Homebrew core's sem-cli now ships 0.27.0; the skill was written against
0.25.0. Built v0.27.0 from source and re-ran the skill's claims on a
synthetic repo holding a two-file Dart program and its TypeScript twin.

What changed underneath the skill:

• 0.27 folded the verbs: callers/refs/context/entities became
  find --callers|--refs|--context|--in, log/blame became
  history [--blame], setup/update/telemetry moved under sem config,
  login/review/xref under sem cloud. Old spellings still work, so the
  allowlist keeps both and adds history.
• 0.26 fixed Dart call resolution (upstream #491). The skill's headline
  Dart warning ("0 edges, a green 'No other entities are affected'")
  no longer reproduces: constructor and typed-receiver calls resolve
  exactly as in the TS twin, and what stays unresolved (an untyped
  receiver) is unresolved in TS too. Re-verified synthetically only;
  the section says to confirm on DittoXCactus before relying on it.
• Caller answers now carry an INCOMPLETE verdict and a possible-callers
  list instead of a green check. That list is where cross-language name
  matches still surface, labelled as unresolved.
• New sem certify <range>: local, read-only review certificate, with
  --arch --view and a self-contained --html page (no external
  resources; checked in the v0.27.0 source and rendered). Allowlisted.
• New sem check runs the project's checkers and tests. Deliberately
  NOT allowlisted: it executes repo code.

preferred-tooling.md's compact table moves to the new spellings and
points at sem certify for "where's the risk".
