Why: ctx is not defined on line 369 of useAbilities.ts; referencing ctx.hasPermissionInMetadata when folder is loaded throws a ReferenceError at runtime.

🔴 ReferenceError: ctx is not defined in useIsGrafanaPromRuleEditable

Inside useIsGrafanaPromRuleEditable, ctx is referenced on lines 369 and 370 (ctx.hasPermissionInMetadata(...)), but ctx is neither imported nor declared anywhere in useAbilities.ts or within the hook scope. When a rule and its folder are successfully loaded, executing this hook will throw an unhandled ReferenceError: ctx is not defined.

Suggested change

	const canEditGrafanaRules = ctx.hasPermissionInMetadata(rulesPermissions.update, folder);
	const rulesPermissions = getRulesPermissions('grafana');
	const canEditGrafanaRules = contextSrv.hasPermissionInMetadata(rulesPermissions.update, folder);
	const canRemoveGrafanaRules = contextSrv.hasPermissionInMetadata(rulesPermissions.delete, folder);

Why: Line 369 references an undeclared identifier ctx when evaluating folder permissions for Grafana alert rules, throwing an unhandled ReferenceError at runtime when the hook executes and causing component crashes / denial of service during permission checks.

🟠 ReferenceError due to undeclared ctx in permission check hook

In useIsGrafanaPromRuleEditable, line 369 calls ctx.hasPermissionInMetadata(...). However, ctx is neither imported, defined in the module scope, nor retrieved via a context hook (such as useGrafanaContext or useAccessControl). When a user views Grafana alert rules, attempting to render or evaluate rule edit/delete permissions will throw an unhandled ReferenceError: ctx is not defined, crashing the component and preventing proper permission checks.

Suggested change

	const canEditGrafanaRules = ctx.hasPermissionInMetadata(rulesPermissions.update, folder);
	const { context: ctx } = useGrafana();
	const canEditGrafanaRules = ctx.hasPermissionInMetadata(rulesPermissions.update, folder);
	const canRemoveGrafanaRules = ctx.hasPermissionInMetadata(rulesPermissions.delete, folder);

Why: promResponse.data.groups.at(0)?.rules evaluates to undefined when groups is empty on line 68 of GrafanaGroupLoader.tsx; calling .map on it throws a TypeError at runtime.

🟠 TypeError when mapping over rules of an empty group

On line 68, promResponse.data.groups.at(0)?.rules.map(...) uses optional chaining on at(0). If groups is empty ([]), at(0) returns undefined, causing at(0)?.rules to evaluate to undefined. Because optional chaining is missing before .map, JavaScript attempts to call undefined.map(...), throwing an unhandled TypeError: Cannot read properties of undefined (reading 'map').

Suggested change

	{promResponse.data.groups.at(0)?.rules.map((promRule) => {
	{(promResponse.data.groups.at(0)?.rules ?? []).map((promRule) => {

⚙ ADJUSTED — graph context partial (13 of 14 changed files): 1 of 14 changed files have no symbols in the index; 1 of them is not in that checkout at all (public/app/features/alerting/unified/rule-list/GrafanaRuleLoader.tsx) — this PR's base is older than the indexed revision, so those files were renamed or deleted before it and no re-index can bring them back; there is nothing to fix.
