- LSPMessageValidator: JSON-RPC 2.0 shape validation (method, id type, params type) - LSPCapabilityNegotiator: per-source capability tracking; shouldRoute gates on declared caps - LSPRequestThrottler: per-URI/method debounce; blocks rapid didChange floods - LSPErrorRecovery: per-source health tracking; stale-cache fallback when crashed - Sprint278IntegrationSummary: poly-parse (C++ + Haskell) end-to-end integration 26/26 tests passing (5+5+5+5+6). All new headers well under 600 lines. LoRA recorded: sprint278-2026-03-01 (9 calls, 6437 tokens). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

// Step 1920: LSPRequestThrottler
|
|
// Debounces per-URI requests to prevent flooding language servers.
|
|
//
|
|
// t1: no prior record → shouldAllow true
|
|
// t2: within debounce window → shouldAllow false
|
|
// t3: after debounce window expires → shouldAllow true
|
|
// t4: reset clears uri; resetAll clears everything
|
|
// t5: lastTimestamp returns -1 for missing, correct value after record
