+## Step 4a — PR #3086 MD056 table-column-count fix
+
+Markdownlint reported line 28 of the 0141Z shard had 5 cells where the
+table declared 3. Root cause: cell text contained literal pipe
+characters inside code spans (`` `||` ``, `` `grep -n '\|\|'` ``);
+markdownlint's table parser counts ALL `|` chars as column separators,
+ignoring backtick escapes.
+
+Rewrote the cell as prose ("double-pipe", "`grep` for the pattern")
+instead of code-spanning the literal characters. Commit fe5f3ad on the
+branch.
+
+This is the third markdownlint failure-mode in three consecutive
+tick-shard PRs:
+
+1. PR #3080: MD032 (line wrap puts plus-space at line-start, parsed as list)
+2. PR #3084: MD038 (backtick + space + backtick = space inside code span)
+3. PR #3086: MD056 (literal pipes in code spans counted as table cells)
+
+Each is a distinct rule but the underlying pattern is the same:
+markdownlint's parser is more literal than CommonMark suggests, so prose
+that *looks* like a code-span describing a markdown construct often *is*
+treated as that markdown construct.
+
+## Step 4b — PR #3075 cleared all threads
+
+`gh api graphql` reports 30 total threads on PR #3075, 0 unresolved,
+0 outdated-unresolved. `mergeable: MERGEABLE`. Auto-merge armed. The
+DIRTY state from prior ticks resolved (concurrent ticks completed
+rebase + cleanup).
+
+PR #3075 (B-0456 MD032 helper) is now waiting only on CI re-run before
+auto-merge. The helper, once merged, will catch the exact failure mode
+that's been recurring across my session's shard PRs.

+Sentinel `81c5e1a9` firing every minute.
+
+## Visibility signal
+
+Three iterations into the recurring markdownlint-fix cycle, each pass
+addresses one rule then surfaces a smaller variant of the same root
+cause (markdownlint parser is literal). The B-0456 helper (PR #3075)
+once landed should at minimum catch the MD032 variant; the MD038 and
+MD056 variants would still slip through but become catchable as future
+helper extensions.
+
+Loop continues.
