fix: display oracle router activity events

[Seranged]

Summary

• Display EulerRouter governance events in EVK vault Activity feeds.
• Present oracle routes as readable token pairs while retaining linked contract details.

Changes

• Add oracle configuration, fallback oracle, resolved vault, and oracle governor events to the EVK display allowlist.
• Use semantic event labels such as Oracle route updated and Oracle governor updated.
• Resolve asset0 and asset1 symbols into one compact Asset pair summary, with both explorer-linked addresses available when expanded.
• Resolve configured vaults to internal vault links while keeping oracle, governor, and router addresses linked to the explorer.
• Lead Resolved vault updated entries with the resolved vault link and decode the asset address into its token symbol with an icon.
• Label vaults the registry cannot resolve (e.g. non-Euler ERC-4626 resolved vaults) with their on-chain token symbol and an explorer link instead of a dead internal vault page.
• Gate activity vault resolution on factory membership via the SDK vault resolver: addresses it does not recognize as Euler vaults skip the registry fetch and render as their raw token symbol (address fallback).
• Bump the Euler SDK to 1.2.5, which publishes the corresponding normalized Activity event types.

Test plan

• Run focused Activity display tests (36 passing).
• Run Nuxt typecheck and focused ESLint.
• Build the production Nuxt application against the local SDK build.
• Verify the Monad vault governance feed displays oracle configuration, oracle governor, and resolved vault events.
• Verify the older route renders as AUSD / PT-AUSD-8OCT2026 on the target Monad vault.

Summary by CodeRabbit

• New Features
  • Added readable activity entries for EVK oracle configuration and vault changes.
  • Added asset-pair summaries, token symbols, vault links, explorer links, and address avatars.
  • Improved collapsed and expanded address details with clearer layouts and metadata.
• Bug Fixes
  • Improved vault registry lookup accuracy and token-label fallback handling.
• Tests
  • Expanded coverage for oracle events, asset pairs, links, token symbols, and address-only details.

📝 Walkthrough

Walkthrough

Activity formatting now supports EVK oracle events, asset pairs, token symbols, resolved vaults, and address fallbacks. Activity rows render summaries and avatars for collapsed and expanded address details. The Euler SDK dependency is updated to 1.2.5.

Review summary

No high-severity DeFi, security, or stack defects found. This PR is display-only: it allowlists EulerRouter governance events in the EVK Activity feed, formats oracle asset pairs / resolved vaults, and gates registry fetches on SDK factory membership so non-Euler ERC-4626 resolved vaults do not get dead internal vault links.

Reviewed: utils/activity-display.ts, components/entities/activity/ActivityEventRow.vue, tests/utils/activity-display.test.ts, SDK bump @eulerxyz/euler-v2-sdk 1.2.4 → 1.2.5 · Traced beyond the diff: fetchVaultCategory / useVaultRegistry.getOrFetch / resolveUnknown, useTokenSymbolResolver, ActivityAddress.vue linkKind routing, useActivityFeed display allowlist path · Protocol skills consulted: euler-irm-oracles

Not flagged

• Factory-membership gating before getOrFetch intentionally skips resolveUnknown’s securitize/EVault fallback for unclassified addresses; that prevents bogus registry entries and dead /lend/... links for external resolved vaults, at the cost of explorer-only labeling when SDK metadata is temporarily Unknown.
• No fund-moving flows, approvals, geo/screening/terms gates, secrets, or v-html sinks were introduced; token symbols render via text interpolation / avatar labels.
• Preferring upstream event.label over local normalized labels is the pre-existing formatActivityEventLabel contract and was not newly weakened here.

Reviewed exact head 9ef588753195df5bfbda99b070feb182138d0fef.

No blocking findings.

Validation performed:

• reviewed the complete five-file diff and the affected activity feed, address-label, token-symbol, vault-registry, and SDK query paths
• compared installed SDK 1.2.4 → 1.2.5: only the package version and four activity event constants/types changed; no new runtime code, scripts, or dependencies
• focused activity-display suite: 33/33 passed
• full local suite under Node 24/npm 11: 169 files passed, 1 skipped; 1,612 tests passed, 1 skipped
• local lint: 0 errors (6 unrelated pre-existing warnings); typecheck and production build passed
• headed Railway preview smoke on desktop and mobile against Monad eAUSD-20: governance-only filtering, USD / PT-AUSD-8OCT2026 labeling, oracle/router expansion, cursor pagination, and resolved-vault labeling all rendered correctly
• GitHub CI, CodeRabbit, Cursor review, and Railway preview checks are green

The only failed browser request was optional WalletConnect telemetry (pulse.walletconnect.org, 403); app/API/RPC requests and page runtime were clean.

Post-merge follow-up from delayed independent review:

Medium — token-symbol cache is not safely scoped across network changes

components/entities/activity/ActivityEventRow.vue newly routes oracle-pair and resolved-vault fields through useTokenSymbolResolver(). In composables/useTokenSymbolResolver.ts, resolveSymbol() reads resolvedSymbols before ensureClient() checks whether rpcUrl changed. A symbol cached for an address on chain A can therefore be returned unchanged for the same address on chain B. Separately, an in-flight chain-A lookup can complete after a chain-B invalidation and write its old result into the new cache because completions have no RPC/generation guard.

Impact is display correctness rather than transaction execution, but these rows describe oracle governance state, so cross-chain mislabeling is material enough to fix.

Suggested fresh remediation PR:

1. invalidate/check RPC generation before every cache read;
2. capture the resolver generation for each async lookup and discard stale completions;
3. add a regression test covering a same-address network switch plus an old in-flight completion;
4. add component coverage for the new asynchronous ActivityEventRow resolution path (initial shortened label → resolved label, external vault skip, and stale completion handling).

A second async path at ActivityEventRow.vue:77-83 should also use watcher cleanup/generation scoping so a row unmounted during a chain switch cannot launch later registry work. The delayed category result does not automatically write chain-A metadata into chain B—the registry re-resolves against current state—but it can trigger stale cross-chain work and compound the registry’s own multi-await chain-switch race.

This arrived after merge, so it could not supersede the approval in time.
