ADDED Requirements

Requirement: Process-Level Cache SHALL Use Bounded Capacity with Deterministic Eviction

Process-level parsed-data caches MUST enforce a configurable maximum key capacity and use deterministic eviction behavior when capacity is exceeded.

Scenario: Cache capacity reached

• WHEN a new cache entry is inserted and key capacity is at limit
• THEN cache MUST evict entries according to defined policy before storing the new key

Scenario: Repeated access updates recency

• WHEN an existing cache key is read or overwritten
• THEN eviction order MUST reflect recency semantics so hot keys are retained preferentially
