- Around line 93-97: In the HumanTasksTab render path, derive an activeArtifact
from selectedArtifact and the current artifacts list, falling back to the first
artifact or null when the selection is absent. Use activeArtifact for artifact
tab isActive state and ArtifactFilePreview’s path while retaining the existing
synchronization effect, and add a rerender test confirming removed artifacts are
never passed to the preview.

Persist safe artifact-relative references with the human-task snapshot so operators can preview current-run review context without changing task lifecycle semantics. Closes dagucloud#2798

Compare
humanTaskActionConfig sets additionalProperties to false and declared only prompt and form, so every workflow using with.artifacts was reported invalid by the Web UI DAG editor and by any IDE consuming the published schema. Runtime was unaffected because the schema is served rather than enforced. Path rules stay in internal/spec. The schema validator uses RE2, which cannot express "no parent-directory segment" without lookahead, and the existing artifactActionConfig.path precedent is an unconstrained string.
with.artifacts was stored verbatim and never resolved, so an authored
${params.OUT}/report.html reached the Web UI as literal text and
produced a silent 404 in the preview. Spec 003 already resolves
steps[].with by default, and with.prompt on the same step resolves when
the task opens, so the literal-only carve-out was the anomaly.
Artifact paths now resolve alongside the prompt. A reference can add
path segments the authored literal never had, so each resolved value is
re-checked against the artifact-relative path rules and an unsafe result
fails the step without opening it. Entries that resolve to the same path
contribute one reference.
dagu status now lists the resolved paths, which the CLI never showed.
activeArtifact already falls back to the first path when the selection is absent or no longer present, so the effect that mirrored that logic into state only cost an extra render on every run-data refresh. Label the artifact tab list through ts(), matching the artifacts tab, which labels the same component that way.
Resolves reference_fields_test.go, where main and this branch each appended a test after the shared path-set fixture. Both are kept.
Artifact paths became runtime-resolved text in this branch, so a path
like reports/${DEPLOY_TOKEN}.html now persists the secret into run
status, returns it from the run-details API, and prints it via dagu
status. maskStepSecrets masked the prompt but not the artifact list, so
the same secret was hidden in one field and exposed in the other.
Artifact path safety is enforced twice: once on authored values in internal/spec and once on runtime-resolved values in internal/runtime. Nothing asserted the two agreed, and the one real divergence, the empty-path message, was masked by a substring assertion. Both packages now run the same table, so drift surfaces as a diff between two otherwise byte-identical cases.
A human task may reference artifacts in a run that stores none, and nothing objects at build or run time. The preview then requested a missing file and rendered the raw server string, "artifact directory not found for dag-run <id>", in destructive red beside a Download button that would also fail. The artifacts tab shows a muted explanation in the same situation; match it. Give the artifact tabs role=tablist and role=tab with aria-selected, matching the six other Tabs call sites that already do, and register the two new strings for Chinese and Japanese.
State that with.artifacts references artifacts produced elsewhere in the run and does not enable artifact storage, so the asymmetry with the artifact.* actions of Spec 051 reads as intent rather than an omission. Cover the rule that a missing referenced artifact leaves completion untouched; the fixture already references files the run never writes, so completing the task proves it. The build-time test claimed references survive verbatim, which the neighbouring test disproves: the build normalizes separators. Assert the property that actually holds, that references are not resolved, with a fixture that is not a path.Clean fixed point.

Included review availability: Your plan provides up to 8 included reviews per hour; 7 remain after this review.
The editor schema accepted absolute and parent-directory artifact paths that the parser rejects, so an author saw the error only at validate time. A "not" pattern closes the gap; the file already uses that form in 53 other places. The pattern is a second encoding of cleanStepArtifactPath in another language, so a test drives both from one table and fails if they ever disagree.
