+## Mission names
+
+Mission packages and the mission menu share `Iron Coast S<stage> M<mission>: <title>`.
+Stages use S1 and S2; mission numbers are zero-padded within each stage. The
+campaign packages are **Iron Coast S1: Complete Campaign** and
+**Iron Coast S2: Black Tide**. Stable package IDs, mission IDs and dependency
+IDs retain their original spelling.
+
+| Stage | Mission | Display name |
+| --- | --- | --- |
+| 1 | 01 | Iron Coast S1 M01: Breakwater |
+| 1 | 02 | Iron Coast S1 M02: Tidal Relay |
+| 1 | 03 | Iron Coast S1 M03: Saltworks Convoy |
+| 1 | 04 | Iron Coast S1 M04: Stormwall |
+| 1 | 05 | Iron Coast S1 M05: Cinder Docks |
+| 1 | 06 | Iron Coast S1 M06: Iron Crown |
+| 2 | 01 | Iron Coast S2 M01: Nightbreak Inlet |
+| 2 | 02 | Iron Coast S2 M02: Undertow Run |
+| 2 | 03 | Iron Coast S2 M03: Stormglass Refinery |

+These labels also identify the standalone Stage 2 campaign entries. The Stage 1
+campaign is **Iron Coast S1**, whether Breakwater is enabled alone or the full
+six-mission assembly is selected. Artwork, scripts, objectives, waves, rewards
+and equipment are unchanged by this naming update.
+
+Changing these display labels changes package content hashes, including when
+package versions are unchanged. Existing pilots therefore show the normal changed-mod
+confirmation. Accept it only when ready to use the updated packages; stable IDs
+preserve equipment and progression, and the game keeps its normal original-save
+backup before the next write. This update does not modify pilot files.
