	AI and ~~I upgraded~~ MediaWiki		This wiki was upgraded from MediaWiki 1.39.3 to 1.43.8 on 24 May 2026 by Rob, working with an AI agent ([https://www.anthropic.com/claude Claude]). The day before, the same pair ran a smaller rehearsal — a catch-up within the 1.39 long-term-support series — so that the big cross-major-version jump would have as few surprises in it as possible.

			== Day before: the 1.39 catch-up (23 May 2026) ==

			Rather than jump straight from 1.39.3 (May 2023) to 1.43.8, the upgrade was split in two. The first half — catching up to 1.39.13, the final patch release in the 1.39 series — was treated as a dress rehearsal. A few structural changes landed that day to take risk out of the big jump:

			* The <code>vendor/</code> directory was converted from composer-managed to a pinned git submodule, removing Composer from the day-of critical path.
			* The CLI PHP used for MediaWiki maintenance scripts was pinned explicitly to <code>/usr/local/bin/php-8.2</code>.
			* Composer (kept as a fallback) was pinned to version 2.8.3.
			* A small Playwright health-check suite — 11 browser tests against the live site, covering the Main Page, login form, <code>Special:Version</code>, a handful of <code>Art:</code> permalinks, custom-namespace pages, and the missing-page stub — was wired up as a before/after baseline.

			The catch-up went smoothly; all 11 checks passed before, midway through, and after.

			== Day of: the 1.43 jump (24 May 2026) ==

			The cross-major-version jump was largely uneventful, thanks to the previous day's catch-up having flushed most schema migrations through the 1.39.13 maintenance script.

			The high points of the sequence:

			# '''Pre-flight.''' DreamHost's CLI PHP confirmed at 8.2.30; baseline Playwright run came back 11 of 11.
			# '''Read-only.''' Wiki entered read-only mode via <code>$wgReadOnlyFile</code>, pointing at a flag file with a deliberately long, place-named filename (first used on a beach at Hallet Cove the previous day).
			# '''Fresh backup.''' Both the wiki database and the linked art.robnugen.com database, plus <code>LocalSettings.php</code> and the <code>extensions/</code> tree, were zipped together to <code>~/rn.com.back/wiki.rn.com.bak.2026-05-24_022143.zip</code> on the DreamHost server.
			# '''The version flip.''' The <code>LocalSettings.php</code> symlink was removed, the wiki's git checkout was switched from REL1_39 to REL1_43, and <code>git submodule update --init --recursive</code> repopulated <code>vendor/</code>, <code>skins/Vector</code>, <code>skins/MonoBook</code>, and the rest of the bundled extensions at REL1_43's pinned commits.
			# '''LocalSettings.php regeneration.''' The MediaWiki 1.43.8 web installer was walked through to generate a fresh baseline <code>LocalSettings.php</code>, and the customisations from the 1.39 version — custom namespaces (Art, R.O.B.O.T., Writings, Journal, Peeps, Places, Times, and the rest), the <code>ArtRobNugenComPermalinks</code> extension load, the art-DB connection block, the no-anonymous-edit hardening, the 155-year RecentChanges window — were hand-merged on top.
			# '''Schema migration.''' Read-only was lifted, and <code>maintenance/update.php</code> ran the 1.43 schema migrations in 0.7 seconds (most of the heavy lifting having been done by the 1.39.13 catch-up the day before).
			# '''Post-flight.''' The upload-security hardening for <code>images/.htaccess</code> was re-applied; all 11 Playwright health checks passed against the new version.

			== Findings worth recording ==

			Two small things were learned in the process:

			* The old <code>begin_upgrade.sh</code> / <code>finish_upgrade.sh</code> dance of moving the MonoBook skin out of the way before the <code>git checkout</code> and back into place afterwards was found to be obsolete. MonoBook is a proper git submodule on both sides of the jump (REL1_39 pin <code>73c5041</code>, REL1_43 pin <code>7744297</code>), so <code>git submodule update --recursive</code> handles the version flip automatically.
			* The <code>apply-htaccess-hardening.sh</code> script was found to be leaving <code>images/.htaccess</code> at mode 0600 — a quirk of <code>mktemp</code> creating files with that mode and <code>mv</code> preserving the mode onto the target. On DreamHost's shared Apache, that caused every request under <code>/w/images/</code> (including images served through the existing 2023-era hash-bucket symlinks) to return HTTP 403, because Apache fails closed when it can't process an <code>.htaccess</code> file. The fix was a one-line change to the script: a <code>chmod 644</code> after the <code>mv</code>.

			== End state ==

			The wiki is now serving MediaWiki 1.43.8 with PHP 8.2.30 against MySQL 8.0.41 on DreamHost shared hosting. All custom namespaces, the <code>ArtRobNugenComPermalinks</code> extension, and the link into the art.robnugen.com database are intact. The next LTS jump will be to whatever release line is designated LTS after 1.43.
