Stop the pre-commit scrub running with its guards silently absent
Two fail-open gaps, both latent on the shipped image and both live on an ImageSource::Custom one. `--one-file-system` is the only bound on the scrub's `rm -rf`, and it was probed into `$rmopt` with `rm --one-file-system --help`. BusyBox answers that with `unrecognized option` and exits 1, so on any busybox- or toybox-derived image the variable was empty and the delete ran as root across mount boundaries — reported as a completed `Reclaimed(n)`. Measured in `busybox:latest` with a named volume one level below the match at /tmp/claude-x/inner: emptied, `###TRIPLE-C-SCRUBBED 102423`. It is a prerequisite now, probed by `rm --one-file-system -f -- ''` — the code path that matters, with the one operand no filesystem can name — and an image without it prints `###TRIPLE-C-SCRUB-UNAVAILABLE` and deletes nothing. That costs Alpine and busybox images their scrub, which is the cheaper half of the trade: declining costs disk, proceeding costs the mount. The second is that resetting `PATH` was never the whole of command lookup. `bash` builds functions out of `BASH_FUNC_<name>%%` environment variables, function lookup precedes `PATH` entirely, and `command -v` reports a function as found — so a planted `stat` passed the prerequisite probe and then answered the containment checks. Every in-shell answer is itself importable: `unset`, `command`, and — the point that settles it — `[`, `pwd` and `cd`, which are checks 0 to 2 rather than merely the tools. So the script is no longer run by the shell that read the environment. The exec's argv is a bootstrap using only reserved words, parameter expansions and command words containing a `/` (which `bash` refuses to import a function for), and it hands the script as `$1` to a second `/bin/sh` started by `env -i`. Measured on `/bin/sh -> bash` with `BASH_FUNC_stat%%` set on the container and a volume mounted at the match: the old invocation emptied it and printed 306565, the bootstrap left it intact and printed 65536. `/usr/bin/env` then `/bin/env`, because H3's lesson about hardcoded coreutils locations applies to `env` too. The comment claiming the `PATH` reset "defeats it just as completely as spelling /usr/bin/stat out" is corrected, as is the one claiming a sudo-written /usr/bin/stat does not survive a container restart — it lands in the writable layer, which is exactly what the commit this runs in front of captures. Also here: a stored project path row with an empty host_path or mount_name no longer becomes a mount. The first sends `field Source must not be empty` back for the whole create, so the project cannot start at all until the row is gone, and no amount of save-time validation reaches a record already on disk; the second mounts over /workspace itself and the daemon then creates the other rows' mount points inside the user's real folder. And in migration_commands, the deferred-reconcile claim is RAII rather than a trailing statement — a panic inside `reconcile_migration_now` stranded it for the rest of the process — and `await_release` looks before it sleeps, so a project released a moment later no longer costs a full twenty seconds.

Make the scrub work off /usr/bin, and stop a log level deciding whether it runs
H3 — the pre-commit scrub was a silent no-op on any base image whose coreutils
are not under /usr/bin. Hardening against a PATH-planted `stat` shim by naming
every tool absolutely bought nothing the `PATH` reset on the first line had not
already bought — the shim lives in the persisted home volume, and uid 1000
cannot write /usr/bin or /bin — and it cost the whole feature on Alpine, which
Settings -> Docker -> Custom accepts. Measured on one seeded tree in a real
container: the absolute-path script printed `###TRIPLE-C-SCRUBBED 0` and left
every planted file in place; the PATH-resolved one reclaims 77824 bytes. The
default image is unchanged at 521038.
It was silent three times over, and all three are fixed:
* The script now probes for all six things it needs (`command -v` for the five
tools, plus the root device id reading back as a number) and, if any is
missing, prints `###TRIPLE-C-SCRUB-UNAVAILABLE <what>` and no total at all.
* `scrub_writable_layer` reads that marker first and returns a new
`ScrubOutcome::Unavailable`, warning with what the image is missing; a
genuine `Reclaimed(0)` now leaves a debug line rather than nothing.
* `commit_log_suffix` renders `Reclaimed(0)` as "ran and found nothing to drop"
rather than "0.00 MB dropped", which is what a scrub that could not run used
to look like.
Verified in real containers: the mount-at-the-match defence still holds with a
home-volume `stat` shim first on PATH (the volume survives; deleting the PATH
reset from the same script empties it, so the harness can tell the difference).
H2 — the pre-migration scrub had been folded into `log::info!`'s argument list
to satisfy `#[must_use]`. `log::info!` expands to `if Info <= max_level() { … }`,
so the awaited scrub lived inside the level check, and `logging::init`
tolerates `dispatch.apply()` failing — which returns before `set_max_level` and
leaves the process at `Off`. In that state the scrub never ran and the layer
was committed into the longest-lived snapshot the app takes. The outcome is
bound first now, `logging::init` restores the level on failure and says so on
stderr, and a test scans all four files for an `.await` inside any `log::*!`
argument list.
Also:
* `reconcile_migration` deferred a held project instead of dropping it. Its
only caller fires once per "Docker became available", so a project held at
that instant was never revisited for the session — phase un-normalised, no
resume or rollback offered, pin left `Claimed`. It now waits for the holder
to let go (20s x 90, one waiter per project) and reconciles then.
* The scrub's byte total counts what a partly failed `rm` removed, by
re-measuring rather than dropping the whole subtree on a non-zero exit —
which was exactly the `--one-file-system` case.
* The scrub exec blanks `LD_PRELOAD`, `LD_AUDIT` and `LD_LIBRARY_PATH`.
`LD_PRELOAD` is in none of the reserved env families, so a project's custom
env var reached a root exec and injected code into every tool the scrub runs,
`PATH` reset or not. Verified against Engine 29.7 that `docker exec -e` wins.
* The device test is described honestly: it is a mount test under `overlay2`
and not under `vfs`, where checks 1 and 2 are what still hold.

