`bwrap` named the mechanism one layer below the tool that actually runs it: since
v1.0.0 Werkator does not invoke bwrap at all, it shells out to the werkdock CLI —
which made `bwrap.werkdock` a key naming its own executor.
The section is `werkdock` now and that key is `werkdock.binary`; BwrapConfig,
BwrapOverrides and BwrapBuildRunner follow the name. A file still writing `bwrap`
is read as before and warned about once per file, in `renameLegacySandbox` on the
raw map of every layer before merging — so nothing downstream knows two names, and
the old name is not a way around the pinning either. Renaming rather than refusing,
because the section lives in the machine configuration of every webspace instance,
which no repository tracks; the hard refusal belongs to the release that sets
ConfigVersions.FORMAT_BROKE_IN, where a file declaring no version can be caught
by name at all.
WERKATOR_SANDBOX in tools/remote follows, and still accepts `bwrap`.

instance-update stopped the unit and only then started the upload, so a transfer
that dies mid-way leaves the host with no running Werkator and nothing to start
again. That is not theoretical: deploying to vm4006 on 2026-09-03 failed with
"scp: Connection closed" with the service already stopped.
The upload now happens before the stop, and each artifact is transferred to a
.part file whose sha256 is compared with the local one before it is moved into
place, retrying twice. A truncated archive would otherwise unpack into a broken
runtime, which is worse than the failed transfer it came from.

tools/remote assumed the layout instance-install creates: the watched repository
in $WERKATOR_PATH/werkator, the runtime in $WERKATOR_PATH/.werkator, a werkdock
binary and a rootfs beside it, and the unit hardcoded as werkator-werkator.service.
An installation that predates the script — vm4006, a docker host with the repository
in ~/hs.hsadmin.ng and the runtime in ~/opt — could not be deployed with it at all.
WERKATOR_REPO_DIR, WERKATOR_INSTALL_DIR and WERKATOR_SANDBOX name the three values
that actually differ; their defaults are what instance-install writes, so the
existing env files resolve to exactly the same paths as before. The unit name is
derived from the repository directory the way SystemdServiceFiles.unitName does it,
instead of being spelled out. With WERKATOR_SANDBOX=docker the werkdock binary and
the rootfs archive are neither built nor uploaded — a docker host has no sandbox to
install, and check-prerequisites asks the docker daemon instead of werkdock doctor.

A deployment's ErrorDocument-covered downtime window looked dead: Apache's
default 502/503/504 error page, or a hung request, while instance-update
briefly restarts the systemd unit. init --systemd now also writes a static
werkator-maintenance.html next to the generated .htaccess, and the .htaccess
maps a refused connection straight to it — served by Apache alone, no
change needed to Werkator itself since it is exactly the process that is
down.

* refactor: werkdock/ verlässt dieses Repository
Die neun Commits unterhalb von werkdock/ sind per `git subtree split`
historieerhaltend nach https://git.javagil.de/mi/werkdock gehoben; hier
bleibt nichts davon zurück.
Mit dem Verzeichnis geht die Build-Definition `werkdock`: Sie beschrieb ein
Go-Modul, das der Kotlin-Build um sie herum nicht berühren kann — jeder
Werkator-Branch baute es dennoch als `<branch>@werkdock` mit. Drüben ist
sie die einzige und heißt `default`.
Die Kopplung bleibt, wie Sitzung C sie gemacht hat: Werkator ruft das
`werkdock`-Binary über PATH (`bwrap.werkdock`, weiterhin gepinnt), so wie
es `git` ruft.

* refactor(remote): das werkdock-Binary kommt aus einem eigenen Checkout
Bisher baute das Skript es aus dem Unterverzeichnis. Jetzt nennt
WERKDOCK_REPO den Checkout (Vorgabe: ein Geschwister dieses Repositories —
die übliche Ablage, wenn man an beidem arbeitet), WERKDOCK_BINARY das
gebaute Binary darin; beides ist wie jeder Transportwert aus der Umgebung
übersteuerbar.
Fehlt der Checkout, nennt die Meldung die Klon-URL, statt bloß „file not
found" zu sagen: Das Skript kann die Lage nicht mehr selbst beheben, also
sagt es, was sie beheben würde.

