All three found by the adversarial review of 019cbc1, each by injection.
1. every_model_command() is NOT compiler-maintained, and both this PR's prose
and reduce.rs's own doc comment said it was. variant_name's exhaustive match
forces an arm in variant_name, not an entry in the value list -- deleting
ModelCommand::TogglePruneEmpty from it failed the new completeness check and
NOTHING ELSE in the workspace. So the diff is two independent hand-written
lists: strictly better than one list against its own length, and not the
derived enumeration improvise-5ubs got for the two enums. Doc comment
corrected; the prose in context/code/command.md and the evidence entry now
say what it is. Closing it properly wants improvise_protocol::variants made
pub so declared::<ModelCommand>() can bound the list -- another wave's crate,
reported rather than taken.
The assertion message was also ONE-DIRECTIONAL ("a name only on the right
..."), which is the shape that injection produces and which invites the wrong
repair: delete the case on the left, degrading both sides together. It now
names both directions and says which is which.
2. SELF_TEST_DUPLICATES case 3 was named for the ambiguity guard and never
reached it: both its headings were module-qualified, so canonical() returned
on the exact-match arm before touching by_leaf. Dropping the guard
(`if matches` for `if len(matches) == 1`) left --self-test at exit 0. The
fixture is now one BARE heading over an ambiguous leaf plus BOTH qualified
spellings, so the injection collides with one of them whichever way
next(iter(set)) falls -- deterministic across five runs, verified.
3. The evidence entry said five pre-existing records-mode tests fail under the
settle-before-rebuild injection; measured, it is six. And "three hundred
lines above" is four hundred.
