 **Direct ID lookup**: Add `wikicfp_id: "<event_id>"` to a venue entry in `venues.yaml` to skip the search and fetch that page directly. This avoids wrong matches on common acronyms. Verified IDs for the cloud-edge topic:

+A venue whose `deadlines.yaml` entry says `source: manual` is skipped by the fetcher regardless of its `wikicfp_id`; the ID is kept so the lookup still works if the entry is ever handed back to WikiCFP.
 
 **Skipping search**: Set `wikicfp_id: false` to skip WikiCFP entirely for a venue (e.g., ATC, SC, SEC — where the search returns wrong events). Deadlines for these must be filled manually.

+### Multiple Submission Cycles
+
+Many systems conferences run more than one submission round per year, all feeding the same event. Recording only one round makes the site claim a conference has been missed when a later round is still open. Give such a venue a `cycles` list instead of top-level deadline fields:
+
+```yaml
+EuroSys:
+  source: manual
+  event_dates: Apr 19-23, 2027       # event fields stay at the top level
+  location: Rabat, Morocco
+  cfp_url: https://2027.eurosys.org/cfp.html
+  cycles:
+    - name: Spring                    # free text, verbatim from the CFP
+      abstract_deadline: May 7, 2026
+      submission_deadline: May 14, 2026
+      notification: Aug 21, 2026
+      camera_ready: Sep 25, 2026
+    - name: Fall
+      abstract_deadline: Sep 17, 2026
+      submission_deadline: Sep 24, 2026
+      notification: Jan 29, 2027
+      camera_ready: Mar 5, 2027
+```
+
+Cycle fields are `name`, `abstract_deadline`, `submission_deadline`, `notification`, `camera_ready`, plus an optional per-cycle `cfp_url` where a venue publishes a separate call per round. Everything else (`source`, `event_dates`, `location`, `cfp_url`) describes the event and stays at the top level.
+
+**Single-round venues need no change.** `load_deadlines()` folds a flat entry into a one-element `cycles` list on read, so the two shapes are interchangeable and only genuinely multi-round venues need the extra nesting.
+
+What the generator does with cycles:
+
+| Output | Behaviour |
+| --- | --- |
+| Venue page | Multi-cycle venues get a **Submission Cycles** table with every round; the next open one is bolded and marked `(next)`. Single-cycle venues keep the **Upcoming Deadline** block unchanged. |
+| Venue index | One row per venue, showing the next open cycle with its name appended to the paper deadline. |
+| Calendar table | One row per cycle, with a `Cycle` column, sorted by paper deadline. |
+| Calendar grid | One event set per cycle; titles read `EuroSys Fall — paper deadline`. Elapsed cycles are kept — the grid is time-indexed, so past rounds only show when you navigate back to their month. |
+| Front matter | `next_deadline` / `abstract_deadline` / `notification` / `camera_ready` reflect the **next** cycle. Multi-cycle venues additionally carry `cycles` and `next_cycle`. |
+
+"Next" means the earliest cycle whose paper deadline has not passed; if every round has elapsed, the last one, so a page shows the most recent round rather than going blank.
+
+**WikiCFP cannot express this.** It lists one deadline set per event, so a multi-round venue fetched from WikiCFP will silently record whichever round WikiCFP happens to hold. Research such venues from the CFP itself and mark them `source: manual` — otherwise the next fetcher run overwrites the extra rounds. SoCC, Middleware and IPDPS were converted this way even though they still carry `wikicfp_id` in `venues.yaml`.
