remove_project_volumes always returned Ok(()) regardless of what actually
happened, making the `if let Err(e)` guarding it at every call site dead
code. remove_project then dropped the project record unconditionally, so a
volume, image or container that failed to delete became permanently
unreachable — confirmed against a real orphaned volume pair found in the
wild (fixes #31).

remove_project_volumes/remove_snapshot_image/remove_container now report
what they could not remove (treating "already gone" as success rather than
a leftover), remove_project surfaces this to the user via a toast, and
before dropping the project record it writes a pending-cleanup record that
startup housekeeping retries automatically on the next launch.

shadow-testandClaude Opus 5 d09e2a2743 Stop using a live credential as a test fixture
`the_custom_env_fingerprint_never_carries_the_value` asserted that the custom-env
fingerprint does not leak a secret — using the maintainer's real Gitea token as
the secret. It was committed on 2026-08-11 in 9b2f4fe, reached 92 commits, and
was readable for fourteen days in the public GitHub mirror at
`shadowdao/triple-c`, confirmed by fetching the raw file.

The token was a **site-admin** token (`is_admin: true`, user id 1) with admin
rights on every repository the account can see, not a repo-scoped one. It has
been revoked; the API now answers 401.

Release bundles were never affected — the literal is inside `#[cfg(test)]`, and
a search of the shipped 0.4.62 AppImage finds nothing.

The fixture is now an obviously fake string, and the test is unchanged
otherwise. Mutation-checked against the replacement: a fingerprint that returns
the raw value, one that returns the key name, and one that ignores its input are
all still caught, so nothing about the test's power depended on the value being
real — which was true the whole time.

History is deliberately **not** rewritten. The value was public for two weeks, so
rotation is the fix and the old value is now worthless; rewriting 92 commits of
published history would break every clone to hide something already seen.

Worth noting how this survived: five audit rounds and two independent reviews
all pointed at new code, and this sat in a test file that none of them had reason
to open. A high-entropy-literal check in CI would have caught it on the day.

Two independent reviews of 2c9482a, one for correctness and one against the
threat model. Between them they found two ways to lose a file, one way for a
container to choose a Windows save destination, and a rule that made every
dotfile unsavable. Every finding below was demonstrated against a real
container before being fixed, and the fixes are demonstrated the same way.

## The download was accepting truncated reads and refusing whole ones

The `[ -f ]` bracket around the read was wrong in both directions.

It missed the case that loses data. Truncation *in place* — `> file`, log
rotation, `tar -x`, most build tools — leaves a regular file behind, so `dd`
stopped at the new EOF and exited 0. Measured: a 600 MB source truncated
mid-read delivered 34 MB, which was then renamed over the user's own earlier
copy and toasted as `Saved (34.1 MB)`. Truncate-to-zero did the same and needs
no adversary at all.

And it failed *good* downloads. `dd` already holds the fd, and neither `rm` nor
`mv` can touch an open one — the bytes are complete. But `rm` makes `[ -f ]`
false, so a finished 600 MB transfer of a file a bundler happened to unlink was
deleted, reporting "nothing was saved". The comment claiming the bracket caught
a "mix of two files" was simply wrong; an open fd cannot be a mix.

So the script now measures the file before reading it and puts the answer on
stderr, and Rust checks that at least that many bytes arrived. One rule,
subsuming everything the bracket was for. Verified against a real container:
truncation mid-read and the FIFO race are refused; deletion, rename-over, a
growing file, an empty file and an untouched 600 MB read all pass.

## On Windows the container, not the user, was naming the save destination

`suggested_save_name` split on `/` only, and it feeds the save dialog's
pre-filled name. Backslash is a legal Linux filename character and
`validate_container_path` has no reason to object — `..\..\Users\…` is one
POSIX segment. The Windows common file dialog parses its name box as a path on
Save, so a container-created file called
`..\..\..\Users\vic\AppData\Roaming\Microsoft\Word\STARTUP\x.dotm` put its own
bytes in an auto-loading Office directory on one un-read click. `resolve_host_path`
did not stop it: Word's `STARTUP` and Excel's `XLSTART` are not in the autorun
denylist, which this file's own docs already concede is "losing by
construction" and was never meant to be the boundary here.

The name is now sanitized of every separator, the drive colon and the rest of
what NTFS refuses, so it cannot be a path on any platform this ships to.

## No dotfile could be saved, and the app pre-filled the name that guaranteed it

The write policy judged the leaf for hiddenness, so `/workspace/.env` was
refused *after* the modal and the overwrite prompt — quoting the name the app
itself had suggested. `.gitignore`, `.dockerignore`, `.eslintrc.json`, `.nvmrc`:
all unsavable, while uploading them worked, so a dotfile could go in and never
come out.

`HostPathUse` gains a third mode. `WriteChosenName` drops the leaf check and
keeps every directory rule, and only `download_container_file` uses it — the
dialog is a real boundary for that caller and only that caller.
`download_container_backup` still takes its path over IPC as a string and keeps
the strict rule.

## Smaller, all found by the reviews

  * A download had no ceiling. `dd` resolves through the container's `PATH`,
    which its agent owns with passwordless sudo; a replacement writing forever
    was measured at ~6 GB/s, so one click on a file listed as 2 KB filled the
    host disk with no progress shown and no cancel. Bounded now by what the
    file measured, with slack that is absolute for small files and
    proportional for large ones, so an honest growing log is unaffected.
  * "Framed rather than verbatim" did not stop container text reaching the
    toast headline: `readableRefusal` matches with `includes`, and it has to,
    because the app's own refusals carry those markers mid-sentence. Anchoring
    would break them. The fix is at the injection point — container text is
    clipped to one 200-character line with control characters stripped — plus a
    `max-h-40` on the toast message, which the `detail` block always had and
    this half did not. 8 KB of prose in a `z-[60]` card pushed its own dismiss
    button off-screen.
  * `savingPath` was a scalar while the design deliberately allows concurrent
    saves. Starting a second freed the first's row mid-transfer, and whichever
    finished first cleared both; dismissing the second dialog was enough. It is
    a `Set` now.
  * `setUploading(false)` fired when the command settled, not when the refresh
    finished, so a second click landed mid-relisting.
  * `upload_files_to_container` checked the container directory before the
    picker and then used the unresolved path. A modal has no time limit. It
    re-checks after, which is what `docker::exec`'s doc comment already claimed.
  * `wait_for_exec_exit` flattened a missing exit code to `Some(0)`, which made
    the new `!= Some(0)` check unreachable by construction.
  * `normalize_host_path` did not collapse repeated separators, so the lexical
    system-root rule was silently absent for `C:\\Windows\…`. Not exploitable —
    the resolved pass catches it — but a documented layer that does nothing is
    a trap for the next caller.
  * README still carried the "no host path crosses IPC in either direction"
    claim the previous commit narrowed everywhere else, and HOW-TO-USE
    described the hidden rule without saying it applies to folders only.

480 Rust tests, 602 frontend, no new clippy warnings. Eleven mutations against
the new tests, all killed — two of the first round survived and were rewritten:
one because `split_whitespace` already handled the case I thought I was
testing, one because I had deleted a comment rather than the behaviour.

`upload_file_to_container` and `download_container_file` existed on main before
any of this work started. "Ship the Files tab container-side only" removed them
and called it narrowing scope; from a user's side it was a regression they
upgraded into. This restores the feature.

The reason for the removal was real — four consecutive audits found their
criticals in host paths crossing IPC — so the feature comes back only in the
shape that removes the class rather than patching it a fifth time. The dialogs
are opened by **Rust** (`pick_save_path`, `pick_files_to_upload`), not by the
webview. A frontend `open()`/`save()` handing the backend a path string is
exactly what failed, and the backend cannot tell such a string from one a
compromised webview invented. Now the webview can ask for a picker and that is
the whole of its influence: it cannot name a host path as an input. That is the
shape the previous round's own notes named as the honest one if this ever
returned.

None of the machinery the audits condemned returns. No `link(2)` destination
reservation, no placeholder rollback, no collision marker: the OS save dialog
already asks about overwriting and Docker's extractor overwrites on upload the
way `cp` does, so there was nothing left for it to do. Download reuses the
sequence `download_container_backup` has been using unchanged — resolve, stream
into a partial file beside the destination, rename last — so a failed transfer
never touches the file that was already there. Upload reuses the terminal
drop's hardened uploader, with the container's uid/gid resolved once per
selection rather than once per file.

Against a container that is actively hostile rather than merely surprising:

  * the read is `dd iflag=nonblock`, not `cat`. `[ -f ]` and the `open` after it
    are two syscalls and the container owns the filesystem in between; a loop
    swapping the file for a FIFO wins that race, and `cat` then blocks forever
    with no writer and no timeout anywhere on the path — the `invoke` never
    settles and a partial is left in the user's directory for good. Verified in
    a real container that `cat` hangs, that `iflag=nonblock` returns, and that
    it is byte-identical on a regular file.
  * the read is bracketed by a second `[ -f ]`, because non-blocking turns that
    hang into an empty file that would otherwise be renamed over the
    destination and reported as a successful save.
  * an *undeterminable* exit code is a failure. Backup catches this class with
    its `total == 0` check, which download cannot have because an empty file is
    a legitimate save; without a replacement, a project restarted mid-download
    renames a truncated partial over the user's file and reports the byte count
    as if it were whole.
  * container stderr is capped. Every other reader of container output in the
    tree is capped for this reason; the two streaming commands were the
    exception, and stdout was bounded by disk while stderr was bounded by
    nothing.
  * the script's refusals are framed rather than used verbatim, so a directory
    named to look like one of our own sentences cannot become the toast
    headline through `readableRefusal`.
  * the partial name is capped at NAME_MAX. A bundler's 230-character content
    hash is a name that fits its directory and produces a partial name that
    does not.

