schema-compatibility is the third check in the same Interface Integrity job,
after the two CLI interface gates. It also rejected every published parameter
type change outright. Because the earlier gates failed first and `set -e`
stopped the step from ever running, this one never surfaced in CI, so the
previous exemption only covered two thirds of the problem.
checkParameterCompatibility now consults a precise allowlist: the tool path,
parameter name and both type values must match exactly, making it
direction-sensitive by construction, and it applies only when nothing else the
gate checks about the parameter moved (default, interface_default, format,
property, interface_type, required, cli_required, required_when, enum). The type
check moved to the end of the function so the carve-out can see those findings;
ordering is unobservable because the result is sorted.
The only entry is "minutes/minutes.apply_minutes_permission" parameter "policy"
migrating from "string" to "integer" (for #912). That type is projected from the
Cobra flag type (provenance cobra_flag_type), so it describes how the CLI accepts
a value. Consumers build a command line from it, and "--policy 4" is the same
argv under either declaration — a quoted "--policy \"4\"" still reaches pflag as
4 — while RunE keeps enforcing the same [2,4] domain. The parameter maps to
property "policyId", which the command has always sent as a number, so "integer"
is closer to the actual request than "string" was.
Table values must be the canonical form schemaType emits: the JSON encoding of
the type keyword, so `"string"` with its quotes rather than a bare string. The
guard test recomputes both through schemaType and checks the decoded name
against the closed JSON Schema type set — reviewedInterfaceRefRedirect was
silently disabled twice by exactly this class of spelling mistake.
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.
