feat(run): hint when /tmp artifact I/O is filtered out of lineage#130
Merged
Conversation
filters.ignore_tmp_files (on by default) drops /tmp reads/writes, so a run in a /tmp workspace silently records no artifacts — a common surprise. Surface the existing filtered-/tmp count as an amber hint after the run summary, gated like next_steps_hint (quiet + hints.enabled). Reuses the count the filter already computes; no extra recording.

Why
filters.ignore_tmp_filesis on by default, so aroar runwhose workspace lives under/tmpsilently records no artifacts (its reads/writes are filtered). This is a common, confusing surprise — you getin:0 out:0with no explanation unless you happen to run-vv.What
After the run summary, emit an amber
hint:whenever at least one/tmppath was filtered:result.filter_counts["tmp_files"]) — no extra recording, no added tracer overhead.next_steps_hint: suppressed by quiet mode andhints.enabled = false; goes to stderr.roar runexecution path and the legacyshow_report.Tests
5 new cases in
tests/unit/test_run_report.py: fires when tmp filtered (plural + singular), silent when nothing filtered / key absent, silent in quiet mode, silent when hints disabled. Fulltest_run_report.pygreen; ruff check + format clean.🤖 Generated with Claude Code
