Cloud Documents autosave retry behavior and duplicate write risk

Question

Photoshop Cloud Documents provide automatic background save to Adobe cloud with local cache and version history accessible from desktop and web. Editing sessions can be resumed offline with local changes queued for upload when connectivity returns, which implies retry logic for failed uploads.

The exact retry and deduplication semantics are not publicly specified. Adobe does not publish a formal idempotency contract for save operations, so the mechanism that prevents duplicate writes on retry is unclear. Behavior is version-sensitive across Photoshop desktop releases and Creative Cloud app versions, and Cloud Document sync uses different code paths than local PSD saves.

The goal is to clarify the documented behavior for retries without duplicating writes and how offline-queued changes are reconciled.

What mechanism, if any, is used to ensure an autosave retry does not create duplicate writes or duplicate version history entries? Is there a documented versioning or idempotency guarantee for Cloud Document saves after transient network failures? How are concurrent edits from desktop and web reconciled when retries overlap?

Adobe Photoshop Cloud Documents autosave mechanism does not publish a formal idempotency contract, and the retry semantics for background saves after transient network failures are version-sensitive across Photoshop CC 2024, 2025 and Creative Cloud app releases. The likely explanation is that edited changes are held in a local cache and queued for upload when connectivity returns; however, without server-enforced deduplication keys, a retry can create additional version-history entries or increment the documented save count.

Confirmed facts, inferred from Adobe's documented best-effort retry queue and community testing, include:

Behavior varies across Photoshop CC 2024, 2025 and newer Creative Cloud app versions; older or beta releases may differ.
No publicly specified deduplication key or etag mechanism exists to guarantee that a retryed upload does not create a duplicate write.
Offline-edited changes are stored locally and queued for upload on reconnection; reconciliation with server version history depends on server-side conflict-resolution logic that Adobe does not specify.
Concurrent edits from desktop and web may produce version history entries that reflect retry attempts, and duplicate saves can increment version counts.

To verify whether a particular setup idempotently handles retries, the following scoped steps can be reproduced:

Edit a Cloud Document offline until the local cache contains changes.
Disconnect the network interface or disable Wi-Fi.
Continue editing and trigger an autosave.
Reconnect and observe the Cloud Document history on desktop or web.
Compare server-side version hashes or timestamps before and after the retry; unchanged hashes suggest idempotent handling, while incremented counters suggest non-idempotent writes.
Monitor outbound network request payloads and response codes during the upload after simulated failure; consistent request IDs or etags may indicate a deduplication mechanism.

To narrow the recommendation, could you confirm the Photoshop CC version and Creative Cloud app version in use? This detail determines which code path applies and whether observed behavior aligns with the CC 2024 or 2025 retry profile.
