Module config 

Tunable parameters for the replication subsystem.

All values below are a reference profile used for logic validation. Parameter safety constraints (Section 4):

1. 1 <= QUORUM_THRESHOLD <= CLOSE_GROUP_SIZE
2. Effective paid-list threshold is per-key dynamic: ConfirmNeeded(K) = floor(PaidGroupSize(K)/2)+1
3. If constraints are violated at runtime reconfiguration, node MUST reject the config.

Structs

ReplicationConfig

Runtime-configurable replication parameters.

Constants

AUDIT_FAILURE_TRUST_WEIGHT

Trust event weight for confirmed audit failures.

AUDIT_ON_GOSSIP_COOLDOWN_SECS

Per-peer cooldown between gossip-triggered subtree audits (ADR-0002), in seconds. Bounds how often any one peer is audited regardless of gossip rate.

AUDIT_ON_GOSSIP_PROBABILITY

Probability of launching a subtree audit when a peer’s changed commitment is ingested via gossip (ADR-0002). Keeps audits occasional surprise exams.

AUDIT_SPOTCHECK_COUNT

Number of subtree leaves spot-checked against real chunk bytes per audit (ADR-0002 real-bytes layer).

AUDIT_TICK_INTERVAL_MAX

Audit scheduler cadence range (max).

AUDIT_TICK_INTERVAL_MIN

Audit scheduler cadence range (min).

BOOTSTRAP_CLAIM_GRACE_PERIOD

Maximum duration a peer may claim bootstrap status before penalties apply.

FETCH_REQUEST_TIMEOUT

Fetch request timeout.

FRESH_REPLICATION_DELIVERY_MAX_RETRIES

Best-effort delivery retries for a fresh-replication push, per peer.

K_BUCKET_SIZE

Maximum number of peers per k-bucket in the Kademlia routing table.

MAX_AUDIT_RESPONSES_PER_PEER

Maximum concurrent in-flight audit-responder tasks from any SINGLE peer.

MAX_BYTE_CHALLENGE_KEYS

Maximum keys per round-2 SubtreeByteChallenge (per-batch cap).

MAX_CONCURRENT_AUDIT_RESPONSES

Maximum number of concurrent in-flight audit-responder tasks.

MAX_CONCURRENT_REPLICATION_SENDS

Maximum number of concurrent outbound replication sends.

MAX_PRUNE_AUDIT_CHALLENGES_PER_PASS

Maximum number of prune-confirmation audit challenges sent per prune pass.

MAX_REPLICATION_MESSAGE_SIZE

Maximum replication wire message size.

NEIGHBOR_SYNC_COOLDOWN

Per-peer minimum spacing between successive syncs with the same peer.

NEIGHBOR_SYNC_INTERVAL_MAX

Neighbor sync cadence range (max).

NEIGHBOR_SYNC_INTERVAL_MIN

Neighbor sync cadence range (min).

NEIGHBOR_SYNC_PEER_COUNT

Number of close-neighbor peers synced concurrently per round-robin repair round.

NEIGHBOR_SYNC_SCOPE

Number of closest peers to self eligible for neighbor sync.

PAID_LIST_CLOSE_GROUP_SIZE

Maximum number of closest nodes tracking paid status for a key.

PENDING_VERIFY_MAX_AGE

Maximum age for pending-verification entries before stale eviction.

POSSESSION_CHECK_DELAY_MAX

Upper bound of the possession-check delay (ADR-0003).

POSSESSION_CHECK_DELAY_MIN

Lower bound of the delay before a fresh-replication possession check runs (ADR-0003).

PRUNE_HYSTERESIS_DURATION

Minimum continuous out-of-range duration before pruning a key.

QUORUM_THRESHOLD

Full-network target for required positive presence votes.

REPAIR_HINT_MIN_AGE

Minimum age for a replica repair hint before the hinted peer can be audited for that key.

REPLICATION_PROTOCOL_ID

Protocol identifier for replication operations.

SELF_LOOKUP_INTERVAL_MAX

Periodic self-lookup cadence range (max).

SELF_LOOKUP_INTERVAL_MIN

Periodic self-lookup cadence range (min) to keep close neighborhood current.

STORAGE_ADMISSION_MARGIN

Extra local-routing-table positions accepted for local chunk storage admission and stored-record pruning.

SUBTREE_AUDIT_TIMEOUT_LEAF_HINT

Conservative leaf-count hint for sizing the subtree-audit response deadline.

VERIFICATION_REQUEST_TIMEOUT

Verification request timeout (per-batch).

Functions

max_parallel_fetch

Returns the number of hardware threads available, used as the fetch concurrency limit.

storage_admission_width

Width used when deciding whether this node may locally store or retain a chunk.
