A user could select another local file with the same name as one that already
exists in completed storage. The upload would be allowed to start and only hit
an existing-file conflict late in the flow, which made the UI look like the
file was uploadable.
Reject duplicate sanitized names during upload creation so no staging record or
chunk transfer starts for a file that cannot be completed. Keep the completion
path non-replacing as a second guard by promoting through a no-overwrite file
creation path, with a hard-link fast path and copy fallback for custom temp
locations.
The browser now treats the server's duplicate-name conflict as a terminal row:
it disables the action, marks the item visually, and tells the user to rename
the file if they want to upload that copy.

The browser upload flow was built around one selected file and one global
upload state. That made the existing chunk pool useful for a single file, but
users could not start several selected files at the same time.
Refactor the browser state into per-file upload items. Each selected file now
has its own upload record, completed-chunk set, abort controller, retry state,
progress row, and saved IndexedDB resume record. The picker accepts multiple
files, `Start all` and `Resume all` use a bounded file-level pool, and each file
keeps the existing bounded chunk pool. This keeps parallel uploads useful
without letting one large selection create unbounded request fan-out.
Keep the server API unchanged. Each file still receives a separate server upload
id, and server-side progress remains authoritative before any missing chunks are
scheduled. Terminal conflicts still stop the affected file without overwriting
completed data.
Update the user-facing markup, styles, project docs, and test checklist for the
multi-file scheduler. Add a server regression test that interleaves two uploads
and verifies the completed files contain exactly their own bytes.

A newly selected file has no server upload record yet, so the UI calls the
progress renderer with zero completed chunks and zero total chunks. Treating
that zero-total state as complete made the progress bar jump to 100% before
any upload had started.
Render zero-total progress as empty instead. Existing resumable uploads still
show their server-authoritative completed chunk percentage, and completed
non-empty uploads still render as full because their completed count equals a
non-zero total.

The previous page showed a static "Server online" pill even though it did not
track backend liveness. It also left the selected file in an uploadable state
after completion, which made it too easy to start the same file again and then
land in a saved record that could only fail with "complete file already
exists".
Remove the misleading server-status UI and make saved uploads describe their
next action. Records with every chunk uploaded now show a Finish action, stale
server records are cleared, and a terminal "complete file already exists"
response clears the saved browser progress instead of inviting another resume.
A successful completion also clears the active file selection so the primary
actions settle back to idle.

Replace the placeholder browser script with the PLAN.md upload flow. The static
UI now creates upload records, slices the selected file into fixed-size chunks,
uploads missing chunks with a concurrency pool of three workers, retries failed
chunks with exponential backoff, pauses via AbortController, and completes the
upload once the server has accepted every chunk.
Persist pending upload records in IndexedDB and render them in the page so a
reload can resume from server-authoritative progress. When the File System
Access API is available, the app stores a file handle and asks for read
permission during resume; when it is unavailable or permission is denied, the
same pending record resumes after the user reselects the matching file. Browser
state is helpful but not trusted: every resume starts by querying the server for
completed chunks.
Add a JavaScript syntax check to the justfile, update the static-page test and
documentation, and extend TESTS.md with the manual resume scenarios that still
need real-browser repetition.

Introduce the first PLAN.md milestone: replace the hello-world binary with
an Axum server that binds to localhost by default, exposes a health endpoint,
and serves the static browser UI from the repository's static directory. The
router is available through the library crate so integration tests can exercise
server behavior without opening a network listener.
Add a justfile for routine validation and document the initial project shape,
configuration knobs, and reusable test checklist. The rustfmt config now uses
only stable options so the new formatting recipe runs without nightly warnings.
The upload API and resumable chunk behavior are intentionally left for later
milestones; the UI currently handles file selection only.
