-- [ ] t149 feat: auto-create GitHub issues when supervisor adds tasks #enhancement #supervisor #sync ~2h (ai:1.5h test:30m) logged:2026-02-07 ref:GH#455
-  - Notes: Supervisor creates tasks in SQLite but never creates GitHub issues. Add gh issue create to cmd_add/cmd_batch, update TODO.md with ref:GH#N. Prerequisite for t020/t047 (full bi-directional sync). Immediate need: all dispatched tasks should have GH issue visibility.

   - Notes: Lines 3165 and 3183 of supervisor-helper.sh missing $SUPERVISOR_DB as first arg to db(). Every other db call (20+) passes it. Retry counter never persists. Also remove unused no_pr_key variable on line 3163. From CodeRabbit review on PR #435.

   - Notes: Multiple scripts use BSD sed -i '' syntax. Need portable wrapper in shared-constants.sh. Audit all scripts for sed -i usage. From reviews on PR #406.

   - Notes: tests/test-batch-quality-hardening.sh uses grep '\|' instead of grep -E '|'. Works but ERE is more portable/readable. Also fix imprecise newline check at line 172. Low priority.
