- Added Anthropic prompt-cache refresh scheduling and state management to keep prompts warm across idle sessions.
- Updated pricing models and database stats tracking to calculate and store cost-weighted cache savings.
- Integrated cache savings metrics and efficiency displays into the stats CLI, dashboard routes, and UI components.
- Added support for package renaming, manifest pointer tracking, and installation migration during CLI updates.
- Add comprehensive Nix flake definitions, derivations, modules, and CI workflows.
- Update tests and executables to resolve binaries from PATH rather than absolute paths.
- Ensure byte reproducibility and zeroed timestamps in embedded dashboard archives.
- Add handling for Nix-managed installations in CLI update checks.
- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
- server-port-conflict opened the module-global db against the live agent stats.db, poisoning later files (sync-serial read 2.28M real rows); installStatsTestIsolation gives it a temp agent dir and closes the handle in teardown
Versioned the dashboard identity header and required the current security version with no CORS permission before reusing a listener.
Older versioned and headerless stats dashboards are now identified by their process and restarted so loopback-only binding takes effect immediately.
Fixes#7633
Replaced the 127.0.0.2 fetch, which a configured HTTP proxy could intercept, with a direct Bun.connect TCP probe so the loopback-only bind is asserted against the real listener.
Fixes#7633
Bound the dashboard and reuse probe to IPv4 loopback, removed wildcard CORS, and reported the actual listening hostname.
Added regression coverage for non-loopback refusal and absent cross-origin access.
Fixes#7633
- Added native `FileLock` bindings supporting cross-process advisory locking on Linux, Unix, and Windows.
- Replaced directory-based file locking and custom stale-lock reclamation with OS-backed native locks.
- Updated TypeScript declarations, native bindings, and package documentation for the new API.
- Added comprehensive unit tests and fixtures validating single-owner constraints and process death handoff.
- Moved the coding-agent lock-directory primitive to @oh-my-pi/pi-utils/file-lock
and migrated settings, MCP config-writer, and security store imports.
- Replaced the stats aggregator's parallel ~200-line token/breaker lock protocol
with the shared primitive: dead owners reclaimed immediately, live-but-wedged
owners after STATS_SYNC_LOCK_STALE_MS, unstamped acquisitions after the new
acquireStaleMs grace (10s).
- Shared primitive now treats EPERM kill probes as live owners.
- Rewrote the stats lock-reclamation regressions against the shared protocol
and moved the file-lock contract test into pi-utils.
Installed a five-second SQLite busy timeout before the read-only usage query and covered lock contention with a subprocess-backed regression test.
Fixes#7300
- Add usage history, reporting, and client summary endpoints to the auth broker.
- Implement SQLite persistence, batching, and periodic flushing for observed client usage.
- Integrate usage reporting into the coding agent session for completed assistant messages.
- Update stats aggregator and dashboard to retrieve usage history snapshots from the broker.
