fix(tui): show the actual subscription provider in the Go TUI

The Go TUI rewrite hardcoded "ChatGPT subscription" in the stats view and its
snapshot only carried a boolean, so a Grok run was labeled ChatGPT — the same
bug previously fixed on the Python side. Carry the provider label through the
snapshot protocol and render it, falling back to a generic "Subscription".

utils._subscription_label becomes public subscription_label since the TUI
backend now needs it too.

-## Workspace files
-
-Instructions become part of the prompt. To give Strix a file to work with, such
-as a wordlist, an API specification, or notes, use `--workspace-file`. Strix
-places the file into the sandbox workspace before the scan starts.
-
-```bash
-strix --target https://app.com --workspace-file ./wordlist.txt
-```
-
-The file lands at `/workspace/<file name>`. To choose the destination, write
-`PATH:DEST`. `DEST` is a path inside `/workspace`.
-
-```bash
-strix --target https://app.com \
-  --workspace-file ./openapi.yaml:specs/openapi.yaml \
-  --workspace-file ./notes.md
-```
-
-Repeat the option for every file you want to place. Strix lists the files in the
-agent task, so the agent knows where to read them.
-
-Rules that apply to every workspace file:
-
-- The file is read-only inside the sandbox.
-- The destination must stay inside `/workspace`.
-- The destination must not fall inside a target directory, because target files
-  come from the target itself. Strix skips such a file and logs a warning.
-- Two files cannot claim the same destination.
-
-<Note>
-A workspace file is data for the agent to use. It is not a scan target, and its
-contents do not change the instructions.
-</Note>
-
-<Warning>
-Do not place secrets in a workspace file. The sandbox runs untrusted target
-code, so treat anything you place there as readable by the target.

-# Azure and Microsoft Entra Security
-
-Azure security spans two related but distinct control planes:
-
-- **Microsoft Entra ID** (formerly Azure AD): tenant identity, users, groups, applications, service principals, directory roles, authentication, and Conditional Access.
-- **Azure Resource Manager (ARM):** management groups, subscriptions, resource groups, resources, Azure RBAC, managed identities, and service-specific control/data planes.
-
-Do not equate an Entra directory role with an Azure resource role. A principal can be weak in one plane and privileged in the other, and many escalation paths cross between them.
-
-## Scope and Identity Baseline
-
-Record before testing:
-
-- tenant ID, cloud environment, management groups, subscriptions, and directories in scope
-- current user/service principal/managed identity object ID and home tenant
-- direct and group-derived Entra directory roles
-- Azure role assignments, scope, inheritance, conditions, and deny assignments
-- authentication method, token audience, Conditional Access result, and PIM activation state
-- test versus production subscriptions and any cross-tenant/B2B context
-
-Start with native CLI context:
-
-```bash
-az cloud show --output json
-az account show --output json
-az account list --all --refresh --output json
-az account management-group list --no-register --output json
-az ad signed-in-user show --output json
-az role assignment list --subscription <subscription-id> --all --include-inherited --output json
-az role assignment list --subscription <subscription-id> --assignee <user-object-id> --all --include-inherited --include-groups --output json
-az role definition list --subscription <subscription-id> --output json
-```
-
-For a service principal, `az ad signed-in-user show` does not apply; resolve the current client/service-principal object explicitly from the reviewed credential context. `--all` remains scoped to the selected subscription, and `--include-groups` depends on Microsoft Graph and can still miss nested or workload-derived paths. Repeat the inventory per tenant, management-group root, and in-scope subscription. Never infer identity only from a display name.
-
-## Azure RBAC
-
-An Azure role assignment joins three elements: a security principal, a role definition, and a scope. Scope inheritance runs from management group to subscription to resource group to resource.
-
-### Review
-
-- Enumerate direct, group-derived, inherited, eligible, and active assignments separately.
-- Expand custom role `Actions`, `NotActions`, `DataActions`, and `NotDataActions`; the role name is not a reliable summary.
-- Inspect assignment conditions/ABAC, deny assignments, management-group inheritance, and cross-tenant principals.
-- Identify broad scopes for Owner, Contributor, User Access Administrator, Role Based Access Control Administrator, and custom equivalents.
-- Check who can write role assignments, role definitions, policies, locks, deployments, managed identities, credentials, or compute configuration.
-- Distinguish ARM control-plane permission from service data-plane permission. Contributor over a resource may still gain its data through code/configuration or a managed identity even without direct data actions.
-
-### High-Value Cross-Plane Paths
-
-- Active Microsoft Entra Global Administrator can elevate into Azure by using `Microsoft.Authorization/elevateAccess/action` to grant User Access Administrator at the root `/` scope. That root assignment can persist after PIM deactivation until it is explicitly removed.
-- `Microsoft.Authorization/roleAssignments/write` or equivalent role-management authority → grant a stronger role at an allowed scope.
-- Ability to modify a VM, VM extension, Function App, App Service, Container App, Automation runbook, deployment script, Logic App, or similar workload → execute in that workload's identity and network context.
-- Ability to attach or replace a user-assigned managed identity, together with the host resource write path and `Microsoft.ManagedIdentity/userAssignedIdentities/assign/action` → inherit its downstream Azure permissions.
-- Ability to modify federated identity credentials, app credentials, certificates, or owners → impersonate a service principal/application.
-- Ability to read deployment outputs, app settings, runbook variables, storage, snapshots, disks, backups, or diagnostic settings → recover credentials or sensitive data.
-- Broad policy/deployment rights at a parent scope → affect many child resources even when individual resource assignments appear narrow.
-
-Model each path using exact principal, action, resource, scope, condition, and resulting effective permission. Check Azure Policy and deny assignments before declaring a theoretical path exploitable.
-
-## Privileged Identity Management (PIM)
-
-[Microsoft Entra Privileged Identity Management](https://learn.microsoft.com/en-us/entra/id-governance/privileged-identity-management/pim-configure) provides time-based and approval-based activation for privileged access. It can govern Microsoft Entra roles, Azure resource roles, and PIM for Groups.
-
-PIM terminology:
-
-- **eligible:** the principal must activate before using the role
-- **active:** the principal can use the role without activation
-- **permanent/time-bound:** duration of eligibility or assignment
-- **activated:** a currently active, time-limited instance created from eligibility
-
-### What to Test
-
-- Permanent active assignments where eligible/JIT access is expected.
-- Permanent eligibility without access reviews, expiration, or a business need.
-- Roles that activate without MFA, approval, justification, notification, or a short duration.
-- Approvers who can approve themselves indirectly, lack separation of duties, or no longer own the system.
-- Group-based eligibility where group ownership/membership can be changed by a lower-privileged principal.
-- PIM for Groups on role-bearing groups where a lower-privileged principal can alter ownership, membership, or activation controls.
-- PIM settings applied to one privileged role but omitted from a custom/equivalent role.
-- Directory-role PIM configured while equivalent Azure resource roles remain permanently active, or vice versa.
-- Standing service-principal/workload access. Eligible Azure RBAC via PIM is a user-centric control; service principals and managed identities remain standing or time-bounded active assignments, not user-style eligible activations.
-- Activation sessions that remain useful through cached tokens, active sessions, delegated jobs, or downstream credentials after the intended window.
-- Audit/alert coverage for assignment, activation, approval, renewal, extension, and role-setting changes.
-
-With sufficient Microsoft Graph read permissions, compare current schedule instances:
-
-```bash
-az rest --method GET \
-  --url 'https://graph.microsoft.com/v1.0/roleManagement/directory/roleEligibilityScheduleInstances?$expand=principal,roleDefinition'
-
-az rest --method GET \
-  --url 'https://graph.microsoft.com/v1.0/roleManagement/directory/roleAssignmentScheduleInstances?$expand=principal,roleDefinition'
-```
-
-Those endpoints cover Microsoft Entra role schedules. Follow `@odata.nextLink`, and record the exact Graph permissions or delegated role used because weak tokens silently under-enumerate. Azure resource-role PIM is exposed through ARM's `Microsoft.Authorization` role eligibility/assignment schedule resources; keep the two inventories separate:
-
-```bash
-az rest --method GET \
-  --url "https://management.azure.com/subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleEligibilityScheduleInstances?api-version=2020-10-01&\$filter=atScope()"
-
-az rest --method GET \
-  --url "https://management.azure.com/subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleAssignmentScheduleInstances?api-version=2020-10-01&\$filter=atScope()"
-```
-
-Follow `nextLink` there as well. For Entra directory-role inventory, reviewed readers commonly need `RoleEligibilitySchedule.Read.Directory` and `RoleAssignmentSchedule.Read.Directory` or an equivalent delegated role/application permission set.
-
-## Conditional Access and Authentication
-
-[Conditional Access](https://learn.microsoft.com/en-us/entra/identity/conditional-access/overview) is Entra's identity-driven policy engine and is evaluated after first-factor authentication.
-
-Review:
-
-- policies in on/off/report-only state and coverage of users, groups, roles, applications, authentication contexts, and workload identities
-- exclusions for break-glass accounts, admins, service accounts, guest users, locations, devices, or applications
-- admin and management surfaces not covered by phishing-resistant MFA or appropriate authentication strength
-- legacy authentication and non-interactive flows that do not receive the intended policy
-- device compliance/join trust, named locations, sign-in/user risk, session lifetime, continuous access evaluation, and token protection where used
-- policy gaps caused by nested groups, guest/home tenant behavior, service principals, managed identities, or application-specific grant paths
-- whether emergency access exclusions are narrowly scoped, monitored, credential-protected, and exercised
-
-For workload identities, Conditional Access applies only in limited cases: directly targeted tenant-owned single-tenant service principals can be controlled, but managed identities, Microsoft-owned service principals, most third-party SaaS service principals, and multitenant app registrations do not inherit human MFA semantics. Target the enterprise application service-principal object, not just the app registration, and verify the control at token issuance.
-
-Use sign-in logs and the Conditional Access result to distinguish policy non-application from policy failure. Report-only evaluation is evidence of intended future control, not enforcement.
-
-## Applications, Service Principals, and Workload Identity
-
-An app registration is the tenant-level application definition; a service principal is the local security principal representing an application instance in a tenant.
-
-Inventory:
-
-- owners of application and service-principal objects, separately
-- delegated versus application permissions and admin consent
-- client secrets/certificates, expiry, unused/stale credentials, and credential-add rights
-- federated identity credentials: issuer, subject, audience, repository/branch/environment claims
-- multitenant applications, publisher verification, consent grants, and cross-tenant access settings
-- service-principal role assignments in both Entra and Azure
-- automation/CI connections and whether test identities can reach production
-
-Keep application-object authority separate from service-principal authority. Application ownership and `Application.ReadWrite.*` can add owners, client secrets, certificates, or federated credentials on the app object; service-principal ownership and `ServicePrincipal.ReadWrite.*` govern the enterprise application instance. Admin consent is a separate control plane from credential management. Also trace group ownership/membership where a role-bearing group grants app, vault, Azure RBAC, or Entra role access. A secret's metadata proves age/expiry but not that its value is retrievable.
-
-### Managed Identities
-
-Managed identities remove stored credentials but still carry authority:
-
-- **system-assigned:** lifecycle is tied to one Azure resource
-- **user-assigned:** independent resource assignable to multiple workloads
-
-Enumerate identity attachments and downstream role assignments. Check who can attach/detach the identity, execute or deploy code in the host workload, access its metadata/token endpoint, or reuse a user-assigned identity across environments. Treat workload control as potential identity control.
-
-## Storage and SAS
-
-A Shared Access Signature (SAS) delegates access to Azure Storage through a signed URI. Review:
-
-- SAS type: user delegation, service, or account SAS
-- services/resource types, permissions, start/expiry, protocol, IP restriction, and stored access policy
-- long-lived tokens in source, CI logs, tickets, browser history, application settings, or public URLs
-- account-key use, `listKeys` authority, and key-rotation feasibility
-- public container/blob access, anonymous listing, network rules, private endpoints, and trusted-service exceptions
-- storage RBAC and whether principals can generate user-delegation keys or list account keys
-
-Microsoft recommends a user delegation SAS where supported because it is secured with Entra credentials rather than the account key. User delegation keys and SAS values are time-limited and user-scoped; service/account SAS values derive from account keys, and only service SAS can bind to stored access policies. User delegation SAS is limited to Blob/Data Lake and has a maximum seven-day validity per delegation key. A SAS is a bearer credential; possession can be sufficient even when the holder has no visible Azure role assignment.
-
-Validate each token against its signed permission/resource/time restrictions. Do not treat a redacted or expired SAS found in code as current unauthorized access.
-
-## Key Vault, Secrets, and Certificates
-
-- Determine whether the vault uses Azure RBAC or legacy access policies. The active model is controlled by `enableRbacAuthorization`; RBAC mode invalidates access-policy evaluation for data-plane access.
-- Enumerate who can read secrets, keys, and certificates; who can change access; and who controls workloads with vault-reading identities.
-- Review public network access, firewall/private endpoints, soft delete, purge protection, logging, secret expiry, and rotation.
-- Distinguish key operations (sign/decrypt/wrap) from key export and secret-value read.
-- Look for vault references copied into app settings without corresponding identity isolation.
-- Test backup/restore and cross-subscription permissions where in scope.
-
-Legacy access-policy write authority on the vault resource can still become self-granting in access-policy mode. In RBAC mode, the equivalent finding depends on `DataActions` or role-assignment control, not on legacy access-policy mutation.
-
-## Credential-Equivalent Actions
-
-Treat the following as credential-equivalent or near-equivalent authority when the downstream scope matches:
-
-| Surface | Action or state | Why it matters |
-|---|---|---|
-| Azure RBAC | `Microsoft.Authorization/roleAssignments/write` | grants new authority directly |
-| Root scope | `Microsoft.Authorization/elevateAccess/action` | bridges Entra Global Administrator into Azure root access |
-| Managed identity | host config write plus `.../userAssignedIdentities/assign/action` | attaches a stronger identity to attacker-controlled code |
-| App object | add secret/cert/federated credential or owner | permits application impersonation |
-| Service principal | add credential/owner or modify federation | permits enterprise-app impersonation |
-| Storage | `listKeys` or account-key disclosure | enables service/account SAS and broad account access |
-| Storage | `generateUserDelegationKey` with matching data rights | enables user delegation SAS issuance |
-| Key Vault | secret-value read, key sign/decrypt/wrap, or self-grant path | grants equivalent access even without export |
-
-## Compute, Network, and Data Services
-
-- VM extensions, Run Command, serial console, disks/snapshots, images, custom script, and boot diagnostics
-- App Service/Functions deployment slots, publishing credentials, SCM/Kudu, app settings, storage mounts, and managed identities
-- AKS control plane/RBAC, workload identity federation, kubeconfig retrieval, node/resource-group rights, and private API reachability
-- Container Apps/ACI environment variables, registries, identities, revisions, and exec surfaces
-- Automation accounts/runbooks, Logic Apps/connectors, Data Factory linked services, deployment scripts, and DevOps/service connections
-- NSGs, route tables, public IPs, load balancers, private endpoints, DNS, peering, Bastion, firewalls, and JIT VM access
-- SQL, Cosmos DB, Storage, Service Bus, Event Hubs, and other service-specific data-plane authorization
-
-Map whether a principal that lacks direct data access can reconfigure networking, identity, code, diagnostics, export, backup, or deployment to gain an equivalent capability.
-
-## Testing Methodology
-
-1. **Establish context** — tenant, subscription, cloud, principal, token audience, and active PIM state.
-2. **Inventory both role planes** — Entra directory roles and Azure resource roles with groups, scope, inheritance, conditions, eligible/active state, and custom definitions.
-3. **Map identity objects** — applications, service principals, managed identities, owners, credentials, federation, and consent.
-4. **Review policy gates** — Conditional Access, authentication methods, PIM settings, Azure Policy, deny assignments, and network restrictions.
-5. **Enumerate workloads/data** — identify where control-plane modification yields code execution, identity use, secrets, backups, or data-plane access.
-6. **Build effective-access paths** — principal → permission → resource change/identity → downstream privilege or data.
-7. **Cross-check logs** — Entra sign-in/audit, PIM, Azure Activity, resource logs, and Defender/Sentinel alerts where available.
-8. **Re-evaluate boundaries** — guest/home tenant, management-group inheritance, test/production, group ownership, and workload identities.
-
-## Validation
-
-For each finding, include:
-
-1. tenant/subscription and exact principal/object IDs
-2. assignment source, role definition, scope, inheritance, condition, and PIM state
-3. relevant Conditional Access/authentication result
-4. exact Azure/Graph action and target resource
-5. effective permission or cross-plane path demonstrated
-6. policy, deny, network, licensing, or configuration prerequisites
-7. audit/sign-in/activity evidence and remediation at the correct control plane
-
-## Common False Positives
-
-- Role name appears privileged but custom `Actions`/`DataActions`, conditions, scope, or deny assignments block the claimed action.
-- Contributor is reported as able to assign roles without `roleAssignments/write` or an alternate workload/identity path.
-- An eligible PIM assignment is described as standing active access.
-- A Conditional Access policy exists but is report-only, excluded, or does not apply to the tested principal/application.
-- An app registration is confused with its service principal in another tenant.
-- A managed identity is present but the tester cannot control its host or obtain a token in the relevant context.
-- An expired/revoked SAS or credential metadata is reported as usable access.
-- ARM access is assumed to grant service data-plane access automatically.
-
-## Tooling
-
-### Azure CLI and Microsoft Graph
-
-Use the official Azure CLI for resource context and `az rest` for reviewed ARM/Graph queries not exposed cleanly by a command group. Record CLI/API versions and requested permissions. Broad directory inventory often requires Microsoft Graph application permissions and admin consent; absence of results under a weak token is not proof that objects do not exist.
-
-### Prowler (Conditional)
-
-[Prowler](https://github.com/prowler-cloud/prowler) provides maintained Azure configuration/compliance checks. Install a reviewed pinned release in an isolated environment:
-
-```bash
-python -m pip install 'prowler==<reviewed-version>'
-prowler azure --az-cli-auth --subscription-ids <subscription-id>
-```
-
-Other documented modes include service-principal, browser, and managed-identity authentication. Use a dedicated read-only audit principal with only the documented tenant/subscription permissions. Scope subscription IDs explicitly, protect reports as sensitive asset/identity inventories, account for API volume/throttling, and do not enable cloud upload for assessment data unless approved. Prowler findings are configuration leads; trace effective principal/action/resource paths before treating them as exploitable.
-
-## Summary
-
-Azure security is an identity-and-scope graph across Entra and ARM. Test directory roles, Azure RBAC, PIM, Conditional Access, service principals, managed identities, delegated storage access, workload control, and service data planes as one system while preserving the distinction between each control plane.

