-- **Exact current task:** MAIL-001 — design and implement the bounded authenticated draft API over the now-exportable tenant-owned store; do not wire UI until API isolation/concurrency tests pass.
-- **Last completed step:** complete readable draft coverage for encrypted on-demand and hashed per-owner daily exports was committed/pushed as `2fa4e38`; focused 4/4 and backend 625/625 pass.
-- **Files currently modified:** authoritative MAIL-001 tracking/evidence only; persistence/export code is committed.
+- **Exact current task:** MAIL-001 — connect reply/new-message UI to revisioned server drafts with refresh recovery and explicit conflict handling; preserve the existing send confirmation boundary.
+- **Last completed step:** bounded authenticated draft CRUD was committed/pushed as `a9bb22e`; focused real-SQLite 4/4, backend 629/629 and build pass with no provider/send side effects.
+- **Files currently modified:** authoritative MAIL-001 tracking/evidence only; persistence/export/API code is committed.
 - **Commands already run:** dependency/audit/router/full frontend/build; legacy follow-up/export/recovery/provider suites; full backend; Gitea run inspection; Playwright; MAIL context/unlink/provider-state/Free-policy/draft-persistence focused and full suites/build; EF model-current and dual-provider up/down scripts. See V-126–V-146.
 - **Test results:** npm audit 0 vulnerabilities; Gitea pull-request CI PASS in 4m20s at run 609; backend 625/625; frontend 50/50 suites and 194/194 tests; Playwright 4/4; production build passes. Draft isolation/cascade 1/1; EF model current; SQLite/MariaDB draft up/down scripts pass. Full blank-chain SQLite apply fails earlier in `AddJobEntityAndProspectStages` on missing `LastReminderEmailSentAt` (JT-019).
 - **Services currently running:** none on task-owned ports 3000/5202. Playwright stopped its disposable API/Next servers. Pre-existing Docker services were not changed.
 - **Temporary files or processes:** no task-owned process is running and the failed disposable migration database was removed. Existing synthetic browser evidence/account and startup-created local backup remain documented. No provider account, real email, private content, paid service or production service was accessed.
 - **Production changes currently active:** none. No deployment, migration, provider connection/sync/send or production payload occurred.
 - **Rollback status:** downgrade `20260810075206_AddEmailDrafts` before reverting `14b396a`; then follow the existing MAIL rollback order (`ee5ef7e`, `449faeb`, `123fc55`/`e9937ac`, ledger downgrade before `653f011`). No production migration/deploy/provider grant occurred.
-- **Uncommitted changes:** tracking/evidence for `2fa4e38` and V-147 only; commit and push before the draft API increment.
+- **Uncommitted changes:** tracking/evidence for `a9bb22e` and V-148 only; commit and push before the draft UI increment.
 - **Known failures:** live deployment is not verified because PR deploy is intentionally skipped and the active branch is not approved for merge. Draft export/API/UI, full thread/category actions and non-Gmail review remain; existing accounts need re-consent and IMAP stays read-only. A clean full-chain SQLite apply fails in the pre-existing JT-019 migration before the new draft migration. Browser/provider/MariaDB/production unavailable or unverified; recovery scan performance is unmeasured at large ledger scale; Jest open handles; SEC-006 parser dependency work is still separately gated; parser isolation remains SEC-007.
-- **Exact next action:** add authenticated list/get/create/update/delete draft endpoints with owned-job validation, bounded plain-text fields, revision conflict handling and two-user direct-ID tests. Keep content out of logs, notifications and browser storage; no provider call or send occurs on save.
+- **Exact next action:** inventory the correspondence composer state and API client, then add explicit Save draft/resume/delete/new-message UI with visible revision conflict/reload. Do not autosave silently until race/navigation behavior is covered; sending must still require the existing confirmation and idempotency UUID.
 - **Work that can continue independently:** remaining MAIL-001 repository work and later UX packages. SEC-006/007 await package-index permission; PROD-001/003/004 await production access.
 - **Decisions still required from the user:** none for synthetic/code-inspected repository work. Any provider connection or send test, internet/package upgrades, private data, external/paid providers and production actions retain explicit approval/safety gates; SEC-009 retention/legal policy remains unresolved.
