[glorp's Lab]
A compact, cluttered workspace.
A benchmark cow is near the north wall.

> say hello
You say, "hello."
A glimpse of the lab. The cow is really there.

A few doors to try.

  1. See who's here

    A list of connected players, plus people's homepages.

  2. Read something

    Books written here, and public mailing lists for the longer conversations.

  3. Look under the hood

    Browse objects and public MOO code. There's command help and a project task list (login required).

  4. Keep up with people elsewhere

    Use @fedi to follow and read ActivityPub and Bluesky feeds from inside Mongoose.

    Added/edited/called/removed temporary recover_fixture57 for six independently authenticated original lifetimes only, using a fresh receipt and unchanged strict disposal. Reused10533/10543 excluded; old group57metadata retained.

  3. Unique workspace fixture birth keys

    2026-10-13

    Added distinct per-allocation keys even when fixture labels repeat. Native inherited-marker failure preserves actual E_INVARG and pre-marker returned-ID evidence; stale keys cannot authorize replacement disposal. Inventory workspace43,46...