Also: a non-UTF-8 dialog path is refused by name rather than silently mangled
into a different path by U+FFFD substitution; both actions carry in-flight
state, so a second click cannot open a second dialog and a slow save is not
indistinguishable from a dead button; and the upload's completion message names
the directory, since the picker is modal and the user can browse elsewhere
while it is open.

Not restored: drag-and-drop, in either direction. `drag:allow-start-drag` stays
ungranted and `hold/disk-and-dragout` still holds that work.

Two bugs the new tests caught while being written: a double-click on "Save to
host…" opened the file viewer on top of the save dialog, and an N-file upload
made N redundant execs to re-ask `id -u`.

Docs that asserted this feature did not and must not exist are corrected —
CLAUDE.md, README, HOW-TO-USE, TECHNICAL and the capability threat model. The
"no host path crosses IPC" claim is deliberately narrowed to the inbound
direction: paths do still travel outward inside error text, canonical ones
included, and the reviewed record should not overstate.

600 frontend tests, 473 Rust, no new clippy warnings. Every new test was
mutation-checked; four that survived their first mutation were rewritten,
including two whose mutations turned out to be unfaithful and one that was
blind to a dismissal leaving a row stuck on "Saving…".

The handler returned `false` from xterm's custom key handler and a
comment claimed that was enough to stop the bare CR. It is not.
`_keyDown` returns the instant the handler says `false` — before it sets
`_keyDownHandled` and before it cancels the event — and `_keyPress` then
checks that same flag, finds it false, and emits a bare CR for Enter's
charCode 13.

So the headline feature of this branch did the wrong thing in a real
browser: Shift+Enter inserted the newline and then submitted the
half-written prompt, now with a stray blank line in it. Arguably worse
than before the fix. Reproduced in Chromium and confirmed against the
bundled xterm 5.5.0 source.

`preventDefault()` is what stops the browser firing keypress at all.
Applied at both call sites — the desktop terminal and the web terminal's
copy.

The test could not have caught this. jsdom never synthesizes the
follow-up keypress, so `expect(sent()).not.toContain("\r")` was asserting
a property the environment cannot falsify — a test named for a behaviour
it could not exercise. It now asserts `defaultPrevented`, which is the
mechanism that actually suppresses the keypress and which jsdom can
observe. Mutation-checked: removing the `preventDefault()` fails it.

Docs and disclosure. HOW-TO-USE.md's settings table still described the
pre-fix behaviour — and help_commands.rs fetches that file from GitHub
main at runtime, ahead of the embedded copy, so it would have reached
every user's Help dialog the moment this merged. The Config tab named
three settings that need a base-image update; there are four, and the
omitted one (Session recap) is the one that fails *without* the "won't
switch off" symptom the warning teaches. Both now also state the cost
nobody had written down: changing any of these recreates the container,
which commits a layer.

Two stale comments that told a reviewer the code was safe when it was
not. compute_claude_code_settings_fingerprint still claimed the
historical fingerprint is preserved so an upgrade cannot churn every
container — carried over from before the widening, false since the
format string changed. And capabilities/default.json, which is the
reviewed threat model of record, described a "Save to host…" action this
branch deletes.

Security and correctness. update_settings validated env vars and nothing
else, so the *global* default_ssh_key_path — the fallback for every
project without an override — took `/` and read-only bind-mounted the
host, which entrypoint.sh then copies into the home volume. classify_
mount_source ran canonicalize on the raw string, which resolves a
relative path against Triple-C's own cwd, so `.` and `..` were accepted
or refused depending on where the app was launched; the daemon then
refuses the mount and the project can never start. Its test passed only
because its examples did not exist under app/src-tauri.

bind_mount_exclusions still derived a path from every row while
project_path_mounts had learned to skip unmountable ones, so a legacy
row made /workspace/<name> ordinary container content that a migration
would then exclude from staging and destroy. The skip is also logged now
rather than silently dropping a folder.

The terminal's file-in path checked is_dir() but not file type, so a
dropped FIFO blocked forever with no timeout — and it is the only route
in now. The web terminal labelled sessions from a global set at request
time, so two quick opens swapped them; harmless until Shift+Enter became
type-dependent, at which point a mislabelled Claude session submitted a
half-written prompt. Opened now carries the type.

Every ~/.claude.json write goes through one atomic helper. The
awsAuthRefresh branches still truncated in place — the same corruption
the Shift+Enter block was fixed for twenty lines later, and its own
comment said so. Demonstrated: a failed write now leaves the original
byte-identical.

And the registration test I added yesterday could pass while the
property was false: an audit got five real unregistered commands past its
exact-string attribute match, and "exactly once" was in its name but not
its body. Mutation-checked against all six shapes.

shadow-testandClaude Opus 5 4d1a5a2417 Remove list_sibling_containers, which nothing called
It listed every container on the daemon — including the user's unrelated
postgres, mysql and other work — and handed the summaries to the webview.
It had a registration, a command, a docker-layer helper, a typed frontend
wrapper and a `SiblingContainer` type, and zero call sites.

An audit named it as step one of an escalation chain: enumerate the
daemon's containers, then point `update_project`'s unvalidated
`container_id` at one and read its files through the file-command
surface. The second half of that chain is closed now, but a command that
exposes the user's unrelated containers and serves no feature is surface
with no upside.

Found by the registration test added in the previous commit, which is the
answer to "why test something the compiler already checks": the compiler
is perfectly happy with a command nobody calls.

shadow-testandClaude Opus 5 11216c45e3 Assert every command is registered, and every registration exists
This is the shape of the bug behind the original OAuth-callback report:
`set_auth_bridge_enabled` existed, worked, and had a typed frontend
wrapper — with zero call sites. The switch the docs told users to flip
was wired to nothing, so every login callback was refused. Both halves
compiled, so nothing noticed.

The reverse direction is the sharper one: a command that is registered
but reachable from nowhere is still IPC surface a compromised webview
can call. `list_sibling_containers`, which returns every container on the
daemon including the user's unrelated work, sits in exactly that state.

Mutation-checked both ways: removing a registration fails the test,
restoring it passes. The first parser I wrote split the list on commas,
which glued each `// Docker` style comment to the command after it and
then dropped that command as a comment — silently, once per group, 17 in
total. Line-based now.

shadow-testandClaude Opus 5 913aa85805 Stop the pre-commit scrub running with its guards silently absent
Two fail-open gaps, both latent on the shipped image and both live on an
ImageSource::Custom one.

`--one-file-system` is the only bound on the scrub's `rm -rf`, and it was
probed into `$rmopt` with `rm --one-file-system --help`. BusyBox answers
that with `unrecognized option` and exits 1, so on any busybox- or
toybox-derived image the variable was empty and the delete ran as root
across mount boundaries — reported as a completed `Reclaimed(n)`.
Measured in `busybox:latest` with a named volume one level below the
match at /tmp/claude-x/inner: emptied, `###TRIPLE-C-SCRUBBED 102423`. It
is a prerequisite now, probed by `rm --one-file-system -f -- ''` — the
code path that matters, with the one operand no filesystem can name — and
an image without it prints `###TRIPLE-C-SCRUB-UNAVAILABLE` and deletes
nothing. That costs Alpine and busybox images their scrub, which is the
cheaper half of the trade: declining costs disk, proceeding costs the
mount.

The second is that resetting `PATH` was never the whole of command
lookup. `bash` builds functions out of `BASH_FUNC_<name>%%` environment
variables, function lookup precedes `PATH` entirely, and `command -v`
reports a function as found — so a planted `stat` passed the prerequisite
probe and then answered the containment checks. Every in-shell answer is
itself importable: `unset`, `command`, and — the point that settles it —
`[`, `pwd` and `cd`, which are checks 0 to 2 rather than merely the
tools. So the script is no longer run by the shell that read the
environment. The exec's argv is a bootstrap using only reserved words,
parameter expansions and command words containing a `/` (which `bash`
refuses to import a function for), and it hands the script as `$1` to a
second `/bin/sh` started by `env -i`. Measured on `/bin/sh -> bash` with
`BASH_FUNC_stat%%` set on the container and a volume mounted at the
match: the old invocation emptied it and printed 306565, the bootstrap
left it intact and printed 65536. `/usr/bin/env` then `/bin/env`, because
H3's lesson about hardcoded coreutils locations applies to `env` too.

The comment claiming the `PATH` reset "defeats it just as completely as
spelling /usr/bin/stat out" is corrected, as is the one claiming a
sudo-written /usr/bin/stat does not survive a container restart — it
lands in the writable layer, which is exactly what the commit this runs
in front of captures.

Also here: a stored project path row with an empty host_path or
mount_name no longer becomes a mount. The first sends `field Source must
not be empty` back for the whole create, so the project cannot start at
all until the row is gone, and no amount of save-time validation reaches
a record already on disk; the second mounts over /workspace itself and
the daemon then creates the other rows' mount points inside the user's
real folder.

