stats: document zero_padded_numeric; bump stat count 47 -> 48 Reflects PR #3934 (qsv #3938): the new --zero-padded-numeric flag/column brings the stats summary-statistic count to 48. Document the flag in the main stats page (Aggregation-and-Statistics) and bump the 47 -> 48 count across the pages that cite it. The xsv-vs-qsv-1.0.0 legacy snapshot in Comparison.md and the describegpt 47-token content-type vocabulary are intentionally left as-is.

wiki: adopt GitHub Alerts for callouts across the wiki Convert advisory blockquotes and inline callouts to semantic GitHub Alerts (NOTE/TIP/IMPORTANT/CAUTION): - [!NOTE] for the standard category-page "workflow layer" ledes and other top-of-page orientation / "canonical reference" notes - [!IMPORTANT] for behavior-affecting gotchas (auto approx-stats on OOM, group-by unsupported aggs, MiniJinja filter-errors-as-values, synthesize cross-column correlation, profile always-warn RFC4180) - [!TIP] for the Binary-Variants TL;DR and Why-qsv "why it matters" - [!CAUTION] for foreach shell-injection risk and joinp --cross blowup Also update the Contributing-to-the-Wiki category template to use the [!NOTE] lede so new pages follow the convention.

wiki: remove the removed `generate` command + correct command count The `generate` command was removed from qsv but still appeared in Command-Reference under "Generators & Utility". Drop the row and rename the section to "Utility" (now containing just `help`). Also corrects the stale "81 commands" claim used across several pages. README's command catalog currently has 71 entries; the standard `qsv` binary reports 68 from `qsv --list`. Replaced fixed counts with "70+" or "every command" / "every qsv command" where a specific number was not load-bearing, plus a Command-Reference note that the exact set depends on the binary variant and feature flags. Pages touched: Command-Reference, Home, Getting-Started, Why-qsv, Selection-and- Inspection, Comparison. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

wiki: add stubs for Phase B/C/D/E pages so sidebar links resolve Adds 39 placeholder pages so every sidebar entry resolves to real content rather than a 404. Each stub declares its tier, the phase it will be filled in, and a one-paragraph preview of what's coming. They link back to Home / Getting-Started / Command-Reference / Cookbook for navigation. Pages added: - Phase B (Command Reference, 13): Command-Reference, Selection-and- Inspection, Transform-and-Reshape, Aggregation-and-Statistics, Joins- and-Set-Ops, SQL-and-Polars, Validation-and-Schema, Conversion-and-IO, Geospatial, HTTP-and-Web, Scripting-Luau-Python, Indexing-Compression- Diff, AI-and-Documentation - Phase C (Cookbook recipes, 12): Recipe-Inspect-Unknown-CSV, Recipe- Clean-and-Normalize, Recipe-Geographic-Enrichment, Recipe-Date- Enrichment, Recipe-CKAN-Integration, Recipe-JSON-Schema-Validate, Recipe-Build-a-Data-Pipeline, Recipe-Stats-to-Insights, Recipe-Fetch- and-Cache, Recipe-Larger-than-RAM, Recipe-Diff-and-Audit, Recipe-Multi- Table-Joins - Phase D (Tuning + ecosystem, 8): Performance-Tuning, Environment- Variables, Stats-Cache-and-Caching, Lookup-Tables, Claude-Cowork-Plugin, MCP-Server, qsv-pro-Spotlight, Integrations - Phase E (Polish, 6): Troubleshooting, FAQ, Comparison, Glossary, External-Resources, Contributing-to-the-Wiki Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
