Conciseness

The body is efficient with mostly purposeful prose (idempotency notes, stderr-routing rationale, provider logic), but a few explanatory sentences could be trimmed, landing between the lean 5-anchor and the mostly-efficient 3-anchor.

Actionability

Guidance is fully executable and copy-paste ready throughout — grep checks, a complete Dockerfile ARG/RUN/ENV block, the entrypoint diff, build and smoke-test commands, and docker exec/docker logs verification — matching the 'fully executable; copy-paste ready' anchor.

Workflow Clarity

Clear phased sequence (Pre-flight, Apply, Restart/Verify, Troubleshooting) with explicit validation checkpoints — 'rebuild and smoke-test', 'Confirm mnemon hooks are registered', 'Test memory recall' — plus troubleshooting feedback loops for error recovery, matching the 5-anchor.

Progressive Disclosure

Single-file guide with well-organized section headers and no nested/deep references; good structure and easy header-based navigation, but at ~170 lines it is longer than the under-50-line case the 5-anchor's 'appropriately split' bar presumes, so it sits at 'good structure; minor organization gaps'.

Specificity

Lists several concrete actions — 'Add persistent graph-based memory', 'recall past context before responding', 'remember insights after each turn' — which matches the 'several specific actions; minor gaps' anchor rather than the fully comprehensive 5-anchor example.

Completeness

The 'what' is clear (add persistent memory, recall before responding, remember after each turn) but the 'when' is entirely missing — there is no 'Use when...' clause, which per the guidelines caps completeness at 3.

Trigger Term Quality

Natural terms like 'memory', 'recall', and 'remember' are present, but common variations/synonyms (context, history, past sessions) are missing and there is no explicit 'Use when...' framing to surface triggers.

Distinctiveness Conflict Risk

The 'graph-based memory via mnemon' niche is mostly distinct with low overlap risk, but the lack of explicit trigger phrases keeps it just short of the 5-anchor's clear-niche-with-distinct-triggers bar.
