# SM Flow Execution Hardening Acceptance

## Result

Implemented `sm-flow-execution-hardening` as protocol/document changes only.

Updated artifacts:

- `.agents/skills/sm-flow/SKILL.md`
- `.agents/skills/sm-flow/references/phase-contracts.md`
- `.agents/skills/sm-flow/references/fallbacks.md`
- `skill-workbench/docs/sm-flow/workflow.md`
- `openspec/changes/sm-flow-execution-hardening/tasks.md`

## Verification

- Static verification:
  - Confirmed explicit phase checkpoint and stage-completion rules exist in `SKILL.md`.
  - Confirmed Phase 2 question-pool behavior and Phase 1.5 / 2.9 cross-artifact checks exist in `phase-contracts.md`.
  - Confirmed fallback declaration and recording requirements exist in `fallbacks.md`.
  - Confirmed `workflow.md` explains the same execution-hardening model without introducing mandatory output templates.
- OpenSpec verification:
  - Implementation/documentation tasks `1.1` to `3.2` are complete.
  - Validation tasks `4.1` to `4.4` are complete.

## Acceptance Scope Check

- Satisfied by protocol/document changes alone: yes
- Requires standardized phase-report output format: no
- Requires fixed checkpoint/alignment templates: no

## Unverified

- OpenSpec CLI validation passed: `openspec validate sm-flow-execution-hardening`.
- No automated tests were needed because this change only modifies protocol and documentation artifacts.

## Archive Status

- OpenSpec change is not archived.
- User still needs to be asked whether to archive after validation is complete.
