tine diff

Compare two portable v2 artifacts by graph lineage. The command aligns lineage positions and reports added, removed, and changed steps.

tine diff failed.tine retry.tine

Field-level changes

Changed steps render before-and-after deltas for inputs, outputs, errors, model or tool metadata, and recorded usage or cost. Cost and usage drift can be visible even when the logical step identity is otherwise aligned.

Debugging loop

tine show failed.tine
tine fork failed.tine --from-step 3 --save retry.tine
tine diff failed.tine retry.tine

The common ancestor explains what both runs shared; the field deltas explain the intervention.

Repository semantic diff

V3 repository diff is a separate Python and MCP operation. It compares immutable event graphs and aggregates tool path, usage, billing, latency, artifacts, and evaluation scores. It does not line-merge transcripts. See repository v3.
