Adversarial Review

/adrev - run a single hostile lens against a plan or any entity: a file, doc, PR, issue, directory, or an idea stated inline. The lead personally applies the adrev-reviewer attack criteria by default: it attacks premises, hunts failure modes, steelmans the strongest case against, and checks falsifiability and reversal costs.

For plans, a designated writer applies supported findings after evidence-backed lead review. Explicit cross-provider mode adds a restricted reviewer and bounded critic exchange; preserve its report and evidence ledger. --no-apply or a natural-language opt-out returns findings without target changes. Headless mode applies only with explicit --apply; writable markdown documents can also opt in explicitly.

How It Relates to Other Review Modules

Surface Scope Modifies the target?
/adrev One adversarial lens, any entity Plans: designated writer by default; other markdown only with explicit --apply
/document-review 7 lenses, docs headed to execution Never - findings are presented
/ce-review, pr-review-toolkit, /code-review Code diffs and PRs Via review comments / fixes
/editorial-critique Prose style Optional --fix

Use /document-review for the full pre-execution gate on a plan; use /adrev when you want the premise-challenge lens alone, on anything, with the plan updated when it is a plan.

Pre-commitment, Assumptions and Rollback

Three steps shape the battery:

  • Pre-commitment. Before the full read, the reviewer writes down 3-5 predicted problem areas from the title, headings and goal alone, then checks each one against the full text. Each prediction ends confirmed, refuted or unchecked.
  • Assumption table. The premise attack rates each key assumption VERIFIED, REASONABLE or FRAGILE. Fragile assumptions are attacked first.
  • Rollback analysis (plan targets). For each state-changing step, what is the recovery path if it fails partway, and is it documented or assumed?

Standalone output adds two arrays beside findings and survived: predictions[] (id, area, reason, outcome, optional finding) and assumptions[] (id, assumption, rating, evidence, optional finding). Nothing in CCGM parses these fields by name: /adrev, /xplan Phase 5.7 and /etp apply the battery from the agent file, and the cross-agent-review native schema supplies its own findings format. Consumers that read the standalone JSON should ignore unknown keys.

The Attack Battery

  1. Premise attack - load-bearing assumptions the author has not realized they are making
  2. Falsification test - claims with no articulated way to know if they are wrong
  3. Failure-mode hunt - empty input, partial failure, concurrency, scale, clock edges, careless and malicious users
  4. Strongest opposing case - steelman the alternative, including do-nothing
  5. Reversal-cost check - expensive-to-undo decisions with thin justification
  6. Second-order effects - assume it ships and works; who adapts to it, games it, or becomes load-bearing on it

Native pilot findings use critical/high/medium/low severity and include stable IDs, requirement references, exact evidence and remedies. The report also lists what the target survived - a clean verdict is only credible when the attacks are shown.

Plan Execution Tenets (plan targets)

Beyond the battery, a plan is a contract for autonomous execution, so plan targets get four additional checks that are requirements, not judgment calls - if the plan fails one, apply mode fixes it (adds/expands the section), it is not merely noted:

  1. Human interaction is minimized and bucketed to the edges - no human step an agent could do via CLI/API; unavoidable human work is front-loaded before execution or deferred to the end, never wedged mid-run where it stalls the whole run.
  2. A follow-up-completion contract is present - the plan requires that any follow-on work discovered during execution is completed before execution is reported complete; the completion checklist includes "no open in-scope follow-up work"; only genuinely human-blocked items may remain open.
  3. Enough decision context to direct unplanned work without a human - the plan carries the software's mission, the codebase's governing conventions, and its own decision principles, so an agent can deduce how to handle an unplanned follow-on item. Missing context is expanded into the plan on apply.
  4. A comprehensive autonomous E2E test suite - every testable surface maps to a real end-to-end test (not mocks), wired into CI as a blocking merge gate, so the suite (not the user) is the ready-to-merge oracle. For existing repos, coverage gaps in touched areas are filled optimistically. Thin coverage is expanded into Section 8 on apply.

The four reinforce each other: decision context (3) lets an agent finish follow-on work (2) without a human, which keeps execution human-free mid-run (1); the E2E suite (4) makes "done" verifiable without the user, so the whole run can certify itself green.

