[BUG] Full-flow selector executes disabled rules by bypassing rule enabled filtering #7978

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

With continued=true and a full-flow selector, AbstractShenyuPlugin takes the last rule in the list and invokes doExecute directly. It bypasses filterRule, including the rule enabled check. A disabled rule is therefore still executable.

Expected Behavior

Disabled rules must not execute. Preserve the intended full-flow selection semantics among eligible rules, and call the plugin's no-rule handler when no enabled rule remains. This issue does not prescribe changing whether full-flow rules evaluate conditions or changing their ordering.

Steps To Reproduce

1. Enable a concrete test plugin extending AbstractShenyuPlugin.
2. Add an enabled selector with type=FULL_FLOW (0), continued=true.
3. Add one rule under it with enabled=false and any valid condition list.
4. Execute a request using execute(...).block().
5. Observed: doExecute receives the disabled rule. Expected: it must not execute that rule.

Reproduced result from the recording test plugin: full:disabled.

Anything else?

• Full-flow branch:

  shenyu/shenyu-plugin/shenyu-plugin-base/src/main/java/org/apache/shenyu/plugin/base/AbstractShenyuPlugin.java

  Lines 110 to 115 in 862f5e3

  	return handleRuleIfNull(pluginName, exchange, chain);
  	}
  	if (selectorData.getType() == SelectorTypeEnum.FULL_FLOW.getCode()) {
  	//get last
  	RuleData rule = rules.get(rules.size() - 1);
  	printLog(rule, pluginName);

• Enabled filter used by the ordinary branch:

  shenyu/shenyu-plugin/shenyu-plugin-base/src/main/java/org/apache/shenyu/plugin/base/AbstractShenyuPlugin.java

  Lines 286 to 288 in 862f5e3

  	private Boolean filterRule(final RuleData ruleData, final ServerWebExchange exchange) {
  	return ruleData.getEnabled() && MatchStrategyFactory.match(ruleData.getMatchMode(), ruleData.getConditionDataList(), exchange);
  	}

Environment

ShenYu master, 2.7.2-SNAPSHOT, commit 862f5e37e894bd8cef85ef540a8629f313e9ecdf, Java 17.

Validation

Reproduced with a minimal concrete AbstractShenyuPlugin subclass, real BaseDataCache/MatchDataCache, Spring MockServerWebExchange and execute(...).block(). The subclass records selector/rule IDs in doExecute. Match caches use the default enabled settings. The existing 90 targeted matching/cache/predicate tests passed; this does not exercise a deployed HTTP gateway.
