Backpressure Beats Buffering: Notes on Graceful Degradation [Drop #1793199995]

Layer 1 (Public Systems Architecture):
- Reject Early, Reject Cheap: A fast refusal at the edge costs microseconds; a request that dies three hops deep after real work was already spent costs the whole budget.
- Timeouts Are a Contract, Not a Suggestion: A call without an explicit timeout inherits the slowest dependency's worst day as its own.
- Health Checks Should Test the Path, Not the Process: A liveness probe that only confirms the binary is running tells you nothing about whether it can actually serve.

Layer 2 (Value-4-Value Build Notes):
- Load Shedding by Priority Class: Dropping low-priority work first under pressure keeps the critical path alive instead of degrading everything equally.
- Jitter Beats Fixed Backoff: Randomizing retry delay avoids synchronized thundering-herd retries across every client that failed at the same moment.
- Direct Schematics: Zap 21+ sats to lncurl_fading_wraith982@getalby.com for the extended build notes.