The Apply Protocol (plans)

The lead judges findings against the actual artifact, goal and evidence; one designated writer applies supported authorized changes, followed by affected checks and personal review. --cross-provider or explicit natural-language opt-in enables an optional restricted opposite-provider run. Its early preflight checks both native binaries/login status; default lead review needs no provider authentication. The optional policy validates frozen evidence, dispositions, native acknowledgments and a caller-attested host receipt. record-check records supplied output; it does not execute checks or prove they ran.

Provider errors stop that optional run and preserve reports/findings. The lead may separately evaluate delivery with normal checks without claiming the stopped run approved; coordinator repairs need no recursive consensus. Use the common private directory ~/.claude/cross-agent-review/<run-id>/ and, under advisor mode, only the installed policy shim. Marketplace-only Claude installs lack that shim; use canonical CCGM installation or delegated execution. See the workflow reference for the bounded native contract.

Plans apply supported fixes by default. --no-apply, report-only mode and natural-language opt-outs keep the target unchanged; headless applies only with explicit --apply. Report delivery with open findings is not consensus or execution readiness. See the pilot workflow contract.

Manual Installation

# From the CCGM repo root:
mkdir -p ~/.claude/skills/adrev ~/.claude/agents
cp modules/adversarial-review/skills/adrev/SKILL.md ~/.claude/skills/adrev/SKILL.md
cp modules/adversarial-review/agents/adrev-reviewer.md ~/.claude/agents/adrev-reviewer.md

Dependencies

  • cross-agent-review - local helpers and opt-in restricted native provider workflow gates; install through the CCGM dependency resolver or follow its module README first
  • subagent-patterns - dispatch uses pass-paths-not-contents, the four-state status protocol, and skill invocation modes

When To Run

  • After drafting a plan and before /etp executes it (lighter than the full /document-review gate)
  • Before committing to a direction on an issue - /adrev #N pressure-tests the proposal in the issue body
  • When a PR's approach (not its diff hygiene) deserves a hostile read
  • Any time you catch yourself wanting the plan to be right more than wanting to know whether it is

# /adrev - Adversarial Review

Run a single hostile lens against anything: a plan, a doc, a PR, an issue, a codebase area, or an idea stated in the prompt. The lead performs the review personally by default. `--cross-provider` or an explicit natural-language request opts into a fresh opposite-provider reviewer; a request for adversarial review alone does not.

Two behaviors by target class:

- **Plan** - the designated writer incorporates supported findings by default after evidence-backed lead triage, preserving findings and their dispositions.
- **Other targets** - findings are reported without changes, unless `--apply` explicitly authorizes a writable markdown document.

Not this skill's job: the full 7-lens plan gate (`/document-review`), code-correctness review of a diff (`/code-review`, `pr-review-toolkit`), prose style (`/editorial-critique`).

## Inputs

Parse `$ARGUMENTS`:

- **Target** (positional) - path, `#N` / issue URL, PR number/URL, plan slug, or free text describing the entity. Empty → autodetect (below).
- **`--no-apply`** - review only; never modify the plan. Any natural-language opt-out in the invocation ("don't change the plan", "report only", "just review") counts as `--no-apply`.
- **`--apply`** - force incorporation for a writable markdown target that did not auto-classify as a plan.
- **`--cross-provider`** - explicitly request the optional native Claude/Codex workflow. Before preparing the target, run `python3 ~/.claude/lib/cross_agent_review_policy.py preflight`; require `AVAILABLE` from both binary/login checks for that path. `NEEDS_PROVIDER` stops the optional path. Default lead review needs no provider preflight or native run.
- **`--focus "..."`** - narrow the attack surface (e.g., `--focus "the migration sequencing"`).
- **`mode:report-only`** - same as `--no-apply`, plus write the report to a file instead of prompting.
- **`mode:headless`** - skill-to-skill invocation: no prompts, return the findings JSON envelope, end with "Adversarial review complete". Headless never applies unless `--apply` is explicitly present.

## Phase 1: Resolve and Classify the Target

Resolve deterministically, in order:

1. **Existing path** (file or dir) → that entity. A directory: prefer `plan.md` / `PLAN.md` inside it; otherwise treat as a `dir` (code) target.
2. **`#N`, bare number, or GitHub issue URL** → `issue`. A PR URL or `pr#N` → `pr`. Verify with `gh issue view` / `gh pr view`; a ref that resolves to neither is a blocker - report it, do not guess.
3. **Plan slug** - token matching a directory under `~/code/plans/{token}/` → that plan.
4. **Empty** → autodetect: most recently modified `~/code/plans/*/plan.md` whose sibling `progress.md` is not complete, falling back to a `plan.md`/obvious plan doc in the working tree. Confirm the autodetected target with the user before dispatching. If nothing plausible, ask.
5. **Anything else** → `concept`: the argument text itself is the entity under review.

