v0.1.0

[0.1.0] - 2026-08-16

• Initial release: aggregated token/cost metering, budget caps with threshold alerts and over-limit policies, carbon footprint estimation, per-model latency benchmarks, and the /budget command.

Added

• Aggregated token/cost metering per model, session, and day from the session/event stream (assistant/message usage with request/header provider/model attribution), priced through the built-in USD-per-1M table merged with config.prices.
• Session/daily/monthly budget caps with warn-ratio threshold alerts (webhook POST + desktop-notification flag) and alert/block/degrade over-limit policies; block/degrade short-circuit the llm/stream waterfall with a corrective error finish (loop-built requests are frozen and cannot be rewritten, so degrade names the target model instead).
• Carbon footprint estimation via the token→carbon bridge (tokens × kWh/token × PUE × regional intensity).
• Per-model latency statistics with p50/p95 aggregation over a bounded window.
• budget Typert Remote namespace (budget/status, budget/setSettings, budget/unblock) + the browser Settings tab (usage bars, model breakdown, alerts, cap editors, unblock).
• /budget command (overview, models, unblock <scope>).
• budget/alert and budget/block session audit events (microtask-deferred past the session-append reentrancy guard).
