feat(examples): scenario-based red-team suites for coding and customer-facing agent archetypes

## Objective

Build on #1162's general taxonomic red-team pack with **realistic, scenario-driven suites for the two agent archetypes agentv users actually build**: coding agents and customer-facing agents. Each suite tests a concrete attack scenario end-to-end with archetype-appropriate tool-trajectory assertions, fixtures, and rubrics — not just an OWASP-tagged prompt.

## Motivation

#1162 ships *taxonomic* suites (one file per OWASP LLM ID, structured by attack category). Necessary but not sufficient. A team adopting agentv to evaluate a customer-support agent or a coding agent needs to know "*does my agent leak another customer's invoice?*" or "*does it run `git push --force` to main when an issue body asks?*" — not just "does it pass LLM01."

Both kinds of pack should ship together: taxonomic gives auditors coverage breadth, scenarios give engineers something they can map to their real product.

This complements #1162 — it does not replace or block it.

This is content + fixtures, not core. Fits design principles:
- Lightweight core (#1) — zero changes to `packages/core` or `apps/cli`. Uses existing primitives (`tool-trajectory`, `llm-grader`, `code-grader`, `composite`, `not-matches-regex`).
- YAGNI (#5) — no new mechanisms. Fixtures are scripts in the existing `cli` provider style.
- Industry standards (#4) — scenarios drawn from documented public threat research (PromptArmor, Lasso Security on slopsquatting, [InjecAgent](https://arxiv.org/abs/2403.02691), [AgentDojo](https://arxiv.org/abs/2406.13352), [AgentHarm](https://arxiv.org/abs/2410.09024), [promptfoo agentic plugins](https://www.promptfoo.dev/docs/red-team/), MITRE ATLAS v5.4 agentic techniques).

Full PR adds **5–10 cases per suite** (not just one), each with realistic prompts and concrete assertion shapes.

## Seed sources (public, permissively licensed)

- **Coding agent**: PromptArmor research blog posts, Lasso Security slopsquatting research, public Anthropic Claude Code threat-model writeups, [Schuster et al. on backdoor code-gen](https://arxiv.org/abs/2007.02220), MITRE ATLAS v5.4 agentic technique pages.
- **Customer-facing**: [AgentDojo](https://github.com/ethz-spylab/agentdojo) (banking / Slack / travel / workspace cases — directly applicable), [InjecAgent](https://github.com/uiuc-kang-lab/InjecAgent), [promptfoo agentic plugins](https://github.com/promptfoo/promptfoo) (RBAC, BOLA, BFLA, hijacking, cross-session-leak; MIT — fork individual cases with attribution).

Each suite's README documents which seeds informed it.

## Design latitude

1. **Number of cases per suite**. Aim for 5–10 each — enough to differentiate vulnerable vs aligned targets, not so many that review drags. ~50–80 cases total across both archetypes.
2. **Fixture format**. MCP server fixtures should be a single JS file (no package install). DB mocks should be JSON. Avoid Docker / multi-service setups.
3. **Tool naming**. Use plausible tool names (`bash`, `read_file`, `db_query`, `send_email`, `issue_refund`) — don't invent ones. Match the names in `examples/features/` where applicable.
4. **Whether to include benign control cases**. Recommend yes — for each archetype, include 2–3 *benign* requests that look superficially similar to the attack but should succeed. Tests that the agent doesn't over-refuse (a real failure mode in production support agents).

## Acceptance signals

- `examples/red-team/archetypes/coding-agent/` and `examples/red-team/archetypes/customer-facing-agent/` exist with the suite files listed above.
- Each archetype has a `README.md` describing the threat model, the tools the suite assumes, and which fixtures it depends on.
- 5–10 cases per suite; 50–80 cases total across both archetypes.
- Every case is tagged per #1161's `governance` schema, including `owasp_agentic_top_10_2025` where the case is agent-specific.
- Each archetype includes 2–3 benign control cases (over-refusal guard).
- `agentv eval examples/red-team/archetypes/coding-agent/suites/destructive-git.yaml --target vulnerable-baseline` produces failures; against an aligned model produces near-100% pass.
- Same shape works for customer-facing-agent suites.
- README per archetype documents seed corpus + license per case family.

## Non-goals

- Changes to `packages/core` or `apps/cli`. This is examples + fixtures only.
- New grader types. Reuse `tool-trajectory`, `llm-grader`, `code-grader`, `composite`, `not-matches-regex`, `not-contains` from existing primitives.
- A live MCP server, a real database, or any service that needs to be running for tests. Fixtures are static or trivially scripted.
- Bundled attacker LLM. Strategy plugins (Crescendo, GOAT, tree-of-attacks) remain a separate issue.
- A web UI showcasing results. Reports come from existing agentv output.
- Claims about specific commercial agents' vulnerabilities. Cases test patterns; targets are the user's choice.
- Coverage of every conceivable scenario. Pick the highest-signal handful per archetype.

## Dependencies

- Blocked by #1161 (`governance` metadata schema) — every case relies on it.
- Soft-blocked by #1162 (general red-team pack) — graders (`refusal.md`, `pii-leak.md`, `tool-abuse.md`) live there. Can land in either order; if this PR lands first, it ships its own minimal graders that #1162 then deduplicates.

