(1) PR #809 (tick 06:13Z fix shard) and PR #810 (tick 06:16Z thread-triage shard) both squash-merged onto main. (2) PR #810 had been BLOCKED with all-green CI per Otto-355 — investigated thread first: Copilot's claim was "row must start at column 0 with single leading `\|` (no `1 \|\|` prefix)" but `git show ... \| od -c` confirmed actual file starts with `\|` at column 0. Classified as DISPLAY_ARTIFACT per the just-landed B-0101 taxonomy. Resolved with explanatory comment. | [#809 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/809), [#810 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/810), [#811 CI in-progress](https://github.com/Lucent-Financial-Group/Zeta/pull/811), [#812 CI in-progress](https://github.com/Lucent-Financial-Group/Zeta/pull/812) | Second operational use of B-0101 taxonomy in two ticks — DISPLAY_ARTIFACT bucket fired again on the same `\|\|` hallucination class Copilot has produced in PR #792 + PR #806. Three confirmed instances now make this Copilot's most reliable false-positive class. The mechanical guard candidate: a one-shot script that does `git show : \| od -c \| head` against any review comment quoting leading-pipe pathology — auto-resolves the thread with the hexdump as evidence. Worth filing as a follow-up backlog row alongside B-0098/B-0099/B-0100/B-0101 if the pattern continues. The convergence holds: each tick produces 1-2 merges + 0-1 reviewer-artifact triage + 0-1 substrate. |
