Plan gate — cross-vendor adversarial review digest (intent-to-completion)
Artifacts: spec.md (rev 14) + plan.md + plan.index.json (48 tasks / 11 waves) — bytes embedded verbatim, sha256 c4a5ddec64a0c8f3a285944c1a15536efd58d7d6f1e410c92cc78113d427e3f6, 268761 chars
Workflow: adversarial-review (wf_8195246e-611), intensity standard; cross-vendor lanes: openai/gpt-5.6-sol; degraded: none
Provenance: dispatch-adversary → litellm/gpt-5.6-sol, 262 output tokens; dispatch-adversary → litellm/gpt-5.6-sol, 411 output tokens; dispatch-adversary → litellm/gpt-5.6-sol, 7561 output tokens
Verdict: revise; findings 1 (1 should-fix); disagreements 1; dropped 4

Summary: The plan's wave structure holds up under in-tree verification: a script over plan.index.json finds zero same-wave file collisions in any of the 11 waves, the finish-step flag contract task 3 wires against is established by task 23 in wave 1 (not task 26), the `pushed: no` / required_successor CLI projections rest on wave-0 schemas and projections rather than the later finish-step writers, and the absence of a live-release task is the spec's explicit design (§10.1 / A33: the bootstrap stage is a post-wave operator-gated stage, never a plan task, and the index meta.solution says so). All four of reviewer 1's blockers are therefore dropped as context errors from a reviewer that never saw the tree or the full spec (its own process note says the successful pass ran on condensed descriptions). One defect survives, confirmed live: task 7's verify for commands/masterplan.md is a single `grep -nE` alternation that exits 0 on any one token (reproduced: the pattern currently exits 1 against the sequencer and exits 0 on a one-token line), while every other multi-token check in the plan (tasks 1, 8) uses AND semantics. That is a should-fix, not a blocker, because task 7's op-table-parity and prompt-structure suites remain the primary gate; the verify line should still be tightened before execution.

Findings (severity-first):
 1. [should-fix] Task 7's verify command for commands/masterplan.md uses grep -E alternation (OR semantics), so it passes when any single required token is present rather than requiring all of them.
