…nc fixes Overhauls the watcher's KEL synchronization to be self-reliant rather than purely reactive to external queries. Key changes: - Fix update_local_kel to compare local SN against witness-reported KSN instead of relying solely on escrow state, preventing cases where KSN was accepted but full KEL events were never fetched - Add WitnessPoller for background polling of tracked AIDs with adaptive intervals (recently active AIDs polled more frequently, stable ones less) and AID subscription support for priority polling - Replace fire-and-forget channel with completion-signaling mechanism so Logs queries await KEL updates (10s timeout) before responding, eliminating the need for external retry loops - Add WitnessHealthTracker recording per-witness response statistics (success/failure counts, response times, consecutive failures) and expose GET /health endpoint for monitoring - Range-based KEL fetching to avoid re-downloading the entire event log - Propagate and log witness query errors instead of silently discarding
When a remote endpoint returns a non-success status with an empty body,
serde_json::from_str("") would fail with "EOF while parsing a value",
producing a misleading "network error" message. Now checks for empty
bodies first and returns a clear error with the HTTP status code.
Also changed JSON parse error fallback to use UnknownError(body) instead
of NetworkError(serde_err) since the raw body is more useful for debugging.
reqwest::Client was using defaults with no timeouts, causing requests to hang indefinitely when endpoints are slow or unreachable. Added 10s connect timeout and 30s overall request timeout via a shared http_client() builder.
Watcher's TEL transport used reqwest::Client with no timeouts, causing requests to witnesses to hang indefinitely when unreachable. Added 10s connect timeout and 30s request timeout, consistent with keri-core transport layer.
forward_query_from iterated witnesses sequentially, so a slow or unreachable first witness would delay fetching events from all others. Now uses join_all() to query all witnesses concurrently (consistent with query_state) and processes all successful responses, improving latency for multi-witness AIDs.
before moving fully to keri sdk we need to keep them available
Add standalone keri_keyprovider crate with pluggable signing backends: - Software: in-memory Ed25519/secp256k1 keys - File-encrypted: Argon2id + XChaCha20-Poly1305 encrypted key files - OS-keychain: platform-native credential store (macOS/Windows/Linux) Introduce SigningBackend trait in keriox_sdk that abstracts the signing interface, allowing Arc<Signer> or Arc<dyn KeyProvider> interchangeably. Refactor operations.rs, signing.rs, and tel.rs to use the generic trait, preserving full backward compatibility with existing Arc<Signer> callers
