* feat(studio): add S3 dataset configuration foundation (#4539)
Add foundational types and configuration for S3 bucket dataset loading:
- Add S3Config type to frontend training types
- Add S3Config Pydantic model to backend training models
- Add "s3" as a DatasetSource option
- Add s3Config state and setS3Config action to training config store
- Add i18n translations for S3 configuration (English and Chinese)
This provides the type definitions and UI text for S3 integration.
Full implementation requires boto3 dependency and data loading logic.
Refs: #4539
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Wire S3 config into training pipeline and prevent secrets persistence
- Pass s3_config from request into training_kwargs so it flows to training subprocess
- Add s3Config to NON_PERSISTED_STATE_KEYS to prevent AWS secrets from being
saved to localStorage
Addresses code review feedback on PR #5951.
* Exclude S3 config from database persistence to protect secrets
Filter out s3_config (which contains secret_access_key) from the
config_json stored in training_runs table, preventing AWS credentials
from being persisted to disk.
Addresses P1 security feedback on PR #5951.

* Re-raise HTTPException in start_training and defer s3 DatasetSource widening for PR #5951
* Redact s3_config from W&B run config and accept camelCase S3 credential aliases for PR #5951
* feat(studio): implement S3 dataset loading end-to-end
Builds the actual S3 loader on top of the hardened #5951 foundation,
turning the 501-gated scaffold into a working dataset source.
Backend:
- Add core/training/s3_dataset.py: lists and downloads supported dataset
files (parquet/json/jsonl/csv) from an S3 bucket to a temp dir, using
IAM-role or access-key credentials. boto3 is imported lazily (optional dep).
- Wire s3_config into UnslothTrainer.load_and_format_dataset (downloads then
reuses the existing local-file path) and thread it through worker.py.
- Replace the 501 "not implemented" gate with a boto3-availability guard so
S3 works when boto3 is present and fails clearly when it is not.
- Add boto3 to studio.txt requirements.
- Add tests/test_s3_dataset.py (8 tests) covering download/filtering,
collisions, missing-boto3, and S3Config camelCase/IAM validation.
Frontend:
- Widen DatasetSource to include "s3"; add s3_config to the training payload
type and mapper; add an S3 validation branch and selectS3Source store action.
- Add s3-config-form.tsx (bucket/region/prefix/keys/IAM toggle) reusing the
existing studio.dataset.s3.* i18n strings.
- Add a Hugging Face / Local / Amazon S3 source toggle in dataset-section;
the S3 config card replaces the dataset combobox when S3 is selected.
- Fix DatasetPreviewDialog to accept the widened DatasetSource type.

Adds a self-contained RAG stack to Studio: knowledge bases with chunked indexing, hybrid (dense + lexical) retrieval, and an automatic first-pass context inject into chat. Embeddings run through a local llama-server GGUF backend (default unsloth/bge-small-en-v1.5-GGUF) with a sentence-transformers fallback. The chat tool loop gains a search_knowledge_base tool, a per-turn re-search cap, and source citation, layered on top of the shared ToolLoopController.
Trim and tighten code comments and docstrings across the repository. Comment-only: every changed file verified code-identical to main via AST/token comparison.
Trim and tighten code comments and docstrings across studio/ Python. Comment-only: every changed file verified code-identical to main via AST/token comparison.
Raise ruff line-length to 100 and extend the local pre-commit format pipeline (def-signature magic-comma normalization, short multi-line assert collapse, kwarg '=' spacing, blank-line-after-short-import removal, adjacent string-literal / f-string+plain merge, redundant-pass pruning). Every transform re-checks the file AST and is dropped if it would differ; the whole-repo reformat is verified AST-identical per file and idempotent.

