This PR is for moving the core of block-md off of relying on the block system so that it's pieces can be more reusable/composable and with the intention that we'll want to remove the block system in the future. There is some refactor around state (now living in a top level context for the most part) and updating how things are accessed and passed around. This PR also includes clean up and refactoring of some unused things (like the signal folder and an unused global location redirect signal).

Most logic and access remained the same since the intention of this PR was just a simple move off of blocks and further refactors/changes should be done in future PRs.


Note

Medium Risk
Large structural refactor across editor load/save, live comments, and collaboration UI with behavior intended to stay the same, so regressions in sync, comments, or hotkeys are plausible.

Overview
This PR moves the markdown/task document UI off block-scoped signals and stores onto a reusable MarkdownDocument surface with a shared context and createMarkdownDocumentState() (editor, comments, generation, params, permissions, document source). The block entrypoint becomes a thin adapter that wires block loader data, orchestrator methods, and permissions into that provider; Loro snapshot ingestion and scroll/notebook wiring live in MarkdownDocument / MarkdownDocumentContent instead of Block.tsx.

Comments and discussions drop commentStore and block resources in favor of document state + TanStack Query (useMarkdownCommentsQuery, cache updates, useCommentRealtime). Margin layout is created via createCommentLayout() per mount, and CommentMargin takes an explicit wideEnough prop rather than a global width signal.

Cross-cutting UX changes: offline/reconnecting sync status is a shared CollaborationStatusIndicator in the split header (replacing block-local CollabStatus); ] toggle side panel is registered once in SidePanel.Layout (removed from agent/email top bars). Saves and renames go through document mutations; draft-comment thread -1 still blocks saves. Share modals switch to ShareModal with metadata-driven permissions. Notebook loses the inline “Ask Macro / dispatch agent” side-panel section that lived in the editor column; AI content generation in the editor is stubbed pending a gateway port.

Summary by CodeRabbit

  • New Features

    • Added collaboration status indicators for disconnected and reconnecting states.
    • Added Markdown document downloads as .md or .json files.
    • Added task shortcuts for copying branch names and toggling the side panel.
    • Added document actions including sharing, chat, agent tools, and code actions.
  • Improvements

    • Improved comment and discussion handling across Markdown documents.
    • Improved editor state, permissions, saving, and document loading consistency.
    • Added support for Markdown documents, tasks, snippets, and skills through a unified experience.

Walkthrough

The pull request moves markdown editor state from block-scoped stores to a document-scoped context. It adds document state, snapshot ingestion, persistence, query-based comments, and shared collaboration handling. Markdown components and editor plugins consume the new state through context, props, or lexical context. Legacy signals, temporary redirect handling, and block-specific comment stores are removed. Side-panel hotkey registration and document toolbar construction move to shared hooks.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 6467e

Document adoption, saving, loading, AI dispatch, and generation can behave incorrectly in reachable workflows. These issues should be resolved before merge.

Use match for the realtime update dispatcher.

Replace this switch with an exhaustive match on incrementalUpdate.updateType. This makes new update variants a compile-time handling requirement.

Inline comments:
In `@apps/web/src/features/block-md/comments/commentLayout.ts`:
- Line 255: Update the layout effect’s active mark state access around
activeMarkIdsValue to track commentState.activeMarkIds instead of reading it
through untrack, so changes to the active mark rerun the effect and reposition
the layout for the newly selected thread.

In `@apps/web/src/features/block-md/comments/commentsResource.ts`:
- Line 68: Move the create, edit, and delete comment service-client calls
currently used by commentsResource into mutation hooks in
queries/markdown-comments.ts, including their related cache updates. Update
commentsResource to use those hooks instead of calling storageServiceClient
directly, preserving the existing mutation behavior and cache invalidation.

In `@apps/web/src/features/block-md/component/DispatchAgentMenu.tsx`:
- Line 169: Move the state.editor.md.editor lookup into the buildPrompt function
so it reads the current editor instance when the prompt is built, rather than
capturing it during component initialization. Ensure dispatch actions use that
latest editor to include document content after MarkdownEditor initializes.

In `@apps/web/src/features/block-md/component/InstructionsEditor.tsx`:
- Line 281: Update the arrayBuffer loading flow in InstructionsEditor so
rejections from source.file.arrayBuffer() are caught and routed to the existing
document-load or editor error state, while preserving setFileArrayBuffer for
successful reads.

In `@apps/web/src/features/block-md/component/MarkdownDocument.tsx`:
- Around line 240-245: Remount the Markdown block subtree when the adopted
document ID changes so all ID-bound state is recreated. Update the block
rendering flow around MarkdownDocumentContent/Block to use the current
documentId as the remount key, ensuring BlockContext, the Loro manager,
IDBSnapshotStore, and BrowserWALStore no longer retain the original ID.

In `@apps/web/src/features/block-md/component/MarkdownEditor.tsx`:
- Around line 949-951: Update the MarkdownEditor generation flow around
_generateContentCallback so GenerateMenu submissions invoke the available
generation request path and start actual generation instead of only setting
isGenerating; if that path remains unavailable, hide or disable GenerateMenu
until the connection-gateway port is complete.

In `@apps/web/src/features/block-md/queries/markdown-document-operations.ts`:
- Around line 21-23: Update the save-failure branch in the markdown mutation
operation around simpleSave so it throws the underlying error instead of logging
and returning. Preserve the existing success path, ensuring TanStack Query
receives a rejected promise when result.isErr() is true.
- Line 9: Refactor loadMarkdownCachedSnapshot and useTaskBranchNameHotkey so the
fetchCachedSnapshot and getDocumentBranchName service requests are accessed
through TanStack Query APIs in the queries package rather than called directly.
Preserve the existing returned data and hotkey clipboard behavior while routing
both network calls through the established query hooks or query functions.

Track active mark changes in the layout effect.

untrack prevents this effect from rerunning when activeMarkIds changes. Selecting another thread therefore does not reposition the layout around the new active mark until an unrelated layout dependency changes.

Remount the Markdown block when adoption changes its document ID.

adoptContentId keeps the existing mount and only updates split and orchestrator identity. Block creates BlockContext once with the original ID, so useBlockId() remains bound to that ID. MarkdownDocumentContent therefore keeps its Loro manager, IDBSnapshotStore, and BrowserWALStore attached to the original document while the mount is identified by the adopted ID.

Do not expose generation while its request path is disabled.

The callback discards _userRequest and only sets isGenerating to true. When GenerateMenu is enabled, a submitted prompt does not start generation.

Restore the generation request path. Otherwise, hide or disable GenerateMenu until the connection-gateway port is complete.

Route both service-client requests through TanStack Query.

The repository requires all service-client network calls to use TanStack Query in the queries package.

  • loadMarkdownCachedSnapshot directly calls storageServiceClient.fetchCachedSnapshot, which performs a dssFetch request.
  • useTaskBranchNameHotkey reaches copyBranchNameToClipboard, which directly calls storageServiceClient.getDocumentBranchName, which also performs a dssFetch request.

Move both requests behind TanStack Query APIs in the queries package. This is a contract refactor.

This branch returns a fulfilled promise after simpleSave fails. TanStack Query therefore records a successful mutation, and callers cannot detect or retry the failed save. Throw an error from this branch.

around lines 21 - 23, Update the save-failure branch in the markdown mutation
operation around simpleSave so it throws the underlying error instead of logging
and returning. Preserve the existing success path, ensuring TanStack Query
