The browser port of the inspection resolver now answers every record set the server does, so no path is left to the server any more: - several sampler candidates, with the identical-branch rule (#270): a compare grid whose branches all resolve to one pair (text and recipe) is resolved, any other mix is ambiguous; - stages whose outputs reach only previews are dropped first; - detailer stages are judged with the samplers in their image ancestry (multistage-differs, cycles, depth and the per-stage visit budgets), and a sampler that only feeds detailers is not a candidate of its own; - A1111 `parameters`, with Python's multiline anchors, `\s` and Unicode `\d`, the bare footer and Template trailers, counted in code points. The parity corpus gains the selection cases and a seeded fuzzer, and every inspection vector now gives the server's prompts, resolution and facts locally. 16 of 17 mutations are caught; the uncaught one (not flattening an ambiguous upstream stage) cannot change any answer.
