feat(egress): change the noise profile at runtime

The egress governor is now a current governor that SetProfile swaps: new requests use the new one, requests in flight finish on the old one, and one package-level ticker logs the counters of the current governor. WebFetch, the http custom tools and the enrich probe resolve it per request, and the agent prompt block reads the current profile. The noise_profile setting (off, quiet, balanced, aggressive) is applied at startup and wins over ARTEX_NOISE_PROFILE, which stays the fallback; PUT /api/settings validates, stores and applies it without rebuilding agents, and GET /api/settings/noise returns the per-host counters without resetting them. System settings gets a Target noise card.

+## [Unreleased]
+
+### Added
+
+- **Noise profile at runtime**: System settings has a **Target noise** card. It sets the profile (`off`, `quiet`, `balanced`, `aggressive`) through the `noise_profile` setting, which takes precedence over `ARTEX_NOISE_PROFILE`. The change applies to the next WebFetch, http custom tool and enrich request, and to the next agent prompt, without a restart. The card also shows the per-host counters, which `GET /api/settings/noise` returns.
+
+### Changed
+
+- **Untrusted-output boundary is now on by default**: Norma frames tool results for the worker, planner, chat and main agent unless `ARTEX_UNTRUSTED_BOUNDARY` is set to `0`, `false`, `off` or `no`. It was opt-in via `ARTEX_UNTRUSTED_BOUNDARY=1` in 0.6.0 (#166).

+
+ARTEX is a self-hosted, LLM-driven penetration testing platform. It is not a chat wrapper around
+a scanner: a planner splits a goal into intents, workers execute them with real tools, and the
+results are written back into **two linked graphs**: one for what you know about the target, one
+for how the test is progressing. Every finding can carry the captured request and response that
+justify it, and every autonomous action passes through scope rules, approval gates and budgets.
+
+- **It explores, it doesn't chat.** Goal decomposition, intent dispatch, worker execution and
+  write-back form a closed loop that keeps advancing until the goal is proven.
+- **Two graphs, one audit trail.** The shared asset graph says *what exists*; the per-task
+  exploration graph says *what was tried, what it produced, and why*. Anchors link the two.
+- **Findings with evidence.** A recording MITM proxy and a browser extension capture real traffic;
+  findings, evidence quotes and retests are tied to the exact request/response.
+- **Autonomy with brakes.** Human-in-the-loop approvals, argv-prefix rules, scope/deny gates,
+  token and turn budgets, a target noise governor, and prompt-injection framing on tool output.
+- **Self-hosted and model-agnostic.** One Go binary with the Next.js UI embedded, PostgreSQL,
+  your own Anthropic/OpenAI-compatible endpoint, or a local Ollama.
+
+---
+
+## Quick start
+
+```bash
+git clone https://github.com/BaaRai/ARTEX.git
+cd ARTEX
+cp .env.example .env            # set POSTGRES_PASSWORD (and optionally an LLM key)
+docker compose up -d --build    # builds from this checkout, starts PostgreSQL
+```
+
+Open **http://localhost:8787**. On the first visit `/setup` asks for the one-time setup token
+printed at startup:
+
+```bash
+docker compose logs artex | grep "Setup token"
+```
+
+> There is no prebuilt Docker image to pull: the image is always built from your checkout.
+> For all installation paths (script, binaries, source, release archives), see [Installation](#installation).

-## Approval record details
+## How it works

-The global "Approval Records", the in-task "Interception Approvals", and the approval cards in conversations all support expanding to view details. The display structure references the
-[AegisHook approval details component](https://github.com/RuoJi6/AegisHook/blob/main/web/src/components/CallDetail.vue), reusing ARTEX's components and theme:
+### Dual-graph architecture: exploration graph + asset graph

-## Argv prefix rules
+ARTEX separates *what the goals are* from *how far testing has progressed* into two independent
+graphs linked by anchors:

