6phase — Router

Triage

Classify before coding. Higher-complexity signal wins. User can override.

Signal	Track	Path
Bug fix, docs-only, config, ≤3 files	Fast	P3 → P6
Clear approach, 4-10 files, single concern	Standard	P1+P2 → P3 → P4 → P5 → P6
Arch decision, unclear reqs, multi-module, major refactor	Full	P1 → P2 → P3 → P4 → P5 → P6
Unknown feasibility, new tech	Spike	P0 → P1 → ...

Multi-task: Unrelated tasks → separate cycles. Related changes forming one feature → one cycle.

User artifacts: User provides design → start P2. Plan → start P3. Code → start P4. Emit: [6PHASE: SKIP → Px | reason: ...]