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.

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.

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.

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.

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.

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.

A project can be out of date and say nothing about it, in two ways that
compound: the lineage lookup treats "unknown" as an answer, and the
fallback that exists for unknown lineage disappears when its probe fails.
`create_container` always writes triple-c.base-image-id, even when the
value is unknown — deliberately, so an inherited image label cannot ride
a snapshot forever. That makes Some("") the ordinary reading from a
container whose lineage was never established. The lookup filtered for
emptiness only on the final result, so that empty string satisfied the
container branch and skipped the snapshot entirely: a snapshot that had
recorded a real lineage was never consulted, and the project reported
"unknown" with the answer one lookup away. Each source is now filtered
before it can answer, in pick_recorded_lineage, which is a plain function
so the case has a test that fails against the old logic.
A genuinely pre-label project stays unknown, and should: its ancestor is
not knowable, and inventing one would make it look permanently current.
The probe is the intended signal for those — but if the probe failed,
get_container_staleness returned early with nothing populated, the banner
found no gaps and rendered null, and the probe_error it already knew how
to display sat behind a gate that returned before reaching it. Silence
there is indistinguishable from "up to date", and it is likeliest for the
oldest and largest projects, whose manifests are the ones apt to exceed
the inspection limit — one real project measured 6.93 MB against an 8 MB
cap. An unknown-lineage container whose probe failed now says the check
could not be completed, with the reason, under the tone that means
unresolved rather than the one that means something is wrong.

Every recreation commits the container to triple-c-snapshot-{id}:latest
and moves that tag; the image it pointed at keeps its layers and loses
its name. Nothing deleted those, so they accumulate — measured on one
real host, 7 orphans holding 7.4 GB, three of them from a single day's
work.
`sweep_orphaned_snapshots` removes them, under two conditions that are
the whole safety argument. Untagged: every image the app depends on
carries a tag, so a project's live `:latest` and a migration's
`pre-migration-*` rollback pin cannot match the filter at all. And
labelled `triple-c.managed=true`, which `docker commit` copies from the
container onto the image — the user's own dangling images are not ours
to delete. Removal is unforced on top of that, so Docker refuses while
any container is still built from the image, including the stopped
containers of projects that are not running; those are counted and left
for the next sweep.
It runs after a recreation, which is when the orphan it just made
becomes removable, and after a migration is accepted, which is the
moment dropping the pin turns the pre-migration snapshot into an orphan.
Both detached: this is housekeeping, and a full disk beats a project
that will not start. Each sweep clears every orphan it finds, so
recreations that predate it are cleaned up too.
The label string is now a constant rather than four literals, and a test
pins both filter conditions in place.