-Besides `string` and `regex`, an interception rule can use `match_type: argv` (Bash only, `match_target: tool_input`). Its pattern is a JSON array of 1 to 8 tokens, for example `["git","push"]`, with no empty token, no token starting with `-` and no shell metacharacter or space.
+- **Asset graph (shared across tasks).** One source of truth for `root_domain / subdomain / ip /
+  service / app / endpoint`, owned by companies. Parent-child relationships and deduplication keys
+  are computed by the program; agents only submit raw observations.
+- **Exploration graph (per task).** The task's reasoning and progress: `goal / intent / fact /
+  finding / hint` nodes connected by `spawns / derived_from / yields / proves` edges into a lineage
+  chain.
+- **Anchors link them.** `exploration_anchors(node_id, asset_id)` ties intents, facts and findings
+  to concrete assets: which assets a direction touched, and which intents tested a given asset.
+  This also powers **asset test coverage** and the coverage graph.

- **It is a prefix rule.** The command is parsed (mvdan.cc/sh, Bash grammar, as the Bash tool runs `bash -c`) and must be one simple command: no pipe, list (`;`, `&&`, `||`), redirection, prefix assignment, subshell, background job, no wrapper program (`command`, `builtin`, `env`, `exec`, `eval`), and no command or process substitution or parameter expansion anywhere. Its prefix (program plus subcommands, from a code-owned arity table: `git push`, `npm run build`, `nmap`) must equal the pattern exactly. Any other form does not match, and the normal flow (judge, approval) continues.
- **Flags are ignored by construction.** `["git","push"]` also covers `git push --force`; a flag before the subcommand (`git -C /repo push`) matches nothing. An allowed prefix does not cover what the program does internally.
- An argv rule takes its place in the priority order like any rule, and the target gate still runs after an argv allow.

+  FD -. anchor .-> EP
+```

+The **planner** reads the exploration graph, judges goals, and dispatches intents only when there
+is an uncovered direction; a **worker** claims one intent, executes it, writes assets/facts/findings
+back into both graphs, then stops.

-## Traffic capture browser extension
+### The engine loop

-The bundled browser extension (`extension/`) turns your own browsing into agent-visible evidence: log into an authenticated target once (captchas, email OTP and 2FA included), and the captured requests/responses land in ARTEX's traffic store like proxy-recorded traffic, ready to search and bind to findings:
+The engine is event-driven: any graph change wakes the planner, workers claim and execute intents,
+write-back triggers the next round, until `prove_goal` closes the task.

- Load the unpacked extension from `extension/` (Chrome/Edge, Developer Mode → Load unpacked);
- In the popup, set your ARTEX URL and token, then press **Start capture** on the tab you are browsing;
- Use the site normally; text requests/responses are batched to `POST /api/traffic/ingest` (authenticated). Binary bodies (images, fonts) are skipped, bodies are truncated at 256 KiB, batches are capped at 50 entries;
- Press **Stop** when done. Everything stays in your local traffic store.

+  P->>DB: read situation (graph_overview prefetch + coverage/scope)
+  P->>FR: dispatch 0..N intents (with asset_ids)

+  W->>FR: claimNext claims one intent

+  W->>DB: write back fact / asset / finding + per-step activity
+  DB-->>EV: graph change
+  EV-->>P: wake again (closed loop)
+```

-Sync asset data directly from [ScopeSentry](https://github.com/Autumn-27/ScopeSentry), avoiding duplicate collection:
+### Durable attack chains, shared worker memory

- On the "**Asset Sync**" page, enter the ScopeSentry address and API Key to connect the data source;
- Choose the targets and asset types to sync by **project** or **task** (domains / subdomains / IPs / ports / sites / endpoints…);
- One-click import, merged by company asset scope, straight into ARTEX's asset graph for agents to explore.
+Real attack chains are multi-step and ordered (find an injection → get credentials → move
+laterally). The planner keeps a **todolist retained per task across wake-ups**: it records the
+chain once, then dispatches the next step only when its prerequisites are satisfied by facts.
+
+Workers can also **search each other's execution traces** (`search_all_worker_traces`,
+`list_worker_traces`, `get_worker_trace`). Observations that never became formal facts (an error
+message, a response snippet, a hidden parameter) are still reusable by the next worker, while each
+worker remains confined to the intent it claimed.
+

