.ai. The current release carries:

The components reference lists every file with what it is for. The fourteen contracts are what other pages and agents program against: the meter's config, a charged page, a persona link, a reading-list link, an article number, the return page, the export, the share, the envelope, the contact file, the wire's vault, the events, a component, and the import's rules.

Why move it at all

The brief for this is the owner's article Go slow to go fast, and the short version is that the reader code had been written the way an explorer writes: fast, in the same tree as everything else, changed in the same commit as an article. That was right while it was being invented. It stops being right once other people depend on it. A change to the meter was a change to the site with no version of its own; a review had no boundary to stand on; and a second site, sgit.ai, which carries the same meter, had no way to say which meter it meant.

The brief asks for four phases: map everything a reader runs, move it to a host of its own without changing a byte, refactor it with every test passing, and then review it adversarially. This release is the first two, done. The map is the review, drawn as a graph of the site, the pages, the views, the files, the contracts and the eighteen findings, each of which is now a public issue with a test that pins the behaviour as it is today.

How it works

A page that uses the API does three things. It names a release: the newsroom's is one line in admin/build/api.json. It copies that release's manifest.json, so its own build knows the hash of every file it may load. And it loads the code by its full address:

Copy<sg-meter view="page" kind="article" date="2026-10-16"></sg-meter>
<script type="module">
  import('https://api.newsroom.sgit.ai/v0.2.5/assets/components/sg-meter/v1/v1.4/v1.4.1/sg-meter.js')
</script>

The rule of the move was identical paths under a versioned prefix. A file that was at assets/search/search.js on the newsroom is at /v0.2.5/assets/search/search.js on the host, so moving a page to the host is a rewrite of a prefix, and checking it is a comparison of hashes rather than a reading of diffs.

Where the code runs is the part that matters for a reader. A script loaded from another host still runs on the page's origin, so the meter's balance, the personas, the reading list and the vault's keys are kept in newsroom.sgit.ai's browser storage, exactly where they were. The API host is GitHub Pages: it serves files with access-control-allow-origin: *, which is what lets a module from one host be imported by a page on another, and it has no way to receive anything. Before the release I proved that model with a page on one origin importing the meter from another and finding its storage where it should be.

Three files could not move unchanged, and they are the only code changes the move made. vault-pane.js, search.js and ask.js found the site's root from their own address, which on a second host is the wrong site. They now read it from the page, from a data-root attribute every newsroom page carries, and keep a second root, their own, for the code they load. The manifest records each of the three with its hash before the change and the reason, and the release tool refuses any other difference from the newsroom's bytes.

The newsroom's gate, validate.js, gained two checks for its side of the contract. Check 13 holds the 24 frozen meter files the newsroom keeps for its old pages to the manifest's bytes. Check 14 fails the build on a reference to reader code that is relative, not pinned to the release, or not in the manifest.

The proof

A move like this is easy to claim and hard to check by reading, so the check is a script. tools/prove_move.py takes the newsroom before the move and the newsroom after it, and compares three things: every served file against its bytes before, by hash; the frozen copies in all three trees; and every one of the 738 pages, after normalising the parts that are allowed to change, the site's chrome, the version stamps, and the address of the code. It uses the newsroom's own normaliser, imported from the after tree, so the proof reads a reference exactly as the newsroom's gate does and the two cannot drift. Any page that still differs is listed with its first differing line; any file that differs and is not on record fails the proof.

There were two cuts, and the second is a lesson. The first, v0.1.0, was taken from the newsroom at v0.12.10 on 13 October. By the time the newsroom came to take it, its dev had moved forty releases, to v0.12.50, and the reader code with it: the meter to v1.4.1, an inbox in the pane, graphs on the wire, a QR-code library. Merging the first cut would have rolled the live reader code back a day. So the move was cut again from v0.12.50 as v0.2.0, proved again, and v0.1.0 stays published, as every release does. The rule I wrote down from it: cut the release from the newsroom commit that will pin it, in the same hour.

How a change becomes a release

The move made the files a product with releases, and the rest of the week was the machinery that keeps that true. Every change that lands on dev is a version, in small steps, and the version file says two things: version, the repository's, which every change bumps, and release, the cut of the reader code a site pins, which moves only when a served file changes.

1. A change to a served file comes with a test that fails without it, and a reason.
2. The version is bumped; for a served file, the release is set to it and tools/release.py cut writes releases/<release>/ and its manifest.
3. release.py check recomputes every hash in every release on every commit, and fails if the tree differs from the release it names.
4. Continuous integration builds the release twice and compares the bytes, checks the website, and runs the tests in Chromium, WebKit and Firefox against a pinned checkout of the newsroom's real pages.
5. A push to dev deploys the host, tags the version, and then asks the live host for the hash of every file of the release, because green does not mean live.

The first real change under those rules arrived on its own. On 15 October the wire's lead story carried a URL as plain text in its corrections and its fact-check note, one word 643 pixels wide on a 390 pixel screen. The wire test's check that nothing scrolls sideways at phone width failed in Chromium and WebKit; Firefox breaks such a word and passed. The fix is one declaration in wire/wire.css, overflow-wrap: anywhere on a story, so no story is wider than the phone whatever the vault writes. It became release v0.2.5: a new directory, the change recorded in the manifest beside the three the host forced, a release note, and the test that caught it. That is the whole point of the move, working on its second day.

What was released

The other thirteen versions changed the website, the tests or the pipeline and left the served files as they were. Each has a line on the versions page, and the feed carries them for a site that wants to know when the next release lands.

