PR Summary

Medium Risk
Includes a DB migration and changes to file-upload name resolution plus table selection/indexing logic, which could affect data lookup and UI interactions if edge cases are missed. Also adds new analytics fields and Exa search parameters with relatively contained impact.

Overview
Improves observability and fixes chat-upload VFS collisions. Adds workspace_files.display_name with a partial unique index per chat, updates chat-upload tracking to allocate collision-free display names (e.g. file (2).png), and switches VFS read/list/materialize flows to prefer displayName (with legacy fallback + normalized matching). Adds tests covering collision retries and legacy/normalized lookup.

Correlates task analytics with server request IDs. Extends useChat to surface the current trace/request id and fires a new task_request_started PostHog event; task_generation_aborted now optionally includes request_id, and server-side capture auto-injects request_id from request context when absent.

Extends tools/UI behavior. Adds Exa search date filters (start/endCrawlDate, start/endPublishedDate) across docs, block config, tool schema, and request body; increases log details panel max width ratio; and refactors tables to use row array indices/row IDs (not DB position) for selection/checkboxing and cell targeting, removing gap-row rendering and remapping selections across row reorder.

Greptile Summary

This PR bundles five focused improvements: a VFS upload deduplication fix for copilot chat, PostHog/copilot correlation via request_id, date filters for the Exa search tool, a logs-panel width increase, and a tables UI/DB position decoupling.

• VFS fix: Adds a display_name column and a partial unique index (chat_id, display_name) WHERE context = 'mothership' so concurrent uploads of files with the same name within a chat get collision-free suffixed paths, preventing stale-row reads by the LLM.
• PostHog correlation: Fires task_request_started with the W3C traceparent trace ID as request_id on both the mothership and copilot views; the server-side captureServerEvent auto-stamps the same request_id from request context, enabling server-client log correlation.
• Exa date filters: Adds startCrawlDate, endCrawlDate, startPublishedDate, endPublishedDate parameters (ISO 8601 strings) across the block config, tool config, type definitions, and docs.

Confidence Score: 4/5

Safe to merge — changes are well-isolated, the VFS deduplication path is covered by unit tests, and the DB migration is backward-compatible.

The VFS fix carefully handles race conditions by discriminating between two 23505 sources, and the migration adds only a nullable column with a partial index. The PostHog additions are fire-and-forget. The one gap — displayName not nulled out on file materialization — has no current functional impact.

apps/sim/lib/copilot/tools/handlers/materialize-file.ts warrants a second look for the displayName cleanup on workspace promotion.

Important Files Changed

Filename	Overview
apps/sim/lib/uploads/contexts/workspace/workspace-file-manager.ts	Core of the VFS fix: adds trackChatUpload with collision-free displayName allocation and correct 23505 discrimination between display-name vs. key-active index collisions.
apps/sim/lib/copilot/tools/handlers/materialize-file.ts	Correctly adopts displayName as the canonical workspace originalName on materialization; does not reset displayName to NULL when promoting to workspace context.
apps/sim/lib/copilot/tools/handlers/upload-file-reader.ts	Correctly resolves VFS names via displayName for new rows and originalName for legacy NULL rows; normalized segment fallback handles macOS U+202F filenames.
packages/db/migrations/0202_fuzzy_darkstar.sql	Adds nullable display_name column and partial unique index on (chat_id, display_name) scoped to mothership context; backward-compatible with legacy NULL rows.
apps/sim/lib/posthog/server.ts	Auto-stamps request_id from request context on server-side events when not already set, enabling server-client log correlation.
apps/sim/tools/exa/search.ts	Adds four date-filter parameters forwarded as-is to Exa API; consistent with existing string-pass-through pattern.
apps/sim/stores/logs/utils.ts	Increases log details panel max width ratio from 0.4 to 0.6; viewport-safe clamping logic unchanged.
apps/sim/app/workspace/[workspaceId]/tables/[tableId]/components/table/utils.ts	Introduces expandToDisplayColumns and buildHeaderGroups utilities to decouple UI display indices from DB row positions.
