shard(tick): 2026-05-16T13:10Z — root-caused PR #3871 blockers (rebase + MD032)#3879

… scaffold shipped 2026-05-10) Audit-triage retry. First close-row attempt (tick 10:27Z) aborted mid-flight due to peer-Otto session-close branch churn during two-step Edit. Single-shot Bash sed/heredoc avoids the multi-Edit-tool window. Class #1 (pure drift): - docs/substrate-shelves/mystery-schools-mithraic.md (435 lines, 141 domain-term mentions) shipped 2026-05-10 — frontmatter date matches row's filed date - Stage-1 deliverable fully present per acceptance criteria - Row's status: open was never updated to closed Close + Resolution section append + BACKLOG.md regen.

…e + MD032) Investigation discipline applied per blocked-green-ci rule: PR #3871 stale since 12:15Z because branch was forked off main BEFORE PR #3870 merged the referenced memory file. Plus MD032 markdownlint failure on line 101 (`+ this tick's...` parsed as list bullet, needs blank line before). Server-side rebase via `gh pr update-branch --rebase 3871` failed twice with transient GraphQL errors. Local-rebase path deferred under Lior-active contention (3 procs).

Pull request overview
Investigation-only tick shard that root-causes the two CI checks blocking PR #3871 (a stale rebase plus an MD032 list-bullet parse on a + line in the 1207Z shard), records a failed server-side rebase attempt, and — separately — closes backlog row B-0049.2 after discovering its Stage-1 Mithraic shelf already shipped (drift class #1).
Changes:
- Add new tick-history shard
docs/hygiene-history/ticks/2026/05/16/1310Z.mddocumenting PR #3871 root-cause + deferred fix path. - Mark backlog row B-0049.2 closed and append a "Resolution" section explaining the substrate-drift discovery and second-attempt close.
- Reflect B-0049.2 closure in the generated
docs/BACKLOG.mdindex.
