tools-knowitall-offline

tools-knowitall-offline: minimal standalone filesystem cataloger for hosts with no network path to the real (Postgres-backed) knowitall index -- writes a local SQLite file matching a subset of the real fs_path schema, mergeable later via ON CONFLICT DO NOTHING once network access exists. No sqlx/tokio/workspace dependency by design: it vendors and builds natively on a target host in minutes, not hours, which is the whole point when that host has no internet access either.

What it is for

Pure decision logic for knowitall-offline. No I/O here (that's main.rs): built live against yoda.scity.co (2026-09-13) to catalog a FreeBSD fleet host with no network path to the real Postgres-backed knowitall index. Deliberately standalone (no sqlx/tokio/workspace dependency) so it vendors and cross-/native-builds in minutes on a target host that may itself have no internet access.

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

Item	What it is
`pub const SKIP_DIR_NAMES: & & str`	Directory names skipped when they appear as the CURRENT path's own last component, checked only while descending (never against an explicitly-requested root -- see `should_skip`'s `is_root` handling in `main.rs`'s walk loop)
`pub const SKIP_ABS_PREFIXES: & & str`	Absolute path PREFIXES skipped unconditionally
`pub const SKIP_VIDEO_EXTENSIONS: & & str`	Video file extensions skipped as a heuristic for excluding large DVR/ NVR footage exports reachable via an NFS mount, without needing to know their exact path.
`pub const VAR_DB_NOISE: & & str`	FreeBSD base-system `var/db` subdirectory names that are host state, never "installed program data" -- used when a caller wants to walk a `var/db` directory and keep only the interesting entries (a live `mysql`/`postgres`/`caddy`/`sudo`/..
`fn should_skip(path : & std::path::Path) -> bool`	Whether `path` should be skipped while descending a walk
`fn is_var_db_noise(name : & str) -> bool`	Whether a `var/db`-style subdirectory name is real installed-program state worth cataloging, versus FreeBSD base-system noise.

No pub use re-exports: every item above is declared in this crate.

Boundary

Depends on no other workspace tier.

Shares tier tools with 86 other crates: tools-advisory-reach, tools-archive-guard, tools-artifact-scaffold, tools-ask-ai-core, tools-ask-ais, tools-ask-gemini, tools-book, tools-book-report, … (86 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
