-# iris
+# iris, now `portal lint`
 
-The iris over a [portal](https://project.uhhm.no/uhhm/portal) site. A
-content push is an incoming wormhole; nothing comes through until it
-checks out.
+The lint lives in [uhhm/portal](https://project.uhhm.no/uhhm/portal)
+since portal 0.6, as the `portal lint` command of the same binary that
+runs a site; its documentation is
+[The lint](https://portal.uhhm.no/lint.html). A content repo's CI
+downloads the release's `portal` and runs `portal lint --path questions`.
 
-```
-iris check --path questions                      # a local checkout
-iris check --repo https://project.uhhm.no/uhhm/questions
-iris --path questions                            # the same, for one-line CI
-```
-
-`check` loads a content repo exactly the way the running site does,
-validates it (every action lands on a page, every transition is one
-the state machine allows, every recorded bucket is read back
-somewhere), and then holds it to the business needs the repo declares
-in `needs.yaml`, when it has one:
-
-- a path of submissions gets each kind of visitor's answer into the
-  bucket it names, within a submission and required-field budget;
-- the handling group holds a desk over that bucket, and every
-  finished state is reachable through the buttons it (and any
-  `also_moved_by` group) offers; no record strands on the way;
-- every stage the business named is a state of the machine.
-
-A need marked `planned` warns instead of failing. Exit status is the
-verdict, so a content repo's CI is one line.
-
-Beyond the verdict, `check` exports what a trainer needs to grade the
-wording: `--needs-tasks` writes the personas as typed choice tasks
-(`--skim` for headings only), `--needs-score` grades an engine's
-answers, and `--needs-sim` writes a resolved model of the whole site.
-`iris replay` runs simulated cases through the site's real aggregate
-engine on a throwaway JetStream and reports every bucket by state;
-`--report-only` takes the same scorecard from a live site's buckets.
-See [portal-trainer](https://project.uhhm.no/uhhm/portal-trainer) for
-what sits around those.
-
-## Matching the site
-
-Every type iris reads is portal's own: portal is a library dependency
-pinned to a release tag in `Cargo.toml`, and iris carries the same
-version number as that tag, so `iris v0.3.39` is the lint for portal
-v0.3.39 and nothing else. A content repo pins `IRIS_RELEASE` to the
-`PORTAL_RELEASE` its site runs. Portal's own release tarball ships the
-matching `iris` binary too, at `/srv/app/<instance>/current/iris`.
-
-## Release
-
-Iris is released by portal's publish job, never by hand: when a
-portal tag is pushed, that job re-pins this crate to the tag, sets
-the version to match, builds and tests it, adds the changelog line,
-and pushes the commit and the tag here. This repo's own CI then
-attaches the binary to the Gitea release as `iris`. A portal change
-to something the lint reads fails the portal release at that step.
-Changes to iris itself land on `main` between releases and ship with
-the next portal tag.
+The `iris` releases up to v0.5.11 stay here and keep working for the
+`IRIS_RELEASE` pins that name them; nothing new is published.
