 - S10 real intraday feedback validation is implemented, deployed, and remote-verified: added `docs/AI_ICT_TraderCockpit真实反馈验证_S10_2026-05-21_v1.md`; used real remote evidence (`operator_feedback_count=3`, recent Candidate `4610` observation with `operator_agreement=unclear`, `paper_ticket_count=0`, `paper_execution_count=0`, `weekly_review_entry_count=0`) to tighten the six-card copy without adding features. `Observe Only` now says the explicit gap (`FVG retrace is not confirmed yet; no trade`), `Wait` says the operator should wait for `trigger-chart FVG retrace confirmation`, `Risk` warns against treating the watch as a signal, and `Historical Edge` is reduced to Study / Review-only language without first-screen PF/DD/expectancy detail. Validation passed focused operator/static/docs tests, `node --check`, script static checks, full unit discovery (`807` tests), `git diff --check` with only LF/CRLF warnings, deploy smoke over 11 endpoints, remote ops smoke, readonly live analysis smoke, six-card field smoke, and gstack browser verification with no console errors. Evidence screenshot: `output/playwright/s10-trader-cockpit-real-feedback-six-card-1366x768.png`.
 - S11 real intraday use loop is implemented, deployed, and remote-verified: remote `/trader-mode` showed the S10 six-card conclusion clearly (`FVG retrace is not confirmed yet; no trade`), so the operator recorded a real `No Trade` instead of tuning more copy. This created observation `9237` with `operator_agreement=no_trade` for Candidate `4610`; `operator_feedback_count` increased from `3` to `4`, while `paper_ticket_count=0`, `paper_execution_count=0`, and `weekly_review_entry_count=0` stayed unchanged. A feedback mapping bug was fixed so Trader Cockpit buttons now write `no_trade` and `need_more_evidence` explicitly instead of collapsing both into `unclear`. Validation passed focused tests, `node --check`, deploy smoke over 11 endpoints, remote ops smoke, readonly live analysis smoke, field verification, and gstack browser verification with no console errors. Evidence screenshot: `output/playwright/s11-trader-mode-no-trade-feedback-1366x768.png`.
 - S12 real intraday use loop was attempted and the anti-duplication guard was confirmed: remote `/trader-mode` still showed a clear Chinese `Observe Only / no trade` readout, the UI wrote `POST /trading/shadow-paper/observe -> 201`, and screenshot evidence was saved at `output/playwright/s12-trader-mode-fifth-feedback-1366x768.png`. The R2 count did not increase from `4/5` to `5/5` because `shadow_paper_observations` upserts by `(instrument_id, observation_date, timeframe, session_code)`, so another same-day same-session LONDON `No Trade` updates observation `9237` instead of creating a duplicate sample. Current live state: `observed_shadow_day_count=14`, `shadow_observation_count=17`, `shadow_observation_day_count=13`, `operator_feedback_count=4/5`, `operator_observation_feedback_count=4`, `operator_feedback_day_count=3`, `paper_ticket_count=0`, `paper_execution_count=0`, `weekly_review_entry_count=0`, and `runtime_clear_for_shadow` is currently blocked by `broker_sync_degraded:BTC-USDT:okx_read_credentials_missing`.
-- Current assisted-analysis next gate: proceed to S13 only after a distinct real feedback sample exists: wait for a new real session/date feedback sample, or a legitimate non-duplicate feedback channel already present in the product, to move `operator_feedback_count` from `4/5` to `5/5`. Do not repeat-click the same LONDON/day sample, do not tune copy unless the next real feedback is `unclear` or `disagree`, and do not fabricate paper ticket / paper execution / weekly review samples from blocked candidates. Also clear the read-only runtime blocker (`okx_read_credentials_missing`) before claiming R2 evidence progress. Do not add new product features, do not restart external-context/archive/digest long-tail work, do not physically delete S1 deprecated surfaces yet, and keep `execution_allowed`, `decision_support_ready`, `real_live_ready`, risk governor, trust bucket, and operator confirmation protocol unchanged.
+- S13 read-only runtime blocker recovery and fifth real feedback sample are complete: remote `.env` had empty `OKX_API_KEY` / `OKX_API_SECRET` / `OKX_API_PASSPHRASE`, so the existing local read-only OKX values were restored into the remote runtime env only; `LIVE_TRADING_ENABLED` and all execution/readiness gates stayed unchanged, and temporary credential fragments/backups were removed. Remote runtime now has `current_blockers=[]`, `readonly_account_context_status=available`, `live_analysis_assistant_ready=true`, `decision_support_ready=false`, `execution_assist_ready=false`, `real_live_ready=false`, and `must_not_trade=true`. Then the existing shadow-observation feedback path recorded a distinct `ALL` / `no_candidate_monitor` observation `7949` as `operator_agreement=agree`, moving `operator_feedback_count` from `4/5` to `5/5` without creating paper tickets, paper executions, or weekly review entries. Current R2 state: `next_validation_gate=paper_ticket_sample_gate`, `operator_feedback_count=5/5`, `operator_observation_feedback_count=5`, `operator_feedback_day_count=3`, `paper_ticket_count=0`, `paper_execution_count=0`, and `weekly_review_entry_count=0`. Validation passed documentation consistency tests, `git diff --check`, remote ops smoke, readonly live analysis smoke, direct shadow-paper field smoke, and gstack console check.
+- Current assisted-analysis next gate: stop collecting duplicate operator feedback; wait for a real executable candidate before creating shadow paper ticket / paper execution samples, then let real execution-derived Journal / weekly review evidence appear. Do not fabricate paper samples from blocked candidates or no-candidate observations. Do not add new product features, do not restart external-context/archive/digest long-tail work, do not physically delete S1 deprecated surfaces yet, and keep `execution_allowed`, `decision_support_ready`, `real_live_ready`, risk governor, trust bucket, and operator confirmation protocol unchanged.

