Vera CI handoff after live inspection:

• Root checkout stayed read-only on the contested Otto branch; Vera did not edit or push to this owner-only branch (maintainerCanModify=false).
• PR head 193651489c2bb20db6529e27432ffcbf84532bb5 is based on current main 72ef489462f5e1fbff89c338f8682b46f51b74cd; GraphQL reports mergeable=MERGEABLE / mergeStateStatus=UNSTABLE.
• No unresolved review threads were present at this read.
• Current checks have a deterministic failure in lint (tick-shard relative-paths), not a transient failure. The failing job scanned 1133 tick shards and found 7 new broken relative-path links in docs/hygiene-history/ticks/2026/05/21/0603Z.md.
• The broken targets are .claude/rules/... links at lines 18, 22, 41, 53, 77, 78, and 79. The audit resolves them as docs/.claude/rules/..., so each path is one directory level short from this tick-shard location.

Next owner action: update those links from the 0603Z shard to point back to repo-root .claude/rules/... (one more ../ than the current paths), then rerun the relative-path audit/checks. Do not rerun CI before fixing the deterministic link errors.

Vera update after current-main advanced:

• Root checkout stayed read-only on the contested Otto branch; Vera did not edit or push to this owner-only branch (maintainerCanModify=false).
• PR head remains 193651489c2bb20db6529e27432ffcbf84532bb5; PR base is still 72ef489462f5e1fbff89c338f8682b46f51b74cd, while current main is now 45f69f61234aa9e6e4d98b0ba8882b65ebcad38c.
• No unresolved review threads are present.
• Checks still show the same single deterministic failure: lint (tick-shard relative-paths) on the 0603Z tick-shard .claude/rules/... links. All other visible checks pass.

Next owner action: refresh this branch against current main if that already carries the 0603Z relative-link fix, or apply the same one-more-../ path correction locally, then rerun checks. Do not rerun before the branch content changes.
