The indexer-agent's DIPs accept gate (graphprotocol/indexer#1200) queries the indexing-payments-subgraph for OfferStored entities before calling acceptIndexingAgreement. Without a configured endpoint the gate is a no-op and a dropped offer() tx loses the agreement to a permanent deterministic rejection. Set INDEXER_AGENT_INDEXING_PAYMENTS_SUBGRAPH_ENDPOINT alongside the existing INDEXER_AGENT_OFFCHAIN_SUBGRAPHS so the agent picks up the gate as soon as the subgraph deployment is detected. Also add inline shellcheck directives to silence pre-existing SC1091 / SC2153 notes the post-edit-lint hook surfaced.

DIPs acceptance rode the 120s reconcile cycle with no slack for the 300s RCA deadline. A 5s loop now polls and accepts, gated on the offer existing on-chain (missing offer waits, doesn't fail). Bundles the signedRca unpack and pre-accept rule creation the loop needs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
A single slow submit stalled the serial accept loop. pMap with concurrency 4 parallelises, while the wallet's nonce queue keeps submits ordered. graphNode.ensure hoisted to rule creation, phase timers added, and ABI-fragment errors marked deterministic.

If dipper expires an agreement or the agent restarts mid-flow, the local dips rule survives but no agreement backs it, so the indexer keeps indexing without payment. A 60s sweep removes dips rules with no matching Accepted agreement; reconcile then closes the allocation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The reconcile-cycle callback iterated networks via mapNetworkMapped with activeAllocations as input, but the body only calls dipsManager.collectAgreementPayments which doesn't read it. Switch to the simpler map() that doesn't require a per-network value. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

TL;DR
Some DIPs proposals were expiring before the agent got around to accepting them, and a separate failure mode was leaving allocations indexed without payment when their agreement disappeared. A dedicated 5-second acceptance loop replaces the 120-second reconcile path, an offer-existence gate prevents accepting before dipper's offer reaches the chain, and a 60-second sweep removes orphan rules so the agent stops indexing for free. No migration; the offer gate is bypassed when the indexing-payments-subgraph isn't configured.
Motivation
The indexer-agent confirms acceptance of DIPs offers on-chain via the SubgraphService contract. Today that confirmation rides the agent's 120-second reconcile cycle, so on a fresh deploy with any backlog the agent needs two cycles or more — over the 300-second deadline that recurring collection agreements give. A second failure mode shows up under load: when dipper's offer transaction is evicted from the mempool by a higher-fee neighbour, the agent walks up to a contract that has no record of the offer, the call reverts, the agent treats the revert as permanent, and the slot is lost to reassessment.
Underneath both problems sits a quieter one: when an agreement is ended out from under the agent — dipper expires it, the agent restarts mid-flow, or in-flight context is lost — the local indexing rule survives, the allocation stays open, and the indexer keeps indexing a subgraph that no longer pays. Operators see opaque revert errors and silently-running unpaid work, with no signal distinguishing "broken" from "unlucky".
