Explanation
Issue
#1981is open and directly linked. The current implementation adds opt-in recovery, preserves terminal failure status, validates trajectory and deviation records, salvages matched prefix frames, writesexploration_report.json, and filters selection with valid steps. The implementation still does not meet several concrete coding requirements. It reports completed, failed, missing, and corrupt tasks, but it does not distinguish intentionally stopped tasks from transient infrastructure failures. The policy provides failed-task and failed-task-ratio limits plus a minimum valid-frame limit, but it does not establish separate policies and ordering for unfinished tasks, usable or excluded frames, uncertainty classes, and failed FP labels, including interaction with FPratio_failed. The report does not establish retry history or accepted labels. The available tests cover missing output, terminal failure and restart state, split-file mapping, prefix salvage, and allow-list selection, but they do not establish grouped and one-task-per-job consistency, resume retry-budget behavior, the ratio-policy interaction withratio_failed, or all-invalid/all-failed stopping with strict training and model export.Resolution
Implement the remaining issue
#1981state classifications and separated ratio policies with explicit denominators and ordering. Record retry history and accepted-label outcomes in the report. Add regression coverage for grouped and one-task-per-job dispatch, resume behavior, unfinished and terminal-failure policy interaction, FPratio_failed, all-invalid/all-failed batches, and strict training and model export.

Reviewed head 96a72bf against base 0b9acec. Three independently reproduced recovery-path defects are attached inline: tolerated missing outputs still abort selection, incomplete/failed tasks can be reported as completed, and default split trajectories bypass cross-frame atom-map validation.
Validation: executed the unchanged recovery helpers and standard selector extracted via AST from this exact head, using temporary synthetic dump/deviation fixtures and NumPy. The completed-prefix fixture explicitly requested nsteps=1000 and contained a lost-atoms error log, with matching frames only at steps 0/10; this was a focused source-level reproduction, not an actual LAMMPS/DPDispatcher execution. No full-package test pass is claimed because dpdata is not installed locally. Existing exact-head Python 3.10/3.12, aggregate, Codecov, pre-commit and docs checks are successful; the CodeRabbit status is rate-limited, not a completed review. Companion dpdispatcher PR #687 remains open.

Scoped re-review of repair head e41c7f3 against the previously reviewed 96a72bf (PR base remains 0b9acec).
The three original concrete defects are addressed in the checked paths: both selectors skip empty recovery allow-lists before opening missing output; dispatcher failure state is persisted and report validation reads unfiltered deviations; atom count/type mapping is carried between split dump files. Re-running post_model_devi with persisted failed state preserved both failed status and excluded timestep 10. The submitted serialized task-state shape and enum values match companion dpdispatcher #687 at ee8e64e9b55a29fc68400b5da49ca24cf1f0b787.
One new duration-check regression is attached inline.
Validation caveat: executing the unchanged exact-head helper/selector function bodies and the submitted test methods through an AST harness produced 7 passes and 1 failure. test_task_report_preserves_terminal_failure_and_restart_state fails at tests/generator/test_model_devi_recovery.py:163: its second direct _recovery_task_report call omits task_state and expected_last_step, so it returns completed; the helper does not reload those inputs from exploration_report.json. Exercise the production post_model_devi/persisted-state path for the restart assertion, or supply the retained inputs explicitly. This test failure does not mean the production persisted-state replay is broken; that separate focused replay passed.
No installed-dpdata integration run or real LAMMPS/DPDispatcher job was performed. Exact-head Python workflow 38018926388 is still queued; pre-commit and docs statuses are successful.