-### Contextual CVSS
-
-The published score rates the CVE in the abstract. `contextual_cvss_breakdown`
-rates it **here**, in this codebase, and every dependency report must carry
-one. It is the same 8-metric CVSS v3.1 object as a
-normal finding's `cvss_breakdown` (`attack_vector`, `attack_complexity`,
-`privileges_required`, `user_interaction`, `scope`, `confidentiality`,
-`integrity`, `availability`). You never pass a score: the contextual score and
-vector are computed from the breakdown, and when you provide one it determines
-the finding's severity. `advisory_cvss` stays the published reference.
-
-Start from the advisory's own published metrics and change only what your
-evidence proves is different in this codebase:
-
-- `attack_vector` `N`/`A`/`L`/`P` — as deployed. A library reached only by a
-  local CLI is `L`, not `N`.
-- `attack_complexity` `L`/`H` — raise to `H` when the vulnerable path needs a
-  precondition the code enforces (input validation, a non-default flag, an
-  internal-only route).
-- `privileges_required` `N`/`L`/`H`, `user_interaction` `N`/`R` — what this
-  deployment requires before the path is reachable.
-- `scope` `U`/`C` — whether exploitation here escapes the component boundary.
-- `confidentiality`/`integrity`/`availability` `N`/`L`/`H` — the impact in this
-  codebase. `not_imported` code the build still ships is usually `N` across all
-  three.
-
-Ground every metric in the **source-to-sink trace** from the usage analysis
-(step 3 above), not in a general impression of the package. Derive the metrics
-from that chain: `attack_vector`, `privileges_required`, and `user_interaction`
-come from what the source requires; `attack_complexity` comes from the
-preconditions the hops enforce; `confidentiality`, `integrity`, and
-`availability` come from the data and privileges available at the sink.
-
-When you have no source-to-sink trace, still rate the finding: copy the
-published metrics, change only the metrics the usage level itself proves, and
-say so in the reasoning. For example, for a `not_imported` package that the
-build still ships, keep the published metrics and lower `confidentiality`,
-`integrity`, and `availability` to `N`, because no code path reaches the
-vulnerable symbol. Never invent a hop you did not read.
-
-`contextual_cvss_reasoning` is required with the breakdown. Write two to four
-sentences that another engineer can check without opening the repository. Name
-the chain hop by hop as `entry point -> intermediate call -> package call`, with
-a repository-relative `file:line` for each hop, say who controls the input, and
-say what the contextual rating changes. Example: lowering `attack_vector` to
-`L` and `confidentiality` to `L` with "The only caller of `yaml.load` is
-`parse_manifest` in `scripts/import.py:88`, which `cli/commands.py:212` invokes
-for an operator-supplied path behind the `--allow-unsafe-import` flag that
-`deploy/prod.yaml` never sets. No HTTP route reaches that function, so an
-attacker must already hold shell access on the job host, and the parsed data is
-build metadata rather than customer records."
-
-When the published rating already fits this codebase, repeat the published
-metrics in the breakdown and say in the reasoning that the deployment matches
-the advisory. A contextual rating is a claim you must be able to defend, and it
-never replaces `advisory_cvss` as the published reference.