Fix review findings: secrets in snapshots, URL spoofing, migration data loss
Adversarial review of the branch produced findings across four areas. This addresses them, plus the Windows CI environment. Secrets. commit_container_snapshot baked the container's full env into the per-project snapshot image, so the shared OAuth token — and the AWS keys, git token and gateway master key — outlived revocation and were readable via docker inspect. Verified against Engine 29.6 that a commit body's config merges over the container's: keys cannot be dropped but can be overwritten, so all of them now commit as KEY=. clear_claude_token additionally rewrites images from earlier builds and reports honestly when a tag could not be rewritten. The recommendation to move the token out of env entirely was not taken, with reasoning: apiKeyHelper is a different auth method that outranks CLAUDE_CODE_OAUTH_TOKEN rather than a transport for it, and no file-based delivery exists. The durable exposure — the image — is what is closed here. Separately noted, not fixed: entrypoint.sh captures the token into the scheduler's .env inside the persisted volume. URL spoofing. Three call sites reached openUrl with container-controlled strings, one of which the review missed (the WebLinksAddon handler). The sign-in URL was scraped from container output with a longest-match tie-break and no userinfo check, so claude.ai@evil.tld rendered as "claude.ai…" in a truncating element. There is now one sanitizer in front of every sink — scheme allowlist, no userinfo, C0/C1 and quote rejection, host allowlist for the sign-in case, first-match — and the origin renders un-truncated. The toast is keyed so a changed URL remounts, closing a bait-and-switch where the user read one URL and clicked another. Migration. The rollback pin was best-effort: a tag failure was logged and the migration continued past remove_container, after which the final commit overwrote the only copy of the old system layer. It now aborts before anything destructive and reads the tag back. /var was destroyed while the ordinary recreate path preserves it — making the "safe" alternative to Reset more destructive than Reset's alternative; data-bearing subtrees are now detected and disclosed in the pre-flight rather than copied, since tarring a live database onto a different base's packages is a corruption risk. resume_migration now verifies the migration-state label instead of reporting success for a container that never swapped. dismiss actually resolves the record rather than leaving the feature permanently refusing to migrate. Start and Reset are guarded while a migration is live. Lifecycle. The gateway no longer publishes on 0.0.0.0 — bind address and advertised URL are derived together so they cannot drift. Disabling it now stops it. App exit runs teardown concurrently under a budget with a visible shutting-down state instead of blocking for minutes. Auto-starts retry when Docker is not up yet, and the polling-recovery path now reconciles, so interrupted migrations are still recovered. Auth-bridge forwards are capped, closing a container-driven fd exhaustion. Windows CI. build-windows failed on this branch with "linker link.exe not found". The runner had no MSVC build tools and the workflow assumed a hand-provisioned machine, so a bare runner registers, accepts jobs and fails at link time after downloading the whole crate graph. The job now installs the VC++ workload when vswhere cannot find it, matching how it already conditionally installs Rust and Node. 192 Rust tests, 274 frontend tests, both builds clean, zero warnings.

Migrate a project onto a new base image without losing its volumes
Projects were pinned to the image they were first created from. Both create paths preferred triple-c-snapshot-<id>:latest whenever it existed, and container_needs_recreation compared the container's live image against the triple-c.image label — which create_container wrote from the same image it created from. A tautology that could never fire. The only escape was Reset, which calls remove_project_volumes and destroys the login, skills and transcripts. Measured consequences on this host: real projects are missing socat (so the auth bridge cannot tunnel) and bubblewrap (so sandbox mode does not work), plus Mission Control and triple-c-sso-refresh, and sit 61 packages behind the base including ca-certificates, openssl and curl. Detection. create_container now writes triple-c.base-image-id (the image ID, not RepoDigests, which local-built and custom images do not have) and triple-c.create-image. container_needs_recreation takes the expected create-image and compares against the latter, so the check means something. base-image-id is deliberately NOT compared: a base bump would otherwise silently recreate from the snapshot, consuming the "you should migrate" signal without migrating. Staleness is surfaced, never acted on automatically. Migration keeps the volumes. /home/claude and ~/.claude are volumes and the image's copy is seed-only — permanently masked after first mount — so the login, ~/.claude.json, skills, transcripts, scheduler tasks, SSH keys, cargo, uv, ruff and Claude Code itself re-attach untouched. Only root-level state is rebuilt: apt packages are replayed against the new base rather than copied, so no stale libc is dragged forward, and /usr/local, /opt and the non-bind-mounted parts of /workspace are copied verbatim with tar --skip-old-files so they can never clobber a newer base binary. docker diff is not used: on a snapshot-derived container it reports only changes since the last commit. Raw image-vs-image diffing is filtered through dpkg ownership because it otherwise lies — 8,677 raw path differences on a real project reduced to 2 genuinely user-authored files, both loose /workspace-root files. Crash safety. snapshot:latest keeps pointing at the old image until the final commit, so any crash before it self-heals on next start. Later crashes are caught by reconcile_project_statuses. The rollback pin is a docker tag: 0.057s and 0 bytes. Rollback restores the system layer only — volumes are never touched — and the UI says so rather than implying a time machine. Fixes an infinite recreation loop shipped with the MCP removal. docker commit propagates labels to the image, so a container created from a snapshot inherited its non-empty triple-c.mcp-fingerprint and the one-shot shim recreated it again on every start, forever. Lineage labels are now always written explicitly. Documents the second, separate bug this uncovered: Dockerfile changes under /home/claude never reach an existing project, migration or not, because the volume masks them. Anything that must stay upgradable belongs in /usr/local/bin or /opt, or must be seeded by entrypoint.sh. 145 Rust tests, 227 frontend tests, both builds clean.
