The `supply` and `demand` concept tracks each carried one `DEMO — ` card
embedding a public recording from the Cap instance at video.karti.ai. Both are
gone, for two reasons that arrived together.
One of the recordings is no longer there. `sjqqvthbfma27bm` now answers 404 on
both `/s/` and `/embed/`, so "DEMO — What a hold takes off the board" promised
six seconds of teaching and played a dead frame. That is precisely the failure
the comment above these rows was written to record the last time it happened,
and it came back — because the footage lives on an instance this repository does
not control, so no amount of care in this file can keep the claim true. Checked
just now rather than assumed: the surviving id, `1rqq9rk4dpp71fd`, still answers
200.
The other reason is judgement. /learn is the page deliberately shown to people
outside this company, and a `DEMO — ` card sitting beside genuine product
footage makes the whole page read as half-placeholder to exactly the audience it
exists to convince. The previous version of this file argued the opposite — that
an empty track hides the shape of the page — and that was the wrong trade. An
empty concept track renders an empty state saying nothing has been published to
it yet, which is true, and true beats furnished.
`seedLearn` and its call site go with them rather than being left as an empty
array behind live machinery. If those tracks get purpose-shot recordings they
belong in `HOSTED_LEARN_MANIFEST`, rendered by `scripts/learn-film.mjs` like the
platform track, and served by PIG itself.
The two rows were also deleted from production directly, matching what
`clear()` does for prefixed learn rows, so the page is correct now rather than
at the next reseed. The underlying Cap recording is untouched.
