It also runs BINDINGS.RS: its no-?ws test loads the app, which spawns web/worker.js, which imports the glue, which calls bindings.rs start() and OpfsFs::open(), and the test then asserts a grid draws. This invariant was named opfs_is_run_but_bindings_is_not and asserted the opposite in FIVE places for months (here, the crate/3 fact above, two context/repo-map.md lines and improvise-bck) -- every copy written before the harness landed and none re-read after. A never-run claim in prose is unfalsifiable by anything in this repo: the CI job checks this KB for CONSISTENCY, not truth, and the error UNDERSTATED coverage so nothing failed and nobody looked. What is genuinely unrun, BY ENGINE: Safari/WebKit (no OPFS in Playwrights build) and any non-Chromium engine for the shell spec. That is deliberately scoped to engines rather than written as a closed list of everything unreached, because a closed list is how the previous version of this invariant went wrong in the other direction: two wasm_bindgen exports on WorkerServer, documents() and refresh(), have NO caller in web/*.js or harness/ and so are run by nothing (the .refresh( hits in harness/opfs-contract are OpfsFs::refresh, a different method). The lesson the rename is about applies to its own replacement: a coverage claim in prose is unfalsifiable by anything in this repo, so state what IS covered and scope what is not, rather than enumerating an absence.').

doctrine(suite_speed,'Two numbers, because the ambiguity between them is what let this drift: NO SINGLE TEST BINARY may exceed 2 seconds, and the WORKSPACE WALL CLOCK is the sum of them.

Re-MEASURE rather than re-assert: cargo test --workspace prints a "finished in" per binary. Excludes compilation, and excludes harness/ (Playwright, minutes, its own CI job).').
