-## Cross-Genome Lint
+## Cross-Genome Pull (Navigation Skill)
 
-_Manual, monthly — requires operator initiation. Not automated._
+Cross-genome knowledge moves by **pull, never push**: the genome you are working in draws material *in*; nothing is ever written into another genome. The cross-genome reading is performed by a deterministic collector **outside any agent's context**, so the agent still operates within ONE genome (Immutable Rule 1 holds). The `cross_source` registry flag decides which genomes may be read as sources.
 
-1. Use `qmd search "<concept>"` to find pages covering the same concept across genomes.
-2. Identify:
-   - Concepts defined in 2+ genomes with potentially conflicting definitions.
-   - Entities referenced across genomes without a canonical cross-genome wikilink.
-   - Concepts in genome-X that should link to genome-Y but don't.
-3. Report findings. Do not modify any files.
-4. For each finding: create a conflict note in the genome where resolution belongs, following that genome's §Conflict procedure.
+### How it works
+
+Three actors, mirroring the ingest two-phase split:
+
+1. **Collector** (`collect-crossgen.sh`, deterministic, agent-free). Clones each genome flagged `cross_source: yes` **read-only at its remote HEAD** — a disposable checkout, for freshness; never the pinned submodule state. Reads each `wiki/index.md` plus the relevant pages and assembles a **dossier of excerpts with provenance** (source genome, page, date/commit). Writes nothing to any source genome.
+2. **Synthesis** (agent, navigation skill, `read`/`edit` only). Reads **only the dossier** — a single artifact inside the working genome's context — then the skill deposits **one** abstract, non-private raw into the working genome at `raw/articles/crossgen-&lt;topic&gt;-&lt;&lt;YYYY-MM-DD&gt;.md`, and STOPS.
+3. **Target ingest.** The working genome's own standard pipeline processes that raw → PR → human gate. Same gate as any other source.
+
+### When to pull
+
+Pull is initiated deliberately (operator- or context-driven, never on a timer). Produce a crossgen raw ONLY when all three hold:
+
+1. **Ownership elsewhere.** The concept, entity, or pattern is defined and maintained in another genome, and you need it framed for the working domain.
+2. **Structural relevance.** It influences decisions, patterns, or entities here — not a casual mention.
+3. **No fresh local coverage.** `qmd search "&lt;concept&gt;"` in the working genome returns nothing, or only a stub that needs enrichment.
+
+If in doubt, do NOT pull. A missed cross-reference is cheaper than crossgen spam.
+
+### Boundaries (enforced by the master)
+
+- **Sources are restricted to `cross_source: yes` genomes.** A genome flagged `no` (e.g., a client / confidential file) is NEVER read as a source — the collector skips it physically. The wall decides what may flow; it does not rely on the agent's discipline.
+- **Sources are read-only, at HEAD.** No write, commit, branch, or PR in any genome other than the one being worked on.
+- **NEVER `git submodule update --remote`.** Read other genomes via disposable read-only clones — never by moving this master's submodule pointers (that is ASK FIRST).
+- **NEVER read `*/private/*`.** The skill runs `PRIVATE_CONTEXT: disabled` and `private/` is an encrypted blob; even on an unlocked host, private paths are off-limits.
+- Confidential / client genomes are normally isolated from cross-genome pulls entirely (operator policy). Whatever genome a pull runs into, the output raw must be abstract and non-private.
+
+### Output raw (the only artifact written)
+
+**Path (in the working genome):** `raw/articles/crossgen-&lt;topic&gt;-&lt;&lt;YYYY-MM-DD&gt;.md`
+Plain text. No YAML frontmatter (raw is immutable input). **No wikilinks of any kind** — never a `[[../genome-*/...]]` path.
+
+```markdown
+&gt; Cross-genome pull | Into: genome-&lt;working&gt; | Sources: genome-&lt;a&gt; (wiki/concepts/x.md), genome-&lt;b&gt; (wiki/entities/y.md) | HEAD: &lt;short-sha…&gt; | Date: YYYY-MM-DD
+```
+
+# &lt;Topic&gt; (synthesized from other genomes)
+
+## What the source genomes say
+[Abstract, faithful synthesis of the relevant material. Plain text, no private data, no wikilinks.]
+
+## Relevance to this genome
+[Why it matters in the working domain; textual references to existing local entities, if any.]
+
+## Suggested local action
+[Semantic hint for this genome's ingest: e.g., create/update wiki/concepts/&lt;concept&gt;.md, map local relationships.]
+
+---
+
+- Each pull writes a **new, dated** crossgen file — never overwrite or edit an existing raw (raw is immutable). Deduplication happens later, at the **wiki** level: the working genome's normal ingest reconciles against existing pages via its §Conflict procedure.
+
+- The raw is processed by the working genome's standard ingest as an ordinary `raw/articles/` source — no special path.
+
+- The collector and the raw deposit are the **deterministic** side of the skill; the agent only synthesizes content. Agents never create, modify, or delete files in any `raw/` directly.
+
+---
+
+That closes the remaining audit items for `agents-master.md`. The file is now fully pull-oriented and consistent with the dossier.
