decdn bundle pull — fetch a bundle’s blobs into a directory.

The bundle source is exactly one of -i <file> (a local manifest) or --hash <b3> (fetch the manifest blob first, then its entries). Both then run the same per-entry fetch loop. The network/chain/target flags come from the flattened ClientFetchArgs — --node-id pins every entry to one node, --channel-id (#1481) adopts one publisher-opened channel and pins the whole bundle to its provider, otherwise each entry is discovered independently (#936/#391). --namespace (ADR 002) routes every cache-miss origin pull to a namespace’s authorized origins.

Fields

input: Option<PathBuf>

Local bundle manifest file to pull. Mutually exclusive with --hash.

hash: Option<String>

BLAKE3 hash (64 hex, optional 0x/b3: prefix) of the bundle manifest blob to fetch first, then pull. Mutually exclusive with -i.

output: PathBuf

Output directory the bundle’s files are written under (created if absent). Each entry’s relative path is resolved within this root; ../absolute/escaping paths are rejected.

jobs: usize

Maximum concurrent entry fetches across the whole run. Each distinct blob is one unit of work holding one slot: a plain whole-file entry, or a range-dedup entry across its complement drive, donor splice, and any re-fetch. A range-dedup entry that only waits for a sibling to finish the chunks it splices gives its slot to a queued entry until then. A byte range a sibling entry already holds is spliced from disk, not fetched, so it never takes a slot of its own.

max_lane_streams: u16

Maximum concurrent streams to one (pool, signer, provider) lane. Same-lane streams share one cumulative voucher watermark, and the serving node credits each stream’s delivered bytes from that shared lane fairly (a slow stream is paid from the headroom a faster sibling opened), so same-lane concurrency is safe and this only bounds how many streams touch one provider at once. Cross-lane parallelism (distinct providers) is bounded by --jobs regardless.

One connection per node carries every stream of the command, so the bound (1 to 64) stays below the node’s limit of concurrent streams on one connection.

include: Vec<String>

Only pull entries whose POSIX relative path matches one of these globs (models/*.bin), matched against the manifest’s path field, never the on-disk absolute path. Repeatable — an entry passes the include gate if it matches any one. Absent => every entry passes the gate. gitignore semantics: * does not cross /, ** recurses.

exclude: Vec<String>

Skip entries whose POSIX relative path matches one of these globs, matched against the manifest’s path field. Repeatable — every pattern is OR-ed. --exclude wins over --include: an entry matching both is skipped. Same gitignore glob semantics as --include.

select: bool

Choose which files to pull interactively: open the (post---include/ --exclude) file list in $VISUAL/$EDITOR, one path per line. Comment out (prefix #) or delete any line to skip that file; save and exit to pull the rest. Useful when you don’t know a bundle’s contents up front — the list is what the manifest actually holds. Requires an interactive terminal; incompatible with --json and --dry-run.

overwrite: bool

Re-fetch and overwrite entries whose destination file already exists. Default is skip-existing (resume-friendly): a path skips when its saved .decdn-manifest.json record still matches the file’s hash, size, and mtime — the fast path, which trusts that gate without re-hashing — or, failing that, when re-hashing its on-disk bytes matches the new manifest. A file byte-identical to one already anywhere else in the output root is likewise reused with no download: it is linked (or copied) from that on-disk file once its hash is confirmed by a re-hash. Use --overwrite to force a full re-fetch of every entry, for example when the output directory may have been modified outside decdn (an in-place edit that keeps a file’s size and mtime is otherwise trusted by the fast path). It skips consulting .decdn-manifest.json for skip decisions, so it disables both the skip-existing path and the whole-root reuse above; the file is still read and rewritten with the run’s results.

dry_run: bool

Print the entries the run would pull (paths + sizes, after --include/--exclude; files already present are still listed) and exit without any network or chain activity. With --hash, entries are listed only when an earlier pull into the same output directory cached the bundle manifest.

json: bool

Emit a one-line JSON summary instead of human-readable output.

namespace: Option<u64>

Namespace the whole bundle is published under (ADR 002 § Retrieval by namespace). Applies to EVERY fetch in the run — the manifest blob and each entry — so a serving node routes any cache-miss origin pull to that namespace’s DAO-authorized origins. The manifest format carries no per-entry namespace, so this is necessarily bundle-level. Absent => no namespace: served best-effort from cache / DHT only.

common: ClientFetchArgs

Retrieval flags shared with decdn fetch: peer discovery, payment pool, and output handling.