+
+## Features
+
+### Evidence, not chat logs
+
+- **Recording MITM proxy** (`:8788`) with a generated CA: every Bash/HTTP tool call is traced, and
+  request/response evidence can be bound to a finding.
+- **Browser extension** (`extension/`) for authenticated targets: log in once (captcha, email OTP,
+  2FA included), capture the session, and the requests/responses land in the same traffic store.
+
+  <details>
+  <summary>Using the traffic capture extension</summary>
+
+  - Load the unpacked extension from `extension/` (Chrome/Edge: Developer Mode → Load unpacked);
+  - In the popup, set your ARTEX URL and token, then press **Start capture** on the tab you are
+    browsing;
+  - Use the site normally; text requests/responses are batched to `POST /api/traffic/ingest`
+    (authenticated). Binary bodies (images, fonts) are skipped, bodies are truncated at 256 KiB,
+    batches are capped at 50 entries;
+  - Press **Stop** when done. Everything stays in your local traffic store.
+
+  </details>
+- **Verified findings**: findings carry a POE level, a verification status and a note; a finding is
+  `verified` only when a bound proof/response and verbatim evidence quotes support it. Gzip/deflate
+  bodies are decoded before the quote check.
+- **Vulnerability retest loop**: a dedicated `retester` agent re-runs a finding with optional fixed
+  version/conditions, records `Still reproducible / Fixed / Cannot confirm`, and can move the
+  finding to `Fixed` automatically. Original evidence and reports are preserved.
+- **Reports and exports**: findings, evidence and task archives, with traffic snapshots kept
+  encrypted at rest.
+
+### Control without slowing down
+
+- **Interception gate**: every tool call can require human approval, with rules by `string`,
+  `regex` or **argv prefix**. An argv rule is a JSON array of 1 to 8 tokens (Bash only, for
+  example `["git","push"]`); it matches only a single simple command whose parsed prefix equals
+  the pattern exactly. Pipes, lists, redirections, prefix assignments, subshells, background jobs,
+  wrapper programs and command/parameter substitutions do not match; flags are ignored by
+  construction (`["git","push"]` covers `git push --force`, but `git -C /repo push` matches
+  nothing). Each approval records who decided: `human`, `rule`, `model` or `system`.
+- **Scope and target gate**: scope rows define the coverage denominator; assets outside the
+  declared scope are not explored. The target gate (off by default, API-only) can refuse
+  destinations that were not approved.
+- **Budgets**: `ARTEX_TASK_BUDGET_TOKENS` / `ARTEX_TASK_BUDGET_TURNS` cap a whole task (planner and
+  workers); `ARTEX_INTENT_BUDGET_TOKENS` / `ARTEX_INTENT_BUDGET_TURNS` cap one worker run. Near the
+  limit the task enters a forced wrap-up; a worker is not started when the remaining budget cannot
+  cover it. Budgets are in memory: a restart starts fresh.
+- **Noise governor**: `ARTEX_NOISE_PROFILE=quiet|balanced|aggressive` paces requests ARTEX sends to
+  targets (per-host rate, burst, in-flight limit, jitter, backoff on 429/503, short GET caching).
+  With a profile set, agents also receive low-and-slow flags for the installed scanners.
+- **Untrusted-output boundary (on by default)**: tool results are framed between nonce-tagged
+  markers so the model treats them as data, not instructions. Disable with
+  `ARTEX_UNTRUSTED_BOUNDARY=0`.
+
+### Assets and coverage
+
+- **Coverage ledger and force-directed coverage graph**: in-scope assets are highlighted as tested
+  or untested, with linked intents, facts and findings per node.
+- **Company-scoped asset graph**: shared across tasks, deduplicated by the program, with
+  domain → subdomain → service → endpoint containment.
+- **ScopeSentry sync**: pull asset data from a
+  [ScopeSentry](https://github.com/Autumn-27/ScopeSentry) instance by project or task, merged by
+  company scope into the asset graph for agents to explore.
+
+  <details>
+  <summary>Syncing from ScopeSentry</summary>

