+<purpose>
+Autonomous repair operator for failed task verification. Invoked by execute-plan when a task fails its done-criteria. Proposes and attempts structured fixes before escalating to the user.
+</purpose>
+
+<inputs>
+- FAILED_TASK: Task number, name, and done-criteria from the plan
+- ERROR: What verification produced - actual result vs expected
+- PLAN_CONTEXT: Adjacent tasks and phase goal (for constraint awareness)
+- REPAIR_BUDGET: Max repair attempts remaining (default: 2)
+</inputs>
+
+<repair_directive>
+Analyze the failure and choose exactly one repair strategy:
+
+**RETRY** - The approach was right but execution failed. Try again with a concrete adjustment.
+- Use when: command error, missing dependency, wrong path, env issue, transient failure
+- Output: `RETRY: [specific adjustment to make before retrying]`
+
+**DECOMPOSE** - The task is too coarse. Break it into smaller verifiable sub-steps.
+- Use when: done-criteria covers multiple concerns, implementation gaps are structural
+- Output: `DECOMPOSE: [sub-task 1] | [sub-task 2] | ...` (max 3 sub-tasks)
+- Sub-tasks must each have a single verifiable outcome
+
+**PRUNE** - The task is infeasible given current constraints. Skip with justification.
+- Use when: prerequisite missing and not fixable here, out of scope, contradicts an earlier decision
+- Output: `PRUNE: [one-sentence justification]`
+
+**ESCALATE** - Repair budget exhausted, or this is an architectural decision (Rule 4).
+- Use when: RETRY failed more than once with different approaches, or fix requires structural change
+- Output: `ESCALATE: [what was tried] | [what decision is needed]`
+</repair_directive>
+
+<process>
+
+<step name="diagnose">
+Read the error and done-criteria carefully. Ask:
+1. Is this a transient/environmental issue? → RETRY
+2. Is the task verifiably too broad? → DECOMPOSE
+3. Is a prerequisite genuinely missing and unfixable in scope? → PRUNE
+4. Has RETRY already been attempted with this task? Check REPAIR_BUDGET. If 0 → ESCALATE
+</step>
+
+<step name="execute_retry">
+If RETRY:
+1. Apply the specific adjustment stated in the directive
+2. Re-run the task implementation
+3. Re-run verification
+4. If passes → continue normally, log `[Node Repair - RETRY] Task [X]: [adjustment made]`
+5. If fails again → decrement REPAIR_BUDGET, re-invoke node-repair with updated context
+</step>
+
+<step name="execute_decompose">
+If DECOMPOSE:
+1. Replace the failed task inline with the sub-tasks (do not modify PLAN.md on disk)
+2. Execute sub-tasks sequentially, each with its own verification
+3. If all sub-tasks pass → treat original task as succeeded, log `[Node Repair - DECOMPOSE] Task [X] → [N] sub-tasks`
+4. If a sub-task fails → re-invoke node-repair for that sub-task (REPAIR_BUDGET applies per sub-task)
+</step>
+
+<step name="execute_prune">
+If PRUNE:
+1. Mark task as skipped with justification
+2. Log to SUMMARY "Issues Encountered": `[Node Repair - PRUNE] Task [X]: [justification]`
+3. Continue to next task
+</step>
+
+<step name="execute_escalate">
+If ESCALATE:
+1. Surface to user via verification_failure_gate with full repair history
+2. Present: what was tried (each RETRY/DECOMPOSE attempt), what the blocker is, options available
+3. Wait for user direction before continuing
+</step>
+
+</process>

+All repair actions must appear in SUMMARY.md under "## Deviations from Plan":

+
+<constraints>
+- REPAIR_BUDGET defaults to 2 per task. Configurable via config.json `workflow.node_repair_budget`.
+- Never modify PLAN.md on disk - decomposed sub-tasks are in-memory only.
+- DECOMPOSE sub-tasks must be more specific than the original, not synonymous rewrites.
+- If config.json `workflow.node_repair` is `false`, skip directly to verification_failure_gate (user retains original behavior).
