> **${var}** — mode selector; space-separated tokens, order-independent, all optional:
> - **mode** (`sync` | `report`, default `sync`) — `sync` opens a PR with the framework changes; `report` computes the delta and notifies, mutating nothing (dry run).
> - **`repo=owner/name`** — override the upstream source repo (else auto-resolved from this instance's `parent`, falling back to `aeonfun/aeon`).
> - **`reset=<sha|fork-point>`** — force the stored baseline to `<sha>` (or the merge-base with upstream) before running. Recovery / backfill lever.

Today is ${today}. This is the fleet's **downstream updater** - the counterpart to `fork-fleet`. `fork-fleet` looks *outward* from the parent to find work in the forks worth pulling *up*; this skill runs *inside* an instance and pulls the parent's shipped framework changes *down* - new skills, script/harness fixes, workflow and doc updates - and lands them as a reviewable PR. It is how an instance stays current with `aeonfun/aeon` without a hand-run rsync-overlay rebase.

## Operating principles

- **PR, never push to `main`.** Every framework change ships as one reviewable PR. The operator merges.
- **Never clobber operator config.** `aeon.yml`, `STRATEGY.md`, `soul/`, `memory/`, `output/`, `.mcp.json` and the git-derived catalogs are instance-owned. Upstream changes to them are **surfaced for manual review in the PR body**, never written into the tree.
- **3-way, not blind overwrite.** A framework file the operator has already customized is **auto-merged** when its local edits and upstream's edits touch disjoint regions (a real `git merge-file` 3-way, S6); it is only listed as a **conflict** for a human when the same lines changed on both sides. This is what lets a hand-narrowed workflow keep receiving unrelated upstream fixes without a manual merge every run.
- **Silent when in sync.** Baseline == upstream HEAD ⇒ nothing to do, no notification.
