Command-shaped rules (denied paths/commands, network mounts, + destructive commands, exfil techniques) now apply only inside tool-call + argument subtrees (Anthropic `tool_use.input`, OpenAI + `tool_calls`/`function_call` arguments, Gemini `functionCall`) — the places + an agent actually acts. Secret detection and DLP still scan the entire + payload, and MCP `tools/call` bodies keep the strict whole-body scan. +- **A blocked tool call no longer poisons the conversation forever.** Clients + resend the full history on every request, so one (correctly) blocked call + used to re-trigger the 403 on every subsequent message — the only escapes + were a new conversation or the bypass switch. Command-shaped rules now apply + to the **latest assistant turn's in-flight tool round** only: the request + carrying the dangerous call (and its results) is still blocked, but once the + user sends a new message that round is adjudicated history and the + conversation continues. Secrets/DLP still scan all turns, so sensitive + content in old results stays caught. +- **`burnwall stop` no longer strands routed shells on a dead proxy.** Stopping + the proxy used to leave `ANTHROPIC_BASE_URL`/`OPENAI_BASE_URL` pointing at + the closed port, so every AI tool failed with a connection error until the + user discovered `disable-routing`. `stop` now pauses routing (new shells go + direct), prints how to clear the variables from already-open terminals, and + `start` resumes routing automatically. An explicit `burnwall + disable-routing` is remembered and never overridden by `start`; opt out of + the coupling with `stop --keep-routing` / `start --no-routing`. + +### Added + +- **`uninstall` now removes routing env files instead of stubbing them, and + warns about already-open terminals.** The leftover banner-only stub was + residue on a machine the user asked to clean, and it kept counting the + shell as "configured" forever (fish/PowerShell are detected by env-file + presence). Uninstall also can't pull env vars out of running shells — no + uninstaller can — so it now says so and prints the per-shell unset command. + +- **Pricing for Claude Fable 5 and Opus 4.8** (both released 2026-06-09): + `claude-fable-5` at $10/$50 per MTok (cache write $12.50, read $1.00) and + `claude-opus-4-8` at the standard Opus $5/$25. Pricing lookup now also + resolves bracket variant tags — Claude Code requests the 1M-context tier as + `claude-fable-5[1m]`, which previously fell through to "unknown model". + +## [0.9.12] — 2026-06-09 + +### Fixed + +- **Routing commands now act on every configured shell, not just the detected + one.** A user often drives more than one shell (on Windows, PowerShell *and* + Git-bash are the norm). Previously `enable-routing` / `disable-routing` / + `uninstall` resolved a single shell and touched only its env file + rc hook, so + enabling from PowerShell left bash silently unrouted (and `uninstall` could + leave a live rc hook pointing at a removed proxy). They now sync the detected + shell **plus** every shell already configured for routing, keeping them + consistent. Bash/zsh are disambiguated by their rc-hook (they share one + `env.sh`); fish/PowerShell by their own env files — so a never-used shell is + never pulled in (no spurious `~/.zshrc`). + +### Added + +- **Not-routed warning on the Claude Code status line.** When a tool's traffic + isn't flowing through the proxy, the ribbon shows a loud `⚠ DIRECT + (unprotected)` chip (and `⚠ bypass` when `BURNWALL_BYPASS` is set) right after + the model — so "the proxy is running but my traffic isn't reaching it" can't go + unnoticed. Detected from the tool's `*_BASE_URL` in the environment the status + line inherits; silent on the healthy path. +- **Routing readout in `burnwall status`.** A per-shell line states whether this + shell points traffic at the proxy, with the one-line fix when it doesn't; also + surfaced as `env_routing` in `status --json` for the editor extension. +- **Colorized console output.** The install scripts (`install.sh` / `install.ps1`), + the proxy banner, the background-start and login-service messages, and the + routing/coverage readouts now use semantic color (green = active/healthy, + yellow = caution, red = unprotected). Honors `NO_COLOR` and non-TTY output, so + piped/redirected text stays clean. + +## [0.9.11] — 2026-06-08 + +### Added + +- **Subscription-aware status, across every surface.