Subject: [PATCH 2/3] tests/studio/install: parallel UNSLOTH_STUDIO_HOME smoke
 test (#5306)

* tests/studio/install: parallel UNSLOTH_STUDIO_HOME smoke test

Adds tests/studio/install/smoke_test_parallel_studio_home.py to lock in
the install-time and runtime isolation guarantees added by #5190.

The runner spawns N concurrent install.sh --local --no-torch jobs, each
with its own UNSLOTH_STUDIO_HOME and a redirected HOME, then launches N
backends on dynamically allocated ports and cross-checks every install
against its running process. Asserts:

  install-time
    - all N installs exit 0
    - per-install bin / share / llama.cpp / unsloth_studio venv tree
    - shim symlink resolves into its own venv, no cross-resolution
    - share/studio_install_id is unique across the N installs
    - share/studio.conf exports UNSLOTH_EXE / UNSLOTH_STUDIO_HOME /
      UNSLOTH_LLAMA_CPP_PATH all pointing inside the install
    - share/launch-studio.sh has @@DATA_DIR@@ substituted to its own
      share/ at install time
    - the redirected HOME stays clean: no rc-file append, no
      .desktop file, no Studio.app stub, no shared marker

  runtime
    - /api/health returns 200 with status healthy and chat_only true
    - /api/health.studio_root_id matches share/studio_install_id
      (runtime resolver agrees with install-time write)
    - studio_root_id values are pairwise distinct
    - GET / and GET /api/chat return 200 on each backend
    - /proc/PID/exe is the install's own venv python

Standalone smoke runner, not pytest collected. Default --n 4 finishes
in about 60 seconds on a warm uv cache; artifacts are removed on PASS
unless --keep is passed and kept on FAIL or ERROR for inspection.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* tests/studio/install: portability + log fd cleanup in parallel smoke

Two cleanups on the parallel UNSLOTH_STUDIO_HOME smoke runner:

- Skip the /proc/PID/exe runtime cross-resolution check on platforms
  without /proc (macOS, BSD, Windows). install.sh supports macOS, so
  the smoke should not hard-error there. The install-time symlink,
  studio.conf and launch-studio.sh assertions already pin the venv
  python target statically; the proc check stays as a Linux-only
  redundant cross-resolution catch and now returns None cleanly on
  other platforms instead of raising.

- Wrap the per-backend log file in a with-statement so its parent fd
  is released deterministically at function return. The child still
  holds its own dup'd fd via Popen, so logging continues unchanged.
  The prior code relied on local-scope GC and was fine in CPython,
  but the with form makes the intent explicit.

Smoke still passes locally: 4 parallel installs in 42s, 4 backends
healthy in 5s, all install + runtime invariants hold.

* tests/studio/install: pin UNSLOTH_STUDIO_HOME on backend launch

The launch step copied os.environ unchanged except for HOME. If the
parent shell already exports UNSLOTH_STUDIO_HOME or STUDIO_HOME (for
example, when the developer is sourcing studio.conf from an existing
install), every backend inherits it and the Studio resolver prioritises
those env vars over the per-label sys.prefix inference. The runtime
invariant block then reports the caller's install_id on every port
instead of the per-label one, and the test fails spuriously rather
than testing the right roots.

Pin UNSLOTH_STUDIO_HOME to the per-label studio_home and pop the
STUDIO_HOME alias for each launch, mirroring what _run_one_install
already does for the install step.

Verified by running the smoke with UNSLOTH_STUDIO_HOME=/nonexistent
and STUDIO_HOME=/also-bogus exported in the parent env: PASS, all four
backends report their own install_id rather than the parent value.

