Anthropic retired the alias model after 4.6: dateless IDs are now pinned snapshots, so every frozen pre-4.6 alias kept a permanent (latest) tag (Opus 4/4.1/4.5, Sonnet 4/4.5) while newer pinned models got none. Use the API display_name verbatim (stripping any stale suffix) instead of appending (latest) to every alias. This matches all other providers, where a rolling -latest pointer is owned upstream rather than hardcoded in names. Also sweeps the six stale canonical names. Supersedes anomalyco#6433.

Summary
Supersedes #6433 — root fix instead of data patch (close #6433 in favor of this).
buildAnthropicModelappended(latest)to every alias (canonical_idset). That was correct pre-4.6, but Anthropic froze old aliases and made 4.6+ dateless IDs pinned snapshots, so Opus 4/4.1/4.5 and Sonnet 4/4.5 kept a permanent(latest)tag while Opus 5 / Sonnet 5 got none. Same rot would repeat on every future release.Changes
packages/core/src/sync/providers/anthropic.ts: use the APIdisplay_nameverbatim, stripping any stale trailing(latest)— never invent the suffix. Matches all other providers, where a rolling-latestpointer is owned upstream.packages/core/test/sync.test.ts: replacedlabels Anthropic aliases as latestwithnever invents latest tags+strips stale latest suffix; updated inheritance mock name.Verification
