Release Port Layer 1 v1.2.0 fixes a garbage‑collection bug that caused permanent 404 errors for download messages and adds self‑heal to automatically restore missing content blobs.

Why it matters: Prevents permanent data loss from GC misdeletion; auto‑recovery restores missing blobs on download-message, eliminating user‑facing 404s.

Release Notes

Bug Fixes

Fixed dedup GC incorrectly deleting still-referenced blobs, causing permanent 404 on download-message
Fixed download-message to self-heal when content blob is missing: automatically re-fetches from IMAP and restores the blob; 404 is only returned if the recovery itself fails
Fixed wrong schema field used for attachment hash lookup in cleanup_unused_content

Features

search-messages now supports filtering and sorting by server-controlled timestamps: internal_date (IMAP INTERNALDATE) and ingest_at (archival time), enabling reliable incremental sync cursors
(ui) Strip remote content from emails when viewed #54

Refactor

Migration merge: use searchable_segment_ids() to reduce unnecessary file access (#261)
