status: codified
version: 1.0.0
tier: episodic
description: Scan project memory for v1.7.1 lifecycle frontmatter · report tier distribution + promotion candidates (reinforce_count >= promote_after) · NO LLM.
inputs:
- project (str, optional): project slug · defaults to active project
- mem_dir (path, optional): override · skip project resolution
outputs:
- tier_distribution (counts by working/episodic/semantic/procedural/unset)
- decay_status (now_active/expired/never)
- promotion_candidates (list of {path, current_tier, next_tier, reinforce_count, promote_after})
- total_memories

# lifecycle_report
Aggregate the 4-tier lifecycle schema landed in v1.7.1 across a project's
memory directory. Identifies memories ripe for tier promotion using the
LLM-free deterministic rule: `reinforce_count >= promote_after`.
## When to use
- Pre-promotion audit: which working-tier memories should be promoted to
episodic? Which episodic to semantic?
- Decay sweep: which memories have hit their `forget_at` ISO8601 timestamp?
- Tier health check: ratio of working/episodic/semantic/procedural memories.
## Why codified
- Frontmatter parsing is stable (won't change · v1.7.1 fixed schema)
- Deterministic output · no LLM
- Used by the 4-tier paradigm validation per paper3 cite (llm-wiki2 fuse)
