What

Adds the two user-visible behaviours from layer5io/meshery-cloud#6002 that the User Invitations page does not yet carry: how the open signup invitation is applied at sign-in, and what an administrator now sees when an invitation edit is refused.

One file, additive prose only, no restructuring:
content/en/cloud/concepts/identity-and-security/users/user-invitations/index.md

Relationship to #1215

#1215 is already open against this same page for the same upstream change, covering the Manage Invitations permission on the open signup marker (both directions) and the precedence of the Edit Organization picker over isDefault. This PR deliberately does not repeat those facts and touches no line #1215 touches, so the two apply in either order. If #1215 is closed rather than merged, its two facts still need a home here.

Every user-visible change in #6002, and where it landed

Behaviour in #6002	Disposition
isDefault is persisted and read, so the open signup control finally takes effect	Already correct, no edit. The page has always described isDefault as working. #6002 makes the existing text true rather than stale, so manufacturing a change here would be noise.
Open signup is applied on every sign-in through the organization's own address, to any non-member, on every sign-in method that address offers	Added as How the open signup invitation is applied at sign-in. The page framed this as first-time registration only; an existing account signing in at a custom domain is the reported journey #6002 fixes.
Applied only to non-members: a member's roles and teams are never re-applied	Added. This is what protects an administrator's deliberate removal of a role or team from being undone by the next login.
Acceptance is idempotent: one person is appended to the accepted list once, however many times they sign in	Added, in the operator's terms: the acceptance count in the Quota column does not climb on repeat sign-ins.
Ordinary ineligibility (disabled, expired, at quota, email not listed) is a silent skip: the person signs in, joins nothing, sees no error	Added as a warning callout with the four properties to check. This is the page's answer to "open signup adds nobody".
An invitation update matching no live invitation of the organization answers not found instead of a false success	Added to Managing existing invitations, described as the stale-edit-dialog case an administrator actually hits.
The invitation dialog surfaces the server's reason instead of "Unknown error"	Added in the same paragraph, as "the dialog reports the specific reason it was refused".
Marker changes require Manage Invitations in either direction; an omitted isDefault preserves the stored value	Covered by #1215, not repeated here.
Edit Organization picker takes precedence; a picker value naming a deleted invitation falls through to isDefault	Covered by #1215, not repeated here.
A picker value naming another organization's invitation also falls through	Not documented. It is a misconfiguration an administrator cannot create through the UI, tracked as meshery-cloud#5994, and describing it would document a defect as behaviour.
Invitation email no longer renders a dangling "invited by " when the inviter cannot be named	Not documented. The page shows the email as a screenshot and never quotes that sentence, so there is nothing here that was false.
The 404 answered when editing at All Organizations scope	Not documented. #6002 records this as a held product question, not settled behaviour.

On the API contract, corrected

The brief for this work said a newly returned 404 is undeclared in the pinned meshery/schemas contract. Checked directly against schemas/constructs/v1beta3/invitation/api.yml at v1.3.44: updateInvitation declares 200/400/401/404/500, so the 404 is in the contract. The undeclared status is the 403 on createInvitation and updateInvitation, and it is already escalated upstream: meshery/schemas#1173 with the fix open at meshery/schemas#1174.

Nothing here states an HTTP status code either way. These pages describe what an administrator sees, so the refusal is written as behaviour ("reports that the invitation was not found", "reports the specific reason") and no undeclared contract is asserted as fact.

Testing

• npm run build clean: 1623 pages, no shortcode or ref errors, and the new {{</* alert */>}} and the User Management cross-reference render correctly in public/.
• markdownlint on the changed file before and after: no new rule classes. The only additions are MD013 line-length, which every prose line on this page (and the repo) already carries.

Summary by CodeRabbit

• Documentation
  • Added guidance for handling invitations deleted by another administrator while an edit dialog is being saved.
  • Documented how open signup invitations are applied during sign-in, including eligibility rules, member limits, expiration, disabling, and email matching.

📝 Walkthrough

Walkthrough

The user invitations documentation now explains concurrent invitation deletion feedback and how the default open signup invitation applies during sign-in.

Changes

User Invitations Documentation

Layer / File(s)	Summary
Invitation behavior guidance content/en/cloud/concepts/identity-and-security/users/user-invitations/index.md	Documents the error shown when another administrator deletes an invitation during editing. Describes open signup behavior for sign-in methods, existing members, quotas, expiration, disabled invitations, and email mismatches.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 43808

The new invitation guidance could mislead administrators by implying that an existing member loses membership when open signup is ineligible; this is a bounded documentation correctness issue requiring a wording follow-up, while the prose-only change remains otherwise mergeable.

Review loop closed. Every comment on this PR has been answered; nothing is left open.

The one review finding. The inline note asking that the no-membership outcome be scoped to non-members was correct and is fixed in 697ed2b, with a reply on the thread. The automated walkthrough's Merge Risk line raises the same point, and it was computed against 43808 (the first commit), so it predates the fix rather than describing the current branch.

Preview verified, not just built. The first publish attempt was queued behind concurrent Pages deployments and 404'd. It is live now and carries all four new passages, with the User Management cross-reference correctly rewritten to the preview path: https://docs.layer5.io/pr-preview/pr-1219/cloud/concepts/identity-and-security/users/user-invitations/

Re-checked against what meshery-cloud#6002 currently carries, since its head moved after this page was written (now 018073b4). Every behaviour documented here still holds at that head, verified in the source rather than in the PR description: the membership guard still runs before the invitation is resolved, so a member's roles and teams are untouched; ordinary ineligibility is still a logged skip that returns without surfacing an error to the person signing in; and an update matching no live invitation of the organization still answers "invitation not found". No correction was needed, so none was invented.

Two things landed on #6002 after this page was written. Neither makes anything here false, and both are recorded rather than quietly absorbed:

• The invitation form's fields were mislabelled with their raw property names, because ui:label is a boolean in RJSF and ui:title is what supplies label text (meshery-cloud#6001). They now render proper labels, and the open-signup control reads Set as open signup invitation. This page names API properties rather than form labels, so nothing here changed, but whoever lands docs(cloud): open signup invitation permission and precedence #1215 may want that label in the isDefault row it edits.
• A separate fix to which fields the form submits: an undeclared key could make the dialog's Save do nothing at all, with no request and no notification. That strengthens the sentence added here about a refused edit reporting its reason.

Not merging. Merge authority for this PR has not been given, so it is left open for a maintainer.
