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.

shadowdaoandClaude Opus 5 f7db4323be Make the drop gate a state question, not a geometry one
The gate that decides whether a native file drop is accepted has been wrong
twice in opposite directions, both times because it tried to be precise about
*which points* a dialog covers:

- Round 1 asked `el.contains(elementFromPoint(x, y))` and was handed the inner
  xterm host while the overlays are siblings, so the always-rendered
  Following/Paused button made the terminal's top-right corner permanently
  refuse drops.
- Round 2 replaced that with "is a blocking overlay painted here?" and deleted
  the document-wide gate. `elementFromPoint` returns the *topmost* element, and
  ToastHost is z-[60] against the Modal backdrop's z-50 in the same stacking
  context — so a refused drop pushed a toast, the toast covered the dialog, and
  the next drop released on it was reported clear and landed in the directory
  the dialog was covering. The gate armed its own hole.

Split the two questions instead of merging them:

- Geometry answers *whose* drop it is (rect hit test, unchanged), so exactly
  one listener speaks for a drop and a hidden pane's zero-size rect still keeps
  TerminalView and FilesTab from both firing.
- `dropIsBlocked` answers whether the app should take a drop at all —
  document-wide, no z-index in it. While a modal or blocking overlay is on
  screen anywhere, every drop is refused.

There is no `elementFromPoint` call left, so no future overlay can become a
drop hole by being painted high enough and no chrome can become a dead zone by
being painted at all. The cost is over-refusal while a dialog is open, in a
state the user entered deliberately, announced, writing nothing.

Also:
- `[aria-hidden="true"]` no longer disqualifies a blocker. It is not a
  visibility statement (it sits on visible decorative content), so a blocker
  nested in such a wrapper would have silently stopped blocking.
- Modal drops `data-blocks-drop` when its pane hides, and moves focus out of
  itself rather than leaving it inside a `display:none` panel.
- The refusal notice stays `kind: "info"` (an expected refusal is not an
  error, and an error card never auto-dismisses) and carries a `dedupeKey`, so
  repeated refusals replace rather than stack.

Tests: mutation-checked against the previous implementation — four in
dropTarget.test.ts, two in each of TerminalView/FilesTab, two in Modal.

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 5926a52ff6 Stop the terminal and Files panes refusing drops onto their own chrome
The z-order gate added last round asked `el.contains(elementFromPoint(x, y))`
— "is the thing painted here mine?" — and was handed `TerminalView`'s inner
xterm host while every overlay in that pane is a *sibling* of it. So any point
under the pane's own chrome answered "not mine" and the drop was refused, with
no message and no log line. The "▼ Following / ▽ Paused" toggle is rendered
unconditionally at `absolute top-2 right-4`, and `ToastHost` is `fixed
bottom-4 right-4` 24rem wide with error cards that never time out: two corners
of the terminal, and one of the Files pane, that could not accept a file for
as long as the app was running.

It shipped green because jsdom has no `elementFromPoint`, so not one of the 81
drop tests entered that branch. The tests here install one.

The question the gate asks is now "is a *blocking overlay* painted here?".
Chrome the pane paints over itself is not one; a dialog backdrop is, and
`ui/Modal` marks its own backdrop so the element `elementFromPoint` actually
returns is the one carrying the marker. `classifyDrop` also separates "aimed at
me and swallowed" from "not my drop", so the first gets a toast and a log line
and the second stays silent.

Three defects around it:

- **A dialog now refuses only the points it covers.** `dropIsBlocked` is
  document-wide and `ui/Modal` portals to `document.body`, so any open dialog
  refused every drop in the window. The deeper half of that is that a dialog
  opened in project A really was still on screen after a tab switch — the pane
  hides itself with a `hidden` class, which a portal does not inherit — so
  `PaneVisibility` lets `App` tell a `Modal` its pane stepped aside, and a
  hidden one paints nothing, traps no focus, answers no Escape and blocks no
  drop while staying mounted with its state intact.

- **`devicePixelRatio` is applied on Windows only.** Only wry's WebView2
  backend hands over physical pixels; the macOS and GTK ones deliver logical
  points and `tauri-runtime-wry` does not rescale them. Halving those was
  survivable while the test was a bare rect and is a refused drop once z-order
  joins in. Read from the wry/tauri sources, not verified on a HiDPI Mac or
  GTK box.

- **`isFileExistsError` can no longer be forged by a filename.** It matched
  `fileexists` anywhere in a normalised error, so uploading a host file called
  `file-exists.txt` turned *any* failure into a collision — and Replace
  re-invoked the upload with `overwrite: true`. The marker now has to stand
  alone in the backend's canonical form, or be a whole discriminant value.

