S166 intake product head 2a65a2d7a5a59c5e9a4743e9770f11db9e88e0f5 remains a
separate review candidate. This pack may cite its contract id only; it does
not duplicate intake adapters.

demo command: bundled fixtures, label fixture_demo even when local gates pass.
run/import: caller-supplied JSON only; never load exchange/01 or /02 fixtures.
TownSquare kit remains synthetic (conversation.demo:true). This pack does not
claim arbitrary conversation extraction.

Local gate pass is local_run_ok — not actual_completion, external completion, or
customer adoption.

No escrow, token, payment backend, private worktree paths, or raw transcripts.
