# Changelog

| Version | Date | Changes |
|---------|------|---------|
| 2.8 | 2026-04-21 | **Collaboration Depth Observer (v3.3.0)**: New `collaboration_depth_agent` (Agent Team grows from 3 to 4). Reads dialogue logs at every FULL/SLIM checkpoint and at pipeline completion; scores user-AI collaboration on 4 dimensions (Delegation Intensity / Cognitive Vigilance / Cognitive Reallocation / Zone Classification) per `shared/collaboration_depth_rubric.md` (rubric v1.0, canonical, CC-BY-NC 4.0). **Advisory only — never blocks.** MANDATORY checkpoints (2.5 / 4.5) do NOT invoke the observer (integrity gates preserved). Cross-model divergence flagged (not silently averaged) when `ARS_CROSS_MODEL` set. Rubric credits Wang, S., & Zhang, H. (2026). *IJETHE* 23:11. DOI 10.1186/s41239-026-00585-x. New lint: `scripts/check_collaboration_depth_rubric.py`. State tracker gains `dialogue_log_ref` per stage + `collaboration_depth_history[]` append-only. Reinforcement row added for checkpoint transitions. |
| 2.7 | 2026-03-27 | **Style Profile in Material Passport**: Pipeline orchestrator now carries optional Style Profile (Schema 10 in `shared/handoff_schemas.md`) through all stages. Produced by academic-paper intake Step 10 when user provides past writing samples. Consumed by draft_writer (Stage 2) and report_compiler (Stage 1) as soft writing voice guide. Does not affect integrity verification or review stages. Coordinates with deep-research v2.4 and academic-paper v2.5 |
| 2.6 | 2026-03-08 | **Handoff Data Schema**: Enhanced `shared/handoff_schemas.md` with 9 comprehensive schemas (RQ Brief, Bibliography, Synthesis, Paper Draft, Integrity Report, Review Report, Revision Roadmap, Response to Reviewers, Material Passport) with full field definitions, type constraints, and validation rules; orchestrator validates output against schemas before each transition. **Adaptive Checkpoint System**: Replaced static checkpoint template with 3-tier system (FULL/SLIM/MANDATORY) based on stage criticality and user engagement; FULL checkpoints include decision dashboard with metrics; SLIM auto-continues for experienced users; MANDATORY cannot be bypassed at integrity/review/finalization boundaries; awareness guard after 4+ auto-continues. **Mode Advisor**: New `references/mode_advisor.md` with unified cross-skill decision tree, common misconceptions table, user archetype recommendations, decision flowchart, and anti-patterns guide. **Team Collaboration Protocol**: New `references/team_collaboration_protocol.md` with 5 role definitions, per-transition handoff procedures, git branching/tagging strategy, conflict resolution matrix, and communication templates; state tracker extended with `assigned_to`, `approval_gate`, `team_notes` per stage and `schema_validation_log`. **Phase E Claim Verification**: New `references/claim_verification_protocol.md` with E1 claim extraction, E2 source tracing, E3 cross-referencing; verdict taxonomy (VERIFIED / MINOR_DISTORTION / MAJOR_DISTORTION / UNVERIFIABLE / UNVERIFIABLE_ACCESS); severity mapping (MAJOR_DISTORTION -> SERIOUS, UNVERIFIABLE -> SERIOUS, MINOR_DISTORTION -> MINOR, UNVERIFIABLE_ACCESS -> MEDIUM); integrated into integrity_verification_agent Mode 1 (30% spot-check) and Mode 2 (100%); pass/fail criteria updated to include Phase E verdicts. **Mid-Entry Material Passport Check**: Pipeline orchestrator now validates Material Passport on mid-entry; decision tree checks verification_status, freshness (< 24 hours), and content modification (version_label comparison); offers skip/spot-check/full re-verify options for Stage 2.5 when passport is valid; passport freshness validation rules added to `shared/handoff_schemas.md` |
| 2.5 | 2026-03-08 | External Review Protocol: structured intake of real journal reviewer feedback (text/PDF/DOCX); 4-step workflow (parse -> strategic coaching -> revise + Response to Reviewers -> completeness check); differentiated behavior from internal simulated review (no default "accept all", risk assessment per comment, user confirmation of parsed items); explicit capability boundaries (AI verification ≠ reviewer satisfaction) |
| 2.4 | 2026-03-08 | Stage 6 PROCESS SUMMARY: post-pipeline paper creation process record; asks user preferred language (zh/en/both); generates structured MD summarizing full human-AI collaboration history with user quotes, key decisions, iteration details, and lessons learned; mandatory final chapter: **Collaboration Quality Evaluation** (6 dimensions scored 1-100, bar chart visualization, What Worked Well / Missed Opportunities / Recommendations / Human vs AI Value-Add / Claude's Self-Reflection); compiles to PDF via LaTeX + tectonic; outputs `paper_creation_process_zh.pdf` + `paper_creation_process_en.pdf` |
| 2.3 | 2026-03-08 | Stage 5 FINALIZE: mandatory formatting style prompt (APA 7.0 / Chicago / IEEE); PDF must compile from LaTeX via tectonic (no HTML-to-PDF); APA 7.0 uses `apa7` document class (`man` mode) with XeCJK for bilingual support; font stack: Times New Roman + Source Han Serif TC VF + Courier New |
| 2.2 | 2026-03-05 | Checkpoint confirmation semantics (6 user commands with precise actions); mode switching rules (safe/dangerous/prohibited matrix); skill failure fallback matrix (per-stage degradation strategies); state ownership protocol (single source of truth with write access control); material version control (versioned artifacts with audit trail); cross-skill reference to `shared/handoff_schemas.md` |
| 2.1 | 2026-03 | Added plagiarism detection protocol (Phase D); enhanced integrity_verification_agent with originality verification (D1 WebSearch, D2 self-plagiarism); updated both verification modes |
| 2.0 | 2026-02 | Added Stage 2.5/4.5 integrity checks, two-stage review, mandatory checkpoints, Devil's Advocate, reproducibility guarantees, integrity_verification_agent |
| 1.0 | 2026-02 | Initial version: 5+1 stage pipeline |
