Changelog

[Unreleased]

Fixed

• Fixed a SQLITE_CONSTRAINT_NOTNULL crash (messages.stop_reason) aborting the entire session sync when a persisted assistant message lacks a stopReason. Malformed entries — missing stop reason, token counts, or message timestamp — are now coerced at the parser boundary, and entries with no usage or model attribution are skipped instead of failing the batch insert.

[16.4.2] - 2026-07-10

Fixed

• Fixed a crash during stats synchronization on legacy session entries that lack a cost breakdown by falling back to catalog pricing when available.

[16.3.9] - 2026-07-06

Changed

• Refined behavior metrics to significantly reduce false positives in profanity, yelling, and anguish detection by excluding technical terms (e.g., "dummy", "trash", "garbage"), neutral punctuation (e.g., dot runs), and single-word capitalization (e.g., filenames or environment variables).
• Re-categorized frustration interjections (such as "ugh", "argh", and "grr") from profanity to anguish.
• Improved negation and blame detection to exclude determiners (e.g., "no auto start") and compounds (e.g., "no-op") while adding support for phrases like "why did you" and "makes no sense".
• Added sad emoticons as a signal for anguish while excluding code-like patterns.
• Triggered a one-time automatic re-ingestion of sessions on the next database sync to apply the updated metrics.

[16.3.7] - 2026-07-05

Changed

• Optimized session-entry lookup and file reading performance by caching file metadata to avoid repeated full-file scans.

[16.3.1] - 2026-07-02

Added

• Added a Tools tab to the omp stats dashboard (/#/tools): per-tool call counts, error rates, result/argument payload sizes, per-model breakdown, and a stacked calls-over-time chart. Token and cost columns attribute each invoking turn's real provider usage evenly across that turn's tool calls. Existing databases re-parse sessions once on the next sync to backfill historical tool calls.

[16.2.7] - 2026-06-30

Fixed

• Improved premium request calculation accuracy by correctly accounting for specific model families.

[16.2.6] - 2026-06-29

Fixed

• Fixed application crashes and Bun aborts on macOS and when parsing large stats session files, including during omp --smoke-test runs, by utilizing a more resilient serial parser and lenient line scanner.

[16.2.3] - 2026-06-28

Added

• Support for parsing named advisor transcripts using the __advisor.<slug>.jsonl naming convention.

[16.2.0] - 2026-06-27

Added

• Added a Gain tab to the omp stats dashboard (/#/gain) to display snapcompact token-savings with project scoping from synced session folders.

[16.1.17] - 2026-06-24

Fixed

• Stats sync counted the same provider request multiple times when a forked or branched session file copied the parent's entries verbatim. Inserts now skip rows whose (entry_id, timestamp) already exists under a different session_file, and a one-shot migration on the next omp stats run collapses any pre-existing duplicates (#3370).

[16.1.15] - 2026-06-22

Added

• Added token usage breakdown by agent type (Main, Subagents, Advisor) to the overview dashboard

[16.0.10] - 2026-06-18

Changed

• Updated description of moderated content categories to use more inclusive terminology

Fixed

• Wide data tables (Requests, Errors, Overview, Projects) overflowed the page horizontally at narrow-desktop widths (768-1023px): the .stats-table-desktop-only wrapper used for mobile-card tables lacked the overflow-x: auto containment that .stats-table-container already has. They now scroll within their own bounds instead of spilling the page body.

[16.0.5] - 2026-06-17

Added

• New Projects view summarizing usage, cost, and reliability per project folder (backed by the existing /api/stats/folders endpoint).
• System-aware light/dark theme toggle — follows the OS by default, and an explicit choice persists across reloads.

Changed

• Redesigned the local stats dashboard with an OMP-themed product shell, dedicated per-section views, accessible loading/empty/error states, and flicker-free navigation between screens and time ranges.

Fixed

• The 1h time-range chart rendered an empty/single-point line; it now buckets at 5-minute granularity for a real trend.

[15.13.3] - 2026-06-15

Changed

• Renamed __omp_stats_sync_worker to __omp_worker_stats_sync.

[15.13.1] - 2026-06-15

Fixed

• Dropped git from the profanity list so normal repository mentions no longer count as profanity

[15.12.4] - 2026-06-13

Fixed

• Fixed the stats dashboard's SQLite init never setting PRAGMA busy_timeout, so a concurrent omp startup hitting WAL recovery could crash initDb() with SQLITE_BUSY instead of waiting through it. The busy handler is now installed before PRAGMA journal_mode=WAL (#2421).