And in migration_commands, the deferred-reconcile claim is RAII rather
than a trailing statement — a panic inside `reconcile_migration_now`
stranded it for the rest of the process — and `await_release` looks
before it sleeps, so a project released a moment later no longer costs a
full twenty seconds.

shadow-testandClaude Opus 5 06ccb4d818 Ship the Files tab container-side only
Four successive audits found the same thing: host filesystem paths crossing
IPC is where the criticals in this work live. The most recent one found the
`link(2)` upload reservation returning success against a *directory* (linking
into it, leaving permanent stray files, and via a symlink-to-directory writing
outside the validated write root), failing every upload permanently on any
filesystem without hard links, and the post-resolution credential check
weakened from a general rule to an eleven-name denylist.

Rather than fix that a fifth time, the Files tab ships as what it is good at:
a browser, viewer and renamer that never touches the host.

Removed: `upload_file_to_container`, `download_container_file`, and everything
that existed only for them — the whole reservation (`UPLOAD_RESERVATION_SCRIPT`,
`reserve_upload_destination`, the placeholder rollback, `exec_oneshot_as_within`
which had no other caller), `stream_container_file_to_host`, `ChannelReader`,
`save_to_host`, the download ceiling, and the collision marker with its
frontend contract. On the frontend: the upload button, the pane's
`onDragDropEvent` handler, both "Save to host…" affordances, `uploadPaths` /
`downloadFile` / the overwrite prompt, and `OverwriteConfirmModal`.
`lib/uploadErrors.ts` is now `lib/refusalText.ts` and keeps only the half that
turns any backend refusal into the sentence a person reads.

Kept, and not weakened: `upload_host_file_to_terminal` and
`download_container_backup`. They predate this work, their hardening is a real
improvement over main, and they are now the whole answer to "how do I get a
file in or out" — drop it on the Terminal, or Back up container. The drop gate
(`lib/dropTarget.ts`, `PaneVisibility`) is untouched.

`resolve_host_path` gets the general hidden-component rule back. Round 3
replaced it with `HOST_CREDENTIAL_DIRS`, which is allow-by-omission for the
rest of `$HOME`: `~/.local/bin` (write there and you own the user's next shell
command), `~/.password-store`, browser profiles and `~/.pki/nssdb` were all
reachable through a planted symlink with a visible name — verified against a
real home directory, and all five refused now. It over-catches `.pnpm` and
`~/.cache`; for two occasional callers that is the cheaper mistake, and the
refusal says which folder it resolved through.

Two defects fixed while in here:

  * A symlinked directory listed as empty. `find` defaults to `-P`, which does
    not follow a symlink even as the starting point, so `-mindepth 1` discarded
    the only match and a real directory rendered as "Empty directory" — a
    first-order defect now that browsing *is* the feature. `-H` follows the
    starting point and nothing else, so a loop is `ELOOP` rather than a walk
    that does not end; verified against a live container for a symlinked
    directory, a broken link and a loop. `find`'s errno for the loop case is
    now a sentence.
  * `finish_download`'s replace path fired on *any* rename failure with a
    destination present — a vanished partial, a permission error, a directory
    at the destination — and deleted the user's file to complete a move that
    could not complete. It is now fenced to Windows (where a rename onto an
    existing path genuinely fails) and to a partial that still exists.

shadow-testandClaude Opus 5 9472cb3c4c Resolve host paths before mounting them, and stop reading stored data as choice
Four fixes that share a shape: a value already on disk, or one spelled
around a check, being taken at face value.

`/..` bind-mounted the entire host filesystem read-write. `is_filesystem_root`
was purely lexical — trim trailing separators, refuse what was left only if it
was empty or a bare `C:` — and nothing in the file ever called `canonicalize`,
so `/..`, `/./`, `/home/..`, `/etc/../` and `C:\..` all passed. The daemon
resolves them: `docker run -v /..:/mnt/probe` mounts the host root, and the app
mounts read-*write* into a container whose agent has passwordless sudo. It is
the escalation `check_mount_name_stays_under_workspace` exists to close,
reached through the host-path half of the mount instead of the mount-name half.

`classify_mount_source` replaces it and asks the OS: `canonicalize` applies
`..`, follows symlinks, and resolves 8.3 aliases and UNC spellings on Windows.
A path that cannot be resolved — `projects.json` synced from another machine,
a folder not created yet — falls back to a lexical collapse rather than being
refused, because refusing would make such a project unsavable; the gap is
bounded, since what resolution adds is a property of paths that exist. A path
that names no location at all (`C:x`, a relative path) is refused rather than
guessed at. Same check now guards `ssh_key_path` and `ca_cert_path`, whose
read-only mounts were whole-host disclosure at /tmp/.host-ssh.

Custom env var names had no charset check anywhere, so `BASH_FUNC_stat%%` —
bash's wire format for an exported shell function, body in the value — reached
the container environment verbatim. Latent today because the image's /bin/sh is
dash, but the pre-commit scrub runs `/bin/sh -c` as root and nothing pins that.
Keys are now shell identifiers, on the project and the global list both, with
the same grandfathering the folder rows get: a stored key is admitted, a new or
edited one is not.

The blank workspace row was persisted. The comment said it was dropped on save;
the code computed the filtered list and then saved the unfiltered one, so
"+ Add folder" plus a blur stored `{"Target": "/workspace/", "Source": ""}` and
the project could never be started or recreated again. Every save in the
section now goes through one filter, and a blur that changed nothing saves
nothing.

Widening the five `ClaudeCodeSettings` booleans to `Option<bool>` reinterpreted
every stored record. They were plain `bool`s that always serialised, so every
project ever saved carries an explicit `"env_scrub": false` that nobody chose —
and under the new merge that `Some(false)` beats a global `Some(true)`, where
the old rule let the global win. Upgrading silently turned five settings off,
"strip credentials from subprocess environments" among them. Deserialisation
now goes through a shim that dates the record by the presence of the
pre-widening `enable_session_recap` key and reads its `false`s as unset. The
fields skip serialising when unset, so an older binary can still parse
`projects.json` after a downgrade — a `null` would fail to parse and take the
whole list down, since `ProjectsStore` parses all-or-nothing.

shadow-testandClaude Opus 5 dd23a52b41 Fix four upgrade-path defects the coherence audit found
The ~/.claude.json write was `printf ... > "$CLAUDE_JSON"`, which
truncates before it writes. A write that fails part-way — a full home
volume, which is the exact condition half this release exists to prevent
— leaves the file unparseable, and it never self-heals: the next start's
jq fails on the corrupt file, MERGED is empty, and the guard skips the
write that would have repaired it. That file holds the OAuth account, so
the failure mode is a permanently lost login, in service of a cosmetic
flag that suppresses a tip. Demonstrated: old pattern loses the
credential, new tmp+rename leaves the original intact. The correct
pattern was already in triple-c-task-runner.

The web terminal scoped its xterm key handler to Claude sessions but not
its mobile input bar or its dedicated newline button, so both sent ESC+CR
into `bash -l`, where readline has no binding for it. Silent no-op, and
worse from a button that stays on screen looking live. Both now consult
the active session's type, and the button is disabled with a reason on a
shell tab.

The Config tab claimed "Off overrides a global On" without qualification.
True for the env-var-driven settings, false for TUI mode, Effort level
and Focus mode, whose off state is *removing* a key — an older base
image's entrypoint ignores the instruction to remove it. The copy now
says so and points at the base-image update.

HOW-TO-USE.md said there is no add-task form; AutomationTab renders a
"New task" button. That file is fetched from GitHub at runtime by
help_commands.rs, so the error was live in every user's Help dialog.

shadow-testandClaude Opus 5 168b61d632 Close two cross-file handoffs from the round-3 fixes
The terminal's drop target derived the tar entry name from the host path
*after* symlink resolution, so dropping ~/Downloads/latest.log — where
latest.log is a symlink — landed the file in the container under the
target's name. Nothing errored; the user got a name they never typed. The
Files pane had the identical bug and was fixed with `host_upload_name`;
the terminal now calls the same helper, so the two drop targets cannot
drift. It also drops the "dropped-file" fallback, which silently renamed
anything the old `file_name()` could not parse.

`migration_store::load` told the user a backup existed when it had
deliberately not written one. `load` runs on every reconcile, survey and
reaper pass, so a persistently corrupt record reaches MAX_CORRUPT_BACKUPS
within seconds; from then on the copy was skipped while the log still
read "(a copy was kept at <path>)". Three outcomes are now distinct, and
the "enough already" case says so rather than naming a file that is not
there — that being the message someone reads immediately before going to
look for their data.

shadow-testandClaude Opus 5 00128f9b1a Make the scrub work off /usr/bin, and stop a log level deciding whether it runs
H3 — the pre-commit scrub was a silent no-op on any base image whose coreutils
are not under /usr/bin. Hardening against a PATH-planted `stat` shim by naming
every tool absolutely bought nothing the `PATH` reset on the first line had not
already bought — the shim lives in the persisted home volume, and uid 1000
cannot write /usr/bin or /bin — and it cost the whole feature on Alpine, which
Settings -> Docker -> Custom accepts. Measured on one seeded tree in a real
container: the absolute-path script printed `###TRIPLE-C-SCRUBBED 0` and left
every planted file in place; the PATH-resolved one reclaims 77824 bytes. The
default image is unchanged at 521038.

It was silent three times over, and all three are fixed:

* The script now probes for all six things it needs (`command -v` for the five
  tools, plus the root device id reading back as a number) and, if any is
  missing, prints `###TRIPLE-C-SCRUB-UNAVAILABLE <what>` and no total at all.
* `scrub_writable_layer` reads that marker first and returns a new
  `ScrubOutcome::Unavailable`, warning with what the image is missing; a
  genuine `Reclaimed(0)` now leaves a debug line rather than nothing.
* `commit_log_suffix` renders `Reclaimed(0)` as "ran and found nothing to drop"
  rather than "0.00 MB dropped", which is what a scrub that could not run used
  to look like.

