Problem

Restoring a draft could repeatedly resolve image ownership during unrelated status updates, even when no local stored attachment needed checking.

Solution

Only resolve local ownership when a structured draft includes a relevant local attachment-store image. Preserve retries when the draft returns to local ownership and ignore stale checks from a previous host.

ELI5

Draft images now check whether they still exist only when that check is needed. This avoids extra background work while still preventing missing local images from being sent.

What Changed

• Gate local draft-owner resolution on structured drafts containing local attachment-store paths.
• Keep ownership checks disabled for ordinary paths, paste paths, SSH attachments, terminal scopes, and drafts without images.
• Add coverage for unrelated status publications, host changes during pending checks, and mounted/unmounted rechecks.
• Extract the attachment hook test probe into a reusable test file.

Why

This reduces unnecessary work caused by unrelated app status updates while retaining correct missing-image handling for local restored attachments.

Visual Proof

N/A — this changes background ownership-check scheduling and restored attachment validation without a visual UI change.

Testing

• Added/updated tests in use-native-chat-composer-attachments.test.tsx covering demand-gated checks, host changes, and rechecks.

• I manually tested these changes locally

• Automated tests added/updated, or explained why not below

Review

Agent skill upstream boundary

• Not applicable, or this change copies or mechanically translates no upstream skill-installer source, tests, fixtures, registry entries, path tables, comments, or documentation.

Notes

No known issues in security, cross-platform support (Linux, Windows, macOS), Remote SSH, mobile, backwards compatibility, or performance. The change reduces unnecessary ownership-resolution work.

Checklist

• This PR is small and focused
• I explained what changed and why (ELI5, the user-facing before/after, the mechanism, and why over the alternatives)
• Before/after screenshots or videos attached for UI changes, or N/A with reason
• Self-reviewed for correctness, security, and performance
• Cross-platform, SSH/remote, and path/shortcut impact considered (or N/A)
• pnpm lint, pnpm typecheck, pnpm test, and pnpm build pass (or CI will cover; local preferred)

📝 Walkthrough

The attachment hook now grants local-store authority only when its active checks include an eligible unconnected agent-session attachment-store image, while retaining the existing scope and owner conditions. Tests use a shared React probe and cover validation across attachment types, host changes, unrelated status updates, and upload sweeps with the composer mounted or unmounted.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to fe31e

The ownership gate preserves restored-image checks and retries while avoiding checks when there is no eligible pending image. No identified issue blocks merging after normal checks.
