Command substitution strips every trailing newline, so 'grouped\n\n'
reached the case as a clean word and passed — the round's shared blocker
(codex, grok). A line count taken from the file itself now refuses any
physically multi-line sentinel before the word check runs, with the
existing diagnosis naming the file. Red rows: grouped/flat with a
trailing blank line in the unit suite, grouped in the armed suite.

The sentinel pins the set's shape, outranking the newest-published-section
inference (#182 D2); malformed content is a red diagnosis naming the file.
bin/changelog-assemble skips 'shape' in the stray-file loop so the sentinel
survives the consumption (#182 D5).

One definition in the fragment predicate; changelog-armed reds the PR
that writes the fragment and the assembler refuses at release, both by
inheritance. Doctrine names the number in BUILDER.md and CHANGELOG.md.

lib/changelog.sh gains changelog_fragments (publication order: trailing
issue number descending, filename tie-break), changelog_fragment_problem
(the release-time rules moved onto the PR that writes the fragment, #112
D9), and changelog_assemble (canonical group order per D5, one shape per
repo per D4). bin/changelog-assemble folds changelog.d/ into one release
section, deletes exactly what it consumed, and --check proves the body
without touching the tree.
Part of #112. Closes#114 groundwork; tests follow.