[15.11.0] - 2026-06-10

Added

• Added support for prebuilt npm bundle mode via PI_BUNDLED, allowing the stats server to use an embedded dashboard bundle in packaged CLI distributions

Fixed

• Fixed handling of legacy embedded-client.generated.txt placeholder content so it is treated as missing archive instead of being decoded into invalid bytes
• Fixed ENOENT handling while scanning dashboard source/build directories so missing client/ or dist/client trees no longer crash startup

[15.10.11] - 2026-06-10

Changed

• Bundled-model lookups (getBundledModel, GeneratedProvider) now import from the new @oh-my-pi/pi-catalog package instead of the @oh-my-pi/pi-ai barrel, which no longer re-exports catalog values
• The session-sync worker re-enters the host CLI entry (workerHostEntry() + __omp_stats_sync_worker argv selector) when running inside omp — source, npm bundle, or compiled binary — and keeps loading its own sync-worker.ts module directly for standalone omp-stats, bun test, and SDK hosts

[15.1.6] - 2026-05-19

Fixed

• Fixed omp stats crashing on first session sync in published omp-{linux,darwin,windows}-* binaries with BuildMessage: ModuleNotFound resolving "./packages/stats/src/sync-worker.ts"; the release build script now lists the stats sync, browser tab, and JS eval workers as explicit --compile entrypoints so Bun emits them into bunfs, matching the dev build script and the AGENTS.md worker spawn contract. (#1150)

[15.1.0] - 2026-05-15

Fixed

• Fixed incremental parseSessionFile(path, fromOffset) losing the active service tier when resuming past a service_tier_change entry, so priority OpenAI replies appended after the offset are now credited with premiumRequests: 1 (regression introduced by 13f59162e which stopped folding priority-tier into per-message premium counts)

[15.0.1] - 2026-05-14

Breaking Changes

• Raised the minimum required Bun version to >=1.3.14 in package metadata

Changed

• Changed the "Premium Reqs" dashboard card to also include OpenAI priority service-tier requests (serviceTier: "priority"), counting each as 1 premium request alongside GitHub Copilot premium calls. Pre-existing sessions are backfilled on the next omp stats run: a one-shot premium_requests_priority_v1 sentinel wipes file_offsets so every session re-parses, and insertMessageStats now UPSERTs premium_requests (other columns untouched) using the service_tier_change entries already in the session log to retroactively credit priority traffic.

[14.9.9] - 2026-05-12

Added

• Added separate input-token and output-token totals to the overview dashboard cards.

Fixed

• Fixed omp stats in compiled binaries by using the serial sync path instead of spawning a raw file-asset worker that cannot import bundled parser code.
• Fixed behavior backfills after failed compiled-binary sync attempts by marking the backfill sentinel only after a successful full sync.

[14.9.7] - 2026-05-12

Breaking Changes

• Broke backward compatibility of behavior stats fields by replacing yellingSentences/dramaRuns with yelling/anguish and adding negation, repetition, blame in query result types and persisted user_messages schema

Added

• Added SyncOptions to syncAllSessions with onProgress and workers to optionally show per-file sync progress and tune parser concurrency
• Added new frustration behavior metrics (negation, repetition, blame) plus a frustration aggregate in behavior charts, model tables, and summary cards

Changed

• Changed sync ingestion to parse session files through a worker pool while applying parsed results and database writes on the main thread
• Changed behavior analysis to strip code blocks, XML/URLs, quoted lines, and placeholders before scoring and to suppress signals on long structured messages
• Changed dashboard metrics labels and totals to the new signal names, including replacing the old three-signal totals with yelling, profanity, anguish, and frustration
• Changed sync output to print a live terminal progress indicator while processing session files

Fixed

• Fixed user-message attribution so assistant model/provider links are backfilled during incremental sync instead of being left unknown
• Fixed word-boundary regex handling in profanity detection so matching now works as intended in normal prose

[14.9.5] - 2026-05-12

Added

• Added time range selection options (1h, 24h, 7d, 30d, 90d, All) to the dashboard header and bound them to reloading statistics for the selected window
• Added a Behavior dashboard page that tracks user yelling (CAPS), profanity, and dramatic punctuation (!!! / ???) per day, with by-model comparisons mirroring the cost page
• Added a per-model behavior table to the Behavior page mirroring the Models table: sortable rows of CAPS / profanity / drama hits per model with sparkline trend and an expandable per-model breakdown chart
• Added optional range query parameter support on stats endpoints to retrieve metrics scoped to a requested time window

Changed

• Changed the Costs dashboard summary to report totals, average per day, and top model for the selected time range instead of a fixed 30-day window and removed the previous-30-day trend comparison
• Changed behavior metrics ingestion to compute yelling from user message sentence-level uppercase ratios, filtering out short uppercase fragments so the behavior data is attributed to messages more accurately
• Removed per-chart 14/30/90 day pickers on Costs and Behavior pages so every page obeys the single time-range selector in the header
• Changed dashboard and stats queries to return data from the selected time window instead of always using all-time aggregates
• Changed the default displayed range in the UI/API to last 24h
• Added support for returning all data when range=all is requested

Fixed

• Fixed handling of unknown range values by falling back to the last 24h instead of returning unscoped data
• Fixed omp stats failing to build the client on globally-installed installs by promoting tailwindcss from devDependencies to dependencies (the client build runs at runtime)

[14.5.4] - 2026-04-28

Fixed

• Fixed GPT cost reporting by deriving missing OpenAI Codex costs from the model catalog and backfilling existing zero-cost rows.

[13.6.0] - 2026-03-03

Fixed

• Include subtask session files in usage stats (#250)
