"""Door C's own outcome is a bundle the reading direction can open.

vegnormal-okf, 2026-09-08 (FUNN 1): `import_bundle` wrote the root index with
no frontmatter and took no `root_frontmatter_values`, so it could not declare
`bundle_id`. `okf consume` then refused the result with exit 1,
`bundle_id_missing` -- section 3.1's identity tuple is `(bundle_id,
concept_id)` and half of it was absent. The consumer's workaround was to use
Door C as a GATE and write the consumable tree themselves.

The fix is the mechanism Door B already has and Door C did not: a profile
names a key, the CALLER owns its value (decision E1). It is keyword-only with
a default of `None`, so every existing call site emits the bytes it always did
-- a consumer with branch bases built through this door is not asked to
rebuild them, which is the boundary this repository states for its own
consumers.
