# UAIX Locale Router 3.76.0 hardening report

## Primary outage drivers found

1. **Embedded front-door recovery/health guard**
   - Registered a shutdown handler.
   - Could render public 503 recovery pages after fatal errors.
   - Exposed a public diagnostic REST endpoint.
   - Included recovery flows capable of deleting rewrite rules, disabling plugins, or switching themes through flags.
   - Removed from the package.

2. **Frontend self-repair and loopbacks**
   - Public requests could trigger localized-home loopback checks and `.htaccess` repair logic.
   - This can convert a routing problem or slow loopback into visitor-facing instability.
   - Converted these methods to explicit no-ops and constrained diagnostics to admin/Site Health flows.

3. **Runtime mutation of WordPress state**
   - Install/upgrade work was registered on public `init`.
   - The plugin could mutate the `active_plugins` option to force itself to the front of the load order.
   - Moved install/upgrade work to `admin_init` and removed active-plugin-order mutation.

4. **Custom `.htaccess` architecture**
   - The plugin wrote custom UAIX marker blocks and refreshed WordPress marker blocks.
   - This is fragile on shared hosting, multisite, proxy/CDN, and non-Apache stacks.
   - Replaced with standard WordPress rewrite refresh and legacy-marker removal through an authenticated admin action only.

5. **Hot-path filesystem scans**
   - Translation fallback could scan active theme/plugin source files on cold frontend requests.
   - Dictionary cache fingerprints used full-file hashing.
   - Frontend now reads prepared runtime dictionaries, avoids source scans, and uses cheap file-stat fingerprints.

## Hardening changes made

- Bumped plugin version and readme stable tag to `3.76.0`.
- Removed `includes/site-health-guard.php` from the package.
- Removed top-level inclusion of the health guard.
- Changed default new-install routing state to disabled.
- Changed new-install redirect default to `302`.
- Restricted install/upgrade tasks to admin execution.
- Removed active plugin load-order mutation.
- Made frontend handoff self-healing an explicit no-op.
- Rewrote `.htaccess` management to rely on the standard WordPress block.
- Added legacy UAIX `.htaccess` marker detection/removal.
- Converted the general repair tool to use a soft rewrite cache refresh.
- Added fallback handling for failed `preg_replace_callback()` calls.
- Prevented content token rendering when plugin routing is disabled.
- Stopped public bootstrap-failure paths from writing options on every frontend request.
- Stored uploaded dictionaries in runtime-key format so frontend reads do not scan source files.
- Added an admin upgrade migration for existing source-text dictionaries.
- Added stricter upload error and post-read size checks for dictionary JSON files.
- Added a hardening notes document in `docs/HARDENING.md`.

## Validation performed

- PHP syntax linted every PHP file in the plugin.
- Verified the release ZIP does not include the removed health guard, `includes/`, `vendor/`, `node_modules/`, `.git`, tests, or runtime log folders.
- Verified package version alignment between the main plugin header, `UAIXLR_VERSION`, Composer metadata, and `readme.txt` stable tag.

## Remaining release caveats

- I did not run a full WordPress integration test matrix inside this environment.
- I did not raise `Tested up to` beyond the original value because that should only be done after a real WordPress-version compatibility pass.
- Before marketplace submission, run WordPress Plugin Check and PHPCS/WPCS in CI against the target WordPress/PHP matrix.

Why This File Exists

This is a memory-system evidence file from uaix.org. It is shown here because AIWikis.org is demonstrating the real source files that make the UAIX / LLM Wiki memory system work, not only summarizing those systems after the fact.

Role

This file is memory-system evidence. It records source history, archive transfer, intake disposition, or another piece of provenance that should be retrievable without becoming an unsupported public claim.

Structure

The file is structured around these visible headings: UAIX Locale Router 3.76.0 hardening report; Primary outage drivers found; Hardening changes made; Validation performed; Remaining release caveats. Those headings are retrieval anchors: a crawler or LLM can decide whether the file is relevant before reading every line.

Prompt-Size And Retrieval Benefit

Keeping this material in a separate file reduces prompt pressure because an agent can load this exact unit only when its role, source site, category, or hash is relevant. The surrounding index pages point to it, while this page preserves the full content for audit and exact recall.

How To Use It

• Humans should read the metadata first, then inspect the raw content when they need exact wording or provenance.
• LLMs and agents should use the source site, category, hash, headings, and related files to decide whether this file belongs in the active prompt.
• Crawlers should treat the AIWikis page as transparent evidence and follow the source URL/source reference for authority boundaries.
• Future maintainers should regenerate this page whenever the source hash changes, then review the explanation if the role or structure changed.

Update Requirements

When this source file changes, update the raw source layer, normalized source layer, hash history, this rendered page, generated explanation, source-file inventory, changed-files report, and any source-section index that links to it.