** For a Claude Pro/Max plan, + dollar figures are notional (you pay a flat rate), so Burnwall now shows what's + actually scarce: your usage-window headroom. The proxy reads Anthropic's + `anthropic-ratelimit-unified-*` response headers (rolling 5-hour + 7-day windows) + off traffic it already forwards and persists a small, non-sensitive, **per-provider** + snapshot; surfaces render e.g. `5h [▓░░░░░░░] 17% (1h56m) · 7d 10%` in place of the + dollar segment, leading with whichever window the provider reports as binding and + flagging a throttled status. Auto-detected (a subscription emits these headers, an + API key doesn't — verified against Anthropic's docs), so API users keep the + dollar/cost view with no configuration; falls back to dollars when no fresh snapshot + exists. Surfaced on: + - the **Claude Code status line** (`burnwall statusline`); + - **`burnwall watch`** — the cross-tool pane for CLIs without their own status bar + (Codex, Aider, …): run it in a split pane to see the gauge; + - **`burnwall watch --title`** — emits the ribbon as a terminal-title (OSC) escape, + for a shell prompt hook or `tmux status-right`, so even a status-bar-less CLI gets + it in the window title; + - **`status --json`** — a `plan` block (per-provider windows + reset countdown), + rendered by the **VS Code / Cursor / Windsurf extension** status bar + tooltip. + + The capture is provider-generic; OpenAI/Google hooks exist but return nothing until + their subscription signal is probed and verified (we don't synthesize a window from + per-minute API limits). + +- **Coverage readout — which of your tools are actually behind the firewall.** A + proxy only protects traffic that flows through it, and the dangerous failure mode + is *silent* non-coverage — a tool you assume is protected whose traffic never + reaches Burnwall. Burnwall now makes coverage visible per installed tool: + - **`burnwall init`** warns at setup when a detected tool is in a bypassing mode — + concretely, Codex signed in with ChatGPT login (read from `~/.codex/auth.json`, + a local non-secret mode flag), whose traffic goes to the ChatGPT backend over + OAuth and can't be routed through any no-MITM proxy. It notes that API-key + mode would route through Burnwall but bills per-token — an informed trade-off, + not a blanket "switch." + - **`burnwall status`** and **`burnwall watch`** show a per-tool **Coverage** + section: *protected* (provider seen routing recently), *installed but no traffic + seen*, or *bypasses*. `status --json` carries a `coverage` array, and the VS Code + / Cursor / Windsurf extension surfaces a `⚠ unprotected` warning plus a + tooltip breakdown. + - README documents the boundary outright. + +- **More official security rule packs.** The bundled, signed-release rule packs + grew from 4 to **8** — added `node`, `python`, `go`, and `kubernetes`, and + fleshed out `django` / `react` / `infrastructure` / `data-science` (now ~61 + rules total). Each targets unambiguously sensitive credential/state files + (`.npmrc`, `.pypirc`, kubeconfigs, `terraform.tfstate`, …) and genuinely + destructive commands, keeping the low-false-positive bar. Install with + `burnwall rules install `; list with `burnwall rules list`. +- **`burnwall rules lint`** — validate a rule pack against strict acceptance rules + (stricter than the runtime: forbidden/unknown keys, uncompilable or over-broad + rules are hard errors), optionally verifying its signature (`--sig`). Exits + non-zero on any error and supports `--json`, so it can gate a community rule + repo's CI. The bundled official packs are themselves checked by it in CI. + +### Changed + +- Status ribbon now carries a `burnwall` wordmark — `🔥 burnwall · · …` — + across every surface (Claude Code status line, `burnwall watch`, editor status + bar), which share one renderer. +- `short_model` now keeps a trailing context-variant tag and upper-cases it, and + no longer lets it defeat the version dotting: `claude-opus-4-8[1m]` renders as + `opus-4.8[1M]` (was `opus-4-8[1m]`). + +## [0.9.10] — 2026-06-08 + +### Added + +- **`burnwall init` now wires up the Claude Code status line.