The new informational Windows job surfaced 91 failures: four real bugs (fixed in
the previous two commits) and a long tail of POSIX assumptions in the tests
themselves. None of them assert behaviour that differs on Windows, so they are
fixed rather than skipped wherever the behaviour is the same:
* Path spelling: expectations built with `str(tmp_path)` are compared through an
identity helper (`normalize_root_identity`) or the platform's separator, since
the code hands out forward-slashed business paths while `str()` is native.
* Root labels: `_root_display_labels` prefixes the drive on Windows ("C: loras"),
so label assertions compare the final path component or derive the expected
label from the same helper.
* `~` expansion reads USERPROFILE (ntpath), not HOME; timer granularity rounds
0.1s down; a case-only rename counts as "already named" via `os.path.normcase`.
* Genuinely POSIX-only strategies are skipped with a reason instead of failing:
the headless clipboard fallback, dbus file-manager selection, xdg-open, and
the case-fold index test that simulates a case-sensitive filesystem.
`Config._dedupe_existing_paths()` drops roots whose directory does not exist
when the root list is built, so a drive that is switched off while LM starts was
not "an offline root" — it was not a root at all. The Refresh ▾ menu had no row
for it in either state, a full refresh reported nothing (its cached entries
survived only because they fall outside every configured prefix), and plugging
the drive back in changed nothing until the next restart.
* `Config` now records the configured (existence-unfiltered) paths per model
type — from ComfyUI's list in plugin mode, from the active library snapshot in
standalone mode, where the host mock filters non-existent paths itself — and
exposes them through `configured_roots_for()`.
* `ModelScanner.describe_model_roots()` appends configured-but-unavailable roots
with a live `reachable`, an `available` flag and their cached entry count, so
`/roots` (and therefore the menu) offers a row in both states: greyed while the
directory is missing, normal and clickable once it is back.
* `_reconcile_cache()` reports them as `skipped_roots` / `unavailable_paths` with
reason `root_unavailable` and counts their cached entries in `kept_unreachable`,
which is what makes the "N models kept" toast appear in the startup-offline
case. Report-only: they stay outside the scan scope, so nothing about pruning
changes. A root-scoped scan stays quiet about roots it was not asked about, and
a folder-scoped scan only mentions a missing root that holds cached entries of
that folder.
* `Config.admit_configured_roots()` re-runs the per-type prepare helpers against
the configured paths and APPENDS what is readable now (plus the
checkpoint/unet/other side maps), then refreshes the preview allowlist, so a
drive plugged in mid-session can be scanned without restarting. Append-only and
order-preserving by design: removing a root mid-session would let a later
settings save persist the loss, and re-sorting would move `*_roots[0]`, which
derives the recipes directory and the usage-stats file location. `_roots[0]`
never moves.
* `/roots` and `/scan` admit first, so `describe_model_roots()` stays a pure read
and a caller that never opens the menu (the browser extension) still gets a
drive that came back.
Verified on the sandbox with drive-Z switched off before startup: `/roots`
reports `drive-Z reachable=false available=false models=60`, a full refresh
returns `skipped_roots=[drive-Z root_unavailable]`,
`unavailable_paths=[{... kept: 60}]`, `kept_unreachable=60`, and all 432 models
stay cached. Renaming the drive back while the server runs admits it
(`available=true`) and `GET /scan?roots=<drive-Z>` walks it with no restart.
3714 passed, 7 skipped; frontend 1495 passed (149 files); vue widgets 96 passed.
