-Panels on near-identical code scored overall means of 5.75 to 6.00, and a seat moves ±0.5 between
-runs. The maintainer shipped under a fall twice after three rounds: the move to GitHub, 2026-10-04,
-whose chunk changed only comments in `src/`; and item 78, 2026-10-07, whose three runs fell below
-the run before it on Navigation, Locality and Shape while the overall held. Item 94, 2026-10-10,
-also shipped after three rounds: a definitions-only paragraph leaves no block, so ending the list it
-follows takes state carried across lines, and every design read worse on Locality while the overall
-held; the scores at 6182ba6 were Junior 5.5, Mid 5.5, Senior 6 and Architect 5.5, mean 5.63. Item
-56, still open, is to give that state one owner. Items 85 and 86, 2026-10-11, shipped after three
-rounds under a fall the seats laid on item 93's `splitPath` and `splitPlace`, which placed a refused
-block's path by replaying `splitTaskList` on stand-in nodes until item 102, 2026-10-22, removed them; both seats read the chunk's own image
-builder as a gain. The scores at be23835 were Junior 6.5, Mid 6, Senior 6 and Architect 6, mean
-6.13. Item 106, 2026-10-13, shipped
-after three rounds under a worse ruling, the maintainer's call: both paired seats read the overall
-as the same, but Locality fell to a mean of 5.13, laid on the spelling memo the chunk splits between
-the CommonMark ask, which fills it, and the walk, which drops each entry as it reads it. The overall
-scores at 1f4551a were Junior 5.5, Mid 5.5, Senior 6 and Architect 5.5, mean 5.63.

+A writer reads each escaped line back. Where a code span opens at a text backtick, every text
+backtick in the line escapes, and where a link or an image opens at a text `[`, every text `[`