* docs: Sitzung E — Werkdock hat ein eigenes Repository
Plan-Schritt 21 bekommt die Sitzung, die die Herauslösung beschreibt, samt
Abnahmekriterium; Plan-Index und Architektur-Skill sagen nicht mehr, sie
stehe noch bevor, und der Deployment-Leitfaden verlinkt das Repository
statt eines Verzeichnisses, das es hier nicht mehr gibt.
Dazu das PR-Dokument nach Hausregel (docs/prs/README.md).

* fix(remote): repo-add wendet das Instanz-Fragment an
`repo-add` rief `werkator init` ohne `--apply`, `repo-init` dagegen mit.
Folge: Ein so aufgenommenes Repository bekam die Sandbox-Politik nicht —
`bwrap.rootfs` und `bwrap.werkdock` fehlten, und der erste Build lief auf
dem nackten Host statt in der Sandbox. Gefunden beim Aufnehmen von
Werkdock: `gofmt: command not found`, weil die Go-Toolchain nur im
Sandbox-Image liegt.

* fix(remote): repo-add erkennt einen ~/-Registry-Eintrag, und der Kommentar sagt die Wahrheit
Die Registry-Prüfung suchte nur den absoluten Pfad und meldete deshalb
„not registered yet“, obwohl der Eintrag als `path: ~/werkdock` dasteht —
eine Einladung, ihn ein zweites Mal einzutragen. Gegriffen wird jetzt
lokal, damit beide Schreibweisen ohne zweite Schicht Remote-Quoting
treffbar sind.
Dazu der Kommentar über dem Laden der Env-Datei: Er behauptete, die
ausdrückliche Umgebung gewinne. `set -a; source` weist unbedingt zu — die
Datei gewinnt. Beim Nachziehen des Werkdock-Fragments hat mich genau das
eine Runde gekostet.

`tools/remote` konnte genau ein beobachtetes Repository einrichten
(`repo-init`, fest auf $WERKATOR_PATH/werkator). Für eine Instanz, die eine
Registry bedient (ADR 0009), fehlte der Weg, ein zweites hinzuzunehmen —
und das braucht der Rollout unabhängig davon, welche Repositories es am Ende
sind.
`repo-add <url> [name]` klont daneben, führt `init` darin aus und PRÜFT, ob
die Registry den Pfad schon nennt — geschrieben wird sie nicht. `~/.werkator.yml`
ist die Datei der Instanz: Port, globale Nebenläufigkeit, womöglich geteilte
Zugangsdaten. Ein Skript, das sie in place umschreibt, verändert die
Konfiguration des Betreibers hinter dessen Rücken. Klonen und Initialisieren
ist mechanisch, Registrieren ist eine Entscheidung — also druckt es den
Eintrag und sagt, dass die Registry beim Start gelesen wird.
Der Name muss ein Pfadsegment sein: Er wird das Routen-Segment /repos/<name>.
docs/deployment.md verweist im Registry-Abschnitt darauf.

The wrapper's config writing is gone: --env-file FILE selects the
target instance (default .env; named like docker's flag — --env means a
single variable there), the init fragment named by WERKATOR_INIT_CONFIG
is uploaded and installed remotely via 'werkator init --apply', and
instance-start places the .htaccess that init now generates. The
heredoc/sed machine-config writing is deleted; control-token delegates
to the werkator CLI; check-prerequisites uploads werkdock and runs its
doctor — tools/werkator-build-prerequisites.sh retires. The idle-check
and port-forward port lookups read the effective config via
config:print, so a port living in the applied fragment is found too.
Verified live against mih34 with the .env.mih34 + .env.mih34.yml pair
(gitignored via the new /.env.* rule): update, doctor PASS 6/6,
repo-init applying the fragment as the new layer, instance-start
placing the generated proxy and restarting the unit, control-token.

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).

- PR-docs get their real numbers: bwrap-build-runtime -> PR#4,
build-current-head-from-the-branches-view -> PR#3 (files and scenario IDs)
- tools/remote: header note marking install's clone step and build as the
self-build prototype, superseded by session D of step 21 (usage range grown)
- ADR 0008: bubblewrap user-namespace sandbox as the third build runtime;
step 17 and the plan README now point at 0008 (0007 was taken by build
definitions before the step landed)
- AGENTS.md: decisions list catches up with ADR 0007 and ADR 0008
- architecture skill: BwrapBuildRunner paragraph (rootfs unpack, uid mapping,
mount ordering, pinned keys) and the dispatcher's three-way routing
- plan README: step 21 entry now describes the werkdock/ subdirectory path

