memory-log-render

Convert a consumer's .log.jsonl into a readable log.md Markdown file. The rendered view uses greppable line prefixes and groups events by date.

When to Use

• On demand: user asks "show me the log" or "render the activity log"
• After bulk operations: post-ingest or post-lint when the log has grown
• As part of memory-lint --fix: regenerate the rendered view if stale

Parameters

--consumer (optional)

Consumer ID. Resolved via ADR-021 D4 precedence: explicit > wrapper > auto-detect.

--tail (optional, default: all)

Only render the last N entries. Useful for large logs.

--since (optional)

Only render entries after this ISO 8601 date.

--output (optional)

Override output path. Defaults to sibling of .log.jsonl → log.md (e.g., .aiwg/research/.log.jsonl → .aiwg/research/log.md).

Operation

1. Resolve consumer — determine which log to render.
2. Load topology — read memory.topology.log path from consumer's manifest.json.
3. Read JSONL — parse each line as JSON. Skip malformed lines (warn in output).
4. Group by date — cluster entries by ts date portion.
5. Render Markdown — for each entry, produce:

## [2026-04-14] ingest | anthropic-2024-constitutional.pdf
Touched 3 pages: anthropic.md, constitutional-ai.md, summaries/2024-constitutional-ai.md.
Duration: 14.2s. No contradictions.

6. Write output — overwrite the log.md file (this is a generated view, not an append).
7. Log event — append a log-render entry to .log.jsonl via memory-log-append.

Line Prefix Convention

Every operation line starts with ## [YYYY-MM-DD] <op> | <subject> — this makes the rendered log greppable:

grep "^## \[" .aiwg/research/log.md | tail -5
grep "ingest" .aiwg/research/log.md
