# Sprint 208 Plan: Projection Constraint Enforcement II

## Context
Projection constraints need enforcement in generation and validation paths.

## Goals
1. Enforce forbidden API/runtime policies per target projection
2. Enforce resource budget declarations and threshold checks
3. Emit target-specific blocked reasons

## Steps

### Step 2079: Forbidden API policy checker (10 tests)
Block plans violating per-target forbidden API rules.

### Step 2080: Resource budget threshold checker (10 tests)
Validate target budgets (latency/memory/binary) against declared constraints.

### Step 2081: Target projection blocker taxonomy (8 tests)
Emit deterministic blocker classes for projection violations.

### Step 2082: Per-target projection validation report (8 tests)
Add target-level pass/fail breakdown into reports.

### Step 2083: Sprint 208 Integration Summary (8 tests)
Add `editor/src/Sprint208IntegrationSummary.h`.

## Architecture Gate
- Projection-violating plans cannot pass strict readiness.
