Depends on #109 and its API prerequisites. Merge those first and rebase before merging. Isolated commit 235b8f975f9e4c74cf0775dc6f18e9cc7220439b (focused diff).

Extend the bounded portable script language with give_money, take_money, check_money, take_coins, check_item, take_item, check_dex_owned, mark_seen and heal_party. Resolve canonical item/species IDs through the existing loader index. Validate the whole program's arguments, content and referenced live stores before any prefix runs, including unreachable rows; revalidate stores when executing after a wait.

Use native Bag.remove/order cleanup and Pokemon healing with the current Game's moves for PP. The optional moves argument preserves existing Pokemon.heal callers. Preserve the verified Gen1 API's wallet semantics: Gen2/3 cap addition at999999, Gen1 retains its native uncapped wallet, with host exact-integer overflow refusal. Removal saturates at available quantity/zero; no gift UI is introduced in this synchronous group.

Commands, bounds and reproduction.

Validation

• 118/118 targeted checks, including real native Bag removal/order cleanup and Pokemon HP/status/PP restoration, canonical content, malformed/unreachable-row refusal with no prefix effects, wallet caps/overflow, saturation, copied arguments and changed live stores.
• 88 cross-engine comparisons /176 isolated loader runs against clean pinned Gen1 79ea62f45fb2ea8f65d081a109431e4eb1bbdb36, clean feature head. Same public-only program on Red, Blue, Yellow, Gold, Silver, Crystal, FireRed and Emerald. Compare resulting money, coins, item quantity, seen state, HP/PP and conditional branches through the actual native save/bag/party backends.
• Existing portable dialogue5268, script flags134 and native flag18348 checks remain passing.
• Full ROM-free run: 84/94 engine, SDK3/3, B30 PASS. All 27 complete FAIL lines equal the fresh series baseline exactly, in order.
• All-PR integration through Add prevalidated portable flag script commands #109 plus this commit (04ea058693a1801013343db1d09813eb2bc0e927): 89/99 engine, SDK3/3, B30 PASS; same exact baseline failures. All88 comparisons/176runs pass on that clean combined tree.
• Changed modern Lua formatting and diff checks pass; the tiny native heal signature extension keeps surrounding formatting. Fixtures are synthetic and ROM-free, not a story/render playthrough. Effects before a later runtime failure are not rolled back.

Unchanged failing suites: gate_fingerprint, gate_meta_coverage, quit_thread_shutdown, rebind_capture_bug510, rebind_swap_clear_bug589, soft_reset_bug563, tool_mod_hooks, update_check_tests, update_tests, wide_battle_layout; full test entry remains nonzero.

Hosted CI

Published open/non-draft at the tested head. API 3 contracts and ci currently conclude action_required pending maintainer fork-workflow approval. Hosted CI is not green; validation above ran locally.