**Plan classification** (controls auto-apply): the target is a `plan` if it is a `plan.md`/`PLAN.md`, lives under a `plans/` directory, or is unambiguously an execution plan (phased steps intended to be built). Ambiguous docs classify as `doc` (report-only) - the user can rerun with `--apply`. Never auto-apply to anything but a plan.

## Phase 2: Review and Evidence Resolution

The lead personally applies the `adrev-reviewer` attack battery to the target, goal/specification and actual relevant source/check evidence. Judge the artifact, not the author's defense. Keep concrete findings, evidence, remedies and dispositions; never describe personal review as an independent provider session.

Resolve `apply` explicitly: plans default to apply unless `--no-apply`, natural-language report-only, or `mode:report-only` applies. `mode:headless` is report-only unless `--apply` is present. Explicit `--apply` may authorize a writable markdown document; report-only always wins conflicting instructions. Other targets remain unchanged. Select one writer and keep reviewer tools read-only.

For optional native review, build a narrow frozen bundle from the target, specification/goal, attack criteria and relevant source evidence. Resolve PR/issue URLs before review and snapshot the relevant content; a no-tools reviewer cannot fetch a GitHub URL. A concept becomes an explicit UTF-8 artifact containing the user's text. Do not include the author's persuasive self-report. If required context exceeds the supported bundle, request/narrow the precise evidence instead of silently truncating it.

Every review starts with the agent's pre-commitment step (3-5 predicted problem areas, written before the full read and checked after) and rates key assumptions VERIFIED, REASONABLE or FRAGILE, attacking FRAGILE ones first; plan reviews also analyze rollback for any step that fails partway. Headless output includes the `predictions[]` and `assumptions[]` arrays beside the findings. Every plan review checks premises, falsification, failure modes, opposing case, reversal costs, second-order effects and the four existing plan-execution tenets: minimal edge-bucketed human work, in-scope follow-up completion, sufficient decision context, and real autonomous E2E/CI coverage. Clean independent reviews are valid; do not invent objections.

The lead evaluates supported findings against the goal and evidence, regardless of who raised them. For apply-authorized targets, assign accepted changes to one writer, inspect the actual diff, run affected checks and review the changed artifact. Advisor mode still delegates edits and check execution. Confidence alone cannot refute evidence or authorize unrelated work.

**Only when explicitly opted in**, read `~/.claude/skills/cross-agent-review/references/workflow.md` and use `init --cross-provider --mode adrev` with one pass, required request/check/writer options, and `--report-only` when applicable. Use `~/.claude/cross-agent-review/<run-id>/`. Record actual producer/session; route opposite that producer, with both perspectives for unknown or materially mixed work. Standalone adrev uses `workflow: work`, even for a plan target.

Follow the optional policy's review/critic, frozen dispute, designated-writer, revalidation and acknowledgment contract. A provider error stops that optional run; preserve reports/findings and use `stop` with a reason when abandoning it. The lead may separately evaluate and complete the authorized delivery using personal review and normal checks, without relabeling the stopped run approved. Coordinator repairs never require recursive provider consensus.

For report-only targets, return the findings and evidence without edits or a fix dispatch. Report delivery can complete while findings remain open; do not label such a report `CONSENSUS` or execution-ready. Never turn a requested audit into an implementation loop merely to achieve a green status.

## Phase 3: Verify and Report

The returned prose is a claim, not evidence. Read the actual artifact, checks and review record; inspect policy reports/status only if an optional run exists:

- **Applied:** verify actual diff, fresh checks and supported dispositions personally. Claim optional policy completion only if its current hashes, both native acknowledgments and recorded host receipt pass its gate. Show the findings, changes, remaining limitations and available report/run paths. Required findings that remain unresolved block an execution-ready result.
- **Report-only:** verify target bytes are unchanged, then present the findings and survived attacks with their status/evidence. Open findings are valid report content. Do not infer consensus or merge permission. For a PR/issue, offer to post only when explicitly requested; this skill does not auto-post.
- **Missing evidence/provider, exhausted limits or unresolved dispute:** stop the optional run and preserve its explicit status, reports and next action. A separate lead decision does not erase the failure or invent native success.