- **A refused compaction or cache-clear keeps its dialog.** `reclaim` reports
  refusals inside `Ok`, so "did it throw" read one as success: the dialog
  closed, the tick list was dropped, and the explanation appeared in the
  outcome panel several screens above the row that was clicked. The dialog now
  stays put and renders the backend's own sentence verbatim.

changes, unmentioned in its message. Second time this session that
`git add -A` has staged something unrelated — ignore the pattern so it

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-test 6b8d43414d Merge branch 'fix/reconcile' into integration/round-1 2026-08-23 12:13:55 -07:00
shadow-testandClaude Opus 5 1768240861 Unstick a project row whose lifecycle command was refused
Two more pieces of drift from the same merges, both invisible to `tsc`.

**A refused Start/Stop/Reset strands the row.** `start`, `stop` and
`rebuild` paint an optimistic "starting"/"stopping" so a click moves the
row at once. That was safe while the only way these could fail was after
the backend had begun changing things. `fix/sec`'s per-project lock ended
that: all three now take the lock and are refused *before* any state
changes, and `stop` could not fail this way at all before — it took no
exclusion. So the optimistic paint has nothing to become, `isTransitioning`
disables both Start and Stop, and the only thing that clears it is
`reconcileProjectStatuses`, which runs once from `App.tsx` when Docker
first appears. Clicking Stop during a compaction left the project
unusable until the app was restarted.

`withOptimisticStatus` re-reads the authoritative list when the command
throws, and falls back to the status that was on screen if even that call
fails — two failures in a row must not land on the one state there is no
way out of. The error is rethrown unchanged, so the toast is unaffected.
Five of the six new tests fail against the previous code; the sixth pins
that the optimistic paint still happens on the way in.

**Six secrets are typed as if they arrive, and they never do.**
`git_token`, the four Bedrock credentials and `OpenAiCompatibleConfig
.api_key` are `#[serde(skip_serializing)]` in Rust, so the key is absent
from every project the backend returns — reading one gives `undefined`,
not the `null` the type promised. Every current reader happens to use
`?? ""`, so nothing is broken today; a single `=== null` would have been a
branch that silently never ran. They are optional now, which makes that a
compile error, and documented as write-only, which is what they are.

669 frontend tests pass, `tsc --noEmit` clean, `npm run build` green.
Nothing under `src-tauri/` touched.

shadow-testandClaude Opus 5 7e1f8df1ff Reconcile the frontend with the round-1 backend contracts
Five backend branches merged and the TypeScript still compiled, because
none of this is a type error: a field that arrives `undefined`, a variant
nothing emits any more, a prompt whose loop never closes. Six things.

**Orphaned volumes are destructive now, not safe.** `ReclaimTarget::
OrphanVolume` is gone from Rust; the object is a `DestructiveTarget::
OrphanVolume { name, project_id }` confirmed against the *volume's* name,
there being no project to name. The TS union still listed it under
`ReclaimTarget`, and — worse — `DiskProjectTable` keys destructive items
off `project_id`, which an orphan's never matches. So the item existed in
the plan and appeared nowhere on screen. `DiskSettings` now splits the
plan's destructive list and gives orphans their own section with a
per-volume `TypedConfirmModal`. The copy says what a
`triple-c-claude-config-*` volume actually is — a Claude login
credential, every plugin and skill, every transcript that project had —
and keeps the sentence explaining that "no matching project" is a lookup
against the project list and is never inferred from a project being
stopped or having no image, which is the inference that once flagged two
live projects.

`TypedConfirmModal` grew a `subject` prop: asking a user for "the exact
project name" of a volume that has no project is asking for a string that
does not exist.

**Snapshot and Total reconcile.** `ProjectDiskRow.snapshot_attributed_bytes`
is the single figure `snapshot_attribution()` exists to produce. The
column rendered `snapshot_above_base_bytes` and fell back to `—` while
the Total was `size - shared` regardless — and in that branch `size -
shared` is the whole 4.7 GB base image, charged per project and then
added again as a base-image row. One field, one rule. The one branch
where the figure *is* the whole image says so rather than passing itself
off as a share.

**The overwrite loop closes.** Traced end to end: a `FILE_EXISTS:`
refusal raises the prompt, Replace re-invokes with `overwrite: true`,
Skip advances, "…all" answers the rest without asking, and picker and
host-drop both reach `uploadFileToContainer` through `uploadPaths`. Two
gaps: a second batch's `askOverwrite` overwrote the first's resolver,
leaving that batch awaiting an answer no dialog could produce; and the
backend's written refusals — a hidden host folder, a path outside the
write roots — were passed as a toast `detail`, which `ToastHost` renders
as collapsed monospace behind a "Details" button, so the only sentence
that explained anything was the part nobody saw. `readableRefusal`
promotes it to the headline when a batch failed the same way.