-description: Test package and executable identity confusion in npx, npm exec, and bunx fallback, plus explicit auto-fetch runners such as pnpm/yarn dlx and deno run npm:, with runner-specific resolution analysis, registry-state controls, reporting gates, and false-positive elimination
----
-
-# npx Confusion
-
-Use this skill when a package runner may execute code from a package other than the publisher or package the workflow intended. For `npx`, `npm exec`, and `bunx`, the recurring case is a missing local executable being reinterpreted as a remotely fetched package spec. Explicit auto-fetch runners such as `pnpm dlx`, `yarn dlx`, and `deno run npm:` have different semantics; analyze them as an adjacent package-identity problem rather than pretending they share npm's fallback order.
-
-Load `dependency_cve_scanning` for known vulnerable versions, `infrastructure_lifecycle` for abandoned domains or registry resources, `agentic_system_security` for the authority of an MCP/agent process, and `semantic_confusion` for the general lookup-order model.
-
-## Core Condition
-
-Choose the branch that matches the runner.
-
-For local-first fallback (`npx`, `npm exec`, or `bunx`), require all of the following:
-
-1. A target-controlled workflow invokes a bare executable or ambiguous package token.
-2. The intended package and its executable name differ, or other evidence establishes the expected publisher/package.
-3. The executable is not resolved in the workflow's real local, workspace, global, or cache context as applicable to that runner.
-4. The runner consequently selects an unintended remote package spec from its configured registry.
-5. The affected workflow reaches that package's executable with security-relevant authority.
-
-For explicit auto-fetch runners (`pnpm dlx`/`pnx`/`pnpx`, `yarn dlx`, or `deno run npm:`), do not require or claim a missing-local-binary fallback. Require evidence that the command names or infers a package different from the one the workflow intended, such as a scoped-package/bin mismatch, typo, generated configuration error, or wrong publisher. Then prove the exact fetched package, chosen binary/module, execution path, and inherited authority.
-
-A public package merely being outside the target's ownership is not a vulnerability. Third-party packages are normal; the mismatch between intended executable provenance and actual registry resolution is the finding.
-
-## Resolution Model
-
-Record the npm version because `npx` has used `npm exec` since npm 7 and resolver behavior changes between releases. For npm, model these decisions:
-
-```text
-bare command
-  -> executable in ancestor node_modules/.bin?
-  -> executable in global bin?
-  -> matching local/global package and usable bin?
-  -> matching environment in the npx cache?
-  -> treat the command token as a package spec
-  -> fetch its manifest from the configured registry
-  -> infer one executable from package.json#bin
-  -> install into the npx cache and execute
-```
-
-Also record:
-
-- working directory and workspace root
-- local dependency tree and generated `node_modules/.bin` links
-- global prefix/bin directory and npx cache
-- `registry`, scope-specific registry rules, proxy and authentication configuration
-- command form, flags, package spec/version, TTY/CI state, and `yes` policy
-- npm's executable-inference result when the package exposes zero, one, or several `bin` entries
-
-Do not collapse package-name lookup and bin selection into one step. npm can fetch a manifest yet fail because it cannot infer exactly one executable.
-
-### Runner distinctions
-
-Record the exact runner and version. Do not reuse npm's local/global/cache ordering for another implementation.
-
-| Runner | Resolution behavior to model | Package binding / fetch control |
-|---|---|---|
-| `npx` / `npm exec` | Local/workspace/global/cache resolution followed by package-spec fallback; executable inference depends on `package.json#bin` | `--package <pkg>` binds the provider; `--no` rejects an install prompt |
-| `bunx` | Checks a locally installed package, then can install from npm into Bun's cache | `--package <pkg>` binds the provider; `--no-install` forbids installation |
-| `yarn dlx` | Downloads the command-named package into a temporary environment by default; this is not a local-bin fallback | `--package <pkg>` selects a different provider package |
-| `pnpm dlx` / `pnx` / `pnpx` | Fetches and hotloads a registry package, then runs its default binary; project trust policies are version-dependent | `--package=<pkg>` selects the provider; prefer declared dependencies plus `pnpm exec` when remote fetch is unintended |
-| `deno run npm:<pkg>` | Uses an explicit npm package spec and cache; a subpath can select a binary | Pin the package/subpath and model lock, cache, lifecycle-script, and Deno permission settings |
-
-Treat mutable tags and ranges such as `latest`, `next`, `@2`, caret, and tilde ranges as selectors, not pins. A privileged repeatable workflow needs an exact reviewed version plus lockfile/integrity enforcement where the runner supports it.
-
-## High-Signal Patterns
-
-### Bare executable fallback
-
-```text
-npx internal-tool
-npx -y internal-tool
-npm exec -- internal-tool
-```
-
-The signal is strongest in CI, release scripts, bootstrap commands, developer setup, and tool/agent configuration where the same command is run repeatedly.
-
-### Scoped package versus unscoped bin
-
-A scoped package can expose an unscoped executable:
-
-```json
-{
-  "name": "@org/tooling",
-  "bin": { "org-tool": "./bin/run.js" }
-}
-```
-
-Inside a correctly installed workspace, `npx org-tool` may resolve `node_modules/.bin/org-tool`. Outside that tree, the same command can fall back to the public package named `org-tool`. Treat documentation, MCP configuration, and bootstrap scripts as separate execution contexts rather than assuming the repository-local result applies everywhere.
-
-### Agent and MCP launchers
-
-Inspect `.mcp.json`, editor/desktop agent configuration, devcontainers, and generated tool launchers for `command: npx` plus `-y` and a bare package or binary name. Combine this resolver analysis with `agentic_system_security` to determine the credentials, tools, files, and network access inherited by that process.
-
-## Candidate Collection
-
-Search executable surfaces and retain file, line, command, and execution context:
-
-```bash
-rg -n --no-heading -g '!node_modules' -g '!**/dist/**' \
-  -e '\b(npx|npm\s+exec|bunx|pnx|pnpx|pnpm\s+dlx|yarn\s+dlx)\s+[^[:space:]]+' \
-  -e '\bdeno\s+run\b[^\n]*\bnpm:' \
-  -e '"command"\s*:\s*"(npx|bunx|pnx|pnpx|pnpm|yarn|deno)"' \
-  -e '"args"\s*:\s*\[[^]]*"(dlx|npm:[^"]+|-y)"' \
-  .
-```
-
-Search the source/configuration tree rather than a fixed file list: these commands also live in
-`scripts/`, husky/lint-staged hooks, `turbo.json`/`nx.json` task definitions,
-`.circleci/`, composite-action `action.yml`, devcontainer `postCreateCommand`,
-nested workspace `package.json` files, and editor/agent config under
-`.cursor/`, `.vscode/`, and `.mcp.json`. If generated output is itself shipped or executed, search its specific directory separately instead of globally including every `dist/` artifact.
-
-Also inspect:
-
-- package scripts and lifecycle hooks
-- workspace package `name` and `bin` maps
-- READMEs and generated setup instructions
-- CI composite actions and reusable workflows
-- source maps or bundled package metadata that reveal internal commands
-
-Discard paths, shell variables, flags, Node built-ins, and text that is not executed or presented as an executable command.
-
-## Establish the Actual Resolution
-
-Prefer inspecting the existing dependency tree, lockfile, workspace packages, and `.bin` links. Do not run `npm ci` merely to decide whether a command is local: it changes the tree and can execute lifecycle scripts.
-
-For a version-controlled reproduction environment, record npm's registry lookup without allowing a missing package to be installed:
-
-```bash
-npx --no --loglevel=http <candidate>
-```
-
-Interpret this carefully:
-
-- a local executable may run immediately; `--no` only refuses missing-package installation
-- an HTTP registry request shows fallback, not ownership or successful execution
-- a cancellation naming the missing package shows npm's chosen package spec
-- cache, global installs, parent directories, workspaces, and registry configuration can change the result
-
-Repeat the resolution analysis in every context that matters: repository root, documented launch directory, CI checkout, generated agent configuration, and bootstrap-before-install flow. Do not substitute a clean empty directory for the target context except to understand npm's generic name mapping.
-
-Do not apply `npx --no` as a generic dry-run flag. Use `bunx --no-install` only for Bun's local-resolution question. `dlx` and `deno run npm:` already name a remotely resolvable package, so validate their package spec, registry, cache/lock, selected binary or subpath, and permissions using that runner's own behavior.
-
-## Ownership and Registry State
-
-Query the exact registry selected by the target configuration, then distinguish:
-
-- intended package owned by the expected publisher
-- unrelated public package with the same name
-- unregistered name (`404` from a functioning registry)
-- private or access-controlled name (`401`/`403`)
-- transient/rate-limited/blocked lookup (`429`, `5xx`, timeout)
-- placeholder, reserved, disputed, or previously unpublished name
-
-Before trusting any of those states, check whether the target's lookup path can distinguish a known existing package from a newly generated negative control. Resolve the registry from the same working directory and configuration used by the target:
-
-```bash
-# Public npm example; use a known package from the actual registry when different.
-task_registry="$(npm config get registry)"
-npm view --registry="$task_registry" lodash name --json
-npm view --registry="$task_registry" "$(openssl rand -hex 12)" name --json
-```
-
-Run the pair through the same `.npmrc`, scope routing, authentication, proxy, and egress path as the candidate. Direct `curl` requests to the public registry are a separate observation unless the target runner uses that exact route. A successful pair establishes coarse positive/negative discrimination, not authenticity of every candidate response; verify that returned documents name the requested package and contain plausible registry metadata.
-
-If the pair fails or returns indistinguishable responses, mark the target-path registry state `UNKNOWN`. An independently verified public-registry response may characterize public state, but it does not prove what the target runner resolves. Re-confirm candidate absence before relying on it.
-
-A `404` proves absence from that registry at that time; it does not by itself prove that registration would be accepted. Registry similarity, trademark, reservation, security-hold, and unpublish rules remain separate facts. Two concrete cases to check rather than infer:
-
-- A registry-owned security placeholder occupies the name even when its only version is `0.0.1-security`. Do not identify one from the version alone: inspect the packument, description, dist-tags, top-level and version-level maintainers, and version publisher such as `_npmUser`.
-- npm rejects new unscoped names that collide with an existing package after `.`, `-`, and `_` are removed. Normalize both the candidate and existing names: looking up only the candidate's stripped form catches `some-tool` versus `sometool`, but misses the reverse direction when the existing package contains punctuation. Treat this as registry-policy eligibility evidence, not a guarantee that registration would otherwise succeed.
-
-When a candidate name is already registered, distinguish the target's own
-organization from an unrelated party before calling it a clash. Correlate `npm owner ls <name>`, version-level publisher metadata, known target-controlled npm organizations, and independently verified repository provenance. Repository/homepage fields are self-asserted supporting evidence and do not settle ownership alone. If publisher identity remains ambiguous, mark it `UNKNOWN`.
-
-## Validation and Impact
-
-Demonstrate the complete resolver statement:
-
-```text
-target-controlled invocation and context
-  -> intended executable absent
-  -> exact public package spec selected
-  -> package ownership/availability state
-  -> execution trigger and inherited authority
-```
-
-Do not report an unregistered name without an execution path, or an execution path whose command is satisfied locally in every relevant context. Derive impact from the environment that executes the package: developer workstation, CI job, release pipeline, agent runtime, container build, or documentation-only workflow.
-
-## Reporting
-
-There is no CVE and no vulnerable installed version here, so this does not go through `create_dependency_report`; that tool requires an advisory-matched CVE. Use `create_vulnerability_report` only after the applicable core condition is fully verified.
-
-A registry lookup or `404` alone is candidate evidence, not a working PoC. The report must preserve the target invocation and execution context, show the exact selected package and binary/module, demonstrate the runner's execution transition in a representative controlled setup without publishing the contested name, and establish the authority inherited by that process. When source is available, include the responsible invocation/configuration and concrete fix in `code_locations`.
-
-Do not file documentation/comment-only references, locally satisfied commands, unregisterable names, ambiguous ownership, or chains that stop before package execution. Retain them as investigation notes only when useful.
-
-Derive CVSS from the demonstrated path rather than a fixed severity label. Account for required developer/user action, registry and configuration prerequisites, runner permissions, credential availability, and the confidentiality, integrity, and availability actually exposed. A CI, release, container-build, or agent context can be severe, but the context name alone does not establish High or Critical impact.
-
-Deduplicate by root cause, affected asset/workflow, and remediation. Combine call sites when the same configuration mistake and fix apply; keep separate findings when the same candidate name affects different products, tenants, runner semantics, authority, or fixes.
-
-## False Positives
-
-- The executable is provided by a declared dependency in every real execution context.
-- `npx --package @scope/pkg <bin>` explicitly binds the executable to the intended package.
-- A versioned package spec or scope-specific registry points to the intended publisher.
-- The public package is the deliberately selected third-party tool.
-- npm fetches the manifest but cannot infer or execute a bin.
-- The reference appears only in generated/minified text with no executable call site.
-- A registry/proxy error is misread as an unregistered name, or the target-path control pair is inconclusive.
-- A package is absent but registry policy prevents the contested registration.
-- The command resolves to the deliberately selected ecosystem tool and expected publisher.
-- The already-registered name belongs to the target's own organization.
-- An explicit `dlx` or `npm:` package spec is treated as missing-local fallback without evidence of a package/publisher mismatch.
-
-## Remediation
-
-- Install the intended package and invoke its local executable through an npm script.
-- For npm, bind and pin the provider: `npx --package @org/tool@<version> org-tool`; use `--no` when a missing dependency must fail.
-- For Bun, use `bunx --package @org/tool@<version> org-tool` and `--no-install` when remote installation is not intended.
-- Replace `yarn dlx`/`pnpm dlx` in repeatable or privileged workflows with a declared, locked dependency plus the runner's local `exec` command. When ephemeral execution is required, bind and pin the provider package explicitly.
-- For Deno, pin the `npm:` package and binary subpath, retain a reviewed lockfile, use cache-only operation where appropriate, and grant only the permissions the command requires.
-- Route private scopes to the intended registry and prevent public fallback.
-- Pin package versions and lockfiles in privileged workflows.
-- Replace bare `npx -y <name>` agent launchers with reviewed, publisher-qualified, version-pinned package specs.
-
-## Summary
-
-Treat package-runner confusion as an identity and execution-context bug. Prove the runner-specific transition, distinguish binary names from package names, verify registry and publisher state without equating absence with eligibility, and report only a complete execution path under the affected workflow's actual authority.