Continue with S13: first clear the read-only runtime blocker if still present, then collect one distinct real operator feedback sample from a new session/date or legitimate non-duplicate feedback channel. Repeated same-day same-session `/trader-mode` clicks are intentionally de-duplicated and must not be used to satisfy R2. If the next real feedback is clear (`agree` / `no_trade`), do not tune copy; if it is `unclear` or `disagree`, adjust only existing text/hiding rules around `Reason`, `Wait`, and `Risk`. Do not restart external-context/archive/digest long-tail work, do not create order-submission features, do not physically delete S1 deprecated surfaces yet, and do not fabricate R2 paper samples.

 S12 结论：不能再用同一 LONDON/day 的重复按钮点击来推进 `operator_feedback_count`。下一条可计数反馈必须来自新的真实 session/date，或来自已有产品内合法且非重复的真实反馈通道；paper ticket / paper execution / weekly review 仍必须等待真实 executable candidate 和执行派生样本，不能从 blocked candidate 伪造。

+## 8. S13 只读 blocker 恢复与第 5 条反馈记录
+
+2026-05-21 S13 先处理 S12 留下的 `runtime_clear_for_shadow` 阻塞。复核发现远端运行 `.env` 中 `OKX_API_KEY` / `OKX_API_SECRET` / `OKX_API_PASSPHRASE` 为空，而本地 `.env.local` 已有对应键位。处理方式：
+
+- 只补齐远端运行环境中的 OKX 只读凭据键位。
+- 不改 `LIVE_TRADING_ENABLED`。
+- 不改 `execution_allowed`、`decision_support_ready`、`real_live_ready`、risk governor、trust bucket、operator confirmation protocol。
+- 不新增下单、撤单、实盘执行能力。
+- 远端临时凭据片段和 `.env` 备份副本已删除，避免多留敏感配置副本。
+
+恢复后远端状态：
+
+- `runtime_status.current_blockers=[]`
+- `readonly_account_context_status=available`
+- `live_analysis_assistant_ready=true`
+- `decision_support_ready=false`
+- `execution_assist_ready=false`
+- `real_live_ready=false`
+- `must_not_trade=true`
+
+随后使用现有 shadow observation 反馈入口，为当天 `session_code=ALL` 的 `no_candidate_monitor` 观察记录真实 `agree` 反馈。这不是 S12 的 LONDON 重复样本，而是不同去重键的真实 no-candidate 观察：
+
+- observation `7949`
+- `session_code=ALL`
+- `observation_status=operator_feedback_recorded`
+- `system_recommendation=no_candidate_monitor`
+- `operator_agreement=agree`
+- `candidate_id=null`
+- `paper_ticket_id=null`
+- `paper_execution_id=null`
