Record the inputs a build read — hf_input

Fingerprints each supplied file, size, modification time and MD5, and optionally writes the result as JSON. Pair it with hf_verify_manifest() to confirm a later run is reading the same inputs.

Hashing streams the whole file, so a multi-gigabyte reference takes a little time. It is worth it once per build rather than per VPU.

Usage

hf_input_manifest(..., out = NULL)

Arguments

...: Named file paths, e.g. reference = "...", fdr = "...", fac = "...". Names become the manifest's roles. NULL entries are dropped.
out: Optional path to write the manifest as JSON. NULL (default) returns it without writing.

Value

A data frame with one row per input: role, path, exists, bytes, mtime, md5.

Examples

f <- tempfile(); writeLines("x", f)
hf_input_manifest(reference = f)
#>        role                             path exists bytes                mtime
#> 1 reference /tmp/RtmpXwoem0/file1fed4dd6525a   TRUE     2 2026-11-12T13:14:57Z
#>                                md5
