* fix(duplicate): place duplicate outside locked container
When duplicating a block that's inside a locked loop/parallel,
the duplicate is now placed outside the container since nothing
should be added to a locked container.

* fix(duplicate): unlock all blocks when duplicating workflow
- Server-side workflow duplication now sets locked: false for all blocks
- regenerateWorkflowStateIds also unlocks blocks for templates
- Client-side regenerateBlockIds already handled this (for paste/import)

* fix code block disabled state, allow unlock from editor
* fix(lock): address code review feedback
- Fix toggle enabled using first toggleable block, not first block
- Delete button now checks isParentLocked
- Lock button now has disabled state
- Editor lock icon distinguishes block vs parent lock state
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): prevent unlocking blocks inside locked containers
- Editor: can't unlock block if parent container is locked
- Action bar: can't unlock block if parent container is locked
- Shows "Parent container is locked" tooltip in both cases
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): ensure consistent behavior across all UIs
Block Menu, Editor, Action Bar now all have identical behavior:
- Enable/Disable: disabled when locked OR parent locked
- Flip Handles: disabled when locked OR parent locked
- Delete: disabled when locked OR parent locked
- Remove from Subflow: disabled when locked OR parent locked
- Lock: always available for admins
- Unlock: disabled when parent is locked (unlock parent first)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(enable): consistent behavior - can't enable if parent disabled
Same pattern as lock: must enable parent container first before
enabling children inside it.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* docs(quick-reference): add lock block action
Added documentation for the lock/unlock block feature (admin only).
Note: Image placeholder added, pending actual screenshot.

* remove prefix square brackets in error notif
* add lock block image
* fix(block-menu): paste should not be disabled for locked selection
Paste creates new blocks, doesn't modify selected ones. Changed from
disableEdit (includes lock state) to !userCanEdit (permission only),
matching the Duplicate action behavior.