-- scoped/private package names exposing unscoped binary or alias names

----
-
-# Infrastructure Lifecycle Trust
-
-Use this skill when a product, application, device, image, or organization continues to trust an external name or provider resource whose ownership can expire, be deleted, be reassigned, or move outside the intended organization.
-
-This is broader than subdomain takeover. The vulnerable asset may make outbound requests to a retired update bucket, load JavaScript from an abandoned domain, send mail to an expired MX domain, query a reassigned WHOIS/RDAP server, install from a missing package namespace, or beacon to an embedded telemetry/control endpoint. The security property is continuity of ownership across the full lifetime of every trust consumer.
-
-## Trust-Consumer Graph
-
-Model each dependency:
-
-```text
-consumer/version/deployment
-  -> embedded logical name or URL
-  -> DNS/provider/package resolution chain
-  -> current owner/controller
-  -> content/protocol accepted
-  -> privilege and trigger in the consumer
-```
-
-Record separately:
-
-- where the reference is stored: source, binary, firmware, image layer, config, database, IaC, documentation, update metadata
-- deployed versions and whether the consumer still runs
-- endpoint type, resolution chain, TLS/signature/authentication requirements, and fallback order
-- current registration/provider ownership and historical ownership
-- request trigger, frequency, payload/data sent, and response/content interpretation
-- consumer privilege: browser origin, installer/root, CI runner, mail receiver, parser, agent, or telemetry process
-- decommission owner, renewal/update process, and monitoring coverage
-
-A domain or bucket being available is only half the finding. Show that a live in-scope consumer still trusts it and what that consumer would accept.
-
-## Control and Claimability Levels
-
-Do not collapse these into one claim:
-
-| Level | Evidence |
-|---|---|
-| Indicator | NXDOMAIN, expired registration, provider tombstone, missing package/resource |
-| Authoritative availability | Registrar/provider/package authority confirms the exact name/resource can be acquired or bound |
-| Acquisition/control | Authorized tester controls the registrable domain, resource, namespace, or provider binding |
-| Protocol identity | Required DNS, custom-host binding, TLS certificate, authentication, or protocol handshake succeeds |
-| Consumer acceptance | A live in-scope consumer contacts the controlled endpoint and accepts the relevant response semantics |
-
-Record the highest proven level for every consumer. Before acquisition or provider binding, determine whether control can immediately receive existing third-party traffic and apply the Passive Sensor and Sinkhole plan below.
-
-## High-Value Dependency Classes
-
-### Update and Code Distribution
-
-- firmware/software update URLs, manifests, package indexes, installers, drivers, VM/container images
-- CDN/object-storage buckets serving binaries, scripts, templates, rules, signatures, or configuration
-- browser JavaScript/CSS imports and desktop/mobile auto-update channels
-- bootstrap, CI, devcontainer, build, and installation scripts
-- model/agent skill, plugin, prompt, MCP server, and tool-definition update channels
-
-Record signature, hash, certificate, pinning, version/rollback, and content-type enforcement. TLS alone authenticates the current domain controller, not continuity with the original publisher.
-
-### Naming and Package Resolution
-
-- missing public/private package names, scoped package versus executable alias, plugin/module/template namespaces
-- `PATH`, autoload, search path, registry, cache, mirror, and remote fallback order
-- provider-generated hostnames or globally unique resource names released on deletion
-- legacy aliases retained in manifests, lockfiles, scripts, or installed products
-
-Do not register or publish candidate names merely to test them without explicit authorization and a containment plan. Prove the consumer's resolution behavior first.
-
-Registry "missing" responses are not interchangeable with "claimable".
-Similarity, reservation, security-hold, dispute, and unpublish rules can block
-a name that returns `404`; verify ownership and registry policy separately.
-Load `npx_confusion` when the consumer first treats a missing executable as an
-npm package spec. Model other ecosystems independently rather than assuming
-npm's resolution order applies to them.
-
-### Mail and Identity
-
-- expired organizational, supplier, recovery, notification, or former employee domains
-- MX targets and catch-all aliases that remain in applications, address books, SSO, password recovery, certificates, or vendor accounts
-- OAuth redirect/logout URIs, SAML endpoints, webhook callbacks, CORS/CSP allowlists, and trusted-origin lists tied to retired hosts
-- domain-based tenant verification and support/administrative identity flows
-
-Differentiate ability to receive a tester-created message from interception of real correspondence. Do not access unrelated mail or use received secrets/credentials.
-
-### Telemetry, Control, and Protocol Infrastructure
-
-- crash reporting, analytics, licensing, activation, NTP/DNS, support, and health-check endpoints
-- hardcoded agent/controller, webshell/C2, webhook, exfiltration, or callback domains embedded in deployed systems
-- hardcoded retired WHOIS/RDAP endpoints, certificate validation services, keyservers, mirrors, proxies, and service-discovery dependencies
-- local/remote management domains in appliances, mobile apps, extensions, and container images
-
-Treat unexpected inbound traffic as potentially sensitive. Passive receipt does not authorize interaction, command issuance, credential use, or expansion beyond the approved sensor purpose.
-
-## Discovery
-
-### Source, Image, and Firmware Corpus
-
-Extract hostnames, URLs, email domains, bucket names, package names, registry endpoints, and certificate subjects from:
-
-- source and history, lockfiles, CI/IaC, release assets, SBOMs
-- container/VM layers including deleted-file history
-- firmware rootfs, strings/resources, scripts, configs, examples, and updater logic
-- JavaScript/mobile/desktop bundles, extensions, templates, and documentation
-- logs and network captures from controlled normal operation
-
-Use staged extraction rather than relying on one broad regex:
-
-```bash
-# URLs and email addresses
-rg -n -i 'https?://|wss?://|s3[.-]|blob\.core\.|[A-Z0-9._%+-]+@[A-Z0-9.-]+' extracted/
-
-# Then query format-aware config keys, DNS/MX data, certificate metadata,
-# package manifests, and binary strings for bare hostnames/namespaces.
-```
-
-Review bare-hostname candidates for prose, source-map, test, and generated-data false positives. Deduplicate content-addressed layers and repeated vendor boilerplate so prevalence is not inflated. Preserve the source file, artifact hash, version, and surrounding semantic context for every candidate.
-
-### Ownership and Resolution History
-
-- Resolve A/AAAA/CNAME/NS/MX/TXT/CAA and retain complete chains.
-- Check current registrar/provider resource state through authoritative sources, including custom-domain binding and reservation rules.
-- Use historical DNS, CT, WHOIS/RDAP, package metadata, source history, and release timelines to establish ownership drift.
-- Identify wildcard/catch-all responses, parked domains, provider tombstones, and reused cloud IPs that mimic availability.
-- Compare vulnerable/current builds to learn whether the reference was removed, replaced, or cryptographically hardened. Record CAA, DNSSEC/DANE where relevant, certificate issuance/custom-host requirements, pinning, embedded trust stores, and independent content signatures.
-
-Do not rely on an HTTP `404`, NXDOMAIN, or “NoSuchBucket” alone. Providers reserve names, enforce ownership verification, or return identical errors for owned/private resources.
-
-### Live Consumer Confirmation
-
-Within scope, observe a controlled consumer through:
-
-- offline code/dataflow from trigger to request and response consumer
-- DNS/HTTP proxy logs in a lab
-- packet capture or process/network tracing during a normal test operation
-- a tester-owned canary endpoint configured through a supported setting
-- already-authorized sensor/sinkhole telemetry
-
-Record request method/protocol, SNI/Host, headers, authentication, body data classification, retry cadence, TLS verification, and how the response is parsed or executed.
-
-## Security Analysis
-
-Ask in order:
-
-1. Can ownership/control actually transfer to an unrelated party?
-2. Does an in-scope deployed consumer still resolve or contact it?
-3. What authenticity/integrity checks survive endpoint takeover?
-4. What response fields/content/protocol messages can the controller influence?
-5. Under what identity and privilege does the consumer process them?
-6. Is the trigger automatic, scheduled, administrative, user-driven, or update-only?
-7. What population and versions remain affected?
-8. What claimability level is proven, and is acquisition necessary for the remaining questions?
-9. Could acquisition receive out-of-scope traffic or data?
-10. Does this name serve several distinct consumers that require separate semantics and impact analysis?
-
-High-impact patterns include:
-
-- unsigned or weakly verified update/package content processed with system/administrator privilege
-- JavaScript loaded under a trusted web origin or CSP allowlist
-- mail/recovery/identity messages delivered to a re-registered domain
-- secrets or device metadata automatically sent to a reassigned endpoint
-- trusted control/telemetry responses parsed as commands, config, templates, or executable content
-- CA/domain verification, service discovery, or protocol logic depending on mutable external ownership
-
-## Passive Sensor and Sinkhole Handling
-
-Operating a domain or provider resource that receives real third-party traffic is a separate data-handling activity, not ordinary proof-of-concept hosting. Before enabling it, define:
-
-- written authorization and legal/privacy owner
-- accepted protocols and non-interaction policy
-- collection minimization, encryption, access control, retention, deletion, and redaction
-- handling for credentials, personal data, malware, or out-of-scope victims
-- notification/escalation and provider/registrar coordination
-- prohibition on commands, authentication attempts, payload delivery, or use of received secrets
-
-Prefer aggregate metadata or a unique tester-controlled canary. Do not deliberately expose a genuinely vulnerable product to collect wild exploitation without separate deployment authorization and containment review.
-
-## Relationship to Other Skills
-
-- Load `subdomain_takeover` for dangling DNS records or custom-domain provider bindings. Ordinary expiration/re-registration of a registrable domain, MX identity, or embedded software endpoint remains in this skill.
-- Load `source_aware_sast` for targeted source/dataflow confirmation; string presence does not prove current ownership or live consumption.
-- Load `agentic_system_security` only when the endpoint supplies or controls AI skills, plugins, MCP/model adapters, tool definitions, or effective agent authority.
-- Load `semantic_confusion` only when a security decision and privileged consumer use different endpoint/package/alias representations or resolution results. Pure temporal ownership drift does not require it.
-
-## Validation Deliverable
-
-Include:
-
-1. exact consumer artifact/version/deployment and reference location
-2. full DNS/provider/package resolution and current ownership evidence
-3. historical ownership/decommission timeline
-4. live or source-confirmed request trigger and accepted response semantics
-5. TLS/signature/hash/authentication behavior
-6. consumer privilege, affected population, and configuration prerequisites
-7. controlled ownership/canary evidence where authorized
-8. highest claimability level and confidence in live-consumer/prevalence evidence
-9. sensor/data-handling authorization when acquisition could receive existing traffic
-10. separate impact analysis for each mail, identity, update, telemetry, code, or control consumer
-11. remediation across both the endpoint and every retained consumer
-
-## Common False Positives
-
-- NXDOMAIN/provider tombstone with a name that cannot be registered or bound.
-- A hardcoded URL present only in dead code, examples, tests, or an undeployed version.
-- Live requests go to a vendor-controlled wildcard/catch-all despite an apparently missing specific resource.
-- Update content is independently signed and the reassigned endpoint cannot produce an accepted artifact; this usually blocks forged-code impact, but metadata exposure, update suppression, unsigned manifest fields, and rollback/version behavior still require analysis.
-- Expired domain appears in documentation but is absent from authentication, mail, software, and deployed configuration.
-- A package name is unregistered but the consumer is pinned to a private registry with no public fallback, the scope is routed by `.npmrc`, or the command is already satisfied by a locally installed binary.
-- The name is unregistered but registry policy, reservation, dispute, or unpublish state prevents the contested registration.
-- Inbound sensor traffic cannot be attributed to an in-scope consumer/version.
-
-## Remediation
-
-- Remove or replace references in every supported and still-deployed version.
-- Retain defensive ownership of externally embedded domains/resource names for the consumer's realistic lifetime.
-- Sign update/config/package content with independently managed, rotatable keys and enforce rollback/version policy.
-- Eliminate implicit public fallback; pin registries, publishers, hashes, and plugin identities.
-- Inventory domain/MX/provider/package dependencies in decommission workflows and continuous monitoring.
-- Revoke old credentials/tokens, rotate trust, and provide a migration/kill-switch path for stranded clients.
-- Monitor DNS, CT, registrar, provider binding, package namespace, and live outbound traffic for ownership drift.
-
-## Summary
-
-External names are long-lived security dependencies. Track every consumer to its current controller, prove that deployed software still trusts the endpoint, analyze the authenticity checks and processing privilege, and manage ownership for as long as any supported or abandoned client can call home.

