Protocol learning artifacts are maintained by generating per-cycle cdd-iteration.md files during close-out and appending entries to a central INDEX.md, preserving auditability across handoff, cdd, and epsilon roles.

The canonical INDEX.md format for cross-cycle aggregation uses an eight-column structure that records each cycle artifact, enforcing cross-repo bundle and archival invariants to surface patterns across iterations.

Cycle close-out with protocol_gap_count greater than zero is handled by enforcing the canonical per-finding shape inside cdd-iteration.md, while optionally writing courtesy stubs for clean cycles to maintain learning signals.

Per-cycle iteration artifacts are needed during gamma-closeouts and epsilon reviews to guarantee alignment between cycle close-outs, artifacts, and their cross-repo traces, ensuring a durable and auditable learning signal.

Cycle close-out enforces cross-repo bundle and archival invariants by producing per-cycle cdd-iteration artifacts and updating the persistent cross-cycle index, ensuring traces remain aligned and auditable across repositories.

Cross-cycle learning signal updates are automated by writing structured cdd-iteration.md files during cycle close-out and appending rows to .cdd/iterations/INDEX.md, enforcing the canonical eight-column format automatically.
