# Automotive Standards Landscape: Signpost (pointers only)

**This is a signpost, not a knowledge pack.** It carries **no source content**:
no reproduced clauses, no synthesised summaries of normative text. ISO 26262,
ASPICE, SAE J3016, and UNECE R155/R156 are Excluded under this repo's
`docs/SOURCE-VETTING.md` (paywalled or no redistribution grant), so none of them
can be reconstituted into a pack. What this skill does: tell you which automotive
standard you want, who owns it, whether it can be packaged, and where to get the
authentic copy.

## When to use
You need to identify, cite, or locate an automotive standard (e.g. "the
functional-safety standard?" → ISO 26262; "the cybersecurity regulation?" → UNECE
R155). This routes you to the authoritative source. The one genuinely open path in
this catalogue is the `nhtsa-vehicle` pack (US Government guidance, not an
equivalent of any excluded row).

**Prerequisites:** none. Plain Markdown.

## How to use
Find your standard below. The **Status** column tells you whether it is
redistributable:
- 🔴 **Excluded**: paywalled or no redistribution grant; buy/download from the
  owner. Cannot be packaged here.
- 🟢 **Open**: an installable pack exists (named in the row).

Where a licence permits citation, the owner's official catalogue page is given in
the Status cell.
