Prototype Jacurutu income, Testing Station and Shrine effects

Connect automatic unambiguous Jacurutu physical-force income, a sole-occupant
Testing Station storm choice and Shrine reciprocal physical card roles to
engine actions, player controls, legal AI and saved continuation. Preserve
Weather Control exclusion, exact card/force custody, private hand boundaries
and committed effects after restart. Shared role checks cover existing ordinary
and special Karama paths; reserved cards cannot enter another pending use.

Keep Orgiz, mixed-force Jacurutu allocation and contested Cistern/Testing
Station benefits explicitly pending. These are bounded prototypes; complete
Discovery/Advanced/expansion and publication gates remain closed.

Validation: types, lint and 4,345 offline tests passed (32 added), production
build passed, and 40 HTTP tests passed. Independent cross-reviews repaired
reserved-card deadlock, physical-card selection, alternate-role permission,
storm source/token binding and public-entitlement bot ordering. The first broad
run found five failures; focused repairs preceded the stable repeated check.

Browser A5EJQ2W4 used genuine Discovery setup/reveal/free entry with targeted QA
positioning. A human increased storm movement from two to three sectors,
moving sector 6 to 9. Refresh restored station forces and the private Snooper.
This was targeted control/recovery evidence, not an unmodified full game.
All 187 opening saved rooms remained unchanged; 31 QA/HTTP rooms were added
(218 total). Reused the running server; no restart or save reset.

 # Dune implementation status
 
+## 13 September 2026 — Discovery location effects prototype
+
+Adds automatic unambiguous Jacurutu battle income, an owned Testing Station
+storm adjustment and physical Shrine card substitution through existing Karama
+and Truthtrance paths. Decisions and committed effects preserve JSON/SQLite
+continuation, physical custody and private information. Testing Station cannot
+change Weather Control; Jacurutu counts opposing physical losses, not the wheel
+alone. See the [prototype scope and rulings](DISCOVERY_PROTOTYPE.md).
+
+Orgiz, contested Cistern/Testing Station and mixed-force Jacurutu remain pending.
+Normal module/Advanced starts and publication stay gated. Targeted browser room
+`A5EJQ2W4` exercises station choice and refresh after real setup/reveal/entry with
+QA positioning. Independent review and focused regressions cover all three
+functions; required broad results, source fingerprint and preservation of all
+187 opening rooms are recorded in the checkpoint commit and private report.
+
+The preceding `ab0ab52` entry/flight checkpoint passed 4,313 offline tests, build
+and 40 HTTP tests. Its outage recovery and 156-room opening baseline are historical
+results; the current batch keeps every game created afterward.
