    "core_distinction": "The separation between **individual memory operations** (each write, read, or update is correct) and **collective memory integrity** (the accumulated memory remains coherent and usable over time). Relying on individual operations creates the **Collective Entropy Accumulation**: every operation is locally correct, but their aggregate produces a memory that is...",
    "what_was_observed": "In long-lived collective agent memory, failing to prevent entropy produces three primary failure modes: 1. **Format Divergence:** Early entries use format A, later entries use format B, and there is no unified schema. Readers must handle multiple formats, and eventually the read logic becomes intractable. 2. **Semantic Drift:** Terms used in early entries have different meanings than the same terms used later. A sing...",
    "condition_of_validity": "* **Applies when:** Collective memory accumulates over long timescales, individual operations are correct but can produce aggregate disorder, and usability depends on coherence. * **Does not apply when:** Collective memory is strictly normalized at every operation, or memory is discarded quickly enough that entropy cannot accumulate.",
    "decision_boundary": "1. **Is the collective memory accumulating over long timescales?** If no, standard memory management applies. If yes, proceed. 2. **Is `collective_memory_entropy_metric_receipt` being computed?** If yes, entropy accumulation is visible. If no, the collective is entropy-blind. 3. **Does the entropy metric exceed `entropy_threshold_signature`?** If yes, normal...",
    "operational_effect": "1. **Format Consistency:** Canonical forms are enforced, preventing format divergence. 2. **Semantic Stability:** Terminology is normalized, preventing ambiguity. 3. **Redundancy Control:** Periodic deduplication prevents redundancy explosion."
