The backend already lets one adopted container back several cases pointing at
different in-container directories, but using it meant retyping the container
name, host and workspace one by one — exactly the friction that leaves a
capability unused. Picking an existing case from a dropdown now carries those
three over, leaving only the two fields that must differ: the case name and the
in-container directory.
Clearing those two is the point of the feature, not a convenience: keeping the
old name is refused by the server as "case already exists", and keeping the old
directory is refused as "a twin case on the same container and directory". Both
errors are clear, but a form pre-filled with values that are guaranteed to be
rejected is a trap. Focus lands on the in-container directory — the thing the
user came here to change.
⚠️ Only adopted containers are listed (docker.owned === false). A Codeman-built
container's lifecycle belongs to its one case — a second case would be torn out
by that case's recreate or delete — so the server refuses it anyway, and listing
it here would only manufacture a baffling error. `owned` may be absent and absent
means owned, so the test is `!== false`, not truthiness.
CaseInfo.docker gains containerWorkdir and owned for this: the former is the
"which directory does this case use" half of the picker, without which the user
cannot tell what to change it to; the latter backs the filter above. ⚠️ Both
places that build a docker CaseInfo (the list endpoint and the single-case query)
must set them — filling in only one makes the picker work or not depending on
which read path was taken, and a test pins "exactly two".

Once a container is adopted, it could not be adopted a second time. But a
container usually holds more than one project directory, and opening a case for
another one had no path forward except starting a second container — precisely
what adoption exists to avoid.
The original reason was in a comment: two cases sharing an adopted container
would make one case's teardown race the other's launch on the same tmux server.
That reason does not hold. The in-container tmux session name is
dockerTmuxSessionName(sessionId), i.e. codeman-dkr-<id8>, keyed by SESSION and
not by case, and buildDockerKillCommand tears down exactly that name, so killing
A never touches B — hosting multiple sessions is what a tmux server is for.
The other three routes into an adopted container's lifecycle do not pass through
here either, confirmed one by one: the stop and remove builders throw outright;
recreate refuses `owned === false` before it even resolves the container name;
and orphan reaping filters on `label=codeman.managed=1`, which a user-built
container does not carry — a structural exclusion.
That leaves exactly three cases worth refusing, none of them tmux-related, split
into the pure, unit-tested classifyAdoptContainerConflict:
- owned-case the container belongs to a Codeman-created case, whose lifecycle
Codeman manages: one recreate or delete there would pull the
container out from under the adopting case.
⚠️ `owned` may be absent and absent means owned (cases predate
the field), so the test is `!== false`, not truthiness.
- other-owner already adopted by a different user. Adoption hands out a shell
inside someone else's container.
- duplicate same container, same directory. The second case would behave
identically to the first, so name the existing one rather than
silently minting a twin. A different in-container directory is
the case this change exists to support and passes.

`backdrop-filter` promotes an element to its own compositing layer. A
position:fixed full-screen layer that is created and then hidden was measured to
leave a stale hit-test region behind in Chrome: the page renders perfectly, but
pointer events across the viewport go nowhere.
The report came from a long-lived tab connected to a remote server, where a
connection blip shows and then hides #offlineOverlay. The symptoms were a
terminal that would not scroll and, at the same time, an unrelated
click-to-expand that also stopped responding, while a freshly opened tab was
fine; a read-only console command (getComputedStyle + elementFromPoint, both of
which force a hit-test recomputation) then cured it. Two unrelated features
dying together and one read-only command fixing both points at hit-testing
itself rather than at either feature.
So the `backdrop-filter` moves onto the actually-visible selector and the layer
is never created while hidden. Only the two persistent overlays change:
offline-overlay (toggled with [hidden]) and file-preview-overlay (toggled with
.visible). path-picker and path-preview are created and removed by JS, leave
nothing behind, and are untouched.
⚠️ This is an evidence-based inference, not a fix verified by reproduction:
reproducing it needs a long-lived page that has been through a connection blip,
which I could not manufacture in a controlled environment. The guard test pins
both halves — no such property while hidden, and a real blur while shown — so a
later cleanup cannot quietly delete the effect.

