Execute tasks from the active epic (specs/epics/eNN-slug/epic.yaml story tasks[]) one at a time, showing evidence after each step before proceeding.

HARD GATE — Do NOT proceed if on main or master. Run kickoff-branch first.

HARD GATE — Active epic must exist with runnable verify on each task. If missing, run plan-release then plan-work or build-epic.

Read specs/state.yaml (active_epic, active_story) and the matching specs/epics/*/epic.yaml. Parse depends-on in task descriptions for execution waves.

CONTEXT ISOLATION — Spawn each skill with a fresh context window. Pass decisions only through specs/state.yaml handoff — never rely on prior chat history.

Confirm with the user: step count, skip/reorder, stop-after step.

For each task in the active story:

a. Announce — task desc and verify command.

b. Execute — code or delegate-task / dispatch-agents for waves.

c. Run verify — must be green before advancing.

d. Log — non-obvious decisions in specs/state.yaml under decisions[] or handoff block.

e. Checkpoint — ask to proceed unless autonomous mode requested.

f. Story UAT — after last task, run manual verification script from story notes or verify-work.

On verify failure: fix and re-run; never advance on red.

Update specs/execution-status.yaml when a story/epic completes (bash scripts/sync-status-from-epics.sh or direct edit).

Report blocker; ask skip/adapt/stop; update epic capsule if plan changes.

Suggest: verify-work → run-evals → audit-code → simulate-agents → commit-message → release-branch

• Loop until behavioral correctness is verified: if a verify command passes but the observed behavior is still wrong, return to step 1 and run the execution cycle again.