* Studio: manage chat history with projects
Group chats into projects with a dedicated projects page and route.
Sidebar shows recents with per-row actions and a vertical more-vertical
menu, and the sidebar scrollbar stays hidden so rows never shift on
hover. Includes chat settings and composer refinements.
* Studio: projects sidebar and breadcrumb polish
Sidebar:
- Remove the Compare nav item.
- Widen the sidebar to match the projects layout.
- Replace the scroll-gated bottom fade with a static fade pinned above
the profile box, so it no longer attaches to Recents or lags the
collapse and expand animation.
Topbar breadcrumb (chat-page):
- On a project landing show "Projects" linking to the projects list.
- Inside a project chat show the project name and chat title, with the
project name linking back to that specific project page.
- Drop the divider between the model selector and the breadcrumb.
* Studio: make project workspace delete test cross-platform
test_chat_project_delete_files_removes_workspace rooted the project under
pytest tmp_path, which resolves to /private/tmp on macOS. The workspace
delete guard refuses paths under the system denylist by design, so the
test passed on Linux CI but failed on macOS.
Add a workspace_projects_home fixture that keeps tmp_path on Linux and
Windows (CI unchanged) and falls back to a home subdir only when the temp
root is on the platform denylist. Derive the workspace path from the
created project so it tracks the projects home.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: satisfy import-hoist check for new path re-exports
documents_root and project_workspaces_root are re-exported from
utils.paths but only referenced as __all__ string literals, which the
import-hoist safety net does not count as a use. It flagged the two newly
added re-exports as unused imports and failed Source lint.
Name-load both via a module-level _REEXPORTED tuple so the check sees
them used. No behaviour change; consumers still import them from
utils.paths.
* fix: avoid projects empty-state flash
* fix: batch chat search indexing
* Studio: polish chat sidebar, run settings, and search
- Use the native OS scrollbar for the chat sidebar, Run settings panel, and chat search list instead of a custom scrollbar
- Highlight the active run in the sidebar and keep chat search available during training
- Stop the training log view from replaying when navigating back to a run
- Rename the chat settings panel to Run settings and align its toggle icon and position
- Tighten heading and sidebar letter spacing and lighten the Train and Recents labels
- Match the search dialog corner style across light and dark and drop the stray border
- Make the MCP Servers section header plain text instead of a link
- Remove a stray .orig backup file
* studio/frontend: restore Compare entry point in the sidebar
The chat-projects sidebar redesign dropped the Compare nav item and moved
it to thread-sidebar.tsx, which is not imported or rendered anywhere. That
left no way for a user to start a new model comparison (enterCompare only
fired from the guided tour and the training handoff), and broke the
Compare/Recipes/Export UI smoke test that clicks [data-tour="chat-compare"].
Re-add the Compare NavItem to the New Chat / Search group, carrying
data-tour="chat-compare" and the same new-comparison navigation as before.
* studio/frontend: use Unsloth green for the fallback profile avatar
Switch the initials-avatar background from blue to #14b789 so the sidebar
and edit-profile avatar match the Unsloth brand colour.
* studio/frontend: turn project breadcrumb into a project switcher dropdown
* studio/frontend: stop project card kebab clicks from opening the project
* studio/frontend: hide project switcher outside projects
* studio/frontend: stabilize project switcher loading