+"""Smoke test: N parallel install.sh runs with distinct UNSLOTH_STUDIO_HOME
+values must produce N fully isolated installs whose backends can run
+side by side without clashing.
+
+Covers the env-override path added in #5190:
+
+    install-time
+        * N concurrent ``install.sh --local --no-torch`` runs against
+          this checkout, each pinned to its own UNSLOTH_STUDIO_HOME and
+          a redirected HOME, all exit 0.
+        * Each STUDIO_HOME contains its own bin/, share/, llama.cpp/
+          and unsloth_studio/ venv, with no cross-install absolute
+          paths.
+        * share/studio_install_id is unique across the N installs.
+        * share/studio.conf exports UNSLOTH_EXE, UNSLOTH_STUDIO_HOME
+          and UNSLOTH_LLAMA_CPP_PATH, all pointing inside this install.
+        * share/launch-studio.sh has @@DATA_DIR@@ substituted to its
+          own share/ at install time.
+        * bin/unsloth is a symlink that resolves into its own venv.
+        * The redirected HOME is left clean: no shell-rc append, no
+          .desktop file, no Studio.app stub, no shared marker.
+
+    runtime
+        * N concurrent ``bin/unsloth studio`` launches each bind their
+          own dynamically allocated free port and stay healthy.
+        * /api/health is 200, status is healthy, chat_only is true
+          under --no-torch.
+        * The studio_root_id reported by /api/health on each backend
+          equals that install's share/studio_install_id, so the
+          runtime resolver agrees with the install-time write.
+        * studio_root_id values are pairwise distinct.
+        * GET / and GET /api/chat are 200 on every backend.
+        * The Python interpreter behind each PID is the install's own
+          venv python (the bin/unsloth shim does not cross-resolve).
+
+This is an integration smoke runner, not a pytest unit test. It does
+real installs (~1 minute end to end on a warm uv cache) and is meant
+to be invoked explicitly:
+
+    python tests/studio/install/smoke_test_parallel_studio_home.py
+    python tests/studio/install/smoke_test_parallel_studio_home.py --n 6 --keep
+
+Exits 0 on PASS, 1 on FAIL, 2 on infrastructure error. Artifacts land
+under a temporary directory and are removed on PASS unless --keep is
+set; on FAIL or ERROR they are kept regardless so logs can be
+inspected.

Subject: [PATCH 3/3] Studio: Dark theme refactor, right sidebar redesign, and
 chat UI polish (#5150)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Dark theme refactor, right sidebar redesign, and chat UI polish

- Dark theme refactor
- Redesign right sidebar
- Further left sidebar adjustments
- Wider chat and content area; layout tweaks for chat content
- Rounded corners across elements for consistency
- Show chat message menu icons on menu-area hover, not only on message hover
- Assistant message menu icons now always visible; user messages keep on-hover
- Redesigned copy icon used consistently across chat blocks and messages
- Redesigned trash icon, applied consistently
- Unified icon sizing and style with the sidebar
- Adjusted icon colors across chat
- Fix on-hover background design for chat icons
- Fix tooltip from 'more' button staying visible after clicking elsewhere
- Adjust position and design of generation speed info text below messages
- Adjust design of token speed info popup
- Adjust sidebar scrollbar to cover recent chats only

* Recents sidebar rename, UI/theme refactor, layout and chat polish

UI & Theme:
- Dark theme refactor
- Consistent rounded corners across elements
- CSS polish and cleanup
- Remove unused logo image assets

Recents sidebar:
- Add 'more' button for options menu
- Support renaming conversations and training runs
- Confirmation dialog before deleting chats
- Add optional display_name column to training_runs (idempotent ALTER TABLE) so renaming doesn't lose model_name/dataset_name from the run config
- New PATCH /api/train/runs/{run_id} endpoint accepts { display_name: string | null }; empty/whitespace clears the override
- Sidebar shows display_name ?? model_name and exposes Rename in the row's More menu, mirroring the chat rename flow
- Cache last list response in localStorage and hydrate from it on mount, so recents paint instantly on F5 / route revisit; cached items are shape-validated and dropped if malformed
- Optimistic updates on rename and delete (apply locally + cache before background refresh)
- Visible toast on rename/delete failure instead of swallowed errors

Layout:
- Redesigned right sidebar
- Further left sidebar adjustments
- Updated chat content layout; chat and content area slightly widened
- Sidebar scrollbar covers recent chats only

Icons:
- Redesigned copy icon, unified across chat blocks and messages
- Redesigned trash icon to match
- Consistent icon sizing and style across chat and sidebar
- Adjusted icon colors across chat
- Fix icon on-hover background design

Chat messages:
- Menu icons now appear on hover over the menu area, not just the message
- Assistant message menu icons always visible; user messages keep on-hover (next/previous response stays visible for edited prompts)
- Repositioned and restyled generation speed info text below messages
- Restyled token generation speed popup

Tooltips:
- Removed tooltip on hover for previous/next assistant response icons
- Unified tooltip design across sidebars and chat
- Removed tooltip animations (also fixes related lag)

Model & Chat Template config:
- Merged Chat Template config into Model Configuration section
- Added revert-to-original for chat template
- Fix Chat Template config disappearing on page refresh until model reload

Performance & scroll:
- Removed chatbox movement animations across pages/navigation (fixes related UI lag)
- Fix scroll flicker at end of streaming when a code block is the final element
- Additional chat scroll improvements

Bug fixes:
- Fix 'more' button tooltip remaining visible after clicking elsewhere

* Remove sidebar localStorage cache and optimistic updates

Drops the localStorage hydration and optimistic rename/delete logic from the recents sidebar; reverts to fetching fresh on mount.

