…(P2-3)
P2-2 Evidence Store üzerine zaman-bazlı decay, stale-prune ve duplicate suppression ekler.
SALT-OKUNUR/yardımcı katman — Evidence Store'u DEĞİŞTİRMEZ (decay read-time hesaplanır,
diske yazılmaz); P2-1 confidence FORMÜLÜ değişmez. Cloud/SQL/LLM/Native/hot-path YOK.
- vehicleLearningDecay.ts (yeni):
* calculateDecayedConfidence/applyDecay: üstel yarı-ömür (weak45/candidate90/strong180 gün);
SAAT-SIÇRAMA GÜVENLİ elapsed=max(0,now-lastSeen) → saat geri giderse negatif decay YOK;
[0,1] clamp; yeni kanıt decay olmaz; firstSeen/lastSeen/observationCount KORUNUR
* isPruneCandidate/pruneCandidates: decay'li confidence<0.20 VE ≥180 gün VE weak/candidate →
prune ADAYI (strong ASLA); fiziksel silmez, pruneCandidate:true işaretler (audit)
* createObservationIdentity: evidenceId|fingerprintHash|ECU|rawResponse-hash|zaman-kovası
* DuplicateObservationCache (bounded 2048 FIFO, RAM-only, O(1)): shouldCount — aynı gözlem
aynı pencerede sayılmaz; farklı araç/ECU/response ayrı; reset/dispose zero-leak
* flat API: shouldCountObservation/resetDuplicateCache/dispose (tekil cache)

Amaç
P2-2 Evidence Store üzerine zaman-bazlı decay + stale-prune + duplicate suppression ekler → eski/tekrar-doğrulanmayan kanıtın güveni zamanla düşer; tek-seferlik/yanlış sinyaller bilgi tabanını şişirmez.

Hiçbiri — tamamen additive, salt-okunur.
Decay formülü
decayed = clamp01( confidence · 0.5^(elapsedDays / halfLife) )elapsedDays = max(0, now − lastSeen) / gün→ sistem saati geriye giderse negatif decay yok (CLAUDE.md Clock Jump Protection). Yeni kanıt (elapsed=0) → decay yok. [0,1] clamp; 0 altına inmez.firstSeen/lastSeen/observationCountkorunur.Prune kuralları
Prune adayı (fiziksel silme değil —
pruneCandidate:trueişaretler, audit):Duplicate identity modeli
createObservationIdentity=evidenceId | fingerprintHash | ECU(normalize) | rawResponse-hash(FNV-1a) | zaman-kovası(60s).DuplicateObservationCache: bounded 2048 FIFO, RAM-only (yeniden başlatmada sıfırlanır), O(1) lookup, reset/dispose zero-leak.API

✓ yeni kanıt decay yok · ✓ 90 gün sonra azalır · ✓ strong yavaş/weak hızlı · ✓ 180+ gün zayıf prune-candidate · ✓ strong prune edilmez · ✓ saat-geri negatif yok · ✓ [0,1] clamp · ✓ firstSeen/lastSeen sabit · ✓ aynı gözlem duplicate sayılmaz · ✓ farklı araç/ECU/response/pencere ayrı · ✓ bounded FIFO · ✓ reset/dispose · ✓ girdi mutate edilmez · ✓ boş/bozuk fail-soft.
Risk analizi
Düşük — additive + salt-okunur. Katman çökse bile OBD/Discovery/Fingerprint/Auto Learning/Evidence Store/VKB/Manufacturer Intelligence/Diagnostic aynen sürer (her fonksiyon fail-soft). Girdi mutate edilmez; hot-path yok; O(1) + bounded cache; zero-leak dispose. Dokunulmadı: native OBD · poll · Discovery Pipeline · Fingerprint · Auto Learning · VKB · Manufacturer Intelligence · Diagnostic · Evidence Store davranışı · PID/DID registry · SQL/Supabase · cloud · LLM · PR #11/#20.
