PlanExecutor

Execute compiled AttributePlans against validation data.

Architecture overview

Hypervel's validation uses compiled execution with a delegated subclass path:

1. Rules are compiled into AttributePlans by RuleCompiler — each rule becomes either an InlineCheck (fast, match-dispatched) or a DelegatedCheck (calls the existing validate*() method). Plans are cached worker-lifetime by RulePlanCache for Swoole performance.

2. Safe first-position exclusions are resolved before execution, and wildcard database-presence candidates are queried in ordered groups. Unknown values remain on the ordinary verifier path.

3. The exact Validator executes optimized plans through a branch-free loop. Subclasses use a Laravel-shaped loop over delegated checks so their validation and stopping hooks remain authoritative.

Maintenance notes

• Adding a new inline-eligible rule requires review in 4 places: CheckType (enum case + ruleName), RuleCompiler::tryInline(), executeInline() below, and canPreflightInline(). Omitting preflight support is correctness-safe but prevents presence batching across that rule.
• DelegatedChecks require zero changes — they call validate*() directly.
• executeInline() arms must match the exact behavior of their corresponding validate*() methods in ValidatesAttributes. When an upstream method changes, the inline arm must be updated to match.

Mixed into Validator so it can call existing helpers on ValidatesAttributes (sizeOf, isValidEmail, compareDates, etc.) and access validator state ($this->data, $this->rules, $this->currentRule, etc.).