-# LLM Application Security
-
-Use this as the umbrella workflow for the [OWASP Top 10 for LLM Applications 2026](https://genai.owasp.org/resource/owasp-genai-llm-top-10-2026/). Load `llm_prompt_injection` for deeper LLM01 testing and the relevant conventional vulnerability skill when an LLM-controlled value reaches a browser, query, command, URL, file, or authorization sink.
-
-Treat the identifiers as a coverage taxonomy, not as report titles. Classify a finding by its technical root cause and affected trust boundary. One exploit chain may contain several OWASP categories, while one root cause should not become ten duplicate reports.
-
-The LLM list covers the model as a component of an application. When a model acts through tools, persistent memory, peer agents, or autonomous workflows, apply this list and pair the assessment with the OWASP Top 10 for Agentic Applications 2026; do not force every agentic failure into an LLM category.
-
-## Architecture and Evidence Map
-
-Map the complete system before testing prompts:
-
-```text
-users / tenants / external content
-  -> API, UI, file and multimodal ingestion
-  -> prompt builder, policy and orchestration
-  -> model/provider and context window
-  -> memory, cache, RAG retrieval and vector index
-  -> tools, MCP servers, plugins and peer agents
-  -> output parsers, renderers and downstream systems
-  -> logs, traces, feedback, evaluation and training pipelines
-```
-
-For every edge, record:
-
-- **Data authority:** who creates, reads, updates, deletes, approves, and owns the data; tenant and sensitivity; retention and training use.
-- **Action authority:** caller identity, downstream identity, permissions, authorization checks, confirmation, transaction boundaries, and audit evidence.
-- **Transformation:** serialization, chunking, embedding, retrieval, reranking, prompt placement, output parsing, and cache keys.
-- **Runtime identity:** application build, provider, model and revision, prompt revision, tool set, feature flags, corpus/index snapshot, temperature/seed where available, and quota policy.
-
-Do not treat the model as an authorization principal or a trusted parser. Put deterministic authentication, authorization, validation, and policy enforcement outside the model.
-
-## 2026 Coverage Matrix
-
-| OWASP 2026 risk | Security invariant to test | Primary route |
-|---|---|---|
-| LLM01:2026 Prompt Injection | Untrusted instructions cannot cross a meaningful policy or authority boundary | `llm_prompt_injection` |
-| LLM02:2026 Sensitive Information Disclosure | A response, context, cache, trace, training path, or retrieval result reveals only data authorized for the caller | This skill + `information_disclosure` |
-| LLM03:2026 Excessive Agency | Tools expose only required functionality, permissions, and autonomy, with complete mediation at the action | This skill + `broken_function_level_authorization` / `business_logic` |
-| LLM04:2026 Supply Chain | Every model, adapter, dataset, tokenizer, prompt, plugin, package, image, and hosted API has verified provenance and an immutable deployment identity | This skill + `dependency_cve_scanning` / `source_aware_sast` |
-| LLM05:2026 Data and Model Poisoning | Attacker-influenced training, tuning, feedback, memory, or embedding data cannot persistently alter protected behavior unnoticed | This skill |
-| LLM06:2026 Unbounded Consumption | Every request, recursive action, queue, and billable operation has enforceable cumulative resource and cost bounds | This skill + `business_logic` / `race_conditions` |
-| LLM07:2026 Misinformation | Unsupported output cannot silently drive a security-sensitive or high-impact decision | This skill + `business_logic` |
-| LLM08:2026 Hidden Context Exposure | Hidden instructions and operational context contain no secrets and reveal no security-relevant logic or capability that materially increases attacker power | This skill + `llm_prompt_injection` / `information_disclosure` |
-| LLM09:2026 Vector and Embedding Weaknesses | Ingestion and retrieval preserve tenant, source, document authorization, and embedding confidentiality across the index lifecycle | This skill + `idor` / `information_disclosure` |
-| LLM10:2026 Improper Output Handling | Model output remains untrusted until the actual downstream grammar and sink validate it | This skill + the sink-specific vulnerability skill |
-
-## Assessment Workflow
-
-1. Inventory every LLM-backed feature, model endpoint, ingestion route, retrieval source, tool, output consumer, and feedback/training path.
-2. Build the data-and-authority map above for each user role and tenant.
-3. Create a test matrix across application build, model/revision, prompt revision, tool configuration, identity, corpus snapshot, and quota tier.
-4. Use controlled records with distinct per-user and per-tenant markers to distinguish context, retrieval, cache, memory, and training leakage.
-5. Establish a normal baseline and matched negative control before adversarial variants. Run repeated trials and report success counts because model behavior is stochastic.
-6. Validate the application-side effect, retrieved record, rendered sink, downstream authorization result, resource meter, or persistent model change. Model narration alone is not evidence of that effect.
-7. Label each claim **architecture-confirmed**, **dynamically verified**, **candidate**, or **disproven**. Do not turn an unsafe architecture property into a claimed exploit, or ignore a confirmed control defect merely because downstream impact has not yet been exercised.
-8. Report the smallest technical root cause that explains the demonstrated impact, then document related OWASP categories as chain context.
-
-## Source Review
-
-Trace source to sink around:
-
-- provider SDK calls, local inference servers, model gateways, and fallback providers
-- system/developer prompts, templates, message-role conversion, context truncation, reasoning channels, and prompt caches
-- file, URL, email, image/audio/video, connector, tool-result, peer-agent, and memory ingestion
-- embedding generation, collection/namespace selection, metadata filters, reranking, hybrid search, and retrieval caches
-- function/tool definitions, MCP clients/servers, generic HTTP/shell/SQL tools, peer-agent delegation, and approval handlers
-- model output parsers, HTML/Markdown renderers, terminals/IDEs/logs, code execution, query builders, URLs, file paths, templates, and policy decisions
-- training/fine-tuning jobs, adapters, datasets, feedback stores, evaluation corpora, model registries, and runtime downloads
-- token accounting, request limits, concurrency, retries, agent-loop depth, fan-out, async queues, streaming cancellation, and provider billing
-
-Record both forward and reverse reachability: attacker-controlled input to privileged consumer, and privileged consumer back to every input or model output that can influence it.
-
-## Optional Tool Routing
-
-Use tools only when they match the deployed surface. Treat generated cases and scanner labels as leads until the application-side boundary is validated.
-
-- **[Promptfoo](https://github.com/promptfoo/promptfoo)** — use for repeatable model/application trials, custom adversarial cases, graders, provider comparisons, and success-rate regression. Install the reviewed version locally with `npm install --save-dev --save-exact promptfoo@0.122.0`, then invoke `./node_modules/.bin/promptfoo redteam run`. Define explicit plugins, assertions, `numTests`, `maxConcurrency`, and `delay`; provider calls may transmit test data and incur cost. Its `owasp:llm` preset still uses the 2025 category mapping in version 0.122.0, so build or select tests from the 2026 matrix above and do not present the preset report as complete 2026 coverage.
-- **[MCP Inspector](https://github.com/modelcontextprotocol/inspector)** — use for LLM01/LLM03 surface mapping when MCP servers are present. Install the reviewed version with `npm install --save-dev --save-exact @modelcontextprotocol/inspector@2.2.0`, then use `./node_modules/.bin/mcp-inspector --cli --config <reviewed-config> --server <name> --method tools/list` and the equivalent `resources/list` / `prompts/list` operations. Starting a stdio server executes that configured process, initialization/list handlers may have side effects, and `tools/call` can perform the real action; inspect the target and credentials before invoking it.
-- **[ModelScan](https://github.com/protectai/modelscan)** — use for LLM04 static triage of supported H5, Pickle, and SavedModel artifacts before loading them, for example `uvx modelscan==0.8.8 -p <artifact>`. Run it as an untrusted-file parser in an isolated analysis environment. A clean result covers only the scanner's supported formats and signatures; it does not establish artifact provenance, integrity, or absence of behavioral backdoors.
-
-## LLM01:2026 Prompt Injection
-
-Load `llm_prompt_injection` and test direct, indirect, stored, cross-modal, tool-result, memory, intermediate-reasoning, and multi-turn instruction paths. Include content from web pages, documents, messages, metadata, OCR, images/audio/video, retrieved chunks, tools, MCP servers, and peer agents.
-
-For each delivery path, record provenance as untrusted, semi-trusted, or trusted-by-the-operator but attacker-writable through another workflow. Test plain, split, multilingual, encoded, invisible-Unicode, and multimodal representations where the deployed preprocessing makes them relevant.
-
-Define the violated invariant before testing: unauthorized data access, an unauthorized action, corruption of a protected decision, persistent behavior change, or unsafe downstream output. A jailbreak or changed tone without a security-relevant boundary is not automatically an application vulnerability.
-
-Distinguish:
-
-- **Prompt injection:** input changes model behavior contrary to application policy.
-- **Jailbreak:** model safety behavior is bypassed; application impact depends on the product's requirements and connected capabilities.
-- **Poisoning:** attacker influence persists in training, feedback, memory, or an indexed corpus and affects later users or decisions.
-
-## LLM02:2026 Sensitive Information Disclosure
-
-Inventory sensitive data in prompts, reasoning or scratchpad traces, retrieved chunks, tool results, memory, caches, logs, training/feedback stores, model outputs, and provider retention paths.
-
-Test separately for:
-
-- cross-user and cross-tenant context, memory, cache, and retrieval leakage
-- secrets or private records inserted into prompts, tool schemas/results, errors, traces, or telemetry
-- retained user content later used for training, evaluation, or another user's response
-- training-data membership or memorization when the tested model and data provenance make that claim meaningful
-- model/provider options that expose logits, log probabilities, hidden metadata, raw context, or internal reasoning
-
-Use distinct markers for each principal and storage stage. A fabricated secret or hallucinated record is not disclosure; correlate the output to a real record and its unauthorized source.
-
-## LLM03:2026 Excessive Agency
-
-Create a capability ledger for every tool and peer agent:
-
-```text
-tool -> exposed operations -> downstream identity -> permissions
-     -> caller/user binding -> argument validation -> authorization
-     -> side effects -> retry/idempotency -> audit evidence
-```
-
-Test the three independent causes:
-
-- **Excessive functionality:** unused, generic, administrative, shell, arbitrary-URL, or broad CRUD tools remain callable.
-- **Excessive permissions:** tools use a shared/service identity or scopes broader than the initiating user and requested operation.
-- **Excessive autonomy:** consequential actions execute without human or deterministic authorization appropriate to the exact action, object, arguments, identity, and current state.
-
-Tool descriptions, model instructions, hidden channel names, and confirmation prose are not authorization controls. Enforce authorization again at the tool/downstream system. Test delegation, recursive plans, retries, race/state changes between approval and execution, and whether untrusted tool results become new instructions.
-
-Prove the accepted tool call and downstream result. A model saying it invoked a tool is not evidence that the action occurred.
-
-## LLM04:2026 Supply Chain
-
-Build an inventory beyond ordinary packages:
-
-- base models, weights, tokenizers, configuration, adapters/LoRA, quantizations, and model-conversion outputs
-- training, tuning, evaluation, and embedding datasets
-- prompt/template repositories, skills, plugins, MCP servers, hosted model APIs, and model gateways
-- Python/JavaScript/native dependencies, containers, drivers, accelerators, and serving infrastructure
-
-For each component, record origin, owner, license/terms, exact revision or digest, hash/signature/attestation, review status, update channel, runtime downloads, and effective permissions. Resolve every model alias, branch, mutable tag, adapter, and custom-code dependency to the artifact actually loaded. Identify who can mutate the source, promotion record, cache, or registry and whether the promoted artifact matches its claimed identity.
-
-Inspect model loading as code loading. Pickle-compatible weights, custom model/tokenizer code, conversion hooks, package installation, and remote-code trust options can execute during acquisition or load. Trace the selected loader, artifact format, revision, initialization hooks, and resulting process or file activity.
-
-Trace model-generated dependency names through every package runner, installer, build file, and registry lookup. A fabricated package recommendation is LLM07 misinformation; accepting or auto-installing an unverified name, namespace, or registry artifact is the LLM04 supply-chain boundary. Verify ownership and provenance rather than treating a registry response alone as proof of safety.
-
-Use `dependency_cve_scanning` for verified known-CVE software versions. A malicious or tampered model, dataset, adapter, prompt, or plugin is a different supply-chain finding and requires provenance plus behavioral or loader evidence.
-
-## LLM05:2026 Data and Model Poisoning
-
-Map who can contribute to every pre-training, fine-tuning, preference, feedback, evaluation, memory, and embedding dataset. Record moderation, approval, deduplication, weighting, precedence, versioning, rollback, and the delay before data affects production.
-
-Test:
-
-- targeted trigger/backdoor behavior versus broad quality degradation
-- poisoned examples that survive normalization, deduplication, chunking, or retraining
-- feedback loops where model output or user ratings become future training data
-- shared memory or indexed content that persists across users, sessions, or releases
-- compromised adapters, merged models, or fine-tuning jobs that alter only a narrow topic, identity, or trigger
-
-Compare clean and candidate snapshots with a fixed evaluation corpus and repeated trials. Trace a candidate record into the exact training/index snapshot and demonstrate persistence plus a protected behavior change. One retrieved malicious instruction may be LLM01 rather than proof that the model or dataset was poisoned.
-
-Classify provenance/distribution compromise under LLM04 and durable corruption of data, weights, adapters, templates, or model behavior under LLM05. Record both when one chain crosses both boundaries, but do not duplicate the same root cause.
-
-## LLM06:2026 Unbounded Consumption
-
-Inventory every resource multiplier:
-
-- input and output tokens, context windows, image/audio/video/document processing, embeddings, reranking, and model tier
-- requests per user/key/IP/tenant, concurrency, batch size, and organization-wide budget
-- agent iterations, tool calls, peer-agent fan-out, retries, provider failover, and recursive workflows
-- upload count/size, chunk count, index growth, queued/background jobs, and retained outputs
-- streaming connections, disconnect cancellation, timeouts, cache behavior, and partial failures
-- logprobs or repeated-query surfaces that increase extraction or model-replication risk
-
-Model cumulative work, not isolated limits: depth × fan-out × retries × failovers × model/tool cost. Test limits at request, identity, tenant, and global layers. Confirm that alternate keys, endpoints, models, encodings, streaming, retries, and concurrent requests cannot bypass accounting. Verify cancellation stops upstream inference and tool work, and that failed/retried operations do not bill or enqueue without bounds.
-
-Record measured requests, tokens, tool calls, queue growth, latency, and provider-side cost/usage. Increase load in controlled steps; do not infer denial of service, model extraction, or financial impact from the mere absence of a UI counter.
-
-## LLM07:2026 Misinformation
-
-Define a trusted answer set and the downstream decision before testing. Separate ordinary model fallibility from a security or business-logic flaw.
-
-Exercise:
-
-- absent, ambiguous, stale, and mutually contradictory sources
-- fabricated, mismatched, or forged citations, quotations, evidence, and task-completion claims
-- adversarial sources that rank above authoritative material
-- confidence language and UI cues that overstate certainty
-- generated code, policy, medical/legal/financial guidance, identity matching, fraud/risk decisions, and other outputs consumed without verification
-- automated actions triggered by unsupported claims
-
-Measure claim support, citation coverage and entailment, source authority, abstention, and decision error across a repeatable corpus rather than reporting one hallucinated answer. Report when unsupported output crosses a defined trust boundary or drives a protected decision without required verification; otherwise record it as a quality/reliability issue.
-
-## LLM08:2026 Hidden Context Exposure
-
-Inventory non-user-facing content available to the model: system and developer instructions, retrieved policy text, user-profile context, tool/function schemas, workflow criteria, internal roles, reasoning scaffolds, and operational configuration.
-
-Test extraction, inference, and reconstruction separately. Compare purported hidden context with the deployed revision, a unique marker, or observed capability because models can fabricate plausible prompts and tool lists.
-
-Classify the result by what it exposes:
-
-- embedded credentials, tokens, private records, or connection material -> LLM02 disclosure, with LLM08 as the exposure path
-- hidden rules, trust boundaries, tool schemas, or workflow logic that materially improve an attack -> LLM08
-- authorization, filtering, or privilege controls that depend on hidden-context secrecy or model obedience -> the underlying deterministic-control failure
-- generic instructions with no sensitive content, security reliance, or material attacker advantage -> no standalone vulnerability
-
-Assume hidden context is discoverable. Keep secrets and security-critical decisions outside it, and test the underlying control even when exact prompt wording cannot be recovered.
-
-## LLM09:2026 Vector and Embedding Weaknesses
-
-Map ingestion authorization separately from retrieval authorization. Preserve source identity, tenant, document ACL, classification, retention, and deletion state through chunking, embedding, indexing, replication, reranking, and caching.
-
-Test:
-
-- authorization inside vector search, filtering after top-k but before context construction, and filtering only after the model sees candidates
-- shared collections/namespaces and missing, inconsistent, or fail-open tenant filters
-- metadata-filter injection, type confusion, duplicate keys, or precedence differences
-- oversampling/reranking/hybrid-search stages that drop earlier authorization constraints
-- stale embeddings after source ACL changes, deletion, tenant moves, or index rebuilds
-- retrieval and answer caches keyed without user, tenant, role, corpus version, or filter state
-- cross-tenant existence inference through IDs, scores, timing, citations, or chunk metadata even when final text is refused
-- adversarial or duplicate content that dominates nearest-neighbor retrieval
-- embedding export, inversion, reconstruction, or linkage when vectors are returned or broadly readable
-
-Use at least two principals and distinct documents. Inspect raw candidate IDs, context-bound chunks, and the final answer. Post-search filtering may cause ranking interference or expose candidates to an intermediate service without proving that the model or user received another tenant's content; state the exact boundary crossed.
-
-Do not apply LLM09 merely because an application retrieves documents. Require an embedding or vector-similarity property; route authorization flaws in vectorless retrieval to the conventional access-control or information-disclosure skill.
-
-## LLM10:2026 Improper Output Handling
-
-Treat every model-generated string, object, URL, code block, tool argument, control sequence, and structured-output field as attacker-influenceable.
-
-Trace output into its actual consumer:
-
-- HTML, Markdown, email, office-document, terminal, IDE, log, and rich-text renderers
-- shell/process APIs, SQL/NoSQL queries, templates, expressions, interpreters, and generated code accepted into builds
-- URLs, webhooks, redirects, image fetches, browser navigation, and server-side requests
-- file paths, archive entries, object keys, configuration, logs, and serialized objects
-- authorization, moderation, routing, pricing, eligibility, or workflow decisions
-
-Validate with the sink-specific skill (`xss`, `sql_injection`, `nosql_injection`, `rce`, `ssrf`, `path_traversal_lfi_rfi`, `ssti`, or `insecure_deserialization`). JSON/schema conformance does not establish authorization or semantic safety; validate types, ranges, identities, destinations, and business rules after parsing.
-
-## Reproducibility and Reporting
-
-- Preserve application/model/prompt/tool/corpus versions and all generation parameters available to the application.
-- Compare baseline and adversarial trials, record attempt and success counts, and distinguish deterministic application behavior from stochastic model behavior.
-- Validate authorization, data origin, downstream effects, persistence, or measured consumption outside the model transcript.
-- Split reports when weaknesses have independent reproductions, trust boundaries, owners, or remediations. Otherwise report one technical root cause and mention additional OWASP mappings as chain context.
-- Use `create_dependency_report` only for verified advisory-matched dependency CVEs. Use `create_vulnerability_report` for dynamically verified application, model, RAG, agent, or supply-chain findings.
-
-## Summary
-
-Test the LLM application as a data-and-authority system, not as a chatbot prompt. Complete 2026 coverage requires model behavior, application code, retrieval, tools, supply chain, downstream sinks, and resource controls to be evaluated together while keeping their root causes distinct.