* Add the bubblewrap build runtime (step 17, ADR 0007)
BwrapBuildRunner: third runtime behind BuildRunner for hosts without root
and without Docker (e.g. Hostsharing managed webspaces). Shells out to the
bwrap CLI, unpacks a prepared rootfs on demand into
.git/werkator/buildenv/<envKey>/rootfs, reuses the Docker runner's git
metadata mounts, and returns the attached bwrap process for streaming and
cancellation.
Config: bwrap.enabled/rootfs/env on BranchConfig and BwrapOverrides on
BuildDefinition; enabled/rootfs are pinned like the docker sandbox policy.
Docker and bwrap are mutually exclusive per build, rejected in
buildSettings instead of picked silently. DispatchingBuildRunner routes
bwrap; InitCommand template, docs/configuration.md and AGENTS.md in sync.
* bwrap rollout tooling: remote script, prerequisites disk/quota check, absolute workspace binds
- tools/remote: central remote control script with check-prerequisites, install and build commands
- tools/werkator-build-prerequisites.sh: compact PASS/FAIL output, target-dir parameter, free-space and
group-quota headroom checks against the ~5 GiB build footprint, home-filesystem reference
- BwrapBuildRunner: bind workspace and home at absolute paths resolved against repoDir — a relative
path made bwrap create mountpoints inside the read-only rootfs (seen on the webspace); regression test
- TestcontainersSmokeTest: gated with enabledIf docker available (skip, never fail, without a daemon)
- docs: configuration reference, step-17 plan notes, PR-doc
* bwrap: bind the repo read-write before the workspace so mountpoints are creatable
bwrap creates mountpoints for bind destinations inside the sandbox; with only a
read-only rootfs bound at /, creating them for the workspace under .git/werkator/
worktrees failed with 'Read-only file system' (seen on the webspace). Binding the
repo dir read-write first provides the base; the git metadata mounts then layer
the usual isolation on top (read-only .git, tmpfs mask over .git/werkator,
read-write worktree admin dir).
* bwrap: pre-create bind mountpoints inside the unpacked rootfs
bwrap mkdirs mountpoints for bind destinations against the sandbox view; with the
rootfs ro-bound at / every destination missing from the rootfs (the repo dir under
/home/storage/... on the webspace) fails with 'Read-only file system'. The rootfs
directory is a plain host dir, so create the mountpoints there before launching
bwrap; it then finds them and has nothing left to create.
* bwrap: skip existing rootfs files when pre-creating bind mountpoints
/etc/resolv.conf is a file the rootfs already ships; createDirectories threw on it.
Only missing directories are created now.
* bwrap: pre-create proc/dev/tmpfs mountpoints in the rootfs too
The rootfs archive ships no /proc or /dev (excluded when packed), so bwrap failed
mkdir'ing their mountpoints against the read-only root.
* bwrap: bind the workspace after the git metadata mounts
The tmpfs mask over .git/werkator shadowed the earlier workspace bind, because the
worktree lives under .git/werkator/worktrees — chdir then failed with ENOENT. The
workspace bind now comes last and shadows the mask at exactly its own path.
* systemd resource limits and webspace start command (step 17, web access)
- server.systemd.memoryMax/tasksMax (empty = directive omitted): on platforms where
the service runs in a shared memory slice (Hostsharing Managed Webspaces) a
runaway Gradle build must not starve the whole package; init --systemd reads the
effective config and bakes the values into the generated unit
- tools/remote werkator start: writes server settings (assigned port, loopback
bind, publicBaseUrl, nginx off) plus the Apache reverse-proxy .htaccess into
~/doms/<domain>/subs/www, runs init --systemd and enables the user unit
- docs/configuration.md documents the new keys
* tools/remote: env-based configuration and background port-forward
All connection and deployment values come from .env in the repository root
(WERKATOR_REMOTE, WERKATOR_PATH, WERKATOR_PORT, WERKATOR_DOMAIN,
WERKATOR_LOCAL_PORT, optional WERKATOR_BRANCH/MEMORY_MAX/TASKS_MAX/ROOTFS);
missing values fail with a pointing error instead of positional parameters.
- port-forward is now 'tools/remote port-forward start|stop' with a detached
ssh tunnel, pid file under /tmp, and idempotent start
- start restarts the systemd unit after updating the machine config
- control-token generates the token in place when the server has not yet
- the rootfs archive default moves to build/ (already gitignored)
