Apply review findings from mining PR #61/#63/#64 and the recent merged PRs:
- conf_draft_node: drop the agentic invoker config (max_turns=8 + Read/Grep/Glob
+ budget) that merged #61 reverted live (#60); use max_turns=4 tools-off like
the planner. The draft is a reasoning->JSON node — repo context is folded into
the prompt, never fetched via Claude tools (feedback_claude_sdk_single_shot).
Invert the test that pinned the old tools-on contract.
- confluence_writer: record the dedicated Phase.CONF_DRAFT/CONF_GATE/CONF_WRITE
values instead of borrowing VERIFY/REVIEW/BUILD, so the ledger/transitions/
dashboard show the real lane.
- invoker: note the allowed_tools seam is replicated from merged #61 (drop on a
future rebase; byte-equivalent default None->[]).
- dashboard: document that conf_* vertices need no _NODE_TO_STAGE remap (node id
== stage key, identity fallback resolves them).
Verified (no change needed): coordinator confluence gate shares the plan gate's
crash isolation (_emit never raises, ledger write fail-soft); confluence_* state
channels persist via declared PipelineState channels + checkpointer; Flow B edge
hooks VERIFY's approved terminus, orthogonal to #61's plan-gate-approve routing.
Full suite 1564 passed; ruff + format clean.
