The bucket loop drops any created_at value that is not in yyyy-MM-dd HH:mm:ss, but this repository already writes ISO-8601 timestamps (for example src/brainlayer/store.py uses datetime.now(timezone.utc).isoformat()). In those cases formatter.date(from:) returns nil, so recent writes are silently excluded and PipelineState.derive can misreport active indexing as idle/enriching. Parse both timestamp formats (or normalize in SQL with datetime(created_at)) before computing buckets.
Useful? React with 👍 / 👎.

StatsCollector is @MainActor, and refresh() performs synchronous SQLite work (dashboardStats) directly on that actor. Because dashboardStats executes full-table count queries and recent-activity scans, startup and each change-triggered refresh can block menu-bar UI responsiveness on larger databases. Move the DB sampling to a background queue/task and only publish the computed values back on the main actor.

Addressed follow-up review findings: recent activity now normalizes ISO-8601 Python timestamps through SQLite datetime(), and the dashboard observer assigns its callback on its private queue to avoid the cross-thread write. @coderabbitai review |

🟢 Low BrainBar/BrainDatabase.swift:1296
recentActivityBuckets uses the shared static sqliteDateFormatter to parse dates. DateFormatter is not thread-safe, so concurrent calls from multiple threads can crash or corrupt the parsed dates. Since BrainDatabase is @unchecked Sendable, this is a data race. Consider creating a new DateFormatter per call, or using ISO8601DateFormatter which is thread-safe.
🚀 Reply "fix it for me" or copy this AI Prompt for your agent:
In file brain-bar/Sources/BrainBar/BrainDatabase.swift around line 1296:
`recentActivityBuckets` uses the shared static `sqliteDateFormatter` to parse dates. `DateFormatter` is not thread-safe, so concurrent calls from multiple threads can crash or corrupt the parsed dates. Since `BrainDatabase` is `@unchecked Sendable`, this is a data race. Consider creating a new `DateFormatter` per call, or using `ISO8601DateFormatter` which is thread-safe.
Evidence trail:
brain-bar/Sources/BrainBar/BrainDatabase.swift line 9: `final class BrainDatabase: @unchecked Sendable {`
brain-bar/Sources/BrainBar/BrainDatabase.swift line 1296: `private static let sqliteDateFormatter: DateFormatter = { ... }()`
brain-bar/Sources/BrainBar/BrainDatabase.swift line 713: `private func recentActivityBuckets(...)`
brain-bar/Sources/BrainBar/BrainDatabase.swift line 733: `let formatter = Self.sqliteDateFormatter`
Apple Foundation documentation confirms DateFormatter is not thread-safe.
