Three R3 findings.
The redactor's segment classes were ASCII `\w`, so `/数据/客户/秘密视频.mp4` and
`/data/客户/secret.mp4` went out verbatim — and the generic redactor also feeds
CLI telemetry and producer observation messages, where no known-path list
compensates. Segments are now defined by their delimiters instead of an
alphabet, which is correct for every script by construction rather than
requiring Unicode classes to be kept correct. The bare-relative lookbehind had
the same ASCII assumption and let a match start mid-token, redacting
`客户/秘密/视频.mp4` to `客户[path]`; it is now a token boundary, and
bare-relative runs before absolute so it claims the whole token.
sanitizeProbeFailure cast the rejection reason to Error and read `.message`.
An injected probe can reject with anything, so `Promise.reject("failed")` gave
`undefined` and threw inside the redactor — converting a returned failure
result into a rejected promise. Normalized at the boundary, and
redactKnownPaths no longer throws on a non-string.
The contract only admitted .ts/.js/.mjs/.cjs, so it missed shipped shell and
Python callers. frame_strip.sh passed a user-controlled path as ffprobe's last
positional with no terminator; render-and-composite.sh had four more. Both
fixed, and the sweep now covers .py/.sh. Python list argvs are bracket
literals so they get the same position check; shell command lines get a
separate presence check, because checking position there needs a shell parser
— stated as the weaker guarantee it is rather than implied to be equal.
