Truthtrance: compound shipment promises

14 September 2026. This extends the reserve-shipment prototype with shipment-only AND/OR questions. Public mode and publication gates remain unchanged.

Mixed current facts and future shipment — 3 October 2026

The structured builder now supports bounded nested AND/OR trees containing current named-card, card-count, inventory, traitor, personal-spice, physical-force or knowledge facts alongside reserve-shipment conditions. Both kinds must be present; the existing software limit is sixteen logical leaves and four grouped levels, not a printed limit on game questions. Current fact legality comes from the existing fact parser; reserve shipment uses the original destination/count quote and the same active-unused-shipment/mode boundary.

Evaluate current facts when a definite answer is given and freeze their three-valued results privately. Later legal card/force/spice changes cannot rewrite the past statement. Future leaves still describe one eventual reserve shipment or its absence, and the whole expression must match the public answer. For example:

• Yes to “I currently hold at least10 spice OR I will ship4 to Arrakeen” with20 spice permits later spending and no shipment.
• No to “I currently hold at most10 spice AND I will ship4 to Arrakeen” with20 spice permits shipment even if its cost later reduces the wallet to5.
• Yes AND with a true current clause still requires the future shipment. No OR with a true current clause is impossible.

Unknown current information stays unknown: it is not converted to false for a No promise. A definite answer is available only when an actually legal future outcome makes the whole statement definite. Multiple ordinary and mixed promises constrain that same event together. Voluntary spending cannot remove the last legal completion, but need not preserve a current holding that was not itself a future promise.

Only the respondent receives a mixed promise's compiled fixed answers and private feasible choices. Public question/history text keeps the original grouping and whole answer, never which current clause matched. Shared shipment, skip, preparation, release, controls and minimal legal policies use the same frozen expression. Default public parsers reject caller-supplied constants.

The existing FAQ whole-question semantics and historical/current distinction support this composition; it is not a new expansion or timing ruling. Earlier phases, other future actions, expansion shipment modes and arbitrary prose enforcement remain outside the bounded implementation.

Twelve actual programs cover mixed truth/skip/shipment/changed-spice, all four legal policies and a second joint pure+mixed promise. The affected truth/ship/discard rule batch passes88/88; mixed/reference23/23, types/lint and build pass. Human390px 4PVKRRWB v10 authored and answered the actual OR claim, then spent all20 spice as a bribe, skipped shipment and fulfilled the promise while the public answer stayed Yes. This is bounded local evidence, not complete Truthtrance, module or deployed acceptance.

Meaning and authority

The GF9 November 2020 FAQ, printed page 8 permits AND/OR questions and binds definite answers while compliance remains possible. Each condition here describes the same eventual reserve shipment in the active opportunity, using a destination and minimum physical force count. The original shipment-only form does not promise two shipments; the later mixed form above adds current facts without turning them into future holdings.

AND is true only if every condition matches. OR is true if any condition matches. A No answer negates the whole expression: No to AND requires at least one false condition; No to OR requires every condition to be false. Skipping shipment makes all these positive shipment conditions false. Separately answered questions must all be honored together.

For example, Yes to “at least six to Carthag OR at least four to Arrakeen” permits either branch. No to that same question permits fewer than six to Carthag, fewer than four to Arrakeen, another destination or no shipment. AND with two different destinations cannot be fulfilled by a single shipment, so Yes is unavailable.

Connected prototype

The question form adds a second destination/count condition and an AND/OR choice. The shared engine expression supports grouping within software limits of sixteen leaves and four nested groups; the first visual builder exposes two conditions. Existing flat questions and saved promises retain their meaning. Public question/history text preserves grouping, while answer feasibility and suggested preparations stay private to the respondent.

The completion search considers every relevant destination, physical count and legal sector, with the same controlled preparations and funding as single promises. It evaluates the entire expression and all earlier promises together. Actual shipment, skipping, voluntary spending and opposing-effect release use the same evaluator. A fulfilled promise records the shipment event and survives later movement or casualties.

All four AI profiles rank the projected feasible answers using only public destination value and their own reserves. Strategic preference never determines whether an answer is possible. The existing complete continuation remains the fallback when a strategic shipment shortlist misses a legal route.

Evidence and remaining scope

Focused engine, controls, AI and authenticated SQLite cases cover whole-expression truth, alternative destinations, old saves, joint commitments, custody, private restoration and duplicate actions. Final results and source fingerprints belong to the private checkpoint report and Git message.

The isolated browser used genuine base setup before conserved turn-two staging. The human asked “twenty to Carthag OR four to Arrakeen.” The respondent's legal AI policy answered Yes, and the public grouped question/answer survived refresh. Its next AI action shipped four to Arrakeen, spent four spice and fulfilled the aggregate promise once. All six accepted actions replayed exactly; all private views, card/force custody and the original seat row were preserved. This is a targeted browser scenario, not a complete human game.

The existing active-unused-shipment scope remains: base Basic, and supported base Advanced games without Guild or optional modules. Mixed current-fact/ shipment trees now use that same opportunity. Earlier timing, other future actions, expansion shipment combinations and arbitrary prose remain unfinished. This prototype does not settle pending material rulings or certify complete Truthtrance.
