Correcting a claim I merged in #85 an hour earlier, now that a real tablet exists to check it against.

What was wrong

On the Android tablet you do not choose the location: Obsidian creates the vault in its own storage and LiveSync populates it.

The tablet registers /storage/emulated/0/obsidian-work in LiveSync's own device registry (_local/obsydian_livesync_milestone on the server) — Android shared storage, not app-internal. So the location was chosen, and the doc said it couldn't be.

Same class of error as the ~/Notes correction in that same PR: a plan written down as though it were fact. The note recording that stays in rather than being quietly dropped.

Why it's worth more than a one-word fix

The two options have genuinely different risk profiles for a notes vault:

Shared storage App-internal
Survives uninstalling Obsidian Yes No
Reachable over USB / by other apps Yes No
Exposed to other apps on the device Yes No

Shared storage is the better fit here for the same reason the whole arrangement exists — the notes shouldn't be trapped inside one application. The cost is visibility to anything else on the device with storage permission, which is acceptable on a personal tablet and largely moot given the plaintext lives on the Macs regardless.

Also states the thing that does not follow: the tablet's vault still must not sit in a folder another sync app manages. Two sync systems on one vault loses notes on Android exactly as on macOS.

Verification

The cited path was re-read from the live milestone document while writing this, not recalled — both device entries confirmed, and the shared-storage claim checked programmatically rather than by eye.

Docs only.

…ared storage

The section merged in #85 claimed "On the Android tablet you do not choose the
location: Obsidian creates the vault in its own storage". Wrong, and now
checkable against a real device: the tablet registers
/storage/emulated/0/obsidian-work in LiveSync's own device registry
(_local/obsydian_livesync_milestone), which is Android SHARED storage, not
app-internal.

Same class of error as the ~/Notes correction in that same PR — a plan
written down as though it were fact — which is why the note about it stays in
rather than being quietly dropped.

Records the distinction as deliberate, because the two options differ in ways
that matter for a notes vault: shared storage survives uninstalling Obsidian
and is reachable over USB and by other apps, where app-internal storage is
neither. Shared is the better fit for the same reason the whole arrangement
exists — the notes should not be trapped inside one application — at the cost
of being visible to anything else on the device with storage permission,
which is acceptable on a personal tablet and moot given the plaintext lives
on the Macs anyway.

Also states the one thing that does not follow: the tablet's vault must still
not sit in a folder another sync app manages. Two sync systems on one vault
loses notes on Android exactly as on macOS.
