parseSessionFile(fromOffset) still recovers the active service tier from the already-ingested prefix, but now scans only for service_tier_change entries and keeps a single current tier value instead of materializing every prefix entry. This preserves incremental sync memory behavior for large sessions.
Stats sync depends on service_tier_change entries to derive priority premium requests since 69043d307 stopped folding priority-tier into per-message premiumRequests. parseSessionFile(path, fromOffset) initialized currentServiceTier to undefined per call, so an incremental resume past the tier change attributed subsequent priority OpenAI replies with premiumRequests: 0. When fromOffset > 0, parseSessionFile now replays bytes[0..start] purely to seed currentServiceTier from the latest service_tier_change before parsing the unprocessed tail. Bytes are already loaded, so no extra I/O.
- Added message-ID checks in both assistant and user message parsers so entries without valid ids are ignored.
- This filtering prevents legacy, unlinked message records from being treated as parseable assistant or user messages.
- Added `getPriorityPremiumRequests` and used it in OpenAI and OpenAI Codex providers to increment `usage.premiumRequests` when `serviceTier: "priority"` was sent.
- Combined Copilot and priority premium counts in OpenAI completions and responses usage parsing so emitted usage uses the merged premium total.
- Updated stats parsing/backfill to re-read `service_tier_change` entries and UPSERT only `premium_requests`, so historical sessions pick up priority traffic without mutating other metrics.
- Added new frustration and revised behavior metrics across stats types, parser mappings, and UI charts.
- Reworked session sync to fan out parsing across a capped worker pool with SyncOptions progress callbacks.
- Added worker-based parse messaging and throttled TTY progress rendering in the stats sync command.
- Updated behavior scoring to strip structured content, ignore noisy prompts, and fix profanity boundary regressions.
- Expanded user message schema and migrations, then repaired assistant model/provider links during sync backfill.
- Updated worker-import guidance in AGENTS.md and recorded sync-progress/metrics updates in package changelogs.
- Added user-message behavior metric extraction and parsing for yelling/profanity/drama counts.
- Added behavior persistence and aggregate reads by extending syncSessionFile, DB schema, and query APIs.
- Added behavior dashboard support with new shared types, /api/stats/behavior route, and client views.
- Changed cost summary/chart rendering by removing per-chart 14/30/90-day filters and trend card behavior.
- Added tests for computeUserMessageMetrics edge cases like empty text, case, thresholds, and punctuation.
- Moved tailwindcss from devDependencies to dependencies for shared client styling usage.
- Introduced parseSessionEntriesLenient function that skips over malformed JSON lines and continues parsing valid entries. Updated parseSessionFile to use lenient parsing instead of throwing on parse errors. Updated getSessionEntry to use lenient parsing for robustness when reading session files.
Fixes#273
listSessionFiles() only performed a flat readdir, missing subtask JSONL
files nested inside artifact subdirectories. Switch to recursive readdir
to discover .jsonl files at any depth.
Also fix extractFolderFromPath() to derive the project folder via
path.relative from the sessions root instead of regex on basename, which
returned the artifact directory name for nested paths.
