fix(volume): restore read-only native classification across API versions

[chen21019]

Cause and scope

The current Volume role overlay and packaged v1 role schemas omit isNative. The native unallocated-volume UI correctly requires an explicit false value, so eligible rows remain hidden.

Change

Expose only volume.isNative:r and supplement only the missing frozen v1 field from the existing core schema. No CRUD/action expansion, client mutation, database migration, frontend missing=false fallback or runtime patch.

Verification

18 targeted local tests passed with zero failure/error/skip; six new regressions cover actual frozen schemas, readonly processing order, complete unchanged action payloads, response true/false preservation and POST/PUT mutation exclusion. CI requires the named regressions. Formal artifact/startup and QA8080 native lifecycle acceptance remain pending; no full matrix claim.

Release

New numeric Engine candidate 0.183.332; existing tags are untouched. README, compatibility contract and candidate release note are aligned. Rollback restores the former missing-field behavior; no persisted data changes.

[chen21019]

Superseded by #74 at immutable source 7a625ee. The failed CI run remains evidence; required named-case selection is corrected without relaxing all-suite failure or security gates. No release was published from #73.