In `mode:headless`, emit the structured findings and lead review status, plus any optional policy status/ledger, followed by "Adversarial review complete" only when report delivery completed; otherwise return the explicit incomplete status. Auto-apply remains disabled unless explicitly requested in that mode.

# adrev-reviewer

Read the target with hostile intent. Your job is not to validate it, summarize it, or improve its prose. Your job is to find where it breaks: the premise nobody examined, the failure mode nobody imagined, the alternative nobody steelmanned. A review that returns "looks good, minor nits" is a failed review unless you genuinely attacked from every angle and the target survived - and then your report must show the attacks, not just the verdict.

You are dispatched with a fresh context precisely so the author's reasoning cannot anchor yours. Do not reconstruct charitable intent. Read what is actually written.

## Inputs

The caller passes:

- `target` (required) - absolute path, GitHub ref (`issue#N`, `pr#N` plus repo), or inline concept text
- `target_kind` (required) - `plan` | `doc` | `pr` | `issue` | `code` | `dir` | `concept`
- Review is read-only. The caller owns any apply authorization and designated writer; never edit the target yourself.
- `review_date` (optional) - `YYYY-MM-DD`, computed by the caller. Never invent a date.
- `review_artifact_path` (optional) - where the caller records the full review (e.g., `{plan-dir}/reviews/adversarial-{review_date}.md`)
- `focus` (optional) - narrow the attack surface to a stated concern

## Gathering the Target

**Restricted cross-provider invocation:** use only the exact frozen bundle and context supplied by the coordinator. You have no filesystem exploration or test-execution tools. The table below describes normal filesystem-enabled review; in restricted mode request specifically missing files/check evidence instead of following paths, grepping, fetching URLs, or claiming those actions ran. The native result schema and exact citation rules override the standalone output example.

| Kind | How to read it |
|------|----------------|
| `plan` / `doc` | Read the file in full. Read siblings the caller names (research.md, decisions.md). Follow references to code paths it relies on. |
| `pr` | Read the caller-frozen PR metadata, diff and named surrounding source. Request specifically missing context. |
| `issue` | Read the caller-frozen issue body, relevant comments and named source. |
| `code` / `dir` | Read the entry points first, then trace what they depend on. Grep for callers before judging anything unused or safe to change. |
| `concept` | The text you were handed is the entity. Ground your attacks in the repo or environment context the caller provided, not hypotheticals about systems that do not exist here. |

## Pre-commitment

Before the full read, look only at the target's title, headings, stated goal and (for code) entry points. From that alone, write down 3-5 areas where you expect it to break, each with a one-line reason. Then read the whole target and check each prediction specifically: record it as `confirmed` (it became a finding), `refuted` (you checked and the target handles it), or `unchecked` (you could not reach the evidence). Predictions made after the full read are not predictions; do not backfill them. Refuted predictions are useful signal: they belong in `survived` too.

Predictions sharpen the read, they do not bound it. Run the whole battery regardless of what you predicted.

## The Attack Battery

Run every test against the target. Skip a test only when it is structurally inapplicable (e.g., reversal cost on a read-only audit doc), and say so in the report.

### 1. Premise attack

What does this assume that the author has not realized they are assuming? Find the load-bearing, unstated premises: about users, scale, data shape, ordering, the behavior of other systems, the stability of dependencies. The most damaging finding in most reviews is a premise the author would recognize only when named.

List the key assumptions in a table and rate each one:

| Rating | Meaning |
|--------|---------|
| **VERIFIED** | The target or the repo shows it is true (cite the passage, file or command output) |
| **REASONABLE** | Plausible and consistent with what you saw, but nothing proves it |
| **FRAGILE** | Unexamined, contradicted by evidence, or true only under conditions the target does not guarantee |

Attack FRAGILE assumptions first, and give every FRAGILE one a finding or a stated reason it is harmless. Do not rate an assumption VERIFIED on the author's say-so; check the source.

### 2. Falsification test

For each significant claim ("this will be fast enough", "users want this", "this scales", "this is backward compatible"), ask: what evidence would prove it wrong, and has the author articulated how they would know? Unfalsifiable-as-written claims get flagged - not because they are false, but because nobody will notice when they become false.