+
+  </details>
+- **Task categories, templates, relations and archives** for repeatable engagements.
+
+### Platform
+
+- **LLM profiles with failover**: Anthropic, OpenAI, OpenAI-compatible relays and keyless Ollama;
+  multiple profiles per task with automatic failover.
+- **Token accounting**: per-task and per-session usage, cache reads/writes, and an LLM record view
+  for every call.
+- **MCP servers, skills, memory and a workspace**: extend the agent with remote tools and reusable
+  prompt/playbook material.
+- **Single binary**: the Next.js UI is embedded with `go:embed`; PostgreSQL is the only external
+  dependency.

-UPX self-extracting binaries may be incompatible with some Linux kernels, virtualization environments, or security policies, so they are disabled by default. Use `ARTEX_TARGETS` to customize the targets; when you have confirmed the target runtime is compatible, explicitly pass `--upx` to further shrink the binary:
-
-```bash
 ARTEX_TARGETS=linux/amd64,windows/amd64 ./build.sh --release
 ./build.sh --target linux/amd64 --upx
 ```

-## Backups
-
-`scripts/backup.sh` dumps the Postgres database (and optionally the data
-directory) with timestamped output and rotation:
-
-```bash
-scripts/backup.sh --with-data          # db dump + data/ archive, keep 14
-scripts/backup.sh --keep 7             # db only, keep 7
-```
-
-Restore a dump into a running stack:
-
-```bash
-gunzip -c backups/artex-db-<timestamp>.sql.gz | docker compose exec -T postgres \
-  psql -U "$POSTGRES_USER" -d "$POSTGRES_DB"
-```
-
-Stored secrets (LLM API keys and proxies, MCP env, task credentials,
-notification channel config, the Brave and Tavily search keys, the web search
-and global proxies, the execution spec of custom tools) are encrypted in the database with the key in `keys/secret.key`
-(generated at first start, mode 0600, next to `jwt.key`). **A database backup
-without that key can no longer restore those secrets**: back up `keys/` with the
-dump, separately. Deployments without a persistent disk set `ARTEX_SECRET_KEY`
-(32 bytes, base64 or hex, e.g. `openssl rand -base64 32`) instead. ARTEX refuses
-to start when the database holds encrypted secrets and no key is available.
-
-Daily cron example (03:20, operator crontab):

-
-## Updating and upgrading
-
-> Upgrading only swaps the program and never touches data: the Postgres volume `pgdata`, `./data` (SQLite, task files, etc.), `./keys` (jwt.key), and `./skills` are all preserved. **No manual database migration is needed**: `artex` idempotently re-runs `schema.sql` on every start (with `ADD COLUMN` / `CREATE INDEX IF NOT EXISTS`), i.e. "restart equals migrate". It is still recommended to back up `./data` and the database before upgrading.
-
-**Update banner (opt-in, off by default)**: start ARTEX with `ARTEX_UPDATE_CHECK=1` to have the backend ask the public GitHub releases API for the latest ARTEX tag, at most once per 24 hours (cached in memory; a failed check is not retried within that window). When the release is newer than the running version, the web UI shows a small dismissible strip linking to the Releases page. The request sends only the `User-Agent: artex-update-check` header. Unset, ARTEX makes no update request and shows no banner.
-
-### Upgrading from a clone made before 2026-10-23
-
-The repository history was rewritten that day to drop a personal email address from the commit metadata. A clone made before then cannot fast-forward, and `./update.sh` now stops instead of silently rebuilding stale code. Recover once, then upgrade normally:
-
-```bash
-git stash                 # only if you have local changes
-git fetch origin
-git reset --hard origin/main
-git stash pop             # only if you stashed
-```
-
-Your data is not affected: `./data`, the `pgdata` volume and `./skills` are not part of the git history.
-
-### Option 1: one-click update script
-
-```bash
-cd ARTEX
-./update.sh
-```
-
-The script first optionally `git pull`s the latest code, then lets you choose **① Docker update** or **② local build update** (matching `install.sh`):
-
- **① Docker**: rebuilds the image from this checkout → `docker compose build artex` → `docker compose up -d artex` (restarting migrates the schema automatically).
- **② Local**: rebuild the frontend static assets → recompile `./artex` (restart the process for it to take effect).
-
-### Option 2: Docker Compose (manual)