-description: Reproducible, reviewable HTTP request chains and response assertions with Hurl for authorized multi-step security validation, vulnerable-versus-fixed regression cases, captured values, and low-rate semantic oracles
----
-
-# Hurl Security Regression Playbook
-
-Use [Hurl](https://hurl.dev/) when a security proof requires an ordered HTTP session whose requests, captured values, and assertions should be code-reviewed and replayed. It is well suited to authentication flows, redirects, cookies, CSRF tokens, upload lifecycles, patch regression, and paired semantic-differential cases.
-
-Hurl sends exactly what the file describes. It does not make state-changing requests safe. Review scope, methods, targets, and captured secrets before every run.
-
-## Install
-
-Prefer an official release binary or package. On macOS:
-
-```bash
-brew install hurl
-hurl --version
-```
-
-Official alternatives include release packages and `cargo install --locked hurl`; see [installation](https://hurl.dev/docs/installation.html). Record the tool version with results.
-
-## Minimal Chain
-
-```hurl
-# lab-regression.hurl
-GET {{base_url}}/session
-HTTP 200
-[Captures]
-csrf: xpath "string(//input[@name='csrf']/@value)"
-[Asserts]
-header "Content-Type" startsWith "text/html"
-
-POST {{base_url}}/action
-Content-Type: application/x-www-form-urlencoded
-[FormParams]
-csrf: {{csrf}}
-operation: noop
-HTTP 204
-```
-
-Hurl keeps cookies across requests in the same file, so an explicit `Cookie` header is unnecessary here.
-
-Run one reviewed case against one authorized target first:
-
-```bash
-hurl --test --jobs 1 --connect-timeout 5s --max-time 15s \
-  --variable base_url=https://lab.example lab-regression.hurl
-```
-
-When credentials are required, pass them with `--secrets-file local-secrets.env`, keep that file outside version control, and avoid verbose/debug output that could expose headers or bodies. Use `--variables-file` only for non-secret environment values.
-
-## Designing a Security Regression
-
-- Assert the security invariant, not only a status code: denied identity, final normalized location, absence/presence of a structural field, unchanged object state, or exact benign result.
-- Capture only values needed by later requests. Do not write tokens, personal data, or response bodies into committed reports.
-- Encode a malformed but non-triggering control alongside the suspected case.
-- Run the same file against vulnerable and fixed builds through `base_url` or other explicit variables.
-- Keep state-changing methods in a clearly labeled lab/staging file; prefer no-op actions, inert markers, and cleanup requests.
-- Check every redirect step when the vulnerability crosses routing, origin, or authentication boundaries. Blindly following redirects can hide the relevant transition.
-- Use unique canaries so cached or pre-existing state cannot create a false positive.
-
-## Chain Structure
-
-Organize longer files around capability transitions:
-
-```text
-fingerprint -> establish session -> reach boundary -> prove primitive -> verify state -> cleanup
-```
-
-At each response, assert the condition required by the next request. A final success assertion cannot explain which earlier assumption failed.
-
-Useful Hurl features include:
-
-- captures from headers, cookies, JSONPath, XPath, and regex queries
-- assertions over status, headers, body, JSON/XML, redirects, and timing
-- request-local options and variables
-- `--test` plus JSON, JUnit, TAP, or HTML reports
-
-Consult the [Hurl manual](https://hurl.dev/docs/manual.html) for version-specific syntax instead of guessing an option.
-
-## Safety Rules
-
-- Use an explicit `base_url`; never derive the destination from untrusted response data without validating scheme, host, and port.
-- Review POST/PUT/PATCH/DELETE requests and server-side side effects before replay.
-- Set bounded timeouts and retries for the target; do not use polling as an unbounded brute-force loop.
-- Do not use Hurl for raw HTTP parser/smuggling cases when its HTTP stack normalizes the bytes being tested; use an appropriate raw harness in an isolated lab.
-- Use `--path-as-is` when literal `/../` or `/./` path segments are the behavior under test; otherwise Hurl's underlying URL handling can normalize them.
-- Redact reports. HTML/JSON/JUnit artifacts may contain request URLs, headers, captured variables, and response snippets.
-- Keep authentication material in local secret storage and use dedicated test accounts with minimum privilege.

----
-
-# Hypothesis Differential Testing
-
-Use [Hypothesis](https://hypothesis.readthedocs.io/) when a security property can be expressed over local code and failures are likely to hide in combinations of encoding, normalization, structure, or parser recovery. It is especially useful for comparing two implementations or checking that validation and consumption preserve the same meaning.
-
-Do not point unrestricted generators at a live service. Hypothesis is safest and most useful against pure local adapters with no network, subprocess, filesystem, or persistent-state side effects.
-
-## Install
-
-Use an isolated virtual environment and install a reviewed pinned version:
-
-```bash
-python -m pip install 'hypothesis==<reviewed-version>'
-```
-
-Official project: [Hypothesis](https://github.com/HypothesisWorks/hypothesis)
-
-## Start From an Invariant
-
-Write the security relationship before writing strategies. Examples:
-
-```text
-allowlist(raw) implies sink(canonicalize(raw)) remains inside the allowed origin/path
-validator(raw) accepts implies consumer(raw) assigns the same media type/structure
-parse_A(raw) and parse_B(raw) agree on message boundaries and authoritative fields
-serialize(parse(raw)) cannot introduce a delimiter, wildcard, traversal, or new field
-```
-
-A test that only checks “does not crash” can find robustness bugs but does not establish a security differential.
-
-## Minimal Differential Harness
-
-```python
-from hypothesis import given, settings, strategies as st
-
-
-def outcome(parser, raw):
-    try:
-        return ("accept", parser(raw))
-    except ExpectedParseError as exc:
-        return ("reject", type(exc).__name__)
-
-
-@settings(max_examples=250, deadline=500)
-@given(st.text(max_size=128))
-def test_security_boundary(raw: str) -> None:
-    checked = outcome(security_parser, raw)
-    consumed = outcome(sink_parser, raw)
-    assert equivalent_security_meaning(checked, consumed)
-```
-
-- Bound string/list/binary sizes, recursion, examples, and deadline.
-- Build structured inputs from relevant tokens rather than generating unrestricted noise.
-- Normalize expected accept/reject/error outcomes explicitly so ordinary parser rejection is not mistaken for a property-test failure.
-- Use `st.one_of`, `st.sampled_from`, `st.lists`, `st.binary`, `st.text`, and composite strategies to represent the actual grammar.
-- Add explicit edge seeds with `@example` for known delimiters and regressions.
-- Let Hypothesis shrink failures; the minimal counterexample is often the clearest explanation of the parser disagreement.
-
-## High-Value Strategy Axes
-
-- percent and double encoding, malformed escapes, mixed separators
-- Unicode normalization, replacement characters, surrogates, case folding, IDNA
-- dot segments, slash/backslash, absolute/relative paths, sibling-prefix collisions
-- duplicate, empty, first/last, comma-joined, or differently cased fields
-- declared length versus actual bytes, truncation, padding, and terminators
-- nested objects, parser depth, ordering, unknown keys, and error recovery
-- serialize/deserialize round trips and version-to-version behavior
-
-Generate only axes supported by the target's transformation graph. Cartesian payload spraying obscures causality.
-
-## Reproducibility
-
-- Keep the minimized failing example as a normal regression test.
-- Preserve code revision, dependency lock, locale, platform, and parser/library versions.
-- Keep Hypothesis's example database in a task-specific artifact directory when replay across runs matters.
-- For CI, rely on stored explicit regressions for critical cases; randomized discovery supplements them.
-- Classify nondeterminism before suppressing health checks. Timing, global state, environment, and shared caches can create flaky false differentials.
-
-## Safety and Resource Controls
-
-- Adapt target functions so tests cannot reach the network or execute commands.
-- Use temporary directories and non-secret corpora for parsers that require files.
-- Put native parsers in a disposable, networkless process/container with CPU, memory, file-size, and process ceilings.
-- Do not disable deadlines globally to hide hangs; isolate and bound intentionally slow examples.
-- A crash, timeout, or excessive allocation is a robustness result. Prove a security boundary or exploitability separately.
-- Never reuse captured credentials, customer content, or production requests as generative corpora without sanitization.

