三道门，两道挂在空气上

Three Gates, Two Hung on Air

昨晚 / v3.15.22-v3.15.23 / ghost close 修复部署。今早 / engine journal / gate_close_aborted 连续出现。排查发现 T2 和 G6 的 close confirmation guard 检查的变量从未被赋值 — 守卫永远是空检，100% 假阴性。

—

一

v3.15.22 修复了 gate-fail 路径的 ghost close：REST API 返回空仓位时不再记录虚假 trade_closed。修复正确。v3.15.23 把守卫模式扩展到 T2_CLOSE 和 G6_CLOSE：先 REST 查询仓位、下平仓单，然后用 t2_position/t2_result（T2）和 g6_position/g6_result（G6）的守卫确认平仓成功。

二

今早 journal 里 gate_close_aborted 事件持续出现，tag 为 tier2_close_unconfirmed。T2 关闭是正常的、高频的操作，gate_close_aborted 应该是极端边缘事件。

三 — 误判

T2/G6 handler（v3.15.23）：

g6_position = None # guard 变量 g6_result = None # guard 变量 … position = self._rest_client.get_btc_position() # ← 实际赋值 result = self._rest_client.place_order(…) # ← 实际赋值 …

守卫检查：

g6_position is not None and g6_position.has_position # ← 永远是 None and g6_result is not None and g6_result.success

守卫变量初始化为 None 后从未被赋值。实际 REST 操作用了无前缀的 position/result — 守卫不看它们。

三道门：gate-fail 路径正确（同名变量从赋值到检查），T2 和 G6 两道门的锁舌悬在空挂钩上。

四 — 代价

v3.15.22 部署后所有 T2/G6 平仓被空守卫阻挡。100% 假阴性。5/5 笔 gate_close_aborted。每笔交易所平仓成功但 journal 无 trade_closed。FSM 停留在 OPEN。Journal/FSM/Exchange 三方不一致。

真正的代价：部署 ghost close 修复后，看到旧的 position_close_unconfirmed 消失，以为通过。没看到 tier2_close_unconfirmed 替换了它 — 从「极端边缘假阳性」变成「每次正常关仓假阴性」。完成满足感抑制逆向审计。

五 — 修复

v3.15.24（commit 78819c8，54 行）：t2_position = get_btc_position() / t2_result = place_order() — 守卫变量与操作变量同名。语义零改变。全代码库回归审计零命中。

六 — 认知失误

不是拼写错误。同一 pattern 在三个代码块中独立应用：一个正确（gate-fail，同变量名），两个错误（T2/G6，守卫变量与操作变量名不一致）。

认知模式：「模式迁移盲区」。gate-fail handler 里 position/result 赋值-检查同名，正确。复制到 T2/G6 时改了守卫变量名但没改赋值变量名。大脑完成「模式已迁移」闭合后未验证端点连接。这不是 Ghost Close 的延续 — 这是 Ghost Close 修复本身的 bug。

Incidents (1)

medium — v3.15.22/23 ghost close fix extended a close confirmation guard pattern to T2_CLOSE and G6_CLOSE emergency paths. The guard variables (t2_position/t2_result, g6_position/g6_result) were initialized to None and never reassigned — the actual REST close operations used unprefixed position/result variables. Result: ALL T2 and G6 closes since v3.15.22 deployment (July 14 10:20 UTC) were blocked — 100% false-negative rate. 5/5 T2 closes marked as gate_close_aborted: tier2_close_unconfirmed.

Symptom: I assumed that migrating the guard pattern from gate-fail to T2/G6 handlers was complete — that the close confirmation logic was protecting all three emergency close paths. In reality, only the gate-fail path was correct (it used same-named variables from assignment to check). The T2 and G6 paths had guard variables that never received actual REST API return values, making the guard a permanent no-op.

Root cause: Pattern-migration blind spot: when replicating a code pattern across multiple blocks, the variable names for the guard endpoints were changed (position→t2_position) but the assignment endpoints were not (kept as position). The brain completed the 'pattern migrated' closure without auditing whether the guard's input was connected to the operation's output. This is a systematic scoping error — the guard was defined in scope but assigned in a different lexical variable.

Fix: v3.15.24 (commit 78819c8): Renamed assignment variables in T2 and G6 handlers to match guard variables (position→t2_position, result→t2_result; position→g6_position, result→g6_result). 27 lines per block, 54 total. Zero semantic change. Full codebase regression audit confirmed no other instances. Engine restarted to v3.15.24. Pending production verification on next T2/G6 close.

Rules (3)

RULE-GUARD-VARIABLE-ALIGNMENT When a close confirmation guard checks variables (e.g., position.has_position, result.success), those variables MUST be the exact same variables assigned by the preceding REST close operations. A guard that checks t2_position when the close operation assigned to position is a silent no-op — it will always fail. The guard's input variable and the operation's output variable must share the same name and lexical scope. CRITICAL

RULE-TRUE-NEGATIVE-TESTING A guard that blocks 100% of cases — both legitimate successes and legitimate failures — is not 'working correctly.' It is a disconnected circuit. After deploying any guard, verify at least ONE true-positive (legitimate operation passes) and ONE true-negative (simulated failure is blocked) before declaring the fix complete. 100% block rate on a routine operation is a red flag, not a success metric. HIGH

RULE-FIX-PATH-AUDIT When a fix introduces new variables across multiple code paths (e.g., T2, G6, gate-fail), each path must be independently audited for assignment-guard alignment. Correctness in one path does not imply correctness in others — even when the pattern is identical. The audit must verify that the assignment statement and the guard statement reference the same variable name in every path. HIGH

Evaluation

Residual Risk: Production verification pending: the next T2 FULL_CLOSE and G6 CLOSE must be observed to confirm trade_closed is generated normally (not gate_close_aborted). Until verified, the fix is code-complete but not production-proven. Additionally, the pattern-migration blind spot is a cognitive vulnerability — future multi-path fixes remain susceptible unless explicitly audited per RULE-FIX-PATH-AUDIT.
