eou-promote

Evaluate EOU Lifecycle

Evaluate $eou_id against the maturity model and produce a lifecycle recommendation.

This skill has function: promote — it evaluates and recommends. It does not execute lifecycle transitions. The human owner executes promotion via activate and retirement via retire after approving this recommendation.

Inputs

• $eou_id (required) — the EOU identifier to evaluate; must match a spec file and registry entry.
• target_stage (optional) — the lifecycle stage to transition to; if omitted, infer the logical next stage from the gate table.

Required reading

1. foundry/maturity-model.yml — promotion gate requirements per lifecycle stage
2. foundry/registry.yml — current registration status and lifecycle stage
3. foundry/governance.yml — approval authority for lifecycle transitions

Also read (to evaluate evidence)

4. foundry/audits/eou-audits/{eou_id}.audit.yml — most recent audit (required for draft → pilot and above)
5. foundry/self-evolution/regression/cases/*.yml — filter to YAML files where the eou_id field equals $eou_id — regression coverage
6. foundry/runs/ — scan for trace.yml files containing eou_id: {eou_id} — execution traces required for pilot → active

Promotion prerequisites (all must be satisfied)

Gate	Required evidence
candidate → draft	At least one complete spec pass and one failed-case regression fixture
draft → simulated	Spec complete, dry-run or sandbox trace available, no open critical findings
draft → pilot	Passed eou-audit, ECP approved for any open findings, human owner on record
pilot → active	Minimum 3 successful pilot traces, zero open critical findings, human owner approval
active → monitored	Elevated-risk event or audit finding requiring close observation; no gate, owner decision
monitored → stable	Minimum 5 clean traces post-monitoring period, zero open high/critical findings
stable → active	Reverse to active when monitoring obligation lapses; owner decision
Any → deprecated	Owner decision recorded; replacement EOU or alternative documented
Any → retired	Superseded by successor EOU or determined to have no operational value; archived, not deleted

Stop conditions

Halt and report before proceeding if:

• $eou_id does not resolve to a spec file in foundry/eous/ or foundry/meta-eous/.
• $eou_id is not present in foundry/registry.yml.
• foundry/maturity-model.yml does not exist — gate requirements cannot be evaluated without it.
• No target transition is specified and the current lifecycle stage has no obvious next step.

Procedure

1. Load the EOU spec at foundry/eous/{eou_id}.yml (or foundry/meta-eous/{eou_id}.yml).
2. Identify the current lifecycle_stage.
3. Check each gate requirement for the target transition.
4. For each missing gate, record the gap and block the recommendation.
5. Write the lifecycle recommendation.

Output

Write to foundry/governance/lifecycle/{eou_id}.recommendation.yml:

eou_id:
current_stage:
recommended_action:  # promote_to | deprecate | retire | hold
target_stage:        # if promote_to
gate_results:
  - gate:
    satisfied: true | false
    evidence:  # file path or description
    gap:       # what is missing (if not satisfied)
recommendation_rationale:
requires_human_approval: true  # always true for promote_to:active, retire

Constraints

• Output recommendation only — do not modify the EOU spec, registry, or governance files directly.
• Do not execute any lifecycle transition. Evaluation and execution are separate acts:
  • function: promote (this skill) — evaluate gates and recommend
  • function: activate — execute promotion to active (requires human approval)
  • function: retire — execute retirement (requires human approval)
• A missing audit, trace, or owner record blocks promotion — record the gap, do not invent evidence.
• promote_to: active always requires requires_human_approval: true.

Scope Note

Upstream: receives an EOU id. Typically invoked when an EOU at pilot or active stage is being considered for the next lifecycle transition.

Downstream: produces a lifecycle recommendation only. Execution (activate, retire) is a separate human-approved step, not part of this skill — promote evaluates, humans decide.

Related: $eou-audit (upstream gate — audit pass is required input for promotion to active); the activate and retire execution functions (not skills, but governed verbs that consume this skill's recommendation after human approval).

Pipeline: eou-audit (pass) → eou-promote → human approval → activate | retire
