tools/remote reworked to role-named commands (the builder-vs-built
tangle noted 2026-09-01): instance-install/instance-update/
instance-start manage the installed Werkator + werkdock, repo-init the
watched repository. The self-build is retired — no repo clone for
building, no GitHub-key step; the instance installs from locally built
artifacts (ADR 0006), the watched repo clones anonymously via https.
instance-update refuses to swap the runtime under a running build
(FORCE=1 overrides) and keeps the previous runtime as the rollback
asset. repo-init is idempotent: checksum-skipped rootfs upload, and the
machine-config guard is fixed — its indentation mismatch (grep for two
spaces, block written with four) appended the bwrap block on every run,
the source of the nine duplicates found on mih34. The retired
install/build/start commands fail loudly naming their successors.
docs/deployment.md gains the Hostsharing Managed Webspace as the third
deployment variant, written from the live-verified setup: both new
commands ran against mih34 (full update cycle; fully skipping re-init).

The runner no longer assembles raw bwrap argv: it checks image
existence via 'werkdock images', loads the rootfs archive once per
source as image werkator-buildenv-<hash> into werkdock's store (shared
across every repository of the OS user — resolving step 22's
buildenv-sharing question), and runs builds through 'werkdock run --rm'
with the git-metadata mask expressed as ordered -v/--tmpfs flags.
New pinned config key bwrap.werkdock (the executing binary, default via
PATH) — a branch must not substitute the executing binary; synced in
WerkatorConfig, BwrapOverrides, the pinned-key strip, the init
template, docs/configuration.md, and AGENTS.md.
werkdock's --clearenv means the server environment no longer leaks into
builds; the TMPDIR workaround is gone with the raw invocation.

tools/remote mixes commands that manage the builder (the installed
Werkator instance) with commands that act on the built (the watched
repository); on the self-building instance both roles coincide in one
product, which misleads. Session D's replacement must name the role in
every command and delegate built-side operations to the werkator CLI.

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.

Level 1: docker-compatible CLI (verbs, flags, loud refusal of isolation
flags the filesystem-only contract cannot honor) — built in session B.
Level 2: OCI image pull, flattened to a rootfs — deferred, stdlib-doable.
Level 3: a daemon speaking the Docker Engine API subset Testcontainers
actually uses (Testcontainers never calls the CLI) — deferred, but the
CLI is built as a thin frontend over the same internal service from the
start. Records the port-mapping crux of host networking and the
unprivileged-netns escape hatch as a future RFC.
Step 21 session B and the werkdock README follow the docker-shaped
semantics: run takes an image, instances correspond to containers.

Records where the bwrap work (PR #4) drifted from the intent of ADR 0006 —
the webspace self-build instead of local-build-plus-install — and breaks the
correction into four sessions: close step 17's open ends, bootstrap Werkdock,
let Werkator consume it, replace the self-build with the bundle install path.
The extracted sandbox tool is named Werkdock (decided after three naming
rounds, rationale and dropped candidates in the step file). It grows in the
werkdock/ subdirectory, seeded here with its README, and moves to its own
repository once it stands on its own.