** When Claude Code + is detected, `init --apply` merges a `statusLine` block into + `~/.claude/settings.json` so the Burnwall ribbon (model · ↑/↓ tokens · spend) + appears automatically — no hand-editing JSON. The merge is idempotent, + preserves your other settings, writes the PATH-resolved `burnwall statusline` + command, and never overwrites a status line you already configured. +- **`burnwall uninstall`** — one command to undo everything `install` + `init` + set up: stops the proxy, removes the login service, removes the Claude Code + status line (a foreign one is left untouched), empties the routing env file and + removes the rc-source hook, and removes the binary. Your cost-history database + is kept by default; `--purge` deletes the whole `~/.burnwall` data directory. + Confirms before acting (skip with `--yes`); refuses to run non-interactively + without `--yes`. + +### Changed + +- `burnwall upgrade` now sweeps the leftover `burnwall.exe.old` from a previous + Windows self-upgrade on the next launch, so the transient renamed binary never + lingers (best-effort, silent; the running binary can't delete itself). + +## [0.9.9] — 2026-06-08 + +### Added + +- **`burnwall upgrade`** (alias `self-upgrade`) — one command to move to the + latest release. It stops the running proxy first (a live `burnwall.exe` can't + be overwritten on Windows), runs the installer, and restarts the proxy. On + Windows it renames its own running binary aside so the installer can write the + new one, restoring it if the install fails. `--dry-run` to preview, + `--no-restart` to skip the restart. The mirror of `self-rollback`. + +## [0.9.8] — 2026-06-07 + +### Added + +- **`burnwall savings`** — your own *measured* cache-savings report: dollars + recovered through caching over a window (from real token buckets at published + cache-read vs base-input rates), plus models that are underusing caching. No + marketing percentages — your numbers. +- **`burnwall watch` / `status` self-test heartbeat** — `status` now states + plainly whether protection is live ("proxy running (pid …); every request is + scanned"), so a passive proxy never leaves you wondering if it's working. +- **`burnwall share`** — an opt-in, screenshot-friendly, **signed** value card + (spend / cache savings / blocks), verifiable against the local audit key so the + numbers can't be faked. Nothing leaves your machine. +- **`burnwall sidecar`** — run the proxy as a co-located egress point for an + agent that executes off your laptop (self-hosted sandbox / container / CI + runner), with the in-sandbox env-var recipe. Same scanning + budgets; not a + TLS-terminating proxy (no CA injection — see `SECURITY.md`). +- **Catastrophic-command detection by shape** — recursive-force deletes, disk + destruction (`dd of=/dev/…`, `mkfs`), and destructive SQL (`DROP`/`TRUNCATE`) + are blocked regardless of flag order, spacing, or target expansion — the forms + that slipped past literal/approval checks in real incidents. +- **Data-exfiltration technique detection** (opt-in under `security.dlp`): DNS + exfiltration, secret-file-piped-to-network, command-substituted uploads. +- **Per-session / swarm budget ceiling** (`budget.per_session`, opt-in via an + `x-burnwall-session` request header) — agents in a fan-out that share a session + id share one blast-radius cap; `status` shows a per-session breakdown. +- **Build provenance** — releases now carry GitHub Artifact Attestations (SLSA + Build L2); verify with `gh attestation verify … --repo intbot/burnwall`. New + `SECURITY.md` documents integrity + TLS handling (rustls, no CA injection, no + plaintext at rest), backed by a guard test. + +### Changed + +- `command_matches` is whitespace-normalized, so padding (`rm -rf /`) can't + evade a literal deny rule. +- README: "Verify your download" + the trust/defense-in-depth sections. + +## [0.9.7] — 2026-06-07 + +### Added + +- **Data-exfiltration technique detection** (opt-in, under `security.dlp`) — the + scanner now flags the exfiltration *method* in a tool-call argument, not just + secrets in the payload: DNS exfiltration (`dig $(...).evil.com`, encoded + subdomains), a secret file piped to the network (`cat .env | curl -d @-`), and + command-substituted uploads. Conservative/high-signal (a network tool alone is + fine) and names only the technique, never the data. +- **`burnwall security --summary`** — a "what Burnwall caught for you" receipt: + blocks grouped by type over the window (pairs with `--days 7`), so passive + protection registers as ongoing value instead of going unseen. +- **`burnwall audit pack`** — one-command compliance evidence pack: bundles the + signed hash-chained receipts, the CycloneDX 1.6 AIBOM, and the SARIF 2.1.0 + security findings into a directory with a `MANIFEST.md` that maps each artifact + to the controls auditors ask for (ISO/IEC 42001, EU AI Act Art. 12/26, FINRA). + The artifacts already existed; this is one command + the framework mapping you + can hand a security team. +- **MCP firewall is validated against the published attacks** — a test corpus + models the real PoCs (Invariant tool-poisoning / SSH-key exfiltration, the + MCPoison rug-pull that swaps a tool's behavior after approval, `` + shadowing) so coverage is provable and stays covered. + +### Changed + +- README: a **Trust & privacy** section (local, zero-telemetry, read-only on + responses, signed single-binary releases, auditable "no network except + forwarding"), a **defense-in-depth** framing for security (rules run before + anything leaves your machine; complements — doesn't replace — native + controls), and the MCP scope note now points at the built-in `mcp-watch` + firewall (tool-poisoning + rug-pull detection). + +## [0.9.6] — 2026-06-07 + +### Added + +- **`burnwall watch`** — a live, cross-tool status ribbon for a spare terminal + pane. The in-TUI ribbon only works in Claude Code; this shows the *same* + renderer for every tool that routes through the proxy (Codex, Gemini, Aider, + …), sourced from the local database. `--oneline` for a compact line, `--once` + for a single frame (scripting/tests), `--interval` for the fallback refresh. + It refreshes event-driven off the `watch.signal` marker the proxy touches each + turn, with a periodic fallback. The headline figure is **today's spend across + all tools** — the cross-tool number no single tool shows. +- The status ribbon's context gauge stays honest on this surface: no tool feeds + an exact context %, so it's an estimate (`~`) when the model's window is known + and the prompt fits, and `—` otherwise — never an unqualified number. + +### Changed + +- Ribbon cost fields (`sess`, `today`) are now rendered only when known, so the + cross-tool view (which has no per-session concept) shows per-message + today + without a misleading "session" figure. + +## [0.9.5] — 2026-06-07 + +### Added + +- **`burnwall statusline`** — renders the Burnwall ribbon for Claude Code's + customizable status line. Reads Claude Code's per-turn JSON on stdin and prints + one line: `🔥 sonnet-4.6 · ↑13k ↓615 · $0.05 msg $0.16 sess · $2.40 today · ctx + [▓▓░░░░░░] 22%`. Per-message cost is derived from the cumulative session total; + today's spend and security-block count are enriched from the proxy database, so + the line reflects spend **across all your tools**, not just the current one. + Wire it up with one line in `~/.claude/settings.json`: + `{ "statusLine": { "type": "command", "command": "burnwall statusline" } }`. + Fail-open: malformed input or an unreadable database still yields a best-effort + line rather than breaking the editor. +- **Context gauge is honest by construction** — the ribbon shows a context-window + percentage only when it's *exact* (reported by the tool, e.g. Claude Code). + Where a value is estimated it's flagged with `~`; where the window can't be + trusted it renders `—`; where the tool already shows its own gauge it's omitted + rather than duplicated. +- **Activity marker** — the proxy touches `/watch.signal` after each + recorded turn (off the response path, so no added latency), laying the + groundwork for event-driven refresh of upcoming status surfaces. + +### Fixed + +- **`burnwall install-service` on Windows no longer needs admin.** It previously + created a Scheduled Task at the Task Scheduler library root, which requires + elevation and failed with "Access is denied" for a normal shell. The default is + now a per-user `HKCU\…\Run` registry entry that launches `burnwall start + --daemon` at logon — no UAC. `--task` opts back into the Scheduled-Task variant + (which adds crash-restart) for users who run an elevated terminal. + `uninstall-service` removes whichever was installed. + +## [0.9.4] — 2026-06-07 + +### Added + +- **Five-layer graceful-degradation model**, so a bad release can't break your AI + tools: + - `BURNWALL_BYPASS=1` — instant kill-switch. Proxy becomes a pure relay; no + security scan, no budget check, no storage write. Forward bytes to the + upstream and stream the response back unchanged. + - **Panic-catching wrapper** — if anything in the request pipeline panics, the + proxy returns a clear 502 (pointing the user at `BURNWALL_BYPASS=1`) instead + of dropping the connection. + - **Crash-loop circuit breakers** baked into each platform's service unit + (launchd `ThrottleInterval=60`, systemd `StartLimitBurst=5`, Task Scheduler + `RestartOnFailure` capped at 5 attempts). + - **`burnwall self-rollback `** — fetches the version-pinned dist + installer for any prior release and reinstalls. Windows refuses to roll back + while the proxy is running so it can replace the binary safely. + - **Sourced env-file activation model** — one