 - **Consequences:** Free users retain non-AI email. Durable/new-message drafts require an owner-filtered database model, bounded API, export/deletion coverage and rollback migration as a separate cohesive increment. Future AI assistance remains Pro/privacy gated.
 - **User approval required:** No; this is repository-local verification and a safety boundary inside approved MAIL-001.
 - **Reversible:** The regression test can be reverted with `7f41cb2`; no runtime/schema state changed. Adding a Pro gate later would be an explicit product change.

+## DEC-054 — Make draft persistence inert before exposing private content
+
+- **Date:** 2026-08-10
+- **Decision:** Add an owner-filtered, revisioned `EmailDraft` tied by cascade to an owned job, with explicit SQLite/MariaDB migration paths, but expose no draft API or UI until readable export and complete deletion implications are covered.
+- **Reason/evidence:** refresh recovery needs server-side ownership, while browser storage and recruiter-message fields violate privacy/domain boundaries. A real-SQLite two-owner test proves isolation and job cascade; backend 625/625, model-current and dual-provider up/down SQL checks pass.
+- **Alternatives considered:** ship schema/API/UI together; use local storage; reuse correspondence or recruiter drafts; persist provider tokens or idempotency attempts in the draft. These make a larger private-data boundary harder to review, expose shared-browser content or conflate delivery state with editable content.
+- **Consequences:** migration `20260810075206_AddEmailDrafts` is additive and reversible, but production must not expose drafts until export/deletion coverage and a bounded owner/job-validating API are verified. A full blank SQLite migration rehearsal remains blocked by the pre-existing JT-019 historical-chain defect, not this migration.
+- **User approval required:** No; MAIL-001 authorizes repository-local durable drafts and no production migration/provider action occurred.
+- **Reversible:** Downgrade the migration before reverting `14b396a`. No reachable application behavior exists in this increment.

 - **Deployment status:** Gitea pull-request run 609 passed the complete CI job in 4m20s. Deploy was intentionally skipped because the workflow deploys only a `push` to `main`; live remains unchanged. No merge/deployment was performed directly, no production migrations were run and the AI operation worker remains disabled by default.
 - **Production status:** Unchanged and unverified. No provider/model call, model pull, external request or paid API occurred.
 - **Known regressions:** None found by automated/local browser checks. Jest still needs `--forceExit` and reports its existing open-handle notice. Email-provider/send tests are fake/local only; real delivery is not claimed. Current MAIL browser evidence is 1280×720 only because the browser surface could not resize or perform native Tab traversal. Interrupted attempts are aged after 15 minutes and notified without retry; the five-minute scan is unmeasured on a large ledger. Direct clean EF-only SQLite migration still hits the pre-existing historical blank-chain defect before later migrations; normal startup owns reconciliation. Cross-feature monthly AI usage accounting remains a rollout gap.
