The planner Work Node workflow completed. It investigated src/scheduler.py:78 (_BUSY_TIMEOUT_MS = 30000), confirmed there's no rationale comment directly above the constant (the explanation only lives in the module docstring ~50 lines above), and — staying within the Planner role (no direct business-code edits) — produced a BRD packaging this as a single one-line Development Unit for a Code Agent: add a # comment directly above the constant referencing the existing docstring rationale about concurrent sqlite writers retrying instead of raising "database is locked". The BRD includes explicit acceptance criteria (single-line diff only, constant value unchanged, rest of file byte-identical, no test needed for a trivial comment).
It also updated its own agent memory (.claude/agent-memory/planner/project_scheduler_busy_timeout_comment_missing.md plus the MEMORY.md index) to record the gap and the "don't self-edit source, package as a Unit for Code Agent" pattern.
Current repo state: only planner memory files changed (one new untracked memory file, MEMORY.md modified) — nothing staged or committed, and no .graphlemon/runs/ artifact was created since this was a lightweight verify-and-plan check rather than a full BRD→PRD→SDD→Benchmark pipeline run.
