Research direction
Start by confirming that #891, #893 and #897 have merged, then read the split seams recorded in docs/roadmap/risks-and-decisions.md near line 80. The work touches forgelm/cli/_parser.py, the _DEFERRED_SPLITS entry in tools/check_module_size.py, and check_cli_help_consistency.py, which pins every --help string. Done means the sub-package keeps every public name importable, the module-size check passes without the deferral, and the CHANGELOG names F-PR29-A1-06/07/08.

Description
Deferred work ·
F-PR29-A1-06 / A1-07 / A1-08: _parser.py· severity Low · cost ~4-8 h · recorded indocs/roadmap/risks-and-decisions.md:80
Summary
forgelm/cli/_parser.py is a deferred module split: every subcommand's argparse surface lives in one file, and check_cli_help_consistency.py pins every --help string, so the diff is wide and must be taken once. The module-size guard holds it to a fatal no-growth budget, but nothing pays the debt down until someone takes the split.
Condition or budget
Phase 16 S5, S7 and S11 have all landed (each edits this file); they are #891, #893 and #897
State today (re-checked 2026-10-09)
1370 code lines against a budget of 1372 (deferred at 1320).
Related
#667 and #668 track how the module-size guard counts lines and accepts budget raises; decide them before relying on a module's budget.
Acceptance criteria
- The module becomes a sub-package along the recorded seams, behaviour-neutral, with every public name still importable from its current path.
- Its
_DEFERRED_SPLITSentry is removed fromtools/check_module_size.pyand every resulting module is under the normal ceiling. - Test patch targets that named the old module are retargeted to the module that resolves the name at call time (the
forgelm/verify.pysplit found five that silently moved). - The row is removed from the deferral table and the CHANGELOG names its ID (the table's removal contract).
Recorded in docs/roadmap/risks-and-decisions.md (read at f94595f) and re-checked against the code on 2026-10-09. The row leaves that table only when the fix is on main, the CHANGELOG names its ID and any promised guard exists.
