Summary by CodeRabbit

  • Bug Fixes
    • Improved conversation indexing, search, export, and workspace tabs for Cursor 3 conversation data, including conversations with headers stored separately.
    • Preserved bubble IDs containing colons when processing conversation messages.
    • Conversations without valid headers remain excluded from search results and exports.
    • Search indexes with outdated version information are now recognized as stale and rebuilt when needed.

Walkthrough

The change adds support for loading Cursor 3 conversation headers from composerConvHeaders when inline headers are empty. Export, search, and workspace parsing use those headers. Bubble ID extraction preserves colons. Search index validation checks the stored version.

Changes: Cursor conversation index support

Layer / File(s) Summary
Load and normalize conversation index data
utils/conversation_index.py, services/workspace_db.py, tests/test_conversation_index.py
Helpers load ordered conversation-header chunks, apply mapped headers when inline headers are empty, and extract bubble IDs without truncating colons. Tests cover chunk ordering, inline-header precedence, and bubble ID parsing.
Apply conversation headers to workspace composers
services/workspace_composer_scan.py, services/workspace_db.py, services/workspace_listing.py, services/workspace_tabs.py
Workspace parsing receives conversation-header maps. Composer queries include rows with empty inline header lists.
Apply conversation headers to export and search
services/export_engine.py, services/search.py, tests/test_export_exclusion_filtering.py, CHANGELOG.md
Export and search apply mapped headers before validating composer headers. The export test covers ordered chunk headers, colon-containing bubble IDs, and exclusion of a headerless draft.
Rebuild stale search indexes
services/search_index.py, tests/test_search_index.py
Search index usability requires a matching stored index version and fingerprint. Tests verify that an index with version 1 is rebuilt.

Runtime and CI compatibility

Layer / File(s) Summary
Constrain runtime dependency and CI runner
pyproject.toml, requirements.txt, requirements-lock.txt, .github/workflows/tests.yml
The runtime requirements constrain fonttools to versions below 4.66. The browser-XSS job uses Ubuntu 24.04, and the lock file updates five package pins.

Merge Risk: Minimal · up to 2a628

The previously identified export and Python 3.10 installation risks are resolved, and the remaining workspace behavior follows the repository’s documented performance contract.

Docstring coverage is 70.37% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 27 functions across 11 files.

Review comments at @services/search_index.py:
- Line 570: Update the rebuild decisions in ensure_search_index and
build_search_index to check the stored index version as well as the storage
fingerprint, using _stored_index_version and INDEX_VERSION. Ensure a version
mismatch triggers rebuilding even when the fingerprint matches, while preserving
the existing behavior for matching versions.

Review comments at @services/workspace_tabs.py:
- Line 693: Update the single-tab loading path around load_conv_header_map to
use a composer-scoped header loader, passing the selected composer’s identifier
so it reads only that composer’s headers. Retain load_conv_header_map for
summary and full-tab assembly.

Review comments at @utils/conversation_index.py:
- Line 90: Validate chunk header IDs when building headers from parsed entries:
retain only dictionaries whose bubbleId is a string, so invalid IDs cannot reach
bubble_map.get in _build_ide_export_bubbles.

A version-1 index with a matching fingerprint never rebuilt, so search stayed on the live scan. Opening one tab now reads only that composer's header rows, and non-string bubble ids are dropped before export. Refresh the lock file so the freshness check matches current pins.

fonttools 4.66 and later require Python 3.11, so the 3.10 matrix could not install the lock. Cap fonttools below 4.66 and run the Playwright job on Ubuntu 24.04, where Chromium 1.50 still installs.