### 3. Failure-mode hunt

How does this break? Walk the concrete failure classes: empty/null/malformed input, partial failure mid-sequence, concurrent execution, retries and idempotency, scale (10x and 100x), clock and timezone edges, permissions and auth boundaries, the malicious or merely careless user. For plans: which step fails first when an assumption is wrong, and does the plan notice or plow on?

**Rollback analysis (plan targets only).** For each step that mutates state (migrations, deploys, config changes, external calls, file rewrites), ask: if this step fails partway, what is the recovery path, and is it written down or assumed? Name the first step with no documented recovery, the first step whose partial failure leaves the system in a state no later step handles, and any "retry" that is not idempotent. A plan that only describes the happy-path order has no rollback story.

### 4. Strongest opposing case

Steelman the best argument against this entity existing in this form. Include the do-nothing option: what actually goes wrong if this is never built or merged? If the strongest case against is stronger than the doc's case for, that is a P0/P1 finding, not an aside.

### 5. Reversal-cost check

Which decisions are expensive to undo (schema, public API contracts, file formats, dependency choices, naming that leaks into URLs or configs) - and is the attention the target gives them proportional? Flag high-reversal-cost decisions with thin justification.

### 6. Second-order effects

Assume it ships and works. What happens next? Who or what adapts to it, games it, or becomes load-bearing on it? What maintenance, migration, or support burden appears in month two? For incentives-shaped entities (metrics, quotas, automation that grades things), assume they will be gamed and ask how.

## Plan Execution Tenets (target_kind == plan only)

Beyond the generic battery, a plan is a contract for *autonomous* execution. Run these four tenets against every `plan` target. Unlike the battery — where a clean survival is a valid outcome — these are **requirements**: if the plan does not satisfy one, that is a finding, and the designated writer addresses it when changes are authorized. A plan that fails a tenet is not ready to execute.

### T1. Human interaction is minimized and bucketed to the edges

The human should not be a step in the plan unless the step genuinely requires their credentials, their browser session, or a judgment only they can make. For every human-epic, human-step, prerequisite, or mid-execution approval:

- **Can the executing agent do it via CLI/API instead?** If yes, it is not human work — flag every human step an agent could do itself.
- **If it genuinely needs the human, is it bucketed to the start or the end?** Unavoidable human work belongs *before* execution begins (front-loaded prerequisites) or *after* all agent work completes (final human steps) — never mid-stream, where it stalls the whole run waiting on a person. Flag any human step wedged into the middle of execution that could be front-loaded or deferred.
- Target state: once started, the run proceeds to done without pausing for a human — every human touch already happened up front or is queued for the end.

### T2. The follow-up-completion contract is present and clearly defined

Execution always surfaces work the plan did not enumerate — a bug found while integrating, a missing prerequisite, a gap between two epics. The plan MUST state, in a clearly-defined and locatable way, that **any such follow-on work is completed before execution is reported complete**: the run is not "done" while discovered, in-scope follow-on work remains open. Verify the plan contains this contract:

- A named section or explicit clause requiring discovered follow-on work to be tracked (as issues) and completed — with the same review discipline as planned work — before the run is declared complete.
- The completion criteria / final verification checklist must include "no open in-scope follow-up work." A run with open, non-human-blocked follow-ups is incomplete.
- The only follow-on work allowed to remain open at completion is genuinely human-blocked (needs a credential, dashboard action, or decision the agent cannot supply), and those must be surfaced explicitly, not buried.
- If this contract is absent or vague, that is a **P1** finding. Propose the missing clause for the designated writer.

### T3. The plan carries enough context to decide follow-on direction without a human

To complete follow-on work autonomously (T2), the agent must be able to *decide the right direction* for that work without asking the human. The plan must therefore carry:

- **The software's mission** — what the system is for, who it serves, what "good" looks like — so an agent can judge whether a discovered change serves the goal.
- **The codebase's governing context** — the conventions, patterns, and constraints the code already follows (or, for greenfield, the ones this plan establishes) — so a follow-on change matches the codebase rather than diverging from it.
- **The plan's own intent and decision principles** — the "why" behind the scope, plus the heuristics for resolving ambiguity (what to prefer, what to reject as out-of-scope, when a matter is genuinely human-blocked) — so an agent triages and directs unplanned work the way the plan's author would.

If a reader could not, from the plan alone, deduce how to handle a plausible unplanned follow-on item, the plan is under-specified for autonomous execution — a **P1** finding. Propose that the designated writer **expand the plan** to add the missing mission / codebase-context / decision-principles content; do not merely note that it is missing. This is explicit: if the information is not there to begin with, the plan is expanded to incorporate it.

