perf(db): batch coverage-graph lookups and index icp scope probes

BuildCoverageGraph issued one QueryRow per connector root domain and one per company: 221 statements for a task scoped by 800 subdomains over 200 roots and 20 companies. Fetch them with one ANY() query each. The coverage target join probes task_scope once per asset, and the icp branch fell back to uq_task_scope_v2 with only kind as index condition; migration 0003 adds a partial index on task_scope(value) for icp rows. Large-fixture invariants test and benchmark included.

 **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.

 **Noise profile (off by default)**: `ARTEX_NOISE_PROFILE` paces the requests ARTEX itself sends to targets (WebFetch, http custom tools, the enrich probe). Unset or `off`, nothing changes: no limit, no cache. Set `quiet` (2 req/s per host, burst 4, 1 in flight), `balanced` (5 req/s, burst 10, 2 in flight) or `aggressive` (20 req/s, burst 40, 4 in flight), e.g. `ARTEX_NOISE_PROFILE=balanced` in `.env` or the environment. 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.
 
+**Low-and-slow agent guidance (off by default)**: when a noise profile is set, the planner, worker, main agent and chat agents receive a code-owned prompt block with the profile's per-host limits and exact rate/delay flags for the scanners installed in the image (`nmap`, `nuclei`, `httpx`, `katana`, `ffuf`, `dalfox`, `sqlmap`). 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. Commands launched through Bash are not paced by the governor, so these flags are the brake for scanners.
+
 **Run budgets (off by default)**: `ARTEX_TASK_BUDGET_TOKENS` and `ARTEX_TASK_BUDGET_TURNS` cap a task's total spend (its planner rounds and all its workers); `ARTEX_INTENT_BUDGET_TOKENS` and `ARTEX_INTENT_BUDGET_TURNS` cap one worker run. 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.
 
 **Common flags**: `./start.sh -addr :8787 -proxy :8788` (`-addr` frontend+API, `-proxy` traffic recording proxy). The startup script passes arguments through to `artex` verbatim.

+# 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.
