+## P8.1 Owner Acceptance
+
+On 2026-08-12 the Owner reviewed the published Contract/difficulty entry and
+terminal creation-receipt views and responded that this is the intended package
+and it is acceptable. P8.1 comprehension and visual acceptance are therefore
+Owner-accepted for advancing to P8.2. This does not grant audio, runtime,
+device, packaging or release acceptance.
+
+## P8.2 Owned Scope
+
+- Begin from the accepted P8.1 receipt with 52 Coin, Company two and Line
+  capacity four.
+- Show three stable Recruit offers and keep at least two level-1 base
+  Professions affordable without recommending one.
+- Complete two separate inspect, review, confirm and receipt transactions.
+- Apply the authority formula `hire_list_price(1,0) = 14 Coin`, producing
+  balances `52 -> 38 -> 24` and Company counts `2 -> 3 -> 4`.
+- Expose individual `LV 1 / XP 0` and exactly one starting item per offer.
+- Buy one tier-0 Region-1 equipment item for 12 Coin and add it to run
+  inventory without silently equipping it.
+- Compare and apply one one-slot replacement; return the prior item to run
+  inventory atomically.
+- Reorder the four-Recruit horizontal line using tap Recruit then tap target;
+  protected rear stays left and exposed position zero stays right.
+- Stop at a preparation receipt that names Company, Coin, inventory, order and
+  the locked P8.3 Risk handoff.
+
+## P8.2 Acceptance
+
+1. No offer is preselected or labeled recommended; inspecting changes no
+   ownership or Coin.
+2. Each hire has its own stable offer ID, review, explicit 14-Coin confirm and
+   one receipt; double input cannot duplicate either transaction.
+3. Company and capacity remain distinct through exact visible states
+   `2/4`, `3/4`, `4/4`.
+4. Recruit surfaces show individual level/XP and one starting item.
+5. Equipment purchase costs exactly 12 Coin, creates one inventory ownership
+   change and equips nothing automatically.
+6. Equipment replacement leaves one equipped item and returns the prior item
+   to inventory in one receipt.
+7. Party order changes only after a legal source and destination selection;
+   undo restores the prior order before final Save Order.
+8. The terminal receipt reflects `12 Coin`, Company four, complete order and
+   stops before Risk.
+9. Desktop, landscape phone and portrait phone preserve all choices, balances,
+   selected state and primary actions without horizontal overflow.
+10. P8.1 and the complete Phase 7 atlas remain valid.

+
+## P8.2 Transaction Rules
+
+- `hire_list_price(1,0) = 14`; each hire owns a different offer ID and receipt.
+- Equipment tier zero in Region band zero costs `12 + 3*0 + 6*0 = 12` Coin.
+- Buy adds the item to inventory. Equip is a later, separate transaction.
+- Each Recruit still owns exactly one active item. Apply returns the prior item
+  to inventory and equips the candidate atomically.
+- Company count is ownership; Line capacity is simultaneous deployment. Hiring
+  changes only Company count until capacity is full.
+- Order runs protected rear-left to exposed front-right with position `0` at
+  the right. Locale never mirrors it.
+- No combined `Hire two`, recommended Recruit, automatic equip, automatic order
+  or hidden price adjustment is legal.