-description: Security testing for authorized AI agents and MCP-style tool ecosystems, covering effective authority, tool/resource/prompt inventory, confused-deputy behavior, side-effect authorization, cross-tenant isolation, executable component supply chain, shadow integrations, and repeatable safety regression
----
-
-# Agentic System Security
-
-Use this skill when an AI system can select tools, retrieve resources, invoke remote/local services, maintain memory, delegate to other agents, or install skills/plugins. Pair it with `llm_prompt_injection` for instruction attacks and classic vulnerability skills for the downstream HTTP, cloud, filesystem, identity, or code-execution sink.
-
-Prompt text is not an authorization boundary. Treat the agent runtime as a confused deputy whose effective authority is bounded by the union of its credentials, tools, resources, network reach, filesystem access, delegated agents, and approval policy, then reduce that upper bound to the actually reachable subset by tracing token audience, scopes, routing, target authorization, environment, and approval flow.
-
-## Effective-Authority Map
-
-Draw the complete path:
-
-```text
-user / external content
-  -> model context and memory
-  -> planner / router / policy
-  -> tool or delegated agent
-  -> credential and target system
-  -> side effect / returned data
-```
-
-Inventory, for each node:
-
-- trust source and tenant/user ownership
-- immutable component identity, package/server name, version, and transport
-- tools, resources, prompts, model endpoints, plugins, skills, and MCP servers
-- credential identity, issuer, audience/resource, subject, tenant, scopes/roles, expiry, downstream token exchange, environment, and where it is injected
-- readable data and write/execute capabilities
-- network/listener exposure and test-versus-production target
-- argument validation, authorization point, approval point, schema/argument digest, delegated principal propagation, and audit log
-- data returned to the model and whether it can contain new instructions
-
-Test from the lowest-privileged realistic user and device. The key comparison is the user's authority versus the agent/tool credential's authority.
-
-## Core Test Areas
-
-### Shadow Agent and AI Discovery
-
-Do not assume the approved application inventory contains every agent, model endpoint, browser extension, local MCP server, or AI API integration. Correlate multiple independent signals:
-
-- DNS/proxy/egress logs for first-seen model, agent, vector database, plugin, and AI SaaS domains
-- OAuth/SSO grants, enterprise-app consent, service principals, API tokens, and unusual delegated scopes
-- endpoint processes, browser extensions/native messaging, listening loopback ports, and MCP client/server configuration
-- repository, CI/CD, secrets-manager, and container/image references to model providers, tool servers, and AI credentials
-- cloud-hosted model endpoints, notebooks, functions, gateways, and procurement/expense/SaaS inventory
-
-Baseline local discovery from the host before interpreting network or SSO signals:
-
-```bash
-# macOS
-lsof -nP -iTCP -sTCP:LISTEN
-ps -axo pid,ppid,user,command
-
-# Linux
-ss -lntp
-ps -eo pid,ppid,user,args
-
-# Windows PowerShell
-Get-NetTCPConnection -State Listen | Select-Object LocalAddress,LocalPort,OwningProcess
-Get-Process | Select-Object Id,ProcessName,Path
-
-# Cross-platform config and credential leads
-rg -l 'mcpServers|modelContextProtocol|OPENAI_API_KEY|ANTHROPIC_API_KEY|AZURE_OPENAI_ENDPOINT' <reviewed-roots>
-```
-
-Correlate each listener or config hit to PID/container, parent process, binary hash/version, launch command, config file, destination, and credential reference before calling it an active agent component. A loopback listener is a lead, not proof of reachable authority.
-
-Classify each discovered integration by data read, data write, external communication, execution, identity/admin, and production reach. Human-validate attribution before treating a domain or key name as active AI use. Inspect unauthenticated local MCP/agent listeners separately; network inventory tools often miss loopback-only services.
-
-### Tool Discovery and Argument Boundaries
-
-- Enumerate advertised and conditionally available tools, resources, prompts, schemas, annotations, and delegated agents.
-- Compare what the UI exposes with what the protocol/runtime accepts directly.
-- Test missing, extra, duplicate, nested, oversized, alternate-type, and cross-tenant identifiers in tool arguments.
-- Validate scheme/host/path, filesystem paths, cloud resource IDs, recipient identities, SQL/query fields, and command arguments at the tool boundary.
-- Treat tool descriptions, names, examples, resource metadata, and returned content as attacker-influenceable unless provenance is enforced.
-- Canonicalize tool identity as `server identity/version + endpoint/transport + tool name + schema digest`; do not collapse two identically named tools from different servers into one trust decision.
-- Treat protocol hints such as `readOnlyHint`, `destructiveHint`, `idempotentHint`, and `openWorldHint` as untrusted metadata, not authorization.
-- Verify that unknown tools or schema-invalid calls fail closed without falling back to a broader handler.
-
-### Confused Deputy and Consequential Actions
-
-- Ask whether untrusted user/document/tool text can choose the tool, target, identity, or action.
-- Test read-to-write escalation: a summarizer should not send, publish, delete, purchase, deploy, or modify because retrieved text requests it.
-- Test whether approval binds the exact server identity/version, tool name, schema digest, normalized arguments, credential, target, side effect, and expiry. Revalidate those fields immediately before execution; a generic “continue?” is weak if arguments can change after approval.
-- Exercise replay, retry, parallel calls, partial failure, cancellation, and delegated execution for duplicate or bypassed actions.
-- Prove impact at the actual target and audit log. Model narration or a fabricated tool result is not evidence.
-- Use dry-run/no-op/read-only operations first; require explicit human approval for consequential operations.
-
-### Identity, Tenant, and Environment Isolation
-
-- Vary user, workspace, tenant, session, conversation, and delegated-agent identity independently.
-- Test whether one tenant can reference another tenant's resources, tool sessions, caches, vector entries, files, or credentials.
-- Check whether development/test tools or credentials can reach production, and whether local tools inherit broad workstation authority.
-- Verify credential scoping at the target service, not only in the agent's application logic.
-- Confirm memory and cached tool results are partitioned and revoked when identity or role changes.
-
-### MCP and Local Tool Servers
-
-- Inventory stdio, streamable HTTP, SSE/legacy, and custom transports; record bind address, origin/auth controls, process command, environment, and lifecycle.
-- Look for unauthenticated loopback services reachable from browsers, containers, local users, SSRF, port forwarding, or shared hosts.
-- Compare `tools/list`, `resources/list`, and `prompts/list` results across identities, but do not assume listing means calling is authorized.
-- For each tool, validate the same authorization and argument checks through every supported transport.
-- Treat server-launched subprocess configuration, environment variables, and working directories as sensitive executable configuration.
-- For HTTP/SSE transports, validate OAuth issuer, signature, expiry, audience/resource, tenant, and scope claims at the server boundary. Reject tokens minted for the wrong audience, and do not treat a session ID as identity.
-- For downstream APIs, do not pass through the same bearer token unless the target explicitly authorizes that audience and principal. Separate upstream MCP authentication from downstream target authorization.
-- For browser or loopback OAuth, review redirect URI, state/PKCE handling, localhost binding, and consent proxying. Treat metadata fetches and tool discovery on remote servers as SSRF-relevant surfaces.
-- For stdio servers, the launch command and environment are already code execution. Discovery must not execute an unreviewed server binary or mutable package tag.
-
-### Executable Component Supply Chain
-
-Every skill, plugin, MCP server, model adapter, package, and update channel is an executable or behavior-shaping dependency. Record:
-
-- canonical source, publisher, package namespace, pinned version and integrity/provenance
-- install/update mechanism, manifest/lockfile/config source, mutable tags, automatic updates, and rollback path
-- declared and effective permissions, credentials, filesystem/network access
-- transitive dependencies and lifecycle scripts
-- review/approval ownership and last verification date
-
-In agent and MCP configs, inspect `command: npx` with `-y` and a bare package or
-binary name. The process can fetch code without an interactive prompt and then
-run it with the agent's authority. Load `npx_confusion` to determine whether the
-name resolves locally, becomes a public package spec, and belongs to the
-intended publisher.
-
-Test missing/private-name fallback, typosquatting exposure, mutable remote instructions, compromised-update blast radius, and whether an “instruction-only” component can invoke tools or modify executable files. Resolve `latest`, floating git refs, and mutable image tags to immutable versions or digests before launch. Do not claim or publish contestable package names as proof, and do not execute unknown packages just to discover what they are.
-
-Load `infrastructure_lifecycle` when a skill, plugin, MCP server, model adapter, tool-schema origin, package namespace, or update endpoint is retired, mutable, or externally reassignable. Passive receipt of an agent heartbeat or catalog request does not authorize returning tool definitions, prompts, commands, or executable content.
-
-### Output, Telemetry, and Failure Modes
-
-- Validate model/tool output before it reaches HTML, shell, SQL, URLs, file paths, templates, or a second agent.
-- Ensure logs record initiating user, tool/server identity, sanitized arguments, approval, target, result, and correlation ID without storing secrets.
-- Test timeout, tool error, truncated output, malformed result, model retry, and policy-service failure. Failures should not silently switch to a more privileged tool or credential.
-- Verify kill switches, credential revocation, and disabling a component actually terminate active sessions and queued work.
-
-## Safe Testing Workflow
-
-1. **Map** every capability and trust boundary before injecting prompts.
-2. **Classify** tools as read, write, execute, communicate, identity/admin, or external-cost.
-3. **Establish controls** with dedicated test tenants, synthetic data, read-only credentials, budgets, and target allowlists.
-4. **Probe one boundary** at a time: selection, arguments, authorization, approval, execution, result handling.
-5. **Validate the side effect** in the target system and audit trail; compare denied and allowed identities.
-6. **Chain confirmed primitives** using the effective-authority and capability map from this skill.
-7. **Clean up and revoke** created data, sessions, tokens, and local servers.
-8. **Turn each confirmed case into a regression** across relevant models, prompts, tools, roles, and environments.
-
-## MCP Inspector (Conditional)
-
-Use the official [MCP Inspector](https://github.com/modelcontextprotocol/inspector) only against a reviewed local/test server:
-
-```bash
-npx @modelcontextprotocol/inspector@<reviewed-version> --cli \
-  --config reviewed-mcp.json --server test-server \
-  --method tools/list --format json
-```
-
-- Current upstream requirements should be checked before pinning; as of August 12, 2026, MCP Inspector 2.1.0 requires Node.js `>=22.19.0`.
-- Prefer CLI/TUI and loopback binding over exposing the web UI.
-- Preserve the generated API token; never disable authentication or bind the process-spawning backend to an external interface.
-- Do not publish ports 6274/6277 or pass through the Docker socket/host devices.
-- `tools/list` is protocol-read-only, but launching/initializing an arbitrary stdio server executes it and list handlers can still have process-side effects. Review the server command/config first. Calling a tool can perform real external actions.
-- Treat the inspected server command/config as executable; `npx` also downloads code, so pin a reviewed package version for repeatable or sensitive work.
-
-## Regression With Promptfoo (Conditional)
-
-[Promptfoo](https://github.com/promptfoo/promptfoo) can encode a bounded model/tool safety matrix after manual validation:
-
-```bash
-npx promptfoo@<reviewed-version> eval
-```
-
-- Current upstream engine constraints should be checked before pinning; as of August 12, 2026, Promptfoo documents Node.js `^20.20.0` or `>=22.22.0`.
-- Use synthetic prompts/data and a dedicated test provider/project.
-- Provider calls transmit data externally and can incur cost even when evaluation orchestration is local. Set request/concurrency and spending ceilings.
-- Pin model, provider, prompt, tool schema, retrieval corpus revision, and evaluator versions.
-- Include allowed and denied controls across roles/tenants; use multiple runs for nondeterministic outcomes.
-- Automated red-team labels are leads, not findings. Confirm the real tool call, data access, or side effect manually.
-- Store redacted results; evaluation logs can contain system prompts, secrets, retrieved data, and tool arguments.
-
-## Validation
-
-A report must include:
-
-1. initiating identity, tenant, model/runtime, and exact component versions
-2. effective-authority map and relevant tool/resource schema
-3. untrusted input source and decision boundary crossed
-4. exact target-side operation or data access, with redacted audit evidence
-5. denied identity/input and allowed control results across repeat runs
-6. credential, feature, approval, environment, and user-interaction prerequisites
-7. cleanup/revocation and a bounded regression case
-
-## False Positives
-
-- The model claims a tool ran but the target and audit log show no action.
-- A listed tool cannot be invoked by the tested identity or validates arguments safely.
-- A safety refusal changes wording but effective capability remains denied.
-- Cross-session output is synthetic, cached public data, or hallucinated rather than another user's data.
-- A scanner flags an instruction string without showing that it reaches a privileged decision or sink.
-- A component has broad declared permissions but the runtime credential/network policy prevents the claimed access.
-
-## Summary
-
-Agent security is capability security. Map the real authority carried through models, tools, credentials, plugins, and delegated agents; validate authorization and approval at the target-side effect; treat every installed component as executable supply chain; and preserve each confirmed boundary failure as a bounded regression.