**The browser pane's sandbox is pinned.** `allow-same-origin` must stay
(the proxy's gate reads `Origin`/`Referer`, and an opaque origin sends
`null`); every top-navigation grant and `allow-popups-to-escape-sandbox`
must stay absent, and the test names the offending token rather than
printing a set diff.

**`@tauri-apps/plugin-store` is gone** from `package.json` — its
capability grants were removed as a host-file-write primitive and nothing
in `app/src` imports it. The lockfile was updated with
`--package-lock-only`, deliberately: `node_modules` is a symlink shared
with other worktrees and a real install would have pulled it out from
under them.

Nothing under `src-tauri/` is touched. 663 frontend tests pass (was 635),
`tsc --noEmit` clean, `npm run build` green, `cargo test` 446 unchanged.

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.

`wait_for_exec_exit` returning `None` used to mean "call it 0"; it now
fails the call, so a busy daemon that has not settled within ~1s would
turn into a spurious "the rename failed". The loop exits on the first
poll that reports finished, so a wider window costs nothing when things
are normal.

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.

shadow-testandClaude Opus 5 d6f065a2b6 Fix HIGH and MEDIUM frontend defects
Files pane
- F16: a drag-out released back inside the app no longer re-imports its own
  staged copy over the container original. An in-flight flag (cleared from the
  drag plugin's `onEvent` channel, with a watchdog) suppresses the drop and the
  "Drop files into …" hint, and an exact staged-path filter is the second line
  of defence — the `path|size|modified` cache could otherwise write a
  minutes-old snapshot over a file an agent had since rewritten.
- F17: a slow upload/rename no longer yanks the user back to the directory the
  operation started in. Every operation captures its target path and re-lists
  only if the user is still there; failures go to the toast host either way.
- The grid keeps keyboard focus. Roving tabindex (one tab stop, not one per
  row) plus focus restore after navigation, rename commit/cancel and Escape.
- Transient failures now surface in `ToastHost` (z-[60], persistent aria-live)
  instead of a `role="alert"` 300 rows down a scroller or behind a modal
  overlay. The inline error is kept only for the listing failure.
- `navigate` is sequenced by generation; "Save to host…" sets `busy`.
- Grid a11y: column headers, a text affordance for folder vs file, a live
  region that is mounted empty and announces completion, Label-in-Name fixed.
- FileViewerModal: the blob URL is released only once its replacement exists;
  the preview is a focusable, named, scrollable region.

Native drop routing
- New `lib/dropTarget.ts`: the hit test now refuses a drop while any
  `[aria-modal="true"]` dialog or `[data-blocks-drop]` overlay is up, and
  checks z-order where the environment can answer it. Shared by FilesTab and
  TerminalView; App's shutdown overlay opts in.

Disk
- A partially failed reclaim says so in words ("… — 2 of 5 failed"), not by hue
  alone.
- The scan/reclaim race is closed: every mutation retires an in-flight scan, so
  a scan can no longer repaint a pre-reclaim report plus a clickable plan of
  objects that are gone. Scan is disabled while working; the status is a live
  region; a failed destructive action keeps its dialog open and reports there.
- The "unknown" layer count gets a screen-reader fallback; `--text-disabled`
  no longer carries live information.

Terminal / OAuth
- After the toast is dismissed, a truncated heuristic guess can no longer fill
  the slot that an exact OSC 8 or relay URL occupied — the detector remembers
  every exact URL and drops any candidate that is a strict prefix of one.
- The prompt is reachable by keyboard: Ctrl+Shift+O jumps to the default
  action, Escape dismisses, focus returns to the terminal, and auto-dismiss
  holds off while focus is inside. It deliberately does not steal focus.
- UrlToast renders through `ui/Button` and `--shadow-overlay`.

Elsewhere
- AuthBridgeRow: a pushed `auth-bridge-changed` status always outranks an older
  awaited toggle result.
- The last two ad-hoc byte formatters route through `lib/formatBytes`.

Contract for the backend agent: `upload_file_to_container` refusing to
overwrite must satisfy `isFileExistsError` in `src/lib/uploadErrors.ts` (marker
`FILE_EXISTS`) and accept an `overwrite` argument; the frontend turns that into
an `ui/Modal` Replace/Skip prompt rather than a raw error string.

Tests: 536 -> 627 passing. `npm run build` and `npx tsc --noEmit` green.

Safety:

- `destroy`'s rollback-pin arm took a tag over IPC and interpolated it

  the project's live snapshot, deleted under a dialog saying "rollback
  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.

shadow-testandClaude Opus 5 dd2894cc60 Stop Docker disk growth, and fix the Claude Code settings that never worked
Two independent sets of fixes.

## Disk: stop the growth, no UI this round

The dangling-snapshot sweep was already correct and was never the leak. The
leak is that every `docker commit` **stacks** a layer and nothing compacts one:
a file deleted after it has been committed becomes a whiteout, not free bytes.
24 conditions trigger recreation+commit, so changing one settings field costs a
multi-gigabyte layer for the life of the project. One project was measured with
14 stacked commit layers, ~5.1 GB above its base.