Verified in real containers: the mount-at-the-match defence still holds with a
home-volume `stat` shim first on PATH (the volume survives; deleting the PATH
reset from the same script empties it, so the harness can tell the difference).

H2 — the pre-migration scrub had been folded into `log::info!`'s argument list
to satisfy `#[must_use]`. `log::info!` expands to `if Info <= max_level() { … }`,
so the awaited scrub lived inside the level check, and `logging::init`
tolerates `dispatch.apply()` failing — which returns before `set_max_level` and
leaves the process at `Off`. In that state the scrub never ran and the layer
was committed into the longest-lived snapshot the app takes. The outcome is
bound first now, `logging::init` restores the level on failure and says so on
stderr, and a test scans all four files for an `.await` inside any `log::*!`
argument list.

Also:

* `reconcile_migration` deferred a held project instead of dropping it. Its
  only caller fires once per "Docker became available", so a project held at
  that instant was never revisited for the session — phase un-normalised, no
  resume or rollback offered, pin left `Claimed`. It now waits for the holder
  to let go (20s x 90, one waiter per project) and reconciles then.
* The scrub's byte total counts what a partly failed `rm` removed, by
  re-measuring rather than dropping the whole subtree on a non-zero exit —
  which was exactly the `--one-file-system` case.
* The scrub exec blanks `LD_PRELOAD`, `LD_AUDIT` and `LD_LIBRARY_PATH`.
  `LD_PRELOAD` is in none of the reserved env families, so a project's custom
  env var reached a root exec and injected code into every tool the scrub runs,
  `PATH` reset or not. Verified against Engine 29.7 that `docker exec -e` wins.
* The device test is described honestly: it is a mount test under `overlay2`
  and not under `vfs`, where checks 1 and 2 are what still hold.

shadow-testandClaude Opus 5 39934299f9 Stop the snapshot retry being an unconfirmed revoke, and unbrick legacy configs
Three things, all reachable from a single credential-handling round.

**The "Retry snapshot cleanup" button deleted the token.** `clear_claude_token`
called `secure::delete_claude_oauth_token()` unconditionally; the `mode`
argument only changed the toast wording, so there was no sweep-only path on the
wire. The leftover panel rendered on `leftover !== null` alone and
`onAuthenticated` never cleared it, so the sequence revoke -> snapshot skipped
-> re-authenticate from the button directly above -> press the retry the panel
is still offering threw away the token acquired seconds earlier, announced by a
message about images. The deliberate Revoke needs a confirmation modal; this
needed nothing.

`sweep_claude_token_snapshots` is the honest primitive: it rewrites the images
and never touches the keychain. The images are the durable record, so the retry
re-derives its work from Docker and needs no stored token. Re-authenticating
now clears the panel, and the Authenticate button is disabled while a cleanup
runs — a sweep is a per-image inspect/create/commit/rmi over the Docker socket
and takes minutes.

**Sweep-first left the token live for that whole window.** The keychain delete
sat behind `list_images` plus the per-image loop, at bollard's 120s-per-request
default, while the UI said "Revoking...". A quit or crash in there and nothing
was revoked at all; worse, `has_claude_token` stayed true and
`shared_claude_auth` reads the keychain at container-*create* time, so a
project whose `SecretScrub` guard had already released could be started later
in the same sweep and be handed a fresh copy of the credential in its env.
Keychain-first now, and the comment that claimed "no window in which a scrubbed
image is re-poisoned" — true of images, silent about containers — is corrected.
The reorder's original justification (crash-mid-sweep recoverability) is what
the sweep-only command covers.

A keychain refusal no longer discards a scrub report, because nothing has been
swept yet, and both remedies stay on screen: Revoke, and the image sweep, which
is now offered in every state rather than only when nothing is stored.

**`update_project` validating every folder list bricked existing projects.** It
validated nothing until recently while `WorkspaceSection` saved `{paths}` on
every blur, so `projects.json` can hold a half-filled row, a mount name with a
space, a duplicate, or `/` as a host path. Any such project became entirely
unsavable — every Config toggle, every permission-mode change and
`useTerminal.ts`'s tab rename came back with a message about folders — and
refusing the save did not unmount anything. `validate_project_paths_update`
admits a row carried over verbatim from what is stored and holds a new or
edited row to every rule, which keeps the escalation closed: introducing a bad
value through this command is exactly what a non-carried-over row is. The
`/workspace/../tmp/claude-x` chain is the one exception and runs on every row
regardless, because a stored one is live data loss rather than untidy data.

`ssh_key_path` and `ca_cert_path` had no check at all; a filesystem root there
read-only bind-mounts the whole host at /tmp/.host-ssh. Refused on change, with
the same grandfathering.

Tests are mutation-checked: reverting to sweep-first fails all four new Rust
ordering tests, pointing the retry back at `clear_claude_token` fails five
frontend tests, and validating an update in isolation fails the legacy-data
tests.

shadow-testandClaude Opus 5 c6086b0ab3 Stop the file panel refusing ordinary paths, and hanging on a FIFO
H6 (HIGH) — `resolve_host_path` canonicalised the host path and then re-ran
the *lexical* policy over the answer, hidden-component rule included. Because
canonicalisation resolves through symlinks, that rule started judging where a
path happens to live rather than where the user pointed: uploading out of a
dependency under pnpm (`node_modules/pkg` → `node_modules/.pnpm/…`) was
refused, and so was every download into, or upload out of, a visible directory
that leads to `~/.local/share`, `~/.cache`, `~/.var/app`, `~/.nvm` or
`~/.cargo`. None of it was refused before the H4 fix landed.

The two questions are now separate functions. `validate_host_path` judges the
string the user chose, unchanged. `validate_resolved_host_path` judges the
canonical form for the things only it can answer — the system roots (a Mac's
`/etc` *is* `/private/etc`), the login-item directories, and a new
`HOST_CREDENTIAL_DIRS` list. That last one is what keeps H4's escape closed:
`Downloads/pub` → `~/.ssh` with a leaf of `authorized_keys` is refused because
of where it lands, not because of how the directory is spelled. macOS handling
is untouched — `/private/tmp` stays out of `HOST_SYSTEM_ROOTS` and
`/var/folders` stays in the exceptions.

H8 (HIGH) — the upload reservation claimed its destination with
`sh -c 'set -C; : > "$0"'`, and the comment claiming that is `O_EXCL` was
wrong for a destination that is not a regular file. Against a FIFO the shell
opens it and blocks in `open(2)` forever; `exec_oneshot_raw` has no timeout, so
`upload_file_to_container` never returned and the Files pane sat on
"Uploading…" for the session with the rest of the batch abandoned. Verified in
a fresh ubuntu:24.04: the old form times out and the blocked `sh` stays in
`ps`; the new form answers in 35 ms.

The reservation is now a `link(2)` — it claims a name atomically, never opens
anything, and `EEXIST` is immediate whatever is in the way. A staging file at
an unguessable name in the same directory is linked into place and unlinked,
under a `trap … EXIT`. `exec_oneshot_as_within` adds a wall-clock ceiling as
the second line of defence, opt-in per call site so migration's `apt-get` is
unaffected. The upload contract is unchanged: default-refuse,
`overwrite: Option<bool>`, and `FILE_EXISTS: <full container path> already
exists`.

Also fixed, all in the same surface:

* A dangling symlink destination was a permanent dead end — `set -C` refused,
  the confirming `test -e` followed the link and said no, and raw shell text
  came back with no Replace on offer. `link(2)` does not follow the new-path
  link, and the script confirms with `[ -L ]`, so it reports as a collision.
* An upload through a symlink renamed the file: the leaf came off the
  *resolved* path, so `~/Downloads/latest.log` landed as `2026-08-23.log` and
  the collision prompt named a file the user never chose. The name now comes
  from the path the user gave; the resolved path is still what gets opened.
* `download_container_backup` leaked its partial file when the descriptor
  check fired. It now tracks `created` the way `stream_container_file_to_host`
  already did.
* The failed-upload cleanup was `rm -f` on a path that, the reservation having
  succeeded, held whatever was written in the interim — a host file under
  `/workspace/…`. It now removes only an empty regular file, and the comment
  says what it is doing.
* `resolve_container_dir` parsed a combined stdout+stderr buffer as a path.
  It uses the split-stream helper, like the listing next to it.
* `verify_opened_path` failed open on a readlink error (`if let Ok(actual)`).
  A check that cannot see is not a check that saw nothing wrong; the macOS
  compile-time no-op is now spelled out too.
* A trailing slash on a write path resolved to the directory itself.

Nine new tests, all mutation-checked against the pre-fix behaviour. Two more
cases added to the ignored live-Docker test: a FIFO and a dangling symlink,
both timed.

shadow-testandClaude Opus 5 ed91423666 Hold back the Disk panel and OS drag-out from the ship branch
This is a scope reduction, not an abandonment. Both subsystems are
preserved in full on `hold/disk-and-dragout` and are intended to come
back once they have been hardened separately. Nothing here is a
judgement that the features are unwanted — three successive
audit-and-fix cycles each closed a critical defect in these two areas
and each opened a new one, so the rest of the round ships now and these
two get their own cycle rather than holding it up.