* Scope chat-history rows by subject; fix hijack, clear-confirm, hydrate race
Backend storage and routes:
- chat_threads / chat_messages / chat_settings carry a NOT NULL subject
column with composite PRIMARY KEY (id, subject). Two authenticated
identities can no longer see or wipe each other's data.
- Pre-existing rows on an existing studio.db migrate under sentinel
subject __legacy_unscoped__ via rename + rebuild + copy; single-user
installs see no behavior change.
- ON CONFLICT(id, subject) DO UPDATE ... WHERE chat_messages.thread_id =
excluded.thread_id refuses cross-thread re-parenting via upsert.
upsert_chat_message + sync_chat_messages now raise
ChatMessageThreadMismatch which the routes map to HTTP 409.
- replace_thread_messages rejects body messages whose threadId does not
match the URL thread (HTTP 400) instead of silently rewriting them.
- DELETE /api/chat requires ?confirm=true, returns row count, logs the
subject and count.
- upsert_chat_settings_merge does read + deep-merge + write inside a
single BEGIN IMMEDIATE so concurrent writers no longer drop each
other's updates. The route delegates to this helper.
- New POST /api/chat/messages:batch returns {thread_id -> messages[]}
for many threads in one HTTP call. Subject-scoped. Unknown ids return
empty lists instead of 404 so the sidebar/search caller can rebuild
atomically.
Frontend:
- chat-runtime-store: hydrate-failure catch sets settingsHydrated:true
so a transient backend blip no longer permanently disables
persistence. setParams bumps inferenceParamMutationVersions
unconditionally so a slow hydration response cannot clobber a
pre-hydrate user edit. saveSettingsPatch replaces the serial chain
with a debounced pendingPatch + deep merge; flush on beforeunload.
- chat-history-storage: clearStoredChats returns ClearStoredChatsResult
distinguishing backend / legacy / both outcomes.
listStoredChatThreadsWithMessages uses the batched fetch (one HTTP
call) instead of Promise.all per-thread; legacy Dexie fallback only
fires when the batch result is empty.
- chat-api: batchListChatMessages with graceful 404 / 405 fallback to
per-thread listChatMessages for older servers.
- chat-thread-tombstones: store {id, deletedAt} tuples with 90-day GC
and a 5000-entry cap so localStorage stays bounded. Back-compat reads
pre-fix plain strings. Adds removeChatThreadTombstones (rollback) and
clearAllChatThreadTombstones (post-legacy-purge clean-up).
- use-chat-sidebar-items: deleteChatItem tombstones synchronously
BEFORE the backend round-trip and rolls back on failure (restores
pre-PR optimistic UX). 300 ms trailing debounce on
CHAT_HISTORY_UPDATED_EVENT plus requestSeq guard so stream-time event
bursts produce at most one fetch per quiet window.
Tests:
- studio/backend/tests/pr5272_sim/ adds 64 regression tests covering
schema migration from pre-fix shape, subject scoping, cross-thread
hijack, bulk-replace mismatch, clear-confirm, concurrent settings,
unicode + 2MB content + SQL-injection-safe binding, chunking
boundary at 900 and 901 ids, batched endpoint (multi-subject + 1200
ids + per-thread order), and grep contracts for the frontend patches.
test_chat_history_storage.py updated to pass subject.
Verified locally on Linux + macOS + Windows GitHub Actions runners
(staging fork): 64 pass + 2 from the PR's own backend test on all
three OSes.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Drop subject scoping and clear-confirm gate (Studio is single-user)
Per maintainer feedback: subject scoping, cross-thread message hijack
guard, and DELETE /api/chat ?confirm=true gate are unnecessary because
Studio is intentionally single-user (the client already shows a confirm
dialog before clear-all).
This commit reverts those backend changes and keeps only the
non-multi-user pieces from the earlier fix commit:
- studio_db.py: restored to pre-fix shape; adds upsert_chat_settings_merge
which does atomic read + deep-merge + write under BEGIN IMMEDIATE so
two concurrent slider drags cannot drop one another's updates.
- routes/chat_history.py: restored; put_settings now calls the atomic
merge instead of doing the read-merge-write across three separate
connections. Adds POST /api/chat/messages:batch to collapse the
sidebar/search rebuild from N round-trips to 1.
- frontend/api/chat-api.ts: align batchListChatMessages request and
response keys with the backend (threadIds / messagesByThreadId).
- tests/test_chat_history_storage.py: add atomic-merge concurrency test,
deep-merge nested-key test, and 901-id chunking-boundary test.
- Drop the pr5272_sim test directory (those tests covered the reverted
subject-scoping/hijack/confirm behavior).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix sidebar delete crash, keepalive on settings beforeunload flush, search rebuild race
Two correctness bugs and one perf race surfaced by a fresh code review of
the prior fix commit:
- chat-api.ts: notifyChatHistoryUpdated was declared as a non-exported
function, but use-chat-sidebar-items.ts imports it. The import would
fail tsc with TS2305 and at runtime the optimistic-delete and
delete-failure rollback paths would both throw.
- chat-runtime-store.ts + chat-settings-api.ts + chat-settings-storage.ts:
the beforeunload settings flush is now actually keepalive. Without it
the browser cancels the in-flight PUT on tab close, so the last slider
drag is silently dropped (which is exactly the case the
debounce+beforeunload combination was meant to protect against).
- use-chat-search-index.ts: rebuilds now coalesce with a 300ms trailing
debounce and discard out-of-order responses via a requestSeq guard.
Matches the sibling pattern in use-chat-sidebar-items.ts so two rapid
CHAT_HISTORY_UPDATED_EVENTs (run-start + run-end save during a turn)
cannot land with stale data winning.
- chat-thread-tombstones.ts: drop dead clearAllChatThreadTombstones with
no call sites; Dexie is never wiped so the function has no use.

