wiki-foldlisted

# Extractive log fold Create an additive rollup of raw `wiki/log.md` entries in the knowledge base. Never modify, move, or delete child entries or their pages. Do not fold a fold, and do not trigger a fold automatically. The skill runs in a knowledge base session. ## Select a bounded range Use batch exponent `k` with size `2^k`; default to `k=4`. An explicit entry range may override it. If fewer entries exist than requested, report the shortfall and stop rather than folding a partial batch. Read the selected log entries completely. Read referenced child pages only when the log lacks enough context: target 0-10 reads, hard ceiling 15. A missing page stays an explicit `page_missing` record. Derive the structural id only from inputs: ```text fold-k{K}-from-{EARLIEST-DATE}-to-{LATEST-DATE}-n{COUNT} ``` If `wiki/folds/{FOLD_ID}.md` already exists, return a no-op. Replacing it needs an explicit request and a `replace` write the user reviews. ## Draft extractively Follow [fold-template.md](references/fold-template.md). Every child log entry has one deterministic `child_key` in frontmatter and exactly one matching row in the Child Entries table. Do not deduplicate children by page; the final Child Pages list may be deduplicated. Every outcome names its source entry. Every number is verifiable in the selected entry. A cross-entry theme names at least two contributing entries. Prefer "ambiguous in source" or "source missing" to invention. When a child page and a log entry dis
