sent 1,259,388.6891 AVAX into the consolidation at 18:47:03 UTC on 9 Jun 2026; it held 483,923.9955 AVAX at 16 Sep 2026, and that refill is six payments and nothing else, all six payers the six C-Chain vaults of the batch. The refill is no longer a separate question at 0.35: it is accounted to the unit and carries this row's grade
Evidence: scratch/hunt/blue/coinbase-custody.md: class A into the consolidation, class C on the December sum, class D on NodeID-4gp6z23DrgtRKN3Z8PEmac7drgVxHmdQR, the node this wallet's P key staked from Oct 2025 to Apr 2026 and AVAT's treasury key used from 17 Jul to 6 Aug 2026; platform.getCurrentValidators returns no validator on that node at the 16 Sep 2026 read. The refill: scratch/hunt/blue2/batch-counterparts.md section 4 and deposit-provenance.md section 4 read every inbound row and find six, all from the six vaults, including P-avax1gd8jekz's 100,068.3557 AVAX on 2 Jul 2026 and P-avax1j9tgjlu's 146,175.6398 AVAX on 3 Aug 2026, which is where the 245,623 AVAX left by the two keys that stopped validating went.

Node continuity, evidence class D, is weak on its own here and the row does not rest on it. MEASURED: one private key unrelated to either company, P-avax1qtrykwgqkpj8c9wl93cymu6q9ffssyyu95q8wp, has delegated to NodeID-DVh35F3R11HAAxzeSTbk3eR9w2BzPrJQt since 2022-01-01 21:17:23 and to NodeID-3kUUeZB7umtaENekUfWxa1bxrAU2eq1AD since 2021-09-29 20:48:15, years before Avalanche Treasury Corp existed, and its automation re-delegated 130,455.60 AVAX twice on 2026-08-06 at a 100 percent fee that pays it nothing. These are rented commercial validators, so any node must be age-checked before its overlap is printed as corroboration (scratch/hunt/blue2/delegator-sweep.md section 5). The same read withdraws the claim that a 100 percent fee means no third party can delegate: that node reports delegatorCount 2 and delegatorWeight 260,911.20 AVAX. Re-run: POST https://avalanche-p-chain-rpc.publicnode.com platform.getCurrentValidators with the nodeID, then platform.getTx on the delegation's consumed UTXOs back through the key's own history.
