Gemini 3.6 Flash successor gate, media admission, and tool portability
1. 3.6 stay/successor/exit gate
Formula / rule: eligible path = motive evidence + hard gates + matched canary; version recency alone is insufficient.
Dated provenance: Frozen gemini-3-6-flash fixture; defect, regression, tool, overflow, cost, concentration, and private-control motives; surface verification date 2026-08-14.
First-party citation: Google Gemini API documentation
| Fixture | Inputs | Observation / calculation | Decision boundary | State |
|---|---|---|---|---|
| no defect + capability regression | measured defect; successor identity; capability gate; canary owner | No measured defect stays on 3.6; successor regression has no matched media canary. | Recency cannot justify a version move. | UNAVAILABLE — successor canary missing. |
| built-in-tool defect + context overflow | tool result; context size; retained evidence; target admission; rollback | Target fixes tool defect but admits 720K against a 900K fixture. | Tool success does not repair context overflow. | FAIL — split route required. |
| cost ceiling + vendor concentration + private control | declared motive; host; region; artifact; canary; control evidence | Private path has artifact identity; cost and concentration joins are unavailable. | Private control is not evidence of savings or diversity. | PASS WITH SCOPE — private-control motive only. |
2. Multimedia admission-and-reduction suite
Formula / rule: media result = admitted inputs − dropped inputs + citation/checker coverage; missing accounting is Unavailable.
Dated provenance: Frozen gemini-3-6-flash fixture; text, 12 images, image/audio, 90-minute audio, video, mixed media, and overflow; surface verification date 2026-08-14.
First-party citation: Google Gemini API documentation
| Fixture | Inputs | Observation / calculation | Decision boundary | State |
|---|---|---|---|---|
| text + 12 images | asset hashes; preprocessing; admitted count; output reserve; visual checker | 12/12 images admitted after resize; checker flags one low-resolution asset. | Admitted media is not equivalent visual quality. | PASS WITH REPAIR — image review required. |
| image-plus-audio + 90-minute audio | image/audio hashes; sample rate; duration; transcript; citations | Audio transcript joins; token/count evidence is absent for both duration and image. | No usage claim without media accounting. | UNAVAILABLE — count evidence missing. |
| long video + 900K mixed media + overflow | video hash; shard map; admitted/dropped inputs; reserve; reviewer | Video shards are retained; 900K mix exceeds the candidate admitted budget and drops audio. | Dropped audio blocks mixed-media parity. | FAIL — overflow rejected. |
3. Thinking-and-built-in-tool portability pack
Formula / rule: tool portability = control + effective mode + native/external path + event/citation IDs + checker.
Dated provenance: Frozen gemini-3-6-flash fixture; thinking, grounding, code, function, schema, interruption, and cancellation; surface verification date 2026-08-14.
First-party citation: Google Gemini API documentation
| Fixture | Inputs | Observation / calculation | Decision boundary | State |
|---|---|---|---|---|
| omitted/minimum/high thinking | serialized controls; effective mode; output; usage; deterministic checker | Minimum mode settles; omitted and high modes lack effective-mode evidence. | Requested thinking level is not effective thinking level. | UNAVAILABLE — two modes unknown. |
| search grounding + code execution + function calling | tool IDs; citation IDs; sandbox; auth/data flow; event order | Function calls map; grounding citations are external and code sandbox identity is absent. | Native tool parity cannot be inferred from function-call parity. | PASS WITH REPAIR — external grounding. |
| strict schema + interrupted stream + cancellation | schema hash; event sequence; cancel event; stop/usage; checker | Schema checker passes; interrupted stream has no cancellation event or settled usage. | No resume or cost result is inferred. | UNAVAILABLE — stream settlement missing. |
Fail-closed rule: unresolved host, endpoint, artifact, modality, control, citation, workload, acceptance, or accounting joins remain Unavailable; no neighboring route supplies them.
