path names a record. A folder-relative `{.name}` or `{..name}` is refused naming
`{/name}`, since an inline template sits in no folder. `IsTemplate` exports the rule, so struct tags and any other caller read one.

Shipped under the floor by the maintainer's decisions of 2026-10-07: the CLI reading its template from stdin, with the scoring run and its ratchet waived for that chunk; and narrowing goal 5.7 to the refusals that catch a mistake, dropping the rest.
Last scoring run, 2026-10-07, on commit ad59967: Navigation 7.00, Locality 5.88, Shape 6.50, Self-sufficiency 6.13, overall 6.38. The nine-seat panel at depth 1, run beside it: Navigation 7.17, Locality 6.06, Shape 6.67, Self-sufficiency 6.56, overall 6.56. Against the runs on ac6158e, the scoring run's overall rose from 6.25 and its Shape from 6.38, while its Self-sufficiency fell from 6.38; the panel's overall held, and its Locality and Self-sufficiency fell by 0.05 each. Locality is lowest again, as at every panel since 2026-09-22. All 13 seats named the named-pick read path hardest: `readField`, `readName`, `readUnder` and `keeps`, with the pick keys `levelKeys` and `addressedKeys` build at load; twelve kept `doc.go`'s vocabulary open beside it. What the two runs found is filed in `todo.md`, and `todo.md` item 153 runs both again. Valid while `AGENTS.md` gates goal 3 at 7.0.
