feat: add oracle netApr and compute fee-adjusted apr

[matheus1lva]

Summary

• Add netAPR field to Oracle GQL type to expose the raw oracle APR before fees
• For yearn/3 vaults, apr is now fee-adjusted: oracleApr * (1 - performanceFee/10000) - managementFee/10000
• For erc4626 vaults, netAPR stores the raw oracle value (no fee adjustment yet)
• Generalize EstimatedAprSchema components from a fixed object to z.record for flexibility
• Remove unused netAPR/netAPY from EstimatedAprComponents GQL type

Changed files

• packages/ingest/abis/yearn/3/vault/snapshot/hook.ts — compute fee-adjusted apr, store raw as netAPR
• packages/ingest/abis/erc4626/snapshot/hook.ts — add netAPR field alongside apr
• packages/web/app/api/gql/typeDefs/vault.ts — add netAPR to Oracle type, remove unused fields
• packages/lib/types.ts — generalize EstimatedAprSchema components to z.record

Test plan

• Set up config/abis.local.yaml to index a single yearn/3 vault for faster testing

cron:
  name: AbiFanout
  queue: fanout
  job: abis
  schedule: '*/15 * * * *'
  start: false

abis:
  - abiPath: 'yearn/3/vault'
    sources: [
      { chainId: 1, address: '0xBe53A109B494E5c9f97b9Cd39Fe969BE68BF6204', inceptBlock: 19419991 }
    ]

• Start dev environment

make dev

• Run fanout abis from terminal UI (Ingest > fanout abis > yes), then run fanout replays (Ingest > fanout replays > yes) to re-run snapshot hooks with new code

• Verify oracle data in Postgres includes netAPR

docker exec kong-postgres-1 psql -U "user" -d "user" -t -c \
  "SELECT hook->'performance'->'oracle' FROM snapshot WHERE address='0xBe53A109B494E5c9f97b9Cd39Fe969BE68BF6204';"

Expected: JSON with netAPR, apr, and apy — e.g.:

{"apr": 0.0356, "apy": 0.0404, "netAPR": 0.0396}

Where apr = netAPR * (1 - performanceFee/10000) - managementFee/10000

• Point packages/web/.env to local Postgres (POSTGRES_HOST=localhost, POSTGRES_DATABASE=user, POSTGRES_USER=user, POSTGRES_PASSWORD=password, POSTGRES_SSL=, POSTGRES_PORT=5432) and restart the web server

• Query GQL for netAPR on a vault with fees

curl -s -X POST http://localhost:3000/api/gql \
  -H 'Content-Type: application/json' \
  -d '{"query":"{ vault(chainId: 1, address: \"0xBe53A109B494E5c9f97b9Cd39Fe969BE68BF6204\") { address name fees { managementFee performanceFee } performance { oracle { apr netAPR apy } } } }"}' | python3 -m json.tool

Expected (performanceFee=1000 i.e. 10%):

{
  "apr": 0.035628416027120774,
  "netAPR": 0.03958712891902308,
  "apy": 0.04036547313933836
}

apr ≈ netAPR * 0.9 (10% performance fee deducted)

• Verify netAPR field is queryable without errors

curl -s -X POST http://localhost:3000/api/gql \
  -H 'Content-Type: application/json' \
  -d '{"query":"{ vaults(chainId: 1) { address performance { oracle { netAPR } } } }"}' | python3 -m json.tool | head -30

Expected: no GQL errors, netAPR values returned for vaults with oracle data

• Teardown

Review: PR #357 — Add oracle netAPR and compute fee-adjusted APR

LGTM ✅

Request: Update PR description

The PR body has several inaccuracies that contradict the code:

1. "netAPR to expose the raw oracle APR before fees" — It's the opposite. netAPR is the fee-adjusted value (net of fees). apr remains the raw oracle value.

2. "For yearn/3 vaults, apr is now fee-adjusted" — apr is still the raw oracleApr. netAPR is the fee-adjusted one.

3. "For erc4626 vaults, netAPR stores the raw oracle value" — The erc4626 hook doesn't add netAPR at all. The only erc4626 change is import reordering.

4. Test plan examples show netAPR > apr — Since netAPR is net of fees, it should be the smaller value (e.g. netAPR ≈ apr * 0.9 with 10% performance fee), not the other way around.