handleInit() did not distinguish a first load from an SSE reconnect: it always
cleared the terminal caches in _resetAllAppState() and re-ran selectSession() for
the session that was already on screen. Every reconnect therefore refetched up to
1 MiB of buffer and reset+rewrote xterm. On a link that drops a connection about
once a minute (measured at ~57s intervals against a healthy server) that reads as
the page refreshing itself and throwing away your reading position.
A reconnect that lands back on the still-open session now keeps the terminal
caches and activeSessionId and resyncs through _onSessionNeedsRefresh(). That
path still reloads the buffer, so output produced during the outage is not lost,
but it preserves distance-from-bottom — the same rule #259 established for a
refresh the server triggered rather than the user. The WS is reconnected
explicitly when it is not already on that session, since skipping selectSession()
skips its _connectWs() call.
First load (gen === 1) takes exactly the path it took before.

(cherry picked from commit 435569c76e)
Browser input is delivered exactly once by (clientId, seq). The server records a
watermark per clientId and discards anything not above it as a duplicate — but
acknowledged it with an ACK indistinguishable from "applied". The client then
dropped the record from its queue, the UI looked perfectly normal, and the
terminal received nothing at all.
The counter is persisted to localStorage through a debounced write. Kill the page
between "sent" and "persisted" and the restored counter is below the server's
watermark, after which every keystroke lands under it, is discarded, and is
ACKed. Reloading does not help: the clientId is restored from localStorage
alongside that stale counter. Measured on a real session — typing into the same
session from a fresh browser (new clientId, no watermark on the server) worked
perfectly, which is what localised the fault to client state.
Three changes:
- on rejection the server replies {"t":"ia",seq,"dup":true,"last":<watermark>}.
It still ACKs, so the client can drop the record from its queue, but it now
says the input was not applied and supplies the number needed to climb out.
- on `dup` the client lifts its counter above the watermark and re-queues.
⚠️ Only records whose FIRST delivery is being retried are re-sent: a retry
judged duplicate means the mechanism is working (the original did arrive), and
re-sending would type the same text twice.
- the counter is now persisted synchronously. The queue payload can stay
debounced, but the counter is the thing that has to survive a crash, and
leaving it on the lossiest path cancels the only guarantee there is.
⚠️ Reading the watermark is defensive: the session arrives through a structured
port, and a port missing that method must not take the whole input path down —
a throw inside the handler means the ACK is never sent and the record is stuck in
the client queue forever, which is worse than the ambiguity being fixed. A mock
port's test timeout is what exposed this.

claude advertises "Jump to bottom (ctrl+End)", so that chord has to actually
reach it. But PASSTHROUGH_KEYS carried only the bare forms (End -> \x1b[F) and
CTRL_KEYS held just six letters (c/d/l/z/a/e), which cannot express End. Ctrl+End
therefore failed in both directions:
- with an empty composer it went out as a bare \x1b[F, the modifier silently
dropped, so the CLI received a plain End;
- with text in the composer the forwarding branch requires empty, so nothing was
forwarded and the browser default applied — the caret jumped to the end of the
draft, which is the "the shortcut now edits my input box" the user saw.
Encode them as CSI 1;<mod><final> instead, and forward Ctrl/Alt-modified
navigation keys whether or not the composer is empty: they are commands for the
CLI, and the composer has no editing semantics for them worth preserving (bare
Home/End still use the old table and edit locally).
⚠️ Bare Shift is deliberately excluded: Shift+arrow selects text in the composer,
a real editing gesture that must stay local. Shift held together with Ctrl/Alt is
still encoded into the modifier mask.
(cherry picked from commit 3fbaadadfb)
In a native terminal running a TUI with mouse tracking on (claude, codex), Shift
is the "let me select text" modifier: it bypasses the application's mouse
reporting so the emulator selects locally. Users bring that habit here, where it
did nothing — measured, `hasSelection` was already false during a Shift+drag and
no clearSelection call ran at all, because there was never a selection to clear.
