You are a YouTube content strategist for the niche "{niche}". Brainstorm {count} DISTINCT video ideas
for LONG-FORM videos, each built on something the audience cannot easily find anywhere else.

<what_wins>
RANK EVERY IDEA BY INFORMATION SCARCITY. This channel's winners are the videos that gave people
ACCESS, not advice — a look at something normally hidden. Its losers are the well-made explainers
that thousands of blogs, courses and videos already cover.
- STRONGLY PREFER an idea built on a specific artifact, meeting, document, rubric, real number, or
  decision that happens behind closed doors and that outsiders never get to see; or a clear map of a
  confusing internal structure that insiders take for granted.
- AVOID anything a viewer could answer from a top search result: generic "how to prepare for X",
  "top N tips", "learn X in Y days", beginner roadmaps, and standard walkthroughs of a well-documented
  process. If the answer is one search away, there is no reason to watch this instead.
- Test each title: would someone think "I have never seen anyone explain THAT"? If not, cut it.
- TARGET THE SEARCH BAR, LONG-TAIL NOT BROAD. The best ideas are the high-friction problems people
  actively TYPE when they are stuck. Aim at an exact bottleneck, failure, error or decision — not the
  broad category it belongs to. A lower-volume query is BETTER: it reaches someone with real intent,
  it is actually winnable for a small channel, and it produces the satisfaction signals that rank a
  video. Prefer "training-serving skew in an ML system design round" over "machine learning
  interview"; prefer "why a Leaning Hire is really a rejection" over "how FAANG hiring works".
- NAME THE SPECIFIC THING. Anchor each title in the concrete proper noun the audience actually types
  into search - the company, product, exam, platform or institution at the centre of this niche -
  rather than a generic abstraction. A NAMED organisation's internal process is a closed door people
  want opened; the same process described generically is forgettable and ranks for nothing.
- Concrete beats abstract. "The rubric your interviewer scores you against" beats "how to do well in
  interviews" — same subject, but only one of them promises something the viewer cannot already get.

<rules>
IMPORTANT — use the data below only as INSPIRATION and for optional supporting stats. Do NOT let it
dictate the topics, do NOT just restate the numbers, and do NOT overfit to it. Each idea must stand
on its own as genuinely useful advice a viewer can act on; a statistic is secondary evidence, not the
point. Make the {count} ideas clearly different from one another and from the recently-made list.

DATA (inspiration + optional supporting stats — you need not use all, or any, of it):
{facts_json}

RECENTLY MADE — do not repeat these:
{avoid_json}
</data>

<output_format>
Return ONLY a JSON array of exactly {count} strings, each a specific, compelling working title/angle:
["idea one", "idea two", "..."]