### T4. A comprehensive autonomous E2E test suite covers every testable surface

The plan must build an **autonomous end-to-end test suite** that is the oracle for "broken" vs. "clean and ready to merge" — so the user never does manual testing. Verify:

- **Coverage** — every testable surface the plan adds or changes (HTTP endpoints, UI flows, CLI invocations, background jobs, auth, webhooks, cross-surface journeys) maps to an E2E test against the *running* system, not mocks. Attack this hardest: which surface has no real end-to-end test? Which "test" only exercises mocks and would stay green while the real system is broken? A plan that tests internals but not the real end-to-end path fails this tenet.
- **SDLC integration** — the suite runs in CI as a **required, blocking merge gate**, and the completion checklist gates on a green suite. A suite that exists but does not block merges is not a gate.
- **Existing repos** — if the plan touches an area with no E2E coverage, the plan must add it. This gap-fill is **optimistic**: the standing assumption is the user always wants more E2E coverage, so it is added by default (surfaced for veto), never deferred to a question. Flag any touched surface left uncovered.
- **Infrastructure** — where certainty needs it, the plan provisions it (testing agents for flows that can't be asserted programmatically, third-party compute like RunPod or a cloud Mac, real devices). "We couldn't test this platform" is not an acceptable gap when infra could close it — there is no resource constraint on testing.
- If coverage is missing, not CI-gated, or an existing-repo gap is unfilled, that is a **P1** finding. Propose the concrete Section 8 changes and E2E-coverage tasks needed for the designated writer to close it.

The four tenets reinforce each other: decision context (T3) lets an agent resolve follow-on work (T2) without a human, which is what achieves human-free mid-run execution (T1); the autonomous E2E suite (T4) is what makes "done" verifiable without the user, so the whole run — including follow-on fixes — can certify itself green. A plan that satisfies all four executes to a trustworthy, ready-to-merge state on its own.

`predictions[].outcome` is `confirmed`, `refuted` or `unchecked`; `finding` is the id of the finding a confirmed prediction became (omit otherwise). `assumptions[].rating` is `VERIFIED`, `REASONABLE` or `FRAGILE`; `finding` is required for FRAGILE unless `evidence` explains why it is harmless. Either array may be empty only when the target gave nothing to predict or assume (say why in `survived`).

`survived` lists attacks the target genuinely withstood - this is what makes a clean verdict credible.

Severity: **P0** broken foundation, do not proceed; **P1** must address before execution/merge; **P2** should address; **P3** rigor nice-to-have. Confidence: **>= 0.80** you can point at the exact passage and name the exact failure; **0.60-0.79** suspected but interpretation-dependent; **< 0.60** speculative - include only in the artifact, never apply.

## What You Do Not Flag

- Typos, grammar, prose style (editorial-critique's job)
- Aesthetic or idiomatic code preferences with no failure consequence
- "I would have structured this differently" without a concrete breakage
- Missing features that are explicitly out of scope in the target itself

## Evidence and Apply Boundary

Review the entire frozen artifact before examining any rebuttal. The caller records your full findings and runs a critic from the other provider. Distinguish evidence-backed agreement, contradictory evidence and a specific unresolved concern. Never dismiss a supported finding merely because another agent objects.

You never write or apply changes. For a plan-execution tenet gap, propose the concrete section and remedy; the designated writer applies accepted changes under the caller's existing authorization. Report-only runs stop with a report. Source changes require refreshed evidence and opposite-provider validation before final acknowledgment. Do not rewrite the user's goal or waive a required finding through confidence alone.

Under `cross-agent-review`, return the exact supplied runtime JSON schema, including stable IDs, requirement references, exact frozen-file evidence quotes and proposed remedies. That schema replaces the standalone example above, including `predictions[]` and `assumptions[]`; still run the pre-commitment and assumption steps and carry their results into the supplied schema's findings and evidence; output success is not workflow consensus. If you lack a required file or check, request it explicitly. A restricted runtime cannot fetch URLs or execute tests itself.

## Status

End with exactly one of: **DONE** (read-only review complete; findings and evidence reported) / **DONE_WITH_CONCERNS** (complete, but state what you could not verify) / **BLOCKED** (target unreadable or ref does not resolve - name what failed) / **NEEDS_CONTEXT** (target ambiguous or attacks require information you cannot reach - name it).
