A dim line at the foot of Settings: `FabledCurator 2026.08.28.1249 · dev`.
This is no longer a convenience. Milestone 318 stopped publishing version
image tags, so an instance's own report is the ONLY answer to "which build is
this?" — there is no registry name left to check it against. Note #3127 §5
says it directly: a wrong answer here has no second source to contradict it.
Three states, kept distinct because collapsing any two of them lies:
not asked yet render nothing
asked, no version render "unknown"
asked, has a version render it
A blank footer reads as "no version", which is a different claim from "I
cannot say". And a failed health call deliberately does NOT mark the build
loaded — a network blip says nothing about the image, and presenting it as
"unknown" would look like a defective build.
Carried on /api/health rather than a new route: it answers at the same cost
(two module constants, no I/O) and TopNav already fetches it app-wide, so a
separate endpoint would mean a second request for two strings.
Both fields are OMITTED when unset rather than sent empty. Absence already
means "cannot say" — an image predating the field says exactly that by not
having the key — so a second spelling would make every reader special-case
it. The pre-existing test asserting the body is EXACTLY {"status": "ok"} is
what keeps a well-meaning `or ""` default from creeping in.
FC_CHANNEL now has one definition. It was read from the environment in
extension.py and would have been read again here; the new build_info module
holds both, and extension.py binds it as a module-level name so existing
tests monkeypatch it exactly as before. Separate from config.py on purpose:
those are operator settings meant to be changed, these describe the artifact.
Channel sits beside the version, never inside it (rule 149), asserted from
both ends. A `-dev` suffix would read as a 0 segment to the extension's
parseInt comparator and make every dev build compare equal — #2993 exactly.
Not hidden, per the operator and §7: the JS bundle and asset hashes
fingerprint the build anyway, and "I'm on 2026.08.28.1249" is the single most
useful line in a bug report.
