Compose independent cards with Discovery and optional Nexus

Connect original selected-deck Discovery setup, optional Nexus/World/Skills/phase modules and physical card consumers through shared public capabilities. Retain Cunning revealed-location arrival, Sandtrout suppression, paid nested R/Harass and actual later Recruits revival. Preserve native trained-capture and unrelated-preview boundaries.

Validation: frozen 15-file118/118, types/lint/build and six finite original-action/rendered-control programmes; four minimal legal policies. External smoke corrections changed no application source. Existing persistent notices also rechecked23/23. Full combinations, assurance and deployed acceptance remain open; no saved-game, restart or deployment operation.

+
+Fresh selected36/38/50 and original Discovery7/8 now compose with or without
+Nexus12 and original optional World/all14/phase modules. Shared public
+capabilities retain native setup and card consumers across transient encounters.
+Actual reveal/free entry/Cunning, original Sandtrout suppression, paid nested
+R/Harass, typed World returns and earned Recruits revival have source programmes.
+Bounded review corrected two no-Nexus Duke quote admissions while preserving
+trained native-E3/Harkonnen exclusion. No new numerical rule.
+
+Frozen15-file118/118, types/lint/build and six original-action/rendered-control
+programmes pass, with four minimal legal policies. External smoke label/selected-
+control assumptions were corrected against unchanged application source.
+[Canonical source, action counts and limits](NEXUS_CARD_RULES.md#independent-cards-with-discovery--18-october-2026).
+No saved-room/reset/restart/deployment or complete-mode assurance claim.
