The image-name pattern allows dots, so a directory like broken.tmp —
an interrupted load's staging dir — counted as an image. List now skips
.tmp names and Load refuses them, closing the ambiguity the previous
commit's (accidentally pushed red) test exposed.

Session C groundwork: Werkator's git-metadata mask needs a tmpfs
BETWEEN binds (ro-bind .git, tmpfs .git/werkator, bind workspace), so
-v and --tmpfs now collect into one ordered mount list and RunSpec
carries Mounts instead of Binds. --tmpfs DEST is the docker flag of the
same name. `werkdock images` lists loaded image names one per line, so
a consumer can check existence through the CLI. -v accepts the explicit
:rw docker default instead of refusing it.

The minimal build-capable CLI decided in RFC 0002's outcome: stdlib-only
Go module, one static binary.
- engine: RunSpec behind the Engine interface (RFC 0001); the Bwrap
engine ports Werkator's hardened invocation — uid-0 mapping, read-only
rootfs at /, proc/dev/tmp/root before the user binds so binds below
them land inside, mountpoint pre-creation in the rootfs including file
mountpoints, and a guard against binds escaping the rootfs. --clearenv
gives docker-style clean environments (HOME/PATH set explicitly).
- store: images under $WERKDOCK_HOME (default ~/.werkdock), load
unpacks via the tar CLI into a tmp dir and renames atomically.
- cli: docker-shaped run flags (-v/-e/-w/--rm); refused docker flags
(-p, --network, --memory, --cpus, --user, -d) fail loudly with the
reason; exit codes follow docker (125 CLI errors, child code through).
- doctor: port of werkator-build-prerequisites.sh — userns probe with
the three signals, tar/zstd, free space and group-quota headroom via
testable df/quota parsers, same PASS/FAIL output.
- tests: argv golden test, mountpoint and escape tests, flag refusals,
store round trip, doctor parsers — plus real-sandbox integration
tests that skip where bwrap or userns are unavailable.
Also records in step 21: RFC 0002 levels 2/3 deferred; next goal is
sandbox builds of Werkator, Werkbaum, and Werkdock itself.
