 By the maintainer's decision of 2026-10-09, every 0.1.0 chunk ships under the floor, including the chunk that holds the release's scoring run, so that 0.1.0 can ship features. Items 170 to 175 and 177 move to 0.2.0. Item 178 plans first how item 107 regroups the engine. A paired ruling that rules worse still blocks a merge. Valid until 0.1.0 is cut.
 
+Shipped by the maintainer's decision of 2026-10-11 with its ratchet waived: item 182, the shipped data as Go packages, at a632a92. Its last paired ruling against bf1becb was same overall, Mid A better and Junior A worse, with Shape fallen, three seats against the namespace mount in `internal/datafiles/mount.go` and the `at` field of `datafiles.Source`; the scoring run that would rule it worse under the floor was not run. `todo.md` item 197 replaces that mount.

 Shipped under the floor before that by the maintainer's decisions of 2026-10-07, each with the scoring run and its ratchet waived: the CLI reading its template from stdin; and goal 5.7 loading whatever is well-formed and means one thing, dropping every refusal that guessed at a mistake.
 
 The scoring runs are in [the comprehension history](comprehension-history.md). The nine-seat panel at depth 1, run beside the scoring run of 2026-10-09 on commit b9d1af6: Navigation 7.33, Locality 6.17, Shape 6.67, Self-sufficiency 6.83, overall 6.67. Against the panel on ad59967, its overall rose from 6.56, its Navigation from 7.17, its Locality from 6.06 and its Self-sufficiency from 6.56, and its Shape held at 6.67. Locality is lowest again, as at every panel since 2026-09-22. All 13 seats of the two runs found the named-pick keep rule hardest to follow: `keptInPick` and `readUnder`, where a key `pickKey.under` builds at render must equal one `addressedKeys` built at load, with `readField` and `readName` around them. What the two runs found is filed in `todo.md`, and `todo.md` item 177 runs both again. Valid while `AGENTS.md` gates goal 3 at 7.0.

 The maintainer ruled so on 2026-10-09. Today `bindOptions` in `internal/rows` refuses such a table, since `ambiguous`, which reports a name matching several rows, lists those rows by key. Afterwards `ambiguous` lists them by line, the header being line 1, and ends with "make the names unique, or add a key column".

+Item 182 shipped on 2026-10-11 over a paired ruling with Shape fallen, by the maintainer's decision recorded in the comprehension-floor entry. Three seats named the same two costs: `mounted` in `internal/datafiles/mount.go`, a partial `fs.FS` that fakes the folders above a module's namespace and serves only `ReadDir` and `ReadFile`; and `Source.at`, which is at once the mounted flag, the prefix `labelled` strips from error labels and the folder `Manifest` reads from. Tried and ruled down within item 182: doubled folders (`data/sv_SE/sv_SE/`), the mount as a prefix on `Category.Folders` that `Load` strips (two coordinate systems), and a complete `fs.FS` wrapper. Whatever replaces it keeps errors naming files where they are on disk for a data path, and keeps `index.go` unaware of namespaces.

 ### 127. Give a Swedish street only postal codes whose delivery digit means street or rural delivery, dropping codes whose delivery digit is 9, or record why they stay.
 
 `docs/research/research-geo-se.md` reads delivery digit 0 or 1 as boxes, 2–4 and 6–7 as street, 5 as rural, 8 as reply mail and 9 as competitions or temporary, with exceptions in big cities. `street_delivery` drops 0, 1 and 8 and keeps 9. The panel of 2026-10-05 found it; whether a shipped street carries a 9 code is unchecked.
