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).

Project Home (DESIGN-REVIEW §B2): the project is promoted from a 280px
sidebar card to a first-class main-area view. ProjectCard.tsx (1,257
lines) is replaced by a select-only ProjectRow plus tabs for Overview,
Sessions, Automation, Config and Files. The PortMappings, FileManager
and ContainerProgress modals are absorbed rather than reimplemented.
Config gains a Saved/Saving/Failed indicator — save-on-blur failures
previously reached only console.error.
Tier-1 polish (DESIGN-REVIEW §A): new elevation, muted-accent, disabled
and focus-ring tokens; a global :focus-visible ring with every
focus:outline-none removed; filled buttons moved to --accent-emphasis
and white-on-success toggles retired, fixing three WCAG AA failures
(2.1:1, 2.5:1, 2.4:1); a shared Modal primitive with role="dialog",
focus trap and restore, adopted by all remaining modals; status
indicators that carry a glyph and word rather than colour alone.
Ctrl+Shift+W closes a tab, deliberately not Ctrl+W — that is readline's
kill-word, used constantly in the terminal this app is built around.
Auth Bridge: a general loopback-callback bridge so browser logins run
inside a container (aws sso login, Concourse fly login, claude login)
can complete against the host browser. Listeners are discovered from
/proc/net/tcp{,6} — ss/netstat/lsof are absent from the image — bound on
host 127.0.0.1 only, and tunnelled in over the Docker API via socat,
which keeps working on Docker Desktop where container IPs are not
routable. Falls back to [::1] because Node resolves localhost to IPv6
first, so claude login often binds ::1 alone. Opt-in per project.
This extracts create_attached_exec() and moves the existing terminal
session path onto it, so there is one attached-exec implementation
rather than two.
Shared auth token: `claude setup-token` is run in a container, the token
is stored in the OS keychain and injected as CLAUDE_CODE_OAUTH_TOKEN
into Anthropic-backend projects. Contrary to the initial design note,
setup-token uses an Anthropic-hosted redirect and blocks on a stdin
paste prompt rather than a loopback callback, so a stdin command is
required for the flow to complete.
The token is never logged, never returned to the frontend, and is
redacted from the streamed output with a stateful matcher that withholds
any tail that could still grow into a secret. Change detection uses a
random rotation id rather than a hash, since a hash in a docker-inspect
readable label would be an offline verification oracle.
Frontend 33 -> 51 tests; Rust 34 tests. Both builds clean.

Multiple-open accordion with per-section state persisted to
localStorage. Sections: General, Backends, Container, Git/SSH,
Tools, Updates. General is open by default; the rest are collapsed.

Rewrite Tooltip to use React portal (createPortal to document.body) so
tooltips render above all UI elements regardless of ancestor overflow:hidden.
Also increased max-width from 220px to 280px for longer descriptions.
Expanded Backend tooltip to explain each option (Anthropic, Bedrock,
Ollama, LiteLLM) with practical context for new users.

- Add circled ? help button in TopBar that opens a dialog with HOW-TO-USE.md content
- Create reusable Tooltip component with viewport-aware positioning
- Add 32 tooltip indicators across project config and settings panels
- Covers backend selection, Bedrock/Ollama/LiteLLM fields, Docker, AWS, MCP, and more
