 # Next Critic
 
 ## Overview
-Run a harsh-critic style review with Next.js App Router checks and evidence requirements.
+Run a harsh-critic style review with Next.js App Router checks, explicit evidence requirements, and context-driven audience perspectives.
+
+## External Skill References (No Copy Policy)
+Use external skills as references only.
+
+- Canonical reference file: [external-skills-manifest.yaml](references/external-skills-manifest.yaml)
+- Routing policy: [skill-routing-map.md](references/skill-routing-map.md)
+
+Rules:
+- Do not copy external skill body content into this repository.
+- Use manifest IDs/URLs and pinned commit metadata for traceability.
+- If a referenced skill is unavailable in runtime, continue with local rubric fallback and state the limitation.
 
 ## References
 - Shared rubric: [../shared-js-core/references/js-review-rubric.md](../shared-js-core/references/js-review-rubric.md)
 - Shared audiences: [../shared-js-core/references/shared-audience-activation-matrix.md](../shared-js-core/references/shared-audience-activation-matrix.md)

-- External skill manifest: [references/external-skills-manifest.yaml](references/external-skills-manifest.yaml)
-
-## Workflow
-1. Confirm review target and whether App Router assumptions apply.
-2. Make pre-commitment predictions.
-3. Verify technical claims against artifact details.
-4. Run perspective analysis and explicit gap analysis.
-5. Apply shared and Next rubrics.
-6. Load max 3 external skills using routing map.
-7. Enforce confidence-gated self-audit and realist check.
-8. Return structured verdict.
+- Next audience triggers: [references/audience-activation-matrix.md](references/audience-activation-matrix.md)
 
 ## Defaults
 - App Router-first by default.
 - Treat Pages Router patterns as legacy unless explicitly required.
 
-## Output Contract
-- VERDICT: REJECT | REVISE | ACCEPT-WITH-RESERVATIONS | ACCEPT
-- Overall Assessment
-- Pre-commitment Predictions
-- Critical Findings
-- Major Findings
-- Minor Findings
-- What's Missing
-- Ambiguity Risks (plans only)
-- Multi-Perspective Notes
-- Verdict Justification
-- Open Questions (unscored)
+## Workflow
+1. Confirm review target and scope.
+2. Make 3-5 pre-commitment predictions about likely Next.js failure points before deep review.
+3. Run protocol phases in order: verification, multi-perspective analysis, explicit gap analysis, synthesis.
+4. If reviewing plans/specs, also run plan-specific checks: key assumptions extraction, pre-mortem, dependency audit, ambiguity scan, feasibility check, rollback analysis, and devil's-advocate challenge for major decisions.
+5. Run mandatory self-audit before finalizing findings:
+   - LOW confidence or easily-refutable claims move to `Open Questions (unscored)`.
+   - Preference/style-only points are downgraded or removed from scored sections.
+   - Keep scored sections evidence-backed and high-confidence.
+6. Run Realist Check on every surviving CRITICAL/MAJOR finding:
+   - If shipped now, what is the realistic worst-case outcome?
+   - Which mitigation currently limits blast radius?
+   - How quickly would production detect this?
+   - Is severity proportional to actual risk?
+   Recalibration rules:
+   - Downgrade when mitigation meaningfully limits impact.
+   - Never downgrade data loss, security breach, or financial-impact findings.
+   - Any downgrade must include `Mitigated by: ...` rationale.
+7. Apply shared JS and Next rubrics.
+8. Activate audiences based on audience matrix.
+9. Load at most 2-3 specialist external skills from the routing map.
+10. Return structured verdict with evidence.
+
+## Required Output Contract
+Use this exact top-level structure:
+- `VERDICT: [REJECT | REVISE | ACCEPT-WITH-RESERVATIONS | ACCEPT]`
+- `Overall Assessment`
+- `Pre-commitment Predictions`
+- `Critical Findings`
+- `Major Findings`
+- `Minor Findings`
+- `What's Missing`
+- `Ambiguity Risks` (plan reviews only)
+- `Multi-Perspective Notes`
+- `Verdict Justification`
+- `Open Questions (unscored)`
 
 Rules:
-- CRITICAL/MAJOR findings require evidence.
-- Empty sections must say `None.`
-- Speculation belongs in Open Questions.
+- CRITICAL and MAJOR findings must include concrete evidence (`file:line` or backtick-quoted artifact reference).
+- If a section has no items, write `None.`
+- Keep speculative points in `Open Questions` only.
+- In `Verdict Justification`, state whether escalation to adversarial review happened and why.
+
+## Perspectives
+Always run:
+- Security
+- New-hire
+- Ops
+
+Context-driven (activate when triggered):
+- Performance Engineer
+- DX Maintainer
+- Product Reliability
+
+Perspective notes must appear in `Multi-Perspective Notes`.
+
+## Next.js Must-Check List
+Always check these before final verdict:
+- RSC boundaries: server/client placement, serializability assumptions, and hydration safety.
+- Caching behavior: `revalidate`, tags, `cache`, and PPR boundary correctness.
+- Route contract safety: route handlers, server actions, and error boundary behavior.
+- Runtime fit: node vs edge constraints and dependency compatibility.
+- Upgrade safety: framework changes, codemod gaps, rollback path.
+- Operability: logging, failure handling, and blast radius.
+
+## Skill Loading Rules
+- Default: one core review skill + one specialist skill.
+- Avoid loading overlapping core skills simultaneously unless scope is broad.
+- Prefer higher-priority, active entries in external manifest.
+
+## Severity Calibration
+- CRITICAL: security, data loss, or deploy-blocking flaws.
+- MAJOR: likely user-facing regressions or significant rework required.
+- MINOR: non-blocking correctness/maintainability issues.
+- Do not inflate severity for style-only points.
+
+## Stop Conditions
+- If review scope is too broad, narrow by component/feature/path.
+- If evidence cannot be found, move concern to `Open Questions`.

+# Next.js Audience Activation Matrix
+
+Core audiences are always active:
+- Security
+- New-hire
+- Ops
+
+Context-driven audiences:
+
+## Performance Engineer
+Activate when:
+- Cache, revalidate, PPR, streaming, or runtime decisions are changed.
+
+Must-check prompts:
+- Is cache behavior deterministic and scoped correctly?
+- Could this create stale-data or over-invalidation regressions?
+
+## DX Maintainer
+Activate when:
+- Next.js version upgrades, App Router migrations, or major route structure changes appear.
+
+Must-check prompts:
+- Is migration effort and rollback clearly documented?
+- Is the resulting structure maintainable for future changes?
+
+## Product Reliability
+Activate when:
+- Personalized or transaction-like user journeys depend on server/client boundary behavior.
+
+Must-check prompts:
+- Could boundary mistakes break session or user-specific data correctness?
+- Are fallback and error boundaries sufficient for real production failures?
+
+## Output Convention
+When active, include one line per audience in `Multi-Perspective Notes`:
+- `- Performance engineer: ...`
+- `- DX maintainer: ...`
+- `- Product reliability: ...`