* **Scrub the writable layer before every commit** (`docker/container.rs`,
  `SNAPSHOT_SCRUB_PATHS` / `scrub_writable_layer`). The one moment those bytes
  are still free to drop is before the commit that captures them. Measured on
  one container's 4.48 GB pending layer: 3.0 GB of agent scratchpad under
  `/tmp/claude-*`, the terminal drag-drop staging area (256 MiB per file, with
  no `rm` for it anywhere in the repo), a PNG per pasted image, and the apt
  lists/cache/logs that `browser_view/install.rs` and `triple-c-playwright-heal`
  leave behind with no `apt-get clean`. A hardcoded list, never a heuristic:
  `/workspace/{mount_name}` is a host bind mount and nothing here may reach one,
  and the three `/tmp` globs cannot select the read-only `.host-ca`/`.host-aws`
  mounts. Failure is a log line — a scrub must never block a snapshot.

* **Cap container logs** (`capped_log_config`). There was no `LogConfig`
  anywhere, so containers ran on the daemon's unbounded `json-file` default.
  Deliberately *not* wired into `container_needs_recreation`: participating
  would recreate every project once, and a recreation costs a commit, which is
  the thing being fixed. Picked up on the next natural recreation.

* **Make superseded base images sweepable** (`container/Dockerfile`). It carried
  no `LABEL` at all, so `orphan_sweep_filters`' `dangling` + `triple-c.managed`
  pair provably could not match one — ~11.9 GB observed stranded. Stamping
  `triple-c.managed=true` is the whole fix; the sweep needed no change.
  `create_container` writes the new `triple-c.base` key explicitly empty, or
  Docker's label inheritance plus `docker commit` would make every snapshot
  claim to be a base image. `force: false` stays, and now says why.

* **Sweep at startup** (`lib.rs`), not only after recreation: probes first
  (a probe pins an image the unforced sweep then refuses), pins second, sweep
  last. `sweep_orphaned_snapshots_logged` exists because all three callers threw
  the report away — `reclaimed_bytes`, `failed` and `unavailable` included.

* **Reap migration leftovers.** `rollback_migration` retagged and orphaned the
  migrated snapshot with no sweep. Stale `pre-migration-*` pins are now
  age-reaped by scanning the tag pattern rather than trusting the state file —
  `migration_store::load` reports an unparseable record as absent, which
  stranded a 4-12 GB pin nothing could name again; `load` now moves a corrupt
  record aside so `has_record` is trustworthy. A pin whose migration is still
  awaiting confirmation is never reaped at any age. The probe container's
  removal was a plain statement after an await, so a dropped future (an app quit
  mid-migration) leaked a container pinning a multi-gigabyte image; it is a
  `Drop` guard now, with `reap_probe_containers` for the case where the process
  itself dies.

* **Prune scheduler logs.** `remove` deleted a task's JSON but never its log
  directory, and the task runner appended uncapped `claude -p` output.

* **Fix the delete copy.** It said "the container, config volume, and stored
  credentials"; it removes *both* volumes and the snapshot image.

No prune UI, and no unfiltered `prune_images`/`prune_volumes` anywhere — the
daemon is shared with the user's unrelated work.

## Claude Code settings: two invented keys, one inverted default, one sticky bug

Verified against code.claude.com/docs/en/settings-reference.md and env-vars.md.

* `effort` -> **`effortLevel`**, the key Claude Code actually reads; the old one
  was written and silently ignored. `xhigh` added to the dropdown.
* `focusMode` -> **`viewMode: "focus"`**. `focusMode` was invented. The real key
  does exactly what the existing UI hint already described.
* **Session recap was inverted.** Claude Code's recap is on by default, so
  `CLAUDE_CODE_ENABLE_AWAY_SUMMARY=1`-when-enabled was a no-op and the control
  could never turn the recap *off*. The field is renamed to
  `session_recap_disabled` rather than reused: reusing the name with the
  opposite meaning would have read every stored `enable_session_recap: false` —
  which is every project that never touched the control — as "the user turned
  this off".
* **The stickiness, which is the important one.** Keys were emitted only when
  non-default, and the entrypoint *merges* into a settings.json on a persisted
  volume, so switching a setting off omitted its key, the merge preserved the
  stale on-value, and the setting stayed on until a destructive Reset. The fix
  already existed in the same file — the sandbox block is emitted
  unconditionally for exactly this reason — and is now applied to all five keys.
  A key whose neutral state is *unset* (`tui`, `effortLevel`, `viewMode`,
  `awaySummaryEnabled`) is emitted as JSON `null` and the entrypoint deletes it,
  because a stand-in value is not neutral: `tui: "default"` pins the classic
  renderer where unset lets Claude Code choose, and `viewMode: "default"`
  overrides the user's own sticky `/focus` choice.
* The same stickiness existed, unnoticed, in the **env vars**: `docker commit`
  bakes container env into the snapshot image, so a `=1` written once rode it
  forever. All four are now emitted on every create, extracted into
  `claude_code_env_vars` and unit tested. Two use an empty value for "off"
  rather than `0`, because they outrank a setting the user can change from
  inside their own container and Triple-C's default must not overrule a
  `/config` choice it never asked about.
* TUI mode is now a genuine three-way choice (automatic / classic / fullscreen),
  which the always-emitted key makes both necessary and possible.

