The doxa.life script embed was blocked on a server change: the live root
manifest.json answers without Access-Control-Allow-Origin, and the gallery
fetch()es it cross-origin, so no tab could mount. Measured on nuxtbase,
though, the same static layer DOES send ACAO on every path inside a folder
of the tree (doxa-maps-spa/<anything>, even a 404; assets/…).
So generate-tree writes a byte-identical manifest copy at
doxa-maps-spa/manifest.json in the same step as the root one (they cannot
diverge). The gallery reads it FIRST when the tree is on another origin (no
CORS error in the host's console) and the root first when same-origin.
Script URLs still resolve against the tree root, never the copy's folder.
check:gallery-embed:live-cors serves the tree with the live rule
(serve-strict LIVE_CORS=1: no ACAO on the root manifest only).
- The current gallery under it: "did not boot within 60s" (negative
control, reproducing doxa.life).
- With this change: js 14, iframe 14, neighbour 14, linked 4. The default
gate also passes all phases.
check:embed-targets, check:drop and check:public-hygiene pass with the copy
present.
The server-side CORS rule (serving/traefik-embed-headers.yaml) is still the
right long-term fix, and it needs server access. This unblocks the embed
without it once the tree is published.