The mismatch is that the two Shifts mean different things. xterm reads Shift as
"force selection", but that path is only taken when the application really has
mouse tracking on. The server strips the mouse DECSETs for claude/codex/gemini
(isAltScreenStripMode), so xterm's mouseTrackingMode is permanently `none`, that
branch is unreachable, and Shift instead lands in _onIncrementalClick — which
EXTENDS an existing selection. Extension is a no-op while selectionStart is
empty, so the drag had no anchor.
So plant the anchor xterm is missing. The listener sits on the capture phase of
the `.xterm` root, an ancestor of the `.xterm-screen` that SelectionService binds
to, and therefore runs before xterm's own mousedown; xterm then extends from our
anchor and the drag behaves like any other. Length is 0 so a Shift+click without
a drag does not select a stray character. An existing selection is left alone —
that is a genuine extend gesture, and xterm handles it correctly.
Right-click copies the selection (the mintty/PuTTY convention), completing the
gesture: until now there was nowhere for a finished selection to go. With no
selection the native menu is not hijacked — taking it away while offering
nothing in return is a pure loss.
(cherry picked from commit 7ab5015737)
Format check failed twice, on different files each time, because three prettier
versions were in play: package.json says ^3.4.0, package-lock pins 3.8.3 (CI runs
npm ci, so that is the one CI uses), and the local node_modules had 3.9.6. Files
formatted with 3.9.6 were then "fixed" with 3.4.2, pushing session-routes and
system-routes onto a third style — every version change moved the failure to a
different set of files.
Line-break placement in `await import` and a union type only; no logic changes.
The run menu still offered every mode for an attached container. The browser's
actual request showed why:
POST /api/docker-cases/adopt-preflight -> 400
{"error":"Invalid input: expected object, received string"}
_api serializes `body` and sets Content-Type itself, and three call sites each
passed an already-stringified body, so it was encoded twice and the server saw a
JSON string where it expects an object. curl was fine throughout, so nothing in
the server logs pointed at it.
Also fixes the design defect underneath: a failed probe fell through to "do not
gate", which silently offered every mode. When the container has been recreated,
is stopped, or the engine is unreachable, the user sees claude, clicks it, and
it can only fail — with the reason visible nowhere. A failed probe now hides
every agent mode (Shell needs no CLI and stays) and shows the server's own
reason at the top of the menu.
Two static guards switched from a character window to brace matching. They
sliced between two call sites, and _loadRunModeHistory's call appears above its
definition, so the slice came out empty and the assertion verified nothing —
the same trap twice in one file.
Both paths in the adoption form had to be typed. Each gets a Browse button
using the same path-input-group markup Link Existing uses, so the two look and
behave alike.
What they can browse differs, and that is the point. The host workspace path
reuses the existing host picker. The container workdir cannot: an adopted
container has nothing mounted at a matching host path, so a host listing would
be a different filesystem — and getting this field wrong is the source of the
opaque OCI chdir error at launch, which makes it the field that most needs to
be clickable.
Adds a read-only POST /api/docker-cases/browse: one `ls` through docker exec, no
writes, no lifecycle, path shell-escaped like every other value. `ls -Ap` marks
directories with a trailing slash and keeps names with spaces intact.
PathPicker takes an optional fetchListing source rather than being forked: the
container variant only swaps where the rows come from, and reuses the rendering,
navigation, Up and Choose/Select unchanged.
Link Existing's Browse did nothing: GET /api/filesystem/browse answered 403
"No filesystem browse roots are available".
Two rules were fighting. /root is a default blocked tree in the attachment
guard, and Codeman running as root — containers, plenty of servers — makes
homedir() exactly /root, so the picker's own allowlisted Home root was blocked;
the other candidates live under it or do not exist. The root list came out
empty and there was nothing the user could open.
The blocked trees exist to keep ~/.ssh and friends out of reach, not to seal off
the user's own home. Only trees that would swallow a configured root whole are
dropped now: /root goes when Home is it (or sits inside it), /etc holds no
configured root and is untouched. Secrets stay protected — isSensitivePath
independently matches .ssh/, .env and credentials* at any depth, and it is what
the directory probe asks about.