-
-```bash
-cd ARTEX
-git pull                       # update compose / scripts
-docker compose build artex     # rebuild the image from this checkout
-docker compose up -d artex     # recreate the container → schema migrates automatically
-docker image prune -f          # clean up old images (optional)
-```
-
-### Option 3: prebuilt binaries (Releases)
-
-Download the new version's zip from [Releases](https://github.com/BaaRai/ARTEX/releases), stop the old process, then overwrite `artex` and `skills/` (keep your `config.json` and `data/`), and restart:
-
-```bash
-cp -r <extracted dir>/skills ./ && cp <extracted dir>/artex ./
-./start.sh
-```
-
-### Option 4: build from source
-
-```bash
-git pull
-cd web && npm ci && npm run build:static && cd ..
-cp -r web/out server/webui/dist
-CGO_ENABLED=0 go build -tags embedui -o artex ./cmd/artex
-# restart ./start.sh
-```
+UPX is disabled by default: self-extracting binaries may be incompatible with some kernels,
+virtualization environments or security policies. Pass `--upx` only after confirming the target
+runtime supports it.

A profile also adds a small jitter, backs off on 429/503 (honouring `Retry-After`, bounded retries, GET/HEAD/OPTIONS only), and, for the http custom tools and the enrich probe, merges identical in-flight GETs of one task (per tool) and caches them briefly (60/30/10 s; never POST, PUT, PATCH or DELETE; WebFetch is paced only), and logs a per-host noise line each minute. `ARTEX_TARGET_USER_AGENT` sets a User-Agent on target requests that carry none, under a profile; empty keeps the current one. Tools launched through Bash are not paced yet.

It tells them to test one host at a time, to back off on 429/503 and never to raise the rate to meet a deadline. Unset or `off`, the block is empty and every prompt is unchanged.

Unset or `0` means unlimited, and nothing changes. A worker is not started when the remaining task budget cannot cover its estimated cost (the average of the task's finished workers, else 50000 tokens and 10 turns). When the remaining budget reaches the wrap-up reserve (the larger of 5% and 20000 tokens, and 2 turns), the task enters a forced wrap-up: the planner writes a summary and the final goal judgment, and workers may only write back (`record_fact`, `insert_assets`, `report_finding`, `update_finding_report`). The task then ends `done` if its goals are met, otherwise `timeout`. Budgets are kept in memory: a restart, or a revive of a finished task, starts a fresh budget. Each planner round logs a `[budget]` line. Practical floor: below 50000 tokens a task gets no worker; from 50000 to about 70000 it typically gets one worker and then the wrap-up. Pick a budget well above 70000 tokens for real exploration.

 ## Development

-### Manual vulnerability retesting
-
-The "Retest" tab on the task details page lets you page through the task's vulnerabilities, review past conclusions and evidence, and manually start a retest. After starting, the current tab keeps its place and shows a spinner with "Retesting"; once the fix is confirmed, the vulnerability status is updated accordingly.
-
-Click "Retest" in the actions area of any row in the vulnerability list, or click "Start Retest" in the "Vulnerability Retest" area of the vulnerability details; fill in the optional fixed version, test conditions, or limits, and the system creates an independent retest agent session while keeping the current page. The flat list, group-by-task, and asset views all support this entry point; while a retest is running, a spinner and "Retesting" are shown: click to enter the corresponding session to watch, and it reverts to "Retest" when finished. Retesting does not require restarting the original scan task; conclusions are "Still reproducible", "Fixed", or "Cannot confirm", and each conclusion, evidence, and session link is saved in the vulnerability details.
-
-On first start, the new backend pre-creates an editable "Vulnerability Retest" (`retester`) agent; you can configure its prompt, LLM, run budget, and tools in Agent management. It uses its bound LLM by default, or the global active configuration when unbound. When a retest session completes successfully with a "Fixed" conclusion, the system automatically sets the vulnerability's handling status to "Fixed"; running, failed, stopped, or other conclusions keep the original status. Original evidence and reports are always preserved. You can also manually select "Fixed" from the status dropdown. While the same vulnerability is being retested, the existing session is reused; after a stop, failure, or service restart, you can start it again.
