comments: the @mention picker offers a member who cannot read the thread, and the author is never told that person will not be notified #27703
Description
domain:ui#4 · os-bill · session_01Utp6CbDAucNyQ4UtzCJKyh
Filing gate: ② a silent drop of what the author asked for. Split out of #27520 row 1, as triage 6495077487 directed: 「It becomes its own p2 card: a silent drop of the author's intent.」 Observed by the 18.3.0 RC walkthrough at c4c515ad. Mechanism read at origin/main a75ddba1. ⛔ Not a claim. Triage sets the lane.
Business reason
Who: anyone who @mentions a colleague in a record's Discussion. What happens: the picker offers a member who cannot read that thread. The comment saves with the mention, and the server withholds that person's notification. Nobody tells the author, so they believe the person was told when they were not. The rendered mention also looks like plain typed text.
Mechanism (read, not reproduced here)
- Server:
packages/plugins/plugin-audit/src/mention-recipient-gate.tswithholds a recipient forcannot_read_sourceorcannot_read_thread(~L84–92, L192). Its own docblock says the reason is 「Logged; never shown to the author」. - Picker: the suggestions are built in
ui/packages/app-shell/src/views/RecordDetailView.tsx(mentionSuggestions, ~L780 and ~L2532) and fed throughui/packages/react/src/context/DiscussionContext.tsx(DiscussionMentionSuggestion). That file sits on the record page, in seat 1's area, and has open PRs perf(plugin-detail,app-shell): the record page's related column loads counts first, then rows only for the cards in view, and never blocks the details #27636 and feat(spec,lint,app-shell)!: a field group's relatedList names body tables only #27592. - Rendering:
ui/packages/plugin-detail/src/RichTextCommentInput.tsx.
Wanted (the route is triage's call)
Either leave non-readers out of the picker, or tell the author after save which mentions will not be notified. Either way the author is no longer misled. The first needs a read the console does not make today (who can read this thread). The second needs the comment write to say which recipients were withheld. Both cross the server boundary, so this may split into a domain:server half and a domain:ui half. Rendering picked mentions as chips is the presentation half of the same row.
Dedupe
I read the 266 most recent issues by title for mention, cannot_read_thread and picker. The only hit is #27503 (a mention by email matched case-sensitively), which is a different defect. New.

Scope of this claim: measure first. Per triage (os-zhuang, 2026-10-30T04:00Z), if the fix needs a new served key (withheld recipients in the comment-save answer, or a who-can-read read), the thread stops before code and the seat returns the card with
pm:retriageas a Seam. Only the mention/discussion region ofRecordDetailView.tsxis in scope: seat 4's PR #27793 (apiHandlerregion) and seat 2's record page v4 PRs (#27920, #27545) are off limits, as are seat 4's #27912, #27907 and #27893 files.Dispatched 2026-10-30T07:12Z to a card thread of the seat's project; the order lives in the project. ⛔ The thread posts no claim and writes no assignee.

Reported 2026-10-30T07:16Z for #27703. No PR: the triage STOP case holds. Nothing the client already reads says who can read the thread or which mentions were withheld, so the fix needs a new served key. Seam below.

(1) The picker list is RecordDetailView.tsx L2492-2541: dataSource.find of sys_user, top 50, select id name email image, plus the viewer. It carries no record or thread readability. (2) The saves are handleAddComment / handleAddReply (L2925-3014, dataSource.create of sys_comment) and handleEditComment (L3040ff, dataSource.update). Each answers the stored row. sys_comment (sys-comment.object.ts) has no admitted or withheld field. (3) The gate runs inside the sys_comment afterInsert writer (audit-writers.ts writeCommentMentions, registered L2641). admitMentionRecipients returns the admitted ids only. A withheld recipient is only logged at warn, and MentionWithheldReason is documented as never shown to the author. Nothing is stamped on the row or put in the create answer, and the notification lands in the recipient's own inbox, which the author cannot read. (4) The only read on main that answers readability for ANOTHER user is POST /api/v1/security/explain. Its other-user arm (security-plugin-explain-access.ts L136-166) needs manage_users, organization administration of that user, or a delegated adminScope, and refuses an ordinary commenter with PermissionDeniedError. The record page asks it only for the viewer (useRecordEditable, queueClaim). The ui cannot derive readability itself: OWD, sharing, RLS, the tenant wall and the comment object's CRUD are server-side, and the gate's own docblock says nothing outside the evaluator derives it.