⚠️ Navigation must reuse the same narrowed list the roots were chosen with.
Handing the raw trees downstream admits a root and then refuses every path
inside it, which reads as a picker that opens and does nothing.
Attaching a container, picking claude and hitting Run gave one line —
`execvp(3) failed.: No such file or directory` — and the run-mode menu offered
every mode. Three separate defects, found on a real deployment.
TmuxManager.createSession resolved the CLI directory without distinguishing a
docker session, so a host with no claude threw, the catch fell back to a direct
PTY, and that PTY exec'd the CLI on the HOST. The failure surfaced as a bare
execvp error naming nothing. A docker session runs its CLI inside the container;
the host does not need it. All eight modes now sit behind a cliRunsInContainer
guard, and whether the container has the CLI is settled by the adoption
preflight or the image gate before launch.
The running check used a bare double quote and command substitution. The whole
chain is embedded in an outer `bash -c "…"`, so the unescaped quote closed that
string early and the remainder was re-tokenized. It is now a `grep -qx` pipeline
using only the single-quote form every other line in the builder already uses.
Claude Code refuses --dangerously-skip-permissions as root. Our base image runs
a non-root user, so an owned container never hit this; an adopted container's
user belongs to its owner and is frequently root, and keeping the flag killed
the pane with a message visible only inside the container. The preflight now
reports runsAsRoot and the launch chain drops the flag for it.
The menu also showed every mode because the container CLI probe only started
when the menu opened. It is warmed when the case is selected instead.
Storing the container's CLIs on the case at attach time left two gaps: a case
linked before that field existed has none at all, and a container's CLIs can be
installed or removed long after it was linked. A real deployment hit the first
one — the host had only codex, the container only claude, and with no stored
list the menu still gated on the host and hid the mode that actually worked.
The probe now runs when a container case is selected, reusing the existing
adopt-preflight endpoint, so there is no new backend surface. Results are cached
per case for the page's lifetime, since the menu opens often and the probe is a
`docker exec` round trip; a concurrent probe for the same case is deduplicated
with an in-flight marker.
A failed probe leaves the cache empty, which the caller reads as "unknown" and
therefore does not gate. Hiding every mode because one probe failed is worse
than offering one that turns out to be missing, which the launch path already
refuses with a specific message.
The repaint only happens while the menu is still open, so a late answer cannot
make the list jump under a user who already closed it.
The adoption preflight used the mode name as the binary name. claude, codex,
opencode, gemini and pi happen to match, so it never showed — but antigravity
ships as `agy` and deepseek as `dsh`, so a container that has either was
reported as not having it, and the mode was silently dropped from the case.
Adds a MODE_BINARIES map, single-sourced with defaultDockerCommandForMode, which
launches those same binaries. Probing and result filtering share one `binaryFor`
so the two cannot drift apart.
The run-mode dropdown hides CLIs that are not installed on the HOST (#201). That
is right for local sessions and wrong for a container case, whose agents run
inside the container: a host with no claude installed hides the mode while the
container ships one, which is exactly what happened on a real deployment.
The adoption preflight already probes what the container has, so that result is
persisted on the case and surfaced through CaseInfo. Docker cases gate on it;
every other case keeps the host probe unchanged.
An absent list reads as "do not gate" rather than "nothing available": an owned
container runs our base image, which ships every CLI, and treating unknown as
empty would leave the menu with Shell alone.
Typing a container name from memory is error-prone. The field becomes a native
datalist: pick from the engine's containers, type to filter, or type a name that
is not listed (the engine may be remote, or the container may not exist yet).
A datalist gives all three natively, so no dropdown state machine is introduced.
Adds listDockerContainers and GET /api/docker-hosts/:hostId/containers, following
the listRemoteCodemanSessions discovery precedent: read-only and never throwing,
so an unreachable daemon returns an empty list and the field degrades to plain
text instead of erroring.
Stopped containers stay in the list, sorted after running ones and labelled.
Attaching does require a running container, but hiding stopped ones turns "my
container is not in the list" into a dead end, while showing
`Exited (137) 8 days ago` says exactly what to fix.
