Use portable file ownership for transcript reads

2026-09-24T14:20:04Z

Replace the Windows-only LLUniqueFile with std::unique_ptr and the existing LLFile::close deleter. This fixes the macOS compile failure while retaining automatic file closure on every exit. Windows Release build, 41 history tests, and repository hooks passed. macOS CI still needs to be rerun.

Share the exact-path transcript reader

2026-09-23T19:24:08Z

Delegate ordinary transcript reads to the same exact-path reader used by stitching. Let that reader own parsing and its file handle, removing the separate parser layer and duplicated open/close path. Keep ordinary privacy, filename and group fallback at the existing entry point. Require explicit read parameters and preserve full/bounded reads, EOF handling, BOM, newline, multiline and mention behavior. Compared 28 full/bounded read inputs and checked retained message contents.

Centralize history availability in the transcript query

2026-09-23T19:24:03Z

Make LLLogChat::isTranscriptExist apply the deletion gate and check both plaintext and direct service history. Restore its menu and profile callers to that existing query, removing their repeated policy and extra includes. Keep group history on the ordinary transcript path.

Simplify transcript worker ownership and publication boundaries

2026-09-23T19:24:01Z

Let the legacy worker own its filename and completion signal. Remove manual signal deletion and the unused thread accessor together with Preview's mutex; both loaders publish pages on the main loop. Keep save/delete exclusion and release it before notifying observers. Expose the captured-path reader directly, with account and privacy checks at main-loop dispatch and publication, and remove the redundant bridge.

Improve ChatService history readability

2026-08-13T17:54:17Z

Add phase-oriented comments around history synchronization, archive validation, asynchronous view updates, and transcript deletion. Expand dense control flow and restore readable spacing throughout the ChatService implementation and its integration points without changing behavior. Restore unrelated end-of-file formatting so it drops out of the overall PR diff.

Implement ChatService persistent history stitching

2026-08-13T16:17:40Z

Synchronize eligible direct IM conversations through the ChatService capabilities into durable per-resident CSV archives. Validate deterministic conversation IDs, UUIDv1 ordering, complete discovery and history payloads, and the account-wide deletion cutoff before a bounded pass can append or rebuild an archive. Run discovery, pacing, retries, metadata resolution, and participant paging through one account-scoped manager. Immediately prioritize new Direct sessions, P2P previews, and accepted inbound IMs while honoring transcript consent, authoritative mute state, capability changes, and fail-closed account state. Stitch ordinary and monthly legacy plaintext before the oldest accumulated service row, keep normal plaintext logging active, and merge the first validated service page in memory while older backfill continues. Drive Direct and Preview reloads and their nonmodal loading status from shared resident snapshots. Maintain the human-readable chat_service_index.csv manifest and protect archive updates with strict validation, torn-tail repair, corrupt-file preservation, private file stamps, and atomic replacement. Extend Delete Transcripts with a durable TimeUUID boundary and an asynchronous sweep that suppresses every historical source until cleanup completes safely. Add core coverage for deterministic IDs, UUIDv1 and timestamp validation, strict page and list contracts, RFC 4180 CSV quoting, archive scanning, torn tails, and corrupt records.
