LAYER: PRODUCT_MAPPING (not Enterprise AI Core; not Organization Overlay)

CORE-06のconfiguration bundle、version、digest、lineage、environment diff、canary、rollbackを、Gemini Apps/Gems、Gemini API、Vertex AI Prompt Managementへ対応づける。UIの保存、prompt version、model名、restore機能の存在を、composite release bundle、backend behavior再現、tenant adoption、組織承認の証拠へ昇格しない。CORE-06のlocal 19/19 profileはprovider-neutral referenceとして保持する。

• ROW: PM-C06-GEM-001; Core contract: configuration entity; Gemini surface / current evidence: Gemini AppsのGemはname、instructions、Knowledge filesを保存・編集・削除でき、previewを持つ; Mapping decision: GemをUI configuration entityとして記録する。ただしGem名をimmutable identity、Saveをapproved release、previewをproduction acceptanceとみなさない; Required verification / UNKNOWN: immutable version ID、parent、digest、semantic diff、approval binding、activation recordは公開HelpでUNKNOWN

• ROW: PM-C06-GEM-002; Core contract: mutable source / current readback; Gemini surface / current evidence: Drive fileをKnowledgeへ追加した場合、Gemはそのfileのmost recent versionを使い、変更がGemへ反映される; Mapping decision: source linkはmutable dependencyとして扱い、Gem instructionsが不変でもsource snapshot/version/digestを別ledgerへ固定する; Required verification / UNKNOWN: 実index更新時刻、cache、古いversion指定、current composite digest、rollback整合はUNKNOWN

• ROW: PM-C06-GEM-003; Core contract: ownership / sharing / drift; Gemini surface / current evidence: shared Gemのviewerはinstructions/filesを閲覧でき、editorはinstructions/files変更・削除・再共有が可能。work/school共有はDrive sharing settingsに依存し、shared GemsはDriveへ保存される; Mapping decision: owner/editor/share stateをconfiguration surfaceの一部とし、editor変更をrelease event候補として外部ledgerへ記録する。viewer/editor権限をrelease approver roleと同一視しない; Required verification / UNKNOWN: edit auditのsemantic diff、approval、notification、version rollback、tenant admin configurationはUNKNOWN

• ROW: PM-C06-GEM-004; Core contract: prompt version / composite version split; Gemini surface / current evidence: Vertex AI Prompt Managementはprompt resourceとprompt versionをcreate/get/list/delete/restoreできる。PromptDataはmodel、contents、generation config、tool config/tools、safety settings、system instruction、variablesを持つ; Mapping decision: prompt_id + version_idをprompt-component provenanceとして採用し、取得したPromptDataをcomposite bundleへ取り込む。Prompt versionだけでdeployment、source snapshot、external policy、eval acceptanceを充足したとみなさない; Required verification / UNKNOWN: version immutability semantics、IAM/audit/retention、cross-project promotion、release approval、deployed runtimeとのbindingは採用環境で検証

• ROW: PM-C06-GEM-005; Core contract: rollback / restore split; Gemini surface / current evidence: Vertex restore_version()は過去prompt versionをlatestとして復元する。prompt全体削除は全versionを削除し復元不能と明記される; Mapping decision: restoreをprompt-component復元として記録し、model availability、tool/source/environment、deployment、data/schema、final behaviorをread backして初めてrelease rollbackを受理する; Required verification / UNKNOWN: restore後のruntime deployment更新、traffic切替、external source/tool互換、business acceptanceはUNKNOWN

• ROW: PM-C06-GEM-006; Core contract: model identity / drift; Gemini surface / current evidence: Gemini APIはstable、preview、latest、experimentalを区別する。specific stableは通常変わらずproduction推奨、latestはreleaseごとにhot-swapされる; Mapping decision: model string、lifecycle class、access date、API revisionをbundleへ保存する。latestはmoving dependencyとしてfixed sentinelを再実行し、stableもexact backend build不変とは表現しない; Required verification / UNKNOWN: UI表示modelのbackend revision、provider内部policy/build、silent fallback、tenant rollout timingはUNKNOWN

• ROW: PM-C06-GEM-007; Core contract: API/application configuration; Gemini surface / current evidence: Gemini APIのsystem instruction、generation parameters、tools、safety等はrequest/application configurationとして扱う; Mapping decision: application repository/registry側でcanonical serialization、digest、owner、approval、environment、eval/run linkを保持する。API call successをconfiguration release acceptanceにしない; Required verification / UNKNOWN: provider-native composite registry、request-to-deployment lineage、organization secrets/policy、actual canary/rollbackはimplementation/ORG値

• ROW: PM-C06-GEM-008; Core contract: surface parity; Gemini surface / current evidence: Gem、Gemini Apps chat、Gemini API、Vertex Prompt Managementは別surfaceで、同名model/instructionsでもconfig field、sharing、state、tool/source capabilityが異なる; Mapping decision: UI→API、Gem→Vertexのコピーを同一versionとして扱わず、surface migrationごとにenvironment diffとsentinel evaluationを要求する; Required verification / UNKNOWN: semantic parity、hidden defaults、tool/source migration、structured-output差はfixed-version testまでUNKNOWN

• Surface: Gemini Apps Gem; Declared/editable: name、instructions、Knowledge、preview、share; Version/readback evidence: current UI entityとDrive保存は確認。immutable version/digest/diffは公開Helpで未確認; Rollback evidence: public Helpでcomposite rollback未閉鎖; Composite release disposition: external ledger + immutable instructions/source manifest + sentinel

• Surface: Gemini Apps chat; Declared/editable: visible prompt/response/model label; Version/readback evidence: conversation表面のみ; Rollback evidence: configuration rollbackではない; Composite release disposition: test observationだけ。release registryにしない

• Surface: Gemini API; Declared/editable: request fields/model string/application code; Version/readback evidence: application側で保存・digest可能; Rollback evidence: application deployment次第; Composite release disposition: app-owned composite bundleが必要

• Surface: Vertex Prompt Management; Declared/editable: PromptData、prompt/version ID、get/list; Version/readback evidence: saved versionを取得可能; Rollback evidence: prior prompt version restoreあり; Composite release disposition: strong prompt-component provenance。release全体は別ledger

• VERIFIED_PUBLIC_SPEC: Google一次資料。Gem create/edit/Knowledge/share、Vertex Prompt Management、Gemini model lifecycleを2026-09-07 JSTに再確認。

• PRODUCT_COMPONENT_VERSION: Vertex prompt_id/version_id。prompt componentのversionでありcomplete release identityではない。

• MUTABLE_DEPENDENCY: Gemが参照するDrive fileのlatest内容、Gemini API latest alias、Gem editor変更。

• SAFE_UI_OBSERVATION: CORE-02の新規chat synthetic logs。Gem/Gem configuration、cross-session、rollbackを支えない。

• PINNED_LOCAL_REFERENCE: CORE-06 19/19。Gemini/Vertex実装試験ではない。

• UNKNOWN: Gem semantic history/export/diff/digest/rollback、hidden backend build、tenant settings、deployment binding、organization release values。

Gem、Gemini API、Vertex Prompt Managementを別configuration surfaceとして整理した。Vertex prompt version/restoreをprompt-component provenanceへ限定し、Gemのmutable Knowledge/editor、API latest alias、surface migrationをdrift対象へ置いた。full composite export、semantic diff、deployment binding、behavior再現、tenant値は推測せずUNKNOWNを維持する。PM-GEMINI-CORE-06はcurrent public evidence範囲でbounded closeする。