The new strings were English only. Adding entries surfaced a deeper problem: the
translator matches whole text nodes and skips `code`/`pre`, so an inline `<code>`
mid-sentence splits a hint into fragments that can never match an entry — which is
why the panel's existing "Build it once with <code>...</code>" hint was never
translated either.
Drops the inline markup from the new hints so each is a single text node, then
adds the zh-CN entries. The brand name goes through the existing {name}
placeholder.
Server-side error bodies are deliberately not added: the client receives them
already interpolated with a concrete container name, so a template key could
never match.
Attaching lived only on the Docker tab, but the place users look for anything
container-shaped is the "Run in an isolated Docker container" checkbox on Create
New. A feature nobody can find is a feature nobody has.
Adds a one-click link there that switches to the Docker tab, turns the toggle on
and focuses the container field. Reuses switchCaseModalTab and the existing sync
helper; no new CSS.
Two defects that only a real container exposes.
The probe chained `command -v X && echo X` with semicolons, and a script's exit
status is its last command's. A container without the last probed CLI made the
whole `sh -lc` exit 1, so a perfectly healthy container with tmux and claude was
reported as "could not exec into the container". A missing CLI is data here, not
failure, so the script now ends with `exit 0`.
containerWorkdir defaulted to hostWorkspacePath. That default holds for an owned
container only because the create-time bind mount puts the host directory at that
exact path; attaching mounts nothing, so the two are independent facts. A host
path absent inside the container makes `docker exec --workdir` fail with an OCI
chdir error that surfaces in the pane as a bare "execvp failed". The preflight now
proves the directory exists inside the container and refuses at link time.
The Docker tab gains an "Attach to an existing container" toggle. Ticking it
swaps the create-time fields (image, network, advanced) — which describe a
`docker create` attaching never runs — for the container name, and routes the
submit to the adopt endpoint.
Reuses the existing linkDockerCase flow end to end: only the final call differs.
The docker-host upsert still applies, since it is what resolves the
engine/context/daemon for `docker exec`; its create-time fields are simply never
read for an attached case.
Docker cases could only run in a container Codeman created itself. Attaching to
one the user already built and runs means Codeman must leave that container's
lifecycle completely alone, which the launch chain could not do: it was
`image inspect` -> `inspect || create` -> `start` -> `exec`.
Adds `DockerCase.owned`, mirroring the `owned:false` contract remote-SSH already
uses for attached sessions. Absent (every existing case) means owned, so current
behaviour is byte-identical. `false` means the container belongs to the user and
Codeman may only exec into it.
The launch chain for an attached container only looks, then execs: no image gate
(the image is theirs), no create, and no `start` — starting a container we do not
own is the very mutation attaching promises not to perform. A missing or stopped
container fails closed with an actionable message instead. Credential seeding is
skipped too: those copies read from create-time read-only mounts that do not
exist here, and writing host credentials into someone's container is not ours to
do, so its CLIs must already be authenticated inside it.
Four fail-closed guards. buildDockerStopCommand and buildDockerRemoveCommand
throw during pure string construction, so no caller bug can turn into a
`docker stop`/`rm` on a container we do not own; removeDockerContainer refuses
again at the lowest layer; drift reports "none" for an attached container, which
carries no `codeman.confighash` label and would otherwise always look drifted and
409 the launch gate forever; and the orphan reaper skips attached containers
through a check deliberately independent of the two conditions already covering
them.
`owned` is applied AFTER the config hash is computed. dockerConfigHash takes an
explicit field list, so ownership can never shift an existing case's hash — if it
did, every pre-existing case would trip the drift gate at once, and the remedy
the UI offers is "recreate the container".
Adds POST /api/cases/docker-adopt and a read-only
POST /api/docker-cases/adopt-preflight. The preflight refuses at LINK time rather
than at session launch, where the only ways out would be a dead pane or starting
a container we do not own.
Tests assert the negative guarantee directly — that create, start, stop, rm,
restart and kill are absent from the generated commands while `docker exec -it`
and `new-session -A` remain — since it cannot be observed by using the feature.
