wiki: Phase E complete - all 6 polish pages
Troubleshooting: organized by category - install/launch (SIGILL, macOS
Gatekeeper, Windows PATH, musl Luau), encoding/format (UTF-8, wrong
delimiter, ragged rows, BOM), index/cache (stale, missing JSONL, Polars
schema drift), memory (OOM, ext-* alternatives, approx algorithms),
specific commands (stats date-whitelist, search case sensitivity, fetch
rate limits, excel edge cases). Plus diagnostics with --version, --envlist,
QSV_LOG_LEVEL, and where to report bugs.
FAQ: short answers to the most-asked questions. qsv vs pandas/DuckDB/csvkit/
miller/xsv, Windows/ARM/IBM platform support, streaming vs in-memory, what
an index/stats-cache/automagical command is, how to update, what features
my qsv has, AI/LLM privacy (no data leaves your machine unless you
explicitly send it), bug-reporting flow.
Comparison: head-to-head with xsv (qsvlite is the drop-in), csvkit (10x
faster), Miller (overlap, both excellent), DuckDB (complement, not
replace - to-parquet hand-off), pandas (qsv as the preprocessing layer),
Visidata (qsv lens is the closest equivalent), awk/sed (qsv understands
CSV quoting). Ends with a "which tool when" cheat sheet.
Glossary: 30+ terms - antimode, asof join, automagical, BLAKE3, cardinality,
CKAN, DataSketches, dyncols, lazy frame, lookup table, MAD, MCP, MiniJinja,
neuro-symbolic, non-equi join, Polars, Polars schema, Pragmastat,
pseudonymization, reservoir sampling, RFC 4180, sortiness, stats cache,
streaming, TOON, t-digest, WKT, XSD.
External-Resources: try-it-online, 100.dathere.com lessons, 5 conference
talks, "Have we achieved ACI?" 3-part blog series, canonical /docs/
links, live benchmark dashboard, Discussions categories, datHere
ecosystem (qsv pro, qsv-recipes, qsv-lookup-tables, qsv-cookiecutter,
DataPusher+), 4 contributed notebooks, packaging across 10 distros,
underlying library credits, Zenodo DOI + DeepWiki + FOSSA, sponsor link.
Contributing-to-the-Wiki: clone+commit+push workflow, page conventions
(H1, tier badge, See also), templates for command-reference and recipe
pages, when-to-update matrix, 10-item verification checklist, commit-
message convention, don't-duplicate-/docs/ guidance, anchor dataset
conventions, slug rules, asset handling, asciinema casts.
All 49 wiki pages now have substantive content. Plan complete.
