Cursor's chat history showed as a single row labeled 'cursor' in
the dashboard because the global state.vscdb has no workspace
field on individual bubbles. The fix joins through Cursor's
per-workspace storage:
1. Walk ~/Library/Application Support/Cursor/User/workspaceStorage/*
2. For each hash dir, read workspace.json -> folder URI
3. Open that dir's state.vscdb, read
ItemTable['composer.composerData'] -> allComposers list
4. Build Map<composerId, folder URI>
5. emit one SessionSource per workspace plus a catch-all 'cursor'
source for composers that did not register against any
workspace (multi-root workspaces, no-folder-open windows,
deleted workspaces with surviving global rows)
The parser decodes source.path's #cursor-ws= tag, filters the
parsed bubbles to the composerIds that belong to this workspace,
and yields only those. The orphan-tag source negates the filter so
it captures every composer not in any workspace.
In passing, fix a real bug in the old code: parseBubbles set
`sessionId: row.conversation_id ?? 'unknown'`, but the JSON
`conversationId` field is empty in current Cursor builds, so every
call shipped with `sessionId: 'unknown'`. We now derive the
composer id from the row key (`bubbleId:<composerId>:<bubbleUuid>`)
which is what the workspace map joins on. The old behavior masked
the bug because every call went into a single 'cursor' project
anyway; with per-workspace bucketing the bug becomes load-bearing.
Cache version bumped 2 -> 3 to invalidate caches that still record
'unknown' as the session id.
Live-tested against my real 1.9 GB Cursor DB: the single 'cursor'
row with 1904 calls / $4.08 now breaks into 5 workspaces plus an
orphan bucket, totals reconcile exactly. 8 fixture-based tests
cover multi-workspace routing, orphan filtering, legacy bare DB
path backwards compat, multi-root workspace skip, vscode-remote
URI slugification, and total reconciliation across all sources.
Full suite: 46 files, 653 tests passing.
