hermes - 💡(How to fix) Fix [Bug]: Kanban dashboard crashes - plugin SDK missing authedFetch/buildWsUrl after commit a6e47314f

Bug: Kanban dashboard crashes due to missing plugin SDK properties

What happened

The kanban dashboard tab at /kanban crashes with JavaScript errors. The frontend bundle was updated in commit a6e47314f to use SDK.authedFetch and SDK.buildWsUrl, but these properties are not present in the built plugin SDK served to the browser.

Root cause

Commit a6e47314f ("fix(dashboard): sanction plugin WS/upload auth via SDK helpers (gated mode)") added new properties to window.__HERMES_PLUGIN_SDK__ in web/src/plugins/registry.ts:

• authedFetch
• buildWsUrl
• buildWsAuthParam
• sdkVersion

The TypeScript source includes these, but the production build in hermes_cli/web_dist/ was not regenerated. The built bundle still has the old SDK without these properties.

Evidence

• window.__HERMES_PLUGIN_SDK__ in browser only has: React, api, components, fetchJSON, hooks, useI18n, utils
• Missing: authedFetch, buildWsUrl, buildWsAuthParam, sdkVersion
• Source code clearly adds these at lines 133-141 in web/src/plugins/registry.ts
• Built bundle in web_dist/assets/ doesn't contain these symbols

Reproduction steps

1. Update to Hermes v0.15.1 (2026.5.29) or later
2. Navigate to http://localhost:9119/kanban
3. Page crashes with JS errors (uncaught exception)

Expected behavior

The kanban dashboard renders normally, using the SDK auth helpers for API calls.

Actual behavior

The kanban plugin frontend tries to call SDK.authedFetch and SDK.buildWsUrl which are undefined, causing the dashboard to crash.

Workaround

Use the CLI instead:

hermes kanban list --tenant <board>
hermes kanban show <task_id>
hermes kanban create "title" --tenant <board>

Fix

Rebuild the web assets with npm run build in the web/ directory and update the built bundle in hermes_cli/web_dist/.

Environment

• Hermes Agent v0.15.1 (2026.5.29)
