Two root causes behind 'every task parks, and slowly':
1. SINGLE-SHOT INVOKER: subscription Claude calls ran as 40-turn, tool-enabled
agentic sessions (--max-turns 40, $2 budget) for what are pure reasoning->JSON
completions — minutes-long, and Claude wandered/returned unparseable output.
_DEFAULT_MAX_TURNS 40->1 + allowed_tools=[] -> fast deterministic single turn.
2. PLANNER FEEDBACK KEY MISMATCH: the review stage writes verdict/findings, but
_format_review_feedback read decision/notes/comment (never present) -> the
planner re-planned with EMPTY feedback, re-introduced the rejected flaw
('assumptions persist'), hit the review cap, parked. Now reads verdict/findings
(old keys kept as fallback) so GPT-4.1's objections reach the re-plan.
Plus: park notifications infer the phase the task was IN (review/plan/clarify)
instead of the terminal 'parked'.
Tests: planner real-verdict-keys regression + coordinator phase-inference. 1149 pass.
- retriever: add save_memory() writing to _box-drafts/ review queue, add
memory_dir param to retrieve() for isolated test routing
- handbook: new load_handbook_conventions() with safe no-op contract (returns
"" when dir absent/empty/unreadable, never raises)
- clarifier_llm: add context_provider=None seam to ClaudeClarifier and
build_claude_clarifier_callables(); failure in provider is silent
- planner: add context_provider=None seam to build_plan_prompt() and plan_node()
- coordinator: thread context_provider through default_plan_node_factory(),
only pass kwarg when non-None to preserve stub-monkeypatching in tests
- tests: 19 new WS5 tests covering all seams (1063 total, all passing)
