Run log (no narrative digest was archived for this date).

Checked 30 providers (rotating slice: AvaCloud..Triton, TronGrid..thirdweb Insight, plus Alchemy Data APIs/Solana, Allium x2, Allnodes/PublicNode) and the 6 items due within 14 days; swept Sept 12-14 news. Changes: BlockPI docs show a key-free Public RPC tier (10 rps, archive, unlimited RU); Zerion API lists Robinhood Chain; Triton adds Preconfs at $50/1M messages; Allnodes shows 25% annual discount (prior $160 base was a misread of the failover add-on); Alchemy's $0.525/1M CU flat PAYG rate propagated to the Data APIs and Solana rows; Chainlist 43114 now 31 entries. Deadlines: Arbitrum buildathon and Colosseum World's Fair both kicked off with registration still open (start entries replaced by Oct 2 / Oct 12 close entries); ETHOnline ends Sept 16; Summit, Alchemy EIP-7702, Helicon, Moralis unchanged. Official changelogs quiet (Alchemy 9/10, Chainstack 9/11, QuickNode 9/10, Helius 9/05, Moralis 8/26, Ava Labs 9/08, Arbitrum 9/09, Solana 9/08). Unreadable: The Graph Market pricing, TonAPI pricing (JS); TronGrid/UniSat/Unmarshal still unpublished.
