No good reason to filter this in the execArtifact container, and the extended filter breaks certain programs.

internal/pkg: cache computed identifiers2026-01-15T14:30:43ZOphestracat@gensokyo.uk2026-01-15T13:05:24Zurn:sha1:3499a82785f8cb82bfe528875391d76d5e03c3de
This eliminates duplicate identifier computations. The new implementation also significantly reduces allocations while computing identifier for a large dependency tree.

internal/pkg: exec prefix verbose output2026-01-12T13:15:01ZOphestracat@gensokyo.uk2026-01-12T13:15:01Zurn:sha1:5fe166a4a74339440647b09d416c5d0784a6c3ee
This proxies program output through msg with a name and fd prefix. This also avoids introducing additional information to the container via process stdout/stderr.

internal/pkg: caller-supplied reporting name for exec2026-01-11T19:17:47ZOphestracat@gensokyo.uk2026-01-11T19:17:47Zurn:sha1:29951c51749f1c3f5ca96488bff6eee247c03dc7
This does not have a reasonable way of inferring the underlying name. For zero value it falls back to base of executable pathname.

internal/pkg: move dependency flooding to cache2026-01-08T20:20:34ZOphestracat@gensokyo.uk2026-01-08T16:51:39Zurn:sha1:f7124667145d1f7c614d9fc644bc07bb6174454a
This imposes a hard upper limit to concurrency during dependency satisfaction and moves all dependency-related code out of individual implementations of Artifact. This change also includes ctx and msg as part of Cache.
