Merged Z-Image checkpoints (e.g. models with LoRAs baked in) may bundle
text encoder weights (text_encoders.*) or other non-transformer keys
alongside the transformer weights. These cause load_state_dict() to fail
with strict=True. Instead of disabling strict mode, explicitly whitelist
valid ZImageTransformer2DModel key prefixes and discard everything else.
Also moves RAM allocation after filtering so it doesn't over-allocate
for discarded keys.

`get_token_permission` is deprecated and will be removed in huggingface_hub 1.0.
Use `whoami()` to validate the token instead, as recommended by the deprecation warning.

* Phase 1: Add multi-user database schema and authentication foundation (#6)
* Initial plan
* Add Phase 1: Database schema, authentication utilities, and user service
- Added dependencies: passlib[bcrypt], python-jose[cryptography], email-validator
- Created migration_25 for multi-user support database schema
- users table with authentication fields
- user_sessions, user_invitations, shared_boards tables
- Added user_id columns to boards, images, workflows, session_queue, style_presets
- Created system user for backward compatibility
- Implemented authentication utilities
- Password hashing and validation (password_utils.py)
- JWT token generation and verification (token_service.py)
- Implemented user service
- Abstract base class (users_base.py)
- SQLite implementation (users_default.py)
- Full CRUD operations for users
- Authentication and admin management
- Added comprehensive tests for all components
- All code passes ruff linting and mypy type checking
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Refactor user service to use transaction pattern and improve security documentation
- Changed all database operations to use self._db.transaction() context manager
- Follows the same pattern as other services like board_records
- Improves thread safety and transaction management
- Added detailed security warnings for the hardcoded JWT secret key
- Documented that it must be moved to config before production
- Fixed whitespace linting issues
- All tests still pass with the refactored code
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix system user email to use valid domain
- Changed system user email from system@invokeai.local to system@system.invokeai
- .local domains are rejected by email-validator as special-use/reserved
- All end-to-end tests now pass successfully
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix test failures: password length, migration chain, and table existence checks
- Fixed bcrypt 72-byte password limit by truncating long passwords in hash_password and verify_password
- Fixed test_migration_25 to use callback directly instead of migrator to avoid fragmented chain error
- Updated system user email assertion in test from @invokeai.local to @system.invokeai
- Added table existence checks for boards, images, workflows, and session_queue before altering them
- This prevents "no such table" errors when migration runs in environments without all tables

- Simplified password truncation logic in password_utils.py for better clarity
- Ensured UTF-8 decoding handles truncated bytes properly with errors="ignore"
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* chore(uv): updated uv lockfile
* Fix bcrypt password length errors by configuring passlib properly
- Added bcrypt__relax_truncate_checks=True to CryptContext to prevent errors on long passwords
- Removed min_length=8 constraint from pydantic models to allow service-level validation
- Service-level validation provides better error messages and more control
- Manual truncation code kept as safety net for passwords >72 bytes
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix bcrypt parameter name: use truncate_error instead of relax_truncate_checks
- Changed bcrypt__relax_truncate_checks=True to bcrypt__truncate_error=False
- The correct passlib parameter is truncate_error (not relax_truncate_checks)
- Setting it to False allows passwords >72 bytes without raising an error

Fix token forgery test to properly decode and modify JWT payload
The test was attempting to modify the JWT payload by string replacement on the
base64-encoded data, which doesn't work since "false" doesn't appear literally
in the base64 encoding. Fixed to:
- Properly decode the base64 payload
- Parse the JSON
- Modify the is_admin field
- Re-encode the payload
- Create a forged token with the modified payload and original signature
- Verify it's rejected with 401 status
This properly tests that JWT signature verification prevents token forgery.

Fix test_verify_expired_token timing issue
Increased token expiration from 10ms to 100ms and wait time from 20ms to 200ms
to make the test more reliable. The previous timing was too tight and could
cause race conditions where the token hadn't actually expired yet when verified.
This ensures the test reliably validates that expired tokens are properly rejected.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
Fix token verification to properly validate signatures and expiration
The verify_token() function was not explicitly enabling JWT verification options,
causing it to accept expired tokens and tokens with modified signatures/payloads.
Fixed by explicitly setting verification options:
- verify_signature: True (reject modified tokens)
- verify_exp: True (reject expired tokens)
- verify_nbf: True (verify "not before" claim)
- verify_iat: True (verify "issued at" claim)
- verify_aud: False (we don't use audience claims)
Also added catch-all exception handler for other validation errors.
This ensures all token security tests pass properly.

