Keep container-resolved Eloquent models fresh - #528
Conversation
Hypervel auto-singletons unbound concrete classes for the worker lifetime. Add an inherited Transient marker for mutable class hierarchies whose unbound resolutions must remain fresh. Exclude transient concretes from both shared-resolution coordination and auto-singleton publication. Explicit singleton, scoped, bind, instance, attribute, alias, extender, callback, and parameterized-resolution behavior remains authoritative.
Pin fresh make and PSR get behavior, inherited marker semantics, explicit singleton, scoped, and instance precedence, and per-instance extenders. Exercise concurrent transient construction through a yielding dependency to prove that transient misses neither coordinate nor converge on a worker-shared object.
Make Eloquent Model implement the inherited Transient lifetime so application models resolved through the container cannot retain mutable state across requests or coroutines. Cover the ResolvesRouteDependencies path directly. Before this change, a controller-injected model could carry exists=true and prior attributes into the next request, allowing an intended insert to update the previous request's row. The regression also proves ordinary unbound services remain auto-singletoned.
Exercise two implicit bindings through the same container with a stateful model receiver. Each binding must resolve a fresh model so custom route-binding state cannot leak into a later request.
Exercise repeated RouteBinding::forModel calls through one container with a receiver that rejects reuse. This pins fresh Eloquent model construction for explicit model binders as well as implicit bindings and injected route dependencies.
Describe when to use the Transient marker, how explicit registrations retain precedence, and why Eloquent models inherit the lifetime without changing query hydration or metadata caches. Call out captive transient dependencies in longer-lived consumers and add the concise migration signal to the existing Laravel container-lifecycle guidance.
Teach future framework work that unbound Transient and SelfBuilding classes bypass auto-singletoning, while explicit registrations still decide their lifetime. Record that Eloquent models inherit Transient and include the marker in container binding and worker-state guidance so new mutable hierarchies use the lowest correct lifetime boundary.

| A transient dependency injected into a longer-lived service is retained by that service. If the service needs a fresh instance for each operation, resolve the transient dependency at the call site instead of injecting it through the constructor. | ||

| Hypervel's Eloquent `Model` implements `Transient`, so resolving an application model through the container always returns a fresh model. Query hydration and Eloquent's shared model metadata caches use their existing optimized paths. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Qualify the Eloquent freshness claim.
Line 771 states that explicit singleton(), scoped(), bind(), and instance() registrations retain precedence. Therefore, an explicitly singleton-bound or instance-bound model is not always fresh. Change this sentence to say that unbound application model resolutions are fresh.

model resolutions, while preserving the documented precedence of explicit

Clarify that Eloquent models receive fresh unbound resolutions while explicit container registrations remain free to select singleton, scoped, bound, or instance lifetimes. This aligns the Eloquent example with the precedence rule documented immediately above it without changing container behavior.

Problem
Hypervel auto-singletons unbound concrete classes for the worker lifetime. That is the correct default for stateless services, but Eloquent models are mutable objects.
Three routing paths resolve model classes through the container:
ResolvesRouteDependenciesRouteBinding::forModelThe resolved model was cached and reused by later requests handled by the same worker. Custom route-binding state could leak between requests. More seriously, a controller-injected model could retain attributes and
exists = true, allowing a later request that intended to insert a row to update the previous request's row instead.Change
This adds
Hypervel\Contracts\Container\Transient, an inherited marker for class hierarchies whose unbound resolutions must always be fresh.The container excludes transient concrete classes from:
Eloquent's base
Modelimplements the marker, so every application model inherits the correct lifetime. The fix applies at the container boundary and covers all current and future container-based model resolution paths without routing-specific construction rules.Explicit
singleton,scoped,bind, andinstanceregistrations remain authoritative. Lifecycle attributes, aliases, extenders, resolving callbacks, and parameterized resolutions also retain their existing behavior.Design
Transientdeclares lifetime without changing construction. This keeps it separate fromSelfBuilding, which lets a class control construction throughnewInstance().An interface is used because application models inherit it from
Model; PHP class attributes do not provide that inheritance rule. There is no model registry, class-name check, route-level workaround, lifetime graph, or new cache.A transient dependency captured by a longer-lived consumer still follows the consumer's lifetime. The container documentation calls out this standard captive-dependency rule rather than adding lifetime propagation machinery.
Performance
Unbound stateless services keep the existing auto-singleton fast path. Normal Eloquent queries and hydration continue to use
newInstance()andnewFromBuilder()and do not resolve each model through the container.The extra interface check occurs only while resolving an uncached, unbound concrete. Transient classes then pay only the construction cost their lifetime requires. No worker-lifetime metadata or request cleanup is added.
Compatibility
This restores fresh model receiver behavior consistent with Laravel while preserving Hypervel's performance-oriented container defaults. Existing container APIs and explicit lifetime choices are unchanged. The new marker is an additional Hypervel API for mutable class hierarchies that need the same behavior.
The container documentation and Laravel porting guide now describe the lifecycle, Eloquent's default, explicit-registration precedence, and captive dependencies.
