goal-grind

name	goal-grind
description	Execute exactly one lead-selected Zig actuation operation and return event-bound evidence to the coordinator. Use after $goal-actuating has prepared a capability; do not create authority, choose scope, recurse, resolve review findings, or claim goal completion.

Goal Grind

Mission

Consume one already-prepared capability with the smallest owner-correct action.

prepared actuation-operation/v1
-> bounded effect
-> Zig kernel observation
-> action result
-> return to $goal-actuating

Ephemeral input

selected_operation:
  run_id:
  step_id:
  idempotency_key:
  owner_boundary:
  paths: []
  effect: inspect | edit | verify
  obligation_refs: []
  capability: AKC1-...
  review_resolution_ref: # review edits only

The raw capability exists only in the active executor. Never persist, quote, log, or return it. Its digest and the complete admitted operation already live in the append-only event chain.

Procedure

1. Confirm ledger state --source actuation --run RUN_ID is prepared and its pending step exactly matches the selected operation.

2. Re-read the bounded paths.

3. For edit, make only the owner-correct change on the admitted paths, then consume and observe it:

   ledger record --source actuation --run RUN_ID --capability "$CAPABILITY"
   ledger observe --source actuation --run RUN_ID --step STEP_ID
   

4. For inspect or verify, let the kernel execute the obligation-owned verifier:

   ledger execute --source actuation --run RUN_ID --capability "$CAPABILITY"
   

5. Return changed paths, commands, transition event digests, observations, and any failure signature. Stop after this one operation.

Prefer replacement-kernel when local repair would add semantic machinery, distribute one invariant, or preserve a dominated abstraction.

Output

operation_result:
  run_id:
  step_id:
  idempotency_key:
  owner_boundary:
  changed_paths: []
  commands: []
  kernel_event_refs: []
  observations: []
  result: passed | failed | blocked | regress
  failure_signature:
  public_effects: []

Guardrails

• Do not prepare or select another operation.
• Do not create or loosen the GoalContract.
• Do not implement raw review prose.
• Do not perform public effects.
• Do not claim node or goal completion; return evidence to the coordinator.