Revert to default python-jose verification behavior
Removed explicit options parameter from jwt.decode() call since python-jose
verifies signatures and expiration by default. The explicit options may have
been causing issues or conflicts with the library's default behavior.
Added comments clarifying that python-jose defaults are secure and handle
verification properly. Need user to test and provide debugging output if
issues persist.

Fix JWT expiration verification for python-jose 3.5.0
python-jose 3.5.0 has a bug where expiration verification doesn't work properly
by default. The jwt.decode() function is not rejecting expired tokens even when
they should be rejected.
Workaround implemented:
1. First, get unverified claims to extract the 'exp' timestamp
2. Manually check if current time >= exp time (token is expired)
3. Return None immediately if expired
4. Then verify signature with jwt.decode() for tokens that aren't expired
This ensures:
- Expired tokens are properly rejected
- Signature verification still happens for non-expired tokens
- Modified tokens are rejected due to signature mismatch
All three failing tests should now pass:
- test_verify_expired_token
- test_verify_token_with_modified_payload
- test_token_signature_verification
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix race condition in token verification - verify signature before expiration
Changed the order of verification in verify_token():
1. First verify signature with jwt.decode() - rejects modified/forged tokens
2. Then manually check expiration timestamp
Previous implementation checked expiration first using get_unverified_claims(),
which could cause a race condition where:
- Token with valid payload but INVALID signature would pass expiration check
- If expiration check happened to return None due to timing, signature was never verified
- Modified tokens could be accepted intermittently
New implementation ensures signature is ALWAYS verified first, preventing any
modified tokens from being accepted, while still working around the python-jose
3.5.0 expiration bug by manually checking expiration after signature verification.
This eliminates the non-deterministic test failures in test_verify_token_with_modified_payload.

* Fix model manager UI visibility in single-user mode
Model manager UI for adding, deleting and modifying models is now:
- Visible in single-user mode (multiuser: false, the default)
- Hidden in multiuser mode for non-admin users
- Visible in multiuser mode for admin users
Created useIsModelManagerEnabled hook that checks multiuser_enabled status
and returns true when multiuser is disabled OR when user is admin.
Updated all model manager components to use this hook instead of direct
is_admin checks.

* Fix test_data_isolation to enable multiuser mode
Added fixture to enable multiuser mode for data isolation tests, similar to other auth tests.

* Redirect login and setup pages to app in single-user mode
When multiuser mode is disabled, the LoginPage and AdministratorSetup components now redirect to /app instead of showing the login/setup forms. This prevents users from being stuck on the login page after browser refresh in single-user mode.

* Fix test_auth.py to initialize JWT secret
Added setup_jwt_secret fixture to test_auth.py to initialize the JWT secret before running auth tests. This fixture was missing, causing token creation/verification to fail in auth router tests.

* Prevent login form flash in single-user mode
Show loading spinner instead of login/setup forms when multiuser mode is disabled or when redirecting is about to happen. This prevents the unattractive flash of the login dialog when refreshing the page in single-user mode.

* Fix board and queue operations in single-user mode
Changed boards, session_queue, and images routers to use CurrentUserOrDefault instead of CurrentUser. This allows these endpoints to work without authentication when multiuser mode is disabled (default), fixing the issue where users couldn't create boards or add jobs to the queue in single-user mode.

* Add user management utilities and rename add_user.py
Created three user management scripts in the scripts/ directory:
- useradd.py (renamed from add_user.py) - add users with admin privileges
- userdel.py - delete users by email address with confirmation
- usermod.py - modify user details (name, password, admin status)
All scripts support both CLI and interactive modes for flexibility.