`merge_claude_code_settings` is untouched by choice: a project-level OFF still
cannot override a globally-ON setting.

Tests: 364 frontend (+5), 308 Rust (+23), covering the scrub path list and
script, log rotation, pin reaping, and that toggling a setting off actually
clears a previously-set ON value.

shadow-testandClaude Opus 5 22d142c70d Shift+Enter newline, OAuth URL truncation, and the auth bridge toggle
Three fixes that all land on the same journey: sign in, paste a prompt,
and have the terminal behave the way every other Claude Code host does.

Shift+Enter inserts a newline
-----------------------------
xterm.js does not consult `shiftKey` for Enter (`Keyboard.ts`, case 13),
so Shift+Enter was byte-identical to Enter and submitted the prompt.
Both terminals now send `\x1b\r` (ESC+CR) instead, which Claude Code
parses as return+meta — the same bytes its own `/terminal-setup` writes
into the VS Code, Cursor, Alacritty and Zed keymaps, so this is in-band
rather than a guess. Not `\n`: Claude Code accepts it, but a shell would
run the line, so the two session types would diverge. Bound in Claude
sessions only for that reason.

`entrypoint.sh` sets `shiftEnterKeyBindingInstalled` in `~/.claude.json`
so the CLI stops printing its "run /terminal-setup" tip. Purely
cosmetic — the decoding is unconditional either way.

Alt+Enter has always done the same thing (xterm ESC-prefixes on altKey)
and was simply never documented. It is now, along with the rest.

OAuth login URL truncation
--------------------------
Two producers wrote one toast slot, last-writer-wins. The OSC 7777 relay
delivers the URL base64-encoded and therefore exact; ~300 ms later the
screen-scraper's debounce fired and overwrote it with a truncated guess
at the same link — a URL that parses, points at the right host, and
authorises nothing. The user is the one who has to notice.

Why the scraper truncated: `ANSI_RE` strips OSC sequences wholesale,
including the OSC 8 hyperlink whose parameter carries the complete URL.
Claude Code slices the *visible* text of that hyperlink to the terminal
width while every emission carries the whole URL in its parameter. The
backend already knew this (`commands/auth_token_commands.rs`); the
frontend did not.

- `urlDetector` now reads OSC 8 targets out of the raw buffer before
  stripping, filtered by a port of `usable_sign_in_link`, and tags every
  candidate with its provenance.
- The prompt slot gained `supersedes`: better provenance always wins,
  worse never does, and between equals only a candidate that *extends*
  what is showing may replace it. That last rule is `extendsUrl`,
  factored out of `pickSignInUrl` rather than copied — same rule, same
  reason, one implementation.
- `flatten` splits on a bare `\r` as well as on `\r?\n`, so a
  `\r`-repainted TUI frame no longer inflates a line past the width and
  suppresses a join that should have happened; and the width is now
  sampled at `feed()` rather than read at `scan()`, so a resize inside
  the 300 ms debounce cannot reassemble 80-column text against a
  120-column rule.

Also corrects the comment claiming `acquire_claude_token` enables the
auth bridge. It deliberately does not, and the module comment in
`auth_token_commands.rs` explains at length why not.

The auth bridge toggle
----------------------
`setAuthBridgeEnabled` and `getAuthBridgeStatus` had zero call sites:
the Rust was complete, the IPC wrapper shipped, and there was nowhere to
click — so the docs told users to "enable the Auth Bridge" for a switch
that did not exist. `AuthBridgeRow` is that switch, in Config → Runtime.
It deliberately does not go through the tab's stopped-only save: the
dedicated command exists so the bridge can be flipped while a login is
hanging in a running container, which is the only moment anyone reaches
for it.

It also subscribes to `auth-bridge-changed`, which the poller has been
emitting to nobody — so a host port the bridge could not take was a
completely silent failure, indistinguishable from a login that hung.

`tunnel.rs` promotes the best-effort `::1` bind failure from debug to a
warning recorded on the port. Half-bound is the failure mode that looks
like success: the status says bridged, and a client that resolves
`localhost` to `::1` without falling back is still refused.

