The catalog fetch now refuses redirects, cancels rejected bodies and reads
through the shared capped reader before the windows-1252 decode. The feed sends
cardinal codes plus B (both), O and null, not BW or diagonals; tests, comments
and docs now say so, with unchanged id-hash fallbacks. Documents the 8-1,200
per-pack range, drops the unverified low-volume compliance claim for facts and
a link to WSDOT's terms, and stops claiming the per-pack defaults fit under
the 4,000 cap: it is filled round-robin.
One WFS/GML XML feed (~135 cameras) aggregating three publishers under a
`font` field: SCT's own highway cameras plus hotlinked Barcelona (IMI) and
Terrassa municipal cameras. Frame URLs are checked against a small host
allowlist rather than one pinned origin, and every non-SCT camera carries
its real owner as a `credit` shown beside the shared provider. The feed
carries no compass heading, so every camera loads at low heading confidence
(same as TfL and Fintraffic), and ground elevation is primed per publisher
rather than one flat prior.
SCT's own frame link needed a workaround: RenderService always 302s to a
second endpoint (TransitCamera) on a Location the upstream hardcodes as
plain http even when requested over https — refused by fetchWithinHost's
same-origin (scheme-included) redirect policy, by design (stops an upstream
steering a host-pinned request into a plaintext downgrade). Separately,
mct.gencat.cat's TLS setup fails the handshake with Node's fetch outright
(ERR_SSL_WRONG_SIGNATURE_TYPE) even though other HTTP clients complete it.
The loader builds the TransitCamera URL itself, over plain http, from
RenderService's sctidcam id, instead of registering the broken upstream
link — the only transport this host actually serves to this runtime.
Verified against the live feed and the production fetch path
(fetchCctvImageFromUpstream): all 135 cameras return real image bytes, 0
false positives. Ambient-card refresh cadence added to src/data/cctvLod.js
(3 minutes), matching the upstream update rate measured empirically (no
change inside 64s, changed within ~90-150s) — the same cadence already used
for Caltrans/TfL/Ontario/TxDOT.
CCTV_CATALONIA_MAX_SOURCES sets the cap and CCTV_CATALONIA_ENABLED=0 turns
the pack off. No overlap with any existing pack (checked catalog.js and the
git history for Spain/Catalonia/Barcelona coverage: none exists).
Verified before this commit: format, check:boundaries, unit suite (3692
tests), and build all green.
