From c60b02dbb9575fa97d92d0f65224e0ed700319f9 Mon Sep 17 00:00:00 2001 From: Lior Date: Thu, 28 May 2026 07:29:34 -0400 Subject: [PATCH 1/3] feat(world): world substrate + reusable lifetime-composition helpers (Aaron 2026-05-28 naming substrate + reusability substrate-engineering questions); 14 tests pass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per Aaron 2026-05-28 two substantive substrate-engineering substrate questions: 1. 'do you have to write custom code everytime you compose two lifetimes' → NO; dispatch substrate is reusable; only matrix per-pair; recurring patterns factored via defaultAdvanceMatrix + terminalMatrix + predicateMatrix helpers 2. '(do we still call the shared git flow a lifetime or world or shared space?)' → WORLD (shared substrate where multiple lifetimes interact; different scope from per-substrate-entity lifetime; world contains lifetimes) Naming canon established: - LIFETIME = editable per-substrate-entity DU (Aaron's prior framing) - WORLD = shared substrate where multiple lifetimes interact - GIT FLOW = operational form of the world What this adds: - World interface (registry of lifetime-pair matrices keyed by pair name) - EMPTY_WORLD constant - StandardVerdict discriminated union (advance | block | complete | no-op | escalate-to-operator) — factors out recurring vocabulary so per-pair matrices reuse it instead of inventing parallel verdict types - registerLifetimePair (immutable world update; returns new world) - lookupLifetimePair (registry lookup) - defaultAdvanceMatrix (every-cell defaults to advance; caller overrides specific cells) - terminalMatrix (single-cell complete; other cells from terminal A block) - predicateMatrix (most general; caller predicate per cell) - dispatchInWorld (world-level lookup + dispatch; UnregisteredPair feedback) Re-exports from composed-lifetime.ts (PR #5771) so callers compose with world.ts for both naming + helpers. Tests (14; all pass): - EMPTY_WORLD zero pairs - registerLifetimePair immutable + adds pair - lookupLifetimePair found/undefined cases - defaultAdvanceMatrix every-cell-advance + overrides applied - terminalMatrix terminal+block cells - predicateMatrix caller-supplied dispatch - dispatchInWorld lookup + dispatch + UnregisteredPair feedback - StandardVerdict exhaustive switch (5 variants) - Reusability test: full 9-transition world built with helpers (no per-cell custom code) - Multiple lifetime pairs registered in single world (workflow-review + workflow-encryption) Composes with substrate: - composed-lifetime.ts PR #5771 (base dispatch substrate) - B-0832 civ-sim substrate (game-world; Pauli-exclusion-for-agenda) - B-0867 workflow engine (workflow world) - 13th-ferry §33.7 multi-AI cascade (each AI inhabits the world) - additive-not-zero-sum + honor-those-that-came-before + monad-propagation + asymmetric-authorship rules Substrate-engineering answer to Q1 directly demonstrated: - 'workflow-review world built with helpers (no per-cell custom code)' test exercises predicateMatrix to build full 9-transition matrix in ~5 lines of predicate code;

(Same fix as PR #5775.) 3+6. World.registry type-safety scope-disclosure: added explicit docblock to `World` interface naming the `unknown`-erasure limitation on lookupLifetimePair/dispatchInWorld, the consequence (caller can register one verdict type + lookup with a different T without compile error), AND the substrate-engineering target (typed `PairToken` + definePair/registerPair/lookupPair surface; existing string-keyed surface stays as escape-hatch). PoC-scope deferral documented honestly so future-substrate-engineering reading the code sees the gap + the path forward without re-deriving it. Additionally: generalized `registerLifetimePair` signature to `` so callers passing specialized subclasses (GitWorld / GitHubWorld / etc., introduced in downstream PRs) receive the SAME specialized type back with subclass fields preserved via spread. Returning bare `World` here previously dropped subclass fields silently under structural typing. Added regression test using inline SpecializedWorld extension. 7. Exported `WorldTransitionFeedback` + `WorldTransitionResult` union types: `dispatchInWorld` previously returned an inline-extended `TransitionResult | { ok: false; feedback: {...UnregisteredPair...} }` shape — callers had to do ad-hoc narrowing; downstream exhaustive switches couldn't name the complete world-dispatch feedback type. Now: `WorldTransitionFeedback = TransitionFeedback | { kind: "UnregisteredPair"; pairName: string }` (composes base composed-lifetime feedback variants + the world-scope addition); `WorldTransitionResult` is the result-shape; dispatchInWorld returns the named type. Added regression test exercising exhaustive switch over all four WorldTransitionFeedback variants. Re-exported `TransitionFeedback` from world.ts so downstream callers compose with the full feedback substrate from one module. Tests: 16 pass (14 existing + 2 new: subclass-preservation regression + WorldTransitionResult exhaustive-switch regression).
