Data and model provenance

Preserved claim

This repository preserves one v0.1 classifier artifact with an independently verified SHA-256. The artifact consumes 6,522-dimensional output logits from the declared BirdNET v2.4 FP16 TFLite backbone.

The exact original per-record training snapshot no longer survives. Therefore this release does not claim to be independently reproducible from raw source media.

Surviving source-family record

Source family	Surviving license information	Release treatment
InsectSet459	Dataset card states CC BY 4.0; source material may also be CC0	Named as a source family; media not redistributed
ESC-50	CC BY-NC 3.0	Named as a source family; media not redistributed
iNaturalist audio	License varies by individual recording	No blanket license asserted; media not redistributed
Private field negatives	Private research evidence	Not redistributed and location omitted
BirdNET backbone	Separate upstream model terms apply	Backbone is not redistributed here

Missing evidence

The following v0.1 records are unavailable:

• exact source-file list and per-record licenses;
• exact normalized window manifest;
• grouped train/evaluation split;
• threshold-selection report;
• complete field-review ledger linked to this exact artifact;
• original environment lockfile.

These gaps are recorded rather than reconstructed from later experimental branches.

Release rule

A future model version must include:

1. artifact SHA-256 and byte size;
2. feature extractor identity and checksum;
3. ordered classes and independent thresholds;
4. source/window manifest digest;
5. per-record source and license provenance;
6. grouped split policy and seed;
7. scoped metrics and known false positives;
8. code commit and runtime source checksum;
9. deployment target and rollback artifact;
10. privacy-reviewed public documentation.

Model outputs remain assertions for review. They do not become confirmed observations without human validation.