Removed: the Disk settings panel and its whole reclaim / destroy /
compaction surface — `DiskSettings`, `DiskProjectTable`, `useDiskUsage`,
`docker/disk.rs`, `disk_tests.rs`, the disk commands in
`docker_commands.rs`, and their `generate_handler!` entries. Dropping
the IPC entries is the point: a UI-only removal would have left five
commands callable by a compromised webview, one of them a verified
arbitrary-DELETE primitive. `sweep_orphaned_snapshots`'s *command* goes
with them (the panel was its only caller); the sweep itself stays.

Removed: OS drag-out from the Files tab — `stage_container_file_for_drag`
and its host staging lifecycle, the pointer gesture and `dragPreview`,
`stageForDrag` / `isStagedHostPath`, the `tauri-plugin-drag` and
`@crabnebula/tauri-plugin-drag` dependencies, and the
`drag:allow-start-drag` capability grant, which could not be scoped.
The capability test's expected list is updated; its `*:default` and
`store:*` assertions are untouched.

Kept, deliberately: drag-and-drop *into* the app (Files pane and
terminal) and "Save to host…", which is now the only route out of a
container. The prevention work is untouched — the pre-commit scrub and
`SNAPSHOT_SCRUB_PATHS`, capped container logs, the `triple-c.base` /
`triple-c.managed` labels, `sweep_orphaned_snapshots` and the startup
housekeeping, the migration pin/probe reapers, scheduler log pruning,
`formatBytes.ts`, and `project_lock.rs` in full with every acquisition
site outside `disk.rs`.

Entanglements, resolved rather than deleted blind:
* `container.rs`'s `a_compaction_runs_this_module_s_scrub_script_byte_for_byte`
  pinned the compaction Dockerfile against `snapshot_scrub_script()`.
  Dropped — it existed only for compaction. `snapshot_scrub_script` and
  its containment tests are untouched.
* `lib.rs`'s startup reap of `:compacting` tags and `triple-c-compact-*`
  containers is dropped: nothing on this branch creates them.
* `project_lock`'s `Compaction` / `CacheClear` variants and
  `any_held_excluding`, `migration_commands::is_migrating`, and
  `formatBytes{Delta,Ceiling}` lose their last production caller but are
  kept and still tested, annotated with why.
* `projects_store::corrupt_since` and `migration_store::peek_ownerless_since`
  were read only by the disk survey and are removed. The corrupt-load
  marker and `.bak` are still written.

Verified: `npm run test` 611 passing, `npx tsc --noEmit` clean,
`npm run build` green; `cargo test` 419 passed / 2 ignored,
`cargo build` 0 warnings. Every test removed belongs to a removed
feature — no kept-behaviour test was weakened or deleted.

shadow-testandClaude Opus 5 6a8972980d Stop an untouched secret field from deleting the stored credential
Making `null` actually clear a secret — which it had to, since a blanked
token was previously never revoked — turned the config editors into a
credential shredder. Secrets are `#[serde(skip_serializing)]`, so the
inputs always render empty whether or not one is stored, and the blur
handlers sent `value || null` unconditionally. Focusing the Git token
field and tabbing away deleted it, with nothing shown and no undo.

`useSecretField` encodes the rule: only a field the user typed in may
speak about a secret. Untouched, `patch()` contributes no key at all, and
Rust already distinguishes an absent key from an explicit null.

`withoutUntouchedSecrets` covers the structural half. `saveBedrock`
spreads `{ ...bedrock, ...patch }`, and when that falls back to
DEFAULT_BEDROCK_CONFIG the literal spells every secret out as `null` — so
editing the AWS region would have wiped the credentials as a side effect.

Also here: `WorkspaceSection` no longer saves a half-filled folder row,
which `update_project`'s new validation would refuse on every keystroke
between the two inputs; `snapshots_skipped` is declared on the wire type
rather than widened locally; and `#[must_use]` on `ProjectGuard` and
`ScrubOutcome` — which immediately caught the migration path discarding
its scrub outcome, the one scrub whose silence is expensive because the
layer it declined to clean is about to be committed.

The capability test reads the real file and is mutation-verified: adding
`core:default` back makes it fail. That grant pulls in an unscoped
`std::fs::read` of any host path and went unnoticed for months, because
nothing in the suite read the file at all.

shadow-testandClaude Opus 5 f2a84c18f9 Judge a host path by where it leads, not by how it is spelled
`validate_host_path` was a string test. Nothing in the module called
`canonicalize`, `read_link` or `O_NOFOLLOW`, so a path whose components are
all visible could still land somewhere hidden: with `~/Downloads/pub` a
symlink to `~/.ssh`, a `host_path` of `~/Downloads/pub/authorized_keys` has no
hidden component, no `..` and no system root — and writes into `~/.ssh`. The
container end is not hypothetical: `/proc/self/mountinfo` inside a Triple-C
container spells the host's project paths out verbatim, so code in there knows
both where to plant the link and what host path to ask for. The same bypass
read host files back the other way.

So the policy now runs twice: once on the string, and once on what the OS says
the string resolves to. A write resolves the parent and keeps the caller's
leaf, because the leaf is never followed — the partial file is created with
`O_EXCL` and the download finishes with a rename, which replaces a link rather
than writing through it. A read resolves the whole path, because the whole
path is opened. On Linux the descriptor is then checked against the path that
was validated (`/proc/self/fd`), which is what closes the window between
resolving and opening; elsewhere that window stays open and the comment says so.

Also here:

  * The upload's overwrite guard is a guard again. `noOverwriteDirNonDir`
    refuses only dir-over-non-dir and the reverse — file-over-file extraction
    proceeds, which is exactly the `.credentials.json` case (verified against a
    live daemon). The probe and the write are now one `set -C` exclusive
    create, with the path travelling as `$0` rather than as script. The
    `FILE_EXISTS: <path> already exists` contract with the frontend is
    unchanged, and now pinned by a test — as is the claim the old comment made.
  * Windows normalisation stopped being a string swap: `\\?\`, `\\?\UNC\` and
    administrative shares all reach the same places and are compared as such,
    and the rules are pure functions over a string, so the Windows entries are
    exercised on any platform. The old test passed on Linux only because
    `Path::is_absolute` was false for a Windows path.
  * Container write roots are resolved inside the container too, and the
    comment no longer claims more than the check does.
  * A failed download can no longer delete a pre-existing file that happened to
    collide with the partial's name.
  * One-shot exec output is buffered as bytes and decoded once, so a filename
    split across two Docker frames survives; stdout and stderr are tellable
    apart, so `find`'s diagnostics stay out of the listing parser; and a
    directory too big to buffer is described as one.

Claude b49dddab45 Make a blanked project credential actually clear
Handoff from the credential change on `r2/sec`, which landed
`secure::store_or_clear_project_secret` and left a `TODO` naming this
call site. `store_secrets_for_project` could only ever write: a token
blanked in the UI stayed in the keychain, `load_secrets_for_project` read
it straight back onto the project, and the container went on receiving a
credential the user had revoked.

**Not the mechanical switch the handoff describes, deliberately.** Every
secret field is `#[serde(skip_serializing)]`, so the project object the
frontend holds carries no `git_token` key at all — a save from the
Workspace, Runtime or Model section sends the field *absent*, while the
editor that owns it sends `git_token: null` when the user blanks it.
`Option<String>` maps both to `None`, so clearing on `None` would delete
every project secret each time an unrelated setting was changed.
`update_project` therefore takes the raw payload, records which secret
fields arrived as an explicit `null`, and clears exactly those; absent
still means "not mine to touch".

**This commit does not build on `r2/scrub` alone** — it calls
`secure::store_or_clear_project_secret`, which exists only on `r2/sec`.
Verified green against that file: 464 tests pass with `r2/sec`'s
`storage/secure.rs` in place.

shadow-testandClaude Opus 5 dcd2dfe5a3 Stop a project id from steering a Docker API DELETE, and stop trusting a store that lost its list
C-2 (critical). `destroy_ownerless_rollback_pin` validated its tag and not its
project id, then interpolated both into `triple-c-snapshot-{id}:{tag}` and handed
the result to bollard. bollard does not percent-encode: `Uri::parse` joins an
absolute path onto the base URL, which replaces the path outright and applies RFC
3986 dot-segment removal. An id of `a/../../v1.47/volumes/<name>?` turns a
"remove image tag" into `DELETE /v1.47/volumes/<name>`. That arm is reached
*because* `find_project` failed, so the id is unconstrained IPC input, and the
typed confirmation is no barrier — it compares the caller's own two strings.

Reproduced against the live daemon, and now a test: with the check removed the
volume is gone and the test fails; with it, the volume survives and a legitimate
ownerless pin still deletes. The reference that reaches `remove_image` is now the
daemon's own repo_tag, matched on the parsed pair, so nothing built from IPC
input addresses the API at all. The same id check now guards the owned arms of
`destroy` and `compact_snapshot`, which build volume names and image references
from a `projects.json` field.

H-1. The ownerless arm decided ownership from the in-memory list alone and then
called `sweep_orphaned_snapshots()`, which deletes the freshly dangling image on
the same pass — so a corrupt `projects.json` could reap a pin whose migration is
still awaiting confirmation, the one thing `pin_is_reapable` orders its
conditions to prevent. It now re-reads the store from disk, runs
`project_store_trust`, refuses an id the store knows, takes the project lock
before reading anything a decision rests on, and checks `has_record`.

