Skip re-running #[Validate] methods for a semantic-variable value that is carried through a metamorphosis chain unchanged. Measured in the issue at ~12/18 validated args per real chain being exact repeats (~17-18% of chain time spent in validation, ~10% theoretical ceiling reclaimable). Lifecycle (open question #3): the cache is owned by SemanticValidator and gated by an explicit "inside active chain" flag. `$chainCache` is null (inactive) by default; Becoming::__invoke() calls beginChain()/endChain() around the metamorphosis loop in a try/finally, so the cache lives exactly one chain and is always discarded. Every direct caller (validateProps(), validate(), validateLegacy(), validateAndThrow(), validateObject()) leaves the flag off, so caching is fully bypassed and nothing accumulates outside a chain. Hooks are threaded via BecomingArgumentsInterface; NullValidator implements them as no-ops. Key = (parameterName, sort(attributes), valueKey): - scalar/null: gettype().':'.var_export() (no 1/"1"/true collisions) - object: spl_object_id() (safe only under the public-readonly convention, documented at the call site) - array values: never cached - only cached when every resolved #[Validate] method has zero #[Inject] parameters (an injected validator may consult mutable state) Tests pin the two subtle traps and the lifecycle contract: attribute-keyed method selection (validateAge vs #[Teen] validateTeen with the same value), #[Inject]-consuming validators never served from cache, direct calls never accumulating entries, and end-to-end single-validation across chain hops.

Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Chain cleanup and several cache exclusions limit the risk, but the cache treats an object’s identity as proof that its validated contents have not changed. That assumption may not hold for mutable objects passed through a chain; practical exposure depends on application usage. Retained concerns

Exclude resources from value-key generation.
#[Input] values can be resources when the target parameter accepts mixed. The validation resolver selects methods by #[Validate], argument count, and attributes. It does not exclude resources by value type. A matching method that accepts a resource can succeed on the first call and populate the cache. Two same-type resources produce the same var_export() result, so the second validation can be skipped.

Bypass caching for mutable objects.
When validateWithAttributes() receives an object during an active chain, a caller can mutate that object between validations. spl_object_id() remains unchanged, so the second call can hit the existing cache entry and return NullErrors without invoking a validator that would reject the new state. The mixed API does not enforce immutability. The transformation-property readonly convention does not constrain this argument or the referenced object's state.
Return null from chainCacheKey() for objects unless the API enforces deep immutability.

Resolves #81.
Design decision (open question #3: cache lifecycle ownership)
The per-chain cache is owned by
SemanticValidatorand gated by an explicit"inside active chain" flag, implemented as a nullable
$chainCache:null= inactive (default): every call re-validates, nothing accumulates.beginChain()sets it to[](active + fresh);endChain()sets it back tonull.Becoming::__invoke()wraps its metamorphosis loop intry { beginChain() … } finally { endChain() }, so the cache lives exactly one chain and is always torn down — even on exception.BecomingArgumentsInterface(Becoming holds theBecomingArguments, which delegates to its validator).NullValidatorimplements them as no-ops.Every direct entry point —
validateProps(),validate(),validateLegacy(),validateAndThrow(),validateObject()— leaves the flag off, so calling thevalidator outside a chain fully bypasses caching. This closes the
unbounded-growth / stale-result failure mode documented for
SemanticLogger.Cache key & eligibility
Key =
(parameterName, sort($attributes), valueKey):gettype($value) . ':' . var_export($value, true)(avoids1/"1"/truecollisions)spl_object_id($value)— safe only under Be Framework'spublic readonlyconvention (object identity ⇒ unchanged value); documented at the call site#[Validate]method for the variable has zero#[Inject]parameters (an injected validator may consult mutable state and legitimately return a different answer for the same value)Measured economics (from the issue)
