Gate Check

An option set is normally judged by whoever drafted it. That is the one judgment the drafter cannot make well: the options inherit the frame they were drafted from, so an option set standing on the wrong axis looks complete from inside. This skill puts an independent adjudicator on the option set itself — not on the work the gate is about — and then checks the adjudicator's reasoning against the substrate before either reaches you.

The check separates two things that usually collapse into one: who wrote the options and who says they are worth asking. Everything below exists to keep those apart, including from itself.

Caller Signature

/gate-check [gate?] [advisor?]

gate    : (implicit) | explicit draft   -- optional; defaults to the gate drafted in the current turn
advisor : { codex }                     -- optional; the independent adjudicator behind the

                                        --      conclusion asserted, and either a verdict — with

                                        --      the repairs available and what each changes }
                                        --      interface

The advisor is a parameter, not the identity. Any adjudicator satisfying that interface can drive the check, provided it is a genuinely separate reasoner — a second pass by the drafting agent does not satisfy it, because the independence is the whole mechanism.

Pipeline Overview

/gate-check [gate?] [advisor?]
  Phase 0 : screen + freeze     -- eligible gate? → freeze the option set verbatim, capture a substrate anchor
  Phase 1 : launch ∥ precommit  -- dispatch to the advisor (background), then record the expected
                                   controlling sources and verification criteria BEFORE any advisor
                                   output is visible
  Phase 2 : verify              -- collect the advisor's own words; check each cited ground against
                                   the substrate; check whether its stated falsifier could have
                                   defeated the reading and whether it is there
  Phase 3 : dispose             -- genuine | collapse | malformed | indeterminate | failed
  Phase 4 : synthesize          -- on a settled repair: rebuild the option set under the synthesis guards,
                                   then one external recheck, bounded
  present                       -- three vantage points always; ground-by-ground detail folds to one line
  observer                      -- armed for the session; every cycle converges or fails explicitly
