Pauses auto-expire (default 5 minutes, capped at 24 hours), an + unused allow-once expires after 10 minutes, and every status surface shows a + loud `⏸ PAUSED` warning with a countdown for the whole window. Block messages + now point at these toggles; the previous advice (an environment variable plus + a tool restart) never reached a backgrounded daemon and has been removed. + +### Fixed +- **A secret-shaped token in conversation history no longer blocks the session.** + Security data checks (credentials, cards, SSNs) now run only inside tool-call + arguments — the agent *action* — never on prose or resent conversation history. + Clients resend the full conversation every turn, so a key-shaped string merely + *quoted or discussed* (e.g. an example key in a summary) used to 403 every + request until the session was abandoned. The exfiltration vector that matters — + a credential leaving the machine inside a tool call — stays fully covered. +- **Subscribers no longer see a notional dollar figure where a plan reading + belongs.** When the latest plan reading is stale (idle, or the proxy was briefly + down), the status line keeps showing last-known plan headroom — marked stale — + instead of falling back to a session-cost figure that reads as real money. The + `status` command frames a subscriber's spend as notional, not a budget breach. + +### Changed +- **Blocks now explain themselves.** A security block names the tool that tripped + it, shows a masked, recognisable preview of what matched (e.g. `AKIA…LKEY`) for + credential/PII hits — the raw value is never echoed or logged — and states why + that class is blocked, instead of a bare category label. +- **A down proxy now looks down.** When routing points at a dead proxy, status + surfaces drop the cost, plan, today, and block-count segments (all stale with no + capture happening) and show only the loud "proxy down" warning alongside the + tool-reported token and context gauges. + ## [0.9.14] — 2026-06-10 A real-world robustness pass driven by dogfooding: a multi-agent review of diff --git a/Cargo.lock b/Cargo.lock index 357a38d..9dec4f5 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -171,7 +171,7 @@ checksum = "5d20789868f4b01b2f2caec9f5c4e0213b41e3e5702a50157d699ae31ced2fcb" [[package]] name = "burnwall" -version = "0.9.14" +version = "0.9.15" dependencies = [ "anyhow", "assert_cmd", diff --git a/Cargo.toml b/Cargo.toml index e30b115..966c8fa 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "burnwall" -version = "0.9.14" +version = "0.9.15" edition = "2024" rust-version = "1.87" description = "Local proxy for AI coding tools (Claude Code, Codex CLI, Aider): cache-aware cost tracking, path/command security checks, daily budget enforcement.
