Move fetch rate-limiting out of utils into a dedicated fetch.ts and make it adaptive: runs at full speed by default, throttling only when an endpoint actually rate-limits it. - per-endpoint AIMD concurrency cap (default 5; halves to 1 on a 429, ramps back on sustained success) — collapses a 429 storm into one patient retry - per-(endpoint,method) rate pacer: paces only when the server gives an explicit reset window (Retry-After/RateLimit-Reset); header-less 429s (e.g. Solana) use jittered exponential backoff instead - standard + de-facto rate-limit header parsing (Retry-After, RateLimit-*, X-RateLimit-*, Solana x-ratelimit-method-*) - web fetch-contract semantics (returns non-ok responses, throws only on network/abort); per-endpoint state shared across instances Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Wire the default rate-limited fetch into every fromUrl constructor, with a ctx.fetch opt-out: a caller-supplied fetch is used verbatim (unwrapped). - ChainContext.fetch opt-out - EVM via ethers FetchRequest adapter; Solana via ConnectionConfig.fetch; Sui via JsonRpcHTTPTransport - TON + Canton via shared createAxiosFetchAdapter (Canton only when ctx.fetch is given, preserving its native HTTP/2 default) - Aptos custom Client shim, applied in fromUrl/fromAptosConfig only (never fromProvider) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Detect "block range too large" RPC errors (Alchemy/Infura/QuickNode/erpc and a generic block-range matcher), learn the max range per endpoint, and transparently re-chunk — removing the need for the manual --page CLI flag. - CCIPLogRangeTooLargeError + parseLogRangeError (extracts max/suggested range) - per-endpoint learned range shared across getLogs calls - remove ccip-cli --page option (LogFilter.page kept as an optional override) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…ecovery hint
endpointKey() now wraps new URL() in try/catch so block tags ('safe', 'latest')
and other non-URL strings don't throw when passed as endpoint identifiers.
Adds missing DEFAULT_RECOVERY_HINTS entry for LOG_RANGE_TOO_LARGE — the
recovery.ts exhaustiveness check was failing CI.