* chat: server-side ledger so legacy Dexie import is recoverable
The boolean localStorage sentinel
(unsloth_chat_legacy_imported_to_studio_db) made importLegacyChatsIfNeeded
non-recoverable: deleting studio.db while the browser keeps the flag
silently hides every legacy Dexie thread from the sidebar (verified by
the 3-GPU validation probe; matches the third review comment on PR
#5272). Same trap fires for browser-profile sync to a fresh machine
and any other path that wipes studio.db while keeping IndexedDB.
Source of truth moves into studio.db itself via a new
chat_legacy_import_log table keyed by legacy thread id. The ledger
disappears together with studio.db, so the next launch re-runs the
import from whatever Dexie still holds. localStorage stays as a
per-session perf hint only.
Performance, all bounded by the three new fast-paths before any
backend work:
A) localStorage hint says "imported earlier in this session" -- 0
network, ~0 ms. Covers the warm sidebar mount.
B) indexedDB.databases() reports no "unsloth-chat" DB -- 0 network,
~1 ms. Covers every new user who never had the old browser-only
Studio (the common case after launch).
C) db.threads.count() + db.messages.count() are both 0 -- 0 network,
~5 ms. Covers returning users who migrated long ago and Dexie was
never repopulated.
Only when all three miss does the code talk to the backend
(GET /api/chat/import-ledger -> diff vs Dexie -> existing import path
-> POST /api/chat/import-ledger to record what was just imported).
Per-thread tracking is enough because Dexie is read-only after this
PR; a thread's message set does not grow.
Backend deployments that predate the import-ledger routes are
handled transparently: the client treats 404/405 as an empty ledger
and re-runs the (idempotent via UPSERT) import on next launch.
Changes:
- storage/studio_db.py: new chat_legacy_import_log table (WITHOUT
ROWID, PK on legacy_thread_id) + list_chat_legacy_import_log() +
record_chat_legacy_import_log() (idempotent batch UPSERT).
- routes/chat_history.py: GET + POST /api/chat/import-ledger with the
obvious request/response models.
- frontend api/chat-api.ts: listChatImportLedger() (returns a Set for
O(1) diff) + recordChatImportLedger(), both with 404/405 fallback.
- frontend utils/chat-history-storage.ts: importLegacyChatsIfNeeded
gains three fast-paths, ledger fetch on the slow path, and writes
the ledger after a successful import. The localStorage helper is
unchanged on the surface; it just stops being authoritative.
- tests: 5 new test_legacy_import_log_* cases (empty default, record
+ list round-trip, idempotency, input dedup, empty/null ignore).
All 9 pre-existing tests still pass.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Make the legacy-import recovery actually recoverable
The previous commit added a server-side ledger to make Dexie -> studio.db
import recoverable after a studio.db wipe, but the localStorage perf hint
still short-circuited the import gate before the ledger was ever consulted.
After a wipe, the hint stayed "true" and the bulk re-import never ran -- the
ledger sat empty and only the per-thread lazy materialize-on-continue path
restored data.
Changes:
- Remove the localStorage short-circuit from importLegacyChatsIfNeeded so
the ledger is checked on every fresh tab. legacyChatImportPromise keeps
the per-session cache; the hint now only matters for the listing paths.
- Batch the slow path: one db.messages.where().anyOf().toArray() and one
batchListChatMessages() instead of 2N round-trips. At 1k threads this
drops a multi-second blocking import to a single request pair.
- recordChatImportLedger returns {accepted, inserted, supported}. The
localStorage hint is only flipped when supported is true, so old
backends (404 / 405 / 501) no longer permanently poison recovery.
- Ledger backfill: threads already present in chat_threads but missing
from the ledger now get added too, so old-FE-then-new-FE deployments
don't redo the diff every launch.
- Backend response field renamed recorded -> {accepted, inserted}.
accepted is the deduped non-empty input count; inserted is the rows
actually new (via INSERT ... RETURNING). Bounded by Field(max_length=
10_000) on the request payload.
- Storage helpers renamed: chat_legacy_import_log -> chat_legacy_imports,
record_* -> upsert_* to match the existing noun/verb conventions.
- DEXIE_DB_NAME exported from db.ts; duplicate constant in
chat-history-storage.ts removed.
- 3 new route-level tests for /api/chat/import-ledger covering the
round-trip, the (accepted, inserted) split, and the 10k payload cap.
All 18 chat-history tests pass.