Finally, for a recognised Anthropic sign-in URL the toast now leads with
"In container" and demotes the host "Open". The callback listener is
inside the container, so the container-side browser closes the loop with
no host round trip and no auth bridge; the host button stays as the
fallback. Ordinary URLs are unchanged.

Tests: 402 frontend (was 359), 285 Rust (unchanged).

shadow-testandClaude Opus 5 15e05e2197 Turn the Files tab into a real file manager
Rename, an in-app viewer for text and images, host-to-container drag and
drop, New folder, keyboard operation — plus the pre-existing bugs the new
surface would otherwise have been built on top of.

New Tauri commands (file_commands.rs, registered in lib.rs):

* rename_container_path — `mv -n -- <from> <parent>/<name>` through
  exec_oneshot_as, so the *exit code* is checked. exec_oneshot discards the
  status and interleaves stderr into stdout, which would have made a
  permission failure look like a success. `mv -n` on its own is not enough
  either: GNU coreutils makes its refusal to clobber silent and exits 0, so
  an explicit `test -e` on the destination is what turns a name clash into
  an error the user sees. `mv`'s own words are surfaced, since renames
  outside /workspace legitimately fail on permissions. The new name is
  validated in Rust (no `/`, no NUL, not "." / ".." / empty, ≤255 bytes) —
  it is user text going into argv, and a name with a separator would be a
  move rather than a rename.
* read_container_file — exact bytes via Docker's archive endpoint, returned
  as base64. Deliberately not exec_oneshot, which runs every chunk through
  String::from_utf8_lossy and merges stderr, so it would corrupt any
  non-UTF-8 file and could splice diagnostics into content. Base64 rather
  than Vec<u8> because Tauri serialises a byte vec as a JSON number array.
  Capped and truncation-reporting; the caller picks the cap (images get 5
  MiB against text's 1 MiB, being the kind that blows a text-sized budget)
  and Rust clamps it to 8 MiB regardless.
* create_container_directory — `mkdir` without -p, so a clash is an error
  rather than a silent success. Named for its siblings rather than the bare
  `create_directory` in the brief.

The tar-extraction half of download_container_file is now the shared
fetch_container_file() both commands use, and it abandons the transfer once
a capped read has what it needs.

Frontend:

* Single click selects, double click opens. Directory navigation moved onto
  double click too — a single click used to navigate, which made it
  impossible to select a directory in order to rename it. Rows are now
  focusable and the table is a real `grid`: Enter opens, F2 renames, arrows
  walk the rows. No outline suppression; the global :focus-visible ring is
  what shows focus.
* FileViewerModal (built on ui/Modal, the only correct dialog) renders text
  in a <pre> and images from a revocable blob: URL. tauri.conf.json's
  img-src had neither `data:` nor `blob:`, so an in-app image was blocked by
  CSP; `blob:` is added — revocable, and no megabytes of base64 in the DOM.
  The asset protocol stays disabled. Anything else gets a "Save to host"
  state instead of a broken preview, decided by extension and then by
  sniffing the bytes for NUL.
* Host drag-and-drop uses Tauri's native onDragDropEvent, mirroring
  TerminalView: HTML5 ondrop carries no paths and is blocked in the webview
  on Windows by dragDropEnabled, which the terminal needs. The listener is
  window-wide, so it routes by hit-testing the payload position (physical
  pixels, hence the devicePixelRatio divide) against the pane's rect — a
  hidden pane has a zero-size rect and never matches, which is what keeps
  this and the terminal's listener apart. enter/over/leave drive a drop
  highlight.
* Per-row Download is now "Save to host…"; directories no longer offer it.

Pre-existing bugs fixed:

* Uploaded files landed root:root with a 1970 mtime. tar::Header::new_gnu()
  zeroes uid/gid/mtime and Docker honours the header verbatim, so uploads
  were not writable by `claude`. All four single-file tar builds now go
  through build_single_file_tar() with the container user's ids, read from
  the container because entrypoint.sh remaps them to the host user on Unix
  and deliberately does not on Windows.
* Symlinked directories could not be opened: `find -printf '%y'` reports `l`.
  The listing now prints `%Y` as well, so is_directory dereferences and a
  new is_symlink carries what `%y` used to say. The row labels the link.
* upload_file_to_container had no size cap and did a synchronous fs::read on
  an async worker. Now 256 MiB (matching the terminal drop path) with the
  read and tar build in spawn_blocking, and the host mtime preserved.
* A directory passed to upload reached fs::read and produced an opaque "Is a
  directory". Rejected with an explanation instead — recursive upload is a
  larger feature than this panel needs.
* download_container_file wrote the *first tar entry*, so downloading a
  directory silently produced a garbage file. Non-regular entries are now an
  explicit error.