-
-In this version, history is viewed via vulnerability details and sessions; it is not yet included in vulnerability report exports or task archive packages, and is not automatically linked to traffic captures. Demo mode only generates clearly labeled simulated records and never requests real targets.

-### Dual-graph architecture: exploration graph + asset graph
-
-The system splits "**what the goals are**" and "**how far testing has progressed**" into two mutually independent graphs linked by anchors:
-
- **Asset Graph (globally shared)**: a single source of truth for assets shared across tasks. Nodes are `root_domain / subdomain / ip / service / app / endpoint`, owned by companies; the parent-child relationships domain→subdomain→service→endpoint and the dedup keys are all computed by the program: agents only submit raw information.
- **Exploration Graph (per-task)**: the "thinking and advancing" process of one task. Nodes are `goal` / `intent` / `fact` / `finding (vulnerability)` / `hint`, connected by edges like `spawns / derived_from / yields / proves` into a **lineage chain**, answering "which directions derive from which facts, and what they produced".
- **The two graphs are linked by anchors**: `exploration_anchors(node_id, asset_id)` anchors intents/facts/vulnerabilities to concrete assets: so you can see which assets an exploration direction hits, and conversely look up from a given asset which intents tested it in this task and which facts were derived. This also powers **asset test coverage** and the **asset coverage graph** (in-scope assets + tested highlights).
-

-
-> Division of labor: the **planner** reads the exploration graph's situation, judges goals, and dispatches **intents** into the frontier only when there are uncovered new directions; a **worker** claims **one intent**, executes with real tools, writes new assets/facts/vulnerabilities back into both graphs, then stops. The asset graph is shared facts; the exploration graph is the per-task advance chain.
-
-### Engine and intent lifecycle (the closed loop of one exploration)
-
-The engine is an **event-driven** closed loop: any graph change wakes the planner, the planner dispatches intents, workers claim and execute intents and write back, and the write-back triggers the next round, until the goal is proven (`prove_goal`).
-
-```mermaid
-sequenceDiagram
-  autonumber
-  participant EV as graph-change debounce
-  participant P as planner
-  participant FR as frontier intent queue
-  participant W as worker
-  participant PX as recording proxy
-  participant DB as dual graphs + activity
-
-  EV-->>P: wake up
-  P->>DB: read situation (graph_overview prefetch + coverage/scope)
-  P->>FR: dispatch 0..N intents (with asset_ids)
-  Note over P,FR: most wake-ups dispatch 0 (no new direction means done)
-  W->>FR: claimNext claims one intent
-  W->>DB: fetch the raw assets of the intent's asset_ids as initial information
-  W->>PX: real tool execution (Kali / Bash / HTTP)
-  PX-->>W: response (fully traced + CA verified)
-  W->>DB: write back fact / asset / finding + per-step activity
-  DB-->>EV: graph change
-  EV-->>P: wake again (closed loop)
-```
-
-### Process-level information exchange between workers
-
-During a deep exploration, many valuable observations (an error, a response snippet, a hidden parameter) appear in a worker's **execution process** but may never be written as formal facts. To avoid duplicate work and let workers on the chain stand on each other's shoulders, workers can **search processes across works**:
-
- `search_all_worker_traces(q)`: keyword-search the **execution processes of other works in this task** (automatically excluding the steps of your own intent); hits carry `intent_id`;
- `list_worker_traces` / `get_worker_trace(intent_id, step_ids=[…])`: first see which works have run, then fetch the full content of specific steps of a given work for detailed exchange.
-
-This way, even before a corresponding fact exists on the exploration graph, later workers can reuse observations from others' processes: **information flows between workers at "execution process" granularity**, while the boundary stays the same (each worker still only works on the intent it claimed).
