v7.2.1 — Milestone 6 Archive & Unified Task Template

What's New in v7.2.1

Release covering the 7.1.0 → 7.2.1 cycle: workflow friction fixes, V7 documentation consistency, the unified task template, and the Milestone 6 archive.

Unified Task Template (7.2.0)

• Unified canonical task-file template in task-generator with a polymorphic ## Source Context section supporting three provenances: orchestrator, telegram, manager.
• Source: metadata field in the task header for provenance tracking.
• Mandatory ## Goal and ## Local TODOs for all task files; # Task [NN]: [Title] title convention.
• telegram-issue-sync now references the unified template instead of defining an inline copy.
• archive-tasks milestone summaries now include a ## Source Distribution table.

Workflow Friction Fixes (7.1.0)

• Combined Discovery+Plan workflow — new <opencode_combined_task> template reduces Manager round-trips from 6 to 3, with explicit halt-on-architecture-mismatch conditions.
• Task numbering collision protection — Orchestrator-side pre-assignment validation plus a Collision Check in task-generator.
• Multi-phase task rule — single task file with inline ## Phase N: sections instead of separate subtask files.
• CHANGELOG Parse-Then-Append Protocol — prevents duplicate version/section headers.
• Memory hygiene — Memory Validation step in archive-tasks and Supersession Detection heuristic in project-memory.
• Pre-Commit Verification Gate (CRITICAL RULE 5) for DevOps/infrastructure tasks.
• Topic Shift Detection in <user_input_processing> for proactive context-switch notices.

Documentation Consistency (7.1.1)

• README now reflects V7: tree label, ## Key V7 Changes section, complete 28-skill skill-templates/ tree with standalone group labels.
• <execution_workflow> renumbered 1–9 (Phase 0 identity preserved), tags on own lines.

Milestone 6 Archive (7.2.1)

• Tasks 66–68 compacted into docs/history/milestone-6-summary.md and moved to tasks/archive/.
• System prompt version bumped to 7.2.1.