* Add userlist.py script for viewing database users
Created scripts/userlist.py to display all users in the database. Supports:
- Table format (default): Shows ID, email, display name, admin status, and active status
- JSON format (--json flag): Outputs user data as JSON for scripting/automation
Example usage:
python scripts/userlist.py # Table view
python scripts/userlist.py --json # JSON output

* Fix test_boards_multiuser.py test failures
Fixed test failures caused by ApiDependencies.invoker not being set properly:
- Added setup_jwt_secret fixture to initialize JWT secret for token generation
- Added enable_multiuser_for_tests fixture that sets ApiDependencies.invoker as a class attribute
- Updated tests to use enable_multiuser_for_tests fixture to ensure ApiDependencies is properly configured
- Removed MockApiDependencies class approach in favor of directly setting the class attribute
This fixes the AttributeError and ensures all tests have the proper setup.

* Fix userlist.py SqliteDatabase initialization
Fixed AttributeError in userlist.py where SqliteDatabase was being passed the config object instead of config.db_path. The constructor expects a Path object (db_path) as the first argument, not the entire config object.

* Fix test_boards_multiuser.py by adding app_settings service to mock
Added AppSettingsService initialization to the mock_services fixture in tests/conftest.py. The test was failing because setup_jwt_secret fixture expected mock_invoker.services.app_settings to exist, but it wasn't being initialized in the mock services.

* bugfix(scripts): fix crash in userlist.py script
* Fix test_boards_multiuser.py JWT secret initialization
Fixed setup_jwt_secret fixture to call set_jwt_secret() directly instead of trying to access non-existent app_settings service. Removed incorrect app_settings parameter from InvocationServices initialization in tests/conftest.py since app_settings is not an attribute of InvocationServices.

* Fix CurrentUserOrDefault to require auth in multiuser mode
Changed get_current_user_or_default to raise HTTP 401 when multiuser mode is enabled and credentials are missing, invalid, or the user is inactive. This ensures that board/queue/image operations require authentication in multiuser mode while still working without authentication in single-user mode (default).

* chore(front & backend): ruff and lint
* Add AdminUserOrDefault and fix model settings in single-user mode
Created AdminUserOrDefault dependency that allows admin operations to work without authentication in single-user mode while requiring admin privileges in multiuser mode. Updated model_manager router to use AdminUserOrDefault for update_model_record, update_model_image, and reidentify_model endpoints. This fixes the "Missing authentication credentials" error when saving model default settings in single-user mode.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix model manager operations in single-user mode
Changed all model manager endpoints from AdminUser to AdminUserOrDefault to allow model installation, deletion, conversion, and cache management operations to work without authentication in single-user mode. This fixes the issue where users couldn't add or delete models in single-user mode.

* Fix syntax error in model_manager.py
Added Depends(AdminUserOrDefault) to all AdminUserOrDefault dependency parameters to fix Python syntax error where parameters without defaults were following parameters with defaults. Imported Depends from fastapi.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix FastAPI dependency injection syntax error
Removed type annotations from AdminUserOrDefault dependency parameters. FastAPI doesn't allow both Annotated type hints and = Depends() default values together. Changed from `_: AdminUserOrDefault = Depends(AdminUserOrDefault)` to `_ = Depends(AdminUserOrDefault)` throughout model_manager.py.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix delete_model endpoint parameter annotation
Changed delete_model endpoint to use Annotated[str, Path(...)] instead of str = Path(...) to match FastAPI's preferred syntax and fix the 422 Unprocessable Entity error when deleting models in single-user mode.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix parameter annotations for all AdminUserOrDefault endpoints
Changed all endpoints using AdminUserOrDefault from old syntax (key: str = Path(...)) to FastAPI's preferred Annotated syntax (key: Annotated[str, Path(...)]). This fixes 422 Unprocessable Entity errors when updating model settings and deleting models in single-user mode. Updated endpoints: delete_model_image, install_model, install_hugging_face_model, and convert_model.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Revert to correct AdminUserOrDefault usage pattern
Reverted model_manager.py to state before commit c47af8f and reapplied AdminUserOrDefault correctly. Changed from `_: AdminUser` to `current_admin: AdminUserOrDefault` using the same pattern as boards.py (`current_user: CurrentUserOrDefault`). This fixes all 422 errors in single-user mode while maintaining proper admin authentication in multiuser mode.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix parameter order for AdminUserOrDefault in model manager
Moved current_admin: AdminUserOrDefault parameter before all parameters with default values in model_manager.py endpoints. Python requires parameters without defaults to come before parameters with defaults. Fixed 8 endpoints: delete_model, bulk_delete_models, delete_model_image, install_model, install_hugging_face_model, cancel_model_install_job, convert_model, and do_hf_login.