H-3. The corrupt-store guard keyed on "empty list + file exists", and
`ProjectsStore::new()` swallows a corrupt file without rewriting it — so the
first `save()`, as little as starting a project, wrote `[{new}]` over it and the
guard passed with every other project's volumes unclaimed. A corrupt load is now
recorded in a sticky `projects.json.corrupt` marker beside the file, and the
existing `.bak` is no longer clobbered by a second corruption. A missing
`projects.json` is refused too: it cannot be told from a moved or partially
restored data directory, and the genuinely fresh case has nothing to find.

Also: the three migration commands surface the lock's real refusal instead of
substituting "a migration is already running"; `note_ownerless_since` re-checks
`has_record` after writing a tombstone, closing the window that could plant one
behind a valid record and reap the pin with zero grace; corrupt migration-record
copies are capped at four; `reconcile_migration` yields to any lock holder, not
only a migration; and a 22-space run in a refusal string is gone.

Claude 6d27f924ff Stop the scrub emptying a mount that is itself a glob match
The parent checks in `snapshot_scrub_script` validate the directory a
pattern is anchored to, and `rm --one-file-system` compares against its
own command-line argument's device — so with the mount planted *at* the
match there was nothing between the scrub and the mounted filesystem.
Verified against a live daemon with the byte-identical generated script:
mounted at the parent (`/var/log/apt`) refused, mounted one level below
(`/tmp/claude-x/inner`) refused, mounted as the match (`/tmp/claude-x`)
came back with the volume empty. The same run against a host directory
bound at `/workspace/../tmp/claude-x` — the target the daemon builds from
a mount name of `../tmp/claude-x`, confirmed through the API bollard uses
— emptied the host directory.

Each match is now checked against the root's device too, which for a
directory whose parent has already been validated is exactly a
"not a mount point" test. A symlinked match still reports the link's own
device, so `rm -rf -- link` goes on unlinking it and stopping.

The tools are also named absolutely and `PATH` is reset. The image's
`PATH` starts with three directories inside the container's persisted
home volume, and a three-line `stat` shim planted in the first of them
made the previously-refused `/var/log/apt` mount delete its contents.
"Missing `stat` fails closed" was true and beside the point.

`update_project` validated nothing while `add_project` validated its
folder list, so the mount name that reaches all of this was one
save-on-blur away from anything at all. Both now share
`validate_project_paths`, which also refuses `..`, a filesystem root as a
host path, and a half-filled row; `container_id`, `status` and
`created_at` are no longer writable through a project save.

`remove_project` was the only writer of a container, a snapshot image or
a volume that took no project claim (H-2), so removing a project during
a compaction let `restore_image_config` commit a flat image back over
`triple-c-snapshot-{id}:latest` for a project that no longer exists —
invisible to every reclaim path. It takes `ProjectOp::Destroy` for the
whole removal; the sidebar row survives a refusal because it is only
dropped after the command resolves.

Finally, a commit whose scrub was skipped no longer logs "0.00 MB
dropped", which every migration did.

shadow-testandClaude Opus 5 e70a40507c Stop granting an unscoped host-file read, and make a refused credential scrub recoverable
`core:default` was an alias for nine core plugins' default sets, and one of
them — `core:image:default` — carries `allow-from-path`, whose handler is a
bare `std::fs::read(path)` with no scope mechanism at all. Nothing imports
`@tauri-apps/api/image`, so the plugin is dropped rather than scoped; there is
nothing to scope it with. The capability file now enumerates what `app/src`
actually invokes, which is `core:event`'s listen/unlisten and nothing else from
core — every emit in this app originates in Rust. `core:menu`, `core:tray`,
`core:window`, `core:path`, `core:resources` and the three dead `dialog:`
grants go with it. `core:webview:allow-internal-toggle-devtools` stays because
Tauri's own injected debug script calls it; both it and the command behind it
are `cfg(any(debug_assertions, feature = "devtools"))`, so it is absent from a
release bundle. Verified empirically: an unknown identifier fails the build, so
every identifier kept is real and the regenerated `gen/schemas/capabilities.json`
carries the opener scope verbatim rather than silently dropping it.

`opener:allow-open-url` cannot be host-narrowed — the terminal opens links
Claude printed inside the container — so what it does and does not buy is
recorded instead, including the verified fact that each scope entry's `app`
defaults to `Application::Default`, which matches only `with == None` and
therefore refuses `openUrl(url, "/bin/sh")`.

`clear_claude_token` deleted the keychain entry first and swept the snapshot
images second. The sweep runs once and skips a project another operation holds,
the deleted entry made `has_claude_token` false, and Revoke rendered only while
a token was stored — so a project that happened to be starting during a revoke
kept a live ~1-year OAuth token in its snapshot's `Config.Env` permanently,
with Reset (which destroys both volumes) as the only remaining remedy. The
sweep now runs first, so a crash mid-revoke leaves the app still saying
"authenticated" with the same button still able to finish; a busy project is
reported as `snapshots_skipped` rather than folded in with images that genuinely
cannot be rewritten; and the panel keeps a retry visible independent of token
status, plus offers the sweep outright when nothing is stored, because a
snapshot committed by an older build carries the token either way. The retry is
the same command — it is idempotent, and the images are the durable record.

Also: `openai-compatible-api-key` was written but never deleted, so it outlived
its project. The key list is now the single definition and an unlisted key is
refused outright, so the writer cannot get ahead of the deleter again.

`store_or_clear_project_secret` lands here unused on purpose: the editors send
a blanked field as `null` and `store_secrets_for_project` skips `None`, so
clearing a secret through the UI is impossible today. Its one call site is in
`commands/project_commands.rs`, which belongs to another change in this round.

No `devCsp` was added. `tauri dev` loads the main document straight from Vite,
and Tauri only attaches a CSP to documents it serves itself — the dev server is
proxied through `tauri://` only when `PROXY_DEV_SERVER`, which is
`cfg!(all(dev, mobile))`. A `devCsp` here would be inert config that reads as
protection. The reasoning, and the one place that could set one, are recorded.

shadow-testandClaude Opus 5 4f6c012071 Make a rollback pin outliving its project visible and deletable
`survey_rollback_pins` walks images, not projects, and deliberately
tolerates an absent project by falling back to the raw id as the display
name. Two things then dropped it on the floor: `destroy` called
`find_project` before the confirmation check, so it refused such a pin
every time, and the per-project table joins destructive items to rows by
project_id, where rows come only from projects in the store. The result
was a multi-GB `pre-migration-*` image that the scan measured, the panel
never rendered, and nothing could remove — in the one screen built to
find exactly that.

`destroy` takes the same early return `OrphanVolume` already takes, and
still validates the tag: `latest` names the project's live snapshot, so
the ownerless path must not be a way around that check.

The UI grows a bucket for destructive items matching no row, rather than
filtering them away. The typed gate already compared against the id via
`project_name`; the dialog now says "project id" instead of asking for a
project name that no longer exists.

shadow-testandClaude Opus 5 a76f2c0a17 Close the cross-stream gaps the parallel fix round left open
Three items each of which fell between two agents' file lists.

`scrub_secrets_from_snapshots` was the third unsynchronised writer of
`triple-c-snapshot-{id}:latest`, after a recreate's commit and a
compaction. It has the same read-modify-write shape — create a scratch
container from the snapshot, commit back over the same tag — and loses
the same race, which here means re-baking the very credential it exists
to remove. It now takes the project's claim, under a new
`ProjectOp::SecretScrub`, and reports a snapshot it had to skip rather
than rewriting it unsafely.

Its scratch container also now carries `triple-c.scrub=true`, so the
Disk panel's reclaim bucket discriminates by label and by the live claim
rather than by a clock. The 15-minute age gate stays as the backstop for
the cross-process case the claim cannot see.

The store plugin is unregistered and its dependency dropped. Its
capability grants were removed as a host-file-write primitive; the
registration without a grant was unreachable but dead.

Finally, container.rs's fold test was pinning a fold that no longer
exists — disk.rs now emits the JSON exec form. It asserts the stronger
property instead: the script a compaction runs is byte-for-byte the one
snapshot_scrub_script() produces, so the two files cannot drift silently.

shadow-testandClaude Opus 5 6abc7f27a4 Fix disk/migration defects and add a real per-project lock
The compaction panel's headline action had never worked, three reclaim
paths could delete data with no confirmation and no grace period, and the
app's only mutual-exclusion primitive was one-way.

**A per-project lock (`project_lock.rs`).** `ACTIVE_MIGRATIONS` was the
app's only exclusion and everything but migration merely *polled* it once
at entry. Compaction, start/stop/recreate, Reset and destroy now
**acquire** a `ProjectGuard` and hold it for the whole operation;
`is_migrating` is a view onto the same registry. Closes the three verified
interleavings where a compaction commits `flat(A)` over a `:latest` that a
migration, a recreate or a Reset had already moved. In-process only — the
two-instance case is documented in the module, not solved, and the
daemon-wide reapers gained age gates to bound it.

**H1: compaction never ran.** `fold_shell_script` joined the scrub script's
lines with a space, so every build died on `syntax error: unexpected "do"`.
Replaced with the JSON exec form, which carries any script verbatim;
`sh -n` and a real end-to-end build now cover it (159.5 MB / 9 layers ->
33.7 MB / 1 layer, setuid and multi-line env preserved).

**H2/H4:** `reclaim_migration_pins` and `survey_rollback_pins` apply
`parse_rollback_tag` and `pin_is_reapable` like every other path, and stop
double-counting an image with two pin tags. The 14-day grace period is
re-anchored from the tag's timestamp (when the migration *started*) to a
tombstone recording when the record went missing, with clock skew handled
in both directions.

