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 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 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.

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 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.
