The auto-detection "not installed" heuristic accepted any resolution failure
whose message merely CONTAINED the package name, unterminated — so a missing
platform-binary sibling package (what a deploy replacing node_modules
mid-restart leaves behind) read as "the accelerator is not installed", and
brainy silently served the default WASM engines with zero journal lines. A
production restart storm paid 90 seconds of throttled WASM compile behind
exactly that hole. The name must now terminate where it ends (quote,
whitespace, punctuation, end) — a sibling package, an inner file path, or a
dependency failure is a broken install and init() throws, as the guard's own
law always stated.
Second door: activate() returning false (the documented graceful decline)
warned on console.warn, which `silent: true` patches away — an invisible
degrade. The decline now narrates via the always-on channel.
Also exports CanonicalCounts from the public surface (the coverage-ledger
denominator type consumers read through getCanonicalCounts()).
Pinned in tests/unit/plugin-activation-loudness.test.ts (five error shapes;
the decline warn under silent: true).
