Task: Implement Close the sprint's finished stories

Close every sprint story whose tasks are all DONE, record what finished each one, and correct the one sentence in the role-request journey that contradicts its own gap table.

• A scan reports no story STARTED with all tasks DONE.
• Each closed story has a Result that says what finished it.
• The journey's prose agrees with its table.

The twelve were found by scanning every sprint_27 story for a STARTED state whose task files are all DONE. Each was closed with compass story done, which flips the story, its sprint row and the journal together. The Results were appended afterwards: the seven hotfixes from their merged PR numbers, read out of the task files, and the five larger stories with a sentence saying the close records task state rather than a fresh verification.

The journey sentence was one line: it said six of the seven gaps were closed and one half closed, where the table beneath it marks all seven closed and the two sweeps that answered the seventh are described further down the same page.

The five larger stories were closed on their tasks' state. Their tasks are DONE with merged PRs and written Results, so the work has finished by every record the sprint holds; what is missing is the owner's own close. The Results say so, so a reader is not misled into thinking somebody re-verified the goals.

Twelve stories closed, eleven Results written, one journey sentence corrected. No code changed.
