feat: Phase 1 — extract the client (web SPA + desktop) to dtoro/oikos-web
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.

Utilities for determining whether characters belong to character classes defined by the XML specs.

Organization

It used to be that the library was contained in a single file and you could just import/require/what-have-you the xmlchars module. However, that setup did not work well for people who cared about code optimization. Importing xmlchars meant importing all of the library and because of the way the code was generated there was no way to shake the resulting code tree.

Different modules cover different standards. At the time this documentation was last updated, we had:

  • xmlchars/xml/1.0/ed5 which covers XML 1.0 edition 5.
  • xmlchars/xml/1.0/ed4 which covers XML 1.0 edition 4.
  • xmlchars/xml/1.1/ed2 which covers XML 1.0 edition 2.
  • xmlchars/xmlns/1.0/ed3 which covers XML Namespaces 1.0 edition 3.

Features

The "things" each module contains can be categorized as follows:

  1. "Fragments": these are parts and pieces of regular expressions that correspond to the productions defined in the standard that the module covers. You'd use these to build regular expressions.

  2. Regular expressions that correspond to the productions defined in the standard that the module covers.

  3. Lists: these are arrays of characters that correspond to the productions.

  4. Functions that test code points to verify whether they fit a production.
