Problem: the hexagonal refactor churns the backend tree for nine more phases; the UI delivery stack (web/ SPA, cmd/desktop Wails wrapper, compose/web image) must move to its own repo first so doc/layout rewrites land once on a backend-only tree. Change: - New repo git.hubris.network/dtoro/oikos-web (v0.33.0): web/, desktop/ (updateURL repointed to oikos-web releases), compose/, own CI (web + desktop jobs), own deploy script (CI-green gate, TOCTOU guard, version-tagged images, prune-to-3), own webhook receiver on :9798 + launchd unit, own compose project publishing the same 8091:80. - Cutover executed on mac-mini in order: oikos stack's web service stopped+removed, oikos-web project brought up on 8091; outer Caddy untouched (targets the published port) — serving + Authentik flow + /wails 404 quirk verified post-cutover. - Stripped from oikos: web/, cmd/desktop/, compose/web/, desktop CI workflow, ci.yml web job, Makefile ui/desktop/desktop-package/install targets, the compose web service, oikos-web from deploy.sh's fallback prune list; wails + go-keyring dropped from go.mod, vendor synced. - README / CONTRIBUTING / AGENTS.md / .agents dev+operations docs now point at the new repo; mbse + mascot design docs carry a path note. Risk: production SPA serving depends on the new pipeline now; rollback is versioned-image re-up of the old web service from a pre-split checkout (port 8091). Desktop builds installed before the split still check dtoro/oikos releases — one manual reinstall, noted in the oikos-web release notes. Verification: go vet, make test (race), make generate-check, golangci (no new findings; baseline down 400→365); post-cutover curls — localhost:8091 200, /wails/runtime.js 404, outer Caddy 302 Authentik.

fsevents
Native access to MacOS FSEvents in Node.js
The FSEvents API in MacOS allows applications to register for notifications of changes to a given directory tree. It is a very fast and lightweight alternative to kqueue.
This is a low-level library. For a cross-platform file watching module that uses fsevents, check out Chokidar.
Usage
npm install fsevents
Supports only Node.js v8.16 and higher.
const fsevents = require('fsevents');
// To start observation
const stop = fsevents.watch(__dirname, (path, flags, id) => {
const info = fsevents.getInfo(path, flags);
});
// To end observation
stop();
Important note: The API behaviour is slightly different from typical JS APIs. The
stopfunction must be retrieved and stored somewhere, even if you don't plan to stop the watcher. If you forget it, the garbage collector will eventually kick in, the watcher will be unregistered, and your callbacks won't be called anymore.
The callback passed as the second parameter to .watch get's called whenever the operating system detects a
a change in the file system. It takes three arguments:
fsevents.watch(dirname: string, (path: string, flags: number, id: string) => void): () => Promise<undefined>
path: string- the item in the filesystem that have been changedflags: number- a numeric value describing what the change wasid: string- an unique-id identifying this specific event
Returns closer callback which when called returns a Promise resolving when the watcher process has been shut down.
fsevents.getInfo(path: string, flags: number, id: string): FsEventInfo
The getInfo function takes the path, flags and id arguments and converts those parameters into a structure
that is easier to digest to determine what the change was.
The FsEventsInfo has the following shape:
/**
* @typedef {'created'|'modified'|'deleted'|'moved'|'root-changed'|'cloned'|'unknown'} FsEventsEvent
* @typedef {'file'|'directory'|'symlink'} FsEventsType
*/
{
"event": "created", // {FsEventsEvent}
"path": "file.txt",
"type": "file", // {FsEventsType}
"changes": {
"inode": true, // Had iNode Meta-Information changed
"finder": false, // Had Finder Meta-Data changed
"access": false, // Had access permissions changed
"xattrs": false // Had xAttributes changed
},
"flags": 0x100000000
}

Troubleshooting
- I'm getting
EBADPLATFORMUnsupported platform for fseventserror. - It's fine, nothing is broken. fsevents is macos-only. Other platforms are skipped. If you want to hide this warning, report a bug to NPM bugtracker asking them to hide ebadplatform warnings by default.
