Our own backlog: 98.9% of our highest-priority tier has never been reviewed

By Alpha Lay ·

The preceding pieces covered what the data says. This one covers how unreliable the data itself is — including the part we caused.

Where the data comes from

Every case carries three status fields:

Finding 1: 95.1% of records are in a "pending review" state

Record statusCasesShare
Searchable, pending semantic review1,21295.1%
Metadata conflict, pending check403.1%
Composite comparison sample221.7%

Not one case is in a "fully reviewed" state. The schema has no such value — we set the goal at "searchable" from day one, and review became permanent debt.

Finding 2: 707 records only ever reached "automatic candidate", and the two flags are the same set

Quality flags:

FlagCases
Tags are automatic candidates707
Cloud ffmpeg technical evidence this round707
Mode unverified324
Short prompt51
Metadata conflict40
Weak classification basis26
Composite comparison frame22
Shot-by-shot coverage under 90%5

The first two have identical counts, and they are the same 707 cases. Not a coincidence: it means those 707 went through one processing path — cloud ffmpeg technical extraction only, with all tags from automatic candidates, and no human review whatsoever.

What about the other 567?

Cases
Not automatic-candidate (a different path)567
Of which "searchable, pending review"505
Of which "composite comparison sample"22
Of which "metadata conflict"40

Among those 567, 454 come from provenance "verbatim from the original publisher" — tags taken directly from source text, more reliable than automatic candidates, but still never semantically reviewed.

Finding 3: The tier we labelled highest-priority is the least reviewed

This is the admission we owe most. The priority field splits cases into three tiers; P0 is defined as "current short drama" — by our own stated intent, the tier most important to understand, and most important to review first:

PrioritySamplePending semantic reviewShare
P0 (current short drama)26326098.9%
P1 (cross-genre technique)44142496.1%
P2 (future genres)57052892.6%

The tier we called most important has the worst review rate. This is clearly a process design failure: priority was assigned at collection time, review never got scheduled, so "priority" ended up affecting exactly one thing — the order in which records got indexed — and nothing about quality.

And within P0, 194 cases (73.8%) never even had speech detection run (see the speech piece). The priority field, in our hands so far, has functioned as a label, not as allocation of effort.

Finding 4: A few small but telling quality flags

FlagCasesMeaning
Shot-by-shot coverage under 90%5Frame- or shot-level analysis covered under 90% of the runtime (all of them 16s+)
Weak classification basis26Insufficient basis; prone to misclassification
Metadata conflict40Different sources give different values for one field
Short prompt51Prompt too short to reproduce from

"Shot-by-shot coverage under 90%" is only 5 cases, but all of them are long videos — exactly the category most in need of shot-level analysis. That coincidence is worth heeding: the more complex the long video, the lower our analysis coverage.

What you can do with this

If you cite any of our earlier pieces: treat this as a standing disclosure. The direction of those conclusions is sound (they rely on ori, dur and other objective measurements), but every classification conclusion — genre, technique, style — shares a denominator that is 95% unreviewed.

If you are designing your own annotation pipeline: this is a complete cautionary case. The core lesson: "pending review" must be a bounded queue, never a default state. We turned review into "later, when there is time," and the result is 1,212 records sitting in a queue with the highest priority last.

If you evaluate any auto-annotated dataset: three questions are enough. (1) What share is automatic candidates? (2) How much has been human-reviewed? (3) How was review prioritised? Our answers: 55.5%, under 5%, and wrongly.
