Drew T 0189445b9a chore(phase-30 S49): FINAL session checkpoint — 177 banked, 95.2% instr, R22 213/213
- checkpoint block refreshed for a fresh session (R30/checkpoint-before-pause): the TU-spread
  test is the named FIRST action, the regen chain and gate contract are spelled out, and the
  >=16 head's three open items are listed with their evidence.
- promote gate_lane.py into tools/ (it was scratchpad-only): accepts slate OR confirmed shapes,
  explicit draft paths, R32 coverage assertion (refuses to report 0 as a result), dirty-tree
  abort, no outer timeout, per-function propagation after.
- session: 179 commits, 177 instances banked, 5 R22 clean-fleet gates all 213/213.

"""The wave gate driver — the S49 practice, paid for in two incidents (cookbook §169 law 3).
Usage: tools/gate_lane.py <wavedir> <slate-or-confirmed.json> [results.json]
Accepts either shape (`name` or `fn` per record) and takes an explicit `draft` path when present.
The contract, and why each clause exists:
- group drafts by (binary, destination split .c)
- gate_stage --no-propagate --commit, NO outer timeout (the tool owns its own)
- revert any residue between groups; abort loudly if the tree is dirty at entry
- propagate PER FUNCTION afterwards, committing each
Usage: gate_lane.py <wavedir> <slate.json> [results.json]"""
