Subject: [PATCH 1/3] Cut cross-domain _redirects so docs.pccx.ai stays
 standalone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

docs.pccx.ai is the v002 legacy site now and should serve its own Sphinx
build instead of forwarding visitors to docs.altifigence.com. The
_extra/_redirects file held nine 301 rules that rewrote every page —
/, /*, /en/*, /ko/*, /docs/v002/*, /en/docs/v002/*, /ko/docs/v002/*,
/robots.txt, /sitemap.xml — to corresponding paths under
docs.altifigence.com.

Drop the file entirely. The deploy.yml \"Create root redirect page\"
step is gated on `if [ -f _extra/_redirects ]`, so it now no-ops, and
the Sphinx build's own root index.html (with its same-domain meta
refresh to /en/) keeps the site fully self-contained.

Companion change: pccxai/pccx-vision-v001 was deleted on 2026-05-27 and
v003 / vision-v001 / Lab were removed from this Sphinx tree in #107.
docs.altifigence.com is now the canonical hub for everything beyond
v002; docs.pccx.ai is a frozen v002 archive.

Subject: [PATCH 2/3] docs: retarget v003/tools sidebar + prune roadmap
 later-v003; en-ko sync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- _static/pccx_versions.json: v003 entry now points to https://docs.altifigence.com/v003/
- index.rst, ko/index.rst: dropped Toolchain Demos toctree block; Tools now uses /lab/, /launcher/, /ide/ on altifigence (labels kept English for parity)
- docs/roadmap.md + ko/docs/roadmap.md: removed "## Later — v003.x" section and updated family tree caption
- docs/samples/index.md + ko/docs/samples/index.md: added :orphan: so removal does not break strict build
- conf_common.py, _templates/sidebar/brand.html: updated footer icons
- docs/index.rst, README.md, docs/v002/gemma3n-e4b-integration.rst: refreshed stale tool URLs for link health
- all changes maintain EN/KO structural parity per repo rules

Subject: [PATCH 3/3] docs: open v003 + Tools links in new tabs; correct orphan
 metadata for samples pages

- _static/pccx-version-switcher.js: v003 entry and all external sidebar links (Tools)
  now use target=_blank + rel=noopener (via buildEntry + upgradeExternalSidebarLinks)
- docs/samples/index.md + ko/docs/samples/index.md: use proper "orphan: true"
  YAML frontmatter so removal of Toolchain Demos toctree does not trigger
  "document isn't included" or transition errors under strict -W -n build
- All changes maintain EN/KO parity