**H3:** `migration_store::load` no longer renames a corrupt record aside —
that destroyed the `has_record` signal both pin reapers depend on. `save`
fsyncs the file and the directory, and corruption backups are timestamped.

**H2b/M2:** a crashed compaction's `:compacting` tag and `triple-c-compact-*`
container are reaped at startup; the stale-container sweep moved from the
end of a compaction to the start, where its doc always claimed it was.

**M5/M6:** orphan-volume deletion moved from a `Safety::Safe` tick to the
destructive path with a typed volume name; `project_store_trust` reads the
real `projects.json` so a second instance's project is not offered as an
orphan.

Numbers: `images_total_bytes` uses `df()`'s deduplicated `layers_size`; the
Total column is derived from the same figure the Snapshot column shows;
partial container/staging reclaims report their failure count; `human()`
no longer prints "1000.0 KB"; `docker_cli` has a timeout; blocking `fs`
calls moved to `spawn_blocking`.

Also fixes `ProbeContainerGuard::remove_now`, which disarmed before the
await and so did nothing on the cancellation path it exists for.

shadow-testandClaude Opus 5 3329e07d3d Fix the file command surface: argument injection, unbounded reads, unchecked paths
`list_container_files` could delete the user's files. It builds
`["find", path, "-mindepth", …]`, and GNU find ends its starting-point
list at the first argument beginning with `-`, so a `path` of `-delete`
gave it zero starting points (defaulting to `.`, which for an exec that
sets no working_dir is the container's WorkingDir — the bind-mounted
project) and an expression starting with `-delete`. Verified against a
live container on findutils 4.10.0: files and empty directories went out
of the host bind mount, and because `exec_oneshot` discards the exit
code the panel then reported an empty folder.

The rest of the module had the same shape of hole:

* Every path parameter — `path`, `from_path`, `parent_path`,
  `container_dir`, `container_path`, `host_path` — arrived over IPC
  unchecked. There is now one validator for container paths (absolute,
  no `..`, no NUL, length-capped), a second for the ones that *change*
  something (contained in /workspace, /home/claude or /tmp), and one for
  host paths, which refuses traversal, system locations and hidden
  components. The `save()`/`open()` dialog in front of these commands is
  a UI convention, not a boundary.

* `download_container_file` passed `None` for the fetch cap, so the cap
  was inert: the whole transfer was buffered in host RAM twice, and the
  directory refusal came *after* the buffer, so `/` meant buffering the
  container's filesystem before erroring. Downloads now stream through a
  bounded channel into the tar reader, which refuses a non-regular entry
  and an oversize one before the host file is created at all. Verified
  against a real container: a 300 MiB download peaks at 10 MiB RSS, a
  9 GiB sparse file is refused in 0.01s with nothing written.

* Both download paths (file and backup) used to create — i.e. truncate —
  the user's destination up front and delete it on a stream error, which
  is precisely the wrong order for a path that already holds something.
  They now write beside it and rename on success.

* `upload_file_to_container` silently clobbered: no existence check
  anywhere in the stack. It now refuses by default with a FILE_EXISTS
  marker the frontend turns into a Replace/Skip prompt, and takes an
  `overwrite` flag for the retry.

* `exec_oneshot_inner` read an undeterminable exit status as 0, so
  rename and mkdir reported success for an exec nobody could read the
  outcome of. It fails closed now.

* A tab in a filename forged the type/size/permission columns of a
  listing row, and a newline forged a whole row. `find` now prints the
  name last with NUL-terminated records.

While verifying the size ceiling against a real container, the tar
header's size field turned out to be unusable past ustar's 8 GiB octal
limit — Docker's Go writer puts the real size in a PAX record — so both
readers take it from `entry.size()` instead.

shadow-testandClaude Opus 5 092972fe92 security: close capability, CSP and auth-bridge holes
capabilities/default.json
- Drop every `store:*` grant. `@tauri-apps/plugin-store` has no caller in
  `app/src`, and the plugin's `resolve_store_path` is a `PathBuf::push` against
  AppData — `push` discards the base for an absolute path, so the grant was an
  arbitrary host read/write from the webview.
- Replace `opener:default` with a scoped `opener:allow-open-url` (http/https
  only). That drops `reveal_item_in_dir`, which the plugin does not scope-check
  and nothing here calls, and the unused mailto:/tel: scope.
- Record the unscopable `drag:allow-start-drag` residual risk in `description`.

tauri.conf.json
- Add `form-action 'none'`, `base-uri 'none'`, `object-src 'none'`.
  `form-action` has no `default-src` fallback, so an injected auto-submitting
  form was unblocked even though `script-src 'self'` blocks XSS.
- Remove the dead `asset:` / `https://asset.localhost` img-src and `data:`
  font-src grants; `blob:` stays (the file viewer uses it).

auth_bridge
- The reserved-port set covered only this project's mappings and the two
  browser-view ranges. It now also covers the gateway, STT and web-terminal
  host ports (configured value and shipped default, read off the settings
  models) and every other project's published host port. A container binding
  container-loopback 4000 / 9876 / 7681 while those services were stopped had
  that port mirrored onto the host, unauthenticated, within one poll.
- Gate the host listener on fetch metadata: refuse a request that is a
  cross-site sub-resource, allow navigations (the OAuth redirect) and anything
  without `Sec-Fetch-*`. Non-HTTP connections are classified from their first
  line and forwarded verbatim. Residual risk is spelled out in the module docs.
- Bound the forwards: max concurrent connections per port, a first-byte
  deadline enforced before any `docker exec` is created, and an idle timeout.

browser_view/mod.rs
- `pick_viewer_port` reads procfs with `/usr/bin/cat`, not a bare `cat` the
  container can shim via its writable PATH entry.
- Treat port choice as check-then-bind: walk to the next free candidate when
  the viewer does not come up, instead of failing the start.

BrowserTab.tsx
- Sandbox the viewer iframe. Container-controlled content could `top.location`
  the app's webview away. `allow-top-navigation*` and
  `allow-popups-to-escape-sandbox` are deliberately absent.

HelpDialog.tsx
- Escape the quote characters in the entity pass and escape captured attribute
  values. `href="$2"` with `$2` = `[^)]+` let remote GitHub markdown close the
  attribute and open another, in a document rendered with
  `dangerouslySetInnerHTML`.

web_terminal/terminal.html
- SRI hashes plus `crossorigin` on the three jsdelivr bundles and the
  stylesheet, and a CSP for the page — it is served 0.0.0.0 behind a permissive
  CORS layer and nothing else gives it one.

Claude ae3ca8cda4 Fix root scrub deleting host files through symlinked parents (C1)
SNAPSHOT_SCRUB_PATHS is expanded by /bin/sh inside the container as root.
For an entry ending `/*` the parent is a path *component*, resolved by both
the glob expansion and the `rm -rf`. The agent has passwordless sudo, so
`ln -s /workspace/myproject /var/log/apt` turned the next commit into a
recursive delete of the user's real files on the host — reproduced end to
end against a live container.

snapshot_scrub_script now routes every deletion through one `scrub_in`
function that validates the parent before touching anything inside it:
`cd -P` for a TOCTOU-free handle, `pwd -P` equality to reject a symlinked
component, a hardcoded containment allowlist that is deliberately not
derived from the path list, and an st_dev comparison against `/` so a bind
mount or a volume is refused even though it is not a symlink. It fails
closed when `stat` is missing.

Also:
- /tmp/triple-c-drops/* and /tmp/clipboard_*.png are age-limited to 14 days
  instead of scrubbed unconditionally. They hold the user's own files, and
  scrubbing them meant "drop a file, change a setting, lose it silently";
  removing them from the list would restore unbounded growth instead.
- M11: scrub_writable_layer returns a ScrubOutcome and skips cleanly when
  the container is not running, so a migration no longer logs "could not
  run … committing anyway" on every run.
- M12: the scrub exec is bounded by a 120s timeout; on expiry it logs and
  lets the commit proceed.
- The script is now fold-safe (self-terminating lines, no `#` comments).
  disk.rs folds it onto one `RUN` line and the previous form was a
  `"do" unexpected` syntax error there, so compaction had been scrubbing
  nothing at all.

Tests: the substring check on the script text is replaced by a behavioural
test that runs the real generated script with a real symlink planted in a
throwaway tree, plus structural tests over each containment construct and
a `sh -n` check of the folded form.

  pin". It is the one destructive variant carrying a free-form string, so
  it now goes through `parse_rollback_tag`.
- The compaction's scratch container was named `triple-c-scrub-*`, which
  is what the scrub reclaim bucket hunts and force-removes. A reclaim from
  a second window would have destroyed the container a running compaction
  was about to commit. It gets `triple-c-compact-*`, swept at the start of
  the next compaction rather than from a bucket anything else can fire.
- Deleting a home or config volume only refused a *running* container, but
  a stopped one still pins its volumes — the resting state of every
  project ever started — so the user typed the project name and met a raw
  409. The container is now removed first and `loses` says so.