-
-```mermaid
-flowchart LR
-  WA["worker A (intent #12)"] -->|"per-step activity"| ACT[("exploration graph · activity process store")]
-  WB["worker B (intent #34)"] -->|"per-step activity"| ACT
-  WC["worker C (intent #56)"] ==>|"1) search_all_worker_traces(q)"| ACT
-  ACT ==>|"2) hits on A/B steps (self excluded)"| WC
-  WC ==>|"3) get_worker_trace(id, step_ids)"| ACT
-  ACT ==>|"4) returns full process content"| WC
-```
-
-### The planner's multi-round shared todolist → stable attack chains
-
-Real attack chains are usually **multi-step sequences with dependencies** (e.g.: find an injection point → obtain credentials → move laterally → escalate privileges); dispatching them all in parallel at once would only cause chaos. The planner therefore keeps a **planning todolist that is retained per task and shared across wake-ups**:
-
- The planner is event-driven, woken on every graph change, but **each wake-up is a brand-new session**; the shared todolist lets it **record a serial exploitation chain once**, then **dispatch intents step by step by dependency** over subsequent rounds, instead of pre-expanding the whole chain in a single round;
- Each round only dispatches intents for next steps whose "prerequisite steps are complete and the facts they depend on exist", and updates the list as progress happens (marking steps satisfied by facts as done).
-
-```mermaid
-flowchart TB
-  subgraph TODO["Shared todolist (retained per task · persists across wake-ups)"]
-    direction LR
-    T1["1 injection point  [done]"]
-    T2["2 get credentials  [in progress]"]
-    T3["3 lateral movement  [pending prerequisite]"]
-    T4["4 privilege escalation  [pending prerequisite]"]
-    T1 -.prerequisite met.-> T2 -.-> T3 -.-> T4
-  end
-  R1["round 1 wake-up  dispatch intent ①"] --> T1
-  R2["round 2 (① produced a fact)  dispatch intent ②"] --> T2
-  R3["round 3 (② produced a fact)  dispatch intent ③"] --> T3
-```
-
-Thus, even in an "event-driven + stateless session" environment, the attack chain still **advances steadily, without repetition or reordering**: this is the key to ARTEX autonomously completing multi-step exploitation chains.

+# Security Policy
+
+## Supported Versions
+
+ARTEX is an autonomous penetration-testing tool. Security fixes are provided only for the latest official release line. The `main` branch is not considered a stable release and may change at any time.
+
+Only the latest release line receives security fixes. Older releases do not receive fixes; please upgrade to the latest release.
+
+Notes:
+- Please upgrade to the latest release before reporting a vulnerability.
+- Forks, custom builds from arbitrary commits, and modified versions are not covered by official support.
+
+## Reporting a Vulnerability
+
+**Do not open a public issue for a security vulnerability.**
+
+Report through **GitHub Security Advisories**: **Security** tab → **Report a vulnerability** in the `BaaRai/ARTEX` repository. This is the only reporting channel.
+
+Please include:
+- A description of the vulnerability and its expected impact.
+- The ARTEX version and/or commit hash.
+- Runtime environment (OS, Docker/local, PostgreSQL, LLM provider, etc.).
+- Minimal reproduction steps (PoC).
+- Logs, screenshots, or sample traffic with **sensitive data removed**.
+- Suggested remediation, if available.
+
+**Do not send** real third-party data, credentials, tokens, customer data, or unredacted sensitive content.
+
+## Scope and Authorized Testing
+
+ARTEX is an offensive-security tool. Test only against:
+- Your own ARTEX deployment in a lab or local environment;
+- Systems you own;
+- Targets explicitly authorized in writing (bug bounty, pentest contract, etc.).
+
+Testing, scanning, or exploiting third-party systems without explicit authorization is strictly prohibited. Reports that violate this principle may be closed without action.
+
+## What to Expect
+
+This is an open-source project maintained on a best-effort basis. We aim to acknowledge a report within about a week and keep you updated, but we cannot guarantee specific response or fix timeframes.
+
+## If a Report Is Accepted
+
+- We will open a private **GitHub Security Advisory** for coordination.
+- We will identify the release containing the fix when it is published.
