# 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.
