Executing unit: u1

[Claude #3] Stage 3 Round #1 — u1 (backend axis 1)

unit_executed: u1

files_changed:

• src/phase_z2_pipeline.py

diff_summary:

• Inserted a new deterministic loop above application_plan_units.append({...}) (line 3972~3988) that builds v4_all_judgments_list for the current unit. Each entry now carries min_height_px alongside the existing catalog_registered field. Lookup is bound once per candidate (_contract = get_contract(c.template_id)), so catalog_registered and min_height_px share the same contract read (no extra cost vs prior single call).
• min_height_px source = (_contract or {}).get("visual_hints", {}).get("min_height_px") → matches the zone-scope pattern at src/phase_z2_pipeline.py:3771 and the catalog field at templates/phase_z2/catalog/frame_contracts.yaml:40,89,218,280,351,417,481,544,601,668. Returns None when the contract is unregistered or when visual_hints is absent → frontend tolerates undefined.
• Replaced the original inline list comprehension at the dict literal ("v4_all_judgments": [...]) with "v4_all_judgments": v4_all_judgments_list, so the dict literal stays clean and the lookup happens exactly once per candidate. Comment block above the field updated to mention IMP-11 D-2 (u1) addition (per-candidate min_height_px added (None when unregistered)).
• Additive only — no field rename, no removal, no semantic change to existing keys (template_id / frame_id / frame_number / v4_rank / confidence / label / catalog_registered unchanged in shape and value). Other Step 9 fields untouched. Zone-scope zone_region_plans[].min_height_px (line 3771) untouched. v4_candidates[] (non-reject path, line 4008~4018) untouched — minHeightPx will be undefined on legacy path per Stage 1 scope_lock guardrail.
• No AI call added. No catalog mutation. No new import. get_contract already imported (line 53).

scope_check:

• Stage 1 axis_1_backend_field: ✅ min_height_px added to each v4_all_judgments entry.
• Stage 1 guardrail "reuse same lookup (no extra cost)": ✅ single _contract binding per candidate, used twice in dict literal.
• Stage 1 guardrail "graceful when contract missing": ✅ (_contract or {}) short-circuit returns None, never raises.
• Stage 1 guardrail "no catalog write": ✅ get_contract is read-only.
• Stage 1 out_of_scope "Step 8 zone_region_plans output": ✅ untouched (still at line 3771).
• Stage 2 estimate_lines: 10 → actual diff = +17 / −12 (net +5) ≈ aligned; minor overhead from loop expansion vs comprehension for readability and single-lookup.

remaining_units: u2, u3, u4, u5

follow_up_issue_candidates: none discovered. All scope confined to Stage 1 axis_1_backend_field.

rewind_target: continue_same (u1 complete; u2~u5 remain per Stage 2 plan)

=== EVIDENCE ===

• Edited file: src/phase_z2_pipeline.py:3972-3988 (new v4_all_judgments_list builder) and :4025-4026 (dict literal now references the prebuilt list).
• Source of min_height_px: templates/phase_z2/catalog/frame_contracts.yaml:40 (visual_hints.min_height_px: 230) and 9 other contracts at lines 89/218/280/351/417/481/544/601/668.
• get_contract signature: src/phase_z2_mapper.py:56-57 → returns dict | None.
• Zone-scope precedent confirming .get("visual_hints", {}).get("min_height_px") shape: src/phase_z2_pipeline.py:3771.
• No new imports required; get_contract already in scope at src/phase_z2_pipeline.py:53.
• No commits or pushes performed per Stage 3 directive ("DO NOT commit or push").

STOP — awaiting Codex review for u1.