Tests: 46 new (33 frontend across FilesTab, useFileManager and filePreview;
12 Rust covering the find-output parser and the rename validator, neither of
which had any). 405 frontend / 297 Rust, both green.

No drag-out dependency was added — tauri-plugin-drag is not introduced and
OS drag-out is not attempted; that stays deferred, with "Save to host…" as
the way files leave the container.

shadow-testandClaude Opus 5 48d0c3249a Fix two bugs in last round's fixes, and stop --full hiding the Docker host
Round 3 found defects in code written an hour earlier. Both reproduced.

**The handshake poll accepted empty output as a completed handshake.**
`[ "$(… | awk '{print $2}')" != 0 ]` is *true* when `wg show` prints nothing —
which it does when the interface has no peer, and when the interface is gone
(that message goes to stderr). `until` suspends `set -e` and `pipefail`, so
nothing else caught it. The poll added last round to make "success without a
tunnel" impossible produced exactly that. Now requires a number greater than
zero, and waits 20s rather than 10 so a slow link is not rolled back needlessly.

**`down` still sat above the key registration.** Last round moved it below the
token and server-list fetches but not below `addKey`, which is the most
failure-prone of the three — one gateway, by CN, pinned certificate. So a
refused registration still tore down a working tunnel. It now runs after the
last fetch; the key is generated before but written after, since `down` deletes
it. SKILL.md said "after every network fetch has succeeded", which was false;
corrected.

**`up --full` made `host.docker.internal` unresolvable — and `status` said DNS
was fine.** That name is answered only by the resolver being replaced; it is not
in `/etc/hosts`. `gateway.rs` hands it to every container for the LiteLLM
gateway, and Ollama and custom endpoints default to it, so an agent running
`up --full` silently removed the project's model backend. The route was already
excluded; only the name was lost. Now resolved with the old resolver and pinned
into `/etc/hosts` before the swap, restored on teardown, and `status` probes it
— PIA answers public names happily, which is precisely why probing only
`api.anthropic.com` reported "ok". Documented as Trap 4.

**The rollback could abort halfway.** The trap's `{ … }` is not exempt from
`set -e`, and `down`'s `cat`/`tac`/`rm` had no `|| true` — so one failure left
the interface up with all traffic captured, after printing "rolling back".
`down` now runs under `set +e`, the trap tolerates its failure, and the
interface is deleted *first*, since that removes every route pointing at it.

**The account password had a real argv window.** curl does blank `-u`, but only
once running: sampling /proc/<pid>/cmdline caught the plaintext in 2 of 400
tries, between exec and the overwrite. Small, but it is the permanent password
and the token already had the fix. Moved onto the same stdin config — 0 of 400.
Review reported this as a 25-second exposure; that was a wrapper's argv, not
curl's.

entrypoint: the skill install stages into `$_dest.new` and swaps, so a failed
copy leaves the previous copy intact instead of a truncated SKILL.md and no
script, root-owned, on a persisted volume. Verified against a size-limited
filesystem.

shadow-testandClaude Opus 5 5b96ad4823 Stop a failed up from tearing down a working tunnel
The previous commit moved `down` to the top of `up` to fix a resolv.conf
idempotency bug, and in doing so put it *before* every network fetch that can
fail. Re-review caught it and I reproduced it: with a tunnel up, an `up` that
fails on bad credentials left `pia0` gone and traffic silently back on the real
address, while the error talked only about credentials. A privacy regression
introduced by a correctness fix.

`down` now runs after the token, server list and key registration have all
succeeded — nothing above that line touches the network stack — and still
clears the stale backup it was added for.

Everything after it is covered by a rollback. Note this is an EXIT trap with a
flag, not `trap ... ERR`: my first attempt used ERR and did not fire at all,
because ERR is not inherited by shell functions without `set -E`, so a failure
inside add_route missed it, and `die` exits explicitly, which is not an error.
Verified by forcing a route collision — the tunnel is torn down and DNS is
intact, where before the fix it was left half-configured with DNS dead.

Also from the review:

