 ### Changed
 
+- A board hosts `wasi:clocks/wall-clock`, which every guest built with Rust 1.100 imports for its standard library's
+  locks. A board keeps no calendar, so the time it gives is how long its clock has run. The interface moves from
+  `edge_toolkit::board::COVERAGE_IMPORTS` to `HOSTED_IMPORTS`.
+- **Breaking:** `et-ws-wasi-runner` built with `nn` no longer links ONNX Runtime: it opens the library when a guest
+  first uses `wasi:nn`. Set `ORT_DYLIB_PATH` to the library to use, as the runner's image now does, or keep one
+  beside the runner. Without either it asks the system for one by name, and on Windows that is the older copy in
+  System32, which the runner refuses by version.
 - **Breaking:** `et_ws_wasi_runner::run_module` takes the serial ports it lends a component as a fifth argument, a
   `BTreeMap` from each port's name to its device. Pass an empty map to lend none, as a build without the `lidar`
   feature does whatever it is given.

+# Every signature the probe set has been seen to give, one entry per distinct signature.
+# An entry is one GPU, driver, backend, interface and browser combination, or a CPU and math library where no GPU
+# is involved. A numeric signature is filed under its interface and the mode it was taken in: webgpu-split,
+# webgl2-split or webgl1-split when a browser compiled each expression in a shader of its own, and the -combined
+# forms when it compiled them all in one shader, because the two can differ on one device. WebGPU is filed the same
+# way whoever implemented it, a row with no browser being wgpu called directly. host and wasi-nn are not WebGPU: the
+# CPU answering as f32 arithmetic and its math library, and the probes as ONNX operators behind wasi:nn. canvas is a
+# classic 2-D canvas fingerprint kept for comparison: a page's own scene, read with getImageData from a canvas the
+# page made. canvas-browserleaks is the BrowserLeaks canvas test, read with toDataURL from a canvas made in a
+# sandboxed frame; its md5 result is the signature that site shows. A new mechanism brings its own interface name.
+# A signature can be shared by several devices, so each entry lists every place it has been seen, one row each, under
+# "seen"; when a new sighting matches an existing entry, add a row rather than a duplicate entry. The label is only a
+# summary of the rows. A row names, from fixed sets of values:
+#   browser    chrome, firefox, safari, opera (and whatever else the webbrowser crate names), brave, chromium, deno,
+#              edge, librewolf, samsung-internet, tor-browser, or none where no browser was involved
+#   os         android, linux, macos, windows
+#   cpu_arch   an architecture as a target triple spells it (aarch64, x86_64), or unknown
+#   gpu        the GPU's vendor as wgpu names it (amd, apple, arm, broadcom, imgtec, intel, mesa, nvidia, qualcomm),
+#              google or microsoft for their software renderers, none where no GPU was involved, or unknown
+#   backend    metal, d3d11, d3d12, vulkan, opengl, opengl-es, none, or unknown
+#   window     normal, private (an incognito window), or none where no browser was involved
+# and may add, as free text: browser_version, os_version, cpu_version (the chip), gpu_version (the model and driver),
+# device (the machine), runtime (what ran the probes where no browser did), defence (a privacy setting in force),
+# reported (what the interface said the GPU was, where that is not what it is), date and source (where the sighting
+# is on record).
+# Each result is keyed by a name its mechanism gives it (a probe, a hash lane) so fields can be added.
+# An interface a browser blocks or does not offer is recorded as an entry with "blocked: true" and a "reason"
+# instead of results, so the registry also shows which browsers withhold which interface, and why.
+# probe_set numbers the probes and inputs the numeric signatures answer. It goes up when either changes, since a
+# signature taken before the change cannot be compared with one taken after.
