mergedFlagContractOtherwiseChanged was only ever exercised on the path where
every condition holds still, because `||` short-circuits: with no reviewed
entry the first operand already decides the outcome and the function is never
called at all. That left its five regression branches uncovered and put
changed-code coverage at 88.0952% against a 100% target.
Add the merge-path counterpart of the checkCompatibility bundled-regression
table, pairing each of shorthand / required / hidden / no-opt / scope with the
reviewed type change and requiring the type failure to reappear. Changed-code
coverage is now 100%.
The authoritative interface baseline and command-compatibility gates
rejected every flag type change on a historical command, with no review
channel — even when the new type only moves the same validation from RunE
to flag parsing. Both now consult a precise allowlist.
An entry must match command path, flag name and both type names exactly,
so it is direction-sensitive by construction, and it applies only when
nothing else about the flag moved (shorthand, required, hidden, no-opt,
scope). A bundled regression re-reports the type change.
The first and only entry is "dws minutes permission apply --policy" moving
from string to int (for #912): the old RunE parsed with
strconv.ParseInt(v, 10, 64) and enforced [2,4], the new one lets pflag
parse with base 0 and still enforces [2,4], so the historical set of
successful invocations is a subset of the new one. Base 0 additionally
accepts spellings like "0x3", which widens rather than narrows. Defaults
are excluded from the guard because the migration necessarily changes one.
In the snapshot gate the exemption resolves against the canonical
Command.Path, never the alias-expanded accepted path: an aliased command is
compared once per accepted spelling, so keying on that would let every
alias bypass the table.
The table is duplicated because check-authoritative-interface-baselines.sh
copies the whole scripts/policy/interface-baseline directory into a
worktree checked out at a historical revision and builds it there, so that
copy cannot import a package this branch adds. A guard test fails if the
two copies drift.
