Prototype Discovery spice encounters, private tokens and stash rewards

Connect real Basic/Advanced base-faction audit setup to all seven Discovery
Spice Cards and eight physical tokens. Add Great Maker's ordered majority
vote and Fremen reserve ride, destructive Discovery blows, private faction
peeks and Collection inspection/reveal, stash rewards and mandatory saved
card overflow, and revealed nested board locations. Share private legal
choices with human controls and all four AI profiles. Preserve normal gates.

Independent review repairs orphaned worm/vote/ride controls, retargeted
reserve arrivals, actor bindings and incomplete overflow discard receipts.
Harden room-aware admission against unrevealed nested locations. Extend the
backed-up local prototype starter with a Discovery profile; preserve seats.

Still missing: next-turn free entry, five special location benefits and
Ornithopter movement spending. Current prototype playthroughs do not certify
those effects or complete module/expansion compliance.

Verification: npm run check passed 4264 offline tests plus types/lint;
npm run build passed; npm run test:integration passed 40 tests. The single
source-bound broad run took 129358ms / 6782ms / 23918ms respectively.

Two seeded Basic/Advanced games complete with component custody intact.
SQLite races pay stashes once and resume committed discards without replay.
Browser 3RJBH26Y verifies genuine human Fremen setup, a Discovery blow from
one reordered physical card, native private Hiereg visibility, enlarged
card/rules reading and refresh. Room remains paused at spice acceptance.
All 125 opening saved rooms unchanged; 31 added, 156 total. No server restart.

Efficiency: three reused bounded helpers; aggregate counter 60591430 to
61812513 after verification, 1221083 tokens before final Git/push overhead.
47 added offline tests. One stable broad run after focused review fixes;
no calibration or exhaustive optional-module interaction matrix.

 # Dune implementation status
 
+## 13 September 2026 — First connected Discovery prototype
+
+Connects genuine base-faction Basic/Advanced audit setup to all seven sourced
+Spice Cards and eight opaque physical tokens. Great Maker resolves worm effects,
+an ordered majority vote and a free Fremen reserve ride. The six Discovery blows
+destroy prior forces/spice before their new blow and separate token placement.
+Private faction peeks and Collection inspection/reveal lead to exact stash
+rewards, a saved full-hand draw/discard choice, carried Ornithopter custody and
+five public nested locations; only Jacurutu contributes stronghold victory.
+Shared human/AI controls and JSON continuations accompany the actions.
+
+This is Prototyped progress with Partial coverage. Next-turn free entry, the
+five special location benefits and Ornithopter spending remain missing. The
+normal public module start gate stays closed. Great Maker first-turn skipping,
+Sandtrout suppression and empty-token-supply behavior remain identified source
+inferences for refinement, not new confirmed rulings. See the
+[prototype boundary and dependency queue](DISCOVERY_PROTOTYPE.md).
+
+Focused component, runtime, Great Maker, board/admission, private-control and
+SQLite recovery checks pass. Two seeded Basic/Advanced games finish while
+preserving components; browser `3RJBH26Y` verifies genuine Fremen setup, a real
+Discovery blow, native private peek and enlarged card guidance. Review repaired
+lost encounter/arrival controls and an unfinished overflow discard. Broad
+verification and preservation results are recorded in the checkpoint commit
+and private source-bound report. No complete-module certification is claimed.

 ## 13 September 2026 — CHOAM Nexus Collection prototype and Discovery inventory
 
 Adds the missing absent-CHOAM Secret Ally Collection trade through the engine,
