Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughAdded filesystem-based tests that compare each product-group plugin’s declared schema range with shipped schemas. The tests also verify plugin coverage and require ChangesPlugin schema validation
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Other Merge Risk: 🔵 Low · up to Filesystem errors can make the new schema-range tripwires miss drift rather than fail. Propagate traversal errors before merging so coverage remains reliable. 🚥 Pre-merge checks | ✅ 6 | ❌ 1❌ Failed checks (1 warning)

In `@crates/dpp-tests/tests/plugin_schema_range.rs`:
- Line 99: Update shipped_versions and the four directory-iteration sites to
return io::Result and propagate each DirEntry error instead of using flatten().
Ensure callers handle the resulting errors while preserving the existing
version, count, and set validation behavior.

Closes #330.
All ten plugins'
schema_version_rangewere stale at once before #322 — aluminium 1.1.0 against 1.2.0, battery 2.6.0 against 2.7.0, electronics 1.2.0 against 1.4.0, furniture 1.1.0 against 1.3.0, and so on for all ten. They were corrected by hand, which is the mechanism that let them drift, so the correction has the same shelf life as the last one unless something holds it.Two tests in
crates/dpp-tests/tests/plugin_schema_range.rs, no production change.Why it drifted invisibly, and why that argues for fixing it now
The range is read by nothing at dispatch: the host calls
check_compatibility(…, None, …)and aNoneschema version skips the check entirely. A value nothing reads cannot fail, which is exactly how ten wrong bounds across ten crates survived.So this is a trap rather than a live defect — and worth closing while it is one. When schema enforcement is switched on, ten stale bounds become ten wrong answers at once, and which way each is wrong decides whether it refuses a valid passport or accepts one it cannot handle.
What is asserted, and what deliberately is not
max_versionequals the highestvX.Y.Z.jsonthe group ships.min_versionnames a version that exists — not that it is the lowest. A plugin may legitimately stop accepting an old shape and nothing has decided it may not; requiring the lowest would encode a policy nobody stated. This still catches a typo.plugins/sector-*and that rename already emptied a glob silently once.{mattress, unsold-goods}, each with its reason inGROUPS_WITHOUT_A_PLUGIN. A thirteenth group arriving unplugged is a group whose compliance determination nothing makes.🚨 Watched to fail — five mutations, not one
A guard nobody has seen fail is unverified, so each case was reproduced:
tyre/v1.2.0.json, plugin untouchedv1.9.0+v1.10.0shipped, max declared1.9.0declares max_version 1.9.0 but 'tyre' ships up to 1.10.0min_versionset to0.9.0declares min_version 0.9.0 which 'toy' does not shipread 9) and the unplugged setnames product group 'widget', which ships no schemasThe second is the one worth keeping. A string comparison ranks
v1.9.0abovev1.10.0, so a lexical sort would have passed that mutation while silently treating a real version as the highest. Versions are parsed to(u64, u64, u64); the failure message naming1.10.0is the proof.Two things found while writing it
dpp-domain's registry pulls every version in withinclude_str!, so a missing file breaks the build of a crate this test depends on. That path is therefore guarded more strongly than any test could; theships no schemasbranch is reachable only for a new plugin naming a group the registry never got, which is the variant exercised above.parse_versionhadunwrap_or(name)where it neededunwrap_or(core), so a bare1.2.0parsed asv1and every plugin was reported as malformed. Caught by the test failing on its first run rather than by review — noted in a comment at the line, since the fallback being the already-stripped string is the non-obvious part.Verification
