# Bead bf-32n: Add bounds enforcement tests
## Status
**Already complete** - The required test `TestAdaptiveRateLimiter_BasicBounds` already exists and passes all acceptance criteria.
## Verification
All acceptance criteria met:
1. ✅ TestAdaptiveRateLimiter_BasicBounds test function exists (line 982)
2. ✅ Table-driven with multiple bound scenarios (4 test cases)
3. ✅ Tests use injected window duration (testWindow = 10ms, no sleep calls)
4. ✅ Tests verify rate stays in [minRate, maxRate] under all conditions
5. ✅ Tests pass: `go test ./proxy -v -run TestAdaptiveRateLimiter_BasicBounds`
## Scope Coverage
All required scenarios covered:
- ✅ Rate never drops below minRate (default: 10)
- ✅ Rate never exceeds maxRate (default: 100)
- ✅ Heavy 429 load drives rate to min but not below
- ✅ Continuous success drives rate to max but not above
## Original Implementation
Test was added in commit 88358f9 ("test(ratelimiter): add basic state and bounds tests for AdaptiveRateLimiter") and improved in commit 22644ea to use injected window duration for faster test execution.
