+# PR #3680: fix(hygiene): 5→6 .. for repo-root paths in 0213Z tick shard
+
+## PR description
+
+Same Copilot P1 pattern flagged on [PR #3676](https://github.com/Lucent-Financial-Group/Zeta/pull/3676) (0210Z shard): tick shards live 5 directories below `docs/`, so `../../../../../` lands at `docs/` not repo root.
+
+[PR #3679](https://github.com/Lucent-Financial-Group/Zeta/pull/3679) merged at 02:19:07Z before review caught the issue → fixing on main.
+
+Diff: 2 broken links (1 `.claude/rules/...`, 1 `docs/backlog/...`) → correct 6-level form.

+## Pull request overview
+
+Fixes two broken relative links in the `0213Z.md` tick shard. The file lives 6 directories below the repo root (`docs/hygiene-history/ticks/2026/05/16/`), so paths needed `../../../../../../` (six `..`) rather than the original five to reach repo root before descending into `docs/backlog/...` and `.claude/rules/...`. Same xref-integrity pattern previously flagged on PR #3676.
+
+**Changes:**
+- Corrects `..` depth from 5 to 6 on the `B-0545` backlog row link.
+- Corrects `..` depth from 5 to 6 on the `.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md` link.