* fix: queue pause/resume buttons disabled in single-user mode (#83)
In single-user mode, currentUser is never populated (no auth), so
`currentUser?.is_admin ?? false` always returns false, disabling the buttons.
Follow the same pattern as useIsModelManagerEnabled: treat as admin
when multiuser mode is disabled, and check is_admin flag when enabled.

- Auth requirement tests for get, update, delete, and list_image_names
- Cross-user 403 forbidden tests (non-owner cannot access/modify/delete)
- Admin bypass tests (admin can access/update/delete any user's board)
- Board listing isolation test (users only see their own boards)

* Add FLUX.2 LOKR model support (detection and loading) (#88)
Fix BFL LOKR models being misidentified as AIToolkit format

* Fix BFL→diffusers key mapping for non-block layers in FLUX.2 LoRA/LoKR
BFL's FLUX.2 model uses different names than diffusers' Flux2Transformer2DModel
for top-level modules (embedders, modulations, output layers). The existing
conversion only handled block-level renames (double_blocks→transformer_blocks),
causing "Failed to find module" warnings for non-block LoRA keys like img_in,
txt_in, modulation.lin, time_in, and final_layer.

* WIP: Add FLUX.2 Klein LoRA support (BFL PEFT format)
Initial implementation for loading and applying LoRA models trained
with BFL's PEFT format for FLUX.2 Klein transformers.
Changes:
- Add LoRA_Diffusers_Flux2_Config and LoRA_LyCORIS_Flux2_Config
- Add BflPeft format to FluxLoRAFormat taxonomy
- Add flux_bfl_peft_lora_conversion_utils for weight conversion
- Add Flux2KleinLoraLoaderInvocation node
Status: Work in progress - not yet fully tested
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* feat(flux2): add LoRA support for FLUX.2 Klein models
Add BFL PEFT LoRA support for FLUX.2 Klein, including runtime conversion
of BFL-format keys to diffusers format with fused QKV splitting, improved
detection of Klein 4B LoRAs via MLP ratio check, and frontend graph wiring.
* feat(flux2): detect Klein LoRA variant (4B/9B) and filter by compatibility
Auto-detect FLUX.2 Klein LoRA variant from tensor dimensions during model
probe, warn on variant mismatch at load time, and filter the LoRA picker
to only show variant-compatible LoRAs.
* Chore Ruff
* Chore pnpm
* Fix detection and loading of 3 unrecognized Flux.2 Klein LoRA formats
Three Flux.2 Klein LoRAs were either unrecognized or misclassified due to
format detection gaps:
1. PEFT-wrapped BFL format (base_model.model.* prefix) was not recognized
because the detector only accepted the diffusion_model.* prefix.
2. Klein 4B LoRAs with hidden_size=3072 were misidentified as Flux.1 due to
a break statement exiting the detection loop before txt_in/vector_in
dimensions could be checked.
3. Flux2 native diffusers format (to_qkv_mlp_proj, ff.linear_in) was not
detected because the detector only checked for Flux.1 diffusers keys.
Also handles mixed PEFT/standard LoRA suffix formats within the same file.

* Fix bare except clauses and mutable default arguments
Replace bare `except:` with `except Exception:` in sqlite_database.py
and mlsd/utils.py to avoid catching KeyboardInterrupt and SystemExit,
which can prevent graceful shutdowns and mask critical errors (PEP 8
E722).
Replace mutable default arguments (lists) with None in
imwatermark/vendor.py to prevent shared state between calls, which
is a known Python gotcha that can cause subtle bugs when default
mutable objects are modified in place.
* add tests for mutable defaults and bare except fixes
* Simplify exception propagation tests
* Remove unused db initialization in error propagation tests
Removed unused database initialization in tests for KeyboardInterrupt and SystemExit.