Correctness:

- The compaction Dockerfile emitted no `LABEL`, so the flattened
  intermediate could never match the sweep's `dangling` + `triple-c.managed`
  filter that three cleanup paths rely on. Verified on Docker 29.7.2 that
  the label lands on the final stage, the build still yields one layer, and
  untagging the staging tag after the commit leaves the committed snapshot
  intact and startable.
- `snapshot_commit_layers` silently meant something else when
  `triple-c.base-image-id` was absent — the normal case for a pre-label
  project — counting the base's own layers and letting a never-recreated
  project qualify for compaction. `base_lineage_known` now carries that,
  the column says "unknown", and the plan does not offer the rewrite.
- `destroy` returned a `ReclaimResult` wearing a `ReclaimTarget` that named
  work it had not done (a home-volume deletion came back as
  `OrphanVolume`). Split into `target` / `destroyed`, exactly one set.
- `formatBytes` ran `toFixed` after the divide loop, so 999,999 rendered as
  "1000.0 KB" — in the app's only byte formatter, in a panel full of
  near-boundary sizes.
- `is_base_image_reference` split on the first colon, so a registry port
  ate the repo name.

UI:

- `snapshot_above_base_bytes: null` — deliberately unmeasurable — rendered
  as "0 B", the one guessed number in the table.
- Layer count was flagged by colour alone; it now says "stacked".
- The tick list survived a reclaim, so the same call could be re-fired at
  objects that no longer existed. The plan is dropped after any action and
  the panel says the totals predate it.
- `setReport` landed before the plan call was awaited, so a plan failure
  rendered fresh totals above the previous scan's rows.
- Both confirmation modals unmounted before awaiting, making the entire
  busy path dead code during multi-second work.
- `buildx du` failures silently showed `docker system df`'s under-reported
  build-cache figure with no explanation.
- Tooltip text reached no assistive tech, so two headers announced as
  "Help"; hardcoded input id; error-toned glyph in warning-toned panels;
  `sweepOrphanedSnapshots` and `clearOutcome` had no callers.
- Four docstrings claimed things the code did not do, and two tests were
  named for behaviour they did not assert.

Tests: 513 frontend (was 502), 370 Rust (was 365).

shadow-testandClaude Opus 5 77ef2291d7 Add a Disk section: see where the bytes went, and get them back
Every recreation runs `docker commit`, which stacks a layer and never
rewrites one, and 24 conditions in `container_needs_recreation` trigger a
recreation. Prevention landed earlier on this branch; this is the half a
user can act on.

The per-project table leads with the two numbers that explain the
mechanism rather than just the total: how many commit layers a snapshot
has stacked above its base, and what the container's writable layer will
add at the next commit.

Backend (`docker/disk.rs`, commands in `docker_commands.rs`):
- `get_docker_disk_usage` — one `df()` joined against the project store,
  behind an explicit Scan button because it walks the whole daemon.
- `list_reclaimable` / `reclaim` — classified buckets with measured bytes,
  planned off the existing report so re-planning costs no second scan.
- `destroy_project_disk_object` — one object, typed confirmation.
- `sweep_orphaned_snapshots` — exposed, so its report is finally visible.

Safety is structural: `reclaim` takes `ReclaimTarget`, which has no
variant that can name a live project's data. Destructive work is a
separate type reached only through `destroy`. No unfiltered prune is
called anywhere, and nothing outside a `triple-c*` name or `triple-c.*`
label is touched.

Orphan detection subtracts ids from the project store and consults
nothing else. From the daemon's side an idle live project and a deleted
one are indistinguishable — volumes present, no container, no image — so
inferring from container or image absence would offer a live project's
credentials and transcripts for deletion. A store that loaded empty from
an existing `projects.json` is treated as a failed load, not as "no
projects", because `ProjectsStore::new()` recovers from a corrupt file by
starting empty.

Three things verified against a live Docker 29.7.2 rather than assumed:

- Compaction is a two-stage build (`FROM scratch` + `COPY --from`), which
  keeps every byte inside the daemon; bollard's import buffers a whole
  image into memory. uid/gid and setuid survive; a 192.6 MB/4-layer
  synthetic came out 45.7 MB/1 layer. Image config does not survive, so it
  is replayed via create+commit, which round-trips a multi-line env var
  that a Dockerfile `ENV` could not.
- Flattening breaks base-layer sharing, so the result carries its own copy
  of the base. Eight of ten real projects had a 0.10–1.32 GB delta over a
  4.72 GB shared base — compacting those costs ~4 GB. The bound now
  subtracts that penalty, such projects are not offered at all, and the
  run compares unique bytes and abandons a rewrite that would grow.
- `docker builder prune` reports `Total:`, not `Total reclaimed space:`,
  so the first parser scored every prune as freeing nothing.

The Windows/WSL2 note is mandatory and its copy lives in Rust beside the
tests that pin it: pruning frees space inside `ext4.vhdx`, which never
shrinks on its own, so C: does not change until the disk is compacted.

Also adds `lib/formatBytes.ts` — the app had four disagreeing copies, and
`projects/home/format.ts` and `migrationCopy.ts` now delegate to it with
byte-identical output. Base 1000 by default, matching what Docker prints.

Tests: 502 frontend (was 453), 365 Rust (was 322).

shadow-testandClaude Opus 5 1c834a0b08 Drag a file out of the Files tab onto the host desktop
The Files tab could accept a drop but never produce one: getting a file
out meant "Save to host…" and a file picker. This adds the other
direction.

Two constraints shape it. `dragDropEnabled` is on — TerminalView needs
it, since the native drag-drop event is the only one carrying dropped
file paths — and it blocks HTML5 drag inside the webview, so `draggable`
plus `DataTransfer.setData("DownloadURL", …)` was never available. The
gesture is therefore pointer events into `tauri-plugin-drag`, the same
shape and the same reason as the tab strip's drag. And the file being
dragged does not exist on the host at all: it lives in a container, and
the OS can only drag a real host path.

So a drag-out is a copy first and a drag second.
`stage_container_file_for_drag` materialises the file into
`<os-temp>/triple-c-drag-out/<session>/<slot>/<name>` through the same
`fetch_container_file` the download and the viewer use, keeps the
original filename (a dropped `tmp1234` is not a file anyone wants), and
caps at the 256 MiB an upload already caps at, naming "Save to host…" in
the refusal. The path comes from Tauri's path API rather than `/tmp`,
because on Windows it is neither.

The staging directory has a lifecycle, because whole files accumulating
in the host temp dir would be the disk problem this project just fixed,
in a new place: cleared on exit inside the existing teardown (still
guarded on the main window), and reaped at startup for whatever a crash
left behind.

The copy is also an async gap in the middle of a gesture that feels
instantaneous, and the OS only adopts a drag while the button is still
down. Small files beat the pointer; large ones do not — so the staged
path is cached per entry (keyed on size and mtime, so an edited file
re-stages) and the pane says the copy is ready and to drag again, which
is an instruction rather than an apology because the retry is immediate.
A per-file slot keeps `a/notes.txt` and `b/notes.txt` from becoming the
same host path.

"Save to host…" stays exactly as it was. Drag-out is the enhancement;
a platform that refuses `startDrag` says so and points back at it.

shadow-testandClaude Opus 5 0a022dfcf0 Let a project turn a globally-enabled Claude Code setting back off
The six boolean settings were plain `bool`s merged with
`if p.x { true } else { g.x }`, so a project could only ever add to the
global set. There was no project value that produced `false` — turning a
switch off at project level simply fell through to the global value and
the control did nothing.

Widen them to `Option<bool>`. `None` means "not set at this level":
inherit the global on a project, leave Claude Code's own default alone
globally. `Some(false)` is a deliberate off and wins outright.

The fingerprint now formats with `{:?}` rather than `{}` — `None` and
`Some(false)` mean different things, and conflating them would leave the
container un-recreated when a project switched from inherit to off.

The project editor grows a third "Global" state per switch; the global
editor has nothing to inherit from, so it stays a plain toggle and keeps
collapsing to null at the default. Its three existing tests passed
unchanged and caught a first attempt that rendered unset as off, which
would have told every user their session recap was disabled.

shadow-testandClaude Opus 5 bb41275cea Keep the managed settings payload safe for un-migrated projects
The null-means-delete convention is only understood by the entrypoint.sh
shipped alongside this code. An existing project recreates from its own
snapshot image, which carries whatever entrypoint it was built with, and
an older one merges with a plain `.[0] * .[1]` — so the literal nulls
would land in the user's settings.json rather than clearing the keys.
Verified against jq: that produces `"tui": null, "effortLevel": null,
"viewMode": null, "awaySummaryEnabled": null`, risking the whole file
being rejected and taking the user's own `model` and `statusLine` with it.

Split the payload instead. CLAUDE_CODE_SETTINGS_JSON now carries only
keys that have a value and is safe under either merge; the new
CLAUDE_CODE_SETTINGS_CLEAR carries the key names to delete and is
ignored by an entrypoint that predates it. Such a project keeps the old
sticky behaviour until it is migrated or Reset, which is the
pre-existing state rather than a regression.

shadow-testandClaude Opus 5 2ca86bb5d8 Scrub the writable layer on the migration path too, and de-duplicate CLAUDE_JSON
Two integration fixes after merging the three feature branches.

`scrub_writable_layer` is a `docker exec`, so it only works while the
container runs. `migrate_project_to_base` stops its container one line
before the pre-swap commit, which meant the single largest snapshot
Triple-C ever takes was the one path that committed unscrubbed. Call the
scrub explicitly before the stop instead of relying on the call inside
`commit_container_snapshot`.

Also drop a duplicate `CLAUDE_JSON=` assignment in entrypoint.sh. The
Shift+Enter block re-declared it defensively to avoid a merge conflict
with the awsAuthRefresh block; the conflict did not materialise.
