Two small fixes after testing the tool end-to-end:
1. scrum_review.sh's tally-aggregation step occasionally exits non-zero
even when the per-reviewer markdown verdicts are all written
correctly. Wrapper was bailing on that exit code and dropping the
KB write. Now the wrapper:
- Treats scrum_review.sh's exit code as advisory
- If a tally markdown exists, uses it
- If only per-reviewer markdowns exist, auto-rebuilds a minimal
tally listing them (so KB row still gets written)
- Only bails if NO per-reviewer verdicts at all
2. Python `datetime.utcnow()` deprecated. Switched to
`datetime.now(datetime.UTC).isoformat().replace("+00:00", "Z")`
for the same Z-suffix shape callers expect.
Verified: ./scrum --since=HEAD~1 now writes KB row even when
scrum_review.sh's tally step has issues. KB rows: 2 (and growing).
