PCE Promotion - Distill, Promote, Rollback

Use this skill when the task is specifically about moving knowledge through the v2 promotion pipeline.

Pipeline

observe -> distill -> promote -> rollback

activate and feedback live in pce-core; this skill focuses on the promotion boundary itself.

State Gate

1. Check pce_memory_state
2. If Uninitialized, run pce_memory_policy_apply
3. Continue only after policy state is ready

1. Distill

Create a reviewable promotion candidate from one of these sources:

• source_observation_ids
• source_claim_ids
• active_context_id

Recommended Inputs

{
  "source_observation_ids": ["obs_..."],
  "proposed_kind": "fact",
  "proposed_scope": "project",
  "proposed_memory_type": "knowledge",
  "note": "why this should become durable"
}

Distill Rules

• Distill is the required abstraction boundary between raw capture and durable memory.
• Use working_state, knowledge, procedure, or norm for durable intent.
• Do not propose evidence for durable promotion; it is reserved for micro memory.
• Candidate output is reviewable and includes invariant checks.
• promotion_queue is local governance state; it is not a sync surface.

2. Promote

Promote a pending candidate into durable meso or macro memory.

Required Inputs

{
  "candidate_id": "pq_...",
  "provenance": {
    "at": "2026-03-24T00:00:00Z",
    "actor": "claude"
  }
}

Recommended Inputs

• reviewers: reviewer IDs or names, especially for principle/macro memory
• review_note: why promotion is justified

Promotion Rules

• Project scope lands in meso memory.
• Principle scope lands in macro memory and should carry review lineage.
• Boundary monotonicity is enforced at promotion time.
• Secret-bearing candidates cannot silently become durable canonical memory.
• Promotion returns a rollback_token; keep it in mind when the claim is controversial or newly validated.

3. Rollback

Use rollback when a durable claim is wrong, stale in a harmful way, or superseded.

Required Inputs

{
  "claim_id": "clm_...",
  "reason": "superseded by corrected design",
  "provenance": {
    "at": "2026-03-24T00:00:00Z",
    "actor": "claude"
  }
}

Rollback Rules

• Rollback is append-only and auditable.
• Do not delete or mutate history in place.
• Rolled-back claims drop out of canonical sync/export surfaces.
• Use rollback before re-promoting corrected knowledge when the prior durable claim should no longer be trusted.

Decision Guide

• Raw note, log, or branch-local state: observe
• Candidate abstraction with lineage: distill
• Canonical durable memory: promote
• Incorrect canonical durable memory: rollback

Common Failure Modes

• Trying to promote raw text directly: Observe first, then distill
• Using scope: session as durable memory: Session belongs in micro observation, not durable promotion
• Using secret in durable writes: Keep secrets in observe only
• Skipping provenance: promote and rollback require provenance.at