+- We may request a **CVE** if the vulnerability qualifies.
+- We will credit you or your organization in the advisory if you wish.
+- Default disclosure timing: **90 days** after a fix is available, or earlier by mutual agreement. If the vulnerability is being exploited in the wild, we may disclose earlier.
+
+## If a Report Is Declined
+
+We will explain the reason, for example:
+- It is not a security vulnerability but intended behavior.
+- It is outside ARTEX’s scope (e.g., an issue in an LLM provider, PostgreSQL, Docker, or a browser).
+- There is insufficient information to reproduce it.
+- The report only states that “the tool can be misused” without identifying a specific technical flaw in ARTEX.
+
+Where appropriate, we may convert the report into a public hardening issue or feature request.
+
+## Out of Scope
+
+The following are generally **not** considered ARTEX security vulnerabilities:
+- Attacks or scans against systems you do not own or are not authorized to test.
+- Self-XSS, spam, or brute-force without real impact.
+- Large-scale DoS/DDoS or resource-exhaustion attacks.
+- Social engineering targeting maintainers or users.
+- Issues that exist only in third-party dependencies and do not affect ARTEX.
+- Reports that “ARTEX can be used to attack systems” when the user has valid authorization — this is the nature of a penetration-testing tool, not a vulnerability.
+- Missing headers or hardening configuration without a concrete security impact.
+
+## Safe Harbor
+
+We welcome ethical security research. If you follow this policy and test only within authorized scope, we will not pursue legal action against you for good-faith research. This does not exempt you from applicable laws in your jurisdiction.
+
+## Disclosure Policy
+
+- Do not publicly disclose vulnerability details before a fix is available or before the coordinated disclosure period ends.
+- Do not publish a public PoC without maintainer consent.
+- If you do not receive a response within a reasonable time, please ping the contact channel above before disclosing.
+
+Thank you for helping make ARTEX safer.

Author	SHA1	Message	Date
BaaRai	ac6e2b3c44	feat(egress): change the noise profile at runtime The egress governor is now a current governor that SetProfile swaps: new requests use the new one, requests in flight finish on the old one, and one package-level ticker logs the counters of the current governor. WebFetch, the http custom tools and the enrich probe resolve it per request, and the agent prompt block reads the current profile. The noise_profile setting (off, quiet, balanced, aggressive) is applied at startup and wins over ARTEX_NOISE_PROFILE, which stays the fallback; PUT /api/settings validates, stores and applies it without rebuilding agents, and GET /api/settings/noise returns the per-host counters without resetting them. System settings gets a Target noise card.	2026-11-14 23:30:06 +01:00

BaaRai	8f5a67d10c	fix(intercept): destructive commands score high; chunk batch decisions to the server limit The destructive shell signal is worth 60 instead of 50, so a destructive command alone scores 10 + 60 = 70, high. The level thresholds are unchanged. The approvals page sends the selection in sequential calls of at most 100 ids, the server limit (maxBatchDecide), instead of one call that the server would refuse with 400 when more than 100 rows are selected. If a call fails, sending stops: its ids and the later ones stay selected with the error, and ids already decided stay decided. The final toast gives the totals.	2026-11-14 22:46:18 +01:00
BaaRai	d8f3c7aec2	feat(intercept): deterministic risk score and batch approval ScoreRisk scores a pending tool call from fixed, additive signals (no model): shell destructive, privilege, secret, exfiltration, reverse shell, scanner and file-write patterns; file writes with a sensitive-path bonus; web reads with a mutating-method bonus; MCP, unknown tools and unreadable input never score low. The score is computed when a pending row is read and returned as risk next to the unchanged row fields. POST /api/intercept/pending/batch-decide decides up to 100 ids, each through Interceptor.Decide with the same approver and address as a single decision, and reports a result per id. The approvals page gets row selection, a confirmation that counts high-risk rows, per-id errors, and a risk badge with its reasons.	2026-11-14 22:19:09 +01:00