## Manual test plan (green-path e2e)

Assumes #1161 and #1162 merged.

1. **Inventory.**
   ```bash
   ls examples/red-team/archetypes/coding-agent/suites/
   ls examples/red-team/archetypes/customer-facing-agent/suites/
   ls examples/red-team/archetypes/coding-agent/fixtures/
   ```
   **Green:** at least 7 suites under coding-agent, 7 under customer-facing-agent; fixtures present.

2. **Threat-model docs render.**
   ```bash
   cat examples/red-team/archetypes/coding-agent/README.md
   cat examples/red-team/archetypes/customer-facing-agent/README.md
   ```
   **Green:** each names assumed tools, expected fixtures, threat scope, seed corpus + license.

3. **Every case is tagged per #1161.**
   ```bash
   for f in examples/red-team/archetypes/*/suites/*.yaml; do
     yq '.tests[] | select(
       (.metadata.governance.owasp_llm_top_10_2025 // []) +
       (.metadata.governance.owasp_agentic_top_10_2025 // []) | length == 0)' "$f"
   done
   ```
   **Green:** prints nothing.

4. **Vulnerable-target differential — coding agent.** Configure a target that simulates a permissive code agent (in `.agentv/targets.yaml`):
   ```yaml
   - name: vulnerable-coder
     provider: cli
     command: ./examples/red-team/archetypes/coding-agent/fixtures/echo-coder.sh
   ```
   ```bash
   agentv eval examples/red-team/archetypes/coding-agent/suites/destructive-git.yaml --target vulnerable-coder
   ```
   **Green:** at least one case fails on the tool-trajectory assertion (`git push --force` was called).

5. **Aligned-target differential — coding agent.**
   ```bash
   agentv eval examples/red-team/archetypes/coding-agent/suites/destructive-git.yaml --target claude-opus-4-7
   ```
   **Green:** materially higher pass rate; refusal rubric reasoning explains each verdict.

6. **Vulnerable-target differential — customer-facing.** Same shape against `pii-cross-customer-disclosure.yaml` with a permissive support-agent fixture.
   **Green:** at least one case fails on the not-matches-regex or tool-trajectory assertion.

7. **Over-refusal control.** Run the *benign* cases tagged `benign: true` (or under a `benign/` subdir) against the aligned target.
   **Green:** all benign cases pass — agent isn't refusing legitimate requests.

8. **MCP fixture works without external deps.**
   ```bash
   node examples/red-team/archetypes/coding-agent/fixtures/poisoned-mcp-server.js --self-test
   ```
   **Green:** prints a smoke-test result; no `npm install` required.

9. **Coverage across taxonomies.**
   ```bash
   for f in examples/red-team/archetypes/*/suites/*.yaml; do
     yq -r '.metadata.governance.owasp_llm_top_10_2025[]?' "$f"
     yq -r '.metadata.governance.owasp_agentic_top_10_2025[]?' "$f"
   done | sort -u
   ```
   **Green:** OWASP LLM set covers at least LLM01, LLM06, LLM07; agentic set covers at least T1, T7.

10. **License / provenance is auditable.**
    ```bash
    grep -iE 'license|source|origin' examples/red-team/archetypes/*/README.md
    ```
    **Green:** every seed corpus named with its license under each archetype.

Fail conditions:
- Any change to `packages/core/` or `apps/cli/`.
- Any case missing a governance tag.
- Fixtures requiring `npm install` / external services / Docker / a live database.
- Cases with explicit harmful payloads (CSAM, weapon synthesis, self-harm).
- Customer names, account numbers, or addresses that look like real WiseTech / partner data — all fixtures must be synthetic.

## Code review quality gate

Reviewers should treat this as a **content + fixtures PR**. agentv core is off-limits.

**Request changes if the PR includes any of**:
- Any change to `packages/core/` or `apps/cli/`. The diff there must be empty.
- A new grader type. Compose existing primitives only.
- Any new dependency (`package.json`, `requirements.txt`, etc.) — fixtures stand alone.
- Fixtures requiring a network call, a Docker container, a database, or `npm install`.
- A live or scriptable attacker LLM. Strategy generation is a separate issue.
- Cases without a governance tag (test step 3 fails the build automatically).
- Any case naming a real company, real customer, or real product as the *target* of a successful attack. Cases test patterns; the user supplies their own target.
- Personally-identifying data in fixtures (real names / emails / addresses / IDs). All fixtures synthetic.
- Explicit harmful payloads (CSAM, weapon synthesis, self-harm). Seeds must come from corpora that have already curated these out.
- Suites with > 15 cases each (hint that the implementer is padding rather than picking high-signal). Ask: "what does each new case test that an existing one doesn't?"
- Missing benign control cases per archetype.
- README that recommends a commercial governance / red-team product as the answer (mention as ecosystem context only, not as a steer).

**The bias on review**: ask the author to demonstrate the *differential* — one suite, one vulnerable target, one aligned target, side-by-side reports. If the differential isn't dramatic, the cases aren't sharp enough yet.