- **The private key lived on disk for the whole life of the tunnel.**
  `commit_container_snapshot` blanks env vars, never files, and nothing tears
  the tunnel down before a recreate or migrate — so the `down`-time cleanup
  never covered the path that put a key in a snapshot in the first place. It is
  now deleted the moment `wg set` has read it; the kernel keeps its own copy,
  verified by checking the interface still works afterwards.
- **`up` claimed success without a handshake.** An unreachable peer still
  routes — into a black hole — so `up --full` could exit 0 having pointed all
  traffic and resolv.conf at a peer that never answered, with `status` printing
  "mode: full tunnel". Now polls for a handshake and rolls back if none arrives.
- **`status` needed root and did not check.** `wg show` fails unprivileged and
  was swallowed, so an unprivileged run printed "no tunnel up" and then "mode:
  full tunnel" in the same breath. An agent reading the first line would re-run
  `up` — which, before the fix above, destroyed the tunnel it failed to see.
- **The killswitch bullet was false.** It said `iptables` is not in the image;
  it is, so a killswitch is buildable. It stays unbuilt because it would cut
  Claude Code's own API traffic — an honest reason, unlike the previous one.
- `install_feature_skill` rejects path-traversal names, not just blank ones —
  verified `../skills` would have deleted the whole skills directory including
  Mission Control's — and reports `mkdir`/`cp` failures instead of printing a
  success line regardless.
- The usage text ended by printing `set -euo pipefail`, off by one line.
- HOW-TO-USE claimed "the container says so on start". entrypoint prints to
  PID 1's stdout, which no terminal or UI surfaces — `docker logs` appears
  nowhere in the repo. Now points at the migration pre-flight, which does.

shadow-testandClaude Opus 5 dcb13d23ea Fix what review found in the skill: five real defects
Adversarial review of #29 found bugs I confirmed by reproducing each one.

**Every hand-written error message was unreachable.** `tok=$(curl ...)` is a
plain assignment, so `set -e` acts on the command substitution before the
following `|| die` can run. A wrong password produced exit 22 and no output at
all — the most likely way this gets used wrongly, and the least explained.
All four captures now go through a `run` helper that takes a *description*
rather than echoing the command, because one of them carries the account
password in `-u`.

**`up` was not idempotent, and the second run destroyed DNS.** The resolv.conf
backup was copied unconditionally, so `up --full` twice overwrote the good
backup with PIA's own resolvers; the later `down` then "restored" those and
left the container with no working DNS and no way back. `up` now runs `down`
first. Verified: two `up --full` runs, then `down`, and the backup still holds
the original 192.168.65.7.

**An empty gateway produced total connectivity loss, reported as healthy.**
`$gw` was never validated and `add_route` swallowed every failure to /dev/null.
The two half-routes need no gateway and would succeed, so the tunnel captured
everything while the exclusions keeping DNS and the Docker host reachable
silently did not exist — and `status` still printed "full tunnel". Routes are
now fatal on failure, and a via-less default (`$3` is the literal "eth0") is
rejected.

**The PIA session token was in the process arguments** — confirmed in `ps` and
/proc/*/cmdline, a ~24h bearer credential for the account readable by anything
in the container. It now goes to curl on stdin as a config. Verified: 60 polls
across a full `up`, zero sightings.

**The preflight diagnosed the wrong kernel module.** It checked /dev/net/tun
and blamed the tun module, but kernel WireGuard is a netlink interface and does
not use it — verified by creating one with NET_ADMIN and no tun device. The
check is dropped (the container could not have started without the device
anyway) and `ip link add` now reports the real dependency.

Also: a full tunnel with no DNS servers from PIA used to warn and carry on,
which is a tunnel leaking every lookup while reporting itself healthy — now
fatal. `down` validates the backup before restoring it, so a truncated one
cannot leave the container with no resolver at all. `wg.priv` is shredded on
teardown and created under umask 077, because /run rides `docker commit` into
the snapshot image. A mistyped `up --ful` is rejected instead of silently
giving a test route.

entrypoint: `install_feature_skill` gets `local`, a blank-name guard (the
disabled branch would otherwise `rm -rf` the whole skills directory under a
persisted volume), `-e`/`-L` so a leftover *file* at the destination is cleaned
up, and a chown of the parent so `claude` can still add skills of their own
when Mission Control is off. When the base image predates the skill it now says
so instead of returning silently — and `/opt/triple-c-skills` joins
FEATURE_PROBES so the migration pre-flight reports it. Docs corrected to match:
neither half reaches an existing project without a migration.

`vpn_env_var` extracted and tested, pinning the property the whole removal path
rests on — that the variable is emitted as 0 rather than omitted.

shadow-testandClaude Opus 5 7a8bbcbef7 Report which exit is which, instead of one ambiguous "public IP"
`status` probed https://1.1.1.1/cdn-cgi/trace and printed the answer as
"public IP". In test mode 1.1.1.1 is the *only* address routed into the tunnel,
so that line reported a PIA exit while every other packet left directly — a
test tunnel reading exactly like a full one.

Found on a live container: default route still via eth0, one 1.1.1.1/32 route
through pia0, and the old status line claiming a PIA public IP. This is a
plausible route to concluding the VPN is on when it is not, which is close to
the confusion this skill exists to prevent.

Status now names the mode and, in test mode, prints both exits with the real
address called out. 1.0.0.1 serves the same trace endpoint as 1.1.1.1 and is
never routed into the tunnel, so the direct exit can be probed without DNS.

Verified against all four states: no tunnel, test mode on a live tunnel that
was already up, full tunnel, and after teardown.