-name: argument-injection
-description: Test shell-free command argument injection across argv builders and CLI parsers, including option smuggling, response/config-file parsing, argument-boundary reparsing, and Windows Unicode-to-ANSI Best-Fit transformations
----
-
-# Argument Injection
-
-Use this skill when attacker-influenced data reaches a trusted command-line program, even when no shell is involved. The security question is whether the input changes the program's **option set, operands, configuration, subcommand, or downstream parser state**.
-
-Load `rce` when a shell parses the command string. Load `semantic_confusion` when validation and the final CLI/filesystem/configuration consumer see different representations.
-
-## Model Every Parser Boundary
-
-Build the actual transformation chain:
-
-```text
-request value
-  -> application validation
-  -> argv builder or command-line string serializer
-  -> OS/process creation API
-  -> runtime argv construction
-  -> target option parser
-  -> response/config/auth file parser, URL parser, or subcommand
-```
-
-Do not treat all process APIs alike:
-
-- POSIX `execve(path, argv, envp)` and list-form subprocess APIs preserve array-element boundaries. Whitespace inside one element does not create another argument.
-- Shell/string forms introduce shell tokenization before the target program sees `argv`.
-- Windows process creation commonly serializes an argument array into one command-line string and lets the child runtime parse it back. Quoting rules differ across CRTs and applications.
-- Some programs deliberately reparse an argument as a response file, configuration file, URL, expression, template, or nested command language.
-
-Record the exact API, platform, runtime, target binary/version, option parser, and final `argv` observed by the child.
-
-## Primitive 1: Option and Subcommand Injection
-
-An attacker-controlled value placed where an operand is expected can be interpreted as an option when it begins with an option prefix:
-
-```text
-intended: ["tool", USER_VALUE]
-supplied: USER_VALUE = "--output=/controlled/path"
-actual:   tool parses an output option instead of an operand
-```
-
-Inventory security-relevant option classes rather than memorizing one payload:
-
-- output, upload, extraction, log, cache, plugin, template, or configuration paths
-- alternate URL schemes, proxies, certificates, credentials, and authentication files
-- hooks, helpers, filters, interpreters, external programs, or dynamic libraries
-- config overrides, environment definitions, working directories, and search paths
-- subcommands that expose administrative, import/export, restore, diagnostic, or execution features
-
-Check whether the target supports `--` as an end-of-options marker and whether the application places it before the untrusted operand. Do not assume every CLI honors `--`, or that it applies after a subcommand switches to a second parser.
-
-## Primitive 2: Argument-Boundary Breakout
-
-Require a component that reparses or reconstructs arguments. Candidate boundaries include:
-
-- shell or command-string construction
-- Windows quoting/escaping mismatches between parent and child runtimes
-- newline-, NUL-, delimiter-, or quote-sensitive custom launchers
-- wrappers that join an array and later split it
-- CGI/interpreter mappings that turn request data into command-line options
-
-Distinguish these outcomes:
-
-```text
-["tool", "user --flag"]       # one argv element; no split by execve
-["tool", "user", "--flag"]  # extra argv element reached the target
-["tool", "@args.txt"]        # one element, then reparsed by the target
-```
-
-Logs often render arrays as strings and can falsely suggest splitting. Capture the child's real arguments through source instrumentation, a wrapper process, debugger, audit trace, `/proc/<pid>/cmdline`, or the platform equivalent.
-
-## Primitive 3: Response, Config, and Authentication Files
-
-Many trusted programs consume a second language after argv parsing:
-
-- `@response-file` syntax used by compilers, linkers, JVM tooling, and custom launchers
-- `--config`, `-K`, credentials/auth files, include files, and rc/profile paths
-- newline-delimited key/value files generated from attacker-controlled fields
-- file contents where control characters create a new directive, identity, host, or option
-
-Trace both attacker influence over the **file path** and influence over the **file content**. Correct shell quoting does not protect a file that is later tokenized by a different grammar. Record duplicate-key behavior, newline rules, comments, escaping, include directives, and first/last-value precedence.
-
-## Windows Unicode-to-ANSI Best-Fit
-
-On Windows, narrow-character APIs and CRT startup paths can convert Unicode command-line, environment, or filesystem data into an ANSI code page. Best-Fit mappings may introduce ASCII characters after earlier validation.
-
-Relevant boundaries include:
-
-- `GetCommandLineA` or a narrow `main(int, char **)` startup path
-- `GetEnvironmentVariableA`, `GetCurrentDirectoryA`, and narrow filesystem APIs
-- framework or native-extension transitions from UTF-16 strings to an ANSI code page
-
-`CommandLineToArgvW` is the documented Windows command-line parser; there is no documented `CommandLineToArgvA`. Determine which CRT or application-specific parser constructs narrow `argv`.
-
-Treat mappings as code-page-specific hypotheses, not universal payloads. Candidate transformations include soft hyphen to `-`, fullwidth/compatibility slash characters to `/` or `\`, and compatibility quotes or letters to ASCII equivalents. Capture:
-
-- submitted Unicode code points and encoded bytes
-- active system/process code page
-- wide string before conversion
-- narrow bytes and final `argv` or filesystem path after conversion
-
-Using wide-character APIs removes this particular conversion boundary but does not fix ordinary option injection.
-
-## Reconnaissance
-
-In source, locate process creation and work forward into the consumer:
-
-```text
-exec*  posix_spawn  subprocess  ProcessBuilder  Runtime.exec
-CreateProcess  ShellExecute  child_process  os/exec  Command
-```
-
-For each attacker-controlled argument, answer:
-
-1. Is it a distinct argv element or part of a command string?
-2. Can it begin with the target's option prefix?
-3. Is an end-of-options marker supported and correctly positioned?
-4. Does a wrapper, CRT, shell, or target reparse it?
-5. Can it select a response/config/auth file or inject directives into one?
-6. Which target option or subcommand turns that control into read, write, request, identity, or execution capability?
-
-For black-box testing, compare an ordinary operand with option-prefixed, delimiter-bearing, control-character, and platform-specific Unicode variants. Match tests to options that actually exist in the deployed binary/version.
-
-## Validation
-
-- Show the final `argv` or secondary parser input, not only the application log line.
-- Pair the candidate with a control where the same bytes remain a literal operand.
-- Demonstrate the exact option, directive, subcommand, path, or handler selected.
-- Reproduce against the deployed binary, runtime, code page, and configuration.
-- Separate option control, additional-argument control, arbitrary directive control, and command execution; they are different primitives.
-
-## False Positives
-
-- The input is one argv element and the target treats it only as a positional operand.
-- `--` is supported, placed before the value, and not bypassed by a subparser.
-- A strict allowlist prevents option prefixes and all later transformations preserve it.
-- A delimiter appears only in logging or display formatting.
-- A response/config path is controllable but its contents or directives are not.
-- A Unicode character is accepted but no narrow/Best-Fit conversion occurs.
-- The injected option exists on another release or platform but not the deployed target.
-
-## Remediation
-
-- Use argument-array process APIs and avoid shell/string construction.
-- Insert `--` before untrusted operands where every relevant parser supports it.
-- Validate operands against the target CLI's grammar, not a generic shell blacklist.
-- Fix security-sensitive option names and configuration paths in trusted code.
-- Generate configuration/auth files with a format-aware serializer that rejects control characters and ambiguous duplicates.
-- On Windows, keep data in wide-character APIs and verify child-runtime parsing rules.
-- Enforce authorization again at the privileged operation selected by the CLI.
-
-## Summary
-
-Argument injection is control of a trusted program's behavior through its argv or a parser reached from argv. Preserve parser boundaries in the model: list-form execution, command-string tokenization, Windows runtime conversion, option parsing, and response/config-file parsing are distinct stages with distinct exploit conditions.

 ## Validation
 
-1. State the protected data, action, output, or decision invariant that the payload violates
+1. Show a concrete, repeatable payload that changes model behavior against the developer's intent

 ## Pro Tips
 
-1. Prompt instructions and in-band guardrails are not authorization boundaries; focus on deterministic controls and capability/sink impact
+1. Prompt injection is not "solved" by asking the model nicely — assume in-band guardrails are bypassable and focus on capability/sink impact
 2. Indirect injection is the higher-severity, under-tested vector — always test content the model *ingests*, not just the chat box
 3. Chase the sink: an injection is only critical if it reaches a tool, another system, or an unescaped renderer
-4. Test whether the deployed renderer fetches model-generated external resources and what data it includes; Markdown syntax alone proves nothing
-5. Map exactly who can write RAG corpora and memory, who can retrieve them, and whether content crosses principals
+4. Markdown/HTML image rendering is a classic zero-click exfil channel — test it explicitly
+5. Treat RAG corpora and multi-tenant memory as attacker-writable until proven otherwise
 6. Encode/obfuscate to probe filter strength; combine with delimiter breakout
 7. Always confirm real, reproducible impact — model chatter is not a finding
 
 ## Summary
 
-LLM prompt injection is a trust-boundary failure, not a contest for clever wording. Test every direct, indirect, stored, multimodal, memory, and tool-result instruction path, then prove the violated application invariant at the real data, action, decision, or output boundary.
+LLM features are confused deputies wielding the application's privileges over untrusted text. The severity of prompt injection is determined by the model's connected tools, data, and output sinks — not by clever wording alone. Test direct and indirect vectors, prove impact at a real sink, and never trust in-band guardrails as a control.

 Subdomain takeover lets an attacker serve content from a trusted subdomain by claiming resources referenced by dangling DNS (CNAME/A/ALIAS/NS) or mis-bound provider configurations. Consequences include phishing on a trusted origin, cookie and CORS pivot, OAuth redirect abuse, and CDN cache poisoning.

-            ``scope`` (U/C), ``confidentiality`` / ``integrity`` /
-            ``availability`` (N/L/H). All 8 metrics are required when the
-            field is set, and the contextual score/vector are computed
-            from them — you never supply a score. Start from the
-            advisory's published metrics and change only what the
-            **source-to-sink trace** you recorded in
-            ``reachability_evidence`` proves is different here: derive
-            ``attack_vector`` / ``privileges_required`` /
-            ``user_interaction`` from what the entry point actually
-            requires, ``attack_complexity`` from the preconditions the
-            hops enforce, and the impact metrics from the data and
-            privileges reachable at the sink. When provided, this rating
-            determines the finding's severity; ``advisory_cvss`` stays as
-            the published reference. Send it on every report: when the
-            trace does not change the published rating, or when you could
-            not complete the trace, repeat the advisory's own metrics and
-            adjust only what the usage level itself proves (a package the
-            code never imports is normally ``N`` on all three impact
-            metrics), then say so in the reasoning.
-        contextual_cvss_reasoning: **Required.** Two to four detailed
-            sentences that a reviewer can verify without opening the repo:
-            how the application uses the package, which call sites or
-            configuration you inspected (repo-relative ``file:line``),
-            which input reaches the vulnerable code and whether an
-            attacker controls it, and what the adjustment therefore
-            changes. State the source-to-sink chain explicitly, hop by
-            hop, as ``entry point -> intermediate call -> package call``
-            with a ``file:line`` for each hop. Cite concrete evidence,
-            never a generic statement such as "low risk". The user reads
-            this text next to the adjusted score, so an adjustment
-            without it is discarded.
