`wikilink::to_ids` rewrites name-addressed links to the canonical id (id-first resolve: an already-id target is left alone, a name → its id with any label preserved). `Store::migrate_wikilinks_to_ids` runs it over every body and re-saves through update_node (which collapses + materializes by id); idempotent. Surfaced as the `migrate.wikilinks` RPC + RemoteStore forward + the `heph migrate-links` CLI command (not auto-run — the owner runs it once per store). Name-resolution + the canonical-context hack stay for now so legacy links keep resolving pre-migration; retiring them is a later tidy. Tests: to_ids unit + a heph-core migrate integration (rewrite + materialize + idempotency). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

//! Wiki-link display projection (tech-spec §8.4): a body's links are stored as
|
|
//! canonical bare `[[NODEID]]`. `update_node` collapses a name-matching
|
|
//! `[[NODEID|Name]]` label back to bare (the daemon expands it again on read);
|
|
//! a custom label is preserved. `get_node` here returns the **raw stored** body
|
|
//! (expansion is a daemon-read concern), so it shows the collapsed form.
