# lib.sh — shared logic for the phased-execution skill.
# Sourced by run-task.sh, run-phase.sh, and auto-phase.sh. Not meant to be run directly.
#
# Phase state lives in files, not chat context:
# .agents/PLAN.md master plan, LOCKED DECISIONS (binding)
# .agents/phases/todo/NN_name/ pending phase: 00_phase.md (overview) + NN_task.md task files
# .agents/phases/todo/NN_name.md legacy single-file phase (still executable)
# .agents/phases/complete/ finished phases — mirrors the todo/ layout
# .agents/reports/ per-task executor reports, stderr, validation logs
# .agents/phase-sessions/ child pi session files (resumable fixers)
#
# The unit of execution is the TASK: each task file runs in its own pi
# subprocess (fresh context) with bounded fixer retries, and
# .agents/validate.sh runs after EVERY task. A unit only moves to complete/
# after the child exits 0, the child's stream ends with a clean final
# report, and validation passes. When all of a phase's tasks are done,
# 00_phase.md runs as the phase's final pass (any remaining inline work +
# completion criteria + phase-level verification); moving it completes the
# phase and is the commit point. Children never commit — by default
# (PHASE_COMMIT=1) the harness makes ONE atomic commit per completed phase
# (code changes + the file move + the executor reports), scoped so the
# owner's pre-existing worktree changes are left alone, and pushes it when
# the repo has a remote (PHASE_PUSH=1; see commit_phase / push_phase).