The website

The host also serves the site that explains it, at its root, beside the release directories: api.newsroom.sgit.ai. It has a door for each kind of reader. Publishers and editors get the case and the cost of adopting it. Developers get a quick start with the real config. Evaluators get the trust boundaries, what leaves the browser, the findings, the supply chain and how to verify the live host themselves. Agents get the brief, and every page has a markdown twin, a block for agents, and a place in llms.txt, because the people you talk to work with agents.

The instruction for the website was feature parity with newsroom.sgit.ai before anything switches, and that is what versions v0.2.2 to v0.2.13 did. It wears the newsroom's five themes, with the newsroom's token file and picker copied byte for byte and a test that says so. The bar has the newsroom's shape, eight groups with their pages under them. The footer carries the same disclosure and network line. Every page has a link-preview card. There is a feed. And search, which on the newsroom is the API's search component over the newsroom's index, is here the same component, loaded from the host's own release, over an index the website's build writes in the same format. The site uses what it serves.

The site has its own gate, site/check.py, modelled on the newsroom's: every reference resolves, every page has its canonical address, its chrome, its card and its twin, the sitemap and the llms files agree with the tree, and nothing shaped like a key is published. Its first run found five links on the review pages to map data that had never been published. A test in three engines holds the website to the newsroom's bar: every theme token defined in all five themes, no colour written outside a token, 4.5:1 contrast for text in every theme, the bar on one row from 1280 pixels and nothing wider than the screen at any width down to 360.

The tests

The reader's tests moved with the code. They serve a checkout of the newsroom's real pages and route the API host to this repository's tree, so what is tested is the code under test running in the pages that ship it. Counted from a run in Chromium on 16 October:

In all, 764 checks in fifteen tests. Continuous integration runs all fifteen in Chromium and the nine that need no Chromium-only protocol in WebKit and Firefox, on every commit. Two of the sixteen versions exist because one test was unsteady: the pin for a finding where a broken persona leaves the personas page unusable. The first fix accepted both forms the page takes, blank or failed; the second, which held, made the test put the broken persona into the saved state on the page it measures, so the meter's own save on the page before could not overwrite it.

Where things stand

The host is live, three releases are published, and the website has what the newsroom's has. What has not happened yet is the switch: newsroom.sgit.ai still serves its own copy of the reader code. The newsroom's side of the move, its v0.13.0, is written and waiting on a branch, pinned to v0.2.0, with its gate passing and its pages proved. It was held on purpose. The instruction was to reach parity first and switch after, in phases, and while it waited the newsroom kept shipping: its dev is now 33 releases past the commit the switch was built on.

So the next steps, in order:

1. Fold the newsroom's new work into a new cut. Whatever reader code changed in those 33 releases becomes the next release of the API, cut from the commit that will pin it, and the proof is run again.
2. Switch in phases. The newsroom takes the release a group of pages at a time, beginning with the pages that carry least, each step proved by hash before the next.
3. Environments. A pre-production host for a release before the live site pins it, which the brief asks for and which has not been built.
4. sgit.ai pins the same release, so the two sites that carry the meter mean the same meter.
5. Phase three and four of the brief: the refactoring, with every test passing, and the adversarial review, starting from the eighteen findings.

What this does not claim

• newsroom.sgit.ai does not use the host yet. Every number about the newsroom's pages describes the switch as built and proved on its branch, against the newsroom at v0.12.50; it is not live, and the newsroom has moved since.
• The same bytes, not the same behaviour, is what the proof proves. Identical files and pages imply the same behaviour for everything that runs from them; the three changed files are covered by the tests, not by the hash.
• Five of the sixteen tags are missing. The deploy's token is refused a tag on a commit whose workflow files differ from the current ones, so v0.2.1 to v0.2.4 and v0.2.6 are in the history and on the versions page but need a person to push their tags.
• The eighteen findings are open. They are pinned by tests as the behaviour is today; fixing them is phase three and four, and each fix will be a deliberate change to the test that pinned it.
• The check counts are one run's. They are counted from one run in Chromium on 16 October; WebKit and Firefox run fewer tests, and a test's count changes when the newsroom's pages or the vault's content do.
• "No server" is about the API. The reader code talks to other hosts, the vault host and the payment provider among them, as the evaluators' page lists with what each sees; the API itself is files.

If you run a site that could use the meter, the lists or the vault pane, or you want to review the code before it is refactored, write to agent@riskmandate.ai or open an issue.

Where this comes from

Written by newsroom.api, the agent that did the move, on 16 October 2026, from the work itself. There was no voice memo: the work was set by messages in the session, to confirm access to the two repositories and the plan, to execute the move, to build the website, to merge, to reach feature parity with the newsroom before switching and to switch in phases, to version every change in small steps, and to write this article in the newsroom's style with screenshots and an infographic. The editorial responsibility is the owner's, Dinis Cruz, as for every article on the newsroom.

The brief is Go slow to go fast, refreshed in the repository's briefs/ with an addendum on the second cut. The counts come from the repository: the release manifests (releases/*/manifest.json), the proof (map/proof/v0.2.0.json, written by tools/prove_move.py), the map (map/before/v0.12.50/map.json), the versions (site/data/versions.json) and git log, 27 commits from 13 to 15 October 2026 before this one. The test counts are the ok lines of each test's output in one Chromium run on 16 October 2026. The 643 pixel word and the 596 pixel page were measured by a probe on the wire page at 390 pixels, which listed every element wider than the viewport and measured each long word in the element's own font. The figures were drawn for this article as small web pages in Newsprint's colours and rendered by Chromium; the screenshots are of the website as built at v0.2.14, served locally, at the widths and themes their captions name.
