Allow one committed Worthless to copy an opposing base Shield or Snooper when no actual defense is played, including protection of the selected native trained leader. Expose an optional named public choice after both plans reveal, before traitor calls, and show the activated protection in revealed plans. Discard the chosen physical Worthless once after battle, including winner and traitor-preempted outcomes. Original physical card identities and plans stay intact. Timing and explicit-discard precedence are documented implementation inferences; lower retreat, modified defenses, combined modes and public starts remain guarded. Reuse legal Worthless planning candidates and add a public-information decision path for all four AI profiles. Bind new battle choices to revealed plans, public skill stance, canonical card custody and an independent event, validate saved continuations before reads/actions, omit internal proof fields from views, and retain unmarked legacy-battle behavior. Independent rules/privacy/persistence review found no blocker. Validation: focused Diplomat rules/UI/bot/JSON/SQLite checks plus 80 related legacy checks passed; typecheck, lint, 4537 offline tests, production build and 43 HTTP tests passed. Concurrent copy versus decline, stale/corrupt decisions, self-protection and mandatory traitor-winner discard are covered. Browser genuine assignment and a conserved staged battle exercised human plan submission, refresh of the pending choice, actual Snooper copying with Baliset, Hasimir survival, exactly one Baliset discard, ordinary Crysknife retention and final refresh with private cards and four board forces, fifteen reserves, one Tank and eight spice. Basic/Advanced four-profile samples completed in 210/223 actions with six/seven JSON restores and no rejected candidates; neither encountered an eligible copy, so targeted checks establish the effect. The server was healthy after the power outage. All 563 opening rooms and original seat/recovery records were preserved (597 after QA/HTTP); SQLite integrity and foreign keys passed. No restart, reset or automation was needed. Verified source tree: 868bb7484cef244e6ab20f8d08d62e118629e257870cf91a436bf42651b968f5

Diplomat copied-defense prototype
13 September 2026. Prototyped, with Partial rules coverage. This connects the Diplomat's normal band for canonical base Shield and Snooper defenses only. The lower retreat band, combined modules and other defense cards remain unfinished. Public Leader Skills starts and publication remain gated.
Source and interpretation
The archived physical card says that, when its owner plays no defense, one Worthless card in that Battle Plan may count as the defense the opponent used, and directs that Worthless card to be discarded afterward. Jack Reda repeats the effect in the designer walkthrough at 14:11. The GF9 CHOAM & Richese rulebook, page 9, keeps a normal skill active while its native trainer and card are face up. It also expressly keeps the first band available when that trained disc is selected for battle, if applicable. Page 12 limits a captured skill to its lower band. The archived component photograph and transcript are retained in the local source archive described by the common source contract.
The connected base interpretation therefore accepts one actual Worthless card from either plan slot, or offers a choice when both slots contain Worthless cards. An actual defense makes the skill unavailable. The opponent must have played a canonical base Shield or Snooper; an empty defense supplies nothing to copy. The copied role protects exactly like that base defense without changing the Worthless card's identity or either revealed plan. This lets the selected native Diplomat protect itself: copied protection is resolved first, then the common surviving-trainer rule is evaluated. If the copied type does not stop the weapon, removing the dead trainer's skill does not change that outcome.
Two timing and cleanup rules are explicit implementation inferences. The optional public choice occurs after both plans reveal and before traitor calls, because the copied defense cannot be known when the Worthless card is sealed. The chosen Worthless is always discarded after resolution, including when a successful traitor call preempts ordinary weapon effects. This combines the card's explicit discard instruction with the chosen scheduling point; the publisher sources do not separately address Diplomat versus traitor timing. The November 2020 GF9 FAQ, page 8, supplies the general winner-retention rule, which the chosen card's specific discard instruction overrides in this prototype.
Connected behavior
New supported battles carry a version marker and an independent event-bound receipt. After reveal, the server derives the eligible physical Worthless IDs, opposing defense and live native assignment from current custody. Choosing one records its copied kind; declining records that choice. Either result preserves the original plans and leaves every card in its hand until battle resolution. Legacy battles without the new marker keep their existing continuation and do not gain a retroactive Diplomat opportunity.
The copied base role feeds ordinary weapon survival and existing Poison or Projectile Defense skill checks. The physical Worthless identity remains available to checks such as Warmaster. Only the chosen Worthless receives the mandatory skill discard; a second played Worthless follows ordinary winner or loser cleanup. The receipt is revalidated before views, normalization and actions against battle identity, turn, territory, plans, public skill posture, card faces and unique physical custody.
The decision and its already-revealed card IDs are public. Internal frame, signature and binding fields are not projected. Before joint reveal, ordinary sealed-plan and hand privacy remain unchanged. Human controls name the copied defense and each eligible Worthless card, and allow an explicit decline. All four AI profiles use the public revealed cards and shared legality; no opposing hand or pre-reveal plan is inspected.
Evidence and remaining scope
Sixteen focused checks were observed before the broad checkpoint run. They cover the pure base quote, Basic and Advanced battles, either Worthless slot, two-card choice, same-disc survival, Shield explosion composition, captured discipline strength, decline, controls, all four AI profiles, private/public views, JSON/SQLite restart, concurrent choice, traitor cleanup, corruption and legacy continuation. Independent rules, privacy and persistence review found no blocker in this bounded path. A new isolated browser room used genuine skill assignment before a conserved staged battle. The human sealed Hasimir Fenring, Crysknife and Baliset, restored the pending copy choice, copied an opposing Snooper and resolved. Hasimir survived poison; Baliset was discarded exactly once. Keeping Crysknife and refreshing preserved that private card and traitor, four board forces, fifteen reserves, one Tank and eight spice. This is a targeted browser journey, not full-game acceptance.
Two genuine four-profile Basic/Advanced samples completed in 210/223 actions with six/seven JSON restores and no rejected candidates. Neither encountered an eligible copy; targeted tests and the browser establish the effect. Required broad check results and final saved-game preservation are recorded in the checkpoint commit and private source-bound report.
The lower Diplomat retreat remains pending with its recorded strength and resolution-order questions. Shield Snooper, Chemistry, defensive Weirding Way, Portable Snooper, Carthag-added protection and any future copied or modified defense need a separate contract for whether generic roles or named exceptions are inherited. Homeworlds, Nexus, Discoveries, Stronghold Cards, Tech Tokens and other combined modules remain guarded. These limits preserve the existing public gates.
