v7.2.26 — json_builder Tool & Schema-Aware Validation

What's New

json_builder Tool (Core Feature)

New schema-aware JSON construction and validation tool that replaces manual cat schema + hand-written validation across the entire workflow system.

5 Commands:

• init — Create schema-compliant JSON skeleton from any of 24 registered schemas
• set — Incremental field setting with instant per-field validation (supports path syntax: field.sub, arr[+], arr[0], arr[?key=val])
• validate — Full structural (JSON Schema draft-07 subset) + semantic quality validation
• merge — Merge multiple same-schema JSONs with dedup_by_path strategy (keeps highest relevance)
• info — Compact schema summary replacing raw schema file reads (~100-500 lines → ~20 lines)

Validation Layers:

• Layer 1: Structural — required/type/enum/const/pattern/minLength/minItems/minimum/maximum
• Layer 2: Semantic — generic rationale detection, key_code/topic_relation quality checks, circular dependency detection
• Layer 3: Completeness — all required fields filled with non-empty values

24 Registered Schemas: explore, diagnosis, finding, plan, plan-fix, plan-legacy, fix-legacy, tech, guidelines, issue, queue, review-dim, review-deep, debug-log, discussion, task, solution, verify, discovery-state, conflict, registry, team-tasks, plan-verify
