## 2026-04-09

- Continued implementation of `dragon_v2_rc1_restructuring_proposal_cn.md` after user asked to continue.
- Validated new structured reason metadata integration in `dragon_strategy.py`:
- post-run enrichment now appends `reason_layer/reason_family/reason_code` to events
- and `buy_reason_*` / `sell_reason_*` metadata to trades while preserving legacy `reason` strings.
- Ran compile check successfully:
- `py -3 -m py_compile dragon_strategy.py dragon_rc1_golden_baseline.py dragon_rule_catalog.py tests/test_rc1_golden_regression.py tests/test_reason_catalog_mapping.py`
- Regenerated golden baseline:
- `py -3 dragon_rc1_golden_baseline.py`
- refreshed manifest `dragon_rc1_golden_manifest.json` with new `generated_at` (`2026-04-09T00:57:54`) and core hashes:
- events core sha256 `8965d1b539a998d7d0aff04432aa2a47cf30ee40df013b9d8b7eb66a3d50a331`
- trades core sha256 `1298be56b0898266b0b854d62a979c00c20b01629393c82bb8c804faf852cb97`
- summary remains stable at RC1 baseline:
- trade_count `91`, event_count `272`, win_rate `52.75%`, avg_return `3.42%`.
- Regenerated layer attribution:
- `py -3 dragon_rule_layer_attribution.py`
- `dragon_rule_layer_attribution.md` still reports `no unknown reason mapping`.
- Ran tests successfully:
- `py -3 -m unittest discover -s tests -v`
- result: `3` tests passed (`OK`), covering golden regression and reason catalog mapping.
- Ran end-to-end daily signal pipeline regression:
- `py -3 dragon_daily_signal_pipeline.py --as-of 2026-04-08`
- pipeline executed successfully after strategy output enrichment, confirming no immediate downstream break from the added reason metadata columns.
- Hardened test portability:
- `tests/test_reason_catalog_mapping.py` no longer depends on local `dragon_historical_trade_details.csv`.
- It now uses `_load_indicator_snapshot(...)` + `DragonRuleEngine.run(...)` to derive release-window reasons directly from strategy output.
- Re-ran tests after this change: all `3` tests still pass.
- Added a next-stage optimization proposal for execution:
- file: `dragon_v2_rc1_optimization_proposal_cn.md`
- focus: phase-3+ plan with `core/secondary/bridge` execution split, reason-string decoupling, weak-family optimization in new branch, and stronger regression/reporting acceptance gates.
- User requested to proceed in OpenSpec format.
- Added `openspec/` structure for `dragon/v2`:
- `openspec/config.yaml`
- change package `openspec/changes/rc1-layered-governed-optimization/` with:
- `.openspec.yaml`
- `proposal.md`
- `design.md`
- `tasks.md`
- `specs/layered-rule-engine/spec.md`
- `specs/structured-decision-state/spec.md`
- `specs/weak-family-research-governance/spec.md`
- `specs/golden-regression-governance/spec.md`
- Updated `USER.md` to persist preference: future optimization/governance推进 should use OpenSpec workflow.
- User requested full uninterrupted execution ("全部执行完，再找我，中途不停"), and this round followed that mode.
- Completed OpenSpec task execution for `rc1-layered-governed-optimization`:
- added layered modules `dragon_rule_engine_v2.py`, `dragon_rules_core.py`, `dragon_rules_secondary.py`, `dragon_rules_bridge.py`.
- `dragon_strategy.py` kept as compatibility facade and migrated high-risk control paths to structured fields:
- `entry_reason_layer/family/code`, `last_real_sell_reason_layer/family/code`
- bridge flags for predictive and pending deep-oversold chains.
- Added compatibility and path-regression tests:
- `tests/test_no_silent_path_change.py`
- `tests/test_bridge_chain_regression.py`
- `tests/test_deep_oversold_pending_paths.py`
- Full test suite now: `8` tests passed.