* refactor(workflow): extract block deletion protection into shared utility
Extract duplicated block protection logic from workflow.tsx into
a reusable filterProtectedBlocks helper in utils/block-protection-utils.ts.
This ensures consistent behavior between context menu delete and
keyboard delete operations.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* refactor(workflow): extend block protection utilities for edge protection
Add isEdgeProtected, filterUnprotectedEdges, and hasProtectedBlocks
utilities. Refactor workflow.tsx to use these helpers for:
- onEdgesChange edge removal filtering
- onConnect connection prevention
- onNodeDragStart drag prevention
- Keyboard edge deletion
- Block menu disableEdit calculation
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): address review comments for lock feature
1. Store batchToggleEnabled now uses continue to skip locked blocks
entirely, matching database operation behavior
2. Copilot add operation now checks if parent container is locked
before adding nested nodes (defensive check for consistency)
3. Remove unused filterUnprotectedEdges function
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(copilot): add lock checks for insert and extract operations
- insert_into_subflow: Check if existing block being moved is locked
- extract_from_subflow: Check if block or parent subflow is locked
These operations now match the UI behavior where locked blocks
cannot be moved into/out of containers.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): prevent duplicates inside locked containers via regenerateBlockIds
1. regenerateBlockIds now checks if existing parent is locked before
keeping the block inside it. If parent is locked, the duplicate
is placed outside (parentId cleared) instead of creating an
inconsistent state.
2. Remove unnecessary effectivePermissions.canAdmin and potentialParentId
from onNodeDragStart dependency array.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): fix toggle locked target state and draggable check
1. BATCH_TOGGLE_LOCKED now uses first block from blocksToToggle set
instead of blockIds[0], matching BATCH_TOGGLE_ENABLED pattern.
Also added early exit if blocksToToggle is empty.
2. Blocks inside locked containers are now properly non-draggable.
Changed draggable check from !block.locked to use isBlockProtected()
which checks both block lock and parent container lock.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(copilot): check parent lock in edit and delete operations
Both edit and delete operations now check if the block's parent
container is locked, not just if the block itself is locked. This
ensures consistent behavior with the UI which uses isBlockProtected
utility that checks both direct lock and parent lock.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(socket): add server-side lock validation and admin-only permissions
1. BATCH_TOGGLE_LOCKED now requires admin role - non-admin users with
write role can no longer bypass UI restriction via direct socket
messages
2. BATCH_REMOVE_BLOCKS now validates lock status server-side - filters
out protected blocks (locked or inside locked parent) before deletion
3. Remove duplicate/outdated comment in regenerateBlockIds
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* test(socket): update permission test for admin-only lock toggle
batch-toggle-locked is now admin-only, so write role should be denied.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(undo-redo): use consistent target state for toggle redo
The redo logic for BATCH_TOGGLE_ENABLED and BATCH_TOGGLE_LOCKED was
incorrectly computing each block's new state as !previousStates[blockId].
However, the store's batchToggleEnabled/batchToggleLocked set ALL blocks
to the SAME target state based on the first block's previous state.
Now redo computes targetState = !previousStates[firstBlockId] and applies
it to all blocks, matching the store's behavior.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(socket): add comprehensive lock validation across operations
Based on audit findings, adds lock validation to multiple operations:
1. BATCH_TOGGLE_HANDLES - now skips locked/protected blocks at:
- Store layer (batchToggleHandles)
- Collaborative hook (collaborativeBatchToggleBlockHandles)
- Server socket handler
2. BATCH_ADD_BLOCKS - server now filters blocks being added to
locked parent containers
3. BATCH_UPDATE_PARENT - server now:
- Skips protected blocks (locked or inside locked container)
- Prevents moving blocks into locked containers
All validations use consistent isProtected() helper that checks both
direct lock and parent container lock.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* refactor(workflow): use pre-computed lock state from contextMenuBlocks
contextMenuBlocks already has locked and isParentLocked properties
computed in use-canvas-context-menu.ts, so there's no need to look
up blocks again via hasProtectedBlocks.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): add lock validation to block rename operations
Defense-in-depth: although the UI disables rename for locked blocks,
the collaborative layer and server now also validate locks.
- collaborativeUpdateBlockName: checks if block is locked or inside
locked container before attempting rename
- UPDATE_NAME server handler: checks lock status and parent lock
before performing database update
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* added defense in depth for renaming locked blocks
* fix(socket): add server-side lock validation for edges and subblocks
Defense-in-depth: adds lock checks to server-side handlers that were
previously relying only on client-side validation.
Edge operations (ADD, REMOVE, BATCH_ADD, BATCH_REMOVE):
- Check if source or target blocks are protected before modifying edges
Subblock updates:
- Check if parent block is protected before updating subblock values
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): fetch parent blocks for edge protection checks and consistent tooltip
- Fixed edge operations to fetch parent blocks before checking lock status
- Previously, isBlockProtected checked if parent was locked, but the parent
wasn't in blocksById because only source/target blocks were fetched
- Now fetches parent blocks for all four edge operations: ADD, REMOVE,
BATCH_ADD_EDGES, BATCH_REMOVE_EDGES
- Fixed tooltip inconsistency: changed "Run previous blocks first" to
"Run upstream blocks first" in action-bar to match workflow.tsx
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* updated tooltip text for run from block
* fix(lock): add lock check to duplicate button and clean up drag handler
- Added lock check to duplicate button in action bar to prevent
duplicating locked blocks (consistent with other edit operations)
- Removed ineffective early return in onNodeDragStart since the
`draggable` property on nodes already prevents dragging protected
blocks - the early return was misleading as it couldn't actually
stop a drag operation
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix(lock): use disableEdit for duplicate in block menu
Changed duplicate menu item to use disableEdit (which includes lock
check) instead of !userCanEdit for consistency with action bar and
other edit operations.

millisecond precision was insufficient.
Changes:
- block-executor.ts: Use performance.now() for block execution timing
- engine.ts: Use performance.now() for overall execution timing