* 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

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

off-grid values like 1.051234 and FP residue from slider drags.
- Branch picker chevrons share the action bar's 32px height + 10px radius

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.

* feat: add scan_folders table and CRUD functions to studio_db
* feat: add scan folders API endpoints and integrate into model scan
* feat: add scan folders API client and update source types
* feat: add custom source to model filters and selector
* feat: add Model Folders section to chat settings sidebar
* style: fix biome formatting in ModelFoldersSection
* fix: address review findings for custom scan folders
empty string bypass, concurrent delete crash guard,
Windows case normalization, response_model on endpoints,
logging, deduplicated filter/map, module level cache for
custom folder models, consistent source labels, handleRemove
error surfacing, per folder scan cap
* fix: show custom folders section regardless of chatOnly mode
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* refactor: extract shared refreshLocalModelsList in pickers
* Harden custom scan folder validation and scanning
- Validate path exists, is a directory, and is readable before persisting
- Apply per-folder model cap during traversal instead of after (avoids
scanning millions of inodes in large directories)
- Wrap per-folder scan in try/except so one unreadable folder does not
break the entire /api/models/local endpoint for all callers
- Normalize case on Windows before storing so C:\Models and c:\models
dedup correctly
- Extend macOS denylist to cover /private/etc and /private/tmp (realpath
resolves /etc -> /private/etc, bypassing the original denylist)
- Add /boot and /run to Linux denylist
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Improve scan robustness and preserve Windows path casing
- Preserve original Windows path casing in DB instead of lowercasing
(normcase used only for dedup comparison, not storage)
- Catch PermissionError per child directory so one unreadable subdirectory
does not skip the entire custom folder scan
- Wrap list_scan_folders() DB call in try/except so a DB issue does not
break the entire /api/models/local endpoint
* fix: scan custom folders for both flat and HF cache layouts
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix Windows case-insensitive path dedup with COLLATE NOCASE
Use COLLATE NOCASE on the scan_folders.path column so that the UNIQUE
constraint correctly deduplicates C:\Models and c:\models on Windows
without lowercasing the stored path. Also use COLLATE NOCASE in the
pre-insert lookup query on Windows to catch existing rows with
different casing.
* Restore early-exit limit in _scan_models_dir for custom folders
Keep the limit parameter so _scan_models_dir stops iterating once
enough models are found, avoiding unbounded traversal of large
directories. The post-traversal slice is still applied after combining
with _scan_hf_cache results.
* feat: scan custom folders with LM Studio layout too
* Fix custom folder models being hidden by dedup
Custom folder entries were appended after HF cache and models_dir
entries. The dedup loop kept the first occurrence of each model id,
so custom models with the same id as an existing HF cache entry were
silently dropped -- they never appeared in the "Custom Folders" UI
section.
Use a separate dedup key for custom-source entries so they always
survive deduplication. This way a model can appear under both
"Downloaded" (from HF cache) and "Custom Folders" (from the
user-registered directory) at the same time.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Harden LM Studio scan and fix COLLATE NOCASE on Linux
- Add per-child and per-publisher OSError handling in _scan_lmstudio_dir
so one unreadable subdirectory does not discard the entire custom
folder's results
- Only apply COLLATE NOCASE on the scan_folders schema on Windows where
paths are case-insensitive; keep default BINARY collation on Linux
and macOS where /Models and /models are distinct directories
* Use COLLATE NOCASE in post-IntegrityError fallback SELECT on Windows
The fallback SELECT after an IntegrityError race now uses the same
case-insensitive collation as the pre-insert check, so a concurrent
writer that stored the path with different casing does not cause a
false "Folder was concurrently removed" error.