* Fix missing cn import in shared-composer (regression from merge)

* chore(sidebar): import sidebar deps from feature indexes

Re-export deleteChatItem / renameChatItem / useChatSidebarItems / SidebarItem / useChatSearchStore / ChatSearchDialog from @/features/chat, and removeTrainingUnloadGuard from @/features/training. Switch app-sidebar.tsx to consume them via the public feature indexes instead of deep paths, clearing the no-restricted-imports eslint errors. No behavior or UX change.

* fix(studio/frontend): reload training Recents sidebar after F5 refresh

The Recents sidebar showed empty after a hard refresh. The hook's inFlightRef dedup guard collided with React StrictMode's double-mount in dev: the second mount's fetch returned silently with no error, no retry, and no toast — leaving the sidebar empty until navigation.

Replace skip-if-busy dedup with abort-previous via a hook-level AbortController. This also fixes a latent race where a slow poll could resurrect a just-deleted row by clobbering the optimistic update.

Changes (all in use-training-history-sidebar.ts):
- fetchRuns aborts any in-flight request before starting a new one; post-await signal.aborted check drops stale responses.
- Optimistic helpers (applyRunUpdate, removeRun) abort in-flight fetches so they don't depend on caller discipline to invalidate stale data.
- Initial load gets bounded retry-with-backoff (500ms / 1.5s / 3.5s) and surfaces a sonner toast with a Retry action on final failure.
- Failure toast auto-dismisses on any successful load (initial retry, Retry click, or polling recovery).
- Polling pauses while the tab is hidden and catches up on visible, avoiding wasted requests during long training runs.
- Both effects own their teardown explicitly (abort + clear timer).

* Apply unified tooltip design and behavior across remaining pages for consistency

* UI polish: spacing, tooltip on source icons, letter spacing, smaller icons, consistent edit icon

- Adjust tiny spacing between elements around the UI for subtle polish
- Redesign tooltip on source icons for web search / tool use, consistent with the new design
- Adjust chat text letter spacing
- Smaller icon sizes
- Replace 'edit message' icon in chat with the new Rename icon used in Recents for consistency

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Adjust CSS for right sidebar

* Fix scrollbar UI compatibility across browsers

* fix: preserve chat preset settings on model load

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix(studio): remove duplicate chat template status field

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* chore: remove creative preset assumption

* fix(studio): align speculative decoding default

* fix(studio/chat): snap numeric param inputs to step grid

- Type a value in any param input (Temperature, Top K, Max Tokens, etc.)
  now clamps to [min, max] and snaps to the slider's step grid, killing
  off-grid values like 1.051234 and FP residue from slider drags.
- Branch picker chevrons share the action bar's 32px height + 10px radius
  via a new .aui-branch-chevron-btn utility; hover area aligns visually
  while staying narrower than the sibling icon buttons.

* fix(studio/chat): keep training-run polls converging and drop dead preset code

- Keep training-run polls converging when responses outrun the 5s interval
  (don't unconditionally abort prior in-flight; skip if one is still pending,
  mutation race still guarded).
- Drop dead Creative/Precise preset code paths (remove 'builtin-fixed' source
  variant + unreachable branches).

* fix(studio): training-run cards show custom name + model + dataset

- Training-run cards now display custom display_name + model + dataset,
  with cross-view sync on rename/delete.
- Enhance clarity of borders and colors in dark theme on export etc.

* fix(studio): match active state green to unsloth brand color

* fix(studio): preserve can_resume on training rename

* fix(studio): keep GGUF chat template override distinct

* fix(studio): treat audio input models as multimodal

* fix(studio): cancel numeric draft on Escape

* fix(studio): use default speculative mode on toggle

* fix(studio): detect GGUF audio VLM input models

* fix(studio): address final PR review findings

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix(studio): refresh sidebar/history when a new training run starts so it appears without a manual reload

* fix: API and svg

* fix(studio/sidebar): align run rename dirty check with displayed baseline

* fix(studio/sidebar): use leading-tight on account block to prevent descender clipping with truncate
