 - Workspace reads are resolved server-side through scoped query services; browser interop remains for browser-only concerns such as session storage, SSE wiring, and DOM helpers.
 - Live workspace refreshes now compare separate roster, per-character sheet, and log versions so unrelated state changes do not force a full roster + sheet + log reload.
 - Workspace campaign data is loaded in bounded slices: visible campaign summaries, a selected campaign roster, a selected character sheet, and a 25-row incremental log window backed by `/api/campaigns/{campaignId}/log/page`.
-- Campaign log rows now ship compact summary data first and lazy-load dice + breakdown detail through `/api/rolls/{rollId}` only when a row is expanded.
+- Campaign log rows now ship compact summary data first, including structured special-event badges for wild dice spikes, natural 1/20 results, and Rolemaster rare/fumble triggers, and lazy-load dice + breakdown detail through `/api/rolls/{rollId}` only when a row is expanded.
+- Newly appended campaign-log rolls auto-expand in the play workspace, with the roll response reused as the initial detail payload for the local roller to avoid an extra detail fetch.
 - Hot API contracts share a source-generated `System.Text.Json` context, and HTTP JSON responses are gzip-compressed when the client advertises support.
 - OpenAPI contract source remains at `openapi/RpgRoller.json`.