* feat(z-image): add Z-Image Base (undistilled) model variant support
- Add ZImageVariantType enum with 'turbo' and 'zbase' variants
- Auto-detect variant on import via scheduler_config.json shift value (3.0=turbo, 6.0=zbase)
- Add database migration to populate variant field for existing Z-Image models
- Re-add LCM scheduler with variant-aware filtering (LCM hidden for zbase)
- Auto-reset scheduler to Euler when switching to zbase model if LCM selected
- Update frontend to show/hide LCM option based on model variant
- Add toast notification when scheduler is auto-reset
Z-Image Base models are undistilled and require more steps (28-50) with higher
guidance (3.0-5.0), while Z-Image Turbo is distilled for ~8 steps with CFG 1.0.
LCM scheduler only works with distilled (Turbo) models.
* Chore ruff format
* Chore fix windows path
* feat(z-image): filter LoRAs by variant compatibility and warn on mismatch
LoRA picker now hides Z-Image LoRAs with incompatible variants (e.g. ZBase
LoRAs when using Turbo model). LoRAs without a variant are always shown.
Backend loaders warn at runtime if a LoRA variant doesn't match the
transformer variant.
* Chore typegen

The FLUX.2 Klein transformer operates in BN-normalized latent space,
but init_latents from VAE encode were not being normalized before
being passed to the InpaintExtension. This caused a scale mismatch
when merging intermediate_latents (normalized) with noised_init_latents
(unnormalized), resulting in visible artifacts at mask blur boundaries.
Now normalize:
- init_latents_packed before passing to InpaintExtension
- noise_packed for correct interpolation in normalized space
- x (starting latents) for img2img/inpainting workflows

* feat(canvas): add raster layer blend modes and boolean operations submenu; support per-layer globalCompositeOperation in compositor; UI to toggle and select color blend modes (multiply, screen, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, hue, saturation, color, luminosity).
* feat(canvas): boolean ops submenu and UI polish
* (chore): prettier lint
* add icons to boolean submenu items
* add delete button for color blend operations
* move composite operation type and imports
* chore: pnpm eslint
* update blend modes order
* update default blend mode to 'color'
* add i18n for blend modes
* actually use translations for blend modes now
* move composite options into types.ts
* cleanup and comments
* update names
* move constant mapping out of function
* feat(ui): Refactor Blend Mode Implementation
- Blend Modes are not right click menu options anymore. Instead they rest above the layer panel as they do in other art programs readily available for each layer.
- Blend Modes have been resorted to match the listings of other art programs so users can avail their muscle memory.
- Blend Mode now defaults to `Normal` for each layer as it should.
- The extra layer operations have now been moved down to the `Operations Bar` at the bottom of the layer stack. This is to increase familiarity again with other art programs and also to make space for us in the top action bar.
- The Operations Bars operations have been resorted in order of usage that makes sense.
* fix: use source-over instead of normal
* fix: pixel fix for slightly offset action bar labels.
* feat(canvas): boolean raster merge creates new layer and disables sources
* (fix) lint errors
* remove extra typecast

* fix(flux2): Fix image quality degradation at resolutions > 1024x1024
This commit addresses severe quality degradation and artifacts when
generating images larger than 1024x1024 with FLUX.2 Klein models.
Root causes fixed:
1. Dynamic max_image_seq_len in scheduler (flux2_denoise.py)
- Previously hardcoded to 4096 (1024x1024 only)
- Now dynamically calculated based on actual resolution
- Allows proper schedule shifting at all resolutions
2. Smoothed mu calculation discontinuity (sampling_utils.py)
- Eliminated 40-50% mu value drop at seq_len 4300 threshold
- Implemented smooth cosine interpolation (4096-4500 transition zone)
- Gradual blend between low-res and high-res formulas
Impact:
- FLUX.2 Klein 9B: Major quality improvement at high resolutions
- FLUX.2 Klein 4B: Improved quality at high resolutions
- Baseline 1024x1024: Unchanged (no regression)
- All generation modes: T2I and Kontext (reference images)
Fixes: Community-reported quality degradation issue
See: Discord discussions in #garbage-bin and #devchat

* fix(flux2): Fix high-resolution quality degradation for FLUX.2 Klein
Fixes grid/diamond artifacts and color loss at resolutions > 1024x1024.
Root causes identified and fixed:
- BN normalization was incorrectly applied to random noise input
(diffusers only normalizes image latents from VAE.encode)
- BN denormalization must be applied to output before VAE decode
- mu parameter was resolution-dependent causing over-shifted schedules
at high resolutions (now fixed to 2.02, matching ComfyUI)
Changes:
- Remove BN normalization on noise input (not needed for N(0,1) noise)
- Preserve BN denormalization on denoised output (required for VAE)
- Fix mu to constant 2.02 for all resolutions (matches ComfyUI)
Tested at 2048x2048 with FLUX.2 Klein 4B

