/**
 * The constitution resolver computes which project-level guidance files every
 * Diablo agent step receives. A constitution is the stable, project-local
 * governance layer: architecture boundaries, testing expectations, domain
 * vocabulary, ADR references.
 *
 * Pure (no I/O): the caller supplies a file-existence predicate so the
 * resolver is unit-testable without filesystem mocking.
 *
 * Resolution order:
 *   1. AGENTS.md (or CLAUDE.md as fallback) — the repo's agent guidance file
 *   2. CONTEXT.md — domain/architecture context
 *   3. Configured extra files from diablo.config.json constitution.files[]
 *
 * Default convention files are optional and skipped silently when absent.
 * Configured files are intentional — a missing configured file throws.
 * Deduplication preserves first-occurrence order.
 */
/**
 * Resolves the ordered list of constitution file paths for a project.
 *
 * @param fileExists  Predicate returning true if a path exists on disk.
 * @param repoRoot    Absolute path to the project root.
 * @param configFiles Optional extra file paths from diablo.config.json
 *                    (relative to repoRoot). Each must exist.
 * @returns Deduplicated list of absolute paths, in injection order.
 * @throws If a configured file does not exist.
