Discussion threads & decision notes

Two distinct surfaces

Surface	Purpose	Who writes it	Where it shows
Discussion thread	Back-and-forth conversation. Multiple comments, edits, deletes.	Both owner and approvers	Discussion section on the approval detail page (owner) and queue card (approver)
Decision note	One-off reasoning attached to an approve or reject.	Approver only, at decision time	Status panel on the detail page; included in the approve/reject email to the owner

Use the discussion thread for "is this link right?" "fix the typo on line 2" — anything that warrants a back-and-forth. Use the decision note when you actually click Approve or Reject and want to explain why.

Discussion thread features

• Avatars and relative timestamps ("5m ago")
• Edit your own comments — hover over your message, click the pencil icon. The comment shows "edited" after.
• Delete your own comments — same hover area, trash icon. Permanent, no undo.
• You can't edit or delete other people's comments (UI-gated and RLS-enforced)
• Email notifications fan out on every new comment to the other party (owner ↔ approvers)

Decision notes

When an approver clicks Reject, a note is required so you know what to fix. When they click Approve, a note is optional (e.g., "LGTM").

Notes appear:

• In the rejection / approval email you receive
• On the approval detail page, in the colored Decision panel (red for reject, green for approve)
• On the approver queue when re-reviewing an edited post — the previous reviewer's note is shown as an amber callout for context

Tips

• Threads are scoped to one post. Each scheduled post has its own discussion. There's no inbox of comments across posts.
• Comments don't decide. Only the Approve/Reject buttons change the post's state. If you need a thread to wrap up with a decision, the approver still needs to click one of those.
• Email throttling isn't implemented yet. A rapid back-and-forth fires one email per comment. Use sparingly with chatty threads.
