 ## Instructions
 
+### Gate records are deterministic inputs ([org-internal #5656] N-04)
+
+When the work item carries gate records (`gate` tool results — metadata
+`exit_code`, `duration_ms`, `ci_run_id`), those records ARE the command
+outcomes for mechanical questions (tests/typecheck/lint): cite the exit code
+verbatim (`gate <id> (<tier>): exit_code=<n> -> green|red` — canonical block
+in `packages/octopus/src/gate/consume.ts`) and never substitute a model's
+narration of command output. A claim that disagrees with a record's
+exit_code is a finding (record wins); a mechanical claim with no record is
+unverifiable — request the citation. A green verdict-cache hit
+(`metadata.verdict_cache.key`) counts the same as a fresh run.

 4. For each checklist item, determine whether the {ARTIFACT_NOUN} satisfies it.
    Every checklist item must receive a PASS or FAIL verdict.

    (reviewer_count > 1), use the slot-prefixed form {DIM}R{k}-F{NNN} with your
    1-based slot k (e.g. TOPOR1-F001) so parallel slot files never collide on id.

+6b. Code graph availability (worktree sessions): if `codegraph_status` is
+   unavailable or reports no index for the tree under review (typical when
+   reviewing from a session worktree whose per-worktree `.codegraph/` index
+   has not finished building — see `<instance-root>/rules/code-graph.md`), do NOT
+   silently substitute grep+read for structural questions ("who calls /
+   what depends on / where defined"). Instead:
+   - For symbols on the MAIN branch side (baselines, design refs, cross-session
+     frozen contracts), you MAY query the main checkout's index (path given in
+     your dispatch preamble) and cite `main:<path>:<line>`.
+   - If no index is reachable at all, mark the affected checklist items NA
+     with reason "codegraph unavailable — structural check degraded to grep"
+     and emit one INFO finding (id `{DIM}-F001`-style, in your dimension's own
+     code) recording the degradation, so the Synthesizer can surface it.
+   Findings derived purely from grep+read when a graph query was required are
+   treated as low-confidence and may be waived in synthesis.
