Two changes:
1. New BACKLOG_FILE_BYTES_ENCRYPTION.md captures everything I'd
want to know if I were picking up the file-bytes encryption
work cold in 6 months. ~370 lines, sits next to
DATA_LAYER_AUDIT.md for discoverability.
Sections:
- TL;DR + status (deferred, no production impact yet)
- Goal + non-goals
- Threat model delta table (mode-by-mode)
- Architecture: write path with ASCII flow diagram
- Architecture: read path with ASCII flow diagram
- The six hard parts:
1. Web Crypto AES-GCM doesn't stream → chunked-AEAD wrapper
2. Multipart uploads need coordinated chunking (S3 5 MB minimum
vs. our 1 MB AES-GCM chunks)
3. Resumable uploads + key persistence (new _pendingUploads
table for the in-flight content key)
4. No more server-side thumbnails (three options, recommended:
client-side resize before upload)
5. Sharing complicates the trust model (URL-fragment key
sharing, recommended; Mega.nz / Cryptpad pattern)
6. Migration of existing plaintext files (lazy on-read,
recommended)
- Schema delta (sql + Dexie additions)
- File map (~2200 LoC across 9 new files + 3 touched)
- Testing strategy (unit + integration + e2e per layer)
- Out-of-scope items explicitly listed
- Decision criteria for when to actually do this
- Five open questions for whoever picks it up
- Cross-references to related files
The doc is opinionated where I have a defensible recommendation
and explicit about uncertainty where I don't.
2. DATA_LAYER_AUDIT.md updates:
- Backlog "Offen" item #1 (File-Bytes-Encryption) now points
directly at the new plan doc with a one-line teaser.
- Backlog "Abgeschlossen" gains a row C for the Conflict