* feat(db): add SQLite storage layer for training history
* feat(api): add training history endpoints and response models
* feat(training): integrate DB persistence into training event loop
* feat(ui): add training history views and card grid
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* fix(studio): address review issues in training history persistence
- Strip hf_token/wandb_token from config before SQLite storage
- Add UUID suffix to job_id for collision resistance
- Use isfinite() for 0.0 metric handling throughout
- Respect _should_stop in error event finalization
- Run schema DDL once per process, not per connection
- Close connection on schema init failure
- Guard cleanup_orphaned_runs at startup
- Cap _metric_buffer at 500 entries
- Make FLUSH_THRESHOLD a class constant
- Map 'running' to 'training' phase in historical view
- Derive LR/GradNorm from history arrays in historical view
- Fix nested button with div[role=button] in history cards
- Guard String(value) against null/undefined in config popover
- Clear selectedHistoryRunId on auto tab switch
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* fix(studio): address round-2 review findings across training backend and frontend
Backend (training.py):
- Move state mutation after proc.start() so a failed spawn does not wedge
the backend with is_training=True
- Create DB run row eagerly after proc.start() so runs appear in history
during model loading, not after first metric event
- Rewrite _flush_metrics_to_db() with snapshot-before-insert pattern to
preserve metrics arriving during the write and retain buffer on failure
- Guard eval_loss with float() coercion and math.isfinite(), matching the
existing grad_norm guard
- Increase pump thread join timeout from 3s to 8s to cover SQLite's
default 5s lock timeout
Frontend (studio-page.tsx):
- Fix history navigation: check isTrainingRunning instead of
showTrainingView in onSelectRun so completed runs are not misrouted
- Replace activeTab state + auto-switch useEffect with derived tab to
eliminate react-hooks/set-state-in-effect lint violation
Frontend (historical-training-view.tsx):
- Add explicit "running" branch to message ternary so running runs no
longer fall through to "Training errored"
- Derive loading from detail/error state and move cleanup to effect
return to eliminate react-hooks/set-state-in-effect lint violation
Frontend (progress-section.tsx):
- Derive stopRequested from isTrainingRunning && stopRequestedLocal to
eliminate react-hooks/set-state-in-effect lint violation and remove
unused useEffect import
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* fix(studio): resolve 3 remaining bugs from round-2 review
1. Stuck on Current Run tab [12/20]: Only force "current-run" tab when
isTrainingRunning is true, not when stale completed-run data exists.
After training ends, users can freely navigate to Configure.
2. Incomplete metric sanitization [7/20]: Apply float() coercion and
isfinite() guards to loss and learning_rate, matching the existing
pattern used by grad_norm and eval_loss. Prevents TypeError from
string values and NaN leaks into history arrays.
3. Stop button state leak across runs [10/20]: Add key={runtime.jobId}
to ProgressSection so React remounts it when a new run starts,
resetting stopRequestedLocal state.
* fix(studio): deduplicate loss/lr sanitization in training event handler
Reuse _safe_loss/_safe_lr from the progress update block instead of
re-sanitizing the same raw event values for metric history.
* fix(studio): restore loss > 0 guard to prevent eval steps injecting 0.0 into metric histories
Round-2/3 fixes relaxed the history append guard from `loss > 0` to
`loss is not None`, which let eval-only log events (where loss defaults
to 0.0) append fake zeros into loss_history and lr_history. Restore the
`loss > 0` check to match the worker's own has_train_loss gate. The
float() coercion and isfinite() sanitization from round-3 remain intact.
* fix(studio): resolve training history bugs — nullable loss/lr, tab nav, sparkline
