SP8D Protocol Test Harness: Browser Concurrency, Diagnostics & E2E Validation

Protocol Test Scenarios

Interactive, real-world browser concurrency and protocol validation.

1. Live High-Throughput Stress

Scenario: Simulates 5,000 message events between async producer and consumer, measuring actual messages processed and time to completion.
Why It Matters: Legacy postMessage or event bus patterns collapse well below this throughput. Real data science copilots require thousands/sec without UI freezes.

Not run

Duration: - ms Lost: -

Key metric: throughput, no missed/lost messages, no lag.

2. Slot Reclamation & Stale-Job Handling

Scenario: Intentionally abandons some job slots to see if protocol reclaims memory/slots automatically.
Why It Matters: This is vital for long-running browser sessions—leaks or stuck jobs can creep in and kill reliability.

Not run

Reclaimed: -, Errors: - Free slots after: -

Key metric: Reclaimed slot count, protocol recovery visible in logs.

3. Race Condition & Conflict Resolution

Scenario: Multiple producers and consumers hammer the shared channel, purposely colliding on slots.
Why It Matters: Race bugs in message-passing systems are the #1 hidden browser reliability risk. SP8D must resolve conflicts cleanly.

Not run

Produced: -, Consumed: -, Conflicts: -, Errors: -

Key metric: # of resolved conflicts and error count.

4. Protocol Correctness & Data Integrity

Scenario: Sends randomized messages and checks every output for corruption, order, duplicates, or loss.
Why It Matters: Real-world browsers lose/corrupt data under stress if protocol is weak—financial workflows can't tolerate this.

Not run

Sent: -, Received: -

Key metric: end-to-end message correctness, reports first failure.

5. Slot Generation/Cycle Tag Wraparound

Scenario: Repeatedly fills and drains a slot to force the slot generation/cycle tag (Gen/Cycle Byte) to wrap from 255 to 0.
Why It Matters: Ensures protocol correctness and no message loss or corruption even after many cycles, validating the slot generation logic.

Not run

Cycles: -, Errors: -, Final Gen: -, Protocol Error: -

Key metric: No protocol errors, all slots healthy after wraparound.

6. DoS/Flood Resilience

Scenario: Floods the channel with 50,000+ messages as fast as possible, simulating a denial-of-service or buggy producer.
Why It Matters: Validates protocol stability, error handling, and resource usage under extreme load. Ensures no crash, memory leak, or starvation of legitimate consumers.

Not run

Duration: - ms Timeouts: -

Key metric: No crash, no memory leak, no starvation, error count.
