fix(db): stop billing cache writes twice in profile cost

Norma normalizes InputTokens to input + cache read + cache write, so both cache buckets are subsets of it. The fresh share billed at the input price is now input minus reads minus writes, still clamped at zero for gateways that report disjoint buckets.

 All notable changes to this project are documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
+## [Unreleased]
+
+### Added
+
+- **Target noise governor**: one shared egress governor paces ARTEX's own HTTP requests (WebFetch, the http custom tools and the enrich probe) against a noise profile (`off` by default, `quiet`, `balanced`, `aggressive`): a per-host token bucket with jitter, per-host and global in-flight caps, 429/503 backoff, GET deduplication with a short cache, and a configurable target User-Agent (`ARTEX_TARGET_USER_AGENT`). Off is a strict passthrough (#205).
+- **Low-and-slow prompt block**: when a noise profile is set, the planner, worker, main agent and chat prompts carry the per-host limits of the profile and the exact rate or delay flags for nmap, nuclei, httpx, katana, ffuf, dalfox and sqlmap; with the profile off the prompts are unchanged (#212).
+- **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 (#233).
+- **Bash requests paced through the capture proxy**: with traffic capture on, the Bash proxy URL carries a marker userinfo. The recording proxy paces each request of a marked connection by the noise profile's per-host rate and jitter, and counts it, before it goes upstream. This applies inside CONNECT tunnels too. WebFetch, the http custom tools and enrich keep the unmarked URL and are not paced twice. The proxy now drops `Proxy-Authorization` from every request it forwards or records. This is best effort: only clients that honour the proxy are covered, with capture on (#234).
+- **Hierarchical budgets**, off by default: a task budget and a per-intent budget take the minimum of their own budget and the parent's remaining budget above the wrap-up reserve, planner calls count inside the task, and reaching the reserve forces a wrap-up (#206).
+- **Coverage ledger**: the worker records what it examined, ruled out or left open for each surface and risk class with `record_coverage`; gaps, unexamined classes and completeness appear in the planner context, `GET /api/tasks/{id}/coverage`, the coverage card and the Markdown report (#207).
+- **Closed-question judge**: the LLM fallback judge answers eight fixed questions that the code owns and the code takes the decision; every failure now leads to ask instead of allow, and the previous behaviour stays available as `llm_judge_mode = freeform` (#208).
+- **argv interception rules**: a new `match_type = argv` matches the parsed prefix of a Bash command exactly, and a pending Bash approval can create such a rule in one click; a code-owned denylist refuses programs where a prefix would allow arbitrary code (#210, #211).
+- **Scanner output ingestion**: `ingest_scan_output` parses nmap XML, nuclei JSONL, httpx JSONL and ffuf JSON, and writes assets and facts deterministically, so the model never reads the raw output (#214, #215).
+- **bbot ingestion**: a typed parser splits bbot JSONL events by `scope_distance`, only in-scope events go through `insert_assets`, and `ingest_bbot` reads the file line by line with a 64 KiB cap (#199, #200).
+- **Tool RAG**, off by default: when the bound tool list of an agent is large, only the subset relevant to the current intent is injected, as a projection that never adds or edits a tool (`ARTEX_TOOL_RAG`) (#204).
+- **Fact provenance**: `record_fact` takes a closed `source` enum (default `inference`) and every fact carries the server-set `origin`, both shown in `recent_facts`, `list_facts` and `expand_digest` (#194).
+- **Per-message nonce envelope**: agent- and target-derived fields reach the planner and worker user messages inside a code-owned data envelope with a random nonce per message; operator input stays outside it (#195).
+- **Intercept risk score and batch approval**: a deterministic risk score (low, medium, high) is shown on each pending approval, and up to 100 pending decisions can be settled in one call, each through the existing single-decision path (#232).
+- **`ask_operator` target warning**: a request whose question names a host or URL outside the goal targets is tagged as containing target-derived text (#197).
+- **Opt-in update banner**: `ARTEX_UPDATE_CHECK` makes the backend check the latest GitHub release at most once per 24 hours and the UI show a banner; off by default (#202).
+- **Release provenance**: release archives carry GitHub build provenance attestations and a CycloneDX SBOM (`gh attestation verify <zip> --repo BaaRai/ARTEX`); release notes are the matching `CHANGELOG.md` section (#219, #201).
+
+### 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); the default flips here (#203).
+- **Versioned migrations**: the `db` package applies numbered `db/migrations/NNNN_slug.sql` files once, in order, under the schema advisory lock, and records a SHA-256 checksum in `schema_migrations`; missing, renamed, changed or out-of-order migrations fail closed (#226).
+- **Coverage graph performance**: the coverage graph batches its connector lookups (three queries instead of one per root and per company) and adds the partial index `idx_ts_icp`; on a task of about 3,000 assets the p50 dropped from 126 ms to 27 ms and the queries per call from 221 to 3 (#230).
+
+### Fixed
+
+- **Auto-scope hygiene**: auto `task_scope` rows count for coverage and untested assets only under a declared root, and direct coverage counts anchored assets through fact anchors only; the scope is described as "coverage scope, not enforced" (#196).
+- **Enrich HTTP probe**: it now dials through `intercept.PinnedDialer`, so the target gate applies and a probe without a target scope is refused (#198).
+- **Agent hook data races**: the eight package-level hooks are synchronised, so a second wire-up no longer races tasks that already read them (#227).
+
+### Security
+
+- **Secrets at rest**: the credential-bearing columns and settings (LLM API keys and proxy, task credentials, MCP server env, notification channel config, search and proxy settings), the exec spec of custom tools and the evidence snapshot heads are encrypted in PostgreSQL with AES-256-GCM (`enc:v1:`) using `ARTEX_SECRET_KEY`, else `keys/secret.key`; existing plaintext rows are backfilled once at startup, and a missing or wrong key while encrypted data exists refuses to start. This protects database dumps and backups, not a running instance (#213, #216, #217, #218).
+- **URL credentials are dropped before storage**: scan and bbot ingestion, the asset store and archive restore strip URL userinfo, so `https://user:pass@host/app` is stored and matched as `https://host/app` (#222, #223, #224).
+
 ## [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.

+# 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.
