## TL;DR
Do not drop strict mode; fix the underlying warning. Run the build without strict to see the full warning list, fix each one (missing files, bad links, plugin misconfig), then re-enable strict and confirm a clean build.

## The exact error
```text
Aborted with 1 errors in strict mode
```

## Steps
1. **Reproduce without strict**
   Run mkdocs build without --strict and collect the full warning output. Strict mode hides the detail behind the abort message.
   Success check: You have the complete list of warnings that strict mode escalated.
2. **Fix each warning at the source**
   For missing files, add or remove the nav entry. For unrecognized relative links, correct the path. For plugin warnings, fix the plugin config.
   Success check: A non-strict build completes with zero warnings.
3. **Re-enable strict mode**
   Run mkdocs build --strict again and confirm it exits 0.
   Success check: Strict build exits 0 with no output.
4. **Pin strict in CI**
   Set strict: true in mkdocs.yml or pass --strict in the CI build step so regressions fail the pipeline immediately.
   Success check: CI fails on the next warning introduced, not on a later deploy.

## When to use
- Use when mkdocs build --strict aborts and you want to keep the strictness.
- Use when an agent doc pipeline must guarantee warning-free output.

## When not to use
- Not for plugin crashes with tracebacks (those are bugs, not warnings).
- Not for builds that pass without strict but deploy broken pages (that is a content problem).

## Why it happens
Strict mode promotes every warning to a build error. A single dangling nav reference or unrecognized link then aborts the whole build, which is the intended behavior: it forces warnings to be fixed instead of accumulating.

## Edge cases
mkdocs-material adds its own warnings (missing translations, unresolvable social links) that also trigger the abort. The count in the message (1 errors) tells you how many warnings fired; fix them one at a time.