burnwall-owned file + (`~/.config/burnwall/env.sh` / `%APPDATA%\burnwall\env.ps1`) holds the + routing exports; the user's rc gets one idempotent source line. Disable by + truncating the env file — one place to revert. +- **`burnwall enable-routing` / `disable-routing`** — write/clear the env file, + install the rc-hook, and emit eval-able exports for immediate-effect + activation in the current shell (`eval "$(burnwall enable-routing)"` on POSIX, + `burnwall enable-routing --eval | Out-String | Invoke-Expression` on + PowerShell). `enable-routing` runs a `/healthz` preflight against the proxy + before activating. +- **`burnwall install-service` / `uninstall-service`** — registers burnwall as a + login-time service so the proxy auto-starts. User-scoped (no admin needed) on + all three platforms: launchd LaunchAgent on macOS, systemd user unit on Linux, + Windows Scheduled Task at logon. +- **`/healthz`** local probe — returns 200 without touching upstreams. Used by + the activation preflight, the supervisor circuit breaker, and any external + monitor. +- **Extended `burnwall init`** — two-step interactive flow that now also offers + login-service install and routing activation in the same run. `--apply` to + execute, `--yes` for unattended scripted use, `--install-service` to opt in to + the supervisor. +- **Local pricing overrides** — drop a `~/.burnwall/pricing.toml` to override or + add model rates without waiting for a release. Entries take precedence over the + built-in rate card and handle date-suffixed model IDs automatically, so a + brand-new model can be priced immediately and a mid-cycle price change is a + two-line edit. This is the escape hatch the staleness warning always + advertised — now actually wired up. +- **`burnwall pricing` command** — `list` shows the effective rate card (built-in + plus overrides, with the source of each), `path [--init]` prints/scaffolds the + override file. +- **Signed remote pricing cards** — `burnwall pricing update` fetches a + `pricing.toml` from a URL (default: the latest GitHub release asset) and + installs it **only** if its detached Ed25519 signature verifies against a + trusted `[pricing].publishers` key — verify-before-parse, no fail-open. + `pricing sign` / `pricing verify` cover the publisher and offline-check sides, + reusing the same key format as `burnwall rules keygen`. Lets prices ship + between binary releases without giving up zero-trust. + +### Changed + +- **`burnwall init` output reworked** — dry-run output now lists the two actions + (routing + service) with the exact file paths and exports that would be + written.

SECURITY CHECK (request body): - a. Parse JSON body - b. Scan for tool_use / function_call blocks - c. For each tool call: - - Check file paths against deny_paths list - - Check commands against deny_commands list - - Check for network mount paths (/Volumes/, \\, smb://, nfs://) - - Check for secret patterns (AWS keys, API tokens, private keys) - d. If ANY rule matches: - - Return HTTP 403 with JSON error body: - {"error": {"type": "security_blocked", "message": "Burnwall blocked: attempted read of ~/.ssh/id_rsa"}} - - Log blocked event to SQLite - - Print warning to terminal: 🛡️ BLOCKED: ... - - Do NOT forward the request -4.

Rewrite URL: strip /anthropic, /openai, or /google prefix - b. Forward all headers unchanged (including auth) - c. Forward body unchanged - d.

PARSE response usage block: - a. Extract token counts by type (input, cached, output, cache_write) - b. Look up model in pricing database - c. Calculate real cost with cache-aware pricing -7. LOOP DETECTION [v0.2]: - a. Hash first 200 chars of request content - b. Check if same hash appeared N+ times in last M seconds - c. If loop detected: block with 429, exponential backoff -8.

[`install`]; `uninstall` calls [`remove`]. +//! +//! ## Principles +//! +//! - **Idempotent merge.** We parse the existing settings, set *only* the +//! `statusLine` key, and write everything else back untouched. Re-running is +//! a no-op. +//! - **Never clobber a foreign status line.** If the user already points +//! `statusLine` at something that isn't ours, we leave it alone and report +//! it — security software doesn't silently overwrite your config. +//! - **PATH-resolved command.** We write `"burnwall statusline"`, not an +//! absolute path, so the wiring survives a reinstall to a different dir +//! (the installer puts `burnwall` on PATH). + +use std::path::{Path, PathBuf}; + +use anyhow::{Context, Result}; + +/// The command we write into `statusLine.command`.
