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.

+- **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).

 ## [0.6.0] - 2026-11-12
 
 Machine-checked finding verification (S1), intercept decisions traced to their actor, configurable notification limits, prompt hardening and goal guards from the #124 agentic audit, the target gate (S3b phase 1 and step 2.1, off by default and API-only), intent claim leases, and checksum-verified tool downloads in the Docker image.

 **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.

+# 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.