The ParamFluxDypePreset component was rendered twice in the FLUX
generation settings accordion, causing the DyPE dropdown to appear
both after the scheduler and after the guidance slider.

setting with hardcoded full denoising (start=0, end=1) in addOutpaint.
This caused denoising strength to be completely ignored whenever the
canvas bbox extended beyond the raster layer content, triggering outpaint
mode. The issue affected all model types (SDXL, SD1.5, FLUX, etc.).
Restore the original behavior by reading denoising_start/end from the
user's img2imgStrength setting via getDenoisingStartAndEnd().

When recalling an image that lacks `z_image_seed_variance_enabled` metadata
(e.g. older images), the toggle now defaults to off instead of retaining the
previous state.
* Switched to use v5.x gallery pagination design.
* Improved pagination UX and gallery grid calculation
* Minor bug fix
* Formatting...
* Fixed Jump to page input behavior and "Locate in gallery" logic.
* Changed Jump input field to select text on click for better UX.
Use useFlux1VAEModels() instead of useFluxVAEModels() in the FLUX VAE
selector, which was incorrectly returning both FLUX.1 and FLUX.2 VAEs.
Remove the now-unused useFluxVAEModels hook.

* fix(flux2): support Heun scheduler for FLUX.2 Klein models
FlowMatchHeunDiscreteScheduler does not support dynamic shifting parameters
(use_dynamic_shifting, base_shift, max_shift, etc.) or sigmas/mu in set_timesteps.
This caused FLUX.2 Klein to fail when using Heun scheduler.
- Create Heun scheduler with only num_train_timesteps and shift parameters
- Use num_inference_steps instead of sigmas for Heun's set_timesteps call
- Euler and LCM schedulers continue to use full dynamic shifting support
* fix(flux2): fix Heun scheduler detection using inspect.signature
The previous hasattr check for state_in_first_order failed because
the attribute doesn't exist before set_timesteps() is called. Now
using inspect.signature to check for sigmas parameter support,
matching the FLUX1 implementation.

* Implemented ordering for expanded iterators
* Update test_graph_execution_state.py
Added a test for nested iterator execution ordering. (Failing at commit time!)
* Filter invalid nested-iterator parent mappings in _prepare()
When a graph has nested iterators, some "ready to run" node combinations do not actually belong together. Previously, the scheduler would still try to build nodes for those mismatched combinations, which could cause the same work to run more than once. This change skips any combination that is missing a valid iterator parent, so nested iterator expansions run once per intended item.
* Fixed Collect node ordering
* ruff
* Removed ordering guarantees from test_node_graph.py
* Fix iterator prep and type compatibility in graph execution
Include iterator nodes in nx_graph_flat so iterators are prepared/expanded correctly. Fix connection type checks to allow subclass-to-base via issubclass. Harden iterator/collector validation to fail cleanly instead of crashing on missing edges. Remove unused nx_graph_with_data(). Added tests to verify proper functionality.
* feat(model_manager): add missing models filter to Model Manager
Adds the ability to view and manage orphaned model database entries
where the underlying files have been deleted externally.
Changes:
- Add GET /v2/models/missing API endpoint to list models with missing files
- Add "Missing Files" filter option to Model Manager type filter dropdown
- Display "Missing Files" badge on models with missing files in the list
- Automatically exclude missing models from model selection dropdowns
to prevent users from selecting unavailable models for generation
* fix(ui): enable Select All checkbox for missing models filter
The Select All checkbox was disabled when the missing models filter was
active because the bulk actions component didn't use the missing models
query data. Now it correctly uses useGetMissingModelsQuery when the
filter is set to 'missing'.
* test(model_manager): add tests for missing model detection and bulk delete
Tests _scan_for_missing_models and the unregister/delete workflow for
models whose files have been removed externally.
* Chore Ruff check
When switching between FLUX.2 (model-less reference images) and other
models that require IP adapter/Redux models, the reference image configs
were not being converted, leaving stale config types that hid or showed
the wrong UI controls.
