Reported: logged in, go to an edit page, then press Home — nothing happens.
Root cause (browser-DOM trace): a boosted nav home→post morphs a home footer <a> into the
post's "edit" link (morph reuses nodes positionally). morph-node's sync-attrs then STRIPS any
attribute the old node has but the SERVER node lacks — which removes the boost's
client-injected sx-swap="innerHTML" (the server never sends it). With sx-swap gone the swap
defaults to outerHTML, so clicking edit REPLACES #content (the <div id=content>) with the edit
fragment's <div> (no id) — DOM trace: "sx-boost children [NAV, DIV#content]" → "[NAV, DIV]".
#content is destroyed, so every later boosted nav (Home) fetches but has no swap target
("post-swap: root=nil") → nothing updates.
Fix: sync-attrs no longer removes the boost's injected navigation attributes (sx-target /
sx-swap / sx-push-url / sx-get / sx-select) when the new (server) node lacks them — they're
identical across all boosted links, so a reused node keeps sx-swap="innerHTML" and the swap
morphs #content's children instead of replacing #content. Recompiled the web stack. Pairs
with a511b21d (fresh href) + 88f8b427 (SX-Redirect) — three facets of the morph-node-reuse
problem (stale href, lost swap attr, guarded-redirect clobber).
TEST-FIRST: added a 3rd boost-nav.spec.js case (LOGGED IN: home→post→edit, assert #content
survives + Home works). Reproduced RED via DOM traces (#content count 0), GREEN after — on the
ephemeral server AND live. No regressions: picker 3/3 + block-editor 1/1.

Reported: on blog.rose-ash.com, home --boosted nav--> a post --click "edit"--> lands on
/tags (a HOME footer link), not /<slug>/edit; subsequent navs stop updating.
Root cause: an innerHTML boost swap uses morph-children, which REUSES DOM nodes in place
(matched positionally when links have no id). The home footer's <a href="/tags"> element is
re-purposed as the post's <a href="/compose-demo/edit"> — its href attribute is rewritten,
but bind-client-route-click had captured the OLD href in its click closure, and the element's
is-processed? mark survived the morph (so boost-descendants skipped re-binding it). Clicking
the reused "edit" link fired the stale /tags closure.
Fix: bind-client-route-click now reads the href FRESH from the element at click time
(dom-get-attr link "href", falling back to the captured value) instead of trusting the
closure. A reused node then always follows its CURRENT href — robust to morph reuse without
needing to clear marks or remove listeners. Recompiled the web stack (.sxbc + manifest).
TEST-FIRST: lib/host/playwright/{boost-nav.spec.js, run-boost-nav-check.sh} reproduces the
exact flow (home -> boosted nav -> click edit -> assert URL is /compose-demo/edit, NOT /tags)
against an ephemeral server. Confirmed RED before the fix (landed on /tags), GREEN after. No
regressions: relate-picker 3/3 (incl. boosted-nav populate) + block-editor 1/1 still pass.