- Added layered attribution/report artifacts:
- `dragon_layered_pnl_attribution.py`
- `dragon_layered_pnl_attribution.csv`
- `dragon_layered_family_pnl_attribution.csv`
- `dragon_layered_entry_pnl_attribution.csv`
- `dragon_layered_exit_pnl_attribution.csv`
- `dragon_layered_pnl_attribution.md`
- Added migration audit note:
- `dragon_migration_audit.md`
- Executed weak-family experiment pack:
- created branch `alpha_next_weak_family_cleanup`
- added `dragon_weak_family_experiments.py`
- generated:
- `dragon_weak_family_experiment_summary.csv`
- `dragon_weak_family_trade_diff.csv`
- `dragon_weak_family_execution_stress.csv`
- `dragon_weak_family_experiment_config_snapshot.json`
- `dragon_weak_family_experiment.md`
- Added acceptance report:
- `openspec/changes/rc1-layered-governed-optimization/acceptance-summary.md`
- Updated OpenSpec task status to fully checked in:
- `openspec/changes/rc1-layered-governed-optimization/tasks.md`
- Continued OpenSpec推进 with a new change pack:
- `openspec/changes/predictive-deepoversold-physical-isolation/`
- Added proposal/design/tasks/specs plus acceptance summary for this change.
- Implemented physical isolation modules:
- `dragon_bridge_predictive_break.py`
- `dragon_deep_oversold_classifier.py`
- `dragon_deep_oversold_confirmation.py`
- Replaced predictive/deep-oversold inline predicates in `dragon_strategy.py` with module calls (compatibility path preserved).
- Added module-level tests:
- `tests/test_predictive_bridge_module.py`
- `tests/test_deep_oversold_modules.py`
- Validation completed:
- golden baseline unchanged (`91` trades, core hashes unchanged),
- layer attribution remains `no unknown reason mapping`,
- full test suite now `14` tests passed,
- daily signal pipeline smoke (`--as-of 2026-04-08`) passed.
- Continued OpenSpec execution with a third change pack:
- `openspec/changes/execution-decoupling-rollout-governance/`
- Added proposal/design/tasks/spec docs and acceptance summary for this change.
- Implemented execution-level decoupling:
- new module `dragon_execution_runtime.py`
- `dragon_strategy.py` now delegates `run(...)` compatibility loop to the runtime module.
- Implemented rollout-governance hardening:
- new module `dragon_rollout_governance.py`
- new checker `dragon_rollout_governance_check.py`
- forward pipeline now auto-runs checker:
- `dragon_forward_observation_pipeline.py` calls rollout checker before HTML refresh.
- rollout checker now publishes explicit operational decision artifacts each run.
- New governance artifacts now generated:
- `dragon_rollout_state.json`
- `dragon_rollout_governance_snapshot.csv`
- `dragon_rollout_governance_report.md`
- `dragon_rollout_rollback_runbook.md`
- Added rollout governance tests:
- `tests/test_rollout_governance.py`
- Validation reruns after this wave:
- `py -3 -m unittest discover -s tests -v` -> `17` tests passed.
- `py -3 dragon_rc1_golden_baseline.py` -> core hashes unchanged.
- `py -3 dragon_daily_signal_pipeline.py` -> passed.
- `py -3 dragon_forward_observation_pipeline.py` -> passed.
- latest rollout decision snapshot after validation:
- decision `FORWARD_OK`
- active branch `alpha_first_glued_refined_hot_cap`
- fallback branch `alpha_first_selective_veto`
- Improved one-click tracking entry:
- upgraded `update_dragon_reports.ps1` to print latest bar date, rollout decision, active/fallback branch, and gate counts after each run.
- added optional switches:
- `-StrictGate` (non-`FORWARD_OK` exits with code `2`)
- `-OpenReport` (opens `dragon_reports_index.html` after run).
- Updated `dragon/data_fetcher_v2.py` for T-day freshness + cache writeback behavior:
- `fetch_index_data_v2(...)` now forces refresh when `end_date` covers today (`T日`) instead of reusing stale in-memory cache.
- `fetch_index_data_with_latest_snapshot_v2(...)` now writes merged latest-snapshot data back only if the matching cache key already exists.
- If cache key does not exist, writeback is skipped by design (`有则回写，无则跳过`).
- Added regression tests:
- `tests/test_data_fetcher_tday_cache.py`
- covers: non-T-day cache hit, T-day forced refresh, conditional cache writeback.
- Validation after change:
- `py -3 -m unittest discover -s tests -v` passed (`20` tests).
- `py -3 dragon_daily_signal_pipeline.py` smoke run passed.
