+# Changelog
+
+One line per change, grouped by the release that shipped it. Newest
+first. A release is a Cargo.toml bump plus a `v<version>` tag; the
+content repos pin the tag they run (see the end of this file).
+
+## 0.3.43 (2026-09-23)
+
+- Mail is content: `mail: { to, subject, body }` on a state in aggregates.yaml sends when a record enters that state (`to: submitter` or one address; `{field}`, `{site}`, `{chain}`, `{email}` in the templates), and an invite mails its one-time link built in; `site.yaml` gains `mail: { from, reply_to, invite }`. Portal renders and publishes on `portal.mail.send` in the `WORMHOLE` stream; uhhm/gdo delivers. The lint requires a required `email` field on every form recording into a bucket that mails the submitter.
+
+## 0.3.42 (2026-09-23)
+
+- people: the Kanidm person lookup reads the body, since Kanidm 1.11 answers a missing person with 200 and `null` rather than 404; before this every invite skipped account creation and failed on the group step
+
+## 0.3.41 (2026-09-23)
+
+- publish: the iris release step retries on a fresh clone when its push loses a race against a push to iris main (the v0.3.40 tag never published)
+- iris: `check --access` prints the access matrix, and every check validates the compiled policy against the schema
+
+## 0.3.40 (2026-09-23)
+
+- One access policy, compiled from content into Cedar on every load (`src/access.rs`): pages, resource reads, desk transitions, self transitions and the automation endpoint all decide through it; decisions carry rule ids, refusals and mutations publish on `portal.access.decided`, and `portal.access.<site>.may` answers the same question for other apps over NATS
+- `invite: {group}` on an alternative onboards a person into Kanidm from a desk (`src/people.rs`, `KANIDM_API_TOKEN`), recording the one-time credential link in `portal_invites` and on `portal.people.invited`
+
+## 0.3.39 (2026-09-23)
+
+- publish: releases the matching uhhm/iris by proxy - re-pins, builds, tests and tags it as this version (needs the `IRIS_PUSH_USER` variable and `IRIS_PUSH_TOKEN` secret); iris carries portal's version number from here on
+
+## 0.3.38 (2026-09-22)
+
+- publish: the iris build step gets a writable cargo home; the v0.3.37 tag never published
+
+## 0.3.37 (2026-09-22)
+
+- The lint moves to its own repo, uhhm/iris: `question_lint` becomes `iris check`, `needs_replay` becomes `iris replay`; the tarball ships `iris` (pinned in publish.yml) instead of `question_lint`; the needs module and local loaders leave portal
+
+## 0.3.36 (2026-09-22)
+
+- Question nav: a followup is offered only once earned - the verified chain answered the alternative leading there, or a link that records nothing leads on from an earned page. Standing on a page no longer unlocks the pages behind its forms; the chain index now records which alternative was answered
+- One bounded HTTP client for every server-side fetch: 20 s budget, size caps per kind of fetch (`src/http.rs`)
+- Uploads are refused past 20 MB while streaming, and the route body limit that had capped them at axum's 2 MB default is raised to match
+- `tests/jetstream.rs`: the store, the event log and the projection tested against a real JetStream (CI starts a throwaway one)
+- `content` split into `gitea`, `validate`, `markdown`, `handlers`; every path still `content::x`
+- This changelog, and the table of what each site runs
+- Business needs as a checkable spec: needs.yaml + question_lint pass
+- needs: `success` states and a resolved simulation model
+- needs: `stages` - every stage the business named must be a state
+- needs_replay: make simulated cases real aggregates, report buckets by state
+- needs: also_moved_by - a need carried by more than one group's desk
+

+- Inline encouragements with the submit button, vertically centered

+- Update style/main.css
+- YES canvas: size off its own container rect, not window.innerHeight

+- Validate action targets; format timestamps client-side; clippy cleanup
+- Question nav + gateway alternatives

+- Feature icons: masked span painted by currentColor, not <img>
+- Responsible note: one line, same hue and size as the hero description
+- Responsible note as <small>: meta information, dimmer than the description
+- Responsible note back to the footer, above the question nav
+- Bound inputs: a field that loads its value from a sibling-parameterized resource
+- add some more width to our alternatives
+- Accent to a dusty press-cyan, a muted echo of the canvas's cyan ink
+- Editor type in rem: prosekit's px typography ignored the responsive root
+- Ban px from stylesheets: every length rem/em off the responsive root
+- No translucent input chrome: solid ink-dim placeholders and embed meta
