-**Expected status**: warn (several pages, ~2% average difference)
-**Reason**: False positive. The "missing" segments are numbered heading text like "2. Tabbed File Viewer" where Turndown correctly escapes the period (`### 2\. Tabbed File Viewer`) to prevent markdown parsers from interpreting it as a list item. The content IS present in the markdown — the AFDocs checker's text comparison doesn't account for markdown escaping.

The content IS present in the markdown — the AFDocs checker's text comparison doesn't account for markdown escaping. The specific page(s) flagged vary run to run because AFDocs samples a subset of pages.

 ## page-size-markdown / page-size-html
 
-**Expected status**: pass for page-size-markdown; warn for page-size-html (`all-settings.mdx` only)
-**Reason**: The changelog was split into yearly pages in May 2026, resolving the markdown page-size issue. `all-settings.mdx` may still appear in `page-size-html` at 50,088 markdown chars — 88 chars over the 50K warn threshold. This is the comprehensive settings reference page; splitting it would harm usability for a trivial overage.
-**Affected pages** (as of 2026-06-24):
-- `/terminal/settings/all-settings/` — settings reference (50,088 md chars, borderline warn)
-**Action**: Monitor. If it grows substantially past 50K, consider splitting by TOML section. For now, accept as a known exception for the borderline HTML page-size warning.
+**Expected status**: fail (both checks can fail as intentionally-long reference pages grow)
+**Reason**: A small set of pages are intentionally long and cannot be meaningfully split. They now exceed the AFDocs 100K-char hard-fail threshold, so `page-size-markdown` and/or `page-size-html` fail on any run that samples one of them. The `afdocs-fix` skill explicitly treats page-size as a do-not-auto-fix editorial concern.
+**Affected pages** (as of 2026-07-10):
+- `/support-and-community/community/open-source-licenses/` — auto-generated third-party license text (~1.37M md chars). Regenerated by the `release_updates` skill; any manual split would be overwritten. Drives the `page-size-html` max (396K HTML → 121K markdown).
+- `/changelog/2026/` — current-year changelog (~113–130K md chars). Already split by year; the current year grows until year-end rollover. Drives the `page-size-markdown` failure.
+- `/support-and-community/privacy-and-security/privacy/` — comprehensive privacy/legal content (~113K md chars). Kept whole for legal completeness.
+- `/terminal/settings/all-settings/` — comprehensive settings reference. Below the 100K threshold as of this date but historically borderline; monitor.
+**Sampling note**: AFDocs samples ~49–50 of ~345 sitemap pages per run, so which of these large pages surfaces (and whether a check reports fail or warn) varies between runs. Counts in the report will fluctuate accordingly.
+**Action**: No fix. These pages are intentionally long (auto-generated, current-year changelog, or legal). Do not split. Re-evaluate `/changelog/2026/` at year-end when it rolls over to `/changelog/2027/`.
