M12-05B Status

status: done task: declare per-format import/export local/server and feature support updated: 2026-08-18 America/New_York enablingTask: false parityStateChange: false

Scope

The schema-1 capability matrix binds all seven M12-05A runtime formats and the inventory SHA-256. Each format has separate IMPORT and EXPORT entries with local and server routes plus explicit geometry, material, and animation feature status. A runtime operator being registered does not make a Web route executable.

The only READY route is the existing bounded GLB EXPORT local path. All seven IMPORT routes and all server routes are explicit BLOCKED/IO_FORMAT_UNSUPPORTED; other local exports are also blocked. GLB export features are marked PARTIAL with the M12-06 round-trip dependency. Unimplemented operations stay UNVERIFIED rather than claiming geometry/material/animation support.

Evidence

node --test web/tests/unit/io-format-capability-matrix.test.mjs passed 3/3, including duplicate format, ready-without-executor, unverified-ready-feature, and missing blocked-code negatives.
node tools/web/check-io-format-capability-matrix.mjs passed; the matrix generator reproduced the committed JSON byte-for-byte and runtime statuses matched the M12-05A inventory.
The checker reports 7 formats, 1 local bounded GLB export route, and 27 blocked routes.

Next Task

M12-05C: prevent matrix-undecared combinations from appearing in file selection and operator search.

Rollback

Remove the capability matrix protocol/generator/checker, unit test, matrix, golden manifest, and this status entry. Restore M12-05A as the queue tail and move the machine queue back to M12-05B. No parity ledger rollback is required.
