Package advertise reconciles the local containerd content store against the set of digests this node is advertising on the DHT.

Package cdsub subscribes to containerd image/content events and forwards digest presence changes to its caller.

Package coldstart implements the / the design doc rule cascade that decides how an agent resolves a digest when its local cache misses and the DHT lookup did not return enough providers.

Package config is the single source of truth for every operator-tunable knob the Gantry agent exposes.

Package containerdstore adapts a containerd content store to the gantry ifaces.LocalContentStore contract so the rest of the agent can read from and write into containerd as the single local source of truth for image content.

Package coord implements Gantry's libp2p coordination RPCs.

Package digest defines the canonical OCI digest type used across Gantry.

Package digestpipe is the digest-verifying stream tee.

Package discovery wires Gantry's libp2p host and Kademlia DHT.

Package hrw implements Rendezvous (Highest-Random-Weight) hashing for Gantry's per-digest puller selection (the step 3).

Package ifaces declares the cross-cutting interfaces that Gantry's subsystems implement and depend on.

Package fakes provides in-memory implementations of the ifaces interfaces for unit and integration tests.

Package inflight tracks per-digest pulls currently being executed on this agent.

Package log is the structured-logging entry point for Gantry.

Package manifest parses OCI v1 / Docker v2 schema-2 image manifests just enough to extract the layer and config digests they reference.

Package members - self-announce: write this agent's libp2p peer.ID, multiaddrs and transfer endpoint into its own Pod's annotations so other agents can discover the libp2p identity without operator-supplied bootstrap config.

Package metrics owns the Prometheus registry shared across Gantry subsystems and provides constructor helpers that record metric ownership so final audit can verify the metric set is complete.

Package mirror is the loopback OCI registry mirror containerd talks to via hosts.toml .

Package negcache implements the per-puller, in-memory negative cache described in the design doc of the Gantry design.

Package oci hosts shared OCI/Distribution-spec helpers used by more than one Gantry subsystem.

Package origin pulls bytes from upstream OCI registries.

Package transfer is the peer-facing OCI endpoint other Gantry agents pull from.

Package allocator provides CIDR allocation functionality for Kubernetes nodes.

Package certmanager manages TLS serving certificates for the controller using a self-signed CA.

Package config provides configuration types for the unbounded-net-controller.

Package controller implements the Kubernetes node controller for CIDR allocation.

Package ebpf provides eBPF-based tunnel dataplane management.

Package html embeds HTML page templates used by the controller and node binaries.

Package metrics provides shared Prometheus metrics helpers for the unbounded-net controller and node agent.

Package netlink provides utilities for managing network configuration using netlink

Package app wires the Orca runtime: origin + cachestore + cluster + fetch coordinator + edge / internal HTTP listeners.

Package cachestore defines the in-DC chunk store interface and shared types.

Package s3 is the cachestore driver for in-DC S3-compatible stores.

Package chunk implements the chunk model: ChunkKey, deterministic path encoding, and the range -> chunk-index iterator.

Package chunkcatalog implements a bounded LRU recording chunks known to be present in the CacheStore.

Package cluster handles peer discovery and rendezvous-hash coordinator selection.

Package config defines Orca's YAML configuration shape and loading helpers.

Package fetch is the per-replica fill orchestrator: per-ChunkKey singleflight, pre-header origin retry, per-replica origin concurrency cap, and cross-replica fill via the cluster's internal RPC.

Package manifests holds tests that validate the orca deployment manifest templates render to syntactically correct, structurally reasonable Kubernetes YAML.

Package metadata is the per-replica object-metadata cache.

Package origin defines the upstream-blob-store interface and shared types.

Package awss3 is the AWS S3 (and S3-compatible) origin driver.

Package azureblob is the Azure Blob Storage adapter for the Origin interface.

Package server holds the HTTP handlers for the client edge and the internal-listener.
