- Implemented mutable session titles with audit tracking, including storage persistence for SQL and Redis backends.
- Added comprehensive session management features such as idle recap triggers, incremental subagent yield submissions, and automated title refreshing.
- Enhanced task tracking in the TodoTool with progress prioritization and improved session cleanup logic.
- Introduced citation tag handling for OpenAI-compatible source markers and improved edit parsing.
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
- Added `IndexedSessionStorage` with `SessionStorageBackend` for index-based storage reads.
- Removed `readTextSync` from the public `SessionStorage` API and sync backends.
- Changed Redis and SQL backends to warm `{size, mtimeMs}` metadata and read via `readTextSlices`.
- Added per-path write queues and `drain()` to serialize operations and surface first failures.
- Classified each session's final message as done, interrupted, aborted, error, or pending from a 32 KiB tail read.
- Rendered the status as a colored segment on the session metadata line.
- Added `peekFileTail` and `readTextSuffix` across storage backends to read file tails in one pass.
- Simplified `MemorySessionStorage` to a string array mirror with a sidecar mtime map.
F6: defer the JSON -> YAML migration out of ConfigFile's constructor and
add an async path so the boot sequence stops blocking the event loop on
sync I/O. New ConfigFile.tryLoadAsync/loadAsync/loadOrDefaultAsync/
getMtimeMsAsync and static ConfigFile.warmup. The migration is now
idempotent (per-process cache) so relocate() does not re-run it.
ModelRegistry.create(authStorage, modelsPath?) is a new async factory
that runs the warmup before the sync constructor's bundled-model load.
Production call sites (main.ts, sdk.ts, task/executor.ts, commit
pipelines, SDK example) all switched. Sync new ModelRegistry(...)
constructor is still supported for tests.
F2: rewrite MemorySessionStorage's mirror as { chunks: string[]; byteLen;
mtimeMs } so writeLineSync appends a single chunk in O(1) instead of
read-modify-writing the entire file (which was O(N) per append, O(N^2)
per session). statSync now reports true UTF-8 byte length instead of
character count. readTextPrefix walks chunks until the byte budget is
exhausted instead of materialising the full mirror.
Also rolls in per-package CHANGELOG entries for F1-F8.
