+**Start bound to a level** (2026-11-07): a start with "@ world/chapter"
+(`BootToLevelMod.formatStart(world, chapter, …)`) is used only while `world`/`chapter` name that
+level; for any other level it is ignored with a progress note ("Player start ignored: it was set
+for world W chapter C") instead of failing with "no collision floor" (a play-test whose restore
+never ran left its start in config.json, and every later apply for another level failed). A start
+without "@" applies to whatever level is chosen (old configs, hand-typed values) and is still
+checked strictly. Tests: `BootToLevelModTest.startOfAnotherLevelIsIgnored`, `parsesStartLevel`.
+The editor's play-test (`PlaytestRunner.install`) should write the bound form – see the report.
