…play-artifact triage (1) PR #809 + #810 squash-merged. (2) PR #810 BLOCKED-with-green-CI investigated per Otto-355. Copilot thread claimed "leading whitespace / 1 || prefix" but git show + od -c confirmed file starts with | at column 0. Classified as DISPLAY_ARTIFACT per B-0101 taxonomy. Resolved. Third confirmed instance of Copilot's || hallucination class (after PR #792 + PR #806) — most reliable false-positive class. Worth a future automated-resolve script using git show + od -c as evidence. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…#814) + #811 Copilot fixes (#816) (1) PR #812 (0619Z) + #813 (0623Z) + #814 (0625Z) all squash-merged. (2) PR #811 had 2 Copilot threads — both REAL_DEFECT: - B-0098: \b in grep -oE non-portable (POSIX ERE issue); replaced with -w whole-word match. - B-0099: @me placeholder ambiguous; replaced with <gh-login> + clarifying note. Both threads resolved. Merge cascade observation: 3 tick-history PRs landed within seconds once merge-eligibility cleared. Composes with the auto-merge-arm pattern.
