        ## Steps
        {steps_lines}

        ## Constraints
        - no architecture changes
        - reuse current assistant runtime and session state
        - 1C/MCP first
        - no fabricated values
        - missing route or capability is domain enablement work, not silent rejection

        - iteration_dir: `{iteration_dir}`
        - current_pack_dir: `{pack_dir}`
        {comparison_block}

        Required artifacts to inspect:
        - `{pack_dir / 'pack_summary.md'}`
        - `{pack_dir / 'pack_state.json'}`
        - `{pack_dir / 'scenario_acceptance_matrix.md'}`
        - `{repair_targets_path}`
        - all `scenario_summary.md`, `scenario_state.json`, and problematic `steps/*/step_state.json` files inside `{pack_dir / 'scenarios'}`

        Goal:
        - evaluate current domain-pack correctness for business meaning, route/capability quality, evidence quality, and absence of silent heuristic masking;
        - evaluate business usefulness, direct-answer-first behavior, state continuity, and field truthfulness, not only technical groundedness;
        - evaluate object-centric dialog continuity: stable `focus_object`, stable `answer_object`, reusable bundles such as `provenance_bundle`, and correct action resolution for pronoun-style follow-ups;
        - evaluate action-first follow-up behavior, answer layering, compactness of narrow micro-actions, and temporal honesty when the runtime broadens beyond the requested date window;
        - determine whether the gate `quality_score >= {target_score}` is reached;
        - if not, provide the smallest high-value fix targets for the coder.

        Rules:
        - `accepted` is allowed only if quality_score >= {target_score}, unresolved_p0_count = 0, and regression_detected = false;
        - `accepted` is forbidden if the evidence bundle shows `pack_state.final_status != accepted` or the deterministic repair targets still contain any `P0` or `P1` items;
        - `accepted` also requires `direct_answer_ok = true`, `business_usefulness_ok = true`, `temporal_honesty_ok = true`, and `field_truth_ok = true`;
        - when several failing steps share one deterministic repair focus, call out the highest-leverage shared focus first instead of only the lexicographically first failing step;
        - `partial` means the pack is usable but exactness, routing, or coverage is still insufficient;
        - `needs_exact_capability` means the primary blocker is a missing exact route or capability, but the loop should still continue autonomously unless a user decision is required;
        - `continue` means there is a clear next patch cycle;
        - `blocked` means the loop is stopped by a real hard blocker such as runtime/infrastructure failure, unavailable 1C data, or another condition that the repo cannot autonomously repair;
        - set `requires_user_decision = true` when the next step cannot be chosen safely without user input, for example:
          - an architecture fork or risky contour expansion;
          - a scope tradeoff or important business ambiguity;
          - a required observation anchor is missing and cannot be recovered safely from artifacts, 1C, or the current scenario state;
          - the only remaining implementation path would rely on a hack, brittle workaround, heuristic masking, or disproportionate complexity/risk;
        - if `requires_user_decision = true`, fill `user_decision_type` and `user_decision_prompt`;
        - if the pack is below {target_score} but there is still safe autonomous implementation work, keep `requires_user_decision = false`;
        - do not request user input merely because the score is still below {target_score}; request it only when the loop would otherwise guess, overfit, or risk architecture drift.
        - return machine-readable fields for: `user_intent_summary`, `expected_direct_answer`, `actual_direct_answer`, `direct_answer_ok`, `business_usefulness_ok`, `business_utility_score`, `direct_answer_priority_score`, `state_continuity_score`, `answer_shape_score`, `evidence_clarity_score`, `focus_object_continuity_ok`, `bundle_reuse_ok`, `followup_action_resolution_ok`, `temporal_honesty_ok`, `field_truth_ok`, `answer_layering_ok`, `recommended_state_objects`, `root_cause_layers`, `broken_edge_ids`, `violated_invariants`;
        - if the product found the evidence but failed to retain the selected object, provenance bundle, or another reusable resolved object across turns, classify that as `object_memory_gap` or `edge_carryover_gap`, not as a generic route problem;
        - if the product retained the item but resolved the wrong action over that item, for example `покажи документы по этой позиции` -> `documents_by_counterparty`, classify that as `followup_action_resolution_gap`;
        - if the product already resolved supplier/date/document details for the active item but failed to reuse that bundle for adjacent follow-ups, classify that as `bundle_reuse_gap`;
        - if a narrow business follow-up opens with numbered scaffolding such as `Блок 1/2/3` or a full generic trace packet instead of a compact direct answer, lower business usefulness explicitly rather than treating it as harmless formatting;
        - if the surfaced business field looks mislabeled, for example supplier vs organization, classify that as `field_mapping_gap`;
        - if the answer blurs exact-window evidence with nearest available out-of-window evidence, classify that as `temporal_honesty_gap`;
        - if the answer is technically grounded but still weak for a manager/accountant/operator, classify that as `business_utility_gap`.

        - do not present heuristic answers as confirmed;
        - do not touch unrelated files;
        - preserve already successful baseline flows.
        - preserve UTF-8 without BOM and the existing line structure of edited files; do not leave whole-file normalization-only rewrites or single-line collapses in the worktree;
        - use minimal local edits; if a tool rewrites a file into normalization noise, restore the original file first and then apply only the intended semantic patch;
        - use `root_cause_layers`, `broken_edge_ids`, `violated_invariants`, and business-utility scores from the analyst verdict to choose the smallest fix;
        - use the deterministic repair targets to choose the highest-leverage repair focus first; within that focus, patch the narrowest shared layer that can clear the most `P0`/`P1` targets without architecture drift;
        - the assigned deterministic repair focus below is mandatory for this iteration; do not switch to a lower-priority focus unless you are blocked from making a safe patch for the assigned focus;
        - if the analyst verdict is optimistic but deterministic repair targets still contain `P0` or `P1`, trust the deterministic repair targets and keep fixing the pack;
        - prioritize state continuity, selected-object persistence, stable `focus_object`, stable `answer_object`, reusable `provenance_bundle` / `sale_trace_bundle`, action-first answer behavior, compact micro-action answers, answer layering, temporal honesty, and field-truth mapping when those are the blocking layers;
        - do not broaden scope when the analyst says the defect is mainly `object_memory_gap`, `followup_action_resolution_gap`, `bundle_reuse_gap`, `field_mapping_gap`, `temporal_honesty_gap`, `answer_shape_mismatch`, or `business_utility_gap`;
        - when the verdict points to pronoun follow-ups or item-centric drilldowns, prefer a narrow object-state or follow-up-action fix over prompt inflation.

        Required outputs:
        - create `{iteration_dir / 'coder_plan.md'}` with a short plan;
