Ephemera paths: resolve FEATURE_CODE / <CODE> then follow templates/skills-ephemera-paths.md (feature root .skills/<CODE>/). Resolve pack seeds in this order, first path that exists: (1) templates/ beside this SKILL.md, (2) ${CLAUDE_PLUGIN_ROOT}/templates when that variable is set, (3) ../../../templates relative to this SKILL.md.

Build By Story

Drive an approved story-unit plan to completion: derive review units from requirement stories, run the shared continuous scheduler inside each unit, stop for a human after each unit, resume from the unit ledger, and finish with whole-branch review.

Continuous multi-task orchestration without unit barriers is build-in-waves. Controller-implements-without-subagents is build-inline. Invoking this skill selects story-unit execution. If the header already says continuous, hand off to build-in-waves. If the user wants no subagents, name build-inline.

Context rule: workers and reviewers resume only within a valid semantic lane lease. Hard rotation triggers start a fresh context from the feature capsule and task delta; bulk artifacts travel as paths under .skills/, never pasted session history.
